Abstract

A secondary light source of an LED is generated by a primary light source of the LED penetrating through orderly-arranged lens groups, so that the space angle light collection and the light emitting field modulation are achieved, the light energy can be collected maximally, the highest light energy collecting rate and light energy transmission are achieved, the light emitting effect of a light field lens is obvious, the illumination of the light field is clear, and the light distance is ideal. The primary light source of the LED is communicated with a power supply drive circuit through a circuit device plate; a liquid phase medium storage part used for cooling is arranged below the primary light source of the LED; the lens groups, the primary light source of the and the liquid phase medium storage part are arranged in a coupler assembly barrel in sequence from the top down; each lens group comprises a reflecting cup surrounding the position of the primary light source of the LED, as well as a light emitting lens, a bowl-shaped parabolic light reflex mirror and a light field lens which are arranged above the reflecting cup; one end of the bowl-shaped parabolic light reflex mirror is fixed above the reflecting cup and connected with the light emitting lens; and the other end of the bowl-shaped parabolic light reflex mirror and the light field lens are fixed between a light field bracket and a light filed lens positioning clamping ring.

Description

technical field [0001] The invention relates to an emitting light field coupler for secondary optics of LEDs, belonging to the field of electronic applications, in particular to optical modulation and spatial angle light collection of LEDs and a secondary light source produced by the emitting light field coupler. Background technique [0002] The huge role of LED lights in energy saving and emission reduction has made the LED industry grow rapidly, and the life of the light source is 70,000 to 100,000 hours. Because the LED light source is a primary light source, and it is a direct type of light, the light range is short and the lighting effect is dim. When the human eye directly sees the LED light point, it is extremely dazzling. The effect on the application of LED. [0003] At the beginning of 2007, the LED industry invented a light source constructed with semiconductor light-emitting diode chips. Its composition and mechanism completely changed the lighting status of li...
