Description
Technical field
The present invention relates to stage illumination, lighting technical fields, more particularly, to a kind of stage image with double-colored wheel system
Projection lamp.
Background technology
DLP projector, i.e., digital light processing (Digital Light Procession) projector is a kind of based on DMD
Chip is irradiated in by powerful light source on the image device as image device, and the throwing of projection image is realized with reflected light
Shadow technology.That is image signal is first passed through digital processing by this technology, and then light is projected out.Dmd chip, i.e., it is digital
Micro-mirror element (Digital Micromirror Device) is a CMOS silicon substrate being made of micromirror array.It is each
A micromirror indicates a pixel, drives micromirror rotation by electric signal, controls the gray value of each pixel, micromirror exists
It is imaged under the driving of electric signal, later by projecting frame out by camera lens after the reflection of light source.The projector of DLP technologies has
Primary contrast is high, machine miniaturization, light path uses closed three big features, it can be achieved that pattern scene editor, is commonly used to replace
The projection lamp of traditional fixed pattern piece, to meet the needs of people are for stage-lighting effect.
The colour wheel mainly relied between light source and DMD eyeglasses is presented in the colors of image of DLP projector, and light source passes through color
Wheel, colour wheel carry out color separation to white light, sequentially separate different monochromatic light and penetrate on dmd chip, dmd chip is receiving control panel
Light is emitted on projection screen after control signal.
The light source of DLP Projection Displays is LED light or gas-discharge lamp, and the power density of LED light can not increase substantially；And
Gas-discharge light source is white light, needs first to detach RGB three primary colours lights under the action of colour wheel, then synthesizes and throw via DMD
Project full-color image.Colour wheel is synchronized with DMD rotations, and a kind of color can only be once handled within the same time, and colour wheel carries out color
While switching, DMD carries out image switching, between two kinds of colors switch, can pass through there are two types of light, be imitated in order to not influence image
Fruit, DMD are in " blank screen " state that not will produce image, thus can bring the luminance loss of part, lead to the practical light of colour wheel
Effect is one third, and is hardly higher than 35%.And DMD actual reflectances are about 60%, in this way, maximum light output only has light source to have
Imitate 20% or so of light.So light output is extremely difficult to 5000LM or more, it is difficult to meet need of the special occasions to stage-lighting effect
It asks.
Invention content
In order to overcome the drawbacks described above of the prior art, the stage projection with double-colored wheel system that the present invention provides a kind of
Lamp, it can be achieved that a variety of projection modes switching, the light output amount of projection lamp can be increased, meet the needs of more occasions.
In order to achieve the above objectives, the technical solution adopted by the present invention is as follows：
The convergence component that is set gradually including light source and along light emission direction, spectrum groupware, finishing module, reflected refraction group
Part, prism system, digital micromirror elements and projection lens, the convergence component are parallel for pooling the light that light source is launched
Light, for the spectrum groupware for periodically filtering RBG primaries, the finishing module is described anti-for making light uniformization
Reflected refraction of the refracted component for light is penetrated, the prism system injects light into digital micromirror elements, the digital micromirror elements
It is effective light and invalid light by light reflection, and reflected towards different directions into the prism system, through described for providing image source
After prism system total reflection, effective light projection enters the projection lens imaging, and invalid light then projects other outside projection lens
Direction, the projection lens is by image magnification, and by the image projection of amplification to object, it is characterised in that：The light splitting group
Part is a double-colored wheel system, including the first colour wheel and the second colour wheel, and the first colour wheel is RGBW colour wheels, and the second colour wheel includes white
With several non-white colo(u)r filter, when the first colour wheel rotates, and the second colour wheel is in static white filter or removed light path,
The projection lamp projects full color image；When the first colour wheel is in, white filter is static or removed light path, the second colour wheel quilt
When cutting and turning to the optical filter of any color, the projection lamp projects pure monochrome image projection.
The present invention projector have double-colored wheel system, can realize the projection of both of which, when the first colour wheel rotate, second
When colour wheel is in static white filter or removed light path, the projection lamp projects full color image, can meet common occasion
Demand, be common projection mode.When the first colour wheel is in, white filter is static, and the second colour wheel is cut into and turns to any
When the optical filter of kind color, the projection lamp projects pure monochrome image projection, is Special Projection pattern, at this point, due to subtracting
Unwanted color, there is no " blank screen " phenomenons DMD, and light output amount at this time can reach the 55%-60% of original effective light,
It is 2-2.5 times of common projection mode projector.And the second colour wheel is the combination by white and several non-white colo(u)r filter,
The image projection that can realize a variety of colors manufactures ideal stage effect.If the first colour wheel is used only, when its realization is special
When pattern, since color is only RGB, usage scenario will be caused to be limited, the effect of a projection lamp is difficult to realize a variety of dances
Platform demand.
Preferably, first colour wheel and the second colour wheel are respectively equipped with position sensor, the filter for incuding respective colour wheel
Mating plate position, the switching of implementation pattern.First colour wheel and the second colour wheel are driven by respective driving motor respectively.
Two colour wheels are realized by being each provided with position sensor and driving motor independently of each other, when can be derived that any
Carve respective color position so that certain color wheel can be switched to white or remove light path when needed, implementation pattern switching,
Meets the needs of special occasions.
Preferably, second colour wheel is the filter of one or more colors in white filter and red, orange, yellow, green, indigo, azure, purple
The monochrome image projection of multiple color may be implemented in mating plate under Special Projection pattern.
Preferably, the light source is gas-discharge lamp or white light LEDs or rgb light source or RGBW light sources.
Preferably, if the convergence component is dry lens, the light that light source is launched is pooled into directional light.
Preferably, the finishing module is fly's-eye lens.Fly's-eye lens is to be combined to be formed by a series of lenslets, using double
The uniformity of light can be improved in row's fly eye lens array.
Second colour wheel can also be the combination of several non-white colo(u)r filter, at this point, in order to realize common projective module
Formula, the second colour wheel must be removed light path.
Compared with prior art, the stage projecting light energy implementation pattern switching provided by the invention with double-colored wheel system,
Light output amount under special pattern can reach the 55%-60% of original effective light, be 2-2.5 times of common projection mode projector,
Light efficiency is significantly enhanced, and can realize the image projection of multiple color, the dance of a variety of occasions can be met with a projection lamp
Platform demand.
