Description

The ramp cup which shines}

The present invention relates to a shining lamp cup, and more particularly to a waterproof gasket structure of the assembling shining lamp cup.

Since light emitting diodes (LEDs) have many advantages such as brightness, low power, and long lifespan, they are widely used in various lighting fixtures, and replace light bulbs of conventional light bulbs and fluorescent lamps. However, when LED is used as a light source of an outdoor lighting lamp, there are often problems in terms of waterproofing, and a solution to this problem becomes a problem. The most common means of waterproofing is to insert a waterproof gasket between two screwing members. In other words, the above-mentioned waterproof gasket is brought into close contact between the lamp cup and the lamp base plate, thereby achieving the effect of waterproofing by eliminating the gap created in the process of assembling the lamp cup and the lamp base plate. In addition, there is a method to bond the lamp cup and the lamp base plate with a waterproof adhesive to more effectively prevent the penetration of water. However, since this method is difficult to disassemble the lamp, there is no way to replace it later when the LED in the lamp fails. As described above, in a situation in which dismantling for replacing an LED is required, a method of achieving a waterproof effect by using the waterproof gasket is commonly used. However, when using the waterproof gasket in the conventional screwed structure, the adhesion by screwing the pressure gasket to achieve the purpose of waterproofing. However, in the screwed structure, even if a very small reverse rotation occurs, the adhesive force of the waterproof gasket is reduced, causing a gap. In particular, as the dismantling and assembly operations are repeatedly performed, water easily penetrates through the gap and loses the waterproofing effect. There is this. The present invention was created to solve the above-described problems of the prior art, and researched with a whole heart on the basis of scientific principles, to devise a waterproof gasket structure that effectively improves the above-described problems of the prior art.
