The utility model relates to an improvement of a lighting lamp for power failure, in particular, it is a lighting lamp which is easy to use and can play an emergency lighting function in case of power failure or fire alarm, and has early warning and anti-theft functions to avoid disasters.

In general homes, shops or buildings, small light bulbs are installed on the wall for night lighting guidance, but often due to the location of the power switch, it is impossible to turn it on in the dark (power failure or fire alarm), so it is inconvenient; Keeping the lighting on all the time is relatively more wasteful in terms of electricity consumption. Due to the various inconveniences and shortcomings derived from the above-mentioned conventional light bulbs, a kind of power failure emergency lighting A (as shown in Figure 1) has been developed, and most of them are installed arbitrarily according to the needs of buildings, homes or business places. , but this power failure emergency light A is only limited to its function when the power fails, so it still has the following disadvantages in use:

1. The power failure emergency lighting device A is installed only when buildings and homes are used for fire inspections. Therefore, the willingness to install is not high, and the lighting fixtures (bulbs, PL tubes, fluorescent tubes... etc. are all acceptable) A2 Its lighting effect is only brought into play when there is a power failure, and it is not seen to work (turn on) at ordinary times. However, the internal storage battery A1 of the power failure emergency lighting lamp A is always charged and does not perform discharge action, resulting in a high failure rate of the internal storage battery A1. 2. The power failure emergency light A is not discharged in normal times, so the user does not care about the maintenance and does not pay much attention to the equipment. When encountering a power failure or disaster, they will know that the equipment has failed, and the emergency lighting function cannot be achieved, which may easily lead to dangerous accidents. .

3. This conventional power failure emergency lighting lamp does not bring into play its own function, and it can only be used to its full potential when the power is cut off. Bring into play its maximum function when alarming, so practicality is poor.

The purpose of the utility model is to provide a power failure emergency lighting infrared human body induction and anti-theft device which can achieve prediction, early warning and anti-theft function during power failure and fire alarm.

1. The infrared human body sensing device of the utility model will act immediately when it senses that a person passes by, and the built-in NC contact relay acts to cut off the AC (alternating current) power supply. The light will automatically turn off after about 20 seconds.

2. The utility model is equipped with a cds (photosensitive resistor) that can sense the intensity of ambient light, and the sensing intensity can be selected and set. When it is selected to be bright, as long as there is a person passing by, the built-in NC contact relay (normally closed contact acts as an open), this When the power fails, the emergency lighting will function as emergency lighting when the AC is cut off, and the lighting will automatically turn off about 20 seconds after the person leaves.

3. In the utility model, when the cds (photosensitive resistor) sensing circuit is selected to be dark, the sensed ambient light needs to act only when it is dark, and does not act when the brightness is too bright. In a dark environment, when someone passes by, the function will cut off the AC power supply, and the emergency lighting will be powered on when the power fails, and the lighting will be automatically turned off after about 20 seconds after the person leaves.

4. The utility model adopts the infrared human body induction circuit, because the infrared human body sensor utilizes the human body temperature and the principle of moving action, so the circuit can sense the fire alarm. When a fire alarm occurs within the sensing range, the circuit device can also Early warning.

5. The utility model has an infrared human body induction and anti-theft device for a power failure emergency lighting lamp. As long as people pass by, it can be energized at ordinary times, and the built-in storage battery can be discharged frequently, which can prolong the service life of the storage battery, thereby reducing environmental pollution and public hazards, and can be known at ordinary times. Whether the equipment is normal, it will not be ignored like a general power failure emergency lighting equipment failure, and the tragedy will be reborn in an emergency.

6. The utility model can also be used as an anti-theft device. When a person wants to leave, he only needs to turn on the anti-theft switch (turn on), and then he will automatically enter the alert state after 30 seconds, so that after the person leaves, if someone enters, the light will be on, so that Lighting, at this time, the personnel must turn off the anti-theft switch within 30 seconds, otherwise the alarm circuit will act and produce a blocking effect. If the intruder has left, the anti-theft circuit will automatically turn off after 60 seconds and reset to the automatic alert state.

When the brightness is too bright, it will not be powered on. When people pass by in a dark environment, the mains power will be cut off, and the power failure emergency lighting will achieve the lighting effect.

Please refer to the infrared human body induction controller and the anti-theft controller on the infrared human body induction and anti-theft device shown in Fig. 4 and Fig. 5, and the following two parts are described (infrared human body induction circuit, please refer to Fig. 4):

When the sensor (IR) detects that someone is moving, the signal is sent to the second pin of the IC (integrated circuit JR-168), amplified by the internal O/P amplifier and judged by the internal detection circuit, sent to the output control circuit to the 11th pin to push the triode Q101, causing the relay to act, resulting in a power outage emergency lighting, which is illuminated due to a forced power outage. However, there is an oscillating timing circuit at the 6th and 8th pins inside the IC, which can be set by an external potentiometer VB (1MR). The output will be cut off automatically after 20 seconds on site, at this time the power failure emergency lighting will turn off due to power recovery.

When there is a cds (photosensitive resistor) on the 9th pin of the IC, it can judge the external brightness, and the user can adjust it through the potentiometer VR to choose to work in the day or night. All circuits are active, if night is selected, it will only act in the night environment. (See Figure 5 for the anti-theft circuit).

When people want to leave the scene and need anti-theft function, just turn on SW ₁ (anti-theft switch), and SW ₁ is a double-pole switch. When SW ₁ is turned on, the contact of SW _1-1 (NO) is turned on , and the SW _1-2 (NC) contact is open, and the cds control is invalid. As long as SW ₁ is turned on, it will enter the anti-theft function regardless of day or night. At this time, the TIME1 timer timing circuit (set delay alarm unit) will start Timing, personnel can leave safely within 30 seconds without touching the alarm circuit. After 30 seconds, the third pin of IC (NE555) will output voltage to RL ₂ , but at this time it is only in standby state, because the coil of RL ₂ is connected to the infrared detection circuit Point P ₁ , because Q101 belongs to the cut-off situation, therefore, RL ₂ does not act.

If a person enters, it will act immediately as described above in the infrared detection circuit, and the lighting will be automatically illuminated. At this time, the transistor Q101 (P ₁ point) is turned on, the relay RL ₂ is activated, and the contact is turned on. The RL _2-2 contact is connected to RL ₄ The contacts are connected in series to ground to form a locking circuit. At this time, IC ₂ (TIME2) delays the start of the anti-theft locking alarm unit to start timing, and an alarm function will be generated after 30 seconds. If the person has left within this time, the lighting will be turned off (Q101 cut-off) , but because RL _2-2 is locked, the anti-theft alarm will work as usual unless SW ₁ is turned off within 30 seconds of TIME2.

When the anti-theft device is turned on, IC ₃ (TIME3) delays and automatically transfers to the waiting alarm unit to start timing. After about 60 seconds, RL ₄ is turned on, and the locking circuit is automatically cut off to prevent the alarm from ringing continuously after the personnel leave, such as personnel If it is still within the detection range, the anti-theft device will continue to open and will not be released due to TIME3 action.
