An internal and external pressure balance structure of a liquid led lamp and a liquid led lamp

Abstract

The invention discloses an internal and external pressure balance structure of a liquid LED lamp. The internal and external pressure balance structure of the liquid LED lamp comprises an LED illuminating body, the LED illuminating body is installed in a shell, and the shell is filled with heat conducting liquid; a channel is formed in the LED illuminating body, one end of the channel is communicated with the outer portion of the shell, the other end of the channel is communicated with the cavity of the shell, and a nano air permeable layer for limiting the heat conducting liquid to pass is arranged on the end, communicated with the cavity, of the shell. The invention further discloses the liquid LED lamp including the internal and external pressure balance structure. The internal and external pressure balance structure of the liquid LED lamp and the liquid LED lamp can maintain the shell internal and external pressure balance of the liquid LED lamp, and the LED is designed to be with large power.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an internal and external pressure balance structure of a liquid LED lamp and the liquid LED lamp. Background technique [0002] In the prior art, LED lamps have been widely used. However, due to the high heat emitted by the LED lamps, the improvement of LED power is restricted, and the excessively high temperature causes color cast of LED light. [0003] In order to solve the problem of LED heat dissipation, the industry seeks materials with high heat capacity for LED heat conduction. Usually, various high heat capacity liquids such as water, heat transfer oil, and paraffin oil are filled in the lampshade, and the high heat capacity liquid surrounds the LED light-emitting chip to make the LED The light-emitting chip dissipates heat quickly. [0004] However, when LEDs emit light, a large amount of heat is generated, especially for high-power LEDs. The heat expands the heat-con...

Problems solved by technology

[0004] However, when LEDs emit light, a large amount of heat is generated, especially for high-power LEDs. The heat expands the heat-conducting liquid, which in turn increases the pressure in the light-transmitting outer cover. After the pressure increases, the temperature of the heat-conducting liquid continues to rise, forming a cycle. Over time, the light-transmitting cover may even be easily broken. Therefore, the power of the prior art liquid-cooled LED lamp is still relatively limited, and this case arises from this
