A power supply module: built-in power supply, charging circuit of built-in power supply and basic power supply circuit
Projection principle: suppose the mounting height is x, the step height b, the step face width a, and the lamp radius d. Setting x < b, wherein the installation angle and the side surface of the step form alpha, and because the light is projected on the step surface to form an ellipse, the maximum area of the ellipse can be required to maximally expand the projection range of the lamp light on the step surface and ensure that the installation height and the installation angle are reasonable. First, the easy-to-obtain lower edge light of the lamp can reach a distance tan α x from the side, the upper edge light of the lamp can reach a distance tan α x +2d, and the left and right edges reach a distance d. The easily available ellipse has a major semi-axis of [ tan α x +2d-tan α x ]/2 ═ tan α d, and a minor semi-axis of length d. Thus the elliptical area s ═ pi tan α d ^ 2. Thus, only the angle of α is changed in the case of a determination of the lamp radius d. Tan α is a/2/x. The lamp light is ensured to fall in the center of the step surface of the step and cannot exceed the step surface, and because of the symmetry of the ellipse and the step surface, only the limit condition tan alpha d of one side needs to be satisfied and is smaller than xtan alpha, and d is easy to obtain and is smaller than x. Therefore, when the installation height x is equal to the radius d of the lamp, the elliptical area of the projection part of the lamp light is the largest, and the illumination just reaches the whole step surface.
The working principle of the circuit is as follows: d0, D1, D2 and D3 are key state output terminals, when a key is pressed, the data port of the response outputs high level, and the relay and the power triode can be driven by adding one-stage amplification to the ports to control the load remote switch. And emitting a part of trigger signals, then encoding by PTT2262, modulating by a 315MHz modulator, amplifying by a power amplifying circuit, and finally encoding and outputting. The receiving chip PT2272 receives the signals, so long as the 1-8 pins of the PT2262 and the PT2272 are arranged the same, the 2 nd pin of the PT2262 of the transmitter is grounded, the 3 rd pin of the transmitter is connected with the positive power supply, and other pins are suspended, so that the paired receiving can be realized as long as the 2 nd pin of the PT2272 of the receiver is grounded, the 3 rd pin of the receiver is connected with the positive power supply, and other pins are suspended. The address setting jumpers are shown, and the user can be on the PCB. The address pin is directly connected to L (low level) or H (high level), thereby realizing address setting. PT2262 and PT2272 are set to be identical. When the two address codes are completely consistent, the terminals D1-D4 corresponding to the receiver output about 4V interlocking high level control signals, and simultaneously, the VT terminal also outputs a decoding effective high level signal. The high level signal is processed by the singlechip of the central control module through the signal receiving port. The processed signal is output to the light source 2 and the power device of the projection conversion mechanism through the signal output port.

When a film viewer enters a cinema, an operator sends a light source 2 and power device starting instruction signal through a remote control module, a central control module receives the light source 2 and the power device starting instruction signal and then controls the light source 2 and the power device of an indicating spotlight to start, the power device drives a rotating wheel to rotate through a transmission shaft 6, when the rotating wheel rotates to enable a beam-concentrating light emitted by the light source 2 to pass through a second light through hole and a digital pattern insert sheet, the power device stops rotating, and the light passing through the first light through hole and the pattern insert sheet projects a seat sequence number on a step surface;
when the movie starts, an operator sends out a light source 2 intensity weakening instruction signal through the remote control module, and the central control module receives the light source 2 intensity weakening instruction signal and controls the light source 2 to weaken the light intensity;
when the film finishes, operating personnel sends 2 intensity increase of light source and power device through remote control module and opens command signal, thereby central control module receives 2 intensity increase of light source and power device and opens command signal control instruction spotlight's 2 increase light intensity of light source, central control module control power device opens simultaneously, power device passes through 6 drive wheels rotations of transmission shaft, when the runner rotates to the spotlight beam of 2 launches of light source and passes second logical unthreaded hole and safe export arrow point pattern inserted sheet, power device stall, the light that makes to see through first logical unthreaded hole and pattern inserted sheet throws out the safe export arrow point on the step.
Furthermore, through the modular design of the light-transmitting block 5, different pattern insertion pieces can be conveniently replaced, and the light-transmitting block 5 can be freely selected according to requirements.
