Abstract

The utility model discloses a LED grading structure, it includes the LED light source of fixing on the base plate, the lamp shade that sets up LED light source department to and the lens of setting on the LED light source goes out the plain noodles, wherein the lamp shade is equipped with in cooperation department with lens has paraboloidal reflection of light face. Realize the secondary grading of LED light -emitting through setting up lens, the partial direct irradiation of light behind the secondary grading is gone out, and the reflection of light face reecho that the part is shone on the lamp shade is gone out, has reduced the loss of light effectively, has improved the utilization ratio of light, and the utility model discloses simple structure, nimble practical, adopt the accurate light distribution curve and the optical optimal design of secondary of lens of reflection of light face, accurate control light direction, distribute the region of required illumination to light on, improve and export the light efficiency and the degree of consistency, prevent light pollution and glare.

Description

A kind of LED light distribution structure

Technical field

The utility model relates to a kind of LED light device, refers to a kind of LED light distribution structure especially.

Background technology

Traditional light distributing method roughly has three kinds, and one is that light source directly adds lens luminous intensity distribution, and this kind of method dazzle is serious; Another kind is that light source adds PC cover or cloche, and this kind of method is without secondary light-distribution; Also have one to be add PC cover or cloche after light source adds lens again, this kind of method dazzle is serious, and light efficiency is not high.

Utility model content

The purpose of this utility model be to provide a kind of can effectively improve export light efficiency and all degree of friendship, prevent the LED light distribution structure of light pollution and dazzle.

For achieving the above object, solution of the present utility model is:

A kind of LED light distribution structure, it comprises the LED light source be fixed on substrate, arranges the lampshade at LED light source place, and is arranged on the lens on LED light source exiting surface; Wherein: described lampshade is provided with in the cooperation place with lens has paraboloidal reflective surface.

Described lens are fixed on substrate by silica gel ring.

After adopting such scheme, the utility model realizes the secondary light-distribution of LED bright dipping by arranging lens, the light part direct irradiation after secondary light-distribution is gone out, and partial illumination reflects away to the reflective surface on lampshade again, significantly reduce the loss of light, improve the utilization rate of light; And the utility model structure is simple, flexible practicality, adopts the optimal design of the accurate distribution curve flux of reflective surface and the secondary optics of lens, accurately controls radiation direction, light is assigned on the region of required illumination, improves output light efficiency and the uniformity, prevent light pollution and dazzle.

Accompanying drawing explanation

Fig. 1 is structure top view of the present utility model;

Fig. 2 is structure sectional view of the present utility model.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1, 2, the utility model discloses a kind of LED light distribution structure, and it comprises the LED light source 1 be fixed on substrate A, the lampshade 2 arranged on LED light source 1, and is arranged on the lens 3 on LED light source 1 exiting surface;

Key of the present utility model is: described lampshade 2 is provided with in the cooperation place with lens 3 has paraboloidal reflective surface 21.

Lens 3 in this embodiment are fixed on the substrate A of fixed L ED light source by silica gel ring 4.

The utility model realizes the secondary light-distribution of LED bright dipping by arranging lens 3, the light part direct irradiation after secondary light-distribution is gone out, and partial illumination reflects away to the reflective surface 21 on lampshade 2 again, significantly reduces the loss of light, improves the utilization rate of light; And the utility model structure is simple, flexible practicality, adopts the optimal design of the accurate distribution curve flux of reflective surface 21 and the secondary optics of lens 3, accurately controls radiation direction, light is assigned on the region of required illumination, improves output light efficiency and the uniformity, prevent light pollution and dazzle.

The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model to be imposed any restrictions, therefore the change in every case done according to claim of the present utility model and description or modification, all should belong within scope that the utility model patent contains.

Claims

1. a LED light distribution structure, it comprises the LED light source be fixed on substrate, arranges the lampshade at LED light source place, and is arranged on the lens on LED light source exiting surface; It is characterized in that: described lampshade is provided with in the cooperation place with lens has paraboloidal reflective surface.
