Comparative advantages of LED flat lights and traditional light sources

LED flat panel lights are playing a huge advantage in the context of energy saving and environmental protection, Yimei believes that it has become a leader in a new generation of lighting products. Global energy shortage is becoming a growing concern, energy saving and environmental protection is becoming more and more important, in this context, the emergence of LED flat light has become very necessary. It has more obvious advantages than traditional light source lamps. LED flat light is a kind of lighting source lamps, compared with traditional light sources, it has more advantages, but also more development potential: First, LED flat light source does not contain harmful metal mercury, unlike high-pressure sodium lamps or metal halide lamps when scrapped to cause harm to the environment. Second, LED flat light can achieve a more perfect dimming function. Since the working range of the LED flat lamp is large, its light output is proportional to the working current, so the method of reducing the current can be dimmed. In addition, due to the frequent switching of the LED flat light without much damage to it, the dimming of the LED flat light can also be obtained by using the method of pulse width adjustment, and the luminous intensity of the LED flat light can be effectively adjusted by adjusting the duty cycle and working frequency of the voltage. Third, Yimei believes that LED flat lamp is a semiconductor bipolar lighting product, and its life is very long. When the luminous flux decays to 80%, its lifetime reaches 25,000 hours. The life of the metal halide lamp is 6000~12000 hours, and the life of the high-pressure sodium lamp is 12000 hours. Fourth, the light color of LED flat lamp is better than that of high-pressure sodium lamp. At the intermediate visual level, the human eye can distinguish things more easily in a high color temperature environment than a low color temperature environment. The color rendering of the LED flat lamp is also much better than that of the high-pressure sodium lamp, and the color rendering index of the high-pressure sodium lamp is only 20 right-left, while the LED flat lamp can reach 65 to 80. Fifth, the basic structure of the LED flat lamp is a piece of electroluminescent semiconductor material, placed on a shelf with a lead, and then sealed around with epoxy resin to protect the internal core wire, so the LED flat lamp has good seismic performance. Finally, in the optical system of the luminaires, the luminous flux loss of the LED flat light source is minimal. Unlike traditional light sources, LED flat lights are half-space light sources. High-pressure sodium lamps or metal halide lamps are full-space light sources that need to change the direction of the outgoing light from one half of the space by 180° to the other half of the space. When we rely on the reflector to accomplish this, the absorption of light by the reflector and the blocking of the light source itself are inevitable. The use of LED flat lamp as a light source, there will be no loss in this respect, the utilization rate of light is higher than the traditional light source.
