Problems solved by technology

Since the light-emitting diode is only installed on one side of the heat sink, the light emitted by it can only radiate outward from this side of the heat sink, so the irradiation range is limited and the lighting effect is not good.

Embodiment Construction

[0013] like figure 1 and figure 2 As shown, the light-emitting diode lamp of the present invention is roughly in the shape of an open book, and includes a lamp frame, two radiators 20 mounted on one side of the lamp frame, two transparent lamp covers 40 mounted on the other side of the lamp frame, and pasted A plurality of LED modules 30 on the heat sink 20 .

[0014] Please also see image 3 and Figure 4 , the light stand includes two fixed frames 10 arranged side by side and a housing 11 located at one side of the fixed frames 10 . Each fixing frame 10 is roughly rectangular and consists of two pairs of side plates 12 , 13 vertically connected end to end. The side plate 13 is a vertical straight body and is longer than the side plate 12 . Each side plate 12 is arc-shaped. Two adjacent side plates 13 of the two fixing frames 10 are parallel and connected to each other so that the two fixing frames 10 form a whole. The two side plates 12 of each fixing frame 10 bend u...

Abstract

The invention relates to an LED lamp, comprising a lamp bracket, two radiators arranged on the two side of the lamp bracket and a plurality of LED modules which are closely arranged on the radiators, wherein, each radiator is integrally formed and is good in heat conductivity. The radiator is provided with an arc-shaped substrate and an elongated mounting plate extending from one side of the substrate. Each substrate has a convex surface and a concave surface facing the convex surface. The two substrates are upwards deviated from each other and extending outwards to form two symmetrical wing parts. The two mounting plates are adjacent and arranged in parallel. A plurality of radiating fins are extending vertically and upwardly from the convex surface of each substrate and the upper surface of the mounting plate and are arranged at equal intervals along the longitudinal direction of the substrate. The central portion of the concave surface of each substrate is transversely divided into a plurality of continuous strip-shaped regions. Each strip-shaped region is designed as an elongated plane. Two adjacent elongated planes are connected with each other at a certain angle. The LED modules are adhered to the elongated planes of the concave surfaces of the arc-shaped substrates.

Description

technical field [0001] The invention relates to a lighting device, in particular to a light emitting diode lamp. Background technique [0002] As a high-efficiency light source, light-emitting diodes have many characteristics such as environmental protection, power saving, and long life, and have been widely used in various fields. [0003] A traditional LED lamp includes a flat radiator and several LED modules installed on one side of the radiator. When the light-emitting diode is turned on, the light-emitting diode module installed on one side of the radiator plays a lighting role. Since the light-emitting diode is only installed on one side of the heat sink, the light emitted by it can only radiate outward from this side of the heat sink, so the irradiation range is limited and the lighting effect is not good. Contents of the invention [0004] In view of this, it is necessary to provide a light-emitting diode lamp with a large irradiating range. [0005] A light-emi...
