When the existing straight light-emitting panel lamp is opened to form mixed light by the double-color lamp beads, spots can appear on the light guide plate due to uneven light mixing, and then the light uniformity of the straight light-emitting panel lamp is influenced, and the appearance is attractive.

As shown in fig. 1, in order to solve the above problem, the present embodiment provides a two-color direct-lighting panel lamp with uniform lighting, which mainly includes a fixing frame 10, a light source group 20, a bottom case 30, and a diffusion plate 40; the bottom shell 30 and the diffusion plate 40 are detachably connected with the symmetrical end surfaces of the fixing frame 10 respectively; the number of the light source groups 20 is several, and any one light source group 20 comprises at least two color light sources which are adjacently arranged; the light source groups 20 are uniformly distributed on the bottom case 30 and are disposed toward the diffusion plate 40.

In the present embodiment, the light source group 20 formed by a plurality of adjacently disposed color light source groups 20 is used as a unit of single arrangement and distribution, so that when the monochromatic light is lit, light sources are formed at all positions on the light guide plate, that is, no visible spots appear on the light guide plate, and the uniform coverage of the illumination area by the light rays when the monochromatic light is lit is ensured; when the mixed light is lighted, the light sources with multiple colors in any light source group 20 are mixed, and the light source group 20 is ensured to be uniformly distributed, so that no visible spots can appear on the light guide plate when the mixed light is lighted.

More specifically, the light source group 20 is distributed on the edge of the bottom shell 30; the light source group 20 is distributed in the center of the bottom case 30 in rows and columns, wherein the light source group 20 is preferably a first light source 11 and a second light source 12 which are adjacently arranged.

In this embodiment, along the light source group 20 that the font distributes is returned along drain pan 30 border, can guarantee that the corner of drain pan 30 is in under the condition of monochromatic light or mixed light, can realize evenly giving out light, and there is not the condition that light is difficult to cover, and set up the light source group 20 that arranges in rows and columns at the center of drain pan 30, then because central area does not shelter from, arrange in rows and columns and satisfy the drain pan 30 center and evenly cover under the prerequisite of light, the quantity of minimize light source group 20 reduces the manufacturing cost of panel lamp.

More specifically, in the light source groups 20 arranged in a zigzag manner, the distances between the first light source 11 and the second light source 12 of any one of the light source groups 20 and the edge of the bottom case 30 are equal.

In this embodiment, in order to realize that the distances between the first light source 11, the second light source 12 and the edge of the back plate are equal, the light source group 20 located at different edges of the square-shaped shape may be arranged in parallel with the closest edge, that is, when the light source group 20 is close to the horizontal edge, the first light source 11 group 20 and the second light source 12 group 20 are horizontally and adjacently arranged, and when the light source group 20 is close to the numerical edge, the first light source 11 group 20 and the second light source 12 group 20 are vertically and adjacently arranged.

More specifically, the light source group 20 arranged in a zigzag shape along the edge of the bottom chassis 30 is composed of the first light source 11 and the second light source 12 arranged in an inclined manner at the corners; the rest of the light source groups 20 arranged in a zigzag shape along the edge of the bottom case 30 are composed of the first light source 11 and the second light source 12 which are adjacent and horizontally arranged, and are composed of the first light source 11 and the second light source 12 which are adjacent and vertically arranged; the light source group 20 disposed in the center of the bottom chassis 30 is preferably composed of the first light source 11 and the second light source 12 disposed adjacently and horizontally.

In this embodiment, the corners of the bottom casing 30 are mainly formed by two adjacent sides forming a 90 ° included angle, so as to ensure that the distance between the first light source 11 and the second light source 12 and the edge of the back plate is equal to the aforementioned distance, the first light source 11 and the second light source 12 can be obliquely disposed, and the distance between the obliquely disposed first light source 11 and the horizontal side is equal to the distance between the second light source 12 and the vertical side, so as to ensure the uniformity of light emission.

In the present embodiment, the light source group 20 disposed in a row and a column at the center of the bottom case 30 is composed of the first light source 11 and the second light source 12 disposed vertically and adjacently, or the first light source 11 and the second light source 12 disposed horizontally and adjacently, and in the lighting state, the luminance is the same, and in the production, the first light source 11 and the second light source 12 can be fixed in the vertical or horizontal direction according to actual conditions.

More specifically, the straight lines of the first light source 11 and the second light source 12, which are obliquely arranged, form an included angle with the adjacent side of the bottom case 30, and the included angle is 45 °.
