Abstract
A natural light source collimated light device is a collimated light beam tube used for optical device observation, collimation and verification, which is a rectangular tube body circled by metal plates. An anastigmatic objective is equipped inside the metal tube on the left wall above the tube body. A natural light source collection system is positioned on the right wall below the tube body. A turn light path positioned in the tube is arranged by two rectangular triple prisms diagonally. Low-energy diffused light is formed by natural light or laboratory illuminating light through light source collection and photospot and evenly irradiates on target reticule, generating collimated light beam for infinite distance through the turn light path and the collecting objective. The device has the advantages of no need for light bulbs and transformer, energy-saving, powerful light source collection function, even field light, little collimation error, little volume, portability and convenient usage.

Background technology
At present, the domestic directional light beam tube that optical instrument such as telescope etc. was observed, aims at, adorned the school, adjust to use is to utilize the light source of bulb to carry out.This electric light source is to constitute focal distance f by the bulb of 6V/2.1W-8.0W and the elements such as transformer that match thereof ' be 300～1000 centimetres.
Use this device that following defective is arranged:
1, lamp source must be to have the situation of electricity to use, and can't use in case have a power failure;
2, owing to spread of voltage, bulb damages easily;
3, because voltage instability causes the visual field light and shade unclear easily, pointing error appears;
4, because the easy temperature distortion of internal object graticule is managed in long red-hot bulb light illumination, cause the parallel beam drift;
5, because the focal length of parallel beam is big, and the length of parallel light tube is long, volume is big, is unfavorable for being installed on the rotating disc of optical instrument.
The content of utility model
The purpose of this utility model provide a kind of lamp the directional light device, be radiated at equably on the target graticule by the diffused light that light source collection and optically focused form low energy with natural light or laboratory illumination light, form the parallel beam of infinite distance by turn back light path and collecting objective.This device is without bulb and transformer equipment, energy savings.The light source acquisition function of this device is strong, the light of visual field is even, pointing error is few, and volume is little, carries, easy to use.
The technical solution of the utility model is such:
A kind of directional light device of lamp, the rectangle body that surrounds by sheet metal, it is characterized in that being provided with anastigmatic objective in the metal tube of left side wall above body, body below right side wall is provided with the acquisition system of lamp, in pipe, be provided with the light path of turning back, it is to arrange that by two right angle prism diagonal angles right angle prism is fixed on the inboard wall of tube body by supporting seat respectively.
Described natural light acquisition system is provided with 360 ° of angles of rotation and bracket with foldable, the left side arm of support is installed on the tube wall, the left side arm is provided with the light siphunculus, thin frosted glass is housed in the light siphunculus, the front end of thin frosted glass is provided with condenser, the front end of condenser is provided with the target graticule, and the right arm of support is provided with plane mirror, and two side arms is connected by spherical linkage.
The bottom of rectangle body is provided with leg.
By on learn that the technological means that the utility model adopts is:
1, the condenser that uses in this device collection light-source system is two gummed achromatic condensers, guarantees the image quality of target graticule;
2, at the collection light-source system the folding plane mirror of rotatable 360 degree is installed, collection light source function is strong, guarantees highlight flux;
3, set up in lighting system and put thin frosted glass, purpose is to strengthen the diffusion of light effect, improves the optical uniformity of visual field, reduces pointing error;
4, increase the light path of turning back between object lens in this device and the target graticule, the path that can shorten light path, device volume is little, portably uses conveniently.
The utility model has the advantages that:
1, the utility model is taked the light path of turning back, and shortens the contour length of parallel light tube, makes the light path of parallel light tube shorten half than original length on rectilinear direction, brings convenience for use, carrier, also can be placed on the instrument worktable, and resistance to shock is good;
2, utilize the irradiation of natural light or laboratory illumination light, can make a parallel light pipe save 0.4 degree electricity every day, can save 80 degree every year by plane mirror and condenser.China has thousands of as the parallel light tube of run-home at present, calculates with this and is at least national using electricity wisely more than 80,000 degree electricity every year, has saved the energy;
3, this device does not re-use bulb, and every parallel light tube can reduce 50 yuan of costs, can be country every year and cuts down expenses more than 50,000 yuan;
4, the light source of this device derives from natural light, reduces target graticule Temperature Influence, has improved the stability of parallel light tube target, has strengthened pointing accuracy.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein: 1 object lens, 2 rectangle bodys, 3,10 right angle prisms, 4 target graticules, 5 condensers, 6 thin frosted glass, 7 plane mirrors, 8 rotatable, folding racks, 9 legs.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
A kind of directional light device of lamp, it is the rectangle body 2 that is surrounded by sheet metal, the inwall of body 2 is pasted with black light-absorbing paper, is used to absorb diverging light.The bottom of rectangle body 2 is provided with leg 9.Above body 2, be provided with anastigmatic objective 1 in the plastic cement pipe of left side wall.Right side wall below body 2 is provided with the acquisition system of light source.
