Description

Low-glare LED panel lamp

Technical Field

The utility model relates to a LED panel light technical field, in particular to LED panel light of low glare.

Background

The existing LED panel lamp is widely used. However, the LED panel lamp is too bright near the LED lamp strip, and the brightness is not uniform, so that glare is easy to generate. In order to solve the problem, the existing LED panel lamp is generally provided with a grating and the grating is disposed along a direction perpendicular to the back cover plate to form a light guiding space, so that light emitted by the LED lamp beads is linearly disposed, thereby reducing the glare index UGR. However, lateral light is not considered in the grid structure, although the LED light bars and the grid are arranged in the same direction, since the LED light beads on the LED light bars have a certain distance, the distance enables the lateral light to be incident on the grid, and thus the glare index of the whole LED panel lamp does not reach a very low level.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a lower LED panel light of glare index.

The utility model provides a solution of its technical problem is: a low-glare LED panel lamp, comprising: back of the body lid, light emitting source, outline and grid board, the light emitting source includes LED lamp pearl array, LED lamp pearl array is installed on the diapire of back of the body lid, the opening of grid board and back of the body lid passes through the outline lock, the inner wall of the unit grid of grid board is equipped with the recess matrix.

Further, the groove arrays are all longitudinal.

Further, the cross section of the notch array is wedge-shaped.

Further, the LED panel light also comprises a diffusion plate, and the diffusion plate is arranged between the light emitting source and the grating plate.

Further, the luminous source still includes the base plate, LED lamp pearl array welding is in on the base plate, the base plate has the fretwork, the base plate is connected with the diapire that covers with the back of the body through the screw.

Further, the substrate is an aluminum plate.

Furthermore, the grid plate is formed by splicing a plurality of grid modules.

The utility model has the advantages that: the lateral light is reflected through the groove array, and the transmission direction of the lateral light is changed, so that the lateral light is mutually scattered in the groove array, the light is further more uniform, and the very low glare index is achieved.

Detailed Description

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the coupling/connection relationships mentioned herein do not mean that the components are directly connected, but mean that a better coupling structure can be formed by adding or reducing coupling accessories according to specific implementation conditions. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.

Embodiment 1, referring to fig. 1, 2 and 3, a low glare LED panel lamp comprising: back lid 100, light emitting source 200, outline 400 and grid plate 300, back lid 100 is the basin form, and light emitting source 200 includes LED lamp pearl array, and LED lamp pearl array is installed on the diapire of back lid 100, and outline 400 lock is passed through with the opening of back lid 100 to grid plate 300, and the inner wall of the unit grid of grid plate 300 is equipped with groove array 310.

The groove array 310 has grooves uniformly arranged on the inner wall of the cell grating. When the side light 301 is incident to the unit grating, the groove array 310 reflects the side light 301 and changes the transmission direction of the side light 301, so that the side light 301 is mutually scattered in the groove array 310, further making the light more uniform and achieving a very low glare index.

Groove matrix 310 can be oriented in a variety of ways, both transversely and longitudinally. For ease of manufacture, in some embodiments, a longitudinal groove array 310 may be most suitable. In particular, the longitudinal groove array 310 may be formed by pressing. Wherein the cross section of the groove mouth of the groove array 310 is wedge-shaped.

In some embodiments, in order to further reduce the glare index, a diffusion plate 500 is further disposed between the light emitting source 200 and the grating plate 300, and the diffusion plate 500 may further diffuse the light, so that the light distribution curve of the light emitted from the LED panel lamp is closer to the lambertian light source form.

The light emitting sources 200 have various forms, wherein in some embodiments, the LED bead arrays are welded on the hollowed-out substrate 210, and the bottom wall of the back cover 100 is stamped with a pressing buckle, which presses the substrate 210, so that the substrate 210 is installed on the bottom wall of the back cover 100, and the LED bead arrays are integrated into a whole through the substrate 210, thereby facilitating installation. Moreover, the use amount of the material of the substrate 210 can be reduced by using the hollowed-out substrate 210. To the selection of the material of base plate 210, in the preferred embodiment, can choose for use aluminum plate, because the aluminium material has good heat dispersion, adopt the aluminium material as base plate 210 can finely dispel the heat to LED lamp pearl array.

In some embodiments, grid plate 300 is fabricated from a plurality of grid modules. In order to produce the grid plate 300 more cost-effectively, the grid plate 300 is spliced by a plurality of grid modules produced in a standardized manner, which reduces the production cost.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and changes without departing from the spirit of the invention.
