Now more and more city street lamp use led as
light source, led light source has many advantages, so some parts of the energy-saving reform will also choose to use led light source, led street lamp light source to meet those conditions?
In northeast area in China, every year in October to April the following year, generally in a state of ice and snow, LED lights and outdoor LED lamps and lanterns before afternoon near evening lights, temperature may be lower than 20 degrees below zero, then evening electricity work, due to the LED lamps and lanterns to fever, may also make the lamp body temperature to rise to about 40 degree, basic every day have to undergo a high low temperature cycle impact of lamps and lanterns, under this kind of environment temperature, if the LED street lamp manufacturers of outdoor LED lights processes is not good, the LED lamps and lanterns of the structure design and material matching problem, it is easy to cause the waterproof silicone ring and waterproof material cracking and failure problems, in the case of large temperature difference, water evaporation sucked through the LED lamps and lanterns, directly cause the lamps and lanterns is the inside of the chip and the water drive power supply bubble water problems, for a long time, can produce LED lamps and lanterns is destroyed by the damage to light.
Used in cold zone of outdoor LED lamps and lanterns, also note that in addition to the LED light source of LED drive power, strong ultraviolet ray lamp body material and the fog weather factors.
Power development must pay attention to the low temperature start, pay attention to propel the internal low-temperature electrolytic capacitor activity decline, prevent capacitance decay is too big, lead to circuit doesn't work.
LED street lights manufacturer preferably wide working temperature range capacitance, high quality, of course, this increases the cost of capacitor.
To adopt no electrolytic capacitor circuit design and other good drive solutions.
In the alpine zone, north the fog into consideration, involve the light penetration problem, suggest that it is best to use the warm color temperature of 3000 k, strong penetrating power, also warmer in snow, not a piece of white.
Research and development production of transformers street lamp in low temperature and excellent waterproof performance, can rest assured choice.
More than benchmarking products in guangdong province led lights for you in the case of low temperature using the matters needing attention, hope to help you!
