Separated type aluminum plastic lamp holder

Abstract

The invention relates to a separated type aluminum plastic lamp holder which mainly comprises a base and a lamp tube sheath. The base is provided with lamp tube jacks symmetrical left and right, is connected with the lamp tube sheath in a buckling way, and is made of polybutylece terephthalate (PBT) plastics; the melting temperature of the PBT plastics is 220 to 230 DEG C; a copper pin and a groove are arranged on the bottom part of the base; and the copper pin and the base are fixed in a mould, so that the base structure is effectively stabilized, and heat insulation stress deformation and secondary processing damage are effectively avoided. The lamp tube sheath is made of an aluminum alloy and is connected with a lamp tube; the lamp tube is of a double-tube shape structure; a tungsten filament in the lamp tube is arranged in the lamp tube sheath; the distance between the tungsten filament and a horizontal plane of an upper edge of the lamp tube sheath as well as the distance betweenthe tungsten filament and a horizontal plane of a lower edge of the lamp tube sheath are 0.4 to 0.7 cm; and the distances between two ends of the tungsten filament and the inner wall of the lamp tubesheath are 0.2 to 0.4 cm; and the aluminum alloy lamp tube sheath is beneficial to conducting and radiating heat generated by the lamp filament into air, so that the service life of the lamp tube is effectively prolonged. The separated type aluminum plastic lamp holder is connected with a U-shaped light pipe in a matching way so as to be used, is commonly used for ultraviolet sterilization and disinfection, waste treatment and other environmental protection treatment, and is simple and convenient to use and low in manufacturing cost.

Description

Technical field [0001] The invention relates to a split aluminum-plastic lamp cap, in particular to a lamp cap composed of a base and a lamp tube jacket, and a copper needle is connected to the bottom of the base and integrally formed in a mold. Background technique [0002] Lighting lamps are widely used in our daily life and industrial production. Lighting lamps need to be matched and installed with the lamp holder. At present, there are many types of lamp holders and different performance characteristics and application industries. The present invention provides a split aluminum-plastic lamp holder, which is compatible with The dual-tube lamp is matched and used, mainly including a plastic base and an aluminum alloy lamp jacket, which is used in ultraviolet sterilization, oil fume purification, sewage treatment and exhaust gas treatment, etc.; the current type of lamp holders on the market all use ceramic lamp holders, and the quality of the ceramic itself Heavy, high-power la...
