Lighting device for lighting and detecting/warning presence of smoke and/or hazardous gases e.g. carbon-dioxide, has non-flammable PVC base and non-flammable PVC cover including hole at its center for installation of energy-saving bulb

摘要

The device has a non-flammable PVC base (1) and a non-flammable PVC cover (2) including a hole (4) at its center for installation of an energy-saving bulb (E27). Ventilation grates (3) are provided on a surface of the cover for absorption of any smoke and toxic gas and for ventilation of an electronic system, where the device emits a warning tone that is different for each type of gas and/or smoke. LEDs (9) are connected to a battery and activated during power failure. An RJ45connector is connected to a modem for warning the presence of toxic gas by text or electronic mail.
