Wide-angle LED (light-emitting diode) lamp

Abstract

The invention discloses a wide-angle LED (light-emitting diode) lamp which comprises a lamp holder, a driving power supply, a first lamp body, a first lamp panel, a first bulb, a second lamp body, a second lamp panel and a second bulb. The driving power supply is electrically connected with the lamp holder, the first lamp panel is arranged on the first lamp body, an LED light source is arranged on the first lamp panel, the second lamp panel is arranged on the second lamp body, another LED light source is arranged on the second lamp panel, the first lamp panel and the second lamp panel are not positioned on the same plane, the first lamp body, the first lamp panel and the first bulb form a first light-emitting section, and the second lamp body, the second lamp panel and the second bulb form a second light-emitting section. The first lamp body and the second lamp body are not positioned on the same plane and are layered, a height difference is formed between the first lamp body and the second lamp body, and heat dissipation is facilitated while the light-emitting angle of the whole LED lamp is increased.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a wide-angle LED lamp. Background technique [0002] It is difficult for ordinary LED bulbs to achieve a wide angle, limited by the shape of the bulb, so the angle basically does not exceed 200°. [0003] The existing wide-angle LED lamp design is generally to set a protruding multi-faceted base on the radiator, and the LED lamp beads are attached to three or more aluminum lamp panels, and then the aluminum lamp panels are attached to the multi-faceted panels. on different side walls of the shaped base. Although this design can increase the angle, it will be poor in heat dissipation, because its heat dissipation cross-sectional area is smaller than that of ordinary LED bulbs; in addition, making multiple aluminum light panels will increase the material cost, and it will also increase the cost during the assembly stage. It will increase the difficulty of assembly, thereby i...

Problems solved by technology

Although this design can make the angle larger, it will be poor in heat dissipation because its heat dissipation cross-sectional area is smaller than that of ordinary LED bulbs; in addition, making multiple aluminum light panels will increase material costs, and it will also increase the cost of materials during the assembly stage. Will increase the difficulty of assembly, thereby increasing labor costs

[0004] There are also some existing wide-angle LED lamp designs that utilize multiple rod-shaped LEDs or multiple strip-shaped substrates to achieve wide angles, but the disadvantages of these designs are poor heat dissipation and complicated processes; Power, difficult to produce, and can not guarantee the life
