Full-automatic follow spot light
The utility model relates to stage lamp, is the full-automatic follow spot light that a kind of stage performance and large-scale activity are used.
At present, the follow spot light that stage performance and large-scale activity are used, its structure is roughly the same, comprise base, swivel mount, lamp body have forward and backward end cap on the lamp body, socket, reflector, light source, optical gate, iris diaphragm, colour temperature sheet, color chips, big or small condenser, big or small eyeglass seat and sliding guide.Its level of this follow spot light and vertical rotation, big or small condenser interlock zoom, optical gate, iris diaphragm, colour temperature dish and all moving control of armrest of color chips conversion major part, automatization level is low, can not satisfy stage performance and large-scale activity far away to follow spot light automation, programme-controlled and central controlled requirement.
Summary of the invention
The purpose of this utility model provides a kind of full-automatic follow spot light, and is low to solve the moving control of prior art armrest automatization level, can not satisfy stage performance and the large-scale activity problem to follow spot light automation, programme-controlled and centralized Control requirement far away.
The purpose of this utility model is achieved in that this lamp comprises base, be combined with vertical shaft on the base, the intrinsic swivel mount in its upper end, be combined with lamp body by transverse axis on the swivel mount, before having on the lamp body, rear end cap, socket, reflector, light source, optical gate, iris diaphragm, the colour temperature sheet, greatly, little condenser, greatly, little eyeglass seat and sliding guide, it is characterized in that: at the intrinsic gear wheel in vertical shaft bottom, it is connected with stepper motor axle head pinion by driving-chain, intrinsic stepper motor on swivel mount, on its axle head pinion driving-chain is arranged, the two ends of driving-chain are separately fixed on the lamp body of transverse axis both sides, difference inherent gear on the size eyeglass seat, be connected with stepper motor axle head pinion by driving-chain, eyeglass seat matched in clearance is on sliding guide, intrinsic arc-shaped rack on the iris diaphragm lever change, it is meshed with the stepper motor shaft end gear, color chips is fixed on the colour changing dish, the colour changing dish is fixed on the stepper motor shaft end, colour temperature sheet and pattern segments are fixed on the colour temperature dish, the colour temperature dish, optical gate and stroboscopic sheet are separately fixed at the stepper motor shaft end, and stepper motor leans on support or directly is fixed on the lamp body.
The colour changing dish is disc, and there is motor axis hole at its center, is furnished with 3-8 hole on the concentric circles, on the hole respectively intrinsic red, yellow, blue, green, bletilla is orange, purple cyan sheet.
The colour temperature dish is its center of disc axis hole, is evenly equipped with 2-8 hole on the concentric circles, intrinsic colour temperature sheet on two holes, intrinsic pattern segments on all the other holes.
The stroboscopic sheet is fan-shaped, and unthreaded hole and motor axis hole are arranged above.
The stroboscopic sheet has the 1-2 sheet.
The utility model compared with prior art has the following advantages: (1) this lamp level is leaned on stepper motor with vertical rotation, size condenser interlock zoom is by stepper motor, optical gate, iris diaphragm, colour temperature dish, stroboscopic sheet and the conversion of colour changing dish all drive by stepper motor,, can satisfy the needs of stage performance and large-scale activity fully as long as but stepper motor is connected just individual event function control, programme-control or centralized Control with controller; (2) red, yellow, blue, green and white five kinds of color chips are installed on the colour changing dish, simplify the structure, and have improved the colour changing effect; (3) on the colour temperature dish, pattern segments has been installed, has increased the light pattern effect; (4) replace the bulb flicker with the stroboscopic sheet, prolonged bulb life, satisfied stage performance and large-scale activity requirement light transformation.
