Abstract
The utility model relates to a LED lamps and lanterns field, concretely relates to fei nieer light -passing board. Fei nieer light -passing board is formed by at least four fresnel lens rigid couplings, and fresnel lens is array distribution, and each fresnel lens all is equipped with at least one annulus, and two adjacent fresnel lens's annulus is crossing, and crossing department is equipped with the breach that supplies light to pass through. Fraction in the light that the light source sent can pass through this breach directive fresnel lens adjacent with this light source position, and the facula part that makes adjacent fresnel lens reveal is coincided to the light and shade that makes the illuminating effect is more even, and so as to reduces user's visual fatigue, and can prevent myopia.
Description
Technical field
This utility model is related to LED lamp field and in particular to a kind of Fresnel light-passing board.
Background technology
Fresnel light-passing board is provided with Fresnel Lenses.The side of Fresnel Lenses is flat surface, and opposite side is by multistage
The ladder curved surface that concentric annular portion is constituted.Fresnel Lenses thinner thickness, can reduce the light attenuation producing during light transmission lens,
Thus it is often used as LED lamp light-passing board.In the prior art, each Fresnel Lenses is separate, and that is, each Fresnel is saturating
The ladder curved surface of mirror is independent mutually so that each light source is through the illumination after its corresponding Fresnel Lenses, between each lens
Hot spot is relatively independent, and integral illumination effect has light and dark situation, is therefore easily caused user and produces asthenopia.If long
Phase is in reads under directional light, is easily caused myopia.
Content of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of Fresnel light-passing board, and it can reduce
The visual fatigue of user, and can pre- myopia prevention.
The Fresnel light-passing board that this utility model provides, is formed by least four Fresnel Lenses are affixed, Fresnel Lenses
In array distribution, each Fresnel Lenses be equipped with least one annulus it is characterised in that: two neighboring Fresnel Lenses
Annulus intersect, and intersection is provided with the breach passing through for light.
Specifically, heart position is provided with cambered surface portion to Fresnel Lenses wherein, and described annulus are around cambered surface portion.
Specifically, described annulus quantity is three.
Specifically, described array is rectangular array.
Specifically, the orientation of described two neighboring Fresnel Lenses be described rectangle wherein a line edge be located straight
The direction of line.
Specifically, the wherein a line edge of described rectangle is the shorter edge of described rectangle.
Compared with prior art, the beneficial effects of the utility model are:
The Fresnel light-passing board that this utility model provides, is formed by least four Fresnel Lenses are affixed, Fresnel Lenses
In array distribution, each Fresnel Lenses is equipped with least one annulus, and the annulus of two neighboring Fresnel Lenses intersect,
And intersection is provided with the breach passing through for light.Fraction in the light that light source sends can be by this breach directive and this light source position
Put adjacent Fresnel Lenses, so that the hot spot that adjacent Fresnel Lenses appears is partially overlapped, so that the light and shade of illuminating effect
Evenly such that it is able to reduce the visual fatigue of user, and can pre- myopia prevention.
Brief description
Fig. 1 is the partial view of Fresnel light-passing board；
Fig. 2 is the partial perspective view of Fresnel light-passing board.
Description of reference numerals:
1. Fresnel Lenses, 11. cambered surface portions,
12. annulus, 13. breach.
Specific embodiment
With the following Examples this utility model is further described.
The Fresnel light-passing board that the present embodiment provides, is shown in Fig. 1, is rectangle tabular.Fresnel light-passing board is by multiple phenanthrene alunites
Lens 1 are affixed forms for you, and each Fresnel Lenses 1 is in array distribution.See Fig. 2, Fresnel Lenses 1 is provided with arc at its center
Face 11 and three successively around the annulus 12 in cambered surface portion 11.Along the direction a of Fig. 1 and Fig. 2, two neighboring Fresnel Lenses 1
The intersection of annulus 12 be provided with breach 13.
Fraction in the light that light source sends is mapped to along the adjacent Fresnel Lenses of direction a 1 by breach 13, then passes through
This adjacent Fresnel Lenses 1 projects, and so that the hot spot that adjacent Fresnel Lenses appears is partially overlapped, so that illuminating effect
Light and shade is evenly such that it is able to reduce the visual fatigue of user, and the pre- myopia prevention of energy.
Finally it should be noted that above example is only in order to illustrating the technical solution of the utility model, rather than to this reality
With the restriction of novel protected scope, although having made to explain to this utility model with reference to preferred embodiment, this area general
Lead to it will be appreciated by the skilled person that the technical scheme of utility model can be modified or equivalent, without deviating from this reality
Spirit and scope with new technique scheme.
