The cross section of the rubber gasket is arranged in a T shape and comprises a ring surface and a ring wall connected to the middle of the back of the ring surface. During installation, the rubber gasket is sleeved on the upper end edges of the support shell and the LED lens, the vertical side wall of the rubber gasket is arranged in a gap between the support shell and the LED lens to fill the gap, and then the rubber gasket is pressed on the rubber gasket through the annular cover, so that the LED lens is more tightly installed in the support shell and can be prevented from shaking.

Description

An anti-shake lens support structure

technical field

The utility model relates to the field of lamps, in particular to an anti-vibration lens support structure.

Background technique

At present, LED light sources are gradually replacing incandescent and fluorescent light sources with their long life, no pollution, and high light efficiency. However, LED light will generate heat, and heat accumulation will lead to high temperature, which will directly affect the service life of LED and reduce the luminous efficiency. Also due to the luminous characteristics of the LED, the light emitted by it will escape towards the side and surroundings, and the luminous intensity to the surroundings accounts for about 20%-30% of the total luminous intensity. There will be astigmatism problems during use, and the light emitted by the LED will Impaired by scattering. In order to solve the astigmatism problem of LEDs, people think of using a lens capable of concentrating light on the lamp to solve it. The lens is generally installed through a lens bracket, and the lens is installed in the lens bracket, and then installed into the lamp body. The connection between the existing lens bracket and the lens is not tight, and the lens is easy to shake under the condition of external shaking after the lens is installed.
