Abstract
The invention provides a projection machine. The projection machine comprises a light machine engine, a detector and a control unit. The light machine engine comprises a light source for making the light machine engine generate projection beams. A space through which the projection beams pass is defined as a projection area; and an area covering or overlapping the projection area is a warning area. The detector is used for detecting whether a life body is in the warning area. The detector generates detection signals when detecting that a life body is in the warning area. The control unit controls the projection machine to enter a protection mode when receiving the detection signals, so as to avoid the light source causing damage to the life body.

Embodiment
Relevant aforementioned and other technology contents, characteristics and effect of the present invention in the detailed description below in conjunction with reference to the accompanying drawings embodiment, can clearly present.
Fig. 1 is the block diagram of projector of the present invention.Projector 100 comprises optical machine engine 114, detecting device 104 and control module 106.Optical machine engine 114 comprises light source 102, uses so that optical machine engine 114 produces projected light beams.The definition space that projected light beam is passed through is a view field.Detecting device 104 is responsible for detecting in the caution zone of projector whether life entity is arranged.If detect in the caution zone life entity is arranged, detecting device 104 produces detection signal 112 to control module 106.Control module 106 receives will be controlled projector 100 behind the detection signal 112 and enter protected mode, damage to avoid 102 pairs of life entities of light source.
Detecting device 104 can be infrared ray sensor (IR sensor) or recognition of face video camera.Infrared ray sensor can detect the object near temperature (30～40 degree Celsius approximately).The recognition of face video camera can CCD camera be realized, comprising CCD camera and recognition unit.The filming image that CCD camera will be warned the zone gets off and is sent to recognition unit.Recognition unit is responsible for discerning whether people's face is arranged in the image, is arranged in the caution zone to judge whether the someone.
In other embodiments, light source 102 can be a high-pressure sodium lamp.Because high-pressure sodium lamp needs the long on time, so projector of the present invention is more at high-pressure sodium lamp design optical attenuator component 108.Control module 106 will detect the caution zone at detecting device 104 to be had life entity time control optical attenuator component 108 blocks light source 102.
In other embodiments, projector 100 of the present invention further comprises loudspeaker 110.Detecting device 104 has detected life entity and has entered when warning the zone, and control module 106 will be controlled loudspeaker 110 and send the caution sound equipment.
In other embodiments of the present invention, the caution zone is designed to the view field greater than projector.Fig. 2 is the synoptic diagram of caution zone and view field.The image of projector 202 can be presented in the view field 204.Human eye is if be exposed in the view field 204, and the light beam that very easily suffers direct projection to go into eyes is burnt.Present embodiment will warn the zone 206 be designed to bigger than view field 204, with the performance warning in advance function.In this class embodiment, to enter caution regional 206 the time when detecting device 104 has detected life entity, and control module 106 military order loudspeaker 110 send the caution sound equipment.If light source 102 is laser instruments, control module 106 will detect at detecting device 104 and close light source 102 when life entity enters view field 204.If light source 102 is high-pressure sodium lamps, control module 106 will block light source 102 by control optical attenuator component 108 when detecting device 104 has detected life entity and enters view field 204.
The present invention more provides a kind of method of operating, is applicable to projector.Projector comprises optical machine engine 114, detecting device 104 and control module 106 as shown in Figure 1.Optical machine engine 114 comprises the light source 102 of being responsible for projection, uses so that optical machine engine 114 produces projected light beams.The definition space that projected light beam is passed through is a view field.Projector definition caution zone, the caution zone covers or overlapping view field.
Fig. 3 is the process flow diagram of method of operating of the present invention.Whether step S302 utilizes detecting device 104 to detect the caution zone life entity.When detecting device 104 detects the caution zone when life entity is arranged, execution in step S304, wherein, detecting device 104 produces detection signal Input Control Elements 106.In step S306, control module 106 is controlled projector and is entered protected mode when receiving detection signal.If detecting device 104 there is no to detect in the caution zone life entity is arranged, this method will be got back to step S302 and be continued to detect the caution zone.Wherein, detecting device can be infrared ray sensor or recognition of face video camera.
In some embodiments, for example light source is under the situation of laser instrument, and above-mentioned protected mode comprises directly closes light source.In addition, (for example light source is under the situation of high-pressure sodium lamp) in other embodiments, this method further comprises provides optical attenuator component, and protected mode comprises and makes optical attenuator component block light source.
In other embodiments of the present invention, the aforesaid operations method further comprises provides loudspeaker, sends the caution sound equipment when life entity enters the caution zone in order to have detected at detecting device.
In some embodiments, the present invention more will warn the view field (as shown in Figure 2) of zone design one-tenth greater than projector.At this moment, the method for operating of projector comprises: detected life entity at detecting device and entered regional 206 o'clock of caution, made loudspeaker send the caution sound equipment; And when detecting life entity and enter view field 204, reduces by detecting device the output power of light source.At light source is under the situation of laser instrument, can directly close light source to reduce its output power.At light source is under the situation of high-pressure sodium lamp, and the available light attenuating elements blocks light source to reduce its output power.
In sum, only be the preferred embodiments of the present invention, when not limiting scope of the invention process with this, promptly all simple equivalent of doing according to claim of the present invention and description change and modify, and all belong in the scope of patent covering of the present invention.Arbitrary embodiment of the present invention in addition or claim do not need to reach whole purpose disclosed in this invention, advantage or characteristics.In addition, summary part and title only are the usefulness that is used for assisting the patent document search, are not to be used for limiting claim scope of the present invention.
