Abstract
The utility model discloses a projector, comprising a motor and a power supply. A fixing bracket which can revolve along with the motor is sheathed on a motor shaft. A PCB board provided with control components is arranged on the fixing bracket, and a line of illuminating devices are arranged on the PCB board and the arrangement of the illuminating devices is parallel to the motor shaft. A copper tube is sheathed on the motor shaft, and a carbon brush touches the copper tube to provide an anode for the power supply of the PCB board provided with control components. Metal parts of the motor provide a cathode for the PCB board through a shaft core of the motor. When in use, regulating the revolution of the motor together with programming can control the switching-on of each lamp of each period and the cut-off light spots, and the light spots are projected on various objects and then various delicate cartoons, characters and patters can be projected on walls, rocks or other objects, even the clouds in the night sky, in a range of between 0.1 meter and 500 meters. The projector can be widely applied to various propaganda advertisements, family decoration and amusement toys, etc. and the price is low.
Description
Technical field
The utility model relates to a kind of projector, refers to a kind of projector that is widely used in all kinds of exploitations, home decoration, games for play etc. especially.
Background technology
At present, the projector equipment that is used for advertisement field is less, and shortcomings such as great majority exist, and projection is fixed, projecting direction is difficult to regulate, installation complexity, can provide dynamic projection picture, advertisement projector easy to use still to belong to blank in China, and existing various commercial paper product nearly all is some simple light saltus steps, and large-scale digitron display screen price is expensive, and expensive projector applications is extremely rare especially in advertisement.
The utility model content
The utility model provides a kind of advertisement projector, it is not only cheap, and only need a few components just can scan large-area various animations, the character pattern that is equivalent to up to ten thousand LED, can be widely used in all kinds of exploitations, home decoration, games for play etc.
In order to realize the purpose of foregoing invention, the technical scheme that the utility model adopted is:
A kind of projector, it mainly comprises: motor and can be to the power supply of complete machine power supply, be with the fixed support that can rotate with motor on the motor shaft, be provided with the pcb board of control element on the described fixed support, have row's light-emitting device is set on the pcb board of control element, the distribution of described light-emitting device is arranged in parallel with motor shaft.
Be with a copper pipe on the described motor shaft, a carbon brush contacts with described copper pipe, supplies with the described positive pole that has the pcb board supply power of control element, and the metal of motor is partly supplied with the negative pole of pcb board by the axle core of motor.
Described light-emitting device is laser lamp or optically focused LED lamp.
Described laser lamp or optically focused LED lamp are 8-64.
Described projector, its described power supply is an AC power, also is provided with power transformer and regulator rectifier circuit between itself and motor.
Described power supply is a battery.
After adopting said structure, during use, this novel adjustment rotation that mainly utilizes motor, by the conducting of each period every the lamp of control that programs, by luminous point, spot projection (is utilized the persistence characteristic of human eye vision) on various objects, promptly only need a few components and very low cost just can be on the wall over 0.1～500 meter, rock or other object in addition night the sky the white clouds projection go out large-area various meticulous animation, character pattern; Compare with commonly using, this is novel to be widely used in all kinds of exploitations, home decoration, games for play etc., and cheap.

Fig. 2 is a structural representation of the present utility model;
Fig. 3 is circuit theory diagrams of the present utility model.
Embodiment
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1, 2, the utility model discloses a kind of projector, it mainly comprises: motor 1 and can be to the power supply 2 of complete machine power supply, be with the fixed support 3 that can rotate with motor on the motor shaft 11, be provided with the pcb board 31 of control element on the described fixed support 3, have row's light-emitting device 4 is set on the pcb board 31 of control element, the distribution of described light-emitting device 4 is arranged in parallel with motor shaft 11.
Be with a copper pipe 12 on the described motor shaft 11, one carbon brush 13 contacts with described copper pipe 12, supply with the described positive pole that has pcb board 31 supply powers 2 of control element, the metal part of motor 1 is supplied with the negative pole of the pcb board 31 that has control element by the axle core of motor 1.
Described light-emitting device 4 is laser lamp or optically focused LED lamp.
Described laser lamp or optically focused LED lamp are 8-64.
When its described power supply 2 was AC power, itself and 1 in motor also were provided with power transformer 21 and regulator rectifier circuit 22.
Described power supply 2 is a battery, and it can directly link to each other with motor 1.
During use, this novel adjustment rotation that mainly utilizes motor 1, by the conducting of each period every the lamp of control that programs, by luminous point, spot projection (is utilized the persistence characteristic of human eye vision) on various objects, promptly only need a few components and very low cost just can be on the wall over 0.1～500 meter, rock or other object in addition night the sky the white clouds projection go out large-area various meticulous animation, character pattern; Compare with commonly using, this is novel to be widely used in all kinds of exploitations, home decoration, games for play etc., and cheap.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, wish that appended claim comprises these distortion and variation and do not break away from spirit of the present invention.
