Description
Technical field
The utility model is related to lighting technical fields, and in particular to a kind of anti-glare lens and lamps and lanterns.
Background technology
In lighting technical field, it is typically to have different requirements to lamps and lanterns to be directed to different lighting environments, for example, right
In the high-end occasion such as hotel, just there is higher requirement for the dazzling effect of lamps and lanterns.For the dazzling effect of lamps and lanterns, reason
It is to be：The light of light source is directly reflected by lens, this some light pass through reflection from lens region reflect, brightness compared with
Height, the low-angle light for the central part that emits beam especially in light source, this some light are more concentrated, and energy force density is high,
After directly reflecting lens without the adjustment of reflection from lens region, dazzling effect is with regard to more serious.
Currently, above-mentioned dazzling in order to solve the problems, such as, setting blocking parts is blocked typically on lens, is come with this
Avoid some light from reflecting lens, using this kind of mode, although dazzling effect can be avoided, its still there is also
There is deficiency, it is specific as follows to state：By the way of blocking parts, on the one hand it is to be related to secondary installation step, not only increases manufacture
Cost reduces production efficiency, and when assembly precision is not high, is also easy to block the light of other parts, and then give light distribution
Effect brings adverse effect；On the other hand, the light being blocked collects in blocking parts, and then the partial heat is made to increase, no
Lamps and lanterns working life can be only reduced, but also lens thermal deformation may be caused and lead to the reduction of light distribution effect.
So it is desirable to dazzling effect can either be reduced by designing one kind, and manufacture can be facilitated, and can ensure
The fitting structure of the good service life of lamps and lanterns.
Invention content
The purpose of this utility model is that：Cause to reduce dazzling effect to be inconvenient to manufacture for current lamps and lanterns and to
Service life brings the deficiency of adverse effect, and dazzling effect can either be reduced by providing one kind, and can facilitate manufacture, and can
Ensure the fitting structure of the good service life of lamps and lanterns.
To achieve the goals above, the technical solution adopted in the utility model is：
A kind of anti-glare lens, including incident area, exit area and the first reflector space, further include the second echo area
Domain, the incident area are matched with light source, and the light that lens are refracted by the incident area is divided into two parts, refracts to
First reflector space is first part's light, remaining light is second part light, and first part's light is through the
One reflector space reflexes to the exit area, then reflects lens forming illumination spot through the exit area, and described
Two some lights are whole or chief ray therein reflexes to the incident area through second reflector space.
The anti-glare lens of the application, due to the light that there are the first reflector space and the second reflector space, light source is sent out
In line, a portion is adjusted to meet lighting requirement under the cooperation of incident area, the first reflector space and exit area
Illumination spot, and without the first reflector space reflection light all or this some light in chief ray part then by
Second reflector space is reflected into incident area, not by reflecting lens, in this way, glare effect is directly reduced, moreover, these light
Line does not also converge near the exit area of lens, can reduce because light convergence leads to the risk of light extraction region deformation, into
And ensure good light distribution effect.
Preferably, the second part light is whole or chief ray therein is reflexing to incidence by the second reflector space
Behind region, refracted near light source or light source through the incident area.
As above-mentioned, the whole chief rays either therein of second part light are refracted to light source or light source, this
In scheme, light source is nearby for around the position that is closer to light source periphery, in this manner, this some light not by
Lens absorb, in this way, the problem of reducing over-heating heating lens, moreover, in fitting structure, light source and light source are nearby
The higher position of temperature, and then the caused temperature change of some light convergence is allow to ignore, so avoid this partial heat
Adverse effect while improving lamps and lanterns service life, also further reduced lens thermal deformation risk, it is ensured that
The light distribution effect of lens.
Preferably, the second part light is the light near central optical axis.
Using above-mentioned scheme, reason is：It is low-angle light in central optical axis attachment during light source emits beam,
On the one hand it is to be not easy to lens to adjust to form illumination spot, on the other hand, this some light energy density is high, so, in this Shen
This some light please be reflected back light source, the dazzling effect of lamps and lanterns can be further reduced, also can further drop in scheme
Low lens thermal deformation risk.
Second reflector space is fully reflecting surface as a preferred method,.Second reflector space uses fully reflecting surface
Form, lens arrangement is relatively simple, facilitates the processing and manufacturing of lens.
Second reflector space is made of several reflector elements as a preferred method,.Using several reflector elements
The form of composition forms the second reflector space, can facilitate the chief ray whole to second part light or therein to adjust
It is whole, it can be whole by second part light according to actual needs or chief ray therein is reflected into the suitable position on light source.
Several annular grooves are arranged concentrically on the lens as a preferred method, the groove section is radially
Cross sectional shape be V-arrangement or U-shaped, the side walls of adjacent grooves mutually connects to form second reflector space successively.Second echo area
Domain is using the form of several V-shaped grooves or U-lag, and the two side of each groove is as reflecting surface, after the splicing of each groove, shape
Keep second part light whole or key light therein in this manner for undulatory second reflector space at section
Line is on the one hand to be conducive to control of second reflector space to light all at least through directive light source position again after two reflective surfaces
On the other hand system has been also convenient for processing and manufacturing.
Preferably, the central axis of the annular groove and the central optical axis of the lens coincide.In this way, ensuring ability
Intensive low-angle light beam enters in the second reflector space.
Preferably, the incident area is divided into the first incident area and the second incident area, first incident area with
First reflector space, which matches, controls first part's light, second incident area and second echo area
Domain matches chief ray whole to the second part light or therein and is adjusted.Using the program, by incident area
It is divided into the first incident area and the second incident area, the light for further increasing the application lens adjusts and control ability.
It is further preferred that second incident area is the convex-shaped away from the second reflector space protrusion.One side
Face is can easily to ensure that second part light is whole or chief ray therein can be reflected onto light source, another party completely
Face can also effectively avoid second part light whole or chief ray therein converged when being reflected onto light source for any or
Person collects in smaller area, the problem for causing the regional temperature excessively high, and then also ensures the service life of light source.
Disclosed herein as well is a kind of lamps and lanterns：
