LED STREET LIGHT (supernova led grow light review) is a field light source, its light-emitting principle is a PN junction with a positive voltage at both ends of Hole in the P region to the N region. As the minority carrier and majority carrier compound to release energy, part of the energy into heat, the other part of the energy into light.
LED Lights (supernova led grow light review) luminous color in the matrix and the infiltration of miscellaneous materials, in addition to white light are basically pure monochromatic light, light color, easy to control, it can be widely used in traffic lights, hand signal lamp display screen and so on. Traditional railway handheld lights ordinary incandescent bulbs or inflatable incandescent light bulbs as a light source, a red signal, green signal, the yellow signal generated by the red, green, yellow polycarbonate filter, on the one hand, in the polycarbonate added to the molding process, the toner amount is difficult to accurately control, leading to the resulting color is not pure, on the other hand polycarbonate in the long-term use, in particular, will degrade in sunlight yellow, affect the color displayed. And incandescent bulbs are only a dozen hours of service life, change frequently, continuous working time of more than 10 hours not required, the lighting is also heavier to carry the inconvenience.
There are many manufacturers to use red, green, yellow LED signal light, but also there are some manufacturers use multiple ultra bright white LED as white light white light, however due to the low luminous efficiency, low power, enough illumination therefore only be used as a signal can not play the role of task lighting.
LED light (supernova led grow light review) efficiency with incandescent similar, and increase the scope of the change in color, it has become the basis of the signal light source, while its short response time, low fever, low energy consumption and long life, maintenance costs and low advantage, immediately causes the LED signal lights have a wide range of applications. With the continuous improvement of the optical design, LED luminous efficiency will continue to improve, the number of signal lights use LED tube now down to 100 pieces from the beginning of the four or five hundred, or even dozens of stars.
