Abstract
The invention discloses an LED bulb lamp with high lighting efficiency. According to the invention, a flat PCB (Printed Circuit Board) is changed into a tower-shaped PCB, an LED at the center of the tower-shaped PCB is closer to a frosted lamp cover as comparison with the LED in the traditional flat structure, thus, the surface illuminance attenuation of the LED bulb lamp is less, the brightness of the LED bulb lamp is increased by 10-20%, and the LED bulb lamp is larger in light emitting angle and more uniform in light emitting; in addition, the tower-shaped structure ensures that the inside of the lamp is larger, heat generated at a circuit part is easier to radiate, and the stability of a product is improved.
Description
Technical field
The present invention relates to the LED bulb lamp of a kind of bulb lamp, particularly a kind of high light efficiency.
Background technology
Along with the popularization of energy-saving and emission-reduction policy, the LED illumination also is one of them direction, and its structure generally is the LED that on the pcb board on a plane, burn-ons, and overlaps upper lamp shade (as shown in Figure 2) again.But the LED of normal transparent lampshade does not more and more receive people's attention, change the frosted lampshade into after, the top of conventional planar PCB centre distance frosted lampshade farthest, the light loss of LED is more serious.According to principles well-known: surperficial illumination equals initial illumination square can know by inference divided by centre distance; Distance is far away more, and surperficial illumination decay is big more, particularly the center of ball bubble; The brightness ratio edge is low; Its distribution curve flux forms the curve of an indent, thereby band caused problems such as brightness is not enough, lighting angle is little, light is inhomogeneous, does not reach the standard of lighting of home.
Summary of the invention
In order to overcome the deficiency of prior art, the present invention provides that a kind of luminosity is higher, lighting angle is bigger, luminous uniform LED light-emitting device.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of LED bulb lamp of high light efficiency comprises radiator and elen shade, it is characterized in that: said radiator is provided with the turriform pcb board, and the turriform pcb board is provided with LED lamp pearl.
Said turriform pcb board comprises that ground floor, the second layer and the 3rd layer, said LED lamp pearl are arranged at respectively on ground floor, the second layer and the 3rd layer.
Said LED lamp pearl evenly distributes on each layer of turriform pcb board.
The invention has the beneficial effects as follows: the present invention is through changing the pcb board on plane into the turriform pcb board; Compare old slab construction; The distance of turriform pcb board center LED and frosted lampshade is nearer, thereby its surperficial illumination decay is less, makes the brightness of LED bulb lamp that the lifting of 10-20% arranged; And lighting angle is bigger, and is luminous more even; In addition, pyramidal structure makes lamp interior bigger, and the heat that circuit part produces is more prone to distribute, and increases the stability of product.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is a generalized section of the present invention;
Fig. 2 is the generalized section of old structure.
The specific embodiment
With reference to Fig. 1, the invention discloses a kind of LED bulb lamp of high light efficiency, comprise radiator 1 and elen shade 2, said radiator 1 is provided with the turriform pcb board, and the turriform pcb board is provided with LED lamp pearl 3.
As shown in the figure; In this specific embodiment, this turriform pcb board comprises ground floor 4, the second layer 5 and the 3rd layer, and ground floor 4, the second layer 5 and the 3rd layer of 6 round platform that reduces successively for diameter also are disposed in order the formation turriform; Said LED lamp pearl 3 is arranged at respectively on ground floor 4, the second layer 5 and the 3rd layer 6; Certainly above-mentioned is a specific embodiments of the present invention, and paired inadequately restriction of the present invention, and the turriform pcb board of this structure also can be designed as four layers or two-layer isostructural turriform; And each layer of turriform is not limited to roundly, also can be polygons such as regular hexagon or regular pentagon.
For more even light emission, LED lamp pearl 3 evenly distributes on each layer of turriform pcb board.Lampshade of the present invention is an elen shade 2, and elen shade 2 can be effectively reduces the string light of LED, to eliminate the injury of LED lamp high light to human eye.
Above-mentionedly just preferred embodiments more of the present invention are illustrated and describe, but embodiment of the present invention is not restricted to the described embodiments,, all should belong to protection scope of the present invention as long as it reaches technique effect of the present invention with essentially identical means.
