- the positioning of the gopo 9-2 inserted into the gap between the fixed substrate 42 and the gopo holding plate 44 is determined by the centering projection 53 formed on the fixed substrate 42. Is what you do.
- the insertion of the gopo 9-1 and 9-2 is not limited to the method of operating the upper and lower sides separately as described above, and the gopo holding plate is operated by operating the upper and lower sides simultaneously.
- the entirety of 4 4 may be separated at a stroke, and gobos 9-1 and 9-2 may be inserted into the gaps created thereby.
- the holder 8 on which the gopo 9-1 or 9-2 is set is inserted into the holder receiver 10 of the lamp 2 of the lighting device 1 and the force for setting the holder 8 is two.
- the gopo insertion portion is provided at a certain interval (for example, approximately 7 mm of display), has a certain thickness, and has the holder 8 in which direction (the surface into which the gobo is inserted is placed on the bulb 3 side). Or the lens 5b side) can be inserted into the holder receiver 10. Therefore, by changing the direction of inserting the holder 8 into which the gopos 9-1 and 9-2 are inserted and set with respect to the holder receiver 10, the image of the gopo 9-1 and 9-2 to be projected is formed. Can be sharpened or blurred.
- the lighting device according to the present invention has the following effects because it is configured as described above.
- the lens moves back and forth at a predetermined pitch due to the combination of the gears and the rack, making it easier to make fine adjustments than conventional slide-type adjustment mechanisms, and the knob may be inadvertently moved like a conventional slide type.
- the use of a cam-type lever makes it possible to switch between fixing and moving the lens by one-handed operation, and the lens movement is performed by one-handed operation just by rotating the operation knob, requiring skill. And the adjustment of the lens position can be performed simply and accurately.
- the position of the operation knob serves as an indication of the lens position, and the lens position can be recognized without the need of providing an additional indicator or the like, and there is an effect that the possibility of mistakenly moving the lens is reduced.
- the weight of the lens barrel is lighter than that made of metal, and even if the support fulcrum by the support arm is set to the lamp house side, the support balance of the lamp body is improved compared to the past, and the tilt angle of the light projection (tilt angle) (Angle) is improved.
- the gap between the front and rear half of the reflector causes convection through the inside and outside space of the reflector, improving the heat dissipation effect around the reflector, and without affecting the optical characteristics, This can prevent phenomena such as cracking of the base material of the reflector and peeling of the coating material due to the reflection.
- the gopo can be easily positioned. ',
- the operation of moving the gopo holding plate in the direction away from the opposing fixed substrate can be performed easily and easily.
