Abstract

The invention relates to a high-power LED optical fiber coupling system, and belongs to the technical field of LED light sources. One side of an LED chip in the high-power LED optical fiber coupling system is fixed on an LED heat dissipation bottom plate, so that heat generated during the working of the LED chip can be rapidly transmitted to the LED heat dissipation bottom plate; the other side ofthe LED chip abuts against an incident surface of a first lens, most of optical fibers emitted by the LED chip can be converged by the first lens, so that an utilization rate of LED light beams is improved; the second lens is used for making light beams converged by the first lens become parallel light beams to be emitted out; the third lens is used for focusing the parallel light beams emitted by the second lens and transmitting light rays to the inside of an optical fiber bundle; and the high-power LED optical fiber coupling system is reasonable in structure, high in light utilization efficiency and suitable for popularization and application.

Description

technical field [0001] The invention relates to a high-power LED optical fiber coupling system, belonging to the technical field of LED light sources. Background technique [0002] 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. [0003] LED lighting is gradually expanding to the high-power field. In some special application scenarios, it is necessary to manually control the lighting area of ​​the beam. However, high-power light sources usually require a larger power supply and cooling system,...
