Background technology
Present court many employings projection arrangement is demonstrated, and passes through on-the-spot demonstration so that audit everyone can be clear,
Owing in this projection arrangement, luminous intensity is high, therefore, the heat of generation also can be high, if not in time this heat is shed,
It is likely to cause use obstacle.
Content of the invention
The embodiment of the present invention is by providing the projection arrangement of a kind of ventilation and heat, and solving projector in prior art cannot
In time heat is shed, easily cause the technical problem using fault.
In order to solve above-mentioned technical problem, the technical scheme of the embodiment of the present invention is as follows：
A kind of projection arrangement of ventilation and heat, including body, this internal be provided with light source, polarizing beam splitter, drive circuit, optics
Projection lens, speculum, projection focus adjusting mechanism, imageing sensor, polarizing beam splitter is positioned on the output light path of light source, and optics is thrown
Shadow camera lens is positioned in the light path of polarizing beam splitter light splitting, and speculum becomes the first predetermined angle, drive circuit with optical projection lens
Connect light source, polarizing beam splitter, projection focus adjusting mechanism, imageing sensor, arrange between light source and drive circuit and be wound on light source
With the air pipeline on drive circuit.
Further, the fan blowing cold wind connecting air pipeline is also included.
Further, also including gyroscope, described gyroscope connects drive circuit.
The one or more technical schemes providing in the embodiment of the present invention, at least have the following technical effect that or advantage：
Owing to the projection arrangement in this ventilation and heat using light source, polarizing beam splitter, drive circuit, optical projection lens, anti-
Penetrate mirror, projection focus adjusting mechanism, imageing sensor, polarizing beam splitter are positioned on the output light path of light source, and optical projection lens is positioned at
In the light path of polarizing beam splitter light splitting, speculum becomes the first predetermined angle with optical projection lens, and drive circuit connects light source, partially
Shake optical splitter, projection focus adjusting mechanism, imageing sensor, arranges and be wound on light source and drive circuit between light source and drive circuit
Air pipeline, and then in time heat is shed, it is to avoid cause fault.
Brief description
Fig. 1 is the module diagram of the projection arrangement of ventilation and heat in the embodiment of the present invention.
Detailed description of the invention
The embodiment of the present invention is by providing the projection arrangement of a kind of ventilation and heat, and solving projector in prior art cannot
In time heat is shed, easily cause the technical problem using fault.
In order to solve in above-mentioned prior art, below in conjunction with Figure of description and specific embodiment to above-mentioned skill
Art scheme is described in detail.
Embodiments provide the projection arrangement of a kind of ventilation and heat, as it is shown in figure 1, include body 10, body 10
It is inside provided with light source the 101st, polarization optical splitter the 102nd, drive circuit the 103rd, optical projection lens the 104th, speculum and the 105th, project focusing
Mechanism the 106th, imageing sensor 107, polarizing beam splitter 102 is positioned on the output light path of light source 101, optical projection lens 104
In the light path of polarizing beam splitter 102 light splitting, speculum 105 becomes the first predetermined angle, drive circuit with optical projection lens 104
The 102nd, 103 connection light source the 101st, polarizing beam splitters project focus adjusting mechanism the 106th, imageing sensor 107, at light source 101 and driving electricity
Arrange between road 103 and be wound on light source 101 and the air pipeline 108 on drive circuit 103.
In a particular embodiment so that the heat at light source 101 can shed in time, on this air pipeline 105
Passage is set, is wound around heat radiation.
Entrance at vent line 106 arranges the fan blowing cold wind, thus realizes effectively heat radiation, and this projection arrangement also wraps
Including gyroscope, this gyroscope connects drive circuit 103, and this gyroscope can detect the state of current body 10, if level, just
In regulating this optical projection lens 104, the light that light source 10 sends, through polarizing beam splitter 102 beam splitting, reaches optical projection lens
105, it is then reflected the reflection of mirror 105, the projection image to optical projection lens 105 projection lamp for the focus adjusting mechanism 106 is adjusted
Jiao, imageing sensor 108, for according to image display condition, determines whether to be in normal operating conditions, is being not on
During normal operating conditions, prompting is reported to the police.
This speculum 106 becomes the first predetermined angle with optical projection lens 105, thus avoids the occurrence of " ghost " phenomenon.
By above-mentioned technical scheme, this projection arrangement can be dispelled the heat in time, it is to avoid use fault.
Although preferred embodiments of the present invention have been described, but those skilled in the art once know basic creation
Property concept, then can make other change and modification to these embodiments.So, claims are intended to be construed to include excellent
Select embodiment and fall into all changes and the modification of the scope of the invention.
Obviously, those skilled in the art can carry out various change and the modification essence without deviating from the present invention to the present invention
God and scope.So, if these modifications of the present invention and modification belong to the scope of the claims in the present invention and equivalent technologies thereof
Within, then the present invention is also intended to comprise these changes and modification.
