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.
The wide-angle bulb lamp 100 of first embodiment of the invention, please refer to Fig. 1 to Fig. 5.
Please refer to Fig. 1, Fig. 2 and Fig. 3, this wide-angle bulb lamp 100 mainly comprises bulb housing 10, reflector 20, collector lens 30, sided lens 40, light source board 50 and body 60.This light source board 50 is arranged on this body 60 top.This collector lens 30, sided lens 40 are all arranged on above this light source board 50.This reflector 20 is arranged on above this collector lens 30.
Please refer to Fig. 2 and Fig. 3, this light source board 50 is slab construction, and this light source board 50 is provided with multiple LED light source 51, and this LED light source 51 is rounded to be arranged on this light source board 50.
Please refer to Fig. 2 and Fig. 3, this collector lens 30 is Fresnel Lenses, and this collector lens 30 reflects towards this reflector 20 for the light sent by described LED light source 51, makes this reflector 20 of most of light directive.The edge part 31 of this collector lens 30 bends to described LED light source 51, and this collector lens 30 lower surface is serrated face, and this collector lens 30 upper surface is light face.
Please refer to Fig. 2 and Fig. 3, this reflector 20 is made up of transparent or semitransparent material, this reflector 20 reflecting part light, and some light is through the top of this this bulb housing 10 of reflector 20 directive.The middle part of this reflector 20 protrudes out towards this light source board 50, and this reflector 20 can be the thin-slab structure of uniform wall thickness.This reflector 20 is for by the bottom reflection of some light towards this bulb housing 10.
Please refer to Fig. 2 and Fig. 3, this sided lens 40 is arranged between this collector lens 30 and this reflector 20.This sided lens 40 is cylindrical shell structure, preferred cylindrical shell body structure.This sided lens 40 is arranged on the periphery of described LED light source 51.This sided lens 40 is provided with refraction structure 42.This sided lens 40 is provided with printing opacity scattering material.
This refraction structure 42 be from top to bottom continuous arrangement at the serrated face of this sided lens 40 lateral surface.The end face 41 of described serrated face is roughly parallel with this light source board 50.The side 43 of this serrated face crossing with this end face 41 and relatively this end face 41 tilt.The some light that described LED light source sends by this refraction structure 42 is respectively towards top and the bottom refraction of this bulb housing.
Please refer to Fig. 2 and Fig. 3, this bulb housing 10 was semi-round ball balloon-shaped structure.
Because collector lens 30 is Fresnel Lenses, while meeting optically focused, have compared with the collector lenses such as common convex lens that cost is low, the advantage of uniform luminance; Because collector lens 30 bottom is provided with the snap fit 32 of extension, what it is such that collector lens 30 can be firm is fixed on above this light source board 50, ensure that the optical effect that collector lens 30 is stable; This sided lens 40, collector lens 30 are one-body molded with reflector 20, the structure of wide-angle bulb lamp 100 is simplified more, optimizes packaging technology; Because the edge part 31 of this collector lens 30 bends towards described LED light source 51, make this collector lens 30 be positioned at the middle part of the edge part 31 directly over described LED light source 51 relative to this collector lens 30 closer to described LED light source 51, therefore spotlight effect is better.
Please refer to Fig. 5, when this wide-angle bulb lamp 100 works, the light that this LED light source 51 sends, under the effect of this collector lens 30, makes most light be aggregated on this reflector 20 of directive.Because this reflector 20 is made up of transparent material or trnaslucent materials, therefore there is certain transmission capacity, make the light part gathered on this reflector 20 pass the top of this this bulb housing of reflector 20 directive, meet the lighting demand at top; Meanwhile, this reflector 20, by the bottom reflection of some light towards this bulb housing 10, obtains the large angle illumination scope of 300 degree.Owing to set up sided lens 40 in the periphery of this LED light source 51, and the lateral surface of this sided lens 40 is provided with refraction structure, make to be reflected towards the top of this bulb housing 10 and bottom respectively by the light of this sided lens 40, the top of illumination lamp cell-shell 10 and bottom, thus the lighting angle expanding whole lamp.This sided lens 40 is provided with printing opacity scattering material, can increase brightness uniformity.
In sum, this wide-angle bulb lamp 100 realizes large angle illumination scope by adopting collector lens 30 that light is condensed to this reflector 20 back reflection, has the simple advantage of structure.Meanwhile, because this reflector 20 is the structure that middle part protrudes out towards this light source board 50, make this reflector 20 can reach thinner requirement, therefore, it is possible to transmissive portion light meets the brightness at this bulb housing 10 top.Lower surface due to collector lens 30 is serrated face, is provided with the sided lens 40 that outer surface is serrated face simultaneously, makes the light of all angles to carry out mixed processing, realizes brightness uniformity, obtain better visual effect.
Understandable, the serrated face of this collector lens 30 lower surface can adjust the quantity of sawtooth and shape according to the optical effect that specifically will obtain, and can not be the broached-tooth design in embodiment.Same, the sawtooth quantity of the lateral surface of this sided lens 40 and shape also can adjust according to concrete optical effect, can not be the broached-tooth designs in embodiment.
Please refer to Fig. 4, the structure of this reflector 20 can also be other structures: such as, and the middle part of reflector 20 protrudes out towards this light source board 50, and this reflector 20 upper surface 21 is provided with the V-type groove at several intervals, and this reflector 20 lower surface 22 is light face.The V-type groove arranging several intervals can make reflection ray more even, and the thickness of reflector 20 can be made thinner, be preferred case study on implementation simultaneously.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
