Liang Li De Chen
Mr. Chen: Many people pay attention to illumination. The higher the illumination, the higher the brightness. Is this the case?
Professor Yang: If it is used as indoor function lighting, we can pay attention to illumination. Because the light has a facade illumination on the table, a horizontal illumination, so we can pay attention to the illumination. However, outdoor is not only concerned with illuminance, but also with brightness. When the car is driving on the road, the car has a low beam light that illuminates the ground. The brightness of outdoor lighting is critical. Can you see it 200 meters away? Like this situation, the high pressure sodium lamp does have its drawbacks because it can't be seen at night. At this point, the LED is better than the high pressure sodium lamp. However, LEDs also have a number of disadvantages. It lacks red light, so street lighting emphasizes the use of ceramic metal halide lamps, both dark and bright. In terms of the effect of illumination, the effect of the high-pressure sodium lamp at night is actually a little worse. If it is in the same situation, I use ceramic metal halide lamps. Because ceramic metal halide lamps are more visible than LEDs, dark vision is higher. In general, no one can deny LED. We have to deny that it is not used properly and affirm its merits. This advantage is its absolute advantage, but often its advantages are also disadvantages. Directional lighting is an advantage, but in some cases it is a big weakness. Therefore, we must carry out secondary optical design, three optical design. We cannot emphasize the advantages or disadvantages. It should be to use its advantages just right.
