Summary of the invention
In view of this, be necessary to provide a kind of structure simple and the Large-angle emission LED lamp of uniform-illumination.
A kind of Large-angle emission LED lamp, comprise bulb housing, light source board, LED light source and body, this light source board is arranged on the top of this body, this bulb housing is located at the top of this body, also comprise luminous intensity distribution ring, this luminous intensity distribution ring is the transparent body or translucent body, this luminous intensity distribution ring comprises madial wall and lateral wall, the bottom of this luminous intensity distribution ring is arranged on light source board top, described LED light source is located at light source board top around the lateral wall of this luminous intensity distribution ring, the part light that this lateral wall is used for this LED light source to send reflects along the direction of this body of deflection, the light that the described LED light source of part sends is by the top of this bulb housing of directive after the lateral wall of this luminous intensity distribution ring and madial wall refraction.
Compared with prior art, by arranging transparent or semitransparent luminous intensity distribution ring at light source board top, LED light source is located at light source board top around the lateral wall of this luminous intensity distribution ring, the part light that this lateral wall is used for this LED light source to send reflects along the direction of this body of deflection, and the light that the described LED light source of part sends is by the top of this bulb housing of directive after the lateral wall of this luminous intensity distribution ring and madial wall refraction.The irradiation of the uniform light that LED light source so just can be made to send, in the bottom of bulb housing and bottom, owing to eliminating the setting of heating column, flexible-belt, makes this LED have the simple and advantage of uniform-illumination of structure.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
Referring to Fig. 1 to 3, is the three-dimensional exploded view of the Large-angle emission LED lamp of first embodiment of the invention, comprises bulb housing 10, light source board 30, multiple LED light source 31, luminous intensity distribution ring 20, and body.This light source board 30 is arranged on the top of this body, the bottom surface of this light source board 30 and the end face of this body thermally coupled.The bottom of this luminous intensity distribution ring 20 is arranged on light source board 30 top.This bulb housing 10 is located at the top of this body.
This body comprises radiating piece 40 and lamp holder 50, the end face of radiating piece 40 and the bottom surface of light source board 10 thermally coupled, lamp holder 50 top is connected with bottom radiating piece 40.
This luminous intensity distribution ring 20 is the transparent body or translucent body, and this luminous intensity distribution ring 20 is horn-like shell structure, and its external diameter increases from the bottom of this luminous intensity distribution ring 20 gradually to top.This luminous intensity distribution ring 20 comprises madial wall and lateral wall, and the madial wall of this luminous intensity distribution ring 20 is provided with diffusing structure.This diffusing structure is the surperficial PC material through frosted process or PMMA material.Be provided with connector 21 bottom this luminous intensity distribution ring 20, light source board 30 is to being provided with through hole 32 by connector 21, and the connector 21 of described luminous intensity distribution ring 20 is connected with light source board 30 through this through hole 32.The light that the lateral wall of this luminous intensity distribution ring 20 is used for these LED light sources 31 to send reflects along the direction of this lamp holder 50 of deflection, and the light that part LED light source 31 sends is by the top of this bulb housing 10 of directive after the lateral wall of this luminous intensity distribution ring 20 and madial wall refraction.
This bulb housing 10 was hemisphere cell-shell.This bulb housing 10 is provided with printing opacity scattering material, and the wall thickness of this bulb housing 10 is thickening gradually to top by bottom, thickness even transition.Because this bulb housing 10 is provided with printing opacity scattering material, the thicker central light strength that can weaken in this bulb housing 10 top improves beam angle, light can be made more to spread, improve distribution curve flux uniformity, bulb housing 10 bottom thickness is thinner, and more light can be made to be spread by the transmission of bulb housing 10 edge.
These LED light sources 31 are located at light source board 20 top around the lateral wall of this luminous intensity distribution ring 20, and are distributed in the scope of the vertical projection of this luminous intensity distribution ring 20 on this light source board 30, and these LED light sources 31 are provided with 2 circles around this luminous intensity distribution ring 20.
In sum, by arranging transparent or semitransparent luminous intensity distribution ring 20 at light source board 30 top, multiple LED light source 31 is located at light source board 30 top around the lateral wall of this luminous intensity distribution ring 20, the part light that this lateral wall is used for these LED light sources 31 to send reflects along the direction of this body of deflection, and the light that the described LED light source 31 of part sends is by the top of this bulb housing 10 of directive after the lateral wall of this luminous intensity distribution ring 20 and madial wall refraction.The irradiation of the uniform light that LED light source so just can be made to send, in the top of bulb housing and bottom, realizes wide-angle luminescence.Because bulb housing 10 was hemisphere cell-shell and its bottom thickness is thinner, the obstruction running into printing opacity scattering material when thinner thickness means that light passes was less, and like this, the light that the light of injection just penetrates than other parts bottom this bulb housing 10 is more.This just makes the lighting angle of this LED become large, and not only top has uniform light to illuminate, and bottom also has uniform light to illuminate.So this LED has the simple and advantage of uniform-illumination of structure.
