Abstract
The utility model discloses a light collecting device with a reflective sheet. The light collecting device with the reflective sheet comprises a light collecting cover, the reflective sheet located inside the light collecting cover, and a light guide tube connected with the light collecting cover. A diffuser is connected with the tail end of the light guide tube. The light collecting cover is made of a hemispheric transparent material which is located on a roof and used for collecting light. The reflective sheet is arranged inside the light collecting cover and faces southwards. The light guide tube is made of a high-reflectance circular tube. According to the light collecting device with the reflective sheet, the reflective sheet installed inside the light collecting cover is utilized, the inclination angle of the reflective sheet is set according to the locale latitude, low-angle sunlight in the morning or in the evening is reflected into a light guide tube system, light collection is not affected when sunlight irradiates orthogonally at noon, luminous flux collected within a whole day is maximum, the number of reflection times of light in the transmission process after light enters the light guide tube can also be reduced, and therefore the light efficiency of the light guide tube light collecting system is improved.
Description
Technical field
The utility model relates to a kind of lighting equipment, especially a kind of lighting equipment with reflector plate.
Background technology
At present, in the energy day by day nervous today, light pipe lighting system has been used in building at home and abroad in a large number, and using light pipe daylighting is a kind of technology of energy-conservation and environmental protection.But light pipe daylighting also has an obvious deficiency, and one is to be used in daytime, and another deficiency is exactly that lighting efficiency is too low.How to improve lighting efficiency is the problem that this area will solve always, and a direction is to improve the physical attribute of material, and another direction is exactly the project organization of improvement optimizing product.
In improvement lighting structure, the lighting structure of optimizing dome skylight is the important content of this problem always, also has up till now the patent of many this respects.Sum up main point two kinds of structures, one is active lighting structure, and one is passive lighting structure.
But, although initiatively lighting structure efficiency improves greatly, need additional power source, make cost generally higher, do not meet the original intention of light pipe daylighting yet.Passive lighting structure efficiency is lower, but cost is lower, is easy to install and use.Its project organization is all generally at the inner reflector plate of installing of dome skylight, determines its direction and inclination angle according to geographical position, and effect is better, therefore generally application in most of engineering.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lighting equipment with reflector plate, utilize several reflecting light piece devices of placing successively, increase and enter the luminous flux of light pipe system and optimize light transmission direction, thereby improve the lighting equipment with reflector plate of the efficiency of light pipe lighting system.
The utility model is achieved through the following technical solutions: a kind of lighting equipment with reflector plate, comprise dome skylight, be positioned at the reflector plate of dome skylight inside, and the light pipe being connected with this dome skylight, described light pipe end is connected with diffusing globe, described dome skylight is to be positioned at roof to make for the hemispherical transparent material of daylighting, described reflector plate be arranged at dome skylight inside towards south to, the pipe that described light pipe is high reflectance is made.
As preferred technical scheme, described reflector plate arranges inclination angle according to local latitude.
As preferred technical scheme, described reflector plate divides by 3 to 5 equidistantly to be installed.
As preferred technical scheme, described reflector plate adopts high reflectance aluminium flake material to make.
As preferred technical scheme, described diffusing globe is made up of transparent material
The beneficial effects of the utility model are: the lighting equipment of the utility model band reflector plate, utilization is arranged on the reflector plate of dome skylight inside, the inclination angle of reflector plate is set according to local latitude, reflection morning or at dusk more low-angle sunshine enter light pipe system, and do not affect daylighting when noon, sun light positive was penetrated yet, reach the luminous flux maximum gathering in time a whole day, also can reduce light and enter the order of reflection in transmitting procedure after light pipe, thereby improve the light efficiency of light pipe lighting system.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of the lighting equipment with reflector plate of the present utility model;
Fig. 2 is the lighting equipment reflector plate structure side schematic view with reflector plate of the present utility model;
Fig. 3 is that the lighting equipment reflector plate structure with reflector plate of the present utility model stands to schematic diagram;
Fig. 4 is that the lighting equipment reflector plate structure with reflector plate of the present utility model is bowed to schematic diagram.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of lighting equipment with reflector plate, comprise dome skylight 1, with the reflector plate 5 that is positioned at dome skylight inside, the light pipe 2 being connected with this dome skylight, the diffusing globe 3 that light pipe end connects, described dome skylight 1 is to be positioned at the hemispherical transparent material of roof 4 for daylighting, described reflector plate 5 is to be positioned at dome skylight inside towards south to the high reflectance aluminium flake of installing, described light pipe 2 is inner pipes for high reflectance, and described diffusing globe 3 is that light is broken up for room lighting transparent material.The lighting equipment of the utility model band reflector plate, utilization is arranged on the reflector plate of dome skylight inside, the inclination angle of reflector plate is set according to local latitude, makes to enter luminous flux maximum and the optimization of light transmission direction of light pipe system, thereby improve the light efficiency of light pipe lighting system.
Fig. 2 is the lighting equipment reflector plate structure side schematic view with reflector plate of the present utility model, and Fig. 3 is that reflector plate structure stands to schematic diagram, and Fig. 4 is that reflector plate structure is bowed to schematic diagram.
The beneficial effects of the utility model are: the lighting equipment of the utility model band reflector plate, utilization is arranged on the reflector plate of dome skylight inside, the inclination angle of reflector plate is set according to local latitude, reflection morning or at dusk more low-angle sunshine enter light pipe system, and do not affect daylighting when noon, sun light positive was penetrated yet, reach the luminous flux maximum gathering in time a whole day, also can reduce light and enter the order of reflection in transmitting procedure after light pipe, thereby improve the light efficiency of light pipe lighting system.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
