Embodiment 1

[0026] The strong heat dissipation LED explosion-proof lamps and lanterns in this embodiment, such as Figure 1 to Figure 3 As shown, a power supply 7 is placed in the sealed power supply chamber 2, one end of the power supply chamber 2 is connected to the lamp holder 1, and the other end is connected to the radiator 4 through the connection part 3, and the distance between the heat source of the LED light source and the heat source of the power supply is increased through the connection part 3, further separating them. heat source, to prevent heat sources from interfering with each other. The middle part of the heat sink 4 is a solid main body 44, and the periphery of the solid main body 44 is provided with a plurality of heat dissipation fins 41. The LED chip 5 is directly packaged on the top surface 42 of the heat sink 4, and there is no need to set a chip packaging base, and the edge of the top surface 42 is installed. With the lampshade 6, the heat of the LED chip 5 is co...

Embodiment 2

[0030] The strong heat dissipation LED explosion-proof lamps and lanterns in this embodiment, such as Figure 4 to Figure 6 As shown, a power supply 7 is placed in the sealed power supply chamber 2, one end of the power supply chamber 2 is connected to the lamp holder 1, and the other end is connected to the radiator 8 through the connecting part 3, and the distance between the heat source of the LED light source and the heat source of the power supply is increased through the connecting part 3, further separating them. heat source, to prevent heat sources from interfering with each other. The middle part of the heat sink 8 is a hollow structure 83, and the LED chip 5 is directly packaged on the top surface 82 of the heat sink 8 without a chip packaging base. The top surface 82 of the radiator 8 conducts from the top surface 82 to the hollow structure 83 of the radiator 8, and exchanges heat with the surrounding air through the body wall 85 of the radiator 8, and the heat diss...

Embodiment 3

[0034] This embodiment is basically the same as Embodiments 1 and 2, the only difference being: Figure 7 and Figure 8 As shown, the upper end of the radiator 4 or the radiator 8 is close to the bottom of the LED chip 5 and is provided with a heat conduction cavity 9, and the heat conduction cavity 9 is equipped with a heat conduction liquid 10, and the heat conduction cavity 9 arranged close to the bottom surface of the LED chip 5 is equipped with a heat conduction liquid 10, each The heat generated by the LED chip 5 is rapidly conducted in all the heat-conducting liquids 10, and the temperature of each LED chip 5 is balanced, so that the operating temperature of each LED chip 5 is basically the same, which is conducive to the uniform light emission of each LED chip 5, and when the heat-conducting liquid 10 is heated Circular convection is formed in the heat conduction cavity 9, which strengthens the heat exchange capability between the LED chip 5 and the heat sink 4 or 8, a...

Abstract

The invention provides an anti-explosion LED (light emitting diode) lamp with strong heat dissipation performance. The anti-explosion LED lamp comprises a power supply cavity for arranging a power supply, wherein the power supply cavity is a sealed space, one end of the power supply cavity is connected with a lamp cap, and the other end of the power supply cavity is connected with a heat dissipater; LED chips are directly encapsulated on the top surface of the heat dissipater; a lampshade is mounted on the edge of the top surface; an insulation layer, a circuit layer and a protection layer are arranged around the LED chips in sequence; the insulation layer is tightly attached to the top surface of the heat dissipater; the circuit layer is arranged on the insulation layer; the protection layer covers the circuit layer. The LED chips are directly encapsulated on the heat dissipater, so that heat generated by the LED chips is directly transferred to the heat dissipater and is subjected to heat exchange with air through the heat dissipater; a heat dissipation structure is simple, and a chip encapsulation base and a circuit mounting plate are not needed, so that a middle component between the LED chips and the heat dissipater is eliminated, heat dissipation of the heat of the LED chips is facilitated, and the heat dissipation performance is improved.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED explosion-proof lamp with strong heat dissipation capability. Background technique [0002] Dust or combustible gas exists in many industrial production sites. In order to meet the production lighting requirements, the power level of the lighting fixtures used in the production site is usually high. Combustible gas and dust. [0003] Traditional explosion-proof lamps usually add a transparent protective cover outside the ordinary lamps, and set a metal mesh cover outside the protective cover to isolate the lamp from the surrounding environment. However, this solution seriously affects the heat dissipation of the lamp, especially for heat dissipation. The required LED lights, the traditional explosion-proof scheme has a large defect. [0004] At present, the invention patent with the publication number CN101886880 discloses a heat dissipation shell structure of an explosion-proof lam...
