    Common terms used in lighting, LED Technology and Glossary

    For those of you who need to understand this new world of LED lighting, there is some vocabulary you will need to know. We have given you some terminology that will help you  understand what its all about.

    LED

    LED stands for "light emitting diode." A diode is an electrical component with two terminals which conduct the electricity only in one direction. With an electrical current, the diode emits a bright light around the small bulb.


    Lumens vs Watts

    LEDs that are bright enough to replace incandescents for business that is, producing the same number of lumens as standard 40- or 60-watt bulbs---typically only use 9 to 12 watts. The U.S. Department of Energy advises that business that want to replace a 60-watt bulb should look for an LED that produces close to 800 lumens; for a 40-watt bulb, look for 450 lumens.


    Ballast

    In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw. Within a second the lamp would overheat and burn out.

    Thee are several types of ballasts,

    Instant start
    An instant start ballast does not preheat the electrodes, instead using a relatively high voltage (~600 V) to initiate the discharge arc. It is the most energy efficient type, but yields the fewest lamp-start cycles, as material is blasted from the surface of the cold electrodes each time the lamp is turned on. Instant-start ballasts are best suited to applications with long duty cycles, where the lamps are not frequently turned on and off.

    Rapid start
    A rapid start ballast applies voltage and heats the cathodes simultaneously. It provides superior lamp life and more cycle life, but uses slightly more energy as the cathodes in each end of the lamp continue to consume heating power as the lamp operates. A dimming circuit can be used with a dimming ballast, which maintains the heating current while allowing lamp current to be controlled.

    Programmed start
    A programmed-start ballast is a more advanced version of rapid start. This ballast applies power to the filaments first, it allows the cathodes to preheat and then applies voltage to the lamps to strike an arc. Lamp life typically operates up to 100,000 on/off cycles when using programmed start ballasts. Once started, filament voltage is reduced to increase operating efficiency.[5] This ballast gives the best life and most starts from lamps, and so is preferred for applications with very frequent power cycling such as vision examination rooms and restrooms with a motion detector switch.

    Hybrid
    A hybrid ballast has a magnetic core-and-coil transformer and an electronic switch for the electrode-heating circuit. Like a magnetic ballast, a hybrid unit operates at line power frequency—60 Hz in North America, for example. These types of ballasts, which are also referred to as “cathode-disconnect ballasts”, disconnect the electrode-heating circuit after they start the lamps.


    HID/HPS

    High Intensity Discharge bulb. These include the Metal Halide (MH) and High Presure Sodium (HPS) among other types of bulbs that use a mixture of gases that when electrically excited produce an arc that emmits light.

    The color of the light depends on the gases used in the arc tube.


    UL

    Underwriters Laboratory is the certification which indicates that a product meets certain standards that conform with insurance company requirements for safety. An LED bulb without this designation is not of high enough quality for insurance purposes and usually indicates an inferior product.


    Kwh

    Kilowatt per hour is how you are billed by your electric company. There is a cost per Kwh on your electric bill.

    A

    Additive Color Model
    A type of RGB color model that describes how different proportions of red, green, and blue light combine to create colors. In the additive color model, combining red, green, and blue light produces white light.
    Ambient Temperature (Ta)
    The air temperature surrounding the device.
    Ampere (Amp)
    The unit for measuring rate of flow of electrical current: Current (Amps) = Power (Watts) / Voltage (Volts)

    Ballast
    In a fluorescent lighting system or HID bulbs, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw. Within a second the lamp would overheat and burn out.

    Bin (Binning)
    LED manufacturers sort their products into bins based on lumen output and color. Fixture manufacturers specify a range of bins from which they will accept LEDs. If they only accept fixtures from bins that are very close together, the diodes are more expensive, but result in a higher quality fixture. If fixtures are built with LEDs from a wider range of bins, cost and lead-time are reduced. Manufacturers may refer to their “tightly binned” products when they want to convey that theirs is a good quality product.

