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.
Fig. 1 is the three-dimensional exploded view of first embodiment of the invention LED bulb 100, and this LED bulb 100 comprises body 10, three light source boards 20, bulb housing 30 and reflectors 40.These light source boards 20 and this reflector 40 are arranged on the end face of this body 10, are fixed on the top of this body 10 bottom this bulb housing 30, and these light source boards 20 and this reflector 40 are accommodated in the inside.
Please refer to Fig. 1, these LED light source plates 20 are ceramic substrate, and each light source board 20 includes a substrate 22 and multiple LED light source 24.The front 222 of this substrate 22 is provided with reflecting layer (not shown), the part light that this reflecting layer sends for reflecting these LED light sources 24.LED light source 24 on each light source board 20 arranges along the parallel direction with this body 10 top.Each light source board 20 is thermally coupled with the top of this body 10 respectively.These light source boards 20 are rectangle thin-slab structure and the end to end top being arranged on this body 10 respectively, form a closed ring.The front 222 of these light source boards 20 is positioned opposite to each other, and the front 222 of these light source boards 20 is arranged towards the bottom of this bulb housing 30 respectively.This LED light source 24 is the area source that a phosphor powder layer (not shown) encapsulation plurality of LEDs light source is formed.Due to these light source board 20 circular array, so the LED light source 24 on front 222 is by all bottoms of this bulb housing 30 of uniform illumination.
Please refer to Fig. 1, this bulb housing 30 was hemisphere cell-shell, and the bottom cover of this bulb housing 30 is located at the top of this body 10.This bulb housing 30 is provided with light transmission scattering material.This light transmission scattering material is used for the light that these LED light sources 24 send to diffuse to space outerpace.The height of these light source boards 24 on this body 10 lower than the height bottom this bulb housing 30 so that luminous energy shines the bottom section of this bulb housing 30.Because the front of these light source boards 20 is arranged towards the bottom of this bulb housing 30 respectively, the LED light source 24 on it sends light by the bottom of direct irradiation at this bulb housing 30, thus makes the bottom of this bulb housing 30 brighter.Because the size bottom this this bulb housing 30 is greater than this body 10, therefore the light transmission scattering material on it will be launched along the direction towards this body 10 through the light bottom this bulb housing 30.
Please refer to Fig. 1, the end face of this body 10 is coated with reflector layer to form this reflector 40.This reflector 40 is thin-slab structure.Preferably, this reflector 40 is made up of heat radiation material, such as pottery etc.This reflector 40 is arranged on the end face central authorities of this body 10.These light source boards 20 are arranged on the periphery of this reflector 40 around this reflector 40 circular array.Preferably, these light source boards 20 are angularly arranged at interval around this reflector 40.This reflector 40 reflects for the light that sent by the LED light source 24 in these light source board 20 fronts top-direction towards this bulb housing 30.
During work, because these light source boards 20 join end to end the closed ring of formation one, and the front of these light source boards 20 is provided with reflecting layer, so, the light part that these LED light sources 24 send shines directly into the bottom of this bulb housing 30, another part passes through the reflection in this reflector 40 and reflecting layer, and the top-direction towards this bulb housing 30 is launched.Like this, the top of this bulb housing 30 and bottom are all bright by illumination, thus make this LED bulb 100 can realize wide-angle luminescence, and lighting angle can reach 240 ° to 300 °.
In sum, this LED bulb 100 arranges the light source board 20 of multiple annular array at the top of its body 10, make the front 222 of each light source board 20 respectively towards this bulb housing 30 bottom arrange and the front 222 of light source board 20 is positioned opposite to each other, like this, the light that the LED light source 24 in these light source board 20 fronts 222 sends just can shine directly into the bottom of this bulb housing 30, and there is the lighting angle of more than 120 ° due to LED light source 24, the top of this bulb housing 30 also can be illuminated simultaneously.This luminous energy just making these LED light sources 24 send more uniformly is irradiated on this bulb housing 30, thus avoids the dark space in prior art, bulb housing 30 occurred, makes this LED bulb 100 have the advantage of uniformly light-emitting.In addition, by arranging this reflector 40, the luminous energy that the LED light source 24 of these light source boards 20 can be made to send is reflected to the top of this bulb housing 30 more, make this LED bulb 100 Light distribation evenly.In addition, because the front 222 of these light source boards 20 is provided with reflecting layer (not shown), the part light that these LED light sources 24 send diffuses to space outerpace by this reflective layer reflects to this bulb housing 30, thus decreases light loss, enhances the luminous flux of whole lamp.In addition, because the LED light source plate 20 of this LED bulb 100 is ceramic substrate, each light source board 20 is thermally coupled with the top of this body 10 respectively, LED light source 24 on each light source board 20 arranges along the parallel direction with this body 10 top, thus the heat that these LED light sources 24 can be produced in luminescence process is dispersed in air by this light source board 20 and this body 10, shorten heat-transfer path, promote heat transfer efficiency.
Understandable, the number of this light source board 20 can be multiple.This light source board 20 can also be arranged to circulus, and such light source board only needs to arrange one piece.The light source board of circulus can make this bulb housing periphery Light distribation evenly, and not easily produce dark space.
These are only preferred embodiment of the present invention above, not in order to limit the present invention, within the spirit and principles in the present invention all, and any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
