The specific embodiment
It will be appreciated by those skilled in the art that those skilled in the art can realize variation example in conjunction with prior art and above-described embodiment, do not repeat them here.Such variation example does not affect flesh and blood of the present invention, does not repeat them here.
Fig. 1 illustrates according to a specific embodiment of the present invention, the explosive view of full light-distribution LED bulb lamp of the present invention.As shown in Figure 1, the invention provides a kind of full light-distribution LED bulb lamp, comprising: lamp holder 101, connecting piece of lamp cap 201, driving power 301, radiator 401, LED light emitting module 501, reflecting layer 601 and lampshade 701.Lamp holder 101 is connected on connecting piece of lamp cap 201, and connecting piece of lamp cap 201 is connected to radiator 401 first ends, and LED light emitting module 501 is connected to radiator 401 second ends.Driving power 301 is arranged in connecting piece of lamp cap 201, and driving power 301 is controlled the duty of LED light emitting module 501.Lampshade 701 is connected on the inclined-plane 402 of radiator 401 second ends.LED light emitting module 501 by cover cap in lampshade 701.Reflecting layer 601 is arranged in lampshade 701.Reflecting layer 601 be shaped as flared structure.Tubaeform outer wall is provided with ring-shaped depression region 602.As required, reflecting layer 601 can be to be also semi-transparent reflection layer, to adjust the light intensity on the different direction of illuminations of full light-distribution LED bulb lamp.Select within the materials such as glass, light-passing plastic drop on protection scope of the present invention equally as reflecting layer.Reflecting layer 601 in the present embodiment is resistant to elevated temperatures reflecting paper, or semi permeability reflecting paper.
Fig. 2 illustrates according to a specific embodiment of the present invention, the cutaway view of full light-distribution LED bulb lamp of the present invention.As shown in Figure 2, lamp holder 101 is tightened on connecting piece of lamp cap 201.Driving power 301 is arranged in the cavity of connecting piece of lamp cap 201.The first end of radiator 401 is socketed on connecting piece of lamp cap 201 outer walls, the second end fixed L ED light emitting module (referring to the Reference numeral 501 in Fig. 1) of radiator 401.Lampshade 701 is fixed on the inclined-plane 402 of radiator 401 second ends.
LED light emitting module (referring to the Reference numeral 501 in Fig. 1) is a planar LED illuminating circuit, is convenient to mounted LED lamp bulb, cost also lower than in prior art on three-dimensional stem stem the mode of paster LED lamp pearl.LED light emitting module comprises printed circuit board 502 and is arranged on the LED luminescence chip 503,504 on printed circuit board 502.Reflecting paper contact LED light emitting module, by the light source on LED light emitting module, is divided into the LED luminescence chip 503 around that is positioned at by ectocentral LED luminescence chip 504 and corresponding reflecting paper outer wall of corresponding reflecting paper inwall.The present invention mainly adjusts the light path of script LED lamp pearl in one plane by the special shape of reflecting paper.Printed circuit board 502 held against heat sink 401.And printed circuit board 502 be take aluminium as base material, so that transmit heat to fast radiator 401.
In the present embodiment, the shape of reflecting paper is preferably flared structure.This structure has great help for reflection ray.The upper end of reflecting paper extends out, and lower end is towards LED light emitting module 501.Reflecting paper can near or contact LED light emitting module 501, can determine according to the actual requirements.Between reflecting paper and LED light emitting module 501, retain some distance and contribute to prevent that reflecting paper is heated, the hidden danger of avoiding reflecting paper to burn under long-time high temperature.
Wherein a part of LED luminescence chip 504 is positioned at the ring that reflecting paper forms, and the light that this part LED luminescence chip 504 sends upwards; Another part LED luminescence chip 503 is positioned at outside the ring of reflecting paper formation, and the light that this part LED luminescence chip 503 sends is downward through the effect of reflecting paper.
By the light of ectocentral LED luminescence chip 504, be subject to the reflection of reflecting paper inwall, the change of reflection angle is less, so light is distributed in by direct projection and reflecting paper reflection by ectocentral LED luminescence chip 504 in the region of 0 ° to 90 °.
The light that is looped around LED luminescence chip 503 is around subject to the reflection of reflecting paper outer wall, light is radiated at after the tubaeform outer wall of reflecting paper, by reflection, change light path, reflection angle improves greatly, so be looped around in LED luminescence chip 503 is around reflected in 180 ° to 270 ° region by reflecting layer 601.
Reflection angle for further spread reflection paper, ring-shaped depression region 602 can be set on the outer wall of reflecting paper, and the light of the LED light emitting source 503 in LED light emitting module (referring to the Reference numeral 501 in Fig. 1) is radiated at the rear increase reflection angle of sunk area 602.Easily expect, sunk area 602 can be for circular arc caves in, or the sunk area 602 being comprised of several continuously arranged toroidal reflective surface.From in shape reflecting paper being changed, make within its structure that increases reflection angle drops on protection scope of the present invention equally.
In order further to strengthen the heat dispersion of radiator 401, on radiator 401, be provided with some radiating fins, so that accelerate heat, disperse.
Fig. 3 illustrates according to a specific embodiment of the present invention, the use state light path schematic diagram of full light-distribution LED bulb lamp of the present invention.As shown in Figure 3, LED light emitting module (referring to the Reference numeral 501 in Fig. 1) when work, be positioned at light that the LED luminescence chip 504 of the ring that reflecting paper forms sends upwards (its light path is referring to Reference numeral A).Be positioned at light that the LED luminescence chip 503 outside the ring that reflecting paper forms sends through the effect of reflecting paper (its light path is referring to Reference numeral B) downwards.
Specifically, by the light of ectocentral LED luminescence chip (referring to the Reference numeral 504 in Fig. 2), be subject to the reflection of reflecting paper inwall, the change of reflection angle is less, so light is distributed in by the reflection of direct projection and reflecting paper by ectocentral LED luminescence chip in the region of 0 ° to 90 °.The light that is looped around LED luminescence chip (referring to the Reference numeral 503 in Fig. 2) is around subject to the reflection of reflecting paper inwall, light is radiated at after the tubaeform outer wall of reflecting paper, by reflection, change light path, reflection angle improves greatly, thus be looped around LED luminescence chip around by reflective layer reflects in the region of 180 ° to 270 °.
In summary, full light-distribution LED bulb lamp of the present invention has solved the less problem of lighting angle, avoid using mixed light cell-shell, by the reflecting layer of special construction is set in lampshade, the part light of LED light emitting module is carried out to the reflection of wide-angle, thereby greatly improved the lighting angle of bulb lamp integral body, and do not need a large amount of LED lamp pearls, simple in structure, work caloric value is low, long service life.
Above specific embodiments of the invention are described.It will be appreciated that, the present invention is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or modification within the scope of the claims, and this does not affect flesh and blood of the present invention.
