Description

LED lamp housing with waterproof function

technical field

The invention relates to an LED lamp shell, in particular to an LED lamp shell with waterproof function.

Background technique

With the improvement of LED luminous efficiency, LED gradually replaces traditional light bulbs, and is used in various indoor lighting equipment, and is also used in outdoor lighting. quite important.

Therefore, the prior art provides an LED lamp housing, as shown in FIG. 7 , which includes a cover 70, a body 71 and a waterproof rubber strip 72. The inner thread 702 is provided on the inner side of the side plate 701 of the cover 70. The upper end of the body 71 protrudes upwards to form a ring convex plate 711, and the outer side of the ring convex plate 711 is provided with an external thread 712, and the external thread 712 is opposite to the internal thread 702. The waterproof rubber strip 72 is embedded in the upper end of the body 71, and the waterproof rubber strip 72 is arranged on the The outer side of the ring convex plate 711 is fitted with the external thread 712 of the body 71 through the internal thread 702 of the cover 70, so that the cover 70 and the body 71 are screwed together, and the waterproof rubber strip 72 is pressed to make the cover 70 and the body There is no gap between 71, and the waterproof effect is achieved.

However, the LED lamp shell of the prior art, though the internal thread 702 and the external thread 712 screwing and compressing the waterproof rubber strip 72, can be effective and ensure the waterproof performance, but due to the bottom end of the external thread 712 and the body 71 There is no space between the top sides, so that when the cover 70 and the body 71 are screwed together, it is difficult to clearly know the distance between the bottom side of the cover 70 and the top side of the body 71, and then it is impossible to know the compression amount of the waterproof rubber strip 72, so that The compression of the waterproof rubber strip 72 is difficult to control. If the compression is too small, the waterproof performance will be poor. If you want to ensure the waterproof performance, it is easy to over-compress and make the waterproof rubber strip 72 elastically fatigued, aged or broken, and the waterproof rubber will be damaged. The service life of the strip 72 is shortened to affect the water resistance.

Contents of the invention

In view of the above-mentioned shortcomings of the prior art, the present invention provides an LED lamp housing with waterproof function, which can effectively control the compression amount of the waterproof rubber strip, so as to meet the requirement of good waterproof performance without shortening the service life of the waterproof rubber strip. .
