Description

High light efficiency LED grid down lamp

Technical Field

The utility model relates to an illumination lamps and lanterns technical field especially relates to a high light efficiency LED grid down lamp.

Background

The down lamp is suitable for indoor commercial lighting and office lighting environments, such as offices, shopping malls, supermarkets, hotels, schools, villas and other lighting fields or decoration fields. As shown in fig. 1 and 2, a conventional LED tube light generally includes a light source plate, a reflector, a heat sink, a diffuser plate, a face ring, and a spring clip. The light source plate is fixed on the radiator through screws to form a heat dissipation module, the diffusion plate is fixed on the face ring, the face ring is locked and fixed with the heat dissipation module through screws, and the light source plate is fixed on a ceiling with corresponding mounting holes by utilizing spring clamps.

The existing LED down lamp structure has the following defects: the distance between the diffusion plate and the light source plate is kept about 30mm to ensure that the light emitted by the lamp is uniform, the light emitted by the LED light source is diffused to the inner wall of the lamp body in the space and is greatly lost, and although the reflector is added to reduce the loss of light, the loss of the lamp structure is still as high as at least 30%; in the above, the light is refracted by the diffusion plate, the outgoing light has the characteristic of large angle, after the light is dispersed to a larger space, the illumination of the illuminated area is insufficient, and the relative utilization of the light is low; in addition, the light emitting angle of the lamp is large, the requirement of small-angle illumination is difficult to realize, part of light rays directly enter eyes of people to generate glare, and discomfort of the body is easily caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a high light efficiency LED grid down lamp just in order to solve above-mentioned problem.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

the utility model discloses a grid face ring, lens, light source board, LED light source, back lid and power, the LED light source fix set up in on the light source board, the power with the power input end of LED light source is connected, lens are located on the light source board, and are located LED light source top, the grid face ring is located lens periphery, back lid through back lid fixing bolt with the another side fixed connection of LED panel.

Preferably, the spring clips are fixedly mounted on two sides of the rear cover through spring clip mounting bolts respectively.

As an improvement, the electric wire of the power supply is fixedly connected with the rear cover through a pull-proof buckle.

Preferably, the grid surface ring is provided with a plurality of windows which are distributed in a rectangular array, each window is provided with one lens, and an LED light source is arranged below each lens.

Further, the lens is a honeycomb lens.

The beneficial effects of the utility model reside in that:

the utility model relates to a high light efficiency LED grid down lamp, compared with the prior art, the utility model discloses with the direct and LED light source contact of lens, let all lights that LED sent pass through the light-emitting direction and the angle that the refraction control lamps and lanterns design needs of lens. The diffusion plate of the existing down lamp is replaced by the lens, the LED light-emitting surface is almost not far away from the lens, the light emitted by the LED is completely in the lens, the unnecessary loss of the light in the lamp body is eliminated, and the light-emitting efficiency can reach 90%; the light rays refracted by the convex lenses eliminate redundant stray light when passing through the grating on each convex lens, so that the stray light is prevented from directly irradiating human eyes, the glare of the product can be reduced, and the illumination quality is improved; after the distance between the lens and the light source is cancelled, the height size of the lamp is effectively reduced, and the lamp can be applied to a smaller installation space; the light emitted by the LED light source is refracted through the aspheric surface of the lens, so that the distribution of the light in the space is changed, the utilization rate of the light is improved, and the illuminated object or the illuminated surface has higher illumination under less light flux; has the value of popularization and application.
