Utility model content
For the weak point existed in above-mentioned technology, the high-boron-silicon glass lens covering brilliant COB light source for street lamp that the utility model provides a kind of high transmission rate, condenser performance and weather resistance all good, the problem that these lens had both eliminated the continuation choice for use secondary light-distribution lens that will face when terminal uses turn avoid the suitable waterproof gasket cement of cooperation selection to carry out the loaded down with trivial details of waterproof sealing process.
For achieving the above object, the utility model provides a kind of high-boron-silicon glass lens covering brilliant COB light source for street lamp, comprise the lens body be made up of high-boron-silicon glass material, described lens body comprises the lens section prolonging edge and the oval hemispherical shelled peanut shape upwards in bulge-structure upwards turned down; The surface of described lens section is provided with in the width direction the parabolical texture that many have optically focused effect, the width of this many texture by lens section centre to both sides in the structure distribution of successively decreasing gradually, and often form insert structure between adjacent two textures; The inside centre of described lens section is provided with in the width direction can protection packaging chip and the groove of tool optically focused effect.
Wherein, the peripheral edge place, bottom of described lens section is provided with the pressure ring matched with the shape size of external fixator.
Wherein, described pressure ring is engaged successively by multiple arc shape outer lug head and the tail varied in size and forms.
Wherein, the holddown groove had for fixing these lens that to cave between edge and lens section is prolonged described in.
Wherein, the cross section indentation structure distribution of described many textures.
Wherein, the curved structure distribution of inwall of described groove, and this groove is half cylindrical structure.
The beneficial effects of the utility model are: compared with prior art, the high-boron-silicon glass lens covering brilliant COB light source for street lamp that the utility model provides, lens made by direct employing high-boron-silicon glass material, make these lens have excellent condenser performance and weather resistance, lens coordinate oval hemispherical shelled peanut shape structural design and have the design of parabolical texture of optically focused effect, the lens of this design are directly designed on light source product, both the problem having eliminated the continuation choice for use secondary light-distribution lens that will face when terminal uses turn avoid to coordinate selects suitable waterproof gasket cement to carry out the loaded down with trivial details of waterproof sealing process, the light of light source carries out cooperation process by these high-boron-silicon glass lens after being reflected in the course of the work, luminous energy can farthest be utilized, greatly improve the luminous efficiency of light source, but also the gold-tinted circle problem produced when eliminating luminescence, further, the design of groove, can make glue face not contaminated by the chip after protection packaging, can also prevent the infiltration of moisture and air, completely cut off glue face and contacted with the direct of environment, greatly delayed the aging of glue face, the service life of light source is greatly improved.

Detailed description of the invention
In order to more clearly state the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1-3, the high-boron-silicon glass lens covering brilliant COB light source for street lamp that the utility model provides, comprise the lens body 1 be made up of high-boron-silicon glass material, lens body 1 comprises the lens section 11 prolonging edge 10 and the oval hemispherical shelled peanut shape upwards in bulge-structure upwards turned down; The surface of lens section 11 is provided with in the width direction the parabolical texture 111 that many have optically focused effect, the width of this many texture 111 by lens section 11 centre to both sides in the structure distribution of successively decreasing gradually, and often form insert structure between adjacent two textures 111; The inside centre of lens section 11 is provided with along the direction of width can protection packaging chip and the groove 112 of optically focused.Prolong the holddown groove 13 had for fixing these lens that to cave between edge 10 and lens section 11.
Compared to the situation of prior art, the high-boron-silicon glass lens covering brilliant COB light source for street lamp that the utility model provides, directly adopt high-boron-silicon glass material to make lens, make these lens have excellent condenser performance and weather resistance, lens coordinate oval hemispherical shelled peanut shape structural design and have the design of parabolical texture of optically focused effect, the lens of this design are directly designed on light source product, both the problem having eliminated the continuation choice for use secondary light-distribution lens that will face when terminal uses turn avoid to coordinate selects suitable waterproof gasket cement to carry out the loaded down with trivial details of waterproof sealing process, the light of light source carries out cooperation process by these high-boron-silicon glass lens after being reflected in the course of the work, luminous energy can farthest be utilized, greatly improve the luminous efficiency of light source, but also the gold-tinted circle problem produced when eliminating luminescence, further, the design of groove, can make glue face not contaminated by the chip after protection packaging, can also prevent the infiltration of moisture and air, completely cut off glue face and contacted with the direct of environment, greatly delayed the aging of glue face, the service life of light source is greatly improved.
In the present embodiment, the peripheral edge place, bottom of lens section 11 is provided with the pressure ring 12 matched with the shape size of external fixator.After after chip and lens packages, need a whole set of light source to be enclosed within external fixator, these lens adopt pressure ring 12 to realize fixing of lens and external fixator.Pressure ring 12 is engaged successively by multiple arc shape outer lug 121 head and the tail varied in size and forms.Certainly; be not limited to the concrete structure of pressure ring 12 in this case, can change according to the structure of practical matter and external fixator, if the embodiment changed pressure ring 12 concrete structure; all belong to the simple deformation to this case or conversion, fall in the protection domain of this case.
In the present embodiment, the cross section indentation structure distribution of many textures 111.Certainly, it is the distribution of laciniation that the cross section of texture 111 is not limited to, and can also be other shapes; The curved structure distribution of inwall of groove 112, and this groove 112 is in half cylindrical structure.Arc and the height of this groove 112 can design according to the needs of street lamp optics.In addition, in this case, the length of lens can carry out increasing or reducing in conjunction with the needs of the light emission rate of chip with height.
Be only several specific embodiment of the present utility model above, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
