A kind of LED lamp and lamp plate wherein
Technical field
The present invention relates to a kind of for the LED lamp that throws light on and lamp plate wherein.
Background technology
As shown in Figure 4, Figure 5, traditional LED lamp, no matter be shot-light or bulb lamp, its structure generally includes: lamp holder and be arranged on the side lamp cover on lamp holder, the top of side lamp cover is provided with top lampshade, on side lamp cover, along circumferentially offering several louvres, on described lamp holder, be provided with cooling fan and the LED lamp plate that is positioned at cooling fan below.Because this traditional LED lamp has adopted initiatively forced heat radiation structure, that is: be provided with cooling fan, thereby increased manufacturing cost, and, under normal circumstances, the service life of cooling fan is all shorter with respect to lamp plate, thereby has affected the service life of whole LED lamp; In addition, owing to having offered louvre, can not prevent dust, further have influence on the service life of cooling fan; In addition, due to current lamp plate, its circuit board all can not be reeled, and therefore, conventionally all lamp plate is directly installed on lamp holder, and light, directly to external exposure, makes light more dazzling, not soft.
Summary of the invention
Technical problem to be solved by this invention is: a kind of LED lamp plate that can be arranged to according to actual needs various shapes is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of LED lamp plate, comprising: several LED lamp pearls, several described LED lamp pearls are arranged on the mantle circuit of sector shape.
Several described LED lamp pearls are distributed on several concentric circular arcs.
The quantity of the LED lamp pearl distributing on every circular arc all equates.
On all circular arcs, corresponding LED lamp pearl connects in line, and the extended line of all straight lines intersects at same point.
On the back side of described mantle circuit, be provided with insulating medium layer.
Another technical problem to be solved by this invention is: provide a kind of can natural heat dissipation, and can improve radiation response, make the LED lamp that its light is softer.
For solving another above-mentioned technical problem, the technical solution used in the present invention is: a kind of LED lamp, comprise: lamp holder, on lamp holder, be provided with side lamp cover, the top of side lamp cover is provided with top lampshade, on the inwall of described side lamp cover, be provided with heat pipe, on the inwall of heat pipe, be provided with by lamp plate of the present invention reel the lamp cylinder surrounding and the lens that match with a corresponding side ports of lamp cylinder.
The surface, medial and lateral of described side lamp cover is parabola, answers in contrast, and the surface, medial and lateral of described heat pipe is also parabola.
Described lamp holder is sped structure.
Described lamp cylinder is directly fitted with heat pipe high temperature by the insulating medium layer that is arranged on its bottom surface.
The invention has the beneficial effects as follows: LED lamp plate of the present invention can be arranged to various shapes according to actual needs, thereby greatly widened its application scenario; LED lamp of the present invention is owing to having adopted heat pipe as heat dissipation element, that is: the heat that LED lamp pearl produces outwards dispels the heat by heat pipe, no longer needs cooling fan, thereby greatly reduces manufacturing cost, has extended service life; This LED lamp is by arranging lens and by the LED lamp plate of the said structure lamp cylinder forming of reeling, and makes the mode of the light scioptics refraction that LED lamp pearl occurs to external exposure, greatly improved the soften of light.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As shown in Figure 3, a kind of LED lamp plate of the present invention, comprise: several LED lamp pearls 6, these several LED lamp pearls 6 are arranged on the mantle circuit 5 of sector shape, the mantle circuit 5 here refers to the mantle that is provided with circuit, on the back side of mantle circuit 5, be provided with insulating medium layer (belonging to conventional design, not shown); In the present embodiment, several LED lamp pearls 6 are distributed on two concentric circular arcs; And the quantity of the LED lamp pearl 6 distributing on every circular arc is all equal, on two circular arcs, corresponding LED lamp pearl 6 connects in line, and the extended line of all straight lines intersects at the i.e. center of circle O of two isocentric circular arc of same point; Between described lamp holder 1, side lamp cover 2 and heat pipe 4, be also provided with the placing chamber 9 of the circuit board for driving LED lamp plate is installed.
As shown in Figure 1 and Figure 2, a kind of LED lamp of the present invention, comprise: the lamp holder 1 of helical structure, on lamp holder 1, be provided with its surface, medial and lateral and be paraboloidal side lamp cover 2, the top of side lamp cover 2 is provided with top lampshade 3, on the inwall of described side lamp cover 2, be provided with its surface, medial and lateral and be paraboloidal heat pipe 4, on the inwall of heat pipe 4, high temperature is fitted with LED lamp plate as shown in Figure 3 reel the lamp cylinder 7 (heat pipe 4 fits together with the insulating medium layer on mantle circuit 5 bottom surfaces) surrounding and the lens 8 that match with a corresponding side ports of lamp cylinder 7.
Shown in Figure 2, this LED lamp in use, the light that the LED lamp pearl 6 on lamp cylinder 7 sends, after lens 8 refractions, to external exposure, greatly improve the soften of light by top lampshade 3, avoided the dazzling phenomenon directly causing to external exposure because of the light that LED lamp pearl 6 sends.
Above-described embodiment does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