    Black Body / Black Body Radiator
    An object that absorbs all electromagnetic radiation falling on it. Because it reflects no light, a black body appears black. As a black body is heated to incandescence, it radiates light in a sequence of colors, from red to orange to yellow to white to blue, depending on its temperature. This color sequence describes a curve within a color space, known as the black-body curve.

    Black Body Curve
    A curve within a color space describing the sequence of colors emitted by a black-body radiator at different temperatures.

    Brightness
    Often used incorrectly with respect to illumination as a synonym for luminous flux, an objective measurement of the visible power of a light source. The term is correctly used when describing screen brightness in a display or television. (see Nits).

     

    C Top

    Case Temperature
    The temperature measured at the LED package or case.

    Chromaticity
    An objective specification of the quality of a color, independent of its luminance, and as determined by its or saturation and hue.

    Color Definition
    The color of uniformly illuminated objects described using three terms:

    Hue: Describes the situation when the appearance of different colors is similar (e.g. matching blues and pinks).

    Lightness: Describes a range of grayness between black and white.

    Chroma: Describes the degree of departure from gray of the same lightness and increasing color (e.g. red, redder, pure red).

    Color Gamut
    The range of colors within the CIE Chromaticity Diagram included when combining different sources.

    Color Model
    An abstract mathematical model describing the way colors can be represented as groups of values or color components. RGB (Red-Green-Blue) is a color model with three color components, and CMYK (Cyan-Magenta-Yellow and Key (Black)) is a color model with four color components.
    Color Rendering
    A general expression for the effect of a light source on the color appearance of objects.
    Color Rendering Index (CRI)
    A measure of the degree of color shift objects undergo when illuminated by the light source as compared with those same objects when illuminated by a reference source of comparable color temperature. The reference source has a CRI of 100.

    Color temperature
    The description used to describe the effect of heating an object until it glows incandescently, the emitted radiation, and apparent color, changes proportional to the temperature; easily envisioned when considering hot metal in a forge that glows red, then orange, and then white as the temperature increases.
    Conformal Phosphor Coating
    Phosphor application process that uniformly coats the LED chip with phosphor.
    Controller
    A device that controls the output of color-changing and tunable white lighting fixtures. Controllers typically have software components for configuring fixtures and designing and editing light shows, and hardware components for sending control data to fixtures.
    Cool White
    A description of a range of correlated color temperatures.
    Correlated Color Temperature (CCT)
    The absolute temperature of a blackbody whose chromaticity most nearly resembles that of the light source. Usually specified in Kelvin (K). The lower the Kelvin temperature, the warmer the light feels, or appears.

    Directional Light Source
    A light source that emits light only in the direction it is pointed or oriented.
    Driver
    All LED fixtures include an LED driver or power supply. This driver can be integral to the fixture, separate from the fixture or remotely located. Typically, the driver is an important part of every LED system and you should remember it is a factor when using LED fixtures.

    L Top

    LED
    A Light Emitting Diode (LED) is a solid-state semiconductor device that converts electrical energy directly into light. On its most basic level, the semiconductor is comprised of two regions. The p-region contains positive electrical charges while the n-region contains negative electrical charges. When voltage is applied and current begins to flow, the electrons move across the n region into the p region. The process of an electron moving through the p-n junction releases energy. The dispersion of this energy produces photons with visible wavelengths.

    LED Array
    An assembly of LED packages or dies on a printed circuit board or substrate, possibly with optical elements and additional thermal, mechanical, and electrical interfaces that are intended to connect to the load side of an LED driver.
    LED Chip (Chip)
    The light producing semiconductor device that may or may not be incorporated into an LED.

    LED Driver
    An electronic circuit that converts input power into a current source — a source in which current remains constant despite fluctuations in voltage. An LED driver protects LEDs from normal voltage fluctuations, overvoltages, and voltage spikes.

    LED Light Engine
    An integrated assembly comprised of LEDs or LED arrays, LED driver, and other optical, thermal, mechanical, and electrical components.

