The original old how long pole to shoot the light to LED lights
LED Chinese as the light diode semiconductor has positive and negative May be you take input power + - backwards and thermal conductive glue stick to a high power LED lamp bead need radiator panels mountain or you will burn out
The assembly Electronic transformer is fixed on the original position of lamps and lanterns, two output connecting line respectively with that of the original lamp socket is linked together, good insulation and voltage polarity on the socket, and then do the LED board according to the polarity insert inside the lamp holder, even a good power cord. Check the wiring and correct after insert the 220 v power source, the light, each with 10 v voltage measurement resistance pressure drop, use the formula I = U/R calculated through the current of each group of LED lights, as long as no more than 20 ma.

Transform the power The lamp is with electronic transformer is 220 V / 50 hz ac DianZhuan into 12 V high frequency alternating current (ac) for the use of shoot the light, for the LED power supply. Now should be high frequency ac DianZhuan into 12 V dc 12 V, so that power can be multiple groups of three series of LED lights (in terms of each only 3.5 V), each lamp visible need more groups in parallel, in order to reach a certain brightness. To add a high-frequency electronic transformer rectifier filter circuit, it can be high frequency ac DianZhuan into 12 v dc 12 v. Rectifier with high-frequency rectifier tube, HFC L can use energy-saving lamps of the circular on the glass with plastic envelope around 10 turns the substitution. Cut a small piece of PCB on the above components on the electronic transformer, after connected with insulated wires - and into electronic transformer molded case, output leads to +, - two power supply line.
