Abstract
The utility model provides a novel high-efficiency cooling LED bulb which comprises a transparent lampshade and a lamp cap mutually connected. A plurality of LEDs are arranged in the lampshade. The novel high-efficiency cooling LED bulb is characterized in that the transparent lampshade is also provided with a polyhedron connected with the lamp cap, and the plurality of LEDs are distributed on all the surfaces of the polyhedron so that the light-emitting surfaces of the plurality of LEDs face to different directions. In the utility model, the plurality of LEDs are arranged through the polyhedron, the light-emitting surfaces of all the LEDs face different directions to enlarge the light-emitting surfaces of the whole bulb, and the heat of the LEDs can be transferred to the lamp cap by the polyhedron and then emitted out by the lamp cap so that the cooling effect is effectively improved.
Description
[technical field]
The utility model relates to a kind of lighting apparatus, particularly a kind of new and effective cooling LED bulb.
[background technology]
Existing LED bulb has two kinds usually: first kind as shown in Figure 1, be the less LED bulb 1 ' of light-emitting area, it comprises a Transparent lamp shade 11 ' and a lamp holder 12 ', laterally be provided with a radiating block 13 ' in the Transparent lamp shade 11 ', one or more LED14 ' on the end face of this radiating block 13 ', have been sticked with glue, dispel the heat though the LED bulb 1 ' of this structure is established a radiating block 13 ', its light-emitting area is less, and its use is restricted.Second kind as shown in Figure 2, be the bigger LED bulb 1 of light-emitting area "; it comprises a Transparent lamp shade 11 " and a lamp holder 12 "; lamp body 11 " in vertically be provided with a heat-radiating rod 13 "; heat-radiating rod 13 " the side sticked with glue a plurality of LED14 ", make LED14 " light-emitting area towards having tow sides, thereby increased light-emitting area, but because heat-radiating rod 13 " with lamp holder between directly do not link to each other, radiating effect is weakened greatly.Therefore the structure of the LED bulb of above-mentioned two kinds of structures is all undesirable, need wait to improve.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of new and effective cooling LED bulb, makes radiating effect better, and light-emitting area is big.
The technical problems to be solved in the utility model is achieved in that a kind of new and effective cooling LED bulb, comprise an interconnective Transparent lamp shade and a lamp holder, establish a plurality of LED in the lampshade, it is characterized in that: described Transparent lamp shade also is provided with a polyhedron that is connected with lamp holder, described a plurality of LED is distributed on this polyhedral each surface, make these a plurality of LED light-emitting areas towards being not quite similar.
Described polyhedron is microscler column structure, and polyhedral free-ended end face edge has the LED of a plurality of annular distribution, and the light-emitting area of the LED of described annular distribution makes the light of each angle of polyhedron even all towards described polyhedral free end.
Described polyhedron and lamp holder are spirally connected, and make radiating effect better.
Also be connected a ceramic block between described lamp holder and the translucent cover, be used for auxiliary lamp holder heat radiation, make radiating effect better, it is applicable to the situation the when power of LED is big.
All be connected and fixed between described lamp holder, ceramic block and the translucent cover by heat transfer glue, so, heat on lamp holder and the ceramic block also can reach Transparent lamp shade with auxiliary heat dissipation by heat transfer glue, makes radiating effect better, and it is applicable to the situation the when power of LED is very big.
Advantage of the present utility model is: by a polyhedron a plurality of LED are set, make each LED light-emitting area towards being not quite similar, thereby make the light-emitting area of whole bulb become big; And polyhedron can reach lamp holder with the heat of LED, distributed by lamp holder again, and its radiating effect effectively improves.

[specific embodiment]
Embodiment one
See also Fig. 3 and shown in Figure 5, the new and effective cooling LED bulb 1 of present embodiment, comprise an interconnective Transparent lamp shade 11 and a lamp holder 12, be provided with a polyhedron 13 that is connected with lamp holder 12 in the described Transparent lamp shade 11, be bonded with a plurality of LED14 on each surface of described polyhedron 13, make these a plurality of LED14 light-emitting areas towards being not quite similar, thereby the light-emitting area that makes whole LED bulb 1 becomes big, polyhedron 13 is connected with lamp holder 12, polyhedron 13 can reach the heat of LED14 in lamp holder 12, is distributed by lamp holder 12 again, and its radiating effect effectively improves, if described polyhedron 13 is spirally connected with lamp holder 12, its radiating effect can be better.
Described polyhedron 13 is microscler column structure, and the end face edge of the free end 132 of polyhedron 13 relative links has the LED14 of a plurality of annular distribution, the light-emitting area of the LED14 of described annular distribution can make the light of polyhedron 13 each angle even all towards the free end 132 of described polyhedron 13.
Embodiment two
As shown in Figure 4, this embodiment two only is with the difference of embodiment one: also be connected a ceramic block 15 between described lamp holder 12 and the translucent cover 11, be used for auxiliary lamp holder 12 heat radiations, make radiating effect better, it is applicable to the situation the when power of LED14 is big.
Embodiment three
Still with reference to shown in Figure 4, the difference of this embodiment three and embodiment two only is: all be connected and fixed by heat transfer glue between described lamp holder 12, ceramic block 15 and the translucent cover 11 again, so, heat on lamp holder 12 and the ceramic block 15 also can reach Transparent lamp shade 11 with auxiliary heat dissipation by heat transfer glue, make radiating effect better, it is applicable to the situation the when power of LED14 is very big.
In sum, the utility model has the advantage of: by a polyhedron a plurality of LED are set, make each LED light-emitting area towards being not quite similar, thereby make the light-emitting area of whole bulb become big; And polyhedron can reach lamp holder with the heat of LED, distributed by lamp holder again, and its radiating effect effectively improves.
