Light emitting diode (LED) bulb

Abstract

The invention provides a light emitting diode (LED) bulb, which comprises a connecting device, a heat radiator, a transparent upper lamp shade and a transparent lower lamp shade, wherein the upper lamp shade is connected with the lower lamp shade through a heat radiation plate, a first LED lamp plate is arranged on the upper surface of the heat radiation plate, a second LED lamp plate is arranged on the lower surface of the heat radiation plate, the heat radiator is arranged between the connecting device and the upper lamp shade, one part of the heat radiator is arranged outside the upper lamp shade, the other part of the heat radiator is arranged inside the upper lamp shade and is connected with the first LED lamp plate, and the middle of the heat radiator is also provided with a cavity used for placing a driving power supply. When the LED bulb is adopted, the heat radiation effect is good, the intensity is high, and the decoration effect is good.

Description

Technical field: [0001] The invention relates to the technical field of lighting, in particular to an LED light bulb with a 360° full-radiation angle. Background technique: [0002] At present, LED bulbs have gradually replaced traditional tungsten bulbs and become the mainstream in the market. The light source of the traditional tungsten filament bulb is projected at 360°. Since the LED lamp board in the LED bulb includes the substrate and the LEDs on the substrate, and because the substrate is opaque, the current LED bulb can only be used for one-way projection. light, the lighting range is limited. [0003] Therefore, there is currently a LED light bulb with a 360° full-radiation angle, which includes a closed transparent lampshade, a radiator is arranged in the lampshade, and the radiator is fixed by a support plate arranged in the lampshade. And the lower surface is equipped with LED light panels. In this way, the LED light board on the upper surface emits projected ...

AI Technical Summary

Problems solved by technology

[0004] First, because the radiator is installed in a closed transparent lampshade, the radiator is isolated from the air outside the bulb, so the heat dissipation effect is poor, and it is difficult to increase the power of the bulb, and because the radiator is fixed by the support plate in the lampshade, the strength Low, if the heat sink is made large, the connection will not be stable, and it will increase the difficulty of making high-power bulbs accordingly

[0005] Second, although there are support plates and radiators that divide the space in the transparent lampshade into upper and lower parts, there is no light separation between the upper and lower parts, that is to say, the LED light board on the upper surface of the radiator and the LED lamp board on the lower surface LED light panels need to be of the same color, single color, can only be used for lighting, and the decorative effect is poor
