Modular high-power LED (light emitting diode) street lamp

Abstract

The invention provides a modular high-power LED (light emitting diode) street lamp which is characterized by comprising modules, a module bracket, a connector, a module cover plate, an end plate and a rod head connector. An LED driving power room is arranged in the rod head connector. A constant-current driver and a heat dissipation hole are arranged in the LED driving power room; LED lamp beads are embedded in the modules; and the number of modules can be increased or reduced according to different requirements to reach the required power. The module main body is die-cast from aluminum alloy integrally. Through the invention, a new mould and a new LED power design are not required when the shape and power of street lamps change in practical use, and the development cost of moulds and LED street lamps is reduced so as to reduce the cost of LED street lamps. The LED street lamp becomes a modular standard product. The modular high-power LED street lamp provided by the invention has good heat dissipation effect, is convenient to maintain, replace and expand, is environment-friendly and energy-saving, and has important significance in popularization.

Description

technical field [0001] The invention relates to an LED street lamp used for road lighting, and belongs to the technical field of semiconductor lighting. Background technique [0002] Now LED street lamps are popularized and applied in a large area. The street lamp products produced by most enterprises are fixed power or fixed shape. If the power needs to be changed, it is necessary to redevelop the mold and redesign the circuit. The housing of the LED street lamp is a heat sink, so when changing the power, it is necessary to re-open the mold, and the cost of the mold is very high, and ordinary enterprises cannot afford the cost of developing a large number of molds. At the same time, the effect of this shell as a heat sink is not very ideal. In harsh environments, dust accumulates in the heat dissipation shell, resulting in heat that cannot be dissipated. LEDs work in this environment, which greatly reduces the reliability and service life of LED street lights. , Restrictin...
