[Industrial applications]

 The present invention relates to an automatic opening / closing safety illuminator that detects a disconnection failure of a light bulb, and more particularly to an automatic opening / closing safety illuminator that always opens and closes.

[0002]

[Prior art and its problems]

 In general, illuminators in places such as bathrooms and showers are lit during use and blink when used, but because they open and close frequently, the open / close switch often fails. I often forget to turn off the switch, and the current situation is that I use electricity very much. At present, there is a device in the market that opens and closes the flashing light bulb by ultrasonic or infrared remote control, but the control device must always leave the aisle at the set time, and if someone is in the aisle, When standing, the remote control device cannot capture human moving signals, so it automatically blinks the light. Such a device is not applicable to bathrooms. It usually has a problem that when it is used in a bathroom or a shower, it can't capture human moving signals with infrared rays or ultrasonic waves, so it often blinks automatically when used. In view of this, the "automatic opening / closing safety illuminator that detects the failure of the light bulb" of the present invention was developed and designed.

[0003]

[Means for solving problems]

 The features of the automatic opening and closing safety illuminator for detecting the failure of the light bulb according to the present invention are:

(1) When a light bulb breaks down, the light automatically blinks with a light, and the user can know it so that it can be replaced automatically.

(2) When a person enters a bathroom or a shower, it is not necessary to come out within a set time.

(3) Since the present invention can accurately detect the entrance and exit of a person by the pyrothermal sensing device, it is automatically turned on when it is used and closed when it is not used.

(4) When used in a staircase room, there is no need for lighting for 24 hours, and the effect of complete power saving is exhibited.

(5) When used in a bathroom, there is no need to touch a switch when taking a bath, so there is no fear of electric leakage in wet hands and absolute safety is maintained.

(6) It is the safest because bright illumination is provided without turning on the switch when the user suddenly goes to a dry night at night and does not feel reluctant to sleep.

【Example】

 An embodiment of the present invention will now be described with reference to the accompanying drawings.

Referring to FIG. 1, after inputting an AC power supply (110 V or 220 V AC) 101, a transformer 102 is used to change the voltage to a set voltage, and then a bridge rectifier 103 is used to convert the AC power to DC power. The stabilizing circuit 104 provides the device of the present invention.

The detected signals are compared, and the switch circuit 108 controls ON or OFF, and the time circuit 109 controls the set time. After that, the driving circuit 110 controls the blinking of the light bulb 112. Since the bulb failure detection circuit 111 is provided in the bulb 112 and the bulb can be automatically displayed when the bulb fails, it is easy to replace the burned bulb. Referring to FIG. 2, T ₁ is a transformer, BD ₁ is a bridge rectifier, RY ₁ is a relay for controlling the light bulb LP ₁ , and IC is a voltage regulator IC, which provides a stable voltage to control the circuit.

Referring to FIG. 2, the sensing signal of the pyrothermal sensor (PUYROELECPRIC INFRARDED DETECT OR = PIR) of this embodiment is amplified by IC ₅ and IC ₄ , and IC _2B is amplified by the amplifier. , IC _2A , capacitor C ₇ , resistor R ₇ R ₈ , capacitor C ₈ , resistor R ₉ capacitor C _{9 and the} like. The signals are compared by the comparator after amplification, which includes IC _2B , IC _2C and D ₃ D ₄ . The signal in this embodiment provides point D of the pyrothermal sensor (PIR) as a reference point to IC _2B and IC _2C , provides point S to the signal, and makes point G a ground point. . The detection signal is timer-controlled by using the diode D ₂ , the resistor R ₂ and the capacitor C _4, and the length of the time is controlled by the time constant circuit R ₂ C ₄ . The transistor Q ₁ , the capacitor C ₁ , the diode D ₁ , the relay RY _1, etc. of the drive circuit of this embodiment are used for controlling the opening and closing of the lamp CP ₁ . The IC ₁ is a stable pressure control circuit. The present invention prevents the user from mistakenly thinking that the control circuit of the present invention has failed due to a lamp failure. For this reason, a lamp is provided to indicate the failure, and the user can easily recognize that the failure and replace it. It protects the LED with resistor R ₁₃ by cds exposure as well as by driving the LED with transistor Q ₂ . If the lamp fails, the relay end power will be supplied normally, and it will be rectified by the diodes D ₅ and D ₆ , filtered by the capacitor C, and then stabilized by the ED; cds to receive light. If not, the LED will be turned on automatically, and if the relay shuts off the power, the LED power will also be cut off. Therefore, it becomes possible to eliminate the mistake of warning.

[Effect of the device]

 The present invention provides an automatic opening / closing safety illuminator for detecting a failure of a light bulb, which detects a human body temperature and a movement signal by a pyrothermal sensor (PIR) and then outputs a signal by an expander. Enlarge, further confirm the accurate signal with the comparison circuit, give a command to the timer circuit with the switch circuit, calculate the time from the beginning of receiving the command of the switch circuit within the set time, and drive the circuit. To maintain the ON status, and when the command of the switch circuit is not received within the timer period, the drive circuit is made to blink the light bulb, and the light sensitive register is combined by the drive circuit to detect the failure of the light bulb. The feature is that the failure of the light bulb can be displayed.
