Life raft energy-saving system based on constant-current protection

Abstract

The invention discloses a light beam exciting type logic protective constant-current pulse life raft energy-saving system which is mainly composed of a stroboscopic tube VG, a constant current LED driver QX, a trigger booster circuit, a pulse driving circuit and a field-effect tube Q5, wherein the pulse driving circuit is connected with the trigger booster circuit and the stroboscopic tube VG, the grid electrode of the field-effect tube Q5 is connected with a DRV pin of the constant current LED driver QX, the drain electrode of the field-effect tube Q5 is connected with a VIN pin of the constant current LED driver QX sequentially through an inductor L and a resistor R5, and the source electrode of the field-effect tube Q5 is grounded. The light beam exciting type logic protective constant-current pulse life raft energy-saving system is characterized in that a light beam exciting type logic amplifying circuit is further connected between the trigger booster circuit and the VIN pin of the constant current LED driver QX in series, and a logic protective emitter-coupled amplifying circuit is further connected between the trigger booster circuit and the pulse driving circuit in series. According to the light beam exciting type logic protective constant-current pulse life raft energy-saving system, the constant current LED driver is adopted as an electric energy trigger kernel, the circuit structure of a traditional life raft energy-saving lamp is changed thoroughly, the overall structure is simple and the light beam exciting type logic protective constant-current pulse life raft energy-saving system is quite convenient to manufacture and maintain.

Description

technical field [0001] The invention relates to the field of electronic energy saving, in particular to a life raft energy saving system based on constant current protection. 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 larger volume and...
