Projector also comprises electric quantity detection apparatus 22, first pilot lamp 23, wireless charging device 24 and the second pilot lamp 25.
Electric quantity detection apparatus 22 is connected with rechargeable battery 12 and pilot lamp respectively, and electric quantity detection apparatus 22 for the electricity of rechargeable battery 12, and when the electricity of rechargeable battery 12 is lower than predetermined value, makes the first pilot lamp 23 light.When the first pilot lamp 23 lights, rechargeable battery 12 is too low to facilitate user to know, charges in time to rechargeable battery 12.
Wireless charging device 24 is connected with rechargeable battery 12 and the second pilot lamp 25 respectively, charges to rechargeable battery 12 at wireless charging device 24, and the second pilot lamp 25 lights.Charged by wireless charging device 24, reduce charging wire, very convenient.Certainly, rechargeable battery 12 is when being full of electricity and underfill, and the second pilot lamp 25 can light different colours, facilitates user to know the situation of charging.In the present embodiment, preferably, rechargeable battery 12 can be nickel-cadmium battery, Ni-MH battery, lithium ion battery, lead accumulator and lithium iron battery etc.
Conveniently control the light intensity of light source, projector also comprises supervising device 13.Supervising device is connected with processor 14, and supervising device is used for the light intensity of acquired projections picture, and processor 14 is according to the light intensity of the monitored results adjustment light source of supervising device.
Certainly, projector can also comprise usb 15, and usb 15 can be connected with electronic equipment or storage medium, for content in electronic equipment or storage medium being projected.Here electronic equipment can be mobile phone, TV, computer, the conventional electronic product such as ipad, the carrier that storage medium can be USB flash disk, portable hard drive, SD card, SM card etc. have data storage function.Or projector comprises audio output port 16, audio output port 16 can be connected with the player such as earphone, sound equipment, for the output of sound in project content.
Projector of the present invention is applicable to being applied to connecting projection more very much, to realize different drop shadow effect, is projected as example and is described below, as shown in Figure 4, connect projecting method more and comprise connecting more:
Step S401: pre-set multiple stage projector, and multiple stage projector is connected with controller;
Under different application scenarioss, user can put the position of projector as required, concrete:
Shown in Fig. 5, ask projector 1, projector 2 ... projector N is connected with controller, and all projector are all positioned at same level, their view field's slitless connection, can join together and carry out a complete successive projection, also can project voluntarily in respective view field.
Again as shown in Figure 6,4 are all connected with controller with projector, form a projection matrix, every platform projector direct view field slitless connection, can join together and carry out a complete successive projection, also can project voluntarily in respective view field.Certainly, the mode of splicing projection is not limited to 4, can be 9,16 etc.
As shown in Figure 7,4 projector are installed on orientation, four, front, rear, left and right, all projector are all connected with controller, every platform projector direct view field slitless connection, projected picture is covered with whole room, form augmented reality drop shadow effect, user can watch the projected picture of arbitrary orientation, produces sensation on the spot in person.
Step 402: controller receives from the positional information of projector, and send project content according to the positional information of projector to the projector of correspondence;
Controller, according to the positional information of projector, sends corresponding project content, such as: in splicing projection, send left side projected picture to left side projector, sends the right projected picture to the right projector.
Step 403: multiple stage projector projects according to the project content received separately, and the projected picture generated that projects combines, and forms new one projection paint.
Certainly, carrying out projector when projecting, also can monitor projection, and carry out adjustment projector according to monitoring, to ensure the consistance of each projector picture, such as: different view field, because the brightness of its surround lighting is inconsistent, even if the projection condition of projector is identical, but may there is contrast in the effect of projected picture, concrete, method also comprises:
Step S404: the picture of the monitoring camera interval schedule time to view field that every platform projector carries is taken, and obtains monitored picture, and uploads monitored picture to controller;
Step S405: controller receives monitored picture, and whether the brightness of comparison monitored picture is consistent, if unanimously, then do not process, otherwise enter step S406;
Step S406: according to monitored picture, sends brightness regulation instruction to projector, regulates the brightness of projector, to ensure the consistance of projected picture.
Multiple stage projector has coupled together projection needs, can be the projection to projected picture, as the interface in playing or video image etc.Also projector can be carried out lamplit projection as illuminator, meanwhile, the picture that every platform projector projects can be uncorrelated picture each other, also can be the view picture projected picture of the formation of mutual slitless connection.This using method connecting application flexible more, can meet the projection needs of the different scene of different user.
In embodiments of the present invention, heat abstractor 11 is arranged between DLP miniature projector 10, make full use of the space of projector, be conducive to the miniaturization of projector; In addition, the dismountable rechargeable battery 12 of projector arrangement, facilitates user to select rechargeable battery 12 or external power source to power to projector.
The foregoing is only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize instructions of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
