What are the characteristics of LED? Its chip hasvarious structure, packaging and diverse ways, which can be widely used. Light efficiency is in 100 lumens/watt or more, color temperature and color rendering index can be adjusted. Life c

What is LED lights? LED light is a kind of light-emitting diode, which is a solid-state semiconductor devices.It emit light DC added to the PN junction and light depend on electron migration, gallium nitride blue chip is

What are the characteristics of HID xenon lamp? It belongs to the gas discharge lamp light with a higher efficiency about 90 lumens/watt; by changing the metal halide composition to issue different colors of light which also means  regulate co

What is HID xenon lamp? HID xenon lamp inject xenon into the quartz tubewith high-tech, and then improve the 12 volts power instantaneous increase to 23,000 voltsthrough the precision ballast to stimulate the xenon electrons

What are the characteristics of tungsten filament? Because the direct use of tungsten wire heating and heating out of infrared light which most people can not see, so the luminous efficiency is very low in 15 ~ 25 lumens \ tile with high heat. Increas

What is a halogen lamp? Later, people found that the addition of halogen gas can evaporate the tungsten back to the tungsten wire up, andcam also the fast evaporation of tungsten to extend the life, so it is called halogen.

What is tungsten filament? Pull heat resisting tungsten to wire and directly electrify it for heating it to the temperature of above 2600 degrees to a incandescent state, and the incandescent light is directly called the tungst

What is brightness? Brightness (L) is the light intensity of light source (or irradiated surface) in a direction of the unit area.Unit: candela / square meters [cd / m]

What is illumination? Illumination (E) is the ratio between the luminous flux and the area being illuminated. 1lx refers to the illumination that 1lm luminous flux averagely distribute in the area of 1m2 plane.Unit: l

What is the light intensity of the lamp? In general, the light is transmitted in different directions, and the intensity varies. The light emitted by visible light in a particular direction is called light intensity (丨)Unit: Candela [cd]
