The utility model passes optical assembly by described support with optically focused and is fixed into the bouquet shape, make total-reflection type optically focused head large as far as possible reception sunshine in the acceptance angle scope will say that also the large tracts of land sunshine that receives is gathered into the small size sun light beam of comparatively concentrating, then import the indoor place that need to throw light on via described optical fiber.
Above-described total-reflection type optically focused head comprises the compound many curved surfaces concentrator of total-reflection type, convergent mirror and adapter sleeve, the compound many curved surfaces concentrator of total-reflection type comprises tapered of top and lower cylindrical face, the compound many curved surfaces concentrator of total-reflection type is connected adapter sleeve with optical fiber and connects, and convergent mirror is between the compound many curved surfaces concentrator of total-reflection type and optical fiber.Select suitable parameter, will so that the sunshine of just injecting only on tapered of top and lower cylindrical face respectively reflection once just assemble on the focus of the compound many curved surfaces concentrator of total-reflection type, forms preliminary orientation convergence.
The compound many curved surfaces concentrator of above-described total-reflection type and convergent mirror are made by a monolithic glass, and adding man-hour can whole cast.
Above-described convergent mirror comprises single spherical lens and the Fresnel mirror of glass material, it is arranged between the compound many curved surfaces concentrator of total-reflection type and the optical fiber is for to assembling from the reverberation of the compound many curved surfaces concentrator of total-reflection type again, make it the angle of divergence and reduce, on the optical fiber that connects after being beneficial to more effectively be coupled to.
Above-described adapter sleeve upper taper inwall is equipped with one or two inboard and is the ring washer of tapered wall, lower cylindrical shape inwall is equipped with the ring washer that one or more inboards are straight wall, make between the compound many curved surfaces concentrator of total-reflection type and the adapter sleeve layer of air is arranged, the reflecting interface both sides that make the compound many curved surfaces concentrator of total-reflection type are glass and air, guarantee the reflection of light effect.
Total-reflection type optically focused head has an acceptance angle, and different total-reflection type optically focused heads is different direction skywards.Total-reflection type optically focused head has adopted total reflection principle, the compound many curved surfaces concentrator of total-reflection type wherein can be realized directional focusing to the sunshine of normal incidence, for the optical fiber that allows its bottom connect more effectively receives and transmits luminous energy, adopt convergent mirror that angle of flare is zoomed in, by optical fiber that the sunshine importing that receives is indoor again, can realize room lighting.If incident light and optical axis are not parallel, as long as in designed acceptance angle scope, device still can transmit sunshine effectively.
The beneficial effects of the utility model are:
1, adopt the compound many curved surfaces concentrator of total-reflection type, have the directional focusing effect, spotlight effect is good, and is practical.
2, adopt optical fiber transmission light, sunshine can be introduced room lighting, the lamp terminal position can be according to needing at any time change in certain scope.
3, adopt receiving plane that a plurality of optically focused pass optical assemblies facing to the different direction in space, do not need the tracking means can be to effective collection of sunshine.
4, whole lighting system structure is simple, and is with low cost, do not have moving component, working stability, and the life-span is long, and is non-maintaining.
