Abstract
The utility model discloses a be adapted to low -angle lens of COB light source, it is round platform shape basically, and the up end diameter is greater than the diameter of bottom face, and the lateral wall sets up to the complete reflective surface, up sunkenly in the middle of the bottom face is formed with a holding chamber that is used for adaptation holding COB light source, just up cave in in the middle of the top and be formed with one yuan of tapered groove in the holding chamber, the up end down caves in from the centre and is formed with a obconic recess, the cell wall of obconic recess sets up to the complete reflective surface, the center pin of holding chamber, circle tapered groove and total reflection recess and the center pin of round platform shape low -angle lens are at a straight line to light diameter behind the income plain noodles at circle tapered groove top in the middle of positive is followed radius tapered groove parallel and is jetted out, and other penetrate the light on the radius tapered groove complete reflective surface then on can being reflected the lateral wall complete reflective surface of low -angle lens, then the parallel jets out behind secondary reflection.
Description
Technical field
The utility model relates to lens, particularly relates to a kind of low-angle lens being adapted to COB light source.
Background technology
In prior art, lens are generally arrange an incidence surface, light reflects away through the fully reflecting surface of lens sidewall after incidence surface again, because the light-emitting area of COB light source is larger, so the reflection of some light not through fully reflecting surface after incidence surface has just directly been shot out, thus do not reach the object of low-angle irradiation, and the utilization rate of lens is very low, and there is a lot of veiling glare at hot spot edge.
Utility model content
The purpose of this utility model is to provide a kind of low-angle lens being adapted to COB light source, and it can reach the object that low-angle irradiates, and lens utilization rate is high, and hot spot is without veiling glare.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of low-angle lens being adapted to COB light source, described low-angle lens are truncated cone-shaped substantially, the upper surface diameter of described truncated cone-shaped low-angle lens is greater than the diameter of bottom face, sidewall is set to fully reflecting surface, described low-angle lens are up recessed to form one in the middle of the bottom face for the accommodating cavity of the accommodating COB light source of adaptation, and described accommodating cavity has up been recessed to form a cone-shaped groove from crown center, the side of described accommodating cavity, the side of end face and cone-shaped groove is incidence surface, described upper surface has down been recessed to form a turbination groove from centre, the cell wall of described turbination groove is set to fully reflecting surface, described accommodating cavity, the central shaft of cone-shaped groove and total reflection groove and the central shaft of truncated cone-shaped low-angle lens are point-blank.
Described accommodating cavity is set to up-narrow and down-wide truncated cone-shaped.
The beneficial effects of the utility model are: the light of middle is directly shot out from turbination indention parallel, and other light parts are directly shot out through the fully reflecting surface reflected parallel of lens sidewall, another part is reflected to the fully reflecting surface of lens sidewall after being then mapped to the fully reflecting surface of turbination groove, parallelly again after secondary reflection to be shot out, thus lens are fully used, and all light of COB light source are all parallel after lensing is shot out, thus form the illumination of low-angle lighting angle, and hot spot edge is without veiling glare, in addition, be shot out because the light of middle is also parallel, thus also can not be dark in the middle of hot spot.
Accompanying drawing explanation
Fig. 1 is the generalized section of the utility model lens;
Fig. 2 is the utility model lens emergent ray schematic diagram.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1, shown in 2, the low-angle lens that the utility model is adapted to COB light source are truncated cone-shaped substantially, upper surface 1 diameter of described truncated cone-shaped low-angle lens is greater than the diameter of bottom face 2, sidewall is set to fully reflecting surface 3, described low-angle lens are up recessed to form one in the middle of the bottom face 2 for the accommodating cavity 4 of the accommodating COB light source of adaptation, and described accommodating cavity 4 has up been recessed to form a cone-shaped groove 5 from crown center, the side 41 of described accommodating cavity 4, the side 51 of end face 42 and cone-shaped groove 5 is incidence surface, described upper surface 1 has down been recessed to form a turbination groove 6 from centre, the cell wall of described turbination groove 6 is set to fully reflecting surface 61, described accommodating cavity 4, the central shaft of cone-shaped groove 5 and turbination groove 6 and the central shaft 7 of truncated cone-shaped low-angle lens are point-blank, thus the bottom of turbination groove 6 and cone-shaped groove 5 distance from top very near.
When light is after incidence surface, a part can directly be mapped on the sidewall fully reflecting surface 3 of low-angle lens, after the reflection of this fully reflecting surface 3, can become parallel rays and be shot out, a part then can be mapped on the cell wall fully reflecting surface 61 of turbination groove 6 in addition, in this some light, because the bottom of turbination groove 6 and cone-shaped groove 5 distance from top very near, and from light source also relatively close to, thus the light being positioned at middle can directly be shot out from turbination groove 6 is parallel after the incidence surface of cone-shaped groove 5 top section, other non-light being positioned at middle then can be mapped on other positions of turbination groove 6 fully reflecting surface 61, then after the reflection of this fully reflecting surface 61, again be mapped on the sidewall fully reflecting surface 3 of low-angle lens, then parallelly after the secondary reflection of the sidewall fully reflecting surface 3 of low-angle lens to be shot out.So, lens are fully used, namely lens utilization rate is high, and all light of COB light source are all parallel after lensing is shot out, thus form the illumination of low-angle lighting angle, and hot spot edge is without veiling glare, in addition, be shot out because the light of middle is also parallel, thus also can not be dark in the middle of hot spot.
In the present embodiment, described accommodating cavity 4 is set to up-narrow and down-wide truncated cone-shaped, and in other embodiments, the shape of described storage tank is not limit.
When the utility model low-angle lens use, the distance of itself and COB light source is fixing.
