LED flood light and manufacturing method thereof

Abstract

The invention discloses an LED flood light and a manufacturing method thereof. The LED flood light comprises a light body, a PCB, a plurality of LED chip sets and a secondary light distribution structure; the secondary light distribution structure is fixedly arranged on the light body, and a cavity is formed between the secondary light distribution structure and the light body; the PCB is fixedly arranged on the light body and located in the cavity; all the LED chip sets are fixedly arranged on the PCB; the secondary light distribution structure is provided with a plurality of lenses, each lens corresponds to one LED chip set, and each LED chip set comprises at least an LED chip. By adopting the technical scheme of the LED flood light, the lenses are prevented from being separately arranged by arranging the secondary light distribution structure; accordingly, the glue usage mount is greatly decreased, the influence that a glue filling mode serves as a waterproof mode is reduced, the too long cooling time can be avoided, and the extremely high application value is achieved.

Description

technical field [0001] The present invention relates to LED lighting, in particular to an LED floodlight and a manufacturing method thereof. Background technique [0002] LED floodlights, that is, lamps that use LED light sources to project light, including LED line lights, guardrail lights, fluorescent lights or wall washers; for example, the current urban lighting projects are mainly wall washers with LED light sources. Wall washer, which makes the light wash the wall like water, is mainly used for architectural decoration lighting, and is also used to outline the outline of large buildings. Because LED has energy saving, high luminous efficiency, rich colors, long life, etc. characteristics, so the wall washer of other light sources is gradually replaced by LED wall washer. [0003] Compared with traditional wall washer, LED wall washer has the social benefits of energy saving and environmental protection. LED lamps save about 70% of electricity than incandescent lamps, ...

AI Technical Summary

Problems solved by technology

This results in a long production cycle, and the production workshop must have a large enough place to place semi-finished products, the production capacity is greatly limited, and the process cost is too high

[0011] At present, LED wall-washing lights, spotlight lights and other landscape lighting, the waterproof structure of which is mostly treated with glue filling. Although the waterproof glue filling method can achieve waterproof effect to a certain extent, the lamps often encounter the following problems in the production process. : The production of lamps is glued and waterproof, which makes the quality of the whole lamp heavier, which increases the transportation cost of lamps and the flexibility of the product; the use of glue as a waterproof method prolongs the production cycle, resulting in low production efficiency and affecting the production capacity of lamps ;The glue filling method is used as a waterproof me...
