Description
Technical field
The present invention relates to sun light lighting field, more particularly to a kind of optical system of beam condensing unit.
Background technology
When being used up as energy such as the oil of traditional energy, natural gas, coal, water sources, and human being's production life
The leading energy is still these energy, and the mankind will be unable to survive.In following development, the mankind have to look for new energy substitution this
The energy that will be exhausted a bit.It is known that solar energy is the most strong natural resources of most typically, energy, be no expense, it is inexhaustible,
The nexhaustible energy, but an only seldom part injects interior by glass, skylight, it is most of with passage in vain.
When the current whole world all suffers from energy crisis, how more rationally, solar energy is better profited from, is that each state is all asked what is sought
Topic.In modern building, especially urban skyscraper, often there are a lot of rooms that can not see sunlight throughout the year, even if outside is positive
Light illuminates, and interior is also illuminated using artificial light sources, to meet the deficiency of daylighting.Basement, subway, underpass,
Market place builet below the ground, tunnel etc. are even more then that can not see sunlight.Science proves that natural sunlight is very useful to health and environment,
And in the environment of available light illumination, people's health, energetic, notice enhancing, work efficiency also can be greatly
Improve.At present, collection sunlight of the prior art, which introduces indoor device, generally all includes sunlight beam condensing unit, optical transport dress
Put, several parts such as sunshine tracking control device, two ranges of exposures are limited or insufficient and market very little；Huge structure complexity,
Function is single, installation inconvenience and be unfavorable for marketing use, and some products then due in structure the defects of be not suitable at all
In practical application, transmission range is short, does not have use value.
The content of the invention
According to the above deficiency, the present invention provides a kind of beam condensing unit simple in structure, small, light utilization is high
Optical system.
To achieve the above object, the optical system of beam condensing unit of the present invention, main contents are：Including convex lens, speculum
And optical fiber, it is characterised in that the convex lens is made of plastics, and convex lens surface scribbles anti-reflection film, and the speculum is rotation
Parabola, speculum bottom dead center position are equipped with mounting hole, and the optical axis of the convex lens and the optical axis of speculum are straight in same
On line, the optical fiber is installed on by sealing ring in the mounting hole of mirror center position.
Preferably, the optical fiber is hollow net structure.
Preferably, it is coated with reflective film in the mirror surface.
Present invention has the advantages that：Simple in structure, small, raising luminous energy utilization rate, therefore there is wide application
Prospect.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Description of reference numerals：
1- convex lenses, 2- speculums, 3- optical fiber.
Embodiment
The specific embodiment of the invention is described with reference to the accompanying drawings and embodiments：
Embodiment, is shown in that attached drawing 1, a kind of optical system of beam condensing unit, including convex lens 1, speculum 2 and optical fiber 3, its feature exist
In the convex lens 1 is made of plastics, and 1 surface of convex lens scribbles anti-reflection film, and the speculum 2 is the paraboloid of revolution, speculum
2 bottom dead center positions are equipped with mounting hole, and the optical axis of the convex lens 1 and the optical axis of speculum 2 are on same straight line, the light
Fibre 3 is installed on by sealing ring in the mounting hole of 2 center of speculum.
Preferably, the optical fiber 3 is hollow net structure.
Preferably, it is coated with reflective film on 2 surface of speculum.
The preferred embodiment for the present invention is explained in detail above in conjunction with attached drawing, but the invention is not restricted to above-mentioned implementation
Mode, within the knowledge of a person skilled in the art, can also be on the premise of present inventive concept not be departed from
Make a variety of changes.
Many other changes and remodeling can be made by not departing from the spirit and scope of the present invention.It should be appreciated that the present invention is not
It is limited to specific embodiment, the scope of the present invention is defined by the following claims.
