With the development of society, people also need to consider energy saving and environmental protection while improving their living and working environment. The LED floodlights currently on the market are a good example. The following disadvantages exist in the existing LED floodlights: the lamp shell of the existing LED floodlight is made of plastic or thin iron sheet, and the service life is short; while the service life of the LED is much higher than the life of the lamp shell, That is, the service life of the lamp housing and the LED does not match, which reduces the service life of the lamp; in addition, in the prior art, the common LED floodlights are all square or channel-shaped structures, and the angle of light emitted during use is not square. Regular, there are problems such as inconsistent light and shade; in addition, because the tempered glass is a plane, the heat dissipation surface is small and the heat dissipation itself is not good, which affects the service life of the lamp.

In response to the above problems, there has been a Chinese patent No. "CN2767822", named: "A circular high-power LED floodlight", which includes a bottom basin, an installation seat cover, and an installation seat cover at the rear of the installation seat cover. There is a power control box inside the installation seat cover, a bracket is fixed on the front of the installation seat cover, the two ends of the bracket are connected with the side wall of the bottom basin, and a power board is installed on the top of the bottom basin, and a high-power LED light is installed on the power board . This circular high-power LED floodlight has a thick base, good anti-theft performance and improved service life. However, due to the large thickness of the base, its heat dissipation performance is poor, which also affects the service life of the floodlight. .

At present, there is no better implementation manner to solve the above problems.

The technical scheme adopted by the utility model is: a circular LED spotlight lamp, including a lamp housing and a lamp cover, which is characterized in that: the lamp housing and the lamp cover are connected to form a sealed cavity, and a set of For an LED lamp, a group of mutually parallel concave cooling ring grooves are evenly formed on the outer wall of the lamp housing. By arranging a group of parallel concave cooling ring grooves with the same spacing on the outer wall of the cylindrical lamp housing, the heat dissipation area is increased, the overall heat dissipation of the lamp is improved, and the service life of the lamp is extended.

The inner top of the lamp housing is provided with an aluminum substrate, and a group of LED lamps are uniformly distributed on the aluminum substrate, and the LED lamps include LED particles and an optical lens arranged directly above the LED particles.

Several DC to DC constant current drive chips electrically connected to the LED lamps are welded on the aluminum substrate, and the constant current drive chips are respectively arranged between the connected LED lamps; Stability, and improve the service life of LED lights.

The lamp cover is made of transparent plexiglass, and a layer of shading plate is arranged on the inner surface of the lamp cover, and the edge of the shading plate is closely connected with the periphery of the lamp housing. By setting the shading plate, the light absorption of the pure aluminum material can be effectively avoided, and the light output rate of the floodlight is increased.

A group of through holes corresponding to the LED lamps are arranged on the light shielding plate, and the upper edge of the optical lens is fixed on the wall of the through hole.

A waterproof sealing ring is also provided on the contact surface between the lamp cover and the lamp housing. Rain and snow are often encountered during actual use, and the waterproof sealing ring can effectively prevent rainwater from entering the interior of the lamp and affecting its service life.

A waterproof nylon box holder with wires is installed at the center of the bottom of the lamp housing, and the waterproof nylon box holder can be purchased. A set of mounting holes is also provided on the outer ring at the bottom center of the lamp housing.

The lamp housing is made of pure aluminum material, and the aluminum lamp housing not only improves the heat dissipation of the lamp, but also increases the service life of the lamp.

The beneficial effects of the utility model are as follows: 1. By setting up a group of concave cooling ring grooves parallel to each other and with the same spacing on the outer wall of the lamp housing, the heat dissipation area is increased, the overall heat dissipation of the lamp is improved, and the service life of the lamp is extended; At the same time, the volume of the lamp under the same heat dissipation area is reduced, making the overall lamp more compact and reducing the cost; 2. The lamp shell is made of pure aluminum material, which further improves the heat dissipation of the floodlight; 3. There is a layer on the inner side of the lamp cover The shading plate can effectively prevent the pure aluminum material from absorbing light and increase the light output rate; 4. It is designed in a disc-shaped structure, which can make the light emitted from the floodlight more regular and uniform.
