Lamp barrel of explosion-proof fluorescent lamp and explosion-proof fluorescent lamp with the same

Abstract

The invention discloses a lamp drum of an explosion-proof fluorescent lamp and the explosion-proof fluorescent lamp with the lamp drum. The explosion-proof fluorescent lamp comprises the lamp tube, a lamp tube fixing support, a ballast and the lamp drum, wherein the lamp tube fixing support is used for fixing the lamp tube. The lamp drum comprises a transparent lamp cover and a radiator which are connected up and down. A hollow cavity used for placing the lamp tube and the electronic ballast is formed by the transparent lamp cover and the radiator in an enclosing mode. Two ends of the hollow cavity are opened. The transparent lamp cover is made of poly carbonate (PC) materials, and the radiator is made of aluminum materials. The lamp drum is designed to be of a structure that the transparent lamp cover made of the PC materials and the radiator made of the aluminum materials are buckled together, the joint of the lamp cover and the radiator are sealed by pouring glue, and therefore the lamp drum is enabled to simultaneously meet requirements of optics, anti-explosion and heat dissipation of lamps. Accordingly, stability and applicability of products are greatly improved, and market competitiveness of the kind of explosion-proof lamps is enhanced.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a heat dissipation structure of a lamp tube of a fluorescent lamp. Background technique [0002] In the field of explosion-proof lighting, such as offshore platforms, petrochemical plant areas, oil depots and other special places, fluorescent lamps are often used as light sources for lighting. Since the shape of the elongated fluorescent lamp determines the shape and structure of the overall lamp, at present most of the lamp housings of the light-emitting part of the explosion-proof fluorescent lamp are mostly made of plastic materials (commonly used polycarbonate) to make a transparent lamp tube, but this structure can guarantee Optical requirements, but the overall heat dissipation effect of the lamp is very poor, and the greater the power of the fluorescent lamp, the higher the temperature inside the lamp, sometimes even causing damage to the internal electronic ballast.

Since the shape of the elongated fluorescent lamp determines the shape and structure of the overall lamp, at present most of the lamp housings of the light-emitting part of the explosion-proof fluorescent lamp are mostly made of plastic materials (commonly used polycarbonate) to make a transparent lamp tube, but this structure can guarantee Optical requirements, but the overall heat dissipation effect of the lamp is very poor, and the greater the power of the fluorescent lamp, the higher the temperature inside the lamp, sometimes even causing damage to the internal electronic ballast

[0003] The main reason for the poor heat dissipation effect of the transparent plastic lamp tube as the optical shell is that the heat generated by the electronic ballast, the main heating component in the lamp, is transferred to the transparent lamp tube by thermal radiation and heat conduction, and then conducted by the transparent lamp tube. To the outside of the lamp, the thermal conductivity of air is only 0.023W / (m*K), and the thermal conductivity of polycarbonate is 0.16-0.2 W / (m*K), so it is difficult for such a lamp tube heat dissipation structure to meet the current requirements.
