Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to a detachable heat dissipation structure of an LED lamp. Background Art

[0002] LED lamps are lighting equipment that use LEDs (light-emitting diodes) as light sources. LEDs are semiconductor devices that generate light when current passes through them. Compared with traditional incandescent lamps and fluorescent lamps, LED lamps have many advantages, such as high efficiency and energy saving, long life, strong durability, environmental protection and no pollution. Due to the small size and plasticity of LEDs, the design of LED lamps is flexible and diverse, and can be applied to various fields such as indoor lighting, outdoor lighting, landscape lighting, etc. With the development of science and technology, LED lamps are becoming increasingly important in the lighting industry and have become the mainstream choice for energy saving and environmental protection.

[0003] Traditional LED lamps are usually composed of core components such as metal shells, drive circuits, LED chips, and lampshades. In terms of heat dissipation design, many LED lamps use ventilation holes around the metal shell to complete the heat dissipation process using the convection of the surrounding air. This heat dissipation method is mainly passive heat dissipation, that is, it relies on natural convection and radiation heat dissipation to reduce the temperature. However, this design often makes it difficult to directly implement effective active heat dissipation for the LED chips tightly installed inside the metal shell, because the LED chip is the part that generates the most heat in the lamp. If the heat dissipation is insufficient, heat will accumulate, resulting in excessive temperature, affecting the brightness, efficiency and life of the LED lamp, and may even cause safety hazards.

[0004] Based on this, we propose a detachable heat dissipation structure of an LED lamp to solve the above-mentioned problems. Utility Model Content
