HEADLAMP FOR MODEL LIGHTING SCALE

The invention relates to a floodlight in a floodlight system for illuminating scale models as an aid in lighting design and as a teaching aid for lighting design. The system consists of a light source, a dimmer unit, an optical cable 1. optical fiber and 5 miniature projectors. The system can be used to create lighting situations for a scale model and they can be controlled, for example, on a theater light table. Scale modeling is necessary as a communication tool when discussing lighting. Light is energy and its three-dimensional effects cannot yet be otherwise represented.

10 Flashlights, cold mirror lamps, and other spotlights are commonly used to test lights on a scale model. With these devices, only one lighting situation can be tested at a time, for another situation the lights have to be moved to other new places. In addition to the need to move the luminaires from one place to another, the light intensity of these luminaires cannot generally be changed, let alone that the intensities could be stored in the memory of the light control device. The lack of programming and recording capability precludes the use of a scale model for dramaturgical study of light. Examining changes in lighting on paper can lead to erroneous results and erroneous investments.

20 Ordinary miniature projectors and other luminaires can be misleading when looking at a miniature model, as there is no equivalent of these luminaires on a 1: 1 scale, neither qualitative nor quantitative. In order to achieve the lighting achieved in the scale model in reality, giant floodlights would be needed, for example:.: 25 25: 1 models with light properties, if the scale used in the scale model work is 1:25.

Actual floodlights are relatively small in size and power compared to these theoretical giant floodlights. Thus, the lighting achieved in the scale model may not be achievable in reality.

By means of the device according to the invention, a decisive improvement in the above-mentioned drawbacks is obtained. To achieve this, the device according to the invention is characterized by what is set forth in the characterizing part of claim 1.

The device according to the invention can be used to illustrate lighting with the aid of a scale model and therefore the device is at the same time an excellent training tool. With the help of the programmed lighting change times and intensities, the entire lighting program can be presented in a scale model. The color 5 of the light can be determined to correspond to reality with the same filters that are actually used. With the help of the model model made, blunders about the basic choices of lighting and dramaturgy can be avoided in advance. Because the projectors work correctly on a scale, the type, number, and effect of the color filters 10 on the intensities of the required projectors can be determined from the model, while the ratios of the placement of the headlight equipment are clarified. A miniature floodlight can be made to correspond, for example, to a 500-2000W profile floodlight on a scale of 1:25 commonly used in miniature work. Design errors are already corrected in the scale model and the costs of errors are significantly 15 times lower than the costs of actual errors. The plan to be implemented may be more complete and thus postpone the layout of the headlights and the final completion of the lighting program. The appliance is safe to use because it does not heat up and is not electrically operated per se.

The invention will now be described in detail with reference to the accompanying drawings 20.

Fig. 5 shows the principle of the ejector system. The light source (13) is a powerful luminaire with light directed at the end of the fiber optic bundle.

The dimmer unit (14) is located between the light source and the fiber bundle and has a liquid crystal dimmer for each optical fiber, which can be connected to a light control system or the like. The same dimmer can be used as a color changer if the implementation corresponds to a color data transfer projector. The optical fibers (16) are attached to an adapter (15) which aligns the ends of the light source, dimmer and optical fibers.

The optical fibers (16) transmit light to the miniature projector (17).

The two lenses (7) of the Fig. 1 device can be used to focus and change the wedge of the incoming light. The lenses (7) are adjusted to the desired position in the tube (2) by means of the frames (1).

The light wedge can be delimited by iron delimiters (12) through the openings (3). The curbs remain in place by means of the magnet (4). If desired, the delimiters (12) and the magnet-5 rivet (4) can be removed from devices where no delimitation is required. The light is introduced into the device by means of an optical fiber cable (11,16). The ring (5) prevents possible reflections from entering the lens system. The optical cable is fastened to the blank (8) of the projector (6) with a screw (9) to which a joint (10) is attached, on which the device can be directed.
