Abstract

An LED panel lamp comprises a frame, a substrate, a plurality of blue light LEDs, a light guide plate, a diffusion plate and a film. The light guide plate and the diffusion plate are embedded in the frame. The substrate is arranged on one inner side of the frame, which is opposite to one side of the light guide plate, one side of the substrate, which is opposite to the side of the light guide plate, is provided with a plurality of side-by-side cup sockets, and one blue light LED is mounted in each cup socket. The blue light LEDs are connected in series or in parallel. The film is attached on one side of the light guide plate, which is opposite to the blue light LEDs, the light guide plate is provided with a reflective film, which is attached on one surface of the light guide plate, and the diffusion plate is arranged on one surface of the light guide plate, which is opposite from the reflective film. The emergent light of the LED panel lamp is more uniform, dazzling light cannot be produced, and the influence of the damage of a single LED on the overall light effect is less. The distribution density of the blue light LEDs arranged side by side is lower, so the heat-dissipating effect is better; since the blue light LEDs are directly mounted in the cup sockets, production is simple, and the production cost is reduced.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As depicted in figs. 1 and 2, in one embodiment, a kind of LED panel light comprises lamp door 110, substrate 120, a plurality of blue-ray LED 130, LGP 140, diffuser plate 150 and the film 160 that is doped with fluorescent material.LGP 140 is embedded in lamp door 110 with diffuser plate 150.

Lamp door 110 comprises four

installing plate

112a, 112b, 112c, 112d and four

connector

114a, 114b, 114c, 114d.Four

connector

114a, 114b, 114c, 114d are used for connecting four

installing plate

112a, 112b, 112c, 112d.Each

installing plate

112a, 112b, 112c, 112d have towards the inboard plates that extend of lamp door 110 along 1122, and substrate 120 and/or diffuser plate 150 are carried on plate along 1122.In the present embodiment, have at least an installing plate also to have accepting groove (not indicating) and wiring female seat (not indicating), this accepting groove is used for accommodating the conductor wire that is electrically connected with a plurality of blue-ray LEDs 130, and the both positive and negative polarity of conductor wire is connected with the plug that is complementary with wiring female seat (not indicating).Usually, installing plate has a plurality of reinforcements and a plurality of louvre, to gain in strength and radiating effect.Each connector is L-type, and the two ends of each installing plate have slot (not indicating), and the two ends of connector are inserted in slot respectively and bolt is fixed in installing plate.

Substrate 120 is arranged at the medial surface of the lamp door 110 relative with LGP 140.Substrate 120 adopts aluminum to make.The side that substrate 120 is relative with LGP 140 sides offers a plurality of glasss of grooves 122 side by side, and each glass groove 122 is installed a blue-ray LED 130.In the present embodiment, blue-ray LED is blue-light LED chip, and the side that this blue-light LED chip is relative with the side of LGP 140 is coated with silica gel, with the protection blue-light LED chip.A plurality of blue-ray LEDs 130 are connected in series or are connected in parallel.Film 160 is attached at the side of the LGP 140 relative with a plurality of blue-ray LED 130.LGP 140 has reflective membrane 142, and this reflective membrane 142 is attached at a surface of LGP.Diffuser plate 150 is arranged at a surface with the opposing LGP 140 of reflective membrane 142, and diffuser plate 150 is generally the PC plate, and its effect is that light is disperseed uniformly, is that the light that irradiates is more even.LGP 140 is acrylic board.
