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 double-lamp-plate LED illuminating lamp comprises a bottom shell 1, an LED light source 20 installed in the bottom shell 1, a light diffusion plate 3 covered on a light outlet of the bottom shell 1 in a sealing mode, and end covers 4 covered at two ends of the bottom shell 1 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 °. The middle part of the bottom wall 11 is provided with a left mounting plate and a right mounting plate 13 which respectively face the left side and the right side of the bottom wall 11 and extend along the length direction of the lamp shell 1. Have lamp plate contained angle b between mounting panel 13 and the diapire 11, the better angle scope of lamp plate contained angle b is 20 to 40, and wherein optimum angle is 30. Left and right lamp plate 2 along the left and right lamp plate 2 that drain pan 1 length direction extends is attached respectively to left and right mounting panel 13, installs many LED light sources 20 along 2 length direction arrangements of lamp plate on this left and right lamp plate 2, controls on the lamp plate LED light source 20's light-emitting direction L respectively towards the 11 left and right sides of diapire. A light-emitting included angle c is formed between the light-emitting direction L of the LED light source 20 and the bottom wall 11, and the preferred angle range of the light-emitting included angle c is 50 ° to 70 °, wherein the optimal angle is 60 °. 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 emergent angle of the LED light source is fan-shaped, the distances from the light of the LED light source on the left lamp plate and the light of the LED light source on the right lamp plate to the light scattering plate can be equal by adopting the circular-arc light scattering plate, and the brightness on the light scattering 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 loudspeaker column structure towards the light-emitting window, the diapire mid-mounting has left and right two lamp plates towards the diapire left and right sides respectively, and the light-emitting direction of LED light source is towards the diapire left and right sides respectively on the left and right lamp plate, and like this, left and right lateral wall can reflect light to the diffusion sheet with higher efficiency, is close to the lateral wall region to the diffusion sheet and reinforces simultaneously, consequently the utility model discloses even LED light source density is lower, also can keep the even and light-emitting efficiency height of luminance on the diffusion sheet.

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.
