Abstract

The utility model relates to an LED illumination lamp comprising a lamp base and a lamp source, wherein the lamp source is arranged at the front end of the lamp base; the lamp source comprises a plurality of split lamp tubes; the plurality of lamp tubes are arranged to form a polygon surrounding the center of the circle; each lamp tube comprises LED beads, a circuit board, a radiator and a lampshade; the LED bead are arranged on the circuit board that is arranged on the radiator; the lampshade covers the circuit board and is connected with the radiator; and the lampshade is arranged on the radiator and covers the circuit board. In the utility model, the cylindrical lamp body structure is adopted, thus providing floodlight of more angles compared with the slab-type structure and increasing illumination scope; the radiator arranged behind the LED circuit board can effectively dissipate the heat generated by the LED, thus prolonging the service life of the LED; and the lamp body adopts the split lamp source structure so that the maintenance of the illumination lamp is more convenient and the replacement cost of the LED is reduced when individual LED is damaged.

Description

The LED illuminating lamp

Technical field

The utility model relates to a kind of LED light-emitting device, relates in particular to a kind of LED illuminating lamp.

Background technology

Development along with lighting engineering, LED begins to appear at various occasions as a kind of new illuminating product, LED compares the traditional lighting lamp, and advantages such as brightness height, power consumption is low, caloric value is little, the life-span is long are arranged, and it is present main direction of studying that LED is applied to normal lighting.

Existing LED illuminating lamp is that the number LEDs is placed on the circuit board, to reach predetermined illuminating effect.Present led circuit plate all is dull and stereotyped style, and plurality of LEDs lamp pearl is set on the circuit board, and flat its illumination of LED illuminating lamp of this kind is penetrated direction in the zone of an angle, and the floodlighting of multi-angle can not be provided; The problem of present in addition LED illuminating lamp ubiquity radiating effect difference, the heat that LED sends can not well distribute, and has a strong impact on the service life of LED.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, and a kind of multi-angle floodlighting and good LED illuminating lamp of radiating effect with combined radiator is provided.

For achieving the above object, the utility model adopts a kind of LED illuminating lamp, comprise lamp holder and light source, light source is arranged on the lamp holder front end, and light source is made of the fluorescent tube of many split settings, many fluorescent tubes are arranged to center on the polygon in the center of circle, fluorescent tube comprises LED lamp pearl, circuit board, radiator, lampshade, and LED lamp pearl is arranged on the circuit board, and circuit board is arranged on the radiator, lampshade covers circuit board and is connected with radiator, and lampshade is arranged on the radiator and covers circuit board.

The utility model has adopted columniform lamp body structure compared to existing technology, and flat relatively structure can provide the floodlighting of more perspective, has increased illumination zone, has remedied traditional LED light fixture rising angle defect of insufficient; The heat that the radiator that adds behind the led circuit plate can effectively produce LED scatters and disappears away, has increased the life-span of LED and the stability of light fixture; Lamp body has adopted the light-source structure of split, makes the illuminating lamp maintenance convenient, has also reduced to change under the situation that indivedual LED damage the cost of LED.

The radiator of described fluorescent tube is that the cross section is to be inverted trapezoidal cylinder, trapezoidal bottom surface is that circuit board is provided with end, one end of trapezoidal upper bottom surface is formed with the circular chute of opening, the other end form one with the suitable circular draw runner of circular chute, each radiator forms to locate with the concentric stroking bar by corresponding circular draw-in groove on self circular draw-in groove and circular draw runner and the adjacent radiator and cooperates fixedlying connected between the formation fluorescent tube.

Described lampshade is an arc, and the arc inward at both ends extends to form card article; The bottom surface of described radiator forms two draw-in grooves that cooperate with the lampshade card article.

The specific embodiment

As Figure 1-3, specific embodiment of the utility model is a kind of LED illuminating lamp, comprise lamp holder 2 and lamp source, the lamp source is arranged on lamp holder 2 front ends, the lamp source is arranged to regular pentagon by five fluorescent tubes 1 around a center of circle, each fluorescent tube 1 comprises LED lamp pearl 11, circuit board 12, radiator 13, lampshade 14, seven LED lamp pearls 11 are arranged on the circuit board 122, circuit board 12 is arranged on the radiator 13, lampshade 14 is an arc, cover on the circuit board 12 and be connected with radiator 13, there is the card article 19 of inside extension at the edge of lampshade 14, have on the radiator 13 with lampshade on the suitable draw-in groove 110 of card article 19, card article 19 can slip into from radiator 13 1 ends and realize in the draw-in groove 110 connecting, as long as skid off during dismounting, radiator 13 structures are that the cross section is trapezoidal cylinder, trapezoidal bottom surface 15 is provided with end for circuit board, trapezoidal upper bottom surface 16 1 ends are formed with the circular chute 18 of opening, the other end forms with circular chute thinks adaptive circular draw runner 17, relying on circular draw runner 17 on each radiator to slip into circular chute 18 on the adjacent radiator between five fluorescent tubes forms the location and cooperates and constitute fixedly connected between fluorescent tubes, five fluorescent tubes 1 connect into the outside regular pentagon of lampshade 14, make lighting angle enough big.

The fluorescent tube of the utility model LED illuminating lamp not only is confined to five of above-mentioned specific embodiment; The LED lamp pearl that is arranged in a circuit board also not only is confined to seven of the foregoing description, and fluorescent tube and LED lamp pearl all can increase or reduce setting according to the concrete application of product.
