AI Technical Summary
The existing straight-luminous LED lamps need to be large in the distance between the LED lamp beads and the diffusion plate to reduce the bright spots, resulting in the overall lamp being relatively thick and the light uniformity is insufficient.
Using a double-layer panel structure, the light emitted by the lamp bead plate is first refracted and dispersed by the first light-transmitting panel and under the action of the refractive groove surface, and then secondary scattered through the diffusion panel to form a light-out space to improve the light-out uniformity.
The thickness of the straight luminous lamp is greatly reduced, and the uniformity of light output is improved. The light output is high and there is no light spot.

DETAILED DESCRIPTION
[0017] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0018] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", "top", "bottom", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0019] like Figures 1 and 2As shown, a direct-lighting lamp according to a preferred embodiment of the present invention includes a lamp housing 1, a light-transmitting panel 2 and a lamp bead board 3, wherein the light-transmitting panel 2 is installed on the top surface of the lamp housing 1, the lamp bead board 3 is installed in the lamp groove 11 of the lamp housing 1, and the lamp bead board 3 is opposite to the light-transmitting panel 2, the light-transmitting panel 2 includes a first light-transmitting panel 21 and a second light-transmitting panel 22, at least one of the top surface and the bottom surface of the first light-transmitting panel 21 is provided with a refractive groove surface 211, the second light-transmitting panel 22 is a diffusion panel, the first light-transmitting panel 21 is located between the lamp bead board 3 and the second light-transmitting panel 22, and a light-exiting space is formed between the first light-transmitting panel 21 and the second light-transmitting panel 22.
[0020] The present invention adopts a double-layer panel structure. The light emitted by the lamp bead board 3 first passes through the first light-transmitting panel 21 and is refracted and dispersed under the action of the refraction groove surface 211, and then passes through the diffusion panel for secondary scattering, thereby improving the uniformity of the light output, greatly reducing the thickness of the direct-light lamp, and having high light brightness without the occurrence of bright spots of the light source.

The refractive groove surface 211 is a continuous sawtooth-shaped concave-convex structure. Specifically, the protrusions of the sawtooth-shaped concave-convex structure are right-angled triangles. The sawtooth-shaped concave-convex structure causes more scattering and diffuse reflection of light emitted by the light source, evenly spreading the light emitted by the light source and improving light uniformity. Of course, in other embodiments, the refractive groove surface 211 can be a grid-shaped concave-convex structure.
[0022] Furthermore, the second light-transmitting panel 22 is a frosted panel, which makes the lamp have good light transmittance and makes the emitted light softer.
[0023] Specifically, the distance between the first light-transmitting panel 21 and the second light-transmitting panel 22 is greater than the distance between the first light-transmitting panel 21 and the lamp bead board 3, thereby improving the uniformity of light output.
[0024] Exemplarily, mounting slots 12 are provided on both sides of the top of the lamp housing 1, the light-transmitting panel 2 is an integrated structure, and mounting ridges 23 are provided on the left and right sides of the light-transmitting panel 2 to fit in the mounting slots 12, so as to realize quick installation and fixation of the light-transmitting panel 2.
[0025] Furthermore, mounting grooves 13 for engaging with two sides of the mounting base are respectively provided on both sides of the bottom of the lamp housing 1 , so that the direct-lighting lamp is fixedly mounted through the mounting base.
[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
