CN201827822U - Dual-lens condensed light and parallel light transmission sunlamp illuminator - Google Patents

Abstract

The utility model relates to a dual-lens condensed light and parallel light transmission sunlamp illuminator, which comprises a light collector, a light guide pipe, a light energy distributor, a light steering mirror and a diffuse transmission lamp holder and is characterized in that the light collector is formed by combining a large Fresnel convex lens and a small Fresnel convex lens in manner of coaxality and focus coincidence; the large-diameter convex lens collects and gathers sunlight; the gathered sunlight is irradiated to the small-diameter convex lens through a common focus to be refracted into parallel sunlight of which the density is bigger in the unit area through the small-diameter convex lens; then the light distribution is carried out through a light splitter and a reflector which are arranged in the light guide pipe; and the sunlight is transmitted to the diffuse transmission lamp holder through the light steering mirror arranged in a light path. The illuminator can be used for collecting the sunlight in sunny days to windowless rooms like markets, warehouses of office rooms, basements, passages, lavatories, even places like classrooms facing the north and the like to replace electric lamp to illuminate; the excessive sunlight charges a photovoltaic battery, and the photovoltaic battery discharges at night or in cloudy days to illuminate, thereby saving resources like power, coal and the like and reducing the pollution and the greenhouse gas CO2 emission which are caused by coal-fired power generation.

Description

Double lens optically focused, directional light transmission sunlamp lighting device

Technical field

The utility model relates to a kind of double lens optically focused, directional light transmission sunlamp lighting device, is used to gather sunshine and does not have the room illumination of window for the basement or the back.

Background technology

Energy savings reduces carbon emission and become the problem that human civilization progress institute must concern, so the utilization of solar energy more and more causes people's attention.In the field of transmission sunshine, the illumination of optical cable fiber has been arranged, be applied to decorative lighting, back lighting, sensing illumination and pass the picture illumination; Photovoltaic cell accumulation of energy illumination is with behind the solar light focusing, to the photovoltaic cell charging, provides energy to be used for illumination, for example solar street light by photovoltaic cell again; Light pipe transmission illumination is generally taked to utilize light in light pipe internal reflection transmission at inner-walls of duct coating high reflecting material, realizes illumination.

Summary of the invention

The purpose of this utility model is to provide a kind of double lens optically focused, directional light transmission sunlamp lighting device, its be sunny daytime gather sunshine to windowless room such as market, the warehouse of office room, basement, corridor, toilet, even towards the places such as classroom on north, replace lamp lighting, superfluous sunlight charges to photovoltaic cell, evening or when cloudy day discharge lighting, resources such as conservation of power and coal, reduce the pollution that causes because of coal fired power generation and the discharging of greenhouse gases-CO2.

The technical solution of the utility model is achieved in that double lens optically focused, directional light transmission sunlamp lighting device, by lighting device, light pipe, optical splitter, turn light rays mirror and diffuse scattering lamp holder are formed, it is characterized in that: lighting device is made up in mode coaxial and that focus overlaps by small one and large one two Fresnel convex lens, the major diameter convex lens are gathered, assemble sunshine, sunlight after the focusing is radiated on the small diameter lenses through common focus, it is bigger to reflect the unit are upper density through the minor diameter convex lens, parallel sunshine, optical splitter in being located at light pipe again, reflective mirror carries out light and distributes, and is transferred to the diffuse scattering lamp holder by the turn light rays mirror that is located in the light path.

Described diffuse scattering lamp holder is concavees lens or pitted skin glass.

Good effect of the present utility model is to utilize the convex lens can the optically focused principle, by small one and large one Fresnel convex lens, arranges with the focus coincidence system and to make lighting device, the big lens of lighting device are towards the sun, gather sunshine, lenslet connects light pipe, exports highdensity directional light; Utilize light pipe that parallel sunshine is transferred to warehouse, basement, corridor, the toilet of market, office room, even, introduce sun light lighting for these windowless rooms of can not see sunlight on sunny daytime towards the windowless rooms such as classroom on north; Simultaneously to photovoltaic cell charging, at night or the cloudy day throw light on by supplying power for photovoltaic cell; Lighting device is installed in building roof or side, Chaoyang; Light pipe is the aluminium specular light transfer tube that inner surface has high reflectance; Installation can distribute the optical splitter of luminous energy and the deviation mirror that throws light on to different directions to different branch in the pipe; Its terminal i.e. " lamp holder " adopts concavees lens scattering or pitted skin glass to make light soft.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described, as shown in Figure 1, double lens optically focused, directional light transmission sunlamp lighting device, bylighting device 2,light pipe 3, optical splitter 4, turn light rays mirror and diffuse scattering lamp holder are formed, it is characterized in that:lighting device 2 is made up in mode coaxial and that focus overlaps by small one and large one two Fresnel convex lens, the major diameter convex lens are gathered, assemble sunshine, sunlight after the focusing is radiated on the small diameter lenses through common focus, it is bigger to reflect the unit are upper density through the minor diameter convex lens, parallel sunshine, optical splitter in being located at light pipe 34 again, reflective mirror carries out light and distributes, and by be located in the light path with turnlight rays mirror 5 at any angle be transferred to need illumination terminal--6 pairs of windowless rooms of diffuse scattering lamp holder throw light on.

As shown in Figure 1, when sunshine is gathered, assembled to the major diameter convex lens of light source such as sunshine 1process lighting device 2, sunlight after the focusing is radiated on the small diameter lenses through common focus, reflect bigger, the parallel sunshine 1 of unit are upper density through the minor diameter convex lens, be transferred tolight pipe 3 through gathering, focus on the parallel rays that concentrates, is refracted as higher density, inlight pipe 3, transmit in the directional light mode; Need be to the place that different branch distributes luminous energy to throw light on, installation can be regulated the optical splitter 4 of reflective area size, and its principle is to utilize reflective mirror reflective, the size that needs the illumination degree according to different branch, distribute each area towards reflex reflector lens, area is big more, and is reflective many more; Can regulate the turnlight rays mirror 5 of direction in the place installation that needs light to turn, also be reflective mirror, in order to change the light illumination direction; Diffuse scattering lamp holder 6 is concavees lens or pitted skin glass, with the light scattering, makes light softer.
