Self-ballast LED (Light Emitting Diode) spot lamp

Abstract

The invention relates to a self-ballast LED (Light Emitting Diode) spot lamp. The LED spot lamp comprises a lamp head, an adapter, an air distribution hood, a power supply device, a fan, a lamp body, a light source, a reflection cup and a surface cover, wherein the lamp head is fixedly arranged at the rear end of the adapter; the power supply device is arranged inside the adapter; the air distribution hood is integrally convex, the main body of the air distribution hood is cylindrical, the top of the air distribution hood is provided with an edge overturning outwards, and an air inlet port is formed in the edge; the air distribution hood is fixedly arranged inside the adapter; the fan is fixedly arranged at the bottom of the air distribution hood; the lamp body is fixedly arranged at the bottom of the inner side of the air distribution hood; the light source is attached in the lamp body; the reflection cup is arranged above the light source; the surface cover is arranged above the reflection cup; the reflection cup is fixedly arranged inside the air distribution hood through the surface cover. A magnetic suspension fan is arranged on an aluminum radiator, and a wind deflector device is designed for matching with the fan to form a good wind inlet and outlet radiating loop and exhaust the internal heat of the lamp, thus the difficulty of heat radiation of an LED lamp is solved, and an energy-saving LED lamp with high power of 30W and high light efficiency is realized.

Description

technical field [0001] The invention discloses an LED spotlight, in particular to a self-ballasted LED spotlight. Background technique [0002] With the continuous maturity and development of LED lighting technology, LED lighting is more and more widely used in people's daily life. At present, the commonly used LED lighting devices are LED bulb lamps and LED spotlights. In the prior art, for the application of LED lighting technology, the problem of heat dissipation still needs to be solved urgently. In high-power LED lighting devices, passive heat dissipation It often cannot meet the heat dissipation requirements. It is usually designed as an active heat dissipation technology, that is, the design of the high thermal conductivity aluminum profile lamp body structure is the main heat sink, and the high thermal conductivity silicone grease is filled between the lamp body and the light source to closely cooperate, and the heat of the light source is quickly transmitted through...

Problems solved by technology

At present, the commonly used LED lighting devices are LED bulb lamps and LED spotlights. In the prior art, for the application of LED lighting technology, the problem of heat dissipation still needs to be solved urgently. In high-power LED lighting devices, passive heat dissipation It often cannot meet the heat dissipation requirements. It is usually designed as an active heat dissipation technology, that is, the design of the high thermal conductivity aluminum profile lamp body structure is the main heat sink, and the high thermal conductivity silicone grease is filled between the lamp body and the light source to closely cooperate, and the heat of the light source is quickly transmitted through the lamp body. Outside the lamp body, it uses a built-in fan to carry out forced air circulation to dissipate heat. Although the heat dissipation effect is good, the product is generally large in size, which usually cannot meet people's pursuit of miniaturization, and its production and assembly structure is complex and the production efficiency is low.
