technical field

The utility model relates to the field of LEDs, in particular to an LED lens.

Background technique

With the continuous development of the industry, breakthroughs in technology, and vigorous promotion of applications, the luminous efficiency of LEDs is also constantly improving, and the price is constantly falling. The emergence of new combined tube cores has also continuously increased the power of a single LED tube (module). Through continuous efforts in research and development by peers, breakthroughs in new optical designs, and development of new lamp types, the situation of single products is expected to be further reversed. The improvement of the control software also makes the use of LED lighting more convenient. These gradual changes all reflect the broad prospects of LED light-emitting diodes in lighting applications.

LED lens is an optical system that is closely connected with LED to enhance light use efficiency and luminous efficiency, and different lenses can be used to change the light field distribution of LED according to different effects.

The illumination distance of LED lights is generally relatively short, and generally needs to be used with multiple LED lights and LED lenses. However, the current LED lenses have poor light gathering ability, small range improvement, and general effect.
