Road lighting and people's production and living are closely related, with the quickening of Urbanization in China, and LED street lamp is to orient The advantages such as luminous, power consumption is low, drive characteristic is good, fast response time, shock resistance height, service life length, environmental protection by Gradually enter into the visual field of people, as the energy-conserving light source of new generation for most substituting conventional light source advantage in the world, therefore, LED roads The optimal selection that lamp will be transformed as roadway illumination and energy saving.
Radiator structure, ray structure and the power supply of street lamp have directly influenced the power supplying efficiency of street lamp.
Utility model content
The utility model purpose is to disclose a kind of power invariability, safe LED street lamp.
What the purpose of this utility model was realized in:
A kind of efficient energy-saving LED road lamp, including lamp holder and lamp stand, lamp holder include the upper lid and lamp body being fastened and connected up and down, Lamp body includes light-source chamber and power source cavity, and light-source chamber lower end, which is provided with arc Transparent lamp shade, power source cavity, is provided with power module, power supply mould Block includes em filtering circuit, input rectifying filter circuit, power conversion circuit and the output rectifier and filter being sequentially connected, Power module also includes PWM control chips and sample circuit, and the input of sample circuit connects the defeated of output rectifier and filter Go out end, the output end of sample circuit connects the feedback pin of pwm chip, and the output end connection power of pwm chip becomes Change circuit.
End is the arcuate structure raised up on the upper lid, is made up of the fin of some parallel arrangements, and adjacent two dissipate The vertical range of backing is identical, and the thickness of the corresponding fin of light-source chamber is less than the corresponding fin thickness of power source cavity, effectively drop Low lamp bracket thermal resistance, it is ensured that the heat that LED/light source is produced is distributed as early as possible.
It is provided with LED lamp bead, secondary optics non-imaging lens and aluminium reflective substrate, aluminium reflective substrate and sets in the light-source chamber There are some mounting grooves, LED lamp bead is welded in mounting groove, optics non-imaging lens is separately mounted at installation notch.
The arc Transparent lamp shade is high light transmittance toughened glass lampshade.
The lamp body is integral type fine aluminium die casting lamp body, and upper lid is to be covered on integral type super-high heat-conductive die casting aluminium, integral type knot Structure is more consolidated, and reduces the installation of scattered part, and light weight improves security.
The lamp stand is metalized lamp rod, and lamp stand is externally provided with outside zinc layers, zinc layers provided with electrostatic powder layer.
The lamp stand is double-arm lamp stand or single arm type lamp stand.
The utility model has the advantages that compared with prior art, of the present utility model relative to conventional light source road Lamp can economize on electricity more than 60%, and power consumption is 40% or so of conventional light fixture, and luminous efficiency reaches 50-200 lumens/watts, this practicality New power module can shield outside electromagnetic interference, coordinated by power conversion modules and pwm chip, make LED It is operated under firm power, secondary optics non-imaging lens and toughened glass lampshade, it is ensured that light fixture light emission rate is up to more than 85%, Light-source chamber is separated from each other with power supply box, independent radiating, makes street lamp high efficiency, long-life, the utility model is simple and reasonable, profit In popularization and application, the utility model realizes bat-wing distribution curve flux, effectively expands luminous intensity distribution region, reduces the black of road surface Dark areas.
