LED tube with automatic cooling function

Abstract

The invention relates to an LED tube with an automatic cooling function. The tube comprises a casing and two connecting blocks, the casing is internally provided with a substrate and a plurality of lamp beads, a side, away from the lamp beads, of the substrate is provided with a plurality of cooling assemblies, air intake pipes are disposed below the two ends of the casing, each cooling assembly comprises an opening, a cooling pipe, a heat absorbing block, a pressing ring, a limiting ring and a plurality of springs, each cooling pipe is internally provided with a sealing plate, a sealing blockand a vertical rod, a plurality of through holes are formed in the outer circumferences of the ends, located in the casing, of the cooling pipes, the LED tube with the automatic cooling function absorbs heat through the heat absorbing block and then expands into a support pipe to support the vertical rod, so that the sealing block is separated from a sealing hole, convenience is provided for hotair in the casing to be discharged, external cold air enters the casing, thereby achieving the purpose of cooling, the service life of the LED tube is prolonged, and the practicability of the LED tubeis improved.

Description

technical field [0001] The invention relates to the field of LED lighting equipment, in particular to an LED lamp tube with an automatic cooling function. Background technique [0002] LED tubes are also commonly known as light tubes and fluorescent tubes. The light source uses LEDs as illuminants. LED tubes have many advantages such as high luminous efficiency, low heat generation, and power saving. They are often used in general lighting, office buildings, shopping malls, restaurants, schools, and families. , factories and other indoor lighting. With the increasingly mature and perfect technology in the photoelectric industry, in order to save electricity to meet the requirements of energy conservation and environmental protection, and to meet the needs of different users, more and more companies have developed LED lamps to replace traditional fluorescent lamps. [0003] However, the existing LED lamp tube has simple structure and single function. Inside the lamp tube, th...

Problems solved by technology

[0003] However, the existing LED lamp tube has simple structure and single function. Inside the lamp tube, the lamp beads work in a closed ambient temperature, and the heat generated cannot be dissipated. As the lighting time increases, the temperature inside the lamp tube gradually increases. , due to the lack of a corresponding cooling device, the lamp beads continue to work in a high temperature environment, shortening the service life of the lamp beads and the lamp tube, resulting in reduced practicability of the existing LED lamp tubes
