Description of the invention: [Technical field to which the invention pertains] A remote control transmitter that emits a remote control signal, which uses a battery as a power source and uses light such as infrared rays as a transmission medium. [Prior Art] Including the control transmitter 1, a product as shown in Fig. 12 is provided, ίί is a light-emitting portion 13 of the body (10) 12, and the (10) system ===== remote control Wei. Moreover, the remote control transmitter 1 is used by the integrated body to control the communication time for the communication. The output terminal of the remote-controlled transmitting fishing rod battery bt includes a transistor Qiu 1st unit, and the xenon signal LED 12 is connected in series and the transistor Tr1 is switched by the control unit 19 § 'Vc. Thereby, the battery BT is turned to the light-emitting portion. ^ Voltage output switching switch, and the remote control signal is emitted from the communication LED 12 by the method ra Φ 12, the light-emitting portion 13 is provided with a plurality of (three) communication LEDs 12, and the i-terminal resistance R5 is connected in series and each In the case where the communication LED 12 is connected to the battery BT, as the battery is depleted, the output voltage of the battery 」 "the resistance of the battery 提高 is gradually increased. As shown in Fig. 13(a), the remote control transmitter 1 is lowered, and as the battery pack is worn, the voltage applied to the light-emitting portion 13 of the battery pack is also lowered. Therefore, the flow to the light-emitting portion 13 By = as shown in FIG. 13(b), decreases as time passes. In other words, the minimum current (Fig. 13(b) 2th) of the battery BT } is more than that of Fig. 13 (b). The current of the battery τ portion flows to the light-emitting portion 13', so that the power consumption becomes large and accelerates. The auxiliary surface has proposed a structure in which the current of the battery BT flows to the light-emitting portion 13 of the light-emitting portion 13 is lowered by the capacitor 11' connected in parallel with the battery BT, even if the internal resistance of the battery BT rises, and the capacitor is removed from the auxiliary capacitor. Current is supplied to the portion 13, and a current required to blink the communication LED 12 can be flown to the light-emitting portion 13. However, in such a configuration, in the auxiliary capacitor, there is a case where a leakage current flows between the electrodes due to a dielectric, and power consumption is generated and the phase loss of the battery is accelerated. In particular, when a large-capacity auxiliary capacitor is used, the leakage is large, and the loss of the battery BT is accelerated and the battery life is shortened.

H iff ί can be kept at approximately 4 values, but this base current value is controlled according to the way of 邰19. Therefore, the base current cannot be set to the optimum value, and because the current period is required to blink 2 Since the minimum current is larger in the current light portion 13, the power consumption is increased, the loss of the battery BT is accelerated, and the battery life is shortened. The present invention is constructed in view of the upper case, and the object thereof is to provide a remote control transmitter. Extends battery life compared to conventional structures. Hand 1 | The invention of 1 includes: a light-emitting diode for communication, which is generated by a power supply, and a remote control that emits light as a transmission medium is formed by an integrated circuit. The communication uses the timing of the first-extremely swaying, so that the remote control signal is emitted from the communication light-emitting 1345888-pole body, and the transistor 'collector-emitter is connected in series with the communication light-emitting diode- Between the output terminals of the battery; the regulator takes the output dust of the battery as an input, outputs a constant voltage 'and supplies power to the control unit; and the drive circuit responds to the control signal from the control unit by flowing to the transistor The base current is switched to delete the light-emitting diode for communication. The feature is that the circuit has a component, a control til is received from the control unit, and a switch is switched; and a pair of voltage divider resistors are connected in series with the component. Connected to the output of the regulator. Moreover, a pair of voltage-dividing resistor contacts are connected to the base of the transistor, and when the switching element _N] is used, the base current of a threshold is flowed through the crystal. Constant current flows to Tonghu Lake According to this structure, since the connection voltage is connected in series with the switching element and connected to the output of the regulator, the voltage divider resistor is connected to the junction of the resistor and the junction of the resistor, j J = crystal Ϊ base When the voltage is applied to the switching element, it becomes a constant voltage after the regulating resistor is divided. As a result, the electro-mechanical electric current of the transistor becomes a constant current flowing to the communication light-emitting diode. The base current value of the body is determined by the resistance value of the voltage dividing resistor. Therefore, the base current can be set to the optimum value by the resistance value of the Lang voltage dividing resistor, and the light can be transmitted. The minimum current flows into the communication structure' to extend battery life. In addition, if the fiber resistance can be set first, the current is more stable than the current flowing to the voltage divider resistor, and the base current is more stable. The invention of Jiaqing Special Wai 2 is in the scope of patent application! The generator container is connected between the output terminals of the regulator for leveling and adjusting, and the output voltage of the I-period is used to level the capacitor, and the base current value of the transistor is more ambiguous, and It can flow to the light-emitting diode for communication.

