Energy-saving lamps for marine life rafts based on pulse modulation conversion

Abstract

The invention discloses a marine life raft energy-saving lamp based on pulse wave modulation and transformation. The marine life raft energy-saving lamp based on pulse wave modulation and transformation is characterized by mainly comprising a pulse wave modulator AX, a capacitor C2, a diode D9 and other structures, wherein one end of the capacitor C2 is connected with an FB pin of the pulse wave modulator AX, the other end of the capacitor C2 is connected with a VSS pin of the pulse wave modulator AX through a diode D1, one end of the diode D9 is connected with a COM pin of the pulse wave modulator AX, and the other end of the diode D9 is connected with a VCC pin of the pulse wave modulator AX through a resistor R6. As a breakthrough, the marine life raft energy-saving lamp dramatically adopts the pulse wave modulator as an electric energy trigger core, the circuit structure of a traditional life raft energy-saving lamp is thoroughly changed, and the marine life raft energy-saving lamp is simple in whole structure and very convenient to manufacture and maintain. In addition, the energy consumption of the marine life raft energy-saving lamp can be effectively reduced, and the power consumption of the marine life raft energy-saving lamp can be only 1 / 20 of the power consumption of a traditional flashlamp.

Description

technical field [0001] The invention relates to the field of electronic energy saving, in particular to an energy-saving lamp for marine life rafts based on pulse wave modulation conversion. Background technique [0002] At present, whether it is an air crash or a sea disaster, life rafts are all indispensable life-saving equipment. And just must save as the electric energy of life raft, to ensure that the flashing warning light that is used for sending distress signal can work more persistently. In the past, life raft lights used seawater batteries to ignite two small electric beads of 3V and 0.25A, one of which was used as a distress signal, and the other was used as lighting inside the raft. However, to maintain 8 hours of lighting and emergency power, at least seawater batteries are required to have a capacity of 4Ah (Ampere hours). Due to the relatively large volume of seawater batteries and the high energy consumption of life raft lights, this not only leads to the l...
