Embodiment Construction

[0051] Please refer to the drawings to further explain the present invention.

[0052] Such as figure 1 The structure diagram of the present invention shows a secondary light source of LED. The primary LED light source generates a secondary light source through an orderly arranged lens group to realize spatial angle light gathering and adjust the light field. The LED primary light source passes through a circuit device The board 03 is in conduction with the power drive circuit, and the LED light source chip 01 is fixed on the circuit device board, wherein a liquid-phase medium storage part for cooling is provided under the LED primary light source, the lens group, the LED primary light source and The liquid-phase medium storage part is sequentially arranged in the coupler assembly barrel 10 from top to bottom.

[0053] The coupling assembly barrel 10 is provided with a mounting positioning hole 12 at the bottom, and a light source circuit board positioning and pressing frame 14 is...

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 LED secondary optical light emitting field coupler, which belongs to the electronic application field, in particular to the secondary light source generated by the optical modulation and spatial angle light collection of the LED and the light emitting field coupler. Background technique [0002] The huge role of LED lights in energy saving and emission reduction has led to the rapid growth of the LED industry, with a light source life span of 70,000 to 100,000 hours. Since the LED light source belongs to the primary light source and is a direct light source, the light range is short and the illumination effect is dim. When the human eye sees the LED luminous point, the abnormal glare is dazzling. This is called light effect and glare phenomenon, which hinders The application effect of LED. [0003] In early 2007, the LED industry invented a light source constructed with semiconductor light-emitting diode chips. Its composition and...
