Lamps, Lights & Indicators

The lamps, lights & indicators section refers to components that are basic to the lighting industry–from incandescent lamps to inert gaseous types to solid state construction. Also included are lamp accessories, indicators, and ballast lighting products.
A backlight is the form of illumination used in a liquid crystal display. They illuminate the LCD from the side or back. It is used in small displays to increase readability in low light. It can also be used in computer displays and LCD TVs.
Cold Cathode Lamps (CCFL) do not employ a cathode heater. These fluorescent lamps are popular for LCD backlighting, computer case monitors, and neon lamps. Hot cathodes lamps emit electrons due to thermionic emission and use an electrical filament.
Color filters are usually transparent color gels to add colored light or filter out unwanted color. Most modern gels are made out of a polycarbonate or polyester. Caps are usually placed over lights to prevent the light from shining.
Fluorescent Lamps designed to fit in existing incandescent light fixtures. CFLs may be integrated (combining bulb and electronic ballast), or non-integrated (where ballast is placed in the fixture). CFLs are gradually replacing incandescent lamps.
Electroluminescent Lamps (19 Companies)
Electroluminescence (EL) is an optical and electrical phenomenon in which a material emits light in response to a strong electric field or an electric current passing through it.
Electronic Ballasts (39 Companies)
Electrical Ballast is a device intended to limit or stabilize the amount of current in an electric circuit. Ballasts vary greatly in complexity, from a simple series resistor to a complex computerized, remote-controlled electronic ballast.
Fluorescent Lamps (43 Companies)
A discharge lamp in which gas ionizes and produces radiation that activates the florescent material inside the glass tubing. The phosphors in the fluorescent material transform the radiant energy from the discharge into wavelengths giving more light.
Incandescent Lamps (62 Companies)
Generates light by passing an electric current through a thin tungsten filament wire in a glass bulb filled with inert gas. The wire gets extremely hot, glows, and emits visible light.
Indicator Lights (82 Companies)
Indicator Lights are widely used in a variety of ways. Most electronic devices have indicator lights which show users that a device is on, working, or malfunctioning.
Indicators (61 Companies)
Indicator lamps are used in all types of reporting applications from arrays of LEDs for signal lights, to simple display pointers on panels.
Infrared Lamps (37 Companies)
Infrared Lamps emit infrared radiation, lying outside the visible spectrum at the red end. It uses thermal radiation of wavelengths and is most commonly used in heating and in infrared communication.
Lamp Assemblies & Arrays (42 Companies)
Lamp Assemblies and Arrays are the components that come with and are used in conjunction with lamps and lights. Assemblies and arrays include lamp holders, ballasts, reflection cups, wires, and the lamp itself.
Lamp Drivers (20 Companies)
Lamp Drivers are electrical devices that produce and sustain pulses in a circuit.
Lamp Sockets & Assemblies (57 Companies)
Lamp Sockets produce artificial light in industrial areas or workspaces, and mechanically hold and electrically connect lamp bulbs to wiring.
LED Lamps (144 Companies)
Solid-state lamps that emit visible light when forward biased. By far the most popular type of illuminating device in industrial use today and are replacing traditional lamps.
Light Pipes (20 Companies)
Rigid, or flexible, tubes or “pipes” that transport light from a source to a viewing surface. With rigid design, light pipes may be in the shape of a PC; for flexible design, optical fiber is commonly used.
Magnetic Ballasts (21 Companies)
Magnetic Ballasts limit the amount of current available to circuits. This electrical condition powers fluorescent, neon, and high-intensity discharge lamps.
Neon Lamps (37 Companies)
A Neon Lamp is a gas discharge lamp containing primarily neon gas at low pressure. The term is sometimes used for similar devices filled with other noble gases, usually to produce different colors.
Stroboscopic Lamps, or strobe lights, produce regular, pulsed flashes of light, used in lighting and alarm systems. A Xenon flash lamp is an electric glow discharge light. It produces very intense and full-spectrum white light for short periods of time
Surface Mount LED Lamps (51 Companies)
LED Lamps are often directly mounted to a PCB (printed circuit board). The lamp uses conserved power to emit electrical energy.
Tungsten Halogen Lamps (31 Companies)
An incandescent lamp in which a tungsten filament is sealed into a compact transparent envelope filled with an inert gas, plus a small amount of halogen such as iodine or bromine. Their small size makes them advantageous for use in optical systems.
Ultraviolet Lamps (36 Companies)
Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays. The spectrum consists of electromagnetic waves with violet frequencies beyond human visibility.
