Problems solved by technology

High-power LED lamps have high luminous flux and high power. According to the luminous characteristics of LEDs, about 60-70% of the consumed electric energy is converted into heat, while only 30-40% of the consumed electric energy is converted into light, which leads to the emission of high-power LED lamps. high heat
In order to effectively dissipate heat for high-power LED lamps, the existing method is to use a large-area metal heat-dissipating substrate and heat-dissipating shell. However, this leads to high-power LED lamps not only bulky, but also heavy, and extremely inconvenient to install, especially at high altitudes.
In addition, the existing high-power LED lamps often adopt an integrated design, and the application site is single, which easily leads to a backlog of inventory and increases costs

Embodiment 1

[0038] A kind of high-power LED lamp that present embodiment proposes, such as Figure 1a to Figure 1c As shown, it includes a lamp body 1. The lamp body 1 is composed of a housing 11, a power supply compartment 12, a driving power supply 13 and a luminous body 14. The power supply compartment 12 is arranged at the rear end of the housing 11, and the driving power supply 13 is sealed and arranged in the power supply compartment. 12, the illuminant 14 is arranged in the cavity of the casing 11, the illuminant 14 is formed by three independent light source modules 15 with heat dissipation structure arranged side by side, and the rear end of the power supply compartment 12 is detachably installed with a connection Mounting mechanism 2.

[0039] In this specific embodiment, the power supply compartment 12 is a hollow box-shaped body with open left and right ends. The housing 11 is composed of a front baffle 111 , a left baffle 112 , a right baffle 113 and a cover 114 . The left ba...

Embodiment 2

[0046] The other structures of the high-power LED lamp proposed in this embodiment are the same as those of the high-power LED lamp in Embodiment 1, the only difference is that the structure of the connection and installation mechanism of the two is different, such as Figure 2a and Figure 2b As shown, that is, the connection and installation mechanism 2 in the high-power LED lamp of this embodiment includes a connection body 21 and a mounting bracket 22, both of which are in a U-shaped structure, and the opening of the connection body 21 and the installation bracket 22 The opening of the connecting body 21 is composed of the first transverse connecting plate 211b which is closely sealed and fixedly connected with the rear end surface of the power supply compartment 12, and the first left connecting plate 212b integrally arranged on the left end of the first transverse connecting plate 211b. The first right connecting plate 213b arranged on the right end of the first transver...

Embodiment 3

[0051] A high-power LED lamp proposed in this embodiment has the same structure as the high-power LED lamp in Embodiment 1 or Embodiment 2. Figure 3a and Figure 3bAs shown, the connection and installation mechanism 2 in the high-power LED lamp of this embodiment includes a connection body 21 and a mounting bracket 22. Sealed and fixedly connected, the connecting body 21 has a sealed cavity 211c for placing wires, the rear end surface of the connecting body 21 is provided with an n-shaped vertical groove 212c, the mounting bracket 22 is in an L-shaped structure, and the mounting bracket The front end of the vertical plate 221c of 22 is provided with an n-shaped vertical clamping block 222c for being embedded in the vertical groove 212c, and the vertical clamping block 222c is embedded in the vertical groove 212c in the horizontal seat 223c of the mounting bracket 22 Located directly below the connecting body 21 and fixedly connected to the lower end surface of the connecting...

Abstract

The invention discloses a high-power LED lamp comprising a lamp body; the lamp body is composed of a shell, a power supply cabin, a driving power supply and a light emitting body; the power supply cabin is arranged at the rear end of the shell; the driving power supply is arranged in the power supply cabin in a sealing way; the light emitting body is arranged in a cavity of the shell and is composed of a light source module with a heat radiating structure or is formed by arranging a plurality of independent light source modules with heat radiating structures side by side; and the rear end of the power supply cabin is detachably provided with a connecting and mounting mechanism. The high-power LED lamp has the advantages that the light emitting body is composed of the plurality of light source modules, and each light source module has the independent heat radiating structure, so that the high-power LED lamp is good in heat radiating property and small in size so as to be more convenient to mount; and the lamp body is separated from the connecting and mounting mechanism, so that not only is the high-power LED lamp convenient to mount, but also connecting and mounting mechanisms with different structures can be designed according to different application occasions, and the high-power LED lamp is wide in application range because of serving as a street lamp, a square lamp, a stadium lamp, a project lamp and the like.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a high-power LED lamp. Background technique [0002] The main light sources used in traditional street lamps are metal halide lamps, fluorescent lamps, and sodium lamps. The power of these street lamps is generally between 150W and 400W. The energy consumption is particularly large and the heat dissipation performance is poor, resulting in short service life and low brightness of these street lamps. , Invisibly increased the cost of use, and at the same time affected the normal work of street lights, especially in today's lack of power and energy, it is not suitable to vigorously promote the use. [0003] With the maturity of LED technology in recent years, LED lights are gradually replacing traditional lighting products due to their advantages of high luminous efficiency, low energy consumption, and long life. High-power LED lights have also been widely used as light sources in street lights, squ...
