Solar energy lawn lamp every 6 meters large parts should be how to choose the street lamp price
The major solar energy lawn lamp fittings should be how to choose a set of complete system of solar energy lawn lamp cover: light, controller, battery, solar energy battery components and light body. By day, solar modules convert light energy into electrical energy stored by the controller to the battery
solar energy lawn lamp' Lawn lamp design mainly exterior and downy lamplight add security for urban green space landscape and beautiful, and generally has the characteristic such as easy installation, adornment sex is strong, can be used for park, garden villas, square, greening, greening of the place such as decorative lighting. 】 Major parts should be how to choose the
a complete set of solar energy lawn lamp' Solar energy lawn lamp is a kind of green energy lamps and lanterns, safety, energy saving, environmental protection, easy installation, etc. 】 System includes: light, controller, battery, solar battery components 【 Solar energy battery components is of high efficiency crystalline silicon solar cell lines of toughened glass, super white cloth, EVA, transparent TPT backboard and the composition of aluminum alloy frame. 】 And the light body. By day, solar modules convert light energy into electrical energy stored in the storage battery by the controller, battery at night through the controller to power a light source, make it into light energy, lighting decoration. Main system protection and the day of the lamp body adornment effect, guarantee normal operation of the cycle. In this light, controller, battery is the key to lawn lamp system performance, must carries on the optimization design in the design, the reasonable configuration. The choice of light source of solar energy lawn lamp power limitation due to the components, the light source power required is small, the zero point several watts to several ranges, and more is 0. 5 w and 1 w. Solar energy lawn lamp current department using energy-saving lamp as light source, the ordinary energy-saving lamps of photosynthetic efficiency of about 40 ~ 50 lm/w, and LED lamp which lights has amounted to 90 lm/w, try chamber top has more than 120 lm/w, and under the same intensity of illumination, LED lights than ordinary fluorescent lamp can be the saving electricity was above 40%, conversion efficiency is relatively high. In addition service life, the life of the common fluorescent lamp is 3000 - 5000 h, the LED light failure reaches 70% theoretical service life of about 100000 hours, the actual service life of up to 50000 hours, more than 10 times for the common fluorescent lamp, if work 8 hours a day, a light available 6250 days, so there is no need to change often, can greatly save maintenance cost. Leds are called green lighting light source, its itself does not contain toxic and harmful substances ( Such as: mercury) , avoid the secondary pollution of fluorescent tube division overflow of mercury, LED lamp driven by constant dc current at the same time, will not happen any stroboscopic, radiation and no interference, no risk to the human body; Color rendering index [ Light source for color is called color rendering of the object, is by reference or reference light source with same color temperature ( Incandescent lamp or light) The comparison of the object color appearance. 】 In 80 above, light the color of the object more real, more rich color. Therefore, the LED is very suitable for solar energy lawn lamp system. In LED applications is the most important of the constant current and heat dissipation problem, although many have used LED solar lawn lamp, but to solve these problems is not very good. In the high power LED' High power LED refers to the light emitting diode with large rated power. 】 Applications, the heat dissipation is another key consideration, heat dissipation do bad, will cause serious droop, some serious half a year may be down to half of the originally, on the lawn lamp high-power LED is a single application, the conventional aluminum plate can meet, this aspect of the influence is not big, but also need to the test.
