Abstract

The utility model discloses a lamp remote control device, which consists of a remote control signal emitter, a receiver, a level fluctuation trigger, a single chip microcomputer controller and a driving circuit for connecting the lamp, wherein a plurality of condensed light beams emitted from the remote control signal emitter are used as remote control signals; the receiver receives the reflected light of the condensed light beams; the condensed light beams are blocked by the movement of hands to enable the reflected light to generate strong and weak change to serve as a remote control command to control the lamp; the remote control signal emitter is prevented from being held with hands; and the lamp remote control device is convenient and simple to use.

Description

Lamp remote control device

Technical field

The utility model relates to a kind of remote control of light fixture being controlled by light wave.

Background technology

Remote control in the light fixture is to adopt the receiver of remote-control sytem of hand-held remote control reflector on light fixture to send the control of signals realizations such as infrared ray or radio to light fixture open and close and brightness regulation etc. mostly at present, and the inconvenience of this control mode maximum is exactly all need pick up remote control transmitter to operate at every turn.And for example a kind of patent No. is 201110389105.7 patented technology, a camera in the employing light fixture is made a video recording to operator's gesture and is handled the control of making light, no longer control in the use with remote control transmitter, very convenient, but because its control signal need be used camera collection, and the data processing after the signals collecting is complicated higher to processor requirement, has increased the cost of light fixture.

Summary of the invention

Rely on the hand-held remote control reflector light fixture to be controlled the inconvenience of existence for solving existing lamp remote control device, and adopt there is the high problem of cost again in the gesture control mode of handling of making a video recording, the utility model will provide a kind of and need not the hand-held remote control reflector and adopt the action of hand that light fixture is controlled, and the low lamp remote control device of the simple cost of circuit.

The technical scheme that the utility model overcomes the above problems employing is: constitute lamp remote control device by remote-control signal transmitter, receiver, level fluctuation trigger, singlechip controller and the drive circuit that is connected light fixture.Wherein, remote-control signal transmitter and receiver gather together, remote-control signal transmitter sends the convergent pencil of rays of the above different modulating frequency of two bundles, and each convergent pencil of rays is separated emission in the same direction, the reverberation of the convergent pencil of rays that remote signal receiver reception reflector sends, produce the output way identical through amplification demodulator with the convergent pencil of rays number, difference incoming level fluctuation trigger, output is connected to a plurality of inputs of singlechip controller again, sample and carry out judgment processing for each convergent pencil of rays remote signal of correspondence, the singlechip controller control output end connects drive circuit and connects lamp light source again.Usually after remote-control signal transmitter sends the modulation signal convergent pencil of rays, the convergent pencil of rays reverberation that remote signal receiver receives is constant because of brightness, output level is also stablized constant after the detection, when having only when reach the convergent pencil of rays that remote-control signal transmitter sends with hand or other object on, because reflecting surface and reflective distance change, variation has taken place a little less than the reflective light intensity, and fluctuation also takes place and changes in the signal level that remote signal receiver receives, and the level fluctuation trigger can produce an output signal.Utilize this principle, enter and shift out from a light beam with hand or other object sequencing from another Shu Guang, the convergent pencil of rays sequencing is blocked, utilization stops that the sequencing difference of two above convergents pencil of rays is used as different control commands with the number of occurrence, make every road level fluctuation trigger priority different order and number of times transmit triggering signal to singlechip controller, judge processing through singlechip controller and send corresponding light controling signal, change the light source works state by drive circuit, be used to realize the conversion and the switch lamp of multiple lamp light mode.

Because the action that the employing hand stops convergent pencil of rays as remote control command, realizes light control, has saved the hand-held remote control reflector, and is easy to use, and make the circuit reduction cost low without camera head.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the circuit block diagram that the embodiment remote control constitutes.

Fig. 2 is that remote control is applied in the LED ceiling light, adopts the action that stops two convergents pencil of rays to produce the schematic diagram of remote control command.

Embodiment

Present embodiment is a remote control that is used to control the LED ceiling light.As shown in Figure 1, remote-control signal transmitter 1 generates the modulation signal of two different frequencies respectively in the present embodiment, and launch with convergent pencil of rays L1 and L2 form with two micropower laser diodes 11, the photodiode 21 of remote signal receiver 2 receives reverberation modulation signal 2L, the resonance frequency and the detection of amplify taking out separately through signal obtain real-time level and deliver to two-way level fluctuation trigger 3 port separately, 3 two outputs of two-way level fluctuation trigger connect 4 two inputs of singlechip controller, and singlechip controller 4 connects the LED light source 6 that drive circuit 5 connects ceiling light again.Ceiling light remote control and control operation demonstration are shown in Fig. 2 schematic diagram.Photodiode 21 in two laser diodes 11 and the snoot is installed on ceiling light 7, laser diode 11 is launched remote signal convergent pencil of rays L1 and L2 towards the floor direction, upwards the remote signal reverberation 2L of reflection enters photodiode 21 snoot and is exaggerated detection and is passed to level fluctuation trigger 3 as stable reference level from the floor, but level fluctuation trigger 3 did not produce action and kept ortho states this moment.When with hand or other obstacle 8 when convergent pencil of rays L1 and L2 enter and shift out, handle or other obstacle 8 upwards the reverberation remote signal 2L power of reflection change, light enters photodiode 21 in the snoot and compares with original reference level by the signal magnitude behind the amplification demodulator change has also just taken place, and successively triggers two-way level fluctuation trigger 3 respectively to 4 two input input pulses of singlechip controller signal.Utilize the pulse signal transition information of above two input singlechip controller 4 ports to be singlechip controller 4 programmings, following formula is set: shift out through the right convergent pencil of rays L2 when entering again from left side convergent pencil of rays L1 fast with hand 8, return from the right convergent pencil of rays L2 again and enter when left side convergent pencil of rays L1 shifts out at once, be " unlatching remote control " instruction, avoided like this because of producing the remote control misoperation under the situations such as walking about of people; After entering remote state, when with hand 8 be LED lamp " light-adjusting brightening remote control " instruction when convergent pencil of rays L1 moves on to L2, when with hand 8 be LED lamp " light modulation subtracts bright remote control " instruction when convergent pencil of rays L2 moves on to L1; Each remote control command EO surpasses several seconds and promptly closes remote control automatically.Also multiple remote control command can be set in the actual product as required, also can increase the number and the corresponding signal process passage of remote-control transmitting signal pcl light beam again, increase remote control command, realize more complicated control model.
