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.
