Background technique

With the continuous development of science and technology, LED lights have also improved, and the lights used in different places are also different. In the field of lighting, the technical requirements for the light source part should not only dissipate heat smoothly, but also prevent the light inside the lamp body from leaking out of the lamp body, so as to cause pollution to the light in the use place. The heat dissipation effect of traditional lighting fixtures is not ideal, resulting in high energy consumption, inconvenient assembly, high production cost, low safety and reliability, poor heat dissipation effect, and it is easy to cause the light in the lamp body to directly shine or diffuse out of the lamp body. It is difficult to form a visual appeal in appearance.

The photocontroller is installed above the radiator.

Two symmetrically arranged reinforcing plates are welded between the mounting base and the light source mounting plate in the above technical solution.

In the above technical solution, a timer is also installed in the lamp housing; the output end of the timer is connected to the input end of the light controller.

After adopting the above technical scheme, the utility model has the following positive effects:

(1) A fan is installed at the center of the top of the lamp housing of the utility model. By starting the fan and cooperating with the staggered inner and outer heat sinks, the airflow velocity inside the lamp housing is accelerated, thereby taking away the heat in the lamp housing more quickly .

(2) The utility model controls the safety light through the light controller, which is convenient and fast, and realizes the adjustable function of the light.

(3) The installation seat of the utility model is connected with a fixed bracket through fasteners, which facilitates the installation of the lamp, and has a reinforcing plate to increase the strength of the lamp.

(4) A timer is also installed in the lamp housing of the present utility model; the timer is connected with the light controller, and the switch of the fan can be independently controlled by starting the timer, which can save energy and ensure the heat dissipation effect in the lamp housing at the same time good.
