Problems solved by technology

When the lamp 10 is used outdoors, the rubber seal 15 will age faster due to sunlight passing through the transparent member 14 and irradiating the rubber seal 15 for a long time, resulting in poor sealing performance of the LED lamp 10

Abstract

An LED lamp comprises an upper shell, a lens, a drive circuit board and an LED. The upper shell is provided with an accommodating groove, and a light hole is formed at the bottom of the accommodating groove. The lens is accommodated in the accommodating groove and covers the light hole. A lower shell is provided with an electrical appliance groove, and one side, close to the opening of the electrical appliance groove, of the lower shell is fixedly connected with one side, close to the light hole, of the upper shell. The drive circuit board is accommodated in the electrical appliance groove. The LED is fixed onto the drive circuit board directly and opposite to the position of the light hole. The upper shell and the lens are respectively made of two plastic materials similar in the molecular structure, and the lens is made of transparent plastics. The lens is welded with the side wall of the accommodating groove by means of ultrasonic welding so as to have the opening of the accommodating groove sealed. Due to the fact that rubber seals easy to age after exposure in the sun are avoided being applied to the upper shell and the lens of the LED lamp, long term usage of the LED lamp is ensured, and leakproofness is especially good when the LED lamp is used outdoors. The invention further provides a manufacturing method of the LED lamp.

Description

【Technical field】 [0001] The invention relates to a lamp, in particular to an LED lamp and a manufacturing method thereof. 【Background technique】 [0002] At present, there is often a mechanical fit between the shell and the transparent part of the lamp. At the same time, the separate design of the reflector and the transparent part brings about an increase in materials, so that the fit between the lamps often affects the reliability of the entire lamp. Once the fit fails, the inside of the lamp The entry of dust, gas, liquid and other objects will cause problems such as internal corrosion of the lamps, which will lead to lighting failure of the lamps, safety accidents and other problems, bringing huge losses to the market and customers. This problem often requires the designer to spend a lot of time and energy to solve it, and sometimes even re-mold the mold in order to achieve the purpose of sealing the joint. [0003] see figure 1 , the traditional LED lamp 10 includes ...
