Description

Description: TECHNICAL FIELD The present invention relates to a track light device used when a reflecting mirror is installed at a predetermined position for collimating with a lightwave distance meter or the like.

(Prior Art) When an electro-optical distance meter is fixed to a target point and a reflecting mirror is installed at a collimation point of the electro-optical distance meter, so-called tracking and staking operations are performed. Move the reflector near the collimation point with the reflector facing the lightwave distance meter,
A reflector is set at the collimation point according to a signal from an operator looking through the telescope.

(Problems to be Solved by the Invention) According to the above-described method, the worker having the reflector and the worker except the telescope have to work at a distance from each other, which is very troublesome. There was a problem that was.

An object of the present invention is to solve the above problems.

(Means for Solving the Problems) In order to achieve the above object, the first invention of the present application is directed to a second invention in which the duty factor is different, and in the same period, when one emits or increases light, the other does not emit or reduces light. The first and second blinking points are emitted at a predetermined divergence angle, and the first and second blinking points are emitted.
Is characterized in that the irradiation range of the flashing light is partially overlapped.

According to a second aspect of the present invention, a light-shielding portion and a light-transmitting portion are alternately arranged along a rotational direction in an annular portion centered on the rotation center of a rotating disk driven by a motor and in a region surrounded by the annular portion. An optical chopper formed so as to have an opposite relationship, and a light source for irradiating light to one main surface of a rotating disk of the optical chopper, and And the second blinking light are obtained.

(Function) In front of the emission direction of the light (visible light), the area irradiated with the first blinking light, the area irradiated with the second blinking light, and the first
And a region to be irradiated with the second blinking light by polymerization. In an area where the first and second blinking lights are superposed and irradiated, the first and second blinking lights have the same cycle, different duty factors, and when one emits or increases, the other does not emit or Because of the dimming, the operator sees continuous light and thus knows that he is now in the collimating direction. However, in the irradiation area of the first or second blinking light, blinking lights having different duty factors enter the eyes of the worker, and therefore, it is known that the user is at a position deviated to one of the collimating directions.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

 FIG. 1 shows an embodiment of the present invention.

In the figure, 1 ₁ and 1 ₂ are both track light device source (visible light), the optical system of the track light device, for example, splitting prism light wave range finder distance measuring optical system and vision mutatis mutandis optical system Provided, the center of the irradiation overlap portion is configured to coincide with the optical axis of the distance measuring optical system, or configured separately from this optical system, the center of the irradiation overlap portion and the optical axis of the optical system It is configured to be parallel. The light source 1 ₁ and 1 ₂ are respectively connected to the power source 3 through the switching circuit 2,
For example, the light source 1 _1, the duty factor as shown in FIG. 2 (A) is emitted light 1/3, the light source 1 ₂ is the duty factor as shown in FIG. 2 (B) 2/3 A pulse voltage such that the light is emitted is applied by the operation of the switching circuit 2. Then, the light source 1 ₁ and 1 ₂ are output through the respective lens 4 from the first and second respective flashing light predetermined divergence angle theta _A, has a theta _B, the slight its optical axis A and B It spreads at an angle φ and overlaps in the range of a small angle γ, and the collimation line of the optical distance meter is located within this range.

Thus, the worker having the reflecting mirror can adjust the divergence angle θ shown in FIG.
When you are in the _A, the flashing light as shown in FIG. 2 (A) enters the eye, when you are in the divergence angle θ in _B enters the eye blinking light shown in FIG. 2 (B), the angle γ i.e. When you are on the line of sight, continuous light enters your eyes.

Thus the light source 1 ₁ to eyes is continuous light when the flashing light as shown in FIG. 2 (A) has entered the eye, 1 ₂ to move to the left toward the flashing light shown in FIG. 2 (B) When enters the eye, it moves to the right until continuous light enters the eye.

 FIG. 3 shows another embodiment of the present invention.

In this embodiment, there is one light source 1 and an optical chopper 4 is arranged in front of the light source 1. The optical chopper 4 comprises a rotating disk 6 driven by a motor 5. The rotating disk 6 is divided into an annular portion 7 centered on the center of rotation and a circular region 8 surrounded by the annular portion 7, and the annular portion 7 is transparent at a fixed length along the rotation direction. Light section 9 ₁ and light blocking section 10 ₁
Are formed in the circular region 8 along the rotation direction.
Transparent portion 9 shielding portion 10 ₂ at a position corresponding to ₁ is formed, the light transmitting portion 9 ₂ is formed at a position corresponding to the light shielding portion 10 _1.
Thus, when one main surface of the rotating disk 6 is irradiated with light from the light source 1, the annular portion 7 of the other main surface passes through the annular portion 7 in FIG.
And the second blinking light shown in FIG. 2B is emitted from the circular region 8.

The first and second flickering lights pass through _two prisms 11 ₁ and 11 ₂ having a trapezoidal cross section that spread outward,
Each has a predetermined divergence angle, so that the two optical axes spread at a slight angle and overlap in a small angle range.

It is also possible to use two prisms 11 _1, 11 ₂ of the lens instead.

(Effect of the Invention) Since the present invention is configured as described above, the observer can know whether the observer is displaced to the right or left with respect to the collimation direction. This has the effect that the reflecting mirror can be quickly installed at the collimation point without the instruction of the worker on the side.
