LED( 发光二极管) Light source, its important components for light emitting diode ( 领导) , it is a kind of to electric energy into visible light solid state of semiconductor devices. Compared to common existence of lighting, easy to burn and thermal deposition, droop, such as faults, LED light source is
LED light source is a kind of can convert electric power into visible light solid semiconductor devices, it is an important part of the light emitting diode. Compared with ordinary light, led light source has the advantages of easy burning, heat deposition and light attenuation. It is variable, and can make use of the principle of red, green, blue three primary colors, make a different color combination, flexible application, can match various types of point, line, face, very easy to control. As long as the regulating current, the lamp can adjust at will. Led light source reliable performance, its half-life ( The light output down to half the time of the initial value) About 10000 - 100000 hours. At the same time, its brightness extension empty is very big. Like computer technology, the development of light-emitting diodes (leds) follow Moore's law, its brightness doubles every 18 months. Therefore, the led light source will be the first selection of machine vision systems integrators and equipment manufacturers. Machine vision led light source has a long service life, brightness is adjustable, low temperature, balanced, stable, no flicker, no shadow, brightness and color temperature, etc. Machine vision to meet customers technical requirements of high quality and high precision. However, in the production and application of light emitting diode light source, the need to pay attention to a series of problems, so as to better play its performance advantages, namely, how to realize the high efficiency, high color rendering, improve reliability and reduce the cost. As the solar street light [ 。 jschindo。 com] The development of lighting industry, shandong street lamp factory lighting technicians believe that light beam with higher requirements for led lighting, leds for white light spectral distribution and is similar to sunlight, should pay attention to improve the quality of energy efficiency and light color, should fully consider the visual comfort and humanized lighting. Should carry on the intelligent dimming control, lower power consumption, improve the effect of energy saving, the semiconductor lighting provide people with a real energy saving, environmental protection, health, comfortable lighting environment, and under the condition of the present situation of not constantly develop new application areas.
