Abstract
The utility model relates to a light distribution lens for illumination and a lamp thereof. The light distribution lens comprises a small end face, a large end face and a fully-reflecting surface, wherein the small end face is provided with an opening for placing a light source, and the light source is a point light source, an area light source or a volume light source; and the fully-reflecting surface is in a shape of an annular belt or a radial strip or a combination thereof. According to the lamp, the opening for placing the light source is formed on the small end face of the lens; a driving circuit of the light source and a light source radiating device are arranged above the opening. Light rays emitted by the light source are cut by microstructures on the fully-reflecting surface and the end faces of the lens, namely the individual light source is divided into a plurality of small light sources, so that the brightness of the light source is reduced under the condition that the efficiency of the light source is not reduced, and an aim of preventing dazzle and glare is fulfilled; and by cutting the light source, the adaptability of the lens to the light source is increased, and when the lens is matched with the light sources of similar specifications in different brands, the possibility of generating yellow spots and diaphragms is reduced.
Description
Technical field
The utility model relates to lighting, particularly relates to a kind of employing total reflection Lamp cup and adds high-adaptability lighting that micro-structural (like micro mirror array or Fei Nieer face) reaches anti-dazzling anti-dazzle with light-distribution lens and light fixture thereof.
Background technology
Fig. 1, be that existing room lighting is with light-distribution lens and light fixture thereof shown in 2; Described lighting is with many independently light source 202 regular being arranged on PCB (wiring board) plate 203; Lens 201 are one to one arranged above light source with it, and every lens 201 carry out redistributing of light to light source 202 corresponding with it separately.The face type of scioptics is controlled and is reached various rising angles and the light spot shape that light fixture requires.This kind lens can solve the problem of light fixture light distribution and hot spot Illumination Distribution preferably, but do not solve the emitting brightness problem of light fixture, hot spot illumination also can't accomplish evenly soft excessively, be difficult to solve dazzle and dazzling problem.Particularly this kind lens are to the having relatively high expectations of light source, and lens are difficult to that the similar light source of different brands is carried out luminous intensity distribution to be handled, and the nearmis of light source often causes phenomenons such as macula lutea and aperture.
The utility model content
The utility model aims to provide a kind of illumination and uses light-distribution lens; It is the technical solution that the bad adaptability of Different Light is proposed with the dazzling glare problem that often occurs to existing lighting technology; The light fixture that is equipped with these lens has better light source adaptability and more comfortable visual experience, effectively prevents problems such as dazzling and dazzle.
The technical scheme of the utility model is: light-distribution lens is used in a kind of illumination, comprises small end face, and large end face, fully reflecting surface, said small end face offer the opening of placing light source.
Said fully reflecting surface is endless belt shape or radial bar shaped, or above both combination.
But said fully reflecting surface plated film or plated film not.
Said fully reflecting surface is plane or curved surface.
Said large end face is plane or curved surface or micro mirror array, and the single-order or the multistage step of indent can be arranged.
The opening that said small end face is placed light source is barrel-shaped, and said barrel-shaped open bottom end is Fei Nieer face or plane or curved surface or micro mirror array.
The side line of said barrel-shaped open profile is straight line or curve.
Another purpose of the utility model provides a kind of light fixture with this patent light-distribution lens.
The technical scheme that realizes another purpose of the utility model is: a kind of light fixture with this patent light-distribution lens, place light source at the opening part of the small end face of said lens, and light source driving circuit and light source radiating device are placed in the opening top.
The utility model provide a kind of to the light source high-adaptability, effectively the illuminating light distribution lens and the light fixture thereof of anti-stab dizzy light; Lens have the fully reflecting surface of a bowl-type; Two planes of refraction comprise small end face of a large end face; Small end face is provided with the opening that can place light source, and fully reflecting surface is made up of a plurality of endless belt face or strip-shaped surface that clocklike have total reflection characteristic, and small end face bottom and large end face bottom can be plane or curved surface or Fei Nieer face or micro mirror array.
The purpose of the utility model is to realize like this; Endless belt or bar shaped through fully reflecting surface are cut in the face of the high angle scattered light that light source sends; Single endless belt or bar shaped are carried out shaping in the face of the local light that is assigned to above it; Light after the shaping is according to certain light distribution bright dipping; All endless belt or bar shaped in the face of after the light source cutting again according to preset light distribution bright dipping, stack shines the zone that needs illumination, reaches high-adaptability and the anti-glare dazzling purpose of lens to light source with this; For the low-angle light of scioptics small end face bright dipping, through Fei Nieer face or micro mirror array low-angle light is cut equally, and light is carried out shaping, reach the go out light effect the same with fully reflecting surface.
The utility model is through face type, quantity, locus and the arrangement mode of the endless belt of change fully reflecting surface; The size of the big small end face of fit lens and face type; Realize the different light distribution effects of this patent lighting, as common 15 °, 20 °, 25 °, 30 °, 35 ° 40 °, 50 °, 60 ° etc.
Adopt the lens of the utility model; Because the fully reflecting surface of lens and the endless belt on the end face or micro mirror array or Fei Nieer cut in the face of the light that light source sends; Be equivalent to be divided into many small light sources to single light source; So just realized under the situation that does not reduce source efficiency, having reduced the brightness of light source, reached anti-glare dazzling purpose; Cutting to light source has simultaneously increased the adaptability of lens to light source, when the close specification light source of lens couplings different brands, has reduced the possibility of macula lutea and aperture appearance.
