The invention discloses a phase-shift processing based LED driving system. The phase-shift processing based LED driving system is characterized by comprising a transformer T, a rectification filter circuit, a phase-shift circuit, a driving circuit and an open-circuit protection circuit, wherein the rectification filter circuit is connected with a secondary side of the transformer T, the phase-shift circuit is connected with the rectification filter circuit, the driving circuit is connected with the phase-shift circuit, and the open-circuit protection circuit is connected with the driving circuit. The phase-shift circuit comprises a phase-shift chip U1, a triode VT1, a triode VT2, a resistor R2, a capacitor C2 and the like, wherein one end of the resistor R2 is connected with a VCC+ pin of the phase-shift chip U1 while the other end of the resistor R2 is connected with an IN1 pin of the phase-shift chip U1, and a cathode of the capacitor C2 is connected with the IN1 pin of the phase-shift chip U1 after passing by a resistor R1 while an anode of the capacitor C2 is connected with an IN2 pin of the phase-shift chip U1. Compared with the prior art, the phase-shift processing based LED driving system has the advantages that by the aid of the phase-shift circuit, voltage of the driving system can be more stable, and influences of LED lamp flickering on light effects are avoided.

The invention relates to the field of lighting lamps, in particular to an energy-saving and high-efficient LED light. The energy-saving and high-efficient LED light comprises an installing sleeve, a fixing loop, a light shade, an overhaul structure, a LED light, a wire distributing structure and a sealing loop. The sealing loop with a plurality of circumferential array distributions is clamped onthe installing sleeve; the installing sleeve abuts against a light shade used for dust prevention, the ring-shaped is rotatingly connected with the light shade, and the fixing loop is connected with the installing sleeve in a threaded mode; the wire distributing structure used for fixing power lines is arranged on the inner of the installing sleeve; and the light shade is connected with the installing sleeve through the overhaul structure used for an assistant overhaul. According to the energy-saving and high-efficient LED light, limit is conducted between the installing sleeve and the light shade so that power can be more evenly distributed on the light shade, meanwhile the installation and disassembly of the light shade are more convenient and fast, and limit is conducted between the installing sleeve and the light shade through the overhaul structure for the convenience of the temporary light shade fixing when a light is overhauled and maintained; and the wire distributing structureused for classifying and storing guiding lines is arranged inside the installing sleeve for the convenience of rapid installation and disassembly of the power lines when the LED light is installed and disassembled.

The invention belongs to the field of LED lamps, and in particular relates to an anti-glare type high heat dissipation LED underground lamp, comprising an outer shell and an inner shell, the inner shell is provided with an LED lamp group, the inner shell and the outer shell The upper ends are all open, the inner casing is set in an inverted circular truncated shape, and a flexible annular plate is arranged above the inner casing and the outer casing, and the inner ring and the outer ring of the flexible annular plate are respectively connected to the inner casing and the outer casing. The outer casing is fixedly connected, and the section of the flexible annular plate is arranged in an upwardly arched convex shape. A sealed cooling liquid cavity is formed between the inner casing, the outer casing and the flexible annular plate, and the cooling liquid cavity is filled with For cooling liquid, two light-transmitting plates are fixedly connected to the inner side wall of the inner casing, an opacifying agent is filled between the two light-transmitting plates, and a cooling liquid pipe is arranged between the two light-transmitting plates. The invention can lower the temperature of the sunscreen agent by stepping on the flexible annular plate by pedestrians, so as to play a light shielding effect, prevent glare from being generated, and affect the safe passage of pedestrians.

The invention discloses a multi-energy illuminating lamp. The lamp comprises a lamp body, a lampshade is fixedly connected to one side of the outer portion of the lamp body. One side of the outer partof the lampshade is fixedly connected with a dust shielding mechanism; the dust shielding mechanism comprises a connecting shaft B at the top end of the lampshade; fixing bolts B are fixedly connected to the two ends of the connecting shaft B; a dust shielding cover is fixedly connected to the surface of the top end of the connecting shaft B; a limiting rod is fixedly connected to one end of theouter surface of the dust shielding cover, a connecting shaft A is fixedly connected to one end of the limiting rod, fixing bolts A are fixedly connected to the two ends of the connecting shaft A, a fixed rod is fixedly connected to one side of the outer portion of the connecting shaft A, and the middle of the lower surface of the lamp body is fixedly connected with a supporting mechanism. By designing the dust shielding mechanism installed on the surface of the top end of the lampshade, the outer surface of the lampshade can be effectively prevented from dust, and the situation that when thelamp is not used for a long time, certain dust is accumulated outside the lampshade, and consequently the lighting effect is affected is avoided.
