Description

LED patio light

This creation belongs to the field of application of LED lighting, especially an LED patio lamp, which combines a heat pipe cooling module and a concentrating cover as a two-stage heat dissipation structure, which greatly increases the heat when dissipating the illumination, and the light passes through the reflection plate. The color changes quickly and the color of the illumination is quickly adjusted to achieve an environmental change.

According to the advantages of high efficiency, low power consumption, long life, cold illumination, fast response speed and high color consistency, Light Emitting Diodes (LED) have gradually replaced traditional light sources for lighting applications. However, as LED lighting lamps have higher power lighting applications, such as: intensive LED lamps such as recessed lights and patio lights, they will accumulate considerable heat during use, resulting in a significant reduction in the service life of LEDs and lighting. The luminous efficacy of the time is degraded.

General patio lights are used for hanging, such as factories, store warehousing, parking lots, gas stations, sports fields, underground roads, etc., which mainly include a inverted bowl-shaped lampshade and a light-emitting lamp body, which are formed by the inner wall of the bowl-shaped lampshade. The specific curvature surface is used to concentrate the light source emitted by the illuminating lamp body so that the light is irradiated over a long distance without excessive attenuation. However, a patio lamp made of high-power LED, or LED patio lamp, refers to an LED lighting fixture with a power between 70W and 260W. Because of the high power consumption, the accompanying heat is relatively high. , it is easier to shorten the service life of LEDs and reduce the luminous efficacy when lighting, so how It is even more important to ensure the heat dissipation during use.

At present, there are several common types of heat dissipation methods. The most common one is to make a heat conductor by using a metal material such as aluminum alloy or copper alloy, which is directly connected to an LED circuit substrate. The heat conductor is provided with a plurality of heat dissipation fins. In use, heat is dissipated from the heat dissipating fins to the outside through the conduction of the heat conductor. Since the heat generated by the LED patio lamp is extremely large, one side of the heat sink fins is added. The cooling fan, according to the method of forced air intake, quickly and efficiently dissipates heat.

However, although the heat dissipation structure applied to the LED patio lamp has a good heat dissipation effect, it is bulky, heavy, and must have additional power for the use of the heat dissipation fan. Therefore, how to design an LED patio lamp with small size, light weight and good lighting and heat dissipation effect is the goal of various manufacturers.

For ease of manufacture, the base and the top plate are integrally formed. Or the top plate and the reflector are integrally formed. Or the pedestal, the top plate, and the reflecting plate are integrally formed. Not only does it need to be assembled separately, but it can also enhance the conduction effect of the original heat dissipation, and avoid the heat dissipation efficiency of the interface due to the thermal resistance of the interface.
