High-heat-dissipation modular LED lamp

Abstract

The invention mainly discloses a high-heat-dissipation modular LED lamp. The high-heat-dissipation modular LED lamp comprises a lamp holder, a lamp shade and led lamp luminaires, wherein the LED lampluminaires are circumferentially distributed on the lamp holder, the led lamp luminaires comprise heat dissipation modules and led light emitting modules, the heat dissipation modules comprise heat dissipation bases, heat dissipation holes are formed in the side surfaces of the heat dissipation bases, and heat dissipation fins with through holes are arranged on the top surfaces of the heat dissipation bases; the led light emitting modules comprise U-shaped lamp brackets rotatably connected above the heat dissipation bases through brackets, led lamp bodies are connected into the U-shaped lamp brackets through limiting brackets, and rotary limiting devices are arranged at one ends of the U-shaped lamp brackets; and a hollow line pipe is arranged in the center of the lamp holder, the lower end of the line pipe is in an opening shape, the upper end of the line pipe protrudes out of the lamp holder and is in a closed shape, threading holes are formed in the positions, corresponding to the heat dissipation bases, of the side surface of the upper end of the line pipe, and lead pipes are arranged between the threading holes and the heat dissipation bases. The high-heat-dissipation modularLED lamp has the functions of good heat dissipation performance, adjustable irradiation range and convenience for daily maintenance.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a modular LED lamp with high heat dissipation. Background technique [0002] The LED lamps in the prior art are especially high-power LED lamps, which generate relatively large heat during operation, so the requirements for heat dissipation and light distribution are relatively high. Most of the existing high-power LED lamps have radiators that are integral Plate type, and the lamp body is fixed. For the radiator of the whole plate structure, the volume is generally large and the cost is high. It needs to be dismantled and repaired as a whole, which not only takes time and effort, but also increases the cost, and also affects the normal operation of the LED lamp; in addition, the fixed lamp body structure will not only cause the light source to be fixed, the irradiation range will be limited, but also form high hot spots, which will easily affect the LED lamp. The normal work,...
