Abstract
An adjustable type sunlight illuminating system comprises a spotlight unit, an internal wall total reflection straight cylinder, total reflection straight cylinders, a corner reflection unit and an illuminating unit; the plurality of total reflection straight cylinders and the corner reflection unit are connected to form into a sunlight transmission channel from exterior to interior; the spot light unit is connected to an outdoor end of the sunlight transmission channel; the sunlight transmission channel also comprises a light regulating unit; the light regulating unit comprises two spoke wheel type supports which can rotate relatively; the two spoke wheel type supports are in concentric shaft coupling; one spoke wheel type support is fixedly connected with the internal wall of the sunlight transmission channel. The adjustable type sunlight illuminating system has the advantages of replacing the traditional silica fibers which are expensive in cost, achieving the sunlight direct guiding function, guaranteeing the system transmission power and the low costs and meanwhile enabling indoor complex illuminating light path arrangement to be convenient due to the plastic optical fibers after beam split at the indoor end, enabling illuminating point arrangement to be flexible and achieving the purpose of adjusting light intensity due to the fact that the wheel type supports of the light regulating unit drive shade cloth to shield the sunlight transmission channel when rotate relatively.

Solar energy is a kind of inexhaustible renewable and clean energy resource, along with the research 20th century solar energy development being utilized is goed deep into, such as can generate electricity very much, the various technology of solar energy of utilizing such as solar thermal utilization (water heater) continue to bring out, wherein sun light lighting is exactly an important directions of Application of Solar Energy, concrete scheme is under the sun, to collect sunshine by a device, then sunshine is imported to indoor illumination by guiding device (as optical fiber, light conducting cylinder etc.).With after solar electrical energy generation, by electric energy, drive illumination to compare to have saved transfer process complicated in the middle of photocell again, equipment is simpler, is easier to promote.But the sunshine leading-in technique that sun light lighting adopts at present but exists the shortcoming that cost is high, the silica fibre cost of manufacture that main cause is to transmit sunshine is high, the price of 1 meter is in hundreds of unit left and right, cause holistic cost high, another kind of lower-cost scheme is plastic optical fiber, but plastic optical fiber but exists temperature tolerance poor, power bears the shortcomings such as poor.Therefore at present the main development direction of sunshine leading-in technique be exactly how by cheap fiber optic applications in sunshine import system or find the technology that cost is lower to substitute expensive optical fiber.
In addition, existing sun light lighting technology seldom relates to light regulating technology, makes to utilize the system brightness of sun light lighting to be subject to weather effect larger.
Summary of the invention
The purpose of this utility model is directly to import the deficiencies such as indoor, plastic optical fiber power limited high for the utilization silica fibre cost that throws light on and brightness can not regulate in order to solve existing sunshine, has proposed a kind of adjustable sun light lighting system.
The technical solution of the utility model is: a kind of adjustable sun light lighting system, it is characterized in that, comprise light focusing unit for converging sunshine, for the inwall total reflection straight tube of transfer sun light, connect a plurality of indirectly connected total reflection straight tubes for changing the corner reflector element of optic path direction and for the lighting unit of room lighting; A plurality of total reflection straight tubes and corner reflector element connect to form from outdoor to indoor sunshine transmission channel; Light focusing unit is connected in the outdoor end of sunshine transmission channel; Lighting unit comprises the indoor end optic fibre switching head that is connected in sunshine transmission channel, is connected in the multiple beams of optical fiber on optic fibre switching head and is connected in the luminescence unit of respectively restrainting the optical fiber other end; In sunshine transmission channel, also comprise light modulation unit, described light modulation unit comprises two concentric shafts connection relatively turnable spoke wheel cribbing, one of be fixedly connected with sky sunlight transmission channel inwall, light modulation unit also comprises gobo, and described gobo is connected between the spoke that two wheel brackets are corresponding.
Further, two of described light modulation unit wheeled between between by motor, drive rotation.For regulating the effective aperture of sunshine transmission channel, reach the object of light modulation.
Further, described light focusing unit is Fresnel Lenses.
Further, luminous is convex lens, and wherein the one side of convex lens is plane, and another side is protruding sphere.
Further, described optical fiber is plastic optical fiber.
The beneficial effects of the utility model: adjustable sun light lighting system of the present utility model adopts the total reflection straight tube of tubular structure and corner reflector element to form sunshine transmission channel, and the silica fibre that substitutes traditional cost costliness has been realized the direct import feature of sunshine.After indoor end light splitting, adopt simultaneously plastic optical fiber guaranteed system through-put power and cheaply below advantage the illumination path of indoor complexity arrange, lighting point is set more flexible.System architecture is simple, and later maintenance cost is lower.The wheel bracket of light modulation unit drives gobo to block sunshine transmission channel while relatively rotating, reach the object that regulates luminous intensity.
