Parsing the LED outdoor lighting lamps and lanterns design considerations

Outdoor LED lighting lamps and lanterns design should accord with our country promulgated the latest outdoor lighting lamps and lanterns of technical specifications, and the standard of city road lighting design.

a, work environment, LED outdoor lighting lamps and lanterns is due to the working environment is poor, the wind blowing rain the sun, the sun ultraviolet radiation, temperature difference between day and night change, the dust in the air, chemical gas conditions, such as lamps and lanterns is year after year by the nature of aging treatment. Design should fully consider the impact of these factors.

2, LED lamps and lanterns of material and the cooling way choose

enclosure and radiator design as a whole, is used to solve the problem of LED lighting lamps and lanterns of fever, this way is better, generally choose aluminum or aluminum alloy, copper or copper alloys, and good thermal conductivity of other alloys. Cooling air convection heat dissipation, wind cooling cooling and heat pipe cooling, ( Jet cooling heat dissipation is a kind of similar to the heat pipe radiator, but the structure is more complicated. )

to choose what kind of operating mode, has a direct impact on the cost of lamps and lanterns, should be considered, and select the best scheme of form a complete set of product design.

the design selection of the lampshade is also vital, currently use a transparent organic glass, PC material, such as traditional chimney is transparent glass products, whether to choose what kind of materials of chimney associated with design of the product positioning, in general, the chimney of outdoor lamps and lanterns is best is one of the traditional glass products, it is long life, make the best choice for high-grade lamps and lanterns. Use transparent material such as plastic, organic glass chimney, the chimney of indoor lamps and lanterns is good, used for outdoor life is limited, because outdoor sunlight, ultraviolet rays, dust, chemical gas chimney aging, the change in the temperature difference between day and night life cut short, and the second is the pollution is not easy to dry clean, reduce chimney transparency affect the light output.

3, LED chips encapsulation

the current domestic production of LED lamps and lanterns, Mainly lamps) Are using more than 1 w leds in series, in parallel to assemble, this method is of high thermal resistance is relatively advanced packaging technology products, it is not easy to build a high quality of lamps and lanterns. Or it is 30 w, 50 w and even larger modules assembled, to achieve the required power, these LED encapsulation materials useful epoxy resin encapsulation, useful silica gel encapsulation. Mai photoelectric think current, the LED industry is in a period of rapid development, in the global economic market, who can discover opportunities to master time. Electricity channels have save offline marketing, warehousing, personnel and a series of high cost advantages, at the same time, manufacturers have more on the electricity business channel to develop creative thinking.
