how much money a set of solar street light? Currently on the market of solar garden light leds are mixed, the product to the customer strongly distrust. But solar garden light is a sunrise products, is a very reliable solar lamp. Only some manufacturers do not professional, which effects the reputation of the solar garden light. If using transformed from traditional lamps and lanterns of led garden light, while the light source and driver circuit for aluminum radiator mounted on the aluminum alloy lamp shell, solved the light level of protection, but the whole light source in a sealed lamp shell, the heat generated by the lamp work unable to dissipate into the air away body, lead to light emitting diode module and driving circuit work under extremely harsh environment temperature rise sharply. With the increase of temperature, light emitting diode light attenuation and even damaged, drive also damaged because the temperature was too high. The LED heat dissipation and protection is an industrial problems. By optimizing the structure and material design, can solve the contradiction between the LED lamps and lanterns of heat dissipation and product protection. The influence of the thermal design of light emitting diode life. At present, as the output of a single light emitting diode beam is low, so we need a lot of leds is placed in a module components to achieve the required lighting. Due to the light emitting diode photoelectric conversion efficiency is only 15% ~ 20%, and the rest were converted into heat energy, so when a module is placed on a large number of light-emitting diodes (leds), will increase the difficulty of the heat treatment. Problem is that the heat will lead to raise the temperature of light emitting diode module, thus results in the decrease of light emitting diode voltage, light intensity is reduced, the wavelength of light. It will affect the efficiency of light emitting diode drive, damage the magnetic components and output capacitance of the life, reduce the reliability of the light emitting diode drive, and will seriously reduce the life of the light emitting diode, accelerate the leds light attenuation. When designing led lamp, good heat dissipation design is based on the following consideration: 1) Leds luminous efficiency, increase the current ( Power) , to reduce the light emitting diode chip junction temperature ( Tj) 。 2) High optical performance and high reliability of light-emitting diodes (leds) depends on the junction temperature (light emitting diode chip Tj) 。 Therefore, good heat dissipation design is management light-emitting diode junction temperature Tj, cooling ways mainly have three kinds: conduction, convection and radiate. Among them, the conduction and convection of greater effects on the heat dissipation of LED garden light, divergence is not important. From the point of thermal analysis, heat ( q) - Divergent power PDmdash global times; This is because when ion exchange efficiency reach standard, ultrafiltration and relative changes between ultrafiltration is relatively small.
