Summary of the invention
The present invention regarding to the issue above and technical need, proposes a kind of remote guide-lighting and hot spot direction and sizeControllable display methods.
Technical scheme is as follows:
A kind of remote guide-lighting and hot spot direction and the controllable display methods of size, include the following steps:
Step 1, point light source is issued by light-emitting component, is transmitted to leaded light component, light is controlled by the leaded light componentDivergence range control the size of hot spot；
Step 2, it after the leaded light component receives light source, is transmitted by component internal, light is exported to light directionTransition components；
Step 3, after the light direction transition components receive light, radiation direction is converted, hot spot is transmitted to displayThe display position of screen；
Step 4, according to design requirement, the installation ginseng for determining the leaded light component and the light direction transition components is calculatedNumber.
Its further technical solution are as follows: the leaded light component includes at least one of convex lens and concavees lens, describedLight direction transition components include at least one of plane mirror, concave mirror and convex lens.
Its further technical solution are as follows: the installation parameter includes at least one of installation site, distance, focal length.
The method have the benefit that:
1, it can be realized the light source transmission range of setting.
2, light source transmission direction can control, can be realized at any angle light source output direction,
3, can flexible design light source position and display position and spot size, easily and efficiently utilize complete machine space.
Specific embodiment
The following further describes the specific embodiments of the present invention with reference to the drawings.
Fig. 1 is a kind of remote guide-lighting and hot spot direction provided by one embodiment of the present invention and controllable aobvious of sizeShow the flow chart of method, as shown in Figure 1, this method may comprise steps of:
Step 1, point light source is issued by light-emitting component, is transmitted to leaded light component, the hair of light is controlled by leaded light componentScattered range controls the size of hot spot.
Optionally, leaded light component includes at least one of convex lens and concavees lens.
Illustratively, as shown in Fig. 2, leaded light component is made of convex lens 1 and convex lens 2, the focal length of convex lens 1 is f, hairObject distance between optical element and convex lens 1 is u, and the image distance between convex lens 1 and convex lens 2 is v, and r1 is the crowning radius of object space(positive value), r2 are the crowning radius (negative value) of image space.
Amplify distance by convex lens 1, then by 2 optically focused of convex lens, can achieve the transmission range of needs.
Step 2, it after leaded light component receives light source, is transmitted by component internal, light is exported to light direction and is convertedComponent.
Optionally, light direction transition components include at least one of plane mirror, concave mirror and convex lens.
Illustratively, when light direction transition components are plane mirror, it can use the light reflection principle of plane mirror, pass through oneA or multiple plane mirrors, reach the light output direction of needs.
Step 3, after light direction transition components receive light, radiation direction is converted, hot spot is transmitted to display screenDisplay position.
Step 4, according to design requirement, the installation parameter for determining leaded light component and light direction transition components is calculated.
Optionally, installation parameter includes at least one of installation site, distance, focal length.
The calculation formula of focal length are as follows: f=r1*r2/ (n-1) * (r2-r1), wherein n is refractive index, for example, acrylicRefractive index is 1.5.
Convex lens formula are as follows: u=vf/ (v-f), as u=f, input light source is penetrated in parallel after reflecting via convex lensOut；As u < f, light source and output light are inputted ipsilateral；As f < u < 2f, v > 2f, light source output distance amplification.
It can choose the installation site, distance and focal length of leaded light component in conjunction with above-mentioned formula according to actual design demandDeng, to realize different transmission ranges, obtain different spot sizes, by adjust light direction transition components difference may be implementedHot spot direction.
Remote guide-lighting and hot spot the direction provided in the embodiment of the present invention and the controllable display methods of size, canRealize the light source transmission range of setting, and light source transmission direction can control, and can be realized light source output side at any angleTo, can flexible design light source position and display position and spot size, easily and efficiently utilize complete machine space.
Above-described is only preferred embodiments of the invention, and present invention is not limited to the above embodiments.It is appreciated that thisThe other improvements and change that field technical staff directly exports or associates without departing from the spirit and concept in the present inventionChange, is considered as being included within protection scope of the present invention.
