Problem; To provide an evacuation guidance system which is capable of safely and reliably guiding evacuees in response to the outbreak and spread of a fire.

Solution; An evacuation guidance system is configured from multiple sensor modules 20, network lines 30, guidance indicators 40, and a guidance control device 50. Each sensor module includes multiple input/output port pairs, fire detection sensors, and a data control unit. The multiple input/output port pairs are connected to input/output port pairs of other sensor modules by means of network lines, thereby configuring a mesh-like autonomous network. The data control unit: generates and outputs fire data after adding fire location data; upon receiving fire data, outputs the fire data after adding its own route flag; and stops the output of fire data when the fire data contains its own route flag. Upon identifying the location of the fire outbreak from the fire data, the guidance control device calculates optimum evacuation routes and causes the guidance indicators to turn on/off or flash.

The present disclosure relates to an emergency lighting circuit, an emergency start control method thereof and an emergency lighting system. When an emergency start condition is met, matching can be performed in a preset dimming database according to type information of load lighting equipment connected to a current emergency lighting circuit to obtain a dimming parameter value matching a power value required by the load lighting equipment, and finally, the load lighting equipment is directly controlled to start with the dimming parameter value. Through the above solution, when emergency lighting is started, there is no need to spend time in regulating power of the load lighting equipment, and a corresponding power value can be ensured when the load lighting equipment is started, which is highly reliable in emergency lighting start.

The present disclosure relates to an emergency lighting circuit, a control method thereof and an emergency lighting system. Normal lighting is monitored by detecting whether a charging management apparatus in the emergency lighting circuit has electric energy input. When the charging management apparatus has no electric energy input, emergency lighting may be started, and power transmitted to load lighting equipment is switched to an emergency battery apparatus through a power supply switching apparatus, which is processed by a boost inverter to provide appropriate electric energy for the load lighting equipment. A power detection apparatus detects an input-terminal power signal of the boost inverter, and regulates power of the load lighting equipment based on the input-terminal power signal. Operating power of the load lighting equipment is regulated based on the input-terminal power signal of the boost inverter. An input-terminal voltage of the boost inverter is a DC low voltage and easy to detect. Moreover, in the solution, high voltage and current are not required to be isolated for power detection, which effectively reduces detection costs and is highly reliable in power detection.

A light system monitors an area of interest for exposure to radiant energy provided by an operating room light head. At least one operating parameter of the light head is obtained, and based on the at least one operating parameter it is determined if the area of interest has been or will be exposed to radiant energy exceeding a prescribed threshold over a prescribed time period. Based on the determination, the system at least one of automatically adjusts an operating setting of the at least one light head or generates a warning of possible overexposure to radiant energy in the area of interest.

The invention relates to a luminaire (10) comprising illuminants (170) for generating light, and a control unit (110) for controlling the illuminants (170), and at least one further element (140), in particular an operator control element (143) or a sensor (142), for generating control information that influences the operation of the luminaire (10), wherein the control unit (110) is configured in such a way that a self-test is carried out after a supply voltage has been applied to the luminaire (10). Said self-test is carried out automatically and independently in an analysis mode of the luminaire (10), wherein the control unit (110) checks the luminaire (10) for the presence and/or the functionality of the at least one further element (140). Depending on the checking result, and the type of further unit (140) checked, the control unit (110) controls the illuminants (170) such that a temporally variable light emission (171) signals the checking result.
