As the fourth-generation electric light source, high-power LED is called “green lighting sourceâ€. It has small size, safe low voltage, long life, high electro-optical conversion efficiency, fast response, energy saving and environmental protection. It will replace the traditional one. Incandescent lamps, tungsten halogen lamps and fluorescent lamps have become the next generation of light sources in the 21st century.
High-power LED street lamps do not contain lead, mercury and other pollution elements, and there is no pollution to the environment, and many advantages. The following are the eight basic questions of high-power LEDs in the application industry:
1, led color difference problem The application of a single LED, there is basically no color difference problem, but if a large number of LEDs are put into use together or a light has multiple LEDs at the same time, the color difference problem will be highlighted.
2. LED insulation problem The insulation referred to here refers to the heat-dissipating substrate. For the positive and negative electrodes of the LED, the fundamental problem has not been solved until now, but only the compensation measures are taken. For example, using an aluminum substrate to handle the insulation may be incomprehensible. . A single LED is not insulated, and the effect is not large. There are problems when multiple series are connected.
3, LED anti-pulse problem This problem is still controversial with the manufacturer, it does exist in my practical application, the main reaction is on the cold pulse, that is, at the moment of power-on, a few LEDs break or break at the moment of cold power-on .
4, the problem of LED illumination angle Because the LED lens package of each manufacturer is not the same, even the same illumination angle (nominal angle), the effect is not the same, making the selection of the concentrator difficult to add, still can not be universal.
5, LED potential blinding hidden danger LED lighting point is too concentrated so that the center point brightness is super strong, so it is easy to hurt people's eyes, although some lighting manufacturers in this regard, but due to the lag of regulations, can only be The problem for people.
6, LED fever problem In theory, LED is not very hot, but due to the current immature technology, LED fever is well known.
7, LED efficiency is low (luminosity), the current LED conversion efficiency is too low
8, LED brightness is insufficient, the LED is currently used as a supporting role in the lighting industry, mainly for decoration.
LED Tube light brightness is especially more soft and make it easy for people to accept.Using CREE, wafer chip as light-emitting semiconductor materials, placed in heat dissipation material, then add cooling casing and stable quality of professional power, protect the internal core, and common fluorescent lamp shape almost tubes, can replace ordinary fluorescent lamps and lanterns.
The Common Led tube light are T8.T5 Led tube light. Two sizes are 1 inches and 5/8 inches diameter. The length of the Led tube light are 60cm.90cm.120cm.
add cooling casing and stable quality of professional power, protect the internal core, and common fluorescent lamp shape almost tubes, can replace ordinary fluorescent lamps and lanterns
