Air-cooling radiation LED (light emitting diode) lamp

Abstract

The invention discloses an air-cooling radiation LED (light emitting diode) lamp, which comprises an LED lamp tube and a power supply. The lamp is characterized by comprising a protective controller and an air-cooling radiator, wherein the protective controller consists of a singlechip circuit, a temperature sensor, an electronic switching circuit and a voltage conversion circuit, and the temperature sensor and the electronic switching circuit are respectively connected with the singlechip circuit; the voltage conversion circuit is connected with the power supply, and respectively connected with the singlechip circuit, the temperature sensor and the electronic switching circuit; the air-cooling radiator consists of a fan and a radiator, and the fan is connected with the power supply; and the LED lamp tube is fixedly connected to the radiator, and is connected with the electronic switching circuit of the protective controller and the power supply. In the use process, the air-cooling radiation LED lamp can automatically detect the temperature of the radiator, and performs an automatic overheat protecting function to the LED lamp tube, so that the problems that the lamp has a large radiator and high cost by adopting a natural radiation mode, and poor wind and shaking resistance caused by overweight dead weight of the lamp can be solved.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an air-cooled LED lamp for heat dissipation. Background technique [0002] LED lamps are entering the market rapidly, but the existing high-power LED lamps encounter the following problems, which seriously hinder the market promotion of high-power LED lamps. [0003] (1) The radiator of high-power LED lamps is too bulky. The radiators of high-power LED lamps in the existing mode are all made of aluminum radiators, which completely rely on natural methods to dissipate heat. The aluminum radiator of natural heat dissipation has a large shape and heavy weight. For example, the radiator of a 100-watt LED lamp has a self-weight of more than 15 kilograms. It is difficult to reduce the weight and overall size of the entire lamp. When the lamps are used outdoors, the heavy weight and large appearance make it difficult to improve the wind resistance of the lamps, which increases the design difficulty and ...

AI Technical Summary

Problems solved by technology

The aluminum radiator of natural heat dissipation is large in shape and heavy in weight. For example, the radiator of a 100-watt LED lamp has a self-weight of more than 15 kg. It is difficult to reduce the weight and size of the entire lamp.

When the lamps are used outdoors, the heavy weight and large appearance make it difficult to improve the wind resistance of the lamps, which increases the design difficulty and cost of the installation structure of the fixed lamps, and correspondingly increases a lot of difficulty for transportation, installation and maintenance.

[0004] (2) The existing high-power LED lamps lack protection measures. When the heat dissipation is abnormal, the LED lamp tube, as a relatively expensive device in the lamp, cannot be effectively protected. It will work abnormally for a long time so that it will be burned and scrapped, which increases the cost of use.

[0005] (3) If there is a problem with the heat dissipation effect of the radiator of the existing high-power LED lamps, it cannot be discovered in time, and the lamp will not be found to be in a sick state until the lamp tube is burnt out. At this time, it is too expensive to deal with it

[0006] It can be seen that there are defects and inconveniences in the design and production of existing high-power LED lamps. How to make LED lamps reach the theoretical service life in actual use and improve the quality level of lamps is one of the current important research and development topics in this field. , which is also an urgent goal for the industry to improve
