An outdoor lighting designer must consider the Outdoors LED Lamp working environment LED Outdoor Lighting Due to the more complex environment, affected by temperature, UV, humidity, rainy days, rain, dust, chemical, gas and other natural conditions the impact over time, will the LED light failure caused serious problems. Therefore be considered final, outdoor lighting design when designers should consider these factors in the external environment on the impact of LED outdoor lighting. Two outdoor LED lighting in the thermal material selection should pay attention to Shell and heat sink design for the integration, to solve the LED heat problem, in this way is better, generally used in the aluminum or aluminum alloy, copper or copper alloy, as well as good thermal conductivity of other alloys. Convection cooling with air cooling, heat and strong wind cooling heat pipe cooling, (jet refrigeration cooling is similar to a heat pipe cooling, but the structure is more complicated.) Choose what kind of cooling method, the cost of the lamps have a direct impact, should be taken into account, and select the best design products matching program. Shade The design selection is crucial, the current use of transparent plexiglass, PC materials, conventional glass shade is transparent, what the election what kind of material of the shade with the grade of products designed to locate the general, Outdoor Lighting The shade is best traditional glass, which is to create long-lived, the best choice for high-end lighting. A transparent Plastic , Plexiglass and other materials to do the shade, so Indoor Lighting The shade better for outdoor life is limited, because the outside sunlight, ultraviolet radiation, dust, chemical gases, temperature difference between day and night to make lamp aging and other factors change shortened the life expectancy followed by the liquidation of a clean contaminated difficult to reduce the impact of transparency lampshade light output. Three outdoor LED chip packaging technology Current domestic production of LED lamps (mainly street) are mostly used more than 1W of LED strings, assembled in parallel, this method thermal resistance packaging technology more advanced products of high, not easy to Zaochu high quality lamps. Or the use of 30W, 50W or more modules are assembled to achieve the required power, the LED packaging materials useful in epoxy resin, useful silicone package. Is the difference between the two: epoxy resin temperature lower, easy to aging over time. Temperature silicone encapsulation is better to use should be selected. Multi-chip package and heat sink is better overall, or multi-chip package using aluminum plates and then through the phase change materials, or to link the thermal grease with the heat sink, thermal resistance than products made LED devices assembled products thermal resistance, thermal resistance less 1-2 more conducive to heat dissipation. Lamps with LED modules, module substrate is generally copper substrate, it is connected with the external heat sink to use a good phase change material, or a good thermal grease to ensure the copper substrate was reached outside the heat radiator timely up, if handled properly is easy to heat accumulation caused by module chip temperature rise too high, affecting led chip work correctly. The author believes that: multi-chip package suitable for manufacture of general lighting, modular package ideal for space limited situations create compact led lamp (Such as car headlights the main lighting, etc.). 4, in the outdoor LED lighting design of the radiator the radiator is a key light led a component, its shape, size, heat dissipation surface area of contact should be designed to benefit, the radiator is too small, led light work temperature is too high luminous efficiency and lifetime effect, radiator too, are consumers Consumables More than expected increase in product cost and weight, make the product competitive capacity decline. Led light radiator design appropriate critical. Radiator design has the following components: 1. A clear need for cooling the power LED lights. 2. Design radiator with some of the parameters: the specific heat of metal, metal, thermal conductivity, chip resistance, thermal resistance, air resistance and so the surrounding environment.
