Description
Technical field
The present invention relates to a kind of laser beam for full-color laser computer head moving lamp and close the light dodging device, belong to the laser demonstration application.
Background technology
Computer head moving lamp has become requisite instrument in stage performance as a kind of important means of setting off atmosphere, manufacture spot effect by contrast.Its advantage is that lamp body rotates the drive beam motion, and slewing area is large, can accomplish 360
0Rotation.This movement effects can produce the pure visual experience of charm before the lights.The tradition Computer lamp uses metal halide lamp as light source mostly, and electrical power is higher, and the Computer lamp power of some high brightness has even surpassed 2000W.Modern stage effect not only needs to use light to embody clear bright design, more needs marvellous, impressive effect light fixture set off by contrast, intersperse and play up.And that laser has is bright-colored, brightness is high, good directionality, the advantage such as energy-conservation, looks the sensation that has more magical illusion.The laser computer head moving lamp utilizes laser as light source, have advantages of power low, without ultra-violet radiation be difficult for loss.
Existing powerful full-color LASER Light Source adopts the laser instrument combination of many different colours, need to close the light colour mixture to Laser output and process.What at present laser lamp generally adopted is the scheme that double wave ankylose mating plate and three-wavelength close the discrete optical elements such as mating plate, but long-term use meeting is because the light light beam that closes that stability problem makes to export produces the phenomenons such as look limit, color be apprehensive.And the lamp body 360 of shaking the head
0Rotatablely move, vibration influence more makes this scheme can't realize commercialization.To close the light technology be only also that the full-color laser of output exists colored limit and serious speckle phenomena after certain optical system by optical-fiber bundling encapsulation to existing optical fiber in addition.And the coupled fiber of hundreds of microns fibre cores also can't adopt ripe optical fiber splitter scheme to carry out light beam to close light.
Summary of the invention
In order to overcome prior art, at multi-beam laser, close the even deficiency that exists aspect smooth of light, provide a kind of laser beam for full-color laser computer head moving lamp to close the light dodging device.
Technical scheme of the present invention is that a kind of laser beam for full-color laser computer head moving lamp closes the even light dress of light
Put, it is characterized in that, this device comprises full-color LASER Light Source, closes bundle optical fiber, mixed light optical fiber and disperse head,
Described full-color LASER Light Source is by the laser constitution of many different colours, and the power output of the laser instrument of different colours can be regulated respectively; The described bundle optical fiber that closes is comprised of many coupled fibers, and the laser coupled of each laser instrument output enters the coupled fiber of a correspondence, and the other end of all coupled fibers is spatially evenly distributed, and is packaged together and becomes the output that closes bundle optical fiber; Described mixed light optical fiber is single coupled fiber, and its fibre core is with to close bundle fiber-optic output circumcircle size suitable, and with the output connection encapsulation that closes bundle optical fiber together.The output of different colours laser enters mixed light optical fiber by closing bundle optical fiber, and mixed light optical fiber comprises the laser of different colours the full-color laser of white light by the synthetic output of addition colour mixture method; Described disperse head is by many fibre cores, to be the intensive combination of short fiber of 10 ~ 100 microns, and its effect is by the described full-color laser homogenizing output of input.
Described full-color LASER Light Source, employing be air-cooled all solid state laser or semiconductor laser, or ld pumping solid state laser, or the combination of semiconductor laser, ld pumping solid state laser.
The color combination of described full-color laser instrument is ruddiness, green glow, blue light, or ruddiness, blue light, gold-tinted, or ruddiness, green glow, blue light, gold-tinted, or by addition colour mixture, synthesizes the full-color output that comprises white light.
The described bundle optical fiber that closes, be comprised of many coupled fibers, and the fibre core of coupled fiber is 100 ~ 1000 microns.
The invention has the beneficial effects as follows, because the technical program is that the light beam of laser instrument output is synthesized together by optical fiber, middle without discrete optical element, solved on the one hand environment steam and dust to the pollution effect of laser optical path, also guaranteed that on the other hand full-color laser beam can not be subjected to computer head moving lamp body 360
0The vibration influence that rotatablely moves.Adopt mixed light optical fiber and disperse head to guarantee to close the uniformity of light light beam, and eliminated serious light beam speckle.
The accompanying drawing explanation
Fig. 1 is that laser beam closes the even smooth schematic diagram of bundle;
Fig. 2 is the three-in-one bundle optical fiber schematic diagram that closes;
