Abstract
The utility model disclose a backlight source lens, comprising a top surface, a bottom surface and a fixed surrounding edge, wherein the fixed surrounding edge is arranged at the joint of the arc top surface and bottom surface in a surrounding manner; a light source mounting hole sinks on the bottom surface while a plurality of fixed columns are arranged on the fixed surrounding edge; a ray refraction unit is arranged at the periphery of the light source mounting hole on the bottom surface; the ray refraction unit comprises a plurality of grooves arranged in an array; the concave surfaces of the plurality of grooves refract and reflect a light source. By adopting the backlight source lens, the light source is arranged inside the light source mounting hole; a part of ray is reflected and refracted to the arc top surface to emit through the reflecting surfaces of the grooves, so that the ray emits on the arc surface in an omnibearing manner. Therefore, the demands of large irritation angle, high light flux utilization rate and high uniformity of illuminance are achieved; the luminous efficiency of a light-emitting diode (LED) lamp is improved.
Description
[technical field]
The utility model relates to lighting fitting field, relates in particular to the backlight lens in LED illumination.
[background technology]
LED illumination is a kind of emerging lighting energy because its long service life, efficiency high, consume energy low and be widely used.In backlight, also often adopt at present LED chip luminous lighting, backlight comprises luminous LED chip and lens backlight, these lens backlight and LED chip encapsulation combination, can play soft LED illumination effect, improve LED refract light rate, the luminous direction of illumination of guiding LED etc. effect.
The common backlight lens of tradition are dome dome shaped cover shape, comprise end face, bottom surface and fixing surrounding edge, the end face of arc and junction, bottom surface are around fixedly surrounding edge is set, the light source mounting hole that traps out concaves on bottom surface, and fixedly surrounding edge is provided with some a plurality of fixed legs, in order to other structure location in lens and light supply apparatus are coordinated and to be installed.
LED lamp pearl is arranged in light source mounting hole, sees through lens and emits beam from end face, and the design of existing lensed bottom surface is refracted ray well, and diffusion occurs in the Guang，Cong bottom surface that LED lamp pearl sends, loss partial luminous flux.And unreasonable due to light diffusion refraction, can not irradiate in expection launching position gathering.Can bring the problem that light efficiency is not high, illumination is lost.
[summary of the invention]
The utility model has proposed a kind of backlight lens that light source is emitted beam and reflects more fully, avoids luminous flux loss, improves light efficiency for above problem.
The backlight lens that relate to described in the utility model comprise end face, bottom surface and fixing surrounding edge, the end face of arc and junction, bottom surface are around fixedly surrounding edge is set, the light source mounting hole that traps out concaves on bottom surface, and fixedly surrounding edge is provided with a plurality of fixed legs, on bottom surface, light source mounting hole periphery has light refraction unit, this light refraction unit comprises the recessed groove of a plurality of arranged in arrays, and the concave face of the plurality of recessed groove reflects reflective to light source.
This bottom surface is circular, and the circle that light refraction unit is circular ，Gai overlay area in overlay area, bottom surface becomes arranged in concentric circles with light source mounting hole.
This recessed groove side of being taper, has four leg-of-mutton reflectings surface.
This end face is irregular arc top surface, and end face caves inward.
At this, fixedly on surrounding edge, be provided with three locating dowels.
The utility model is arranged on light source in light source mounting hole, the reflecting surface reflection of part light by recessed groove and refract to arc top surface and carry out outgoing, make light carry out comprehensive outgoing in cambered surface, reach the requirement that lighting angle is large, utilance is high, uniformity of illuminance is high, improved the luminous efficiency of LED lamp.
