Abstract

The utility model relates to the technical field of LED products, in particular to an LED lamp capable of expanding illumination range. The LED lamp comprises a lamp holder, a lampshade mounted on the lamp holder and an LED luminous body disposed in the lampshade, wherein a boss is molded on the lamp holder and the LED luminous body is arranged at the top end of the boss. As the boss is molded at the upper end of the lamp holder and the LED luminous body is mounted on the top surface of the boss, height of the LED luminous body is raised, an included angle between the horizontal level and a straight line formed by the center of the LED luminous body and the outer edges of the top of the lamp holder is increased, and then illuminating light of the LED luminous body can reach dark area which can not be irradiated by the existing LED lamps. Besides, the lamp holder comprises a plurality of radiating fins which are in outwards radial arrangement by utilizing the axis of the lamp holder as the center. The lamp holder with the structure can increase radiating efficiency greatly.

Description

A kind of LED light fixture

Technical field:

The utility model relates to the LED product technical field, is meant a kind of LED light fixture that enlarges illumination zone especially.

Background technology:

With respect to traditional lighting, the LED light fixture has following advantage:

1, energy-conservation.The energy consumption of white light LEDs only is 1/10 of an incandescent lamp, 1/4 of electricity-saving lamp.

2, long service life.The life-span of LED lamp can reach and be higher than incandescent lamp and electricity-saving lamp more than 100,000 hours far away.

3, can frequent starting.Very fast the breaking down if traditional electricity-saving lamp, frequent startup or the shutoff of incandescent lamp, filament will be turned black, and the LED lamp can not.

4, solid-state encapsulation belongs to the cold light source type, so its easily transportation and installing can be afraid of vibration by device in the equipment of any miniature and sealing, does not need to consider heat radiation basically.

5, environmental protection does not have the harmful substance of mercury.The very easily dismounting of the assembling parts of LED lamp, it is convenient to reclaim.

Based on These characteristics, the LED lamp will progressively replace other lightings.See Fig. 1, this is a LED light fixture, it comprises: lamp socket 11, illuminator 12, glass lamp shade 13 because the circuit heat of LED light fixture is higher, need to adopt heat abstractor, so the common volume of the lamp socket 11 that need dispel the heat is bigger, so just cause a problem, as shown in Figure 1, the angle a that straight line that illuminator 12 centers and lamp socket upper end-face edge form and horizontal plane constitute almost approaches zero degree, promptly this LED light fixture almost can't be shown up to the below of its lamp socket 11 end faces, forms the illumination dark space.

The utility model content:

Technical problem to be solved in the utility model for overcoming the existing deficiency of present LED light fixture product, proposes a kind of LED light fixture exactly, and this light fixture can effectively overcome the illumination dark space in the present LED light fixture, effectively enlarges the illumination zone of light fixture.

For solving the problems of the technologies described above, the utility model has adopted following technical scheme: this LED light fixture comprises lamp socket, be installed in lampshade on the lamp socket, be positioned at the LED illuminator of lampshade, form a boss on described lamp socket, described LED illuminator is positioned at the boss top.

Described lamp socket is the heat radiating metal body.

The lamp socket that described heat radiating metal system is done comprises most fin, and this fin is that the center outwards is the radiation divergent shape with the axis of lamp socket.

Described boss is a frustum of a cone.

The straight line that the edge shape of the center of described LED illuminator and lamp socket top outer rim forms and the angle of horizontal plane are greater than 45 °.

Form a boss in the lamp socket upper end in the utility model, the LED illuminator is installed in the boss end face, promptly raised the height of LED illuminator, so, make the angle increase of straight line that the edge shape of the center of LED illuminator and lamp socket top outer rim forms and horizontal plane, thereby make the illuminating ray of LED illuminator can arrive at the dark space that present LED light fixture can't shine.

Another aspect, the lamp socket among the present invention comprise most fin, and this fin is that the center outwards is the radiation divergent shape with the axis of lamp socket.Adopt the lamp socket of this structure can improve radiating efficiency greatly.

Description of drawings:

Fig. 1 is the structural representation of existing LED light fixture;

Fig. 2 is the schematic diagram of the utility model embodiment one;

Fig. 3 is the perspective view of the utility model embodiment two.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is elaborated.

See Fig. 2, present embodiment comprises: lamp socket 21, LED illuminator 22, glass lamp shade 23 and boss 24.Wherein, lamp socket 21 is the heat radiating metal body, so that the heat radiation of light fixture, lamp socket 21 is a cylinder in the present embodiment.Glass lamp shade 23 is installed on the lamp socket 21, and boss 24 is positioned at lamp socket 21 end face centers, and LED illuminator 22 is installed in boss 24 end faces.

Boss 24 is a frustum of a cone, and LED illuminator 22 is installed in boss 24 end faces, and the angle a of the straight line of edge shape 210 formation of the center of LED illuminator 22 and lamp socket 21 top outer rims and horizontal plane is greater than 45 °.So just make the illuminating ray of LED illuminator 22 can arrive at the dark space that present LED light fixture can't shine.

See Fig. 3, different is for present embodiment and the foregoing description.The lamp socket 21 that the heat radiating metal system is done in the lamp socket 21 in the present embodiment comprises most fin 211, and this fin 211 is that the center outwards is the radiation divergent shape with the axis of lamp socket 21.After lamp socket 21 adopts said structure in the present embodiment, because fin 211 can increase area of dissipation, so radiating effect is better.

Certainly, the above only is example of the utility model, be not to limit the utility model practical range, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
