Description

A LED Lawn Light

Technical field:

The utility model relates to the technical field of LED lamps and their applications, in particular to an LED lawn lamp.

Background technique:

With the development of social economy, people pay more and more attention to the beautification of the environment. In places such as parks, squares, and road green belts, you can usually see the existence of lawn lights. At night, the light emitted by lawn lights can not only illuminate the surrounding area, but also greatly beautify the environment, bringing people a sense of beauty and comfort. .

Traditional lawn lamps use incandescent lamps or fluorescent lamps as light sources, which are basically eliminated due to large power consumption, high heat generation, and short life. LED is more and more widely used as a light source, because of its high luminous efficiency and low power consumption, it is an energy-saving lamp, and its light is soft, not dazzling, and it is an environmentally friendly light source, so LED is an ideal light source for lawn lights. LED lawn lights in outdoor public places also require a certain power due to the need for brightness, so their heat generation cannot be ignored. Once the heat cannot be dissipated in time, it is easy to affect the service life of the LED light source. Yes, the above problems exist.

Utility model content:

The purpose of the utility model is to overcome the above-mentioned shortcomings of the prior art, and provide an LED lawn lamp with a simple structure and good heat dissipation effect.

The technical solution adopted by the utility model is: LED lawn lamp, including lamp holder, lampshade, LED light source and light-transmitting cover body, the support part for installing LED light source is formed on the upper part of the lamp holder, and it also includes a radiator, and the radiator is set Between the support part and the LED light source and its reflective cup.

Specifically, the support part is cross-shaped, that is, the heat sink is supported by four ribs of the support part. In this way, not only can the material of the lamp holder be saved, but more importantly, most of the outside of the heat sink is exposed outside, which is conducive to increasing the heat dissipation area and improving the heat dissipation effect.

A grating is arranged inside the light-transmitting cover body, which can enhance the ornamental effect of luminescence.

The lampshade is a reflector, that is, its inner surface is a reflective surface, so as to increase the reflection effect of light and reduce light loss.

The LED lawn lamp of the utility model solves the problems of bad heat dissipation effect of the existing LED lawn lamp, improves the heat dissipation effect of the LED, is beneficial to ensure the normal use of the LED lawn lamp, and prolongs the service life of the LED lamp.

Description of drawings:

Fig. 1 is a perspective view of the utility model;

Fig. 2 is a schematic cross-sectional structure diagram of the utility model.

Detailed ways:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, the utility model LED lawn lamp includes a lamp holder 1, a lampshade 2, an LED light source 3 and a light-transmitting cover body 4, and the whole is a cylindrical structure, wherein the light-transmitting cover body 4 is installed on the lamp holder 1 and the light-transmitting cover body 4. Between the lampshades 2, materials such as glass are usually used to make. (Because the transparent cover 4 is in a transparent state, it is not shown in FIG. 1).

Specifically, the bottom of the lamp holder 1 is cylindrical, and extends upwards from the bottom to form a "cross" shape to form a supporting part 11, which can greatly save the material of the lamp holder. The four ribs of the support part 11 support a radiator 5, the radiator 5 is bowl-shaped, and the LED light source 3 and the reflector cup 31 are installed in it, so the heat generated by the LED light source 3 is easily distributed through the radiator 5 to maintain the LED light source. normal working temperature.

Usually, the heat sink 5 is made of a material with a high thermal conductivity, such as a metal material, etc. Obviously, the materials of the supporting part 11 and the lamp holder 1 can be consistent with the material of the heat sink, and can be integrally formed to obtain a better heat dissipation effect. .

In order to further improve the appearance and light effects of the utility model LED lawn lamp, the utility model has also made the following improvements: a grating 6 is provided inside the transparent cover body 4 to enhance the ornamental effect of light; the lampshade 2 adopts The reflector, that is, its inner surface is a reflective surface, to increase the reflection effect of light and reduce light loss.

To sum up, the LED lawn lamp of the utility model has good heat dissipation effect, simple structure, and can save manufacturing materials and reduce costs.
