Problems solved by technology

Since the large-angle LED lamp needs to weld the LED chip on the heat dissipation column, in order to increase the brightness of the side of the LED lamp, it is necessary to weld multiple LED chips on each side of the bracket, which makes the structure of the LED lamp more complicated and increases The cost of the light source, and a bracket and multiple LED chips are required to achieve all-round and large-angle lighting

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] figure 1 It is an exploded view of the large-angle LED lamp 100 of the present invention. The large-angle LED lamp 100 includes a lamp body 10 , three light source boards 20 and a bulb shell 30 . The bulb shell 30 is covered on the top of the lamp body 10 , and the bottom end of the bulb shell 30 is fixed on the top of the lamp body 10 to house the three light source boards 20 .

[0016] Please refer to figure 1 , the bulb shell 30 is a transparent structure made of plastic or glass. According to consumers' preferences, the light bulb housing 30 can also adopt an opaque structure. The lamp base body 10 includes a conventional lamp base connected to a commercial power supply and a heat dissipation member arranged on the lamp base. The top 12 of the lamp body 10 is a circular planar structure.

Abstract

An LED lamp with a large light emission angle comprises a lamp cap, a bulb shell and a plurality of light source panels. The bulb shell covers the top end of the lamp cap. Each light source panel comprises a substrate and an LED light source arranged on the outer side face of the substrate. The bottom edge of each substrate is fixedly arranged at the top of the lamp cap. An obtuse angle is formed by the outer side face of each substrate and the top of the lamp cap. The substrates are arranged around the axis of the lamp cap by equal angles. The LED lamp with the large light emission angle has the advantages of simple structure and convenience in assembly.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a large-angle light-emitting LED lamp. Background technique [0002] Due to the advantages of energy saving and environmental protection, LED lights are becoming more and more popular. With the advancement of optical technology, the cost has gradually been controlled. However, due to the limitations of the LED packaging structure, the existing LED lights cannot be as comprehensive as incandescent lamps. glow. If you want to make LED lights become the mainstream of the market, you must overcome the problem of small LED light-emitting angles. [0003] The current technology is to set the LED light source on a bracket with a three-dimensional surface, and install the bracket on the top of the lamp head, so that the LED light source is vertically arranged relative to the top surface of the lamp head, so that the light emitted by the LED light source is emitted to the direction around the...
