The utility model relates to a light-emitting diode (LED) lamp emanating wheel-shaped light. The LED lamp emanating wheel-shaped light comprises a heat dissipation body, a lamp head and a lamp cover. The heat dissipation body is connected above the lamp head. The lamp cover is connected above the heat dissipation body. A baffle ring is arranged on the position where the lamp cover is connected with the heat dissipation body. A plurality of heat dissipation walls which are distributed along the periphery direction of the heat dissipation body are arranged on the outer side of the heat dissipation body. A base is arranged on the interior of the heat dissipation body. A plurality of LED light beads are arranged on the outer surface of the base. The lamp head is in electric connection with a drive element. The drive element controls opening and closing of each LED lamp bead. The heat dissipation body is made of transparent or semitransparent materials. The baffle ring and the heat dissipation walls are respectively made of light tight materials. The LED lamp emanating wheel-shaped light is attractive in structure, emanates light-shade-alternative light rays through a structure of the heat dissipation body and change of material light-admitting quality, and the wheel-shaped and light-shade-alternative light rays which have gradual change effect and art feeling are projected on a medium on the back side of a lamp light source.

Description

A kind of LED lamp that sends wheel shape light

Technical field

The utility model relates to a kind of LED lamp, and the LED lamp that sends wheel shape light that particularly a kind of structure is attractive in appearance, light effects is attractive in appearance belongs to LED illumination part technical field.

Background technology

The LED lamp is as a kind of emerging lighting source, and it is little to have a volume, and the advantages such as energy consumption is low, luminous intensity is high, long environmental protection of life-span have outstanding energy-saving effect, are a kind of green light sources.But because the work such as LED are the electric energy that consumes, a part is converted into the luminous energy of high brightness, major part then can change into heat energy, so the LED lantern festival produces a large amount of heats, and if this part heat is untimely distributes, when surpassing certain value, serious decay can appear in LED lamp luminous intensity and life-span, even causing permanent damage, this has just shortened the service life of LED lamp greatly, so the LED lamp must have good radiator structure; And along with social progress, improving constantly of living standard, people have had higher requirement for light and the light effects of household or public place, therefore, it is attractive in appearance to design some structures, and the LED lamp that the light that especially sends has artistic effect just seems necessary.

The utility model content

The utility model purpose is that the LED lamp that sends wheel shape light that a kind of structure is attractive in appearance, light effects is attractive in appearance is provided in order to overcome the deficiencies in the prior art.

For achieving the above object, the technical solution adopted in the utility model is: a kind of LED lamp that sends wheel shape light comprises radiator, lamp holder, lampshade; Described radiator is connected to the top of lamp holder; Described lampshade is connected to the top of radiator; The junction of described lampshade and radiator is provided with baffle ring; The arranged outside of described radiator has a plurality of heat radiation walls that circumferentially distribute around radiator; The inside of described radiator is provided with pedestal, is provided with a plurality of LED lamp pearls on the outer surface of pedestal; Described lamp holder is electrically connected with driving element; Described driving element is controlled the unlatching of each LED lamp pearl or is closed; Described radiator is transparent or semitransparent material; Described baffle ring is light-proof material with the heat radiation wall.

Preferably, the top of described pedestal is provided with central seat, and sidepiece is provided with inclined base; Described central seat is horizontally disposed with; Described inclined base is upper surface being obliquely installed outwardly around the excircle of central seat.

Preferably, the upper surface of described central seat exceeds baffle ring; Described inclined base is arranged on the position at radiator middle part.

Preferably, described pedestal is the hemisphere that arc surface makes progress.

Preferably, described a plurality of LED lamp pearl is evenly distributed on the outer surface of pedestal.

Because the utilization of technique scheme, the utility model compared with prior art has following advantages:

The LED modulated structure that sends wheel shape light of the utility model scheme is attractive in appearance, and send light and dark light by the structure of radiator portion and the variation of material light transmission, can be on the medium at the lamp source back side projection go out the wheel shape, light and dark, with the light with artistic feeling of fade effect.

Description of drawings

Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Accompanying drawing 1 is the front view that sends the LED lamp of wheel shape light described in the utility model;

Accompanying drawing 2 is the cutaway view that sends the LED lamp of wheel shape light described in the utility model;

Accompanying drawing 3 is the figure of LED lamp wiring drop shadow effect that sends wheel shape light described in the utility model;

Wherein: 1, radiator; 2, lamp holder; 3, lampshade; 4, baffle ring; 5, heat radiation wall; 6, pedestal; 7, driving element; 8, central seat; 9, inclined base; 10, dark Projection Division; 11, the dark Projection Division of annular; 12, grid Projection Division.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Accompanying drawing 1-2 is the LED lamp that sends wheel shape light described in the utility model, comprises radiator 1, lamp holder 2, lampshade 3; Described radiator 1 is connected to the top of lamp holder 2; Described lampshade 3 is connected to the top of radiator 1; Described lampshade 3 is provided with baffle ring 4 with the junction of radiator 1; The arranged outside of described radiator 1 has a plurality of heat radiation walls 5 around 1 one weeks of radiator; The inside of described radiator 1 is provided with central seat 8 and inclined base 9; Described central seat 8 is horizontally set on the center line of radiator 1, and the upper surface of central seat 8 exceeds baffle ring 4; Described inclined base 9 is arranged on the position at radiator 1 middle part, and is upper surface being obliquely installed outwardly around the center line of radiator 1; The upper surface of described central seat 8 and inclined base 9 is provided with equally distributed LED lamp pearl; Be electrically connected successively by driving element 7 between described central seat 8 and inclined base 9 and the lamp holder 2; Described radiator 1 is light transmissive material; Described baffle ring 4 is light-proof material with heat radiation wall 5.
