Embodiment
[0016] Such as figure 1 As shown, the energy-saving system of the present invention is mainly composed of a strobe tube VG, a constant current LED drive system, a trigger boost circuit and a pulse drive circuit. Among them, the constant current LED driving system includes a constant current LED driver QX, a field effect transistor Q5, an inductor L, a resistor R5, a controllable diode D3 and an LED lamp group. When connected, the gate of the field effect transistor Q5 is connected to the DRV pin of the constant current LED driver QX, its drain is connected to the VIN pin of the constant current LED driver QX through the inductance L and the resistor R5 in turn, and its source is is grounded. At the same time, the connection point of the inductor L and the resistor R5 is also directly connected to the CSN pin of the constant current LED driver QX.
[0017] The controllable diode D3 is connected in series between the drain of the field effect transistor Q5 and the VIN pin of t...

The invention discloses a constant-current pulse life float energy saving system. The constant-current pulse life float energy saving system is characterized by being mainly composed of a stroboscopic tube VG, a constant-current LED driver QX, a field-effect tube Q5, a controllable diode D3, an LED lamp set and the like, a grid electrode of the field-effect tube Q5 is connected with a DRV pin of the constant-current LED driver QX, a drain electrode of the field-effect tube Q5 is connected with a VIN pin of the constant-current LED driver QX through an inductor L and a resistor R5 in sequence, a source electrode of the field-effect tube Q5 is grounded, the controllable diode D3 is connected between the drain electrode of the field-effect tube Q5 and the VIN pin of the constant-current LED driver QX in series, and the LED lamp set is connected between the source electrode of the field-effect tube Q5 and the VIN pin of the constant-current LED driver QX in series. The constant-current LED driver is adopted as an electric energy trigger core, the circuit structure of a traditional life float energy saving lamp is thoroughly changed, the overall structure is simple, and manufacturing and maintenance are quite convenient.
Description
technical field [0001] The invention relates to the field of electronic energy saving, in particular to a constant current pulse life raft energy saving system. 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 heavier weigh...
