Abstract
A kind of combination unit of the use LASER Light Source of projecting apparatus, including one first blue laser array, a condenser lens, one first speculum, a fluorescent wheel；The multi beam blue laser that the first blue laser array is sent reaches the fluorescent wheel after passing sequentially through the condenser lens, the speculum, and required gold-tinted is inspired by the fluorescent wheel.The present invention more rationally can efficiently utilize the output brightness of LASER Light Source, and can be introduced directly into all kinds of optical projection systems, substitute conventional light source combination unit and use.
Description
Technical field
The invention belongs to the technical field of projecting apparatus illuminant combined device, and in particular to a kind of use of projecting apparatus swashs
The combination unit of radiant.
Background technology
Continuing to develop and innovating with porjector technology, more environmentally-friendly solid light source progressively substitutes projection at present
Ultrahigh pressure mercury lamp or halogen light source that instrument is generally used.Laser-projector is also therefore as the production that can not be despised in Engineering Market
Category type, and following development potentiality in market is very big.
Extra long life can be not only provided using the projecting apparatus of LASER Light Source, can also possess more preferably color, picture is lifted
Expressive force.Therefore it provides a kind of reasonable in design, high brightness, the combination unit of high performance use LASER Light Source, rational to utilize
Existing LASER Light Source, is one of important problem that field scientific research technical staff is badly in need of solution.
The content of the invention
The technical problems to be solved by the invention are a kind of combination unit for the use LASER Light Source for providing projecting apparatus,
The output brightness of LASER Light Source more rationally can be efficiently utilized, and all kinds of optical projection systems can be introduced directly into, substitute conventional light source group
Attach together to put and use.
What the present invention was realized in：
A kind of combination unit of the use LASER Light Source of projecting apparatus, including one first blue laser array, a focusing are thoroughly
Mirror, one first speculum, a fluorescent wheel；
The multi beam blue laser that the first blue laser array is sent passes sequentially through the condenser lens, the speculum
After reach the fluorescent wheel, required gold-tinted is inspired by the fluorescent wheel.
Further, in addition to one second blue laser array, one second speculum, a semi-transparent semi-reflecting lens；Described second
Blue laser array is oppositely arranged with the first blue laser array, and phase shifting；
The multi beam blue laser that the first blue laser array is sent passes sequentially through the semi-transparent semi-reflecting lens, described second
Speculum, the multi beam blue laser that the second blue laser array is sent passes sequentially through second speculum, described semi-transparent
Semi-reflective mirror, reaches fluorescent wheel after the condenser lens, first speculum are then imported together, is excited by the fluorescent wheel
Go out required gold-tinted.
Further, the fluorescent wheel is replaced by a fluorophor.
The advantage of the invention is that：The output brightness of LASER Light Source is more rationally efficiently utilized, and DLP can be importing directly into
Optical projection system, after transmission illumination system, colour wheel, dmd chip, projection lens, can efficiently realize projection imaging.Also can be direct
3LCD optical projection systems are imported into, fluorescent wheel only need to be substituted for the similar fluorophor of principle, this fluorophor causes blue laser
Gold-tinted can be not only inspired after gold-tinted and blue light are combined into white light simultaneously, then passed through poly-lens combination, PBS, divide
After light unit, Polarizer and liquid crystal board combination, prism assemblies, projection lens, projection imaging can be efficiently realized.
Brief description of the drawings
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the single laser light source combination unit structural representation of the present invention.
Fig. 2 is the combination unit structural representation of the double laser light source synthesis of the present invention.
Fig. 3 is that the double laser light source combination unit of the present invention is applied to the principle schematic of DLP projection system.
Fig. 4 is that the double laser light source combination unit of the present invention is applied to the principle schematic of 3LCD optical projection systems.
Embodiment
As shown in figure 1, a kind of combination unit 100 of the use LASER Light Source of projecting apparatus, including one first blue laser
Array 1, a condenser lens 2, one first speculum 3, a fluorescent wheel 4.
The multi beam blue laser that first blue laser array 1 is sent reaches glimmering after passing sequentially through condenser lens 2, speculum 3
Halo 4, required gold-tinted is inspired by fluorescent wheel 4.
Further, in order to realize higher brightness, it would however also be possible to employ the combination of double laser light source.As shown in Fig. 2
A kind of combination unit 200 of the use LASER Light Source of projecting apparatus, including one first blue laser array 1, a condenser lens 2,
One first speculum 3, a fluorescent wheel 4, in addition to one second blue laser array 5, one second speculum 6, a semi-transparent semi-reflecting lens
7。
Second blue laser array 5 is oppositely arranged with the first blue laser array 1, and phase shifting；First blueness swashs
The multi beam blue laser that optical arrays 1 are sent passes sequentially through semi-transparent semi-reflecting lens 7, the second speculum 6, and the second blue laser array 5 is sent out
The multi beam blue laser gone out passes sequentially through the second speculum 6, half transflection mirror 7, and condenser lens 2, first is then imported together and is reflected
Fluorescent wheel 4 is reached after mirror 3, required gold-tinted is inspired by fluorescent wheel 4.So as to obtain the laser of higher energy, realize higher
Brightness.
In addition, the present invention directly can replace traditional projector light source to combine the unit, it is adaptable to DLP projection system and 3LCD
Optical projection system.
As shown in figure 3, the present invention can be importing directly into DLP projection system 300, by transmission illumination system, colour wheel, DMD cores
After piece, projection lens, projection imaging can be efficiently realized.
As shown in figure 4, the present invention can also be importing directly into 3LCD optical projection systems 400, only fluorescent wheel 4 need to be substituted for principle
Similar fluorophor 8, this fluorophor 8 causes blue laser not only to inspire gold-tinted after simultaneously by gold-tinted and blue light
White light is combined into, then by poly-lens combination, PBS, spectrophotometric unit, Polarizer and liquid crystal board combination, prism assemblies, projection lens
After head, projection imaging can be efficiently realized.
Above-described embodiment and schema and non-limiting product form of the invention and style, any art it is common
Appropriate change or modification that technical staff is done to it, all should be regarded as not departing from the patent category of the present invention.
