LED modular street lamp holder with adjustable irradiating angle

Abstract

The invention discloses an LED modular street lamp holder with an adjustable irradiating angle, which comprises a lamp holder end cover, LED light source modular components, a side frame, a supportingframe, a lamp holder upper cover, a lamppost pressing board, a connecting rod, a rotating shaft, an LED light source driver, a lamp holder lower cover, an installation pressing board, a lower connecting frame and an upper connecting frame, wherein the lamp holder lower cover is assembled and fixed with the lamp holder upper cover after the LED light source driver, the supporting frame, the rotating shaft and the connecting rod are arranged on the lamp holder upper cover. The LED light source modular components are arranged on the side frame and the upper connecting frame and locked and fixedwith the supporting frame; the lower connecting frame is arranged on the upper connecting frame so as to lock and fix the lamp holder end cover on the supporting frame, the side frame and the upper connecting frame. The LED modular street lamp holder has the advantages of high light efficiency, stability, energy conservation, environmental protection and the like, has convenient and fast assemblyand a good radiating effect, and can meet the requirements of LED roadway lighting at different powers by increasing or decreasing the number of the LED light source modular components.

Description

technical field [0001] The invention belongs to the technical field of semiconductor lighting, in particular to an LED modular street lamp head with an adjustable irradiation angle. Background technique [0002] As a novel solid light source, LED (light emitted diode, collectively referred to as light-emitting diode or light-emitting diode, is a solid light source). The difference from traditional light sources is that the life of LED light source is related to the individual and the use environment; it has nothing to do with the switch. There is no need for switch test; the production process and products are almost pollution-free, not afraid of vibration, can realize 0~100% continuous dimming, can work under ultra-low voltage, can continuously work in the working state of switching, flashing and its output light It has many unique advantages such as orientation. [0003] At present, there are many kinds of LED street lamps at home and abroad, and their performances are un...

AI Technical Summary

Problems solved by technology

And none of the street lamps are designed according to the characteristics of the LED light source itself, but the LED is placed in the traditional street lamp shell

Due to the constraints of LED lamps in terms of quality and heat dissipation requirements, it is difficult to meet the lighting requirements of ultra-high-power LED street lamps

[0004] Moreover, LED road lights on the market have relatively large attenuation at present, and it is difficult to guarantee the life expectancy. At the same time, the waterproofing is also very poor. Most of them will have water ingress after a period of use.
