A modular LED floodlight with multi-channel output combined arm

Abstract

The invention relates to the field of LED (light-emitting diode) lamps, in particular to a multichannel output combined supporting arm modular LED floodlight. The multichannel output combined supporting arm modular LED floodlight comprises a lamp holder and a power shell, a power module is arranged in the power shell, supporting arm modules which are used for fixing a light source module are arranged at both sides of the light source module, both ends of the supporting arm modules are respectively connected with the power module and the lamp holder, the light source module comprises more than one light modules, the light modules are connected with one another through the supporting arm modules, each supporting arm module comprises a left supporting arm and a right supporting arm which are correspondingly arranged at both sides of one light module, mounting shafts are arranged at both sides of each light module, mounting shaft bases which are matched with the mounting shafts and used for rotating the light modules are arranged on the inner sides of the supporting arms, and the neighboring left supporting arms or right supporting arms are connected movably. The service life of the whole lamp is prolonged, the maintenance cost is reduced, the usage of fixing devices is reduced, the material cost is effectively reduced, the production cost is reduced, the production process is simplified, the usage of fixtures is reduced, and the die cost is reduced.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to a modular LED floodlight with multiple output arms. Background technique [0002] LED downlights, also known as spotlights or projection lights, are mainly lamps that make the illuminance on the designated illuminated surface higher than that of the surrounding environment. The LED used in the LED floodlight is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, the LED floodlight will become the best choice for energy-saving renovation of lighting fixtures in outdoor places. . [0003] At present, the traditional LED floodlights usually use a single output, and use a single plastic module lens or an aluminum reflector for light distribution. The whole lamp adopts an integral design. This design has the following disadvantages: [0004] First of all, the use ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a modular LED floodlight with multi-channel output arms to solve the problem of damage to one LED light source in the overall design of the prior art. It is very cumbersome to disassemble and repair the whole lamp. For lamps, it is necessary to design different sizes of power shells to match, resulting in an increase in production costs and an additional load on the cooling system, which is not conducive to heat dissipation. The luminous projection of lamps can only be concentrated on one surface of the illuminated object
