LED embedded lamp

Abstract

The invention relates to an LED embedded lamp comprising a lamp body and an LED lamp installed in the lamp body, wherein optical lenses in one-to-one correspondence are covered on the LED lamp, and transparent glass and a lamp cover are sequentially arranged on the upper end face of the lamp body. A step which divides the lamp body into two hollow cavities containing the LED lamp and an electronicdriver respectively is arranged in the lamp body, the step face of the step is in a horizontal or inclined shape, the LED lamp is fixedly installed on the step face by an aluminium base plate, the bottom of the step is provided with a heat-radiation fin which is beneficial to heat radiation, the section of a port at the upper end face of the lamp body is in a superior arc shape, an air outlet hole which is communicated with the hollow cavities below the step is arranged on the upper end face of the lamp body, the upper part of the air outlet hole is exposed on the upper end face of the lamp body, the lamp cover is covered above the air outlet hole, the section of the transparent glass arranged at the upper end face of the lamp body is in a superior arc shape, and a waterproof washer withthe section in a superior arc shape is arranged between the upper end face of the lamp body and the transparent glass. The invention has strong heat-radiation capability and convenient installation, increases the bearing power greatly and enhances the waterproof capability.

Description

technical field [0001] The invention relates to a buried lamp, in particular to an LED buried lamp with high power and good heat dissipation. Background technique [0002] With the development of social economy and the gradual improvement of people's living standards, people's requirements for quality of life are getting higher and higher. In places such as residential areas or outdoor squares, in order to make the environment more conducive to people's leisure walking without damaging the landscape, the use of buried lights is becoming more and more common. Since the buried lamp is installed in the outdoor open space, it is directly affected by the external environment. The temperature of the lamp cover of the traditional buried lamp is relatively high, usually above 70 degrees, which is easy to burn people, while the temperature of the lamp cover of the LED buried lamp is generally around 55 degrees. In addition, because the LED lamp has high light source light efficiency...

AI Technical Summary

Problems solved by technology

The temperature of the lamp cover of the traditional buried lamp is relatively high, usually above 70 degrees, which is easy to burn people, while the temperature of the lamp cover of the LED buried lamp is generally around 55 degrees. In addition, because the LED lamp has high light source light efficiency, energy saving, Due to the characteristics of environmental protection and long service life, it has become an inevitable trend for LED in-ground lights to replace traditional in-ground lights.

[0003] The structure of the existing LED buried lamp is generally as follows: the LED lamp is installed on the same horizontal surface of the lamp body. In order to prevent water ingress, there are generally no air holes on the lamp cover to facilitate air circulation. Although the air in the embedded parts can pass through the small The gap communicates with the outside world, but because the LED lamps are installed on the same level, air convection cannot be formed, and the heat dissipation capacity is poor. Therefore, it cannot meet the needs of large power, making the existing LED underground lamps unable to be used for trees or external walls. Places for higher power lighting applications

In addition, due to the installation of the existing LED underground lamps, it is necessary to fix the lamp body in the embedded parts first, and then fix the lamp cover. The exposed screw heads on the lamp cover are easy to be damaged by interested people. The cover is usually manually operated. If the operator does not pay attention, the lamp cover will not be installed tightly, the waterproof will not be controlled, and it will be easily damaged.