    LED Luminaire
    A complete lighting unit consisting of LED-based light emitting elements and a matched driver together with parts to distribut light, to position and protect the light emitting elements, and to connect the unit to a branch circuit. The LED based light emitting elements may take the form of LED packages, (components), LED arrays (modules) LED Light Engine, or LED lamps. The LED luminaire is intended to connect directly to a branch circuit.

The dispersion of this energy produces photons with visible wavelengths.

    L70

    L70 describes the brightness of an LED after a number of hours – often 50,000. If a product claims L70 after 50,000 hours, it means that after 50,000 hours of burning (nearly six years if the lights are on 24/7) the lights are now 70% as bright as they were when they were first installed. L70 doesn’t mean anything without the corresponding number of hours. You may also see terms such as L70 at 6,000 hours. Sometimes manufacturers will list L80 (or even L90) at 50,000 hours. This simply means that after 50,000 hours, the LEDs will be 80% (or 90%) as bright as they were initially. Be careful not to confuse L70 with LM79 or LM80.

    LM79

    This IES document applies to LED fixtures (but not to components.) It prescribes the approved method for “Electrical and Photometric Measurements of Solid-State Lighting Products.” In the beginning, LED products were the wild, wild west. Manufacturers claimed just about anything based on their own personal “test procedures.” LM79 gave structure to the chaos and today LM79 compliance can help ensure that you are comparing apples to apples when you read LED product literature.

    LM80

    This IES (Illuminating Engineering Society of North America)document describes the approved method for “Measuring Lumen Maintenance of LED Light Sources.” It applies to bare LED light sources and does not cover complete luminaires (fixtures.) The main story here is usable life. LED sources, like the old metal halide lamps, tend to fade over life instead of “burning out.” Again, when manufacturers are using the same test methodology, you can be comfortable when comparing products.



    Lumen (lm)

    O Top

    Onboard Power Integration
    An approach to power management that integrates the power supply into a fixture’s housing, eliminating the need for an external power supply.

    Organic Light-emitting Diodes (OLED)
    Organic light-emitting diodes (OLEDs) are based on organic (carbon based) materials. In contrast to LEDs, which are small point sources, OLEDs are made in sheets which provide a diffuse area light source. OLED technology is developing rapidly and is increasingly used in display applications such as cell phones and PDA screens. However, OLEDs are still some years away from becoming a practical general illumination source. Additional advancements are needed in light output, color, efficiency, cost, and lifetime.
     

    P Top

    Power Factor
    The active power divided by the apparent power (i.e., product of the rms input voltage and rms input current of a driver).

    Power Factor Correction

    LED

    LED stands for "light emitting diode." A diode is an electrical component with two terminals which conduct the electricity only in one direction. With an electrical current, the diode emits a bright light around the small bulb.


    Lumens vs Watts

    LEDs that are bright enough to replace incandescents for business that is, producing the same number of lumens as standard 40- or 60-watt bulbs---typically only use 9 to 12 watts. The U.S. Department of Energy advises that business that want to replace a 60-watt bulb should look for an LED that produces close to 800 lumens; for a 40-watt bulb, look for 450 lumens.


    Ballast

    In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw. Within a second the lamp would overheat and burn out.

    Thee are several types of ballasts,

    Instant start
    An instant start ballast does not preheat the electrodes, instead using a relatively high voltage (~600 V) to initiate the discharge arc. It is the most energy efficient type, but yields the fewest lamp-start cycles, as material is blasted from the surface of the cold electrodes each time the lamp is turned on. Instant-start ballasts are best suited to applications with long duty cycles, where the lamps are not frequently turned on and off.

    Rapid start
    A rapid start ballast applies voltage and heats the cathodes simultaneously. It provides superior lamp life and more cycle life, but uses slightly more energy as the cathodes in each end of the lamp continue to consume heating power as the lamp operates. A dimming circuit can be used with a dimming ballast, which maintains the heating current while allowing lamp current to be controlled.

