Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
Please refer to Fig. 1 to Fig. 3, this all-round smooth LED 100, comprise lens 10, LED light source plate 20 and body 30, the bottom cover of these lens 10 is located at the top of this body 30, this LED light source plate 20 comprises substrate 21 and is arranged on the multiple LED light sources 22 on this substrate 21, this LED light source plate 20 is arranged on this body 30 top, and the corresponding described LED light source 22 in bottom of these lens 10 is provided with caustic surface 121, and the end face of these lens 10 is provided with reflective surface 11.
Please refer to Fig. 1 to Fig. 4, these lens 10 are column structure, the size being dimensioned slightly smaller than or being greater than this body 30 of this lens 10 sidewall.Preferably, the size of this lens 10 sidewall is more than 0.8 with the scope of the ratio of the size of this body 30, like this, can prevent this body 30 from blocking the light sent from these lens 10 sidewall.The bottom cover of these lens 10 is located at the top of this body 30.This lens 10 bottom margin is provided with pin 13, and this pin 13 is connected and fixed by buckle with this body 30.The end face of these lens 10 is provided with reflective surface 11, and preferably, this reflective surface 11 is the taper seat (as shown in Figure 3) that middle part protrudes out towards described LED light source plate 20.These lens 10 are made up of transparent or semitransparent material, and some light can penetrate from the top of these lens 10 through reflective surface 11.The bottom of these lens 10 is provided with accepting groove 12, and this caustic surface 121 is arranged in this accepting groove 12, and this caustic surface 121 is Fresnel Lenses surface.This caustic surface 121 reflects towards this reflective surface 11 for the light sent by described LED light source 22, this reflective surface 11 for by most of light towards this lens 10 sidewall reflects, light is through the outside of direct this all-round smooth LED 100 of directive after these lens 10.Be provided with changeover portion 122 between this caustic surface 121 and this accepting groove inwall 123, this changeover portion 122 is for reflecting the sidewall of light towards these lens 10.The inwall of this changeover portion 122 is the annular wall configuration of this light source board 20 inclination relatively, by the setting at angle of inclination, light that these LED light sources 22 send, this changeover portion 122 inwall of directive major part is reflected towards the sidewall of these lens 10.
During work, the light overwhelming majority that these LED light sources 22 send is irradiated on the caustic surface 121 of these lens 10, and these are radiated on the reflective surface 11 of light these lens 10 of multiple aggregation directive after refraction of this caustic surface 121.Because these lens 10 are made up of transparent or trnaslucent materials, therefore there is certain transmission capacity, make the light part gathering this reflective surface 11 penetrate lens 10 through this reflective surface 11, make this all-round smooth LED 100 top have light to penetrate; Meanwhile, because this reflective surface 11 has reflective function, make another part light gathering this reflecting surface 11 towards the reflection of this lens 10 sidewall bottom, beam angle so just can be made to reach 320 degree.Owing to being provided with changeover portion 122 between this caustic surface 121 and this accepting groove inwall 123, like this, can arrive this lens 10 sidewall through refraction after the light sent from LED light source 22 is irradiated to this changeover portion 122, this part light is by the top-direction outgoing to these lens 10.
In sum, this all-round smooth LED 100 to this reflective surface 11 back reflection to this lens 10 sidewall bottom, makes this all-round smooth LED 100 be provided with the large advantage of lighting angle by the light-ray condensing that arranges caustic surface 121 at lens 10 and sent by described LED light source 22.And, because these lens 10 can realize wide-angle luminous intensity distribution, at needs, bulb housing is not set in addition, makes this LED 100 have the simple advantage of structure.Due to the setting of these lens 10, making this all-round smooth LED 100 without the need to arranging multiple side substrate for installing LED light source, avoiding the light sent dazzling, make this all-round smooth LED 100 be provided with good visual effect, the simple advantage of structure.Due to these lens be transparent or trnaslucent materials is made, and like this, this all-round smooth LED top has light injection, makes this all-round smooth LED 100 top not have blackening and occur.Owing to being provided with changeover portion 122 between this caustic surface 121 and this accepting groove inwall 123, make the light being irradiated to this changeover portion 122 can arrive this lens 10 sidewall through refraction, avoid this some light blocked by body and cannot penetrate, improve light extraction efficiency.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all make within spirit of the present utility model and principle any amendment, equivalent replacements, improvement etc., all should be included in scope that the utility model protects.
