[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-Figure 3As shown, the utility model provides the following technical solutions: a LED flat panel lamp without a light guide plate includes a shell 1, a light strip 3, a panel 10 and a connecting piece, the connecting piece includes a shaft body 7, the shaft body 7 is symmetrically installed at an equal interval on the bottom of the inner wall of the shell 1, the panel 10 is arranged inside the shell 1 and is located above the shaft body 7, the light strip 3 is pasted on the shaft body 7, the connecting piece is used to control the change of the angle between the light strip 3 and the panel 10, the connecting piece also includes a rotating groove 12, a protrusion 13 and a protruding tooth 4, a rotating groove 12 is opened at the bottom of the inner wall of the shell 1, and protrusions 13 are symmetrically installed at both ends of the inner wall of the rotating groove 12 at equal intervals, the shaft body 7 is arranged inside the rotating groove 12, and protruding teeth 4 are symmetrically installed on both sides of the surface of the shaft body 7 and relative to the position of the protrusion 13 at equal intervals, the protruding teeth 4 are engaged and connected with the protrusion 13, and the upper parts of the two sides of the inner wall of the shell 1 are symmetrically installed with latch teeth 8 at equal intervals, and the panel 10 is engaged between the latch teeth 8, and the protrusion 13 and the protruding tooth 4 are both plastic structures.
[0019] Through the above technical scheme: during production, the light strip 3 can be pasted on the shaft 7, and then the shaft 7 can be turned to force the light strip 3 to rotate synchronously. Since the protrusion 13 and the protruding teeth 4 are both plastic structures, the protruding teeth 4 also squeeze between the protrusions 13 while the shaft 7 rotates. After the light strip 3 moves to a predetermined angle, the turning is stopped, and the shaft 7 is fixed by the engagement connection of the protruding teeth 4 and the protruding teeth 13, thereby adjusting and optimizing the angle between the light strip 3 and the panel 10, so as to achieve uniform illumination of light and ensure the normal use of the LED flat panel light. This solves the problem of light changes caused by aging of the light guide plate after long-term operation of the current LED flat panel light. In addition, since the panel 10 is embedded between the latch teeth 8, the panel 10 can be pressed down to squeeze the latch teeth 8 and move downward, thereby adjusting the distance between the panel 10 and the light strip 3, thereby cooperating with the shaft 7 to achieve the purpose of uniform illumination of light.
[0020] See also Figure 1-Figure 3 As shown, the surface of the shaft 7 and located above the light strip 3 is covered with a divergent lens 9, and the bottom of the two sides of the divergent lens 9 are symmetrically installed with plug rods 14. The surface of the shaft 7 and located on both sides of the light strip 3 are symmetrically opened with embedding holes 2 at equal intervals. The plug rods 14 are embedded in the embedding holes 2. The outer wall of the plug rod 14 is fixedly attached with a rubber sleeve 11, and the outer wall of the rubber sleeve 11 is in contact with the inner wall of the embedding hole 2. The inner wall of the shell 1 and the side of the shaft 7 are symmetrically installed with embedding strips 5. The surface of the embedding strip 5 is an inclined surface, and a reflector 6 is embedded on the surface of the embedding strip 5, and the reflector 6 is flush with the light strip 3.
[0021] Through the above technical scheme: during installation, multiple divergent lenses 9 are sequentially covered and fixed on the light bulb of the light strip 3, and the rubber sleeve 11 is in contact with the inner wall of the embedding hole 2 through the insertion rod 14 and the embedding hole 2, and the insertion rod 14 is fixed in the embedding hole 2 by friction. During operation, the light generated by the light bulb is diffused by the divergent lenses 9, and the angle of the shaft 7 is adjusted to achieve the purpose of improving the uniform illumination of the LED flat panel light. In addition, during operation, the horizontally divergent light is reflected on the periphery of the panel 10 through the reflectors 6 arranged obliquely on both sides, thereby reducing the problem of dark light around the panel 10.
