摘要： The present disclosure is for a LED submersible light comprising a light-emitting lampshade in thread connection with a back cover to form a closed chamber housing a circuit board, lamp beads, batteries, and a control switch. A silica gel sealing ring is disposed in a positioning groove along an inner surface of the back cover. When engaged the sealing ring expands laterally in both directions to fill up spaces between internal and external threads and the positioning groove.

摘要： The present invention discloses a light-emitting diode light string control system, which comprises: a switching unit having a power input end, a power output end, and a controlled end; the power output end is connected to the light-emitting diode light string; a control unit, and the control unit is connected to the controlled end of the switching unit; a second power generating unit, and the second power generating unit is connected to the light-emitting diode light string. According to the present invention, the light-emitting control command sent by the control unit is loaded on the power line of the light-emitting diode through a carrier wave mode to realize the driving of the brightness variation of the light-emitting diode light string, which saves costs and simplifies the control circuit of the light-emitting diode; the short-circuit protection unit detects whether the light-emitting diode is short-circuited in real time, has fast response rate to the protection of the light-emitting diode light string when it is short-circuited, fewer components are needed, the production cost is low, the circuit is simple, which is easy to implement, safe and reliable.

摘要： The present disclosure relates to a drive control system for a light-emitting diode string, comprising a control unit and a signal-generating unit. The signal-generating unit comprises a switching element with a first terminal, a second terminal and a control terminal. One end of the control unit is connected to the control terminal, and the second terminal is connected to a negative terminal of the light-emitting diode string. A voltage stabilizing circuit is connected to the negative terminal of the light-emitting diode string, wherein a positive terminal of the light-emitting diode string is connected to a power supply unit. When the control unit turns on the switching element, the power supply unit directly drives the light-emitting diode string to emit light. When the control unit turns off the switching element, the power supply unit drives the light-emitting diode string to emit light through the voltage stabilizing circuit.
