Outdoor LED lighting design should be consistent with China's latest outdoor lighting fixture
technical specifications, as well as urban road lighting design standards.
First, the working environment:
LED outdoor lighting due to the relatively poor working environment, by the wind and rain, the sun
in the ultraviolet light, day and night temperature changes, air dust, chemical gases and other
conditions, the lamp year after year by the natural aging treatment The Design should take full
account of the impact of these factors.
Second, LED lighting materials and cooling options:
Shell and radiator design as one, used to solve the problem of LED lighting heating, this way
better, generally use aluminum or aluminum alloy, copper or copper alloy, and other good thermal
conductivity of the alloy. Heat dissipation has air convection cooling, strong wind cooling and
heat pipe heat dissipation, (jet air cooling is also a heat pipe similar to the heat, but the
structure is more complex.
Choose what kind of cooling methods, the cost of lighting has a direct impact, should be considered,
and design products supporting the best program.
Shade design is also essential, the current use of transparent plexiglass, PC materials, etc., the
traditional shade is a transparent glass products, what kind of material selection shade with the
design of the product grade positioning, in general, outdoor lighting The shade is best for
traditional glass products, it is the manufacture of long life, the best choice for high-grade
lamps. The use of transparent plastic, plexiglass and other materials to do the lampshade, do
indoor lamp shade better for outdoor life is limited, because the outdoor sunshine, ultraviolet
light, dust, chemical gas, day and night temperature changes and other factors to shorten the life
of the lamp cover , Followed by pollution is not easy to clean up, so that the shade transparency reduces the impact of light output.
Third, LED chip packaging:
At present, the domestic production of LED lamps (mainly street lamps) are mostly using 1W LED
string, parallel assembly, this method thermal resistance than advanced packaging technology
products are high, not easy to create high-quality lamps. Or the use of 30W, 50W or even larger
modules assembled to achieve the required power, these LED packaging materials useful epoxy resin
package, useful silicone package.
