Traffic lights should be avoided in dark and humid areas during normal use to extend battery life. If the battery and circuit of the signal lamp are stored in a cool and damp place for a long time, it is easy to damage the electronic components.So in our daily maintenance of traffic lights, should pay attention to its protection, in the waterproof test, what is we need to pay attention to it?
The water spray test device of the traffic signal lamp is used for waterproof test. The radius of the semicircular tube should be as small as possible, corresponding to the size and position of the LED signal lamp, and the water jet hole on the tube should allow water to be sprayed directly into the center of the circle.
The water pressure at the entrance of the device is about 80kPa. The tube should swing 120, 60 on either side of the vertical line. The full swing time (23120) is about 4 seconds. Luminous traffic lights should be installed above the rotating shaft of the pipe so that both ends of the luminaire.
Turn on the power supply of the LED signal lamp, so that the LED signal lamp is in normal working state, the lamp rotates around its vertical axis at the speed of 1r/min, and then spray water to the signal lamp with water spray device, 10 minutes later, turn off the power supply of the LED signal lamp, so that the lamp is naturally cold, continue to spray water for 10 minutes. After the test, the sample is inspected visually and dielectric strength is tested.
Traffic signal light has been widely used because of its corrosion resistance, rain resistance, dustproof, impact resistance, aging resistance, long service life, high absorption and circuit stability characteristics. Generally used to warn and remind drivers to drive carefully to avoid traffic accidents and accidents.
Put traffic lights in a place with enough sunlight to store energy to keep it recycled. When not in use, charge it every 3 months to avoid damaging the battery. When charging, you need to turn off the switch first to extend the battery life. Keep the lamp stable when using, avoid falling from the height, so as not to damage the internal circuit.
