Description

Technical Field

[0001] The utility model relates to the field of street lamps, and more specifically, to an LED street lamp based on an active heat dissipation lamp holder. Background Art

[0002] LED street lights are street lights that use LEDs as light sources. Compared with traditional street lights, they have the advantages of low energy consumption, high light efficiency, and long life. In recent years, with the continuous advancement of technology and the improvement of environmental awareness, the application scope of LED street lights will become more and more extensive.

[0003] Existing streetlights often require complete lamp replacement when the LED lighting unit is damaged or performance degrades, which not only increases the difficulty and cost of maintenance. Because lamp holders are typically installed at a high position and have complex internal structures, disassembly and assembly are cumbersome, requiring specialized maintenance personnel and tools, increasing maintenance time and costs. LED lamp beads generate a large amount of heat during operation. If heat dissipation is poorly managed, the heat will accumulate inside the lamp holder, causing the LED lamp beads to heat up, thereby affecting their luminous efficiency and lifespan. Some streetlight lamp holders use passive heat dissipation methods, which are significantly affected by the environment, have limited heat dissipation effectiveness, and cannot guarantee the stable operation of LED lamp beads in high-temperature environments.
