Sunshine to be gifted mankind's treasure as the Nature, is a kind of inexhaustible, the green energy resource not to the utmost of use, while be also the light source adapted to the most during mankind's long-term evolution process is crossed.The utilization of natural light is also subject to the attention of more and more people, and along with the effort of scientific and technical personnel's more than ten years, current lighting technique reaches its maturity.
Existing lighting system is generally divided into three parts: one, daylighting district: by lighting equipment, the natural daylight import system of outdoor is inner; Two, transmission range: carry out light long-distance communications by light pipe or optical fiber; Three, diffusive regions: natural daylight is irradiated to indoor uniformly by diffusing globe.
Although existing light pipe lighting technique comparative maturity, many facilities are brought to human lives, but existing lighting system also exists following problem: 1. in existing lighting system light transmission process adopt light pipe or optical fiber, need at substantial natural resources when producing light pipe and optical fiber and cost is higher more.2. under same illumination intensity demand condition, the installing space required for light pipe is larger, takes up room many.
Utility model content
There is the light pipe of light transmition for existing lighting system and optical fiber cost high, the source expending nature in production process is more, and the problem that light pipe requirements of installation space is larger, the utility model discloses a kind of lighting system, it can be the light prescription dosage regulating device of light beam by light secondary focusing that this lighting system is provided with, make natural daylight with light beam to indoor propagation, light transmition process is without the need to light pipe or optical fiber.The technical solution of the utility model is as follows:
A kind of new and effective lighting system, comprise the light receiver be located at outdoor light and gathered focusing arrangement and be located at indoor, and be located at the light diffusion device that indoor one end is connected with light receiver, it is characterized in that: described light gathers focusing arrangement and comprises dome skylight and be arranged on the collection lens that sunray can be focused on dome skylight, is provided with the light modulator that sunray focus adjustment can be become light beam below described dome skylight; Light beam through light modulator injection to be received to indoor propagation by light receiver device; Described light diffusion device is made up of light reflection cover, light compensating apparatus, diffusing globe, and light compensating apparatus is located on the inwall of light reflection cover, and diffusing globe is connected with light reflection device one end away from light receiver.
Further, described dome skylight is hemispherical, is provided with mounting seat below dome skylight, is provided with through hole in the middle part of described mounting seat, and dome skylight is installed in mounting seat middle through-hole one end open; Described light modulator is set up in through hole, and light modulator can move along the axis of through hole the diameter regulating light beam, and the light beam after light modulator adjustment is penetrated by the through hole other end in the middle part of mounting seat.
Further, the collection lens on described dome skylight are provided with multiple, and multiple collection lens are covered with the hemisphere face of whole dome skylight.
Further, described light gathers between focusing arrangement and light receiver, and the propagation path of light beam is also provided with the reflecting prism that can change light transmition direction.
The utility model beneficial effect: the 1. collection lens on this lighting system dome skylight are covered with the hemisphere face of whole dome skylight, makes a kind of lighting system also have good collection effect to low angle sunshine.2. be provided with light modulator in the collection focusing arrangement of a kind of lighting system, light can be made to be transformed into light beam, propagate with beam pattern, avoid the use of light pipe and optical fiber, reduce costs, save the source of nature.3. the light in this lighting system is propagated with light beam, and the diameter range of light beam is adjustable, and the diameter of light beam is less, takes up room less in beam propagation process.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
The new and effective lighting system of one as shown in Figure 1, it is provided with a mounting seat 7, is provided with a through hole in the middle part of mounting seat 7, and the dome skylight 4 of this kind of lighting system is covered in the upper end open place of mounting seat 7 middle through-hole.Dome skylight 4 is in being hemispherical housing, and the sphere of dome skylight 4 is provided with multiple collection lens 5, and multiple collection lens 5 are covered with the hemisphere face of whole dome skylight 4, such design, make the utility model also have extraordinary collection effect for low angle natural daylight.In the below of dome skylight 4, in through hole in the middle part of mounting seat 7, also erection has light modulator 6, light modulator 6 can carry out short-distance movement by the vertical direction, sunshine once focuses on by multiple collection lens 5, sunlight after focusing on is projected to light modulator 6, light modulator 6 by once focus on after sunshine carry out secondary focusing adjustment, finally make sunshine become light beam 8, sunshine propagated with the form being similar to laser beam.And light modulator 6 can vertical direction move, the diameter of light beam 8 can be regulated, the propagation distance of light beam 8 space size required on propagation path and light beam can be adjusted because of actual environment, and outdoor sunshine is carried to indoor with the form of light beam 8, then compare with fiber-optic lighting system with existing utilization light pipe, there is lifting in essence, make lighting system of the present utility model without the need to setting up light pipe or the optical fibers of light conveying, save a large sum of cost, also save natural resources, and the diameter of light beam 8 is smaller, the space making light-conducting system of the present utility model required in indoor location process is smaller, then greatly improve the scope of application of the present utility model.
The propagation path of light beam 8 is also provided with the reflecting prism 9 that can change light beam 8 direction of propagation, in actual life, when light-conducting system is installed, light collection and light diffusion device are not point-blank, so reflecting prism 9 can meet the needs of the utility model complex situations in actual installation process.The end that light beam 8 is carried is provided with light receiver device 2, because light beam 8 has aggregation, then needs light receiver device 2 to regulate, makes light beam 8 become scattered light.The light diffusion device 3 being provided at the utility model end be connected with light receiver device 2, light diffusion device 3 is by light reflection cover 10, light compensating apparatus 11, the upper end open that diffusing globe 12 forms light reflection shield 10 is connected with light receiver device 2, light compensating apparatus 12 is located on the inner surface of light reflection cover 10, diffusing globe 12 is installed in the one end open of light reflection cover 10 away from light receiver device 2, light beam 8 receives the scattered light of gained after scattering through light receiver device 2, scattered light is reflected by light reflection cover 10 to be propagated to diffusing globe 12, last light is after diffusing globe 12, become soft uniform light to indoor propagation.Light compensating apparatus 11 includes light compensating lamp and light-sensitive element, if when light is too weak, light compensating lamp lights, makes lighting system of the present utility model reach the light intensity requirement of illumination, realizes all-weather of the present utility model and uses.
