Background technique

The English name of LED spotlights is Led spotlights, which is a spotlight using light-emitting diodes as a light source. It is the most concerned energy-saving and environmentally friendly product at present. There are more and more lamps made of LEDs as light sources. Among them, the most favorable ones are LED spotlights, because compared to other LED lamps, LED spotlights are cheaper. Traditional spotlights mostly use halogen lamps, which have low luminous efficiency, relatively high power consumption, rising ambient temperature and short service life. LED light sources are far superior to traditional lighting fixtures in terms of lighting principles, energy saving, and environmental protection. Moreover, the unidirectionality of LED light emission forms a perfect support for the light distribution of spotlights.

At present, the secondary optical light distribution lens is used for LED spotlights. The basic function is to control the light output angle and light output efficiency. Now LED spotlights are mostly light distribution structures with lenses and flat reflectors. However, in the case of using a lens, in the process of changing the light path, part of the light will inevitably be wasted due to reflection, absorption, etc., which leads to a low overall light extraction efficiency of the LED spotlight. In addition, the light emitted by the LED light source is directly emitted, the light is dazzling, the anti-glare effect is poor, and it is difficult to obtain a good light distribution. Moreover, the illuminance of the existing LED spotlights is fixed, and cannot provide good illuminance when the external light is strong, and cannot lower the illuminance when the external light is weak, so as to save energy.