    Programmed start
    A programmed-start ballast is a more advanced version of rapid start. This ballast applies power to the filaments first, it allows the cathodes to preheat and then applies voltage to the lamps to strike an arc. Lamp life typically operates up to 100,000 on/off cycles when using programmed start ballasts. Once started, filament voltage is reduced to increase operating efficiency.[5] This ballast gives the best life and most starts from lamps, and so is preferred for applications with very frequent power cycling such as vision examination rooms and restrooms with a motion detector switch.

    Hybrid
    A hybrid ballast has a magnetic core-and-coil transformer and an electronic switch for the electrode-heating circuit. Like a magnetic ballast, a hybrid unit operates at line power frequency—60 Hz in North America, for example. These types of ballasts, which are also referred to as “cathode-disconnect ballasts”, disconnect the electrode-heating circuit after they start the lamps.


    HID/HPS

    High Intensity Discharge bulb. These include the Metal Halide (MH) and High Presure Sodium (HPS) among other types of bulbs that use a mixture of gases that when electrically excited produce an arc that emmits light.

    The color of the light depends on the gases used in the arc tube.


    UL

    Underwriters Laboratory is the certification which indicates that a product meets certain standards that conform with insurance company requirements for safety. An LED bulb without this designation is not of high enough quality for insurance purposes and usually indicates an inferior product.


    Kwh

    Kilowatt per hour is how you are billed by your electric company. There is a cost per Kwh on your electric bill.

    Ballast
    In a fluorescent lighting system or HID bulbs, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw. Within a second the lamp would overheat and burn out.

    Bin (Binning)
    LED manufacturers sort their products into bins based on lumen output and color. Fixture manufacturers specify a range of bins from which they will accept LEDs. If they only accept fixtures from bins that are very close together, the diodes are more expensive, but result in a higher quality fixture. If fixtures are built with LEDs from a wider range of bins, cost and lead-time are reduced. Manufacturers may refer to their “tightly binned” products when they want to convey that theirs is a good quality product.

    Black Body / Black Body Radiator
    An object that absorbs all electromagnetic radiation falling on it. Because it reflects no light, a black body appears black. As a black body is heated to incandescence, it radiates light in a sequence of colors, from red to orange to yellow to white to blue, depending on its temperature. This color sequence describes a curve within a color space, known as the black-body curve.

    A Light Emitting Diode (LED) is a solid-state semiconductor device that converts electrical energy directly into light. On its most basic level, the semiconductor is comprised of two regions. The p-region contains positive electrical charges while the n-region contains negative electrical charges. When voltage is applied and current begins to flow, the electrons move across the n region into the p region. The process of an electron moving through the p-n junction releases energy. The dispersion of this energy produces photons with visible wavelengths.

    L70

    L70 describes the brightness of an LED after a number of hours – often 50,000. If a product claims L70 after 50,000 hours, it means that after 50,000 hours of burning (nearly six years if the lights are on 24/7) the lights are now 70% as bright as they were when they were first installed. L70 doesn’t mean anything without the corresponding number of hours. You may also see terms such as L70 at 6,000 hours. Sometimes manufacturers will list L80 (or even L90) at 50,000 hours. This simply means that after 50,000 hours, the LEDs will be 80% (or 90%) as bright as they were initially. Be careful not to confuse L70 with LM79 or LM80.

    LM79

    This IES document applies to LED fixtures (but not to components.) It prescribes the approved method for “Electrical and Photometric Measurements of Solid-State Lighting Products.” In the beginning, LED products were the wild, wild west. Manufacturers claimed just about anything based on their own personal “test procedures.” LM79 gave structure to the chaos and today LM79 compliance can help ensure that you are comparing apples to apples when you read LED product literature.

    LM80

    This IES (Illuminating Engineering Society of North America)document describes the approved method for “Measuring Lumen Maintenance of LED Light Sources.” It applies to bare LED light sources and does not cover complete luminaires (fixtures.) The main story here is usable life. LED sources, like the old metal halide lamps, tend to fade over life instead of “burning out.” Again, when manufacturers are using the same test methodology, you can be comfortable when comparing products.
