Embodiment Construction

[0020] Such as Figures 1 to 10 As shown, the panel light includes an annular panel 1, a cover plate 2, and a ring body 3 sandwiched between the annular panel 1 and the cover plate 2. The ring body 3 and the annular panel 1 are coaxial, and the ring body 3 and the annular panel 1 are integrated. Formed integrated structure, the inner diameter of the ring body 3 is larger than the inner diameter of the annular panel 1, the outer diameter of the ring body 3 is smaller than the outer diameter of the annular panel 1, the ring body 3 and the cover plate 2 are fixedly connected by screws, and the ring body 3 faces the cover plate 2 One side of the ring body 3 is provided with two connecting ears 31, the inside of the ring body 3 is provided with a light bar 4 surrounding the inner wall of the ring body 3, the inside of the ring body 3 is provided with a reflector 5, a light guide plate 6 and a diffusion plate 7, and the cover plate 2. Reflective plate 5, light guide plate 6, diffuse...

Abstract

The invention provides a panel lamp. The panel lamp comprises an annular panel, a cover plate and a loop. A lamp bar, a reflection plate, a light guide plate and a diffuser plate are arranged in the loop. The lamp bar is located between the circumferential side wall of the light guide plate and the inner wall of the loop. The side, facing the circumferential side wall of the light guide plate, of the lamp bar is provided with a plurality of lamp beads. A reflection cup is arranged between the lamp bar and the light guide plate. The included angle formed between the upper reflection plane of the reflection cup and the plane which is located between the upper reflection plane and the lower reflection plane and is parallel to the bottom face of the annular panel ranges from 0 degree to 45 degrees. The included angle formed between the lower reflection plane of the reflection cup and the plane which is located between the upper reflection plane and the lower reflection plane and is parallel to the bottom face of the annular panel ranges from 60 degrees to 90 degrees. The light rays emitted by the lamp beads on the lamp bar can be reflected for the second time through the reflection plane of the reflection cup and the reflection plate so that the angles of the light rays of the lamp beads can be further adjusted and the light rays can be distributed evenly on the light guide plate, the light reflection and guide effects are good, the emitted light is evener, the light diffusion effect is good, and the dazzling phenomenon of the panel lamp can be solved.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a panel lamp. Background technique [0002] As a kind of lighting fixture, panel light is widely used in hotels, conference rooms, factories or offices, commercial purposes, residential or public facilities, schools and hospitals because of its overall flat shape, its light output is completely flat, and its light angle is wider. Where energy-saving and high color rendering index lighting is required. The existing panel lights also have problems such as glare and poor heat dissipation. Moreover, the existing panel lights are generally installed on walls, ceilings and other substrates by hanging or ceiling-mounted installations. In terms of installation and disassembly, it is very troublesome, and there are problems such as unstable installation after disassembly and reinstallation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pa...
