The presentation discloses a light-emitting diode (LED) street lamp remote control system based on mobile communication, which comprises a main machine, a transfer machine and a terminating machine. A global system for mobile communication (GSM) signal receiving processing unit, a wireless signal transmitting unit and an execution unit are arranged in the main machine. A super-regeneration receiving unit, an execution unit and a wireless signal transmitting unit are arranged in the transfer machine. A super-regeneration receiving unit and an execution unit are arranged in the terminating machine. The LED street lamp remote control system based on the mobile communication achieves remote control through cell phone rings or messages, is easy to operate, low in maintaining cost and greatly convenient for management of LED street lamps. One main machine can achieve control of the street lamps of a whole street and save installing cost of the system.

The invention provides an LED street lamp with adjustable light beam radiation angle, aiming at meeting the technical requirement that the high-power LED street lamp has adjustable projecting light beam, thus leading the LED light beam to be expanded along the longitudinal direction of the road with wider amplitude, increasing the distance between every two adjacent lamps and ensuring light spots to be connected with each other; the LED street lamp consists of a two-wing aluminium mounting plate, an aluminium bracket which is provided with an aluminium type tooth piece with adjustable two-wing angle of elevation that is fixed with a lamp post, a constant-current power supply, an LED module, a lens module and a silica gel sealing gasket; when the street lamp is designed to need expend the LED light beam projecting amplitude, the positions of teeth of the aluminium type tooth piece with adjustable two-wing angle of elevation can be adjusted, so that the angle of elevation of the two-wing aluminium mounting plate can be formed, and the LED light beam projecting amplitude is increased.

A solar infrared induction garden lamp including a solar device, an infrared inductor, an LED lamp and a lamp body. After the LED lamp of the solar infrared induction garden lamp is turned on, the LED lamp is in the normal brightness when someone is in the garden, and the LED lamp is in an energy saving control with less brightness when no one is in the garden. Meanwhile, the solar device (1) supplies power to the LED lamp. Therefore, the model has the advantages of simple structure, convenient installation, safe use, strong applicability, high durability, and good energy-saving effect. The solar infrared induction garden lamp provided is mainly used on street and in rural tourism yard.

A distributed power system grouping a smart solar streetlight and a control method thereof are provided to selectively drive a system mode and an independent mode by changing a wiring configuration according to the accumulation of electricity.
CONSTITUTION: N solar streetlight blocks(20,30,40) include solar cell modules, DC-DC converters, storage batteries, LED driving circuits, and LED streetlights. A bidirectional system inverter controls the N solar streetlight blocks to be driven in a system mode and an independent mode by changing a wiring state according to the accumulation state of the N solar streetlight blocks.
