The technical solution adopted in the utility model is: a kind of round LED Projecting Lamp, comprise lamp housing and light cover, it is characterized in that: described lamp housing is connected the back and forms sealed cavity with light cover, be provided with one group of LED lamp in the cavity, evenly be shaped on one group of concave shaped heat radiation ring recess that is parallel to each other on the outer wall of described lamp housing.By one group of parallel, that spacing is identical concave shaped heat radiation ring recess is set on the outer wall of cylindrical lamp housing, increase area of dissipation, improve the thermal diffusivity of light fixture integral body, thereby prolong the service life of light fixture.

Described lamp housing inner top is provided with aluminium base, and the one group of LED lamp that evenly distributes on the aluminium base, described LED lamp comprise the LED particle and be arranged on optical lens directly over the LED particle.

Be welded with the constant-current driven chip of several DC to DC that are electrically connected with the LED lamp on the described aluminium base, this constant-current driven chip is separately positioned on and links to each other between the LED lamp; By being set, constant-current driven chip not only increased the stability of LED lamp and the service life of improving the LED lamp.

Described light cover is made of transparent lucite, and the medial surface of light cover is provided with one deck shadow shield, the peripheral driving fit mutually of the edge of described shadow shield and lamp housing.Can avoid the pure aluminum material extinction effectively by shadow shield is set, increase the light emission rate of Projecting Lamp.

Described shadow shield be provided with one group with LED lamp through hole one to one, the upper limb of optical lens is fixed on the hole wall of through hole.

Also be provided with waterproof grommet on described light cover and the lamp housing contact-making surface.When reality is used, run into sleety weather, can prevent effectively that by waterproof grommet is set rainwater from entering lamp interior and influencing its service life through regular meeting.

A waterproof nylon box holder head that is provided with lead, this waterproof nylon box holder buyable are installed by described lamp housing bottom centre.The bottom centre outer ring of lamp housing also is provided with one group of installing hole.

Described lamp housing is made by pure aluminum material, adopts the aluminum lamp housing, has not only improved the thermal diffusivity of light fixture, and has improved the service life of light fixture.

The beneficial effects of the utility model are: 1, are parallel to each other by on the lamp housing outer wall, offering one group, and the concave shaped heat radiation ring recess that spacing is identical, thus increase area of dissipation, improve the thermal diffusivity of light fixture integral body, prolong the service life of light fixture; Dwindle the volume of light fixture under the identical area of dissipation simultaneously, made that light fixture integral body is smaller and more exquisite, reduced cost; 2, adopt pure aluminum material to prepare lamp housing, further improved the thermal diffusivity of Projecting Lamp; 3, the light cover medial surface is provided with one deck shadow shield, can effectively avoid the pure aluminum material extinction, has increased light emission rate; 4, be designed to disc-shaped structure, can make the light of from Projecting Lamp, getting regular more and even.
