Abstract
The utility model discloses a light emitting diode (LED) streetlamp, which comprises a front cover, a rear cover and a plurality of light source modules, wherein the appearance of the rear cover is of a corrugated curve, the corrugated curve is provided with a plurality of heat radiation holes, and the back part of a shell of the light source modules is provided with a heat radiation plate. By adopting the above technical scheme, the lamp can effectively dissipate the heat, prevent the water and the dust and can resist the strong wind and heavy rain. Through the unique fin design of the module and the ventilation design of the shell, the heat radiation maximization can be guaranteed, the light attenuation is greatly reduced, and the service life of the LED streetlamp is adequately guaranteed. Due to the modularized product design, the LED streetlamp is easier to assemble, repair and upgrade.
Description
Technical field
The utility model relates to a kind of LED street lamp.
Background technology
The LED street lamp is the efficient solid state light emitter that the faint electric energy of a kind of usefulness of based semiconductor PN junction formation just can be luminous; Under certain forward bias voltage and injection electric current; The electronics that injects hole and the injection N district in P district is diffusing to active area after radiation recombination and send photon is converted into luminous energy with electric energy.It is a kind of solid-state cold light source, has characteristics such as environment friendly and pollution-free, little power consumption, light efficiency is high, the life-span is long, and therefore, the LED street lamp will become the optimal selection that roadway illumination and energy saving is transformed.Existing LED road lamp cooling is bad, causes led light source wherein short service life.
The utility model content
The utility model technical problem to be solved provides a kind of LED street lamp, good heat dissipation, long service life.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the LED street lamp comprises protecgulum, bonnet and some light source modules, the appearance undulate curved surface of said bonnet; This waveform curved surface is provided with some louvres, and the housing back of said light source module is provided with fin.
As preferably, the two ends of said light source module are respectively equipped with joint pin, and said protecgulum inboard is provided with the groove of spacing said joint pin.
As preferably, said joint pin is cylindric, and it is semicircle that said groove becomes, and is fixed with a semicircle fixture with this groove fit through screw on the said groove.
As preferably, said louvre is a bar hole.
The utility model is owing to adopted technique scheme, and this light fixture can effectively dispel the heat and waterproof and dustproof, can the heavy rain of anti-high wind.Fin design that module is unique and ventilation for enclosures design guarantee the heat radiation maximization, significantly reduce light decay, fully guarantee the service life of LED street lamp.Modular product design, assembling and maintenance upgrading more easily.
