Modularized, replaceable and easily maintainable LED illumination lamp

Abstract

The invention belongs to the technical field of illuminating lamps, and in particular relates to a modularized, replaceable and easily maintainable LED illumination lamp which comprises an LED basic module, a lamp base and a lamp shell, wherein step surfaces of the LED basic module and the lamp base are connected and firmly locked, and the sides of the lamp shell and the lamp base are hinged to ensure that the lamp shell can turn over. Heat radiating fins are thoroughly distributed on the external surface of the LED basic module, an aluminum base plate is welded on the internal surface of theLED basic module and provided with an optical device, and the lower plane of the LED basic module is provided with sealing glass. A waterproof joint of the LED basic module is connected with a waterproof joint of an LED driving power supply or a controller. The invention has convenient maintenance, only needs to replace the damaged module when a light source is partially damaged, solves the problem that the whole lamp has to be replaced if the light source is partially damaged, and effectively saves the cost through the modularized concept. The invention enlarges the average heat radiating area of the LED light source, can effectively prevent bird manure or road dust and the like from depositing on the heat radiating fins in the application of road illumination, and is helpful for heat radiation.

Description

technical field [0001] The invention belongs to the technical field of lighting fixtures, and in particular relates to a modular, replaceable and easy-to-maintain LED lighting fixture. Background technique [0002] With the rapid development of semiconductor lighting technology, the luminous efficiency of high-power white LEDs has reached 120lm / w, while its price and cost have been decreasing year by year. Nowadays, high-power LEDs have been gradually applied in street lights, tunnel lights, garden lights and indoor home lighting. [0003] With the wide application of high-power LEDs, it is inevitable to face the problems of lamp maintenance and light source replacement, especially in the field of road lighting. As we all know, traditional lamps such as high-pressure sodium lamps, metal halide lamps, etc., if only the light source itself is broken and cannot work, and there is no problem with the circuit part of the lamp, such as the ballast, you can directly replace the li...

AI Technical Summary

Problems solved by technology

In this way, if part of the LED light source fails and is damaged, it is basically impossible for municipal personnel (such as the staff of the street light station) to replace the LED light source, then the whole lamp has to be discarded and replaced with a new lamp instead of the light source.

In this way, on the one hand, the cost is high for the user, and on the other hand, it is a pity that some LEDs fail and the whole is discarded.
