Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a column-type LED warning lamp with a plastic-coated aluminum shell. Background Art

[0002] Warning lights are generally used to maintain road safety, typically on police vehicles, construction vehicles, fire trucks, ambulances, security and management vehicles, road maintenance vehicles, tractors, emergency A / S vehicles, and machinery. Warning lights are generally available in various lengths based on vehicle type and purpose, with shade combinations available, allowing for multiple shade colors on one side. Furthermore, depending on the light source, they can be categorized as rotating bulbs, LED flashers, or xenon strobe lamps. LED flashers are an upgraded version of rotating bulbs, offering longer life, greater energy efficiency, and lower heat generation.

[0003] LED warning lights also generate a certain amount of heat during use. High-power LED warning lights generate even more heat. If the heat dissipation is not good enough, it will affect the lifespan of the lamp. Therefore, the heat dissipation problem of LED during use has become one of the main research directions of relevant technical personnel. Currently, the structure of LED street lights generally consists of a heat dissipation housing, power supply, light source module, etc. The heat dissipation housing generally has heat dissipation fins. The heat dissipation performance of the heat dissipation fins is poor. To improve the heat dissipation performance of LED warning lights, we propose a column-type LED warning light with a plastic-coated aluminum housing. Utility Model Content

When the LED warning light dissipates heat, the micro-vacuum pump is started, and the hot air flow inside the LED warning light will be filtered and purified by the air filter and then enter the air guide coil. The hot air flow circulating in the air guide coil will be dissipated to the outside through the air guide coil. A top-down airflow will be formed inside the LED warning light, and the circulating airflow will take away the heat generated by the LED light board and the driver, thereby improving the heat dissipation of the lamp body and solving the background problem.
