Description

Spot light 180 degree angular direction astigmat

Technical field

The utility model is related to lamp lighting, more particularly to a kind of spot light 180 degree angular direction astigmat.

Background technology

Spot light, including LED (light emitting diode), laser etc., directly convert electrical energy into visible ray and spoke as one kind The luminescent device of energy is penetrated, with some row advantages, such as operating voltage is low, power consumption is small, use mission length, photoelectric transformation efficiency Height, the advantages of stable and reliable for performance.

At present, the light fixture using spot light as light source typically all uses and light source is fixed on gelled heat abstractor On, and the light sent with reflection shield to LED carries out reflection and makes light fixture, or the radiation direction sent according to spot light compares one Cause, light compare concentrations, injection smooth surface in front of characteristic, change light distribution in direction of illumination plus a lens.

However, traditional optical lens such as cylindrical mirror or spherical mirror for using mostly etc., their exiting surface typically uses one Individual smooth flat or smooth surface, light extraction is more concentrated, it is necessary to which relatively long distance diffusion could scatter light extraction.

The content of the invention

It is an object of the invention to provide a kind of spot light 180 degree angular direction astigmat, it effectively can send out spot light The light gone out is diffused into shorter distance around 180 degree angular direction, while improving Luminescence Uniformity and brightness.

Scheme of the present utility model is as follows：

A kind of spot light 180 degree angular direction astigmat, including preceding collimation plane, lens connector, reflection from lens face, lens Exit facet, described lens connector is that inside is cone, described reflection from lens face for coating film on glass or film coated plastic or Metal coating or medal polish.

The big I of cone angle in described reflection from lens face is adjusted in 180.

Described reflection from lens face position can be moved with off-center adjustment to the left and right.

Described lens exit facet is arcwall face.

Described lens connector material is high light-conductive rate glass or resin.

The beneficial effects of the utility model：

Spot light 180 degree angular direction astigmat of the present utility model, using highlighted spot light as illuminating source, very short Distance, can preferably by light to 180 degree angular direction disperse effect, with simple in construction, it is not easy to by deposition dust influenceed, It is with low cost, and optical efficiency it is high the advantages of.

Embodiment

In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with Similar technical scheme is obtained according to these technical schemes.

Embodiment one：Referring to Fig. 1, a kind of spot light 180 degree angular direction astigmat, including the connection of preceding collimation plane, lens Body and lens exit facet, described preceding collimation plane are made up of arc light refraction face and optical total-reflection face, what spot light was sent Light described lens connector of parallel entrance behind optical total-reflection face by described light refraction face, parallel rays is through cone Shape reflecting surface, changes direction, is dissipated by lens outgoing towards surrounding.

Described reflection from lens face is coating film on glass or film coated plastic or metal coating or medal polish.

Described lens exit facet is arcwall face.

Described lens connector material is high light-conductive rate glass or resin.

Only illustrate the mentality of designing of the present invention in one embodiment above, in the case where system allows, this hair It is bright to expand to external more functional modules, including be not limited to shown in Fig. 1 to 8 simultaneously, so as to extend to greatest extent Its function.
