Description
Technical field
The present invention relates to projection device fields, are to be related to automatic brightness adjustment projector more specifically.
Background technique
The use of projector largely improves the mode of people's communicating questions, but in the process using projector
There is also some inconveniences.One of them is exactly to be not easy to adjust there is projector brightness during using projector
The problem of section.During using projector, it is desirable to which the brightness for adjusting projector is often more troublesome, usually adjusting throwing
After the brightness of shadow instrument, as the variation of external environment is so that brightness is no longer suitable, the teacher such as in school, use process
Often select to adapt to project to adjust external environment brightness in switch lamp, be a kind of usage mode that comparison is inconvenient, this is just
Need a kind of projector that can be capable of automatic regulating lightness with external environment.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, it is automatic to provide a kind of brightness
Adjust projector.
Automatic brightness adjustment projector of the present invention, is achieved, ambient light sensor is placed in by following technical proposals
The projector back side, and by being connected inside data line and power supply line and projector, infrared distance sensor part is placed in throwing
Sensor emission end and receiving end are placed in front of projector surface by shadow instrument casing internal, and ambient light sensor is by ambient light
Line intensity is sent to processor, and distance that measurement obtains is sent to processor by infrared distance sensor, optical sensor and infrared
Distance measuring sensor is in communication with each other with projector internal processor, and processor identifies projector and curtain using infrared return signal
The distance between cloth, external environment brightness data obtained in combining environmental optical sensor, it is suitable that setting projector light source issues
Brightness.
Compared with prior art, the beneficial effects of the present invention are:
1. convenience.It usually can be because of external environment, such as daytime, night, cloudy day, fine day when being demonstrated with projector
Deng so that drop shadow effect is not ideal enough.For the present invention, then can need not then worry, projection during using projector
Instrument can automatically adjust brightness to adapt to environmental change.
2. energy conservation.For the present invention, projector oneself can adjust brightness in use, when extraneous light intensity is darker,
Projector brightness can be turned down, power consumption is reduced.
3. prolonging the service life.While reducing brightness, the heat itself generated also can be reduced accordingly projector, right
For the use of projector light bulb, the loss of light bulb can be significantly reduced, is prolonged its service life.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, ambient light sensor is placed in the projector back side, and by data line and power supply line and projector
Portion is connected, and infrared distance sensor part is placed in projector casing internal, and sensor emission end is placed in receiving end
Ambient light intensity is sent to processor by front of projector surface, ambient light sensor, and infrared distance sensor will measure
To distance be sent to processor, optical sensor and infrared distance sensor and be in communication with each other with projector internal processor, handle
Device identifies the distance between projector and curtain, the external world obtained in combining environmental optical sensor using infrared return signal
Ambient brightness data, setting projector light source issue suitable brightness.
The ambient light sensor: can perceive ambient light situation, and inform that processor automatically adjusts projector light source
Brightness reduces the power consumption of product.It is widely applied currently, this sensor has had in the products such as mobile phone, notebook.It adopts
The energy of projector consumption can be saved to the maximum extent with ambient light sensor.On the other hand, ambient light sensor facilitates
Screen provides the picture of suitable human eye viewing brightness.When ambient brightness is higher, the projector of use environment optical sensor can be certainly
It is dynamic to be tuned into high brightness.When external environment is darker, projector will be tuned into low-light level, realize automatic regulating lightness.
The infrared distance sensor is also different using the intensity for the different reflections that infrared signal encounters obstacle distance
Principle carries out the detection of barrier distance.In the use process of projector, distance projection in application in all cases
The distance of curtain is not unalterable.Infrared distance sensor emits infrared signal from transmitting terminal, after encountering curtain
Reflect passback sensor receiving end.The distance that measurement obtains is sent to processor after processing.Processor is i.e. using red
Outer return signal identifies the distance between projector and curtain, thus external environment obtained in combining environmental optical sensor
Brightness data, setting projector light source issue suitable brightness.
Detailed description are as follows:
(1) ambient light sensor, including ambient light sensor module and and communication module.In view of dust-proof and projector
Itself generates the influence of brightness, this part black shell (in addition to the part for needing to incude light) can be protected, be placed in throwing
The shadow instrument back side, and by being connected inside data line and power supply line and projector.
(2) infrared distance sensor, including infrared distance sensor module and and communication module.Infrared distance sensor portion
Divide and be placed in projector casing internal, sensor emission end and receiving end are placed in front of projector surface.
(3) when projector powers on start-up operation, ambient light sensor and infrared distance sensor are started to work, right
The environment of surrounding measures, and is carried out data feedback at data to the processor part inside projector by communication module
Reason obtains the projector brightness data to match with environment.
(4) projector main body, including power module, processor module, operation button module, light emitting module, power control
Module and communication module.
(5) it after processor module obtains suitable brightness data, is shone by power control module to projector
The regulation of module progress power.
(6) projector light bulb issues the brightness of control environment under power regulation.
The above is only a preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
