Utility model content
For deficiency of the prior art, the technical problems to be solved in the utility model there are provided a kind of can by collimate light injection and the collimated illumination LED of the low ultra-thin sawtooth lens of band of cost.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of collimated illumination LED with ultra-thin sawtooth lens, comprises LED light emitting source main body and is installed on the lens in LED light emitting source main body, wherein:
Described LED light emitting source main body comprises aluminium base and is located at the LED light emitting source on described aluminium base;
Described lens are the taper shape clipping upper end, and its whole curved surface is provided with the Saw blade distributed along conical generatrix direction.
Further, the bottom surface of width from the end face of described lens to described lens of described Saw blade reduces gradually.
Further, described lens are provided with the cylindrical groove laying LED light emitting source, and described cylindrical groove is given prominence to from the bottom surface of described lens, and the end face of described lens concaves formation circular groove.
Further, after the light that LED light emitting source sends arrives lens, point three parts penetrate, and one is penetrate from lens through refraction after light is mapped to the end face of described cylindrical groove; Its two exterior side surface being mapped to described cylindrical groove for light penetrates from lens through reflection; Its three end face being mapped to described lens for light is mapped on Saw blade after reflection, then penetrates from lens after two faces reflections of Saw blade.
Further, from the light collimation injection that described lens penetrate.
Further, described LED light emitting source is COB area light source.
Further, the thickness of described lens is 9 millimeters.
The beneficial effects of the utility model are:
The collimated illumination LED of the ultra-thin sawtooth lens of band of the present utility model, by arranging the Saw blade distributed along conical generatrix direction on the whole curved surface of conical lens, Saw blade can cleverly light reflection and reflecting, make light collimation injection after the reflection of the two sides of Saw blade again after the reflection of lens, and arrange Saw blade compared to existing technology in plated reflective film make cost low, yield is high; In addition, the TIR lens of the Thickness Ratio routine of lens want much thin, and it is less that the volume of such lamp can do, and economizes on resources.
