Problems solved by technology

Compared with traditional incandescent lamps, LEDs are more resistant to damage, and have gradually become the first choice for explosion-proof lamps. However, the heat dissipation of LEDs has always been a major problem, especially in high-temperature environments such as boilers, LEDs will have serious light attenuation. , affecting its use

Embodiment Construction

[0033] In order to solve the problem that traditional lamps will experience serious light attenuation and affect their use in high-temperature environments such as boilers, a LED explosion-proof lamp with good heat dissipation is proposed.

[0034] see figure 1 , the LED explosion-proof lamp 100 of this embodiment includes a lamp housing 110 , a sealing ring 120 , a transparent cover 130 , a wire lead-in device 140 , a rear cover 150 , an LED light source structure 170 and a driving circuit board 190 .

[0035] Such as figure 2 The lamp housing 110 includes a first open end 114 and a second open end 116 opposite to the first open end 114 , and the first open end 114 is provided with threads. A partition plate 112 is disposed on the inner wall of the lamp housing 110 .

[0036] The transparent cover 130 includes a light ring 131 and a transparent member 133 . Such as image 3 and Figure 4 The light ring 131 is a cylindrical body with openings at both ends, including a th...

Abstract

An LED explosion-proof lamp comprises a lamp housing, a transparent cover and an LED light source structure. The lamp housing is a barrel with a first open end, and a partition board is arranged on the inner wall of the lamp housing. The transparent cover is barrel with one end enclosed and comprises a third open end which is connected with the first open end of the lamp housing, so that the transparent cover and the lamp housing form a light source cavity. The LED light source structure is accommodated in the light source cavity and comprises a mounting board and at least one LED. The mounting board is fixed on the partition board which is attached to the mounting board to form a large-area contact surface. According to the arrangement, the mounting board in the LED light source structure is mounted on the partition board and in large-area contact with the same, so that the LEDs are easier to radiate and the LED explosion-proof lamp can work properly under high temperature condition of a boiler and the like, and light failure and the like caused by high temperature is avoided.

Description

[0001] 【Technical field】 [0002] The invention relates to lighting equipment, in particular to an LED explosion-proof lamp. [0003] 【Background technique】 [0004] Luminaires refer to appliances that can transmit light, distribute and change the light distribution of the light source, including all the parts and components required to fix and protect the light source except the light source, as well as the necessary line accessories for connection to the power supply. Explosion-proof lamps (explosion-proof lamps) are one of many lamps with explosion-proof performance, mainly including explosion-proof explosion-proof lamps, safety explosion-proof lamps, mobile explosion-proof lamps, etc. [0005] In petroleum, chemical and other fields, intense high-temperature and high-pressure reactions are often carried out in boilers, accompanied by a large amount of flammable and explosive gases. In the daily maintenance of the boiler, the lamps and lanterns should meet the characteristi...