According to this structure, since the power supply of the control unit is leveled by the output capacitor of the regulator, The source is stable. And @@ is the second off unit, which also prevents the occurrence of leakage current of the device. Therefore, it can suppress the power consumption caused by the leakage current, and the battery life is 345888, and even because of Since the second switching unit is shared by both the leveling capacitor and the auxiliary capacitor, a simple circuit configuration can be formed as compared with the case where two second switching units are provided.

Remote transmitter! The integrated circuit (in this case, a microcomputer) includes a control unit that rotates a control signal Vc for controlling the timing of the communication LED 12 a =. Further, the control unit 19 causes the communication signal 2 to blink by responding to the control signal Vc. The remote control signal is transmitted from the communication LED. The control unit 19 is connected to the sensing device 2' by the detecting human sensor Sa and the brightness sensor Sb, and the brightness sensing setting unit 6 and the brightness sensing setting unit 7. The control unit generates the control signal vc according to the output of the sensing shake 2. In the following description, the patterns of the human sensor Sa, the brightness sensor Sb, the operation stay time setting unit 6, and the brightness sensing setting unit 7 are omitted. Here, an ηρη-type transistor Tr' is provided between the output ends of the battery BT and the light-emitting portion 13 is connected in series with the light-emitting portion 13; and the drive circuit 2A is controlled by the control signal Vc' from the control portion 9 The base current switching switch that flows to the transistor Tr1, 12 flashes at 5888·12; 俾 通讯 通讯 通讯 通讯 通讯 通讯 以 以 以 以 发射 发射 发射 发射 发射 发射 发射 发射 发射 发射 发射 电池 电池 电池 发射 发射 发射 发射 发射 发射 发射 发射Here, the battery BT is two single 4H. As for the ugly communication, the anode is connected to the battery unit 3^). The emitter of the electric body Tr 1 is connected to the negative electrode of the battery BT via a resistor R1. i The area used by Thunder ϊ , is the active area that is slightly proportional to the magnitude of the base current; and 'If the base current is fixed, the remote control transmitter 1 of the electric test, mm·4' contains the adjustment 1121. (3 terminal regulator) 'By connecting the input terminal Ti_ ground terminal between the output terminals of the battery bt, the output of the BT is used as the input mosquito (4) (in this case m; and Otani (such as ιοοπ) The leveling capacitor C1 is connected to the input port of the regulator 21) (again; the sub-unit Τ 2 ° Γ = terminal Tg) for leveling the output of the regulator 21 to the output control unit 19, and controlling The part w acts by adjusting the source of the ίmf.

Further, the switching element Qi uses a ====== big paste, and the ship-divided piezoelectric becomes 13 1345888. Therefore, when the switching element Q1 is (10), a certain value of the base current • the transistor TH can be supplied, and thereby, a constant current can be supplied to the communication LED 12 of the light-emitting portion 13. Further, since the base current value of the transistor Tr1 is determined by the voltage dividing resistor 贬 and their resistance values, the base current can be set to an optimum value by adjusting the resistance values of the voltage dividing resistors R2 and R3. Further, by minimizing the current required to pass through the light-emitting portion 〖3, it is possible to suppress the power consumption and to increase the battery life.

Thereby, when the base current flows, there is almost no change in the voltage dividing resistor, and the base g current is more stabilized by suppressing the variation of the base of the transistor Tr1. For example, in order to flow a total of 800 mA of current to the communication LED 12 of the light-emitting unit 丨3, and set the base current of the transistor Tr1 to 1 mA, the resistance values of the voltage resistors R2 and R3 are set to 100 Ω, and the transistor is The TH ^ beauty flow is sufficiently smaller than the current flowing to the voltage dividing resistor R3. earth

A flat capacitor ^ α. The remote control transmitter 1 of the present embodiment is different from the remote control transmitter i of the embodiment in that the drive circuit 20 is omitted, and the transistor Tr1 is directly switched off by the signal Vc from the control unit. Among them, the transistor is used as the first switching unit in the saturation region, and the magnitude of the collector current does not change even if the control signal 变动 varies. Further, the regulator 21 of the first embodiment and the leveling capacitor C1 are used as the control unit 19 for giving the lightning pressure to the battery BT.
