As we all know, the single LED high bay is low power in tri band led grow light track lights led. In order to obtain high-power, multiple parallel, for example, automobile taillights, single high-power LEDs are very expensive.
One drawback is that the “spot”, the white tri band led grow light manufacturing defects in workmanship coupled with the errors of the reflector or lens, likely to cause a yellow circle. The disadvantage or weakness of the current semiconductor lighting in the following two aspects:
1, high prices of high power LED Lights At present, the market price of the 1 watt power white LED is about ten times than the price of traditional light sources.
2, high-power LED applications, light efficiency is low In the commercialization of more than 3 watts power light emitting diode light emitting efficiency is low, lower than the luminous efficiency of more than 100 lumens per watt high intensity discharge lamps, also lower than the rare earth tricolor fluorescent in more than 60 lumens per watt. If we talking about semiconductor lighting energy saving, energy saving, in fact, just set up within the small power range, the current technology and existing efficient light source high-power lighting does not save much power semiconductor light source, but the initial investment costs high. Another problem is the luminous efficiency is low the shift of the input energy into heat energy, tri band led grow light LED cold light source is just the light itself is not burning the body, but the resistance heat generated by the large current in a semiconductor material, or make LED STREET LIGHT produce a higher temperature of track lights led, produced by the semiconductor materials, light emitting diodes is not high temperature, overheating will make life significantly reduce the radiator to increase the volume of the lamps, the semiconductor light source, small size, light weight advantage disappear.
Based on the above analysis can be seen in terms of luminous efficiency and the price level, the semiconductor light sources in the short term really is not easy to enter the field of general lighting to replace conventional light sources. However, in the current state, the development of semiconductor lighting industry and avoid weaknesses in the dominant direction of positive development, promote technological progress and the maturity of the production process, the semiconductor lighting era track lights led to come early.
