Safe and energy-efficient civil air defence LED ventilation mode signal box

Abstract

A safe and energy-efficient civil air defence LED ventilation mode signal box comprises an organic glass panel with three colors of green, red and yellow. A housing is divided into three small chambers. Bottom plates of the three small chambers are respectively provided with a printed circuit board. The printed circuit boards respectively connect nine high-brightness light-emitting diodes with voltage-dividing resistors. A high-volume buzzer is arranged at the left side of the housing. RV leads are used to respectively connect the three printed circuit boards, the buzzer and a wiring terminal together. The advantages of safety, energy saving, convenient installation and concise beauty are realized.

Description

technical field [0001] The patent of the present invention relates to an electrical equipment for civil air defense underground engineering, in particular to a safe and energy-saving civil air defense LED ventilation mode signal box. Background technique [0002] At present, the civil air defense ventilation signal box commonly used in civil air defense projects has high operating voltage and high total power (the rated voltage of the bulb is AC220V, the rated power is 15W, the total number of bulbs is 6, and the total power of the signal box is greater than 90W), which consumes electricity and energy. In addition, the light bulb is easy to burn out, and the green, red, and yellow three-color plexiglass panel is relatively close to the light bulb, and it is easy to bake the green, red, and yellow three-color plexiglass panel when it is powered on for a long time, posing a safety hazard. Frequent replacement of damaged parts has brought many difficulties and inconveniences to...
