Embodiment 1

[0034] Embodiment 1 provides a high-power LED lamp, such as figure 1 , figure 2 , image 3 and Figure 4 As shown, it includes a light source substrate 1, an LED light source 2 is mounted on one end of the light source substrate 1, and at least one heat sink 5 is fixedly connected to the other end, and the heat sink 5 includes an outer cylinder wall 51 extending vertically and located on the Inside the outer cylinder wall 51 and connected to a number of heat dissipation fins 52 on the outer cylinder wall 51, the heat dissipation fins 52 are suitable for dividing the heat sink 5 into several heat dissipation channels 53 extending in the vertical direction to dissipate heat. The top of the channel 53 is directly connected with the outside air.

[0035] Specifically, four heat sinks 5 are provided, and the heat sink 5 is formed into a hollow cylinder shape. The side of the light source substrate 1 connected to the heat sink 5 is provided with a boss 8, and the heat sink 5 Th...

Embodiment 2

[0049] This embodiment provides a high-power LED lamp, which differs from Embodiment 1 in that: Figure 5As shown, the heat dissipation fins 52 in the radiator 5 are arranged between the inner cylinder wall 54 and the outer cylinder wall 51, and are only composed of several support fins 52a, and the support fins 52a will dissipate heat The device 5 is divided into several cooling channels 53 extending in the vertical direction, that is, between any adjacent two supporting fins 52a, the inner cylinder wall 54, and the outer cylinder wall 51, a cooling channel 53 is formed in the vertical direction, and the cooling channel 53 The top of the heat dissipation channel 53 is directly connected to the outside air, and the bottom of the heat dissipation channel 53 is connected to the surface of the light source substrate 1 . The number of supporting fins 52a is determined by the power of the LED light source installed on the light source substrate 1. The greater the power of the LED l...

Embodiment 3

[0051] This embodiment provides a high-power LED lamp, which differs from Embodiment 1 in that: Figure 6 As shown, the radiator 5 includes an outer cylinder wall 51 and a plurality of heat dissipation support fins 52a radially connected between the two inner walls of the outer cylinder wall. The screw holes 14 are connected to the light source substrate 1 .

[0052] In this embodiment, the LED driving light source is hung outside the heat sink 5 .

Abstract

The invention belongs to the technical field of photoelectric LED lighting, and relates to a large-power LED lamp. The large-power LED lamp comprises a light source base plate; an LED light source is mounted at one end of a light source base plate, and while the other end of the light source base plate is fixedly connected with at least one radiator; the radiator comprises an outer barrel wall which extends in the vertical direction, and a plurality of radiating fins which are positioned in the outer barrel wall and connected to the outer barrel wall; the radiating fins divide the radiator into a plurality of radiating channels which extend in the vertical direction; the top parts of the radiating channels directly communicate with the outside air. According to the large-power LED lamp, the generated heat is timely transmitted to cold air in the radiating channels through the light source base plate, the cold air is heated and floated to be subjected to convection dissipation with the outside air on the top ends of the radiating channels, then the heat in the radiating channels can be timely radiated, thus the temperature of the light source base plate is reduced, an LED chip can be kept in a relatively low temperature state, and as a result, the service life of the LED chip is prolonged, and the demand of a large place on a large-power lighting device can be met.

Description

technical field [0001] The invention relates to a high-power LED lamp, belonging to the photoelectric technical field of LED lighting. Background technique [0002] The LED light source is a solid-state light source and an electroluminescent light source. It has high luminous efficiency, long service life, energy saving, green environmental protection, low consumption and safety, shockproof and waterproof, small size, light weight, easy dimming, and less maintenance. It has become an ideal substitute product for traditional light sources such as incandescent lamps, fluorescent lamps, high / low pressure sodium lamps, gas discharge lamps, mercury lamps, halogen lamps, etc. . [0003] At present, large sites such as factories, workshops, ports, construction machinery sites, tall buildings, and high-altitude operations need to use high-power or super-power lamps to meet the lighting needs. The lighting power requires 1000W-4000W or 4000W or more. Most of the lamps and lanterns ...
