Technical Field
The utility model relates to a lamps and lanterns especially relate to a many lamp panels LED illumination lamps and lanterns.
Background
A conventional LED lighting fixture structure is shown in fig. 1. The bottom shell 1 comprises a rectangular bottom shell 1, wherein the bottom shell 1 comprises a bottom plate 1 and side plates 12 which are positioned on two sides of the bottom shell 1 and are perpendicular to a bottom wall 11. The bottom wall 11 is provided with a lamp panel 2, the lamp panel 2 is provided with a plurality of LED light sources 20, and the light outlet of the bottom shell 1 is covered with a flat light-diffusing plate 3 in a sealing manner. Because the side plate 12 is perpendicular to the bottom plate 1, the light emitting direction of the LED light source 20 is parallel to the side plate 12, the side plate 12 cannot efficiently reflect light rays to the light-diffusing plate 3, and the light emitting efficiency of the lamp is low; further, when the density of the LED light sources 20 is low, the point light sources are easily observed from the outside of the light-diffusing plate 3, and dark regions are easily left in the area of the light-diffusing plate 3 near the side wall 12, resulting in uneven brightness on the light-diffusing plate.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides a two lamp plate LED illumination lamps and lanterns that luminance is even, light-emitting efficiency is high.
The utility model provides a technical means that its technical problem adopted is: the utility model provides a many lamp panels LED illumination lamps and lanterns, includes the drain pan, installs the lamp plate in the drain pan, installs the LED light source on the lamp plate, and scattered light board and the end cover of closing cap at the drain pan both ends of closing cap on the drain pan light-emitting window, the drain pan includes the diapire and connects in the left and right lateral wall of diapire left and right sides, left and right lateral wall and diapire slope setting, left and right lateral wall constitute the horn column structure towards the light-emitting window, and many lamp plates are the circular-arc range of circular arc lateral surface orientation scattered light board in the drain pan.
The utility model has the advantages that: because left and right lateral wall constitutes the horn-shaped structure towards the light-emitting window, installs many lamp plates that become the arcuation range on the diapire, and LED light source on many lamp plates can superpose more even facula on the diffusion sheet, controls the lateral wall and can reflect light to the diffusion sheet more efficiently, is close to the lateral wall region to the diffusion sheet and reinforces simultaneously, even LED light source density is lower, the utility model discloses also can keep the light on the diffusion sheet even with the luminous efficacy height.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and examples. The left and right directional descriptions of the present invention only show the relative position of the components shown in the drawings, and should not be interpreted as an absolute limitation to the scope of the present invention.
Refer to fig. 2 and 3. A multi-lamp-panel LED illuminating lamp comprises a bottom case 1, an LED light source 20 installed in the bottom case 1, a light diffusion plate 3 covered on a light outlet of the bottom case 1 in a sealing mode and end covers 4 covered at two ends of the bottom case in a sealing mode. The bottom shell 1 is formed by cutting a section bar and comprises a bottom wall 11 and left and right side walls 12 connected to the left and right sides of the bottom wall 11. The left and right side walls 12 and the bottom wall 1 are obliquely arranged, and the left and right side walls 12 form a horn-shaped structure facing the light outlet. The left and right side walls 12 and the bottom wall 11 have a bottom wall angle a therebetween, and the bottom wall angle a preferably ranges from 20 ° to 40 °, wherein the optimal angle is 30 °. Set up the cross section on the diapire 11 and be curved mounting panel 13, the circular arc outside of arc mounting panel 13 is towards diffusion sheet 3, and many lamp plate 2 intervals are installed on diffusion sheet 3's arc lateral surface uniformly, install the LED light source 20 of light-emitting direction L towards diffusion sheet on the lamp plate 2. The number of the lamp panels 2 is more than three, wherein the optimal number is singular. In order to increase the light reflection efficiency, the left and right sidewalls 12 may be coated or attached with light reflection materials, or made of materials having light reflection properties such as aluminum materials or copper materials. The present invention preferably uses aluminum material to make the bottom wall 11 and the side wall 12 as an integral structure.
Refer to fig. 3 to 5. The cross section of the light diffusion plate 3 may be in the form of a circular arc as shown in fig. 3, a flat plate as shown in fig. 4, or an inverted U as shown in fig. 5. Because the light ray emergence angle of the LED light source is fan-shaped, the adoption of the arc-shaped light-diffusing plate can ensure that the distances from the LED light source light rays on the lamp panels to the light-diffusing plate are equal, and the brightness of the light-diffusing plate is more uniform; in addition, the circular-arc light-diffusing plate 3 has smooth surface and no corner to reflect light, thereby further improving the uniformity of light. When the circular-arc-shaped light-diffusing plate 3 is adopted, the light-emitting direction L of the LED light source 20 is orthogonal to the circular-arc surface of the light-diffusing plate 3, so that the light-emitting efficiency is higher.
The utility model discloses because left and right lateral wall constitutes the horn-shaped structure towards the light-emitting window, installs many lamp plates that become the arcuation range on the diapire, and the LED light source on many lamp plates can superpose more even facula on the diffusion sheet, controls the lateral wall and can reflect light to the diffusion sheet more efficiently, is close to the lateral wall region to the diffusion sheet and reinforces simultaneously, even LED light source density is lower, the utility model discloses also can keep the light on the diffusion sheet even with the light-emitting efficiency height.
The above description of the specific embodiments is only the preferred embodiments of the present invention, and does not represent the limitation of the protection contents of the present invention, and any technical solutions that can be obtained by normal reasoning of the ordinary technicians in the spirit of the present invention are the protection scope of the present invention.
