Description
Technical field
The utility model relates to optical equipment, especially the LED lens.
Background technology
The general diameter of LED lens is 3～10mm, sheet type, and volume is less, and it helps to promote the light extraction efficiency of LED, the optical field distribution of change LED, is commonly used on the led chip.Existing application is mainly two kinds of penetration and refraction-reflections in the lens of LED.
In penetration; Refraction can take place and optically focused in light when LED light passes through curved surface of lens; And when between adjustment lens and the LED apart from the time angle also can change; But because the restriction of lens diameter and lens pattern, there is apparent in view yellow limit at the not high and hot spot edge of the light utilization efficiency of LED; Refraction-reflection can obtain light utilization and beautiful hot spot effect preferably; But how to adjust the structure of reasonable LED lens; Rationally utilize luminous flux; Realization evenly, the one side of light distribution efficiently need be with varying depending on the application, and how each several part realizes that the adjustment of astigmatism or optically focused also can be owing to the different needs of using need to make up and adjust on the other hand.
Summary of the invention
The utility model technical problem to be solved provides a kind of LED lens, solves that existing penetration LED lens light utilization rate is not high to have apparent in view yellow limit with the hot spot edge, and refraction-reflection LED lens adjustment difficulty relatively, uses inconvenient defective.
The technical scheme of the utility model adopts lens; The profile that it is characterized in that lens becomes truncated cone-shaped basically; Big nose circle in truncated cone-shaped is one section cylinder, on cylindrical front end face, is shaped on the parallel protruding rib that is uniformly distributed with, and the cross section of protruding rib is circular arc; In the middle of the roundlet end of truncated cone-shaped, a square opening, the top of square opening being arranged is convex spherical.
The radius of the cylinder: protrusion rib height: the projection of the top edge spacing: the side length of the square holes: Square hole Hole depth: square holes in the top of the convex spherical surface height: the front end surface of the cylinder to circular? Cone small round end of the distance ratio were used 100:1:10:30:40:25:100 or 100:3:20:40:60:35:90 or 100:2:20:30:40:30:100 or 100:2:15:30:50:35:100 or 100:3:20:30:40:20:100 or 100:4:10:40:50:30:100 or 100:4:20:30 : 40:30:100.
The beneficial effect of the utility model: during use; Can the LED lamp be put into the perforate of round platform bottom; Light passes through to the cylinder front surface through the refraction diffusion of the sphere of the convexity of said perforate from the rear portion, and the protruding rib structure through front surface makes light proceed to disperse; Thereby make brightness and the uniformity of this light all than higher; Because the regulating action of the proportionate relationship of the distance parameter of the height of the hole depth of the top spacing of said cylindrical radius, the height of protruding rib, protruding rib, the length of side of square opening, square opening, the top convex spherical of square opening, the little nose circle of cylindrical front end face to truncated cone-shaped makes that the brightness of this light and the uniformity are higher, especially when said cylindrical radius: the height of protruding rib: the top spacing of protruding rib: the length of side of square opening: the hole depth of square opening: the height of the top convex spherical of square opening: the ratio of the distance of the little nose circle of cylindrical front end face to truncated cone-shaped adopted respectively 100: 1: 10: 30: 40: 25: in the time of 100; The brightness of this light and the uniformity are extremely high; And no longer need carry out the adjustment of distance and angle between light source and the lens, so, use also very convenient; Be specially adapted to back light; Utilize the utility model to process LED lamp bar, utilize this LED lamp bar to process advertising lamp box, the image quality of advertising lamp box is very high.
