Embodiment Construction

[0009] see figure 1 As shown, a power-failure start-up lighting device capable of regular self-inspection of the present invention includes a multivibrator, a drive circuit connected to the multivibrator, a start-up self-check relay and an alarm circuit connected to the drive circuit, and a start-up self-test relay connected to the drive circuit. Check the basic circuit of the fire emergency light between the relay and the alarm circuit. Among them, the commercial power is connected to the basic circuit of the fire emergency light through the power supply and the self-test relay. When the multivibrator outputs a high level, the self-test starts, and the drive circuit drives the self-test relay contact to open, simulating a power failure; at the same time, the drive circuit also drives the alarm circuit during the self-test period, when the basic circuit of the fire emergency light outputs a low level Make an alarm. The low level output of the basic circuit of the fire emerge...

Abstract

The invention discloses an illuminating apparatus capable of starting self-check regularly during power cut, which comprises a multivibrator type oscillator, a driving circuit, a relay for starting the self-check, a warning circuit, and a fire-fighting emergency lamp basic circuit, wherein the driving circuit is connected with the multivibrator type oscillator, the relay for starting the self-check and the warning circuit are connected with the driving circuit, and the fire-fighting emergency lamp basic circuit is connected between the relay for starting the self-check and the warning circuit. By simulating the power cut and performing self-check regularly, the illuminating apparatus capable of starting self-check regularly during power cut judges whether an emergency lamp can play a role in illuminating or not during the power cut, prejudges whether the emergency lamp loses effectiveness or is damaged or not, and avoids the unnecessary loss caused by the power cut.

Description

【Technical field】 [0001] The invention relates to the technical field of emergency lighting, in particular to a power-failure start-up lighting device capable of regular self-inspection. 【Background technique】 [0002] At present, fire emergency lights for emergency lighting are widely used in various public places. Chinese Patent No. 200420120794.7 discloses an energy-saving fire emergency light for corridors, including an intermediate relay J, a DC power supply U, a capacitor C and a light-emitting diode LED. A normally open contact JK1 of the intermediate relay J is provided between the relay J and the positive pole of the DC power supply. In normal use, the coil of the intermediate relay is charged, the normally open contact JK1 is closed, and the normally closed contact JK2 is disconnected. The transformed and rectified commercial power is used to charge the DC power supply and supply power to the light-emitting diodes at the same time; when the commercial power is disc...
