Description

Technical fields:

[0001] This utility model relates to the field of downlights, and in particular to a waterproof downlight. Background technology:

[0002] As the fourth generation of lighting source, LEDs have significant advantages in energy saving and lifespan. With social development, the problem of lighting energy consumption in daily life has become increasingly prominent. Therefore, LED lighting fixtures with significant energy-saving advantages are becoming more and more popular.

[0003] Since most downlights are installed on indoor ceilings and do not need to be exposed to wind and rain, their waterproof performance is neglected. Therefore, they are less resistant to humid weather such as the humid season, and moisture can easily penetrate from the front or rear of the lamp body, affecting the stability of their lighting performance. Utility model content:

[0004] The purpose of this invention is to provide a waterproof downlight, which solves the problem that existing downlights are weakly protected against humid weather such as the return of spring, and that moisture can easily penetrate from the front or rear of the lamp body, affecting the stability of its lighting performance.

[0005] The objective of this utility model is achieved through the following technical solution.

[0006] The purpose of this utility model is to provide a waterproof downlight, including a lamp housing. A deep groove is provided on one side of the lamp housing, and an LED light source is installed in the deep groove. A step is provided in the deep groove, and the step surrounds the LED light source in a circle. A lens is installed on the step, and a waterproof rubber ring is provided between the lens and the step. A through hole is provided in the deep groove, and an electric wire is connected to the LED light source and extends out of the through hole. A waterproof terminal is installed on the through hole, and the electric wire passes through the waterproof terminal for fixation.

[0007] Furthermore, the lens has an edge around its periphery, and screws are installed on the edge, which pass through the edge to connect and fix it to the step.

[0008] Furthermore, a lamp cup is provided on the lens, and the lamp cup is fixed to the inside of the lamp housing.

[0009] Furthermore, the lamp cup is fastened to the lamp housing.

[0010] Furthermore, several heat dissipation strips are provided at the top of the lamp housing.

[0011] Furthermore, spring clips are installed on both sides of the lamp housing.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1) This utility model describes a waterproof downlight, including a lamp housing. A deep groove is provided on one side of the lamp housing, and an LED light source is installed in the deep groove. A step is provided in the deep groove, and the step surrounds the LED light source. A lens is installed on the step, and a waterproof rubber ring is provided between the lens and the step. A through hole is provided in the deep groove, and an electric wire is connected to the LED light source and extends out of the through hole. A waterproof terminal is installed on the through hole, and the electric wire passes through the waterproof terminal for fixation. The waterproof rubber ring between the lens and the step keeps the LED light source in a sealed state, and the use of a waterproof terminal at the end of the electric wire prevents water or water mist from entering the downlight in a humid environment. This provides excellent waterproof performance and meets the needs of use in humid indoor and outdoor environments.

[0023] like Figures 1 to 5 As shown, this embodiment provides a waterproof downlight, including a lamp housing 1. A deep groove 101 is provided on one side of the lamp housing 1. An LED light source is installed in the deep groove 101, illuminating the outside of the groove. A step 11 is provided within the deep groove 101, surrounding the LED light source. A lens 2 is installed on the step 11, allowing the LED light source to illuminate the lens 2 for better light efficiency. A waterproof rubber ring 3 is provided between the lens 2 and the step 11, serving a waterproof function. A through hole 102 is provided within the deep groove 101. The LED light source is connected to a wire that extends out of the through hole 102. The LED light source is connected to an external power source. A waterproof terminal 4 is installed on the through hole 102. The waterproof terminal 4 can play a waterproof role, preventing water from entering the deep groove. The wire passes through the waterproof terminal 4 and is fixed. A waterproof rubber ring 3 is set between the lens 2 and the step 11 to keep the LED light source in a sealed state. The wire end uses the waterproof terminal 4. In this way, water or water mist cannot enter the downlight in a humid environment. It has excellent waterproof performance and meets the use requirements of indoor and outdoor humid environments.

[0024] Preferably, the lens 2 has an edge 21 on its periphery, which serves as a mounting edge. Screws are installed on the edge 21, and the screws pass through the edge 21 to connect and fix it to the step 11.

[0025] Preferably, the lens 2 is provided with a lamp cup 5, which is fixed to the inside of the lamp housing 1. The lamp cup 5 is fastened to the lamp housing 1, and the fastening method facilitates installation and disassembly, allowing for different colored lamp cups 5.

[0026] Preferably, a plurality of heat dissipation strips 103 are provided at the top of the lamp housing 1. The heat dissipation strips 103 can play a role in heat dissipation. The heat emitted during the operation of the LED light source is transferred to the heat dissipation strips 103 of the lamp housing 1 for dissipation, thereby improving the service life of the LED light source.

[0027] Preferably, spring clips 6 are installed on both sides of the lamp housing 1, and the spring clips 6 are used to install the downlight on the ceiling.

[0028] Existing downlights are relatively weak in protection against humid weather, such as during the spring rain season. Moisture can easily penetrate from the front or rear of the lamp body, affecting the stability of its lighting performance. Therefore, a waterproof downlight is provided. A step 11 is set in the deep groove 101 of the lamp housing 1, and the step 11 surrounds the LED light source. A lens 2 is installed on the step 11, and a waterproof rubber ring 3 is set between the lens 2 and the step 11. Furthermore, a waterproof terminal 4 passes through the outside of the lamp housing 1. In this way, water or water mist cannot enter the downlight in a humid environment, resulting in excellent waterproof performance and meeting the needs of use in humid indoor and outdoor environments.

[0029] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
