    The advent of LED light source of the earliest applications using the semiconductor PN junction light-emitting principle is made in the early 1960s. The material is GaAsP, red light-emitting (p = 650nm). When at a drive current of 20mA, the luminous flux is only a few thousandths of lumens, and the luminous efficiency is about 0.1 lumens / watt. In the mid 1970s, the elements of In and N is introduced into the manufacturing of LED lights, making the LED produces green, yellow and orange light, the light efficiency is also increased to 1 lumen / watt. At the beginning of the 1980s, there has been GaAlAs LED light source, making the red LED light efficiency become 10 lumens / watt. And in early 1990s, the successful development of the two new materials of red and yellow light GaAlInP and greenish blue GaInN has been greatly improved the LED luminous efficiency.

    The LED instrument panel lights are also known as LED indicator lights. And they are mainly used for automotive lighting, mechanical signals, electrical instrument panel, playing the instructions role, something light signal and the abnormal situation of alarm. Common LED dash light has LED signal meter lights, LED instrument lights and LED safety indicator. The use of one or more pieces of LED light-emitting diode, LED dash light combines with the specific requirements of customers, and design different size and brightness of the LED dashboard lights. LED indicating instrument lights have super bright, and use LED as the light source, which is energy saving, no heat and has long life, and it has the bright color, pure color, red, green, blue, yellow, white and warm white, so colorful! All the color can be customized according to customer requirements.

    LED light tubes are also commonly known as light tubes and fluorescent tube. Its light source uses LED as the luminous body. As we all know, the traditional fluorescent tube is also known as fluorescent lamps, and there is a filament lamp at each end of the lights, filling with traces of argon and thin mercury vapor, the tube wall is coated with phosphor emits ultraviolet light, when the gas conductivity happens between the two filament, the phosphor emit visible light. On the other hand, the LED light tubes use the light-emitting diodes as a light source, has high light-efficient, more energy-efficient, longer service life, and more environmentally friendly properties. It has become the ideal product to replace the present fluorescent tubes.
