Product Description: First, carefully read the following instructions before use 1. Before use check whether the voltage LED lights with the voltage you need, all voltages are usually: 220V, 110V. Then expand full circle lights, power 3 to 5 minutes to see if there are quality problems. 2, LED lights can only have with a converter (rectifier bridge) is supporting the power line. 3, LED lamp beads SMD LED lights with positive and negative, to pay attention to the polarity when installing the lamp body distinction, if the polarity of the lamp body on the wires does not correspond to the lamp body is not lit, Try to change the direction. 4, do not beat with a hammer or any metal tool or attack lights, or strong stretch, bend over, as this may cause some bright lights, and even the entire burned. 5. Before construction, especially in the winter, the first few lights lit the lamp with heat again after construction. 6, LED lights with To cut, press the lights every meter intervals intermediate cut (casual cut will cause one meter off). 7, If lights installed outdoors, in front of the joint, the middle joint and tail plug, be sure to waterproof plastic coated glass, so as not to cause a short circuit and when it rains. 8, when the LED lights lit, due to the resistance may have a fever, do not close the top cover objects, in order to avoid the heat does not come out and cause scattered light with melted burned 9, LED lights can not be installed in the pool (unless otherwise stated ). Second, LED parameter 1, LED lights with soft, it can be bent 360 ° special shape; 2, the use of light with light-emitting angle> 120 °. 3, the circuit structure is simple, voltage: 220V, 110V, power supply, safe and reliable; 4, waterproof type can meet the indoor and outdoor decorative lighting needs; 5, installation, maintenance, fixed easy, 6, easy to operate, according to the requirements Press the unit cut. 7, light colors Stable / beautiful. Three, LED characteristics (1) to allow power Pm: allows you to add to the positive DC voltage across the LED and the current flowing through the maximum value of the product of it. Value, LED fever, damage. (2) The maximum forward current IFm: allows you to add the maximum forward current. Exceeding this value can damage the diodes. (3) The maximum reverse voltage VRm: the allowed maximum reverse voltage applied. More than this value, the light emitting diode may be breakdown. (4) Working environment topm: light-emitting diodes with a working temperature range. Lower or higher than this temperature range, the LED will not work, efficiency is greatly reduced. Four, LED lights with a range of applications, the quality of survival to the credibility of development decorative lighting: family, hotel, shops, bars, boats, cars and other set off lighting and backlighting; 2, luminous characters light: hotels, shops, bars, restaurants and other light word light.
