What are the power problems of led projection lamps?
At present, many domestic manufacturers of LED projection lamps, perhaps because of lack of laser expertise, often use false reports (higher) laser power to mislead customers intentionally or unintentionally, in order to achieve the purpose of promoting sales. Often the 50mW laser is nominally 100mW, and the 500mW green laser is nominally 1000mW. Assuming there is no laser expertise, experience or measurement, it is indeed difficult to identify the actual power of LED projection lamps. If you have doubts about the actual power of LED projection lamps, the way to do this is to compare two LED projection lamps on-site, or ask for laser advice. experts in the field.
LED projection lights have the advantages of bright colors, high brightness, good directivity, long range, and easy control. Using the non-divergence of the laser beam, it can attract the attention of people as far as a few kilometers away, and the point of announcement from the laser has become the focus of attention. Assuming that the led projection lamp is placed in a building or a mountain top scenic area, the beam is directed into the distance, and a bright green light appears in the air, which is very dazzling. face.
Assuming that it is used outdoors, for example, the laser emitted by the led projection lamp is directed to the water curtain, building or wall, etc., and the laser moves rapidly under the control of the scanning system to form text, images, etc. for appreciation. As for indoor appreciation, for example, led projection lights are installed in theaters, nightclubs, dance halls and other places. Cooperate with a certain amount of dry ice smoke, shoot the laser beam to the smoke and scan it, and also form text, image and animation effects. It can also play a violent laser performance with music, and the bright and bright colors are intoxicating and lingering! Of course, under normal circumstances, led projection lights are used in nightclubs, dance halls, various performances, theaters, outdoor advertising and so on.
