Supra Skytop III Shoes
LED lights is the light-emitting diode 2 ,
Supra Skytop II Shoes, a single voltage of 3.2V,
Women's Supra Skytop II, current of 20mA. Vehicle voltage 12 ~ 14V, in order to defend the use of LED lighting extravaganza and stretched service life, constantly have to multiplication resistors to control present stream through LED lights .
current = voltage / resistance.
so a string of LED lights can be a 600 ohm resistor ,
Women's Supra TK Society, two LED light string 300 ohm resistors , 3 LED light string 200 ohm resistors ...............
components: 10CM * 20CM price board at 6 , LED light ( straw hat pate) 0.5 yuan every , the resistance of 200 ohms, 300 ohms ... .. (0.25W cost of a 0.1 yuan, according to LED lights their another number of sequence , the resistance of different sizes,
Kids' Supra Skytop Shoes, calculated in advance ) refer to the diagram , the principle is the secondary educate to increase physical resistance designed to assure namely current through the LED lights 20mA, LED lights as conservation of Role, to ensure long service life.
reading light under the door trim board space ,
Supra TK Society Shoes, and polished smooth edges . According to the length and width of circuit board design and installation of the number of LED lights , two LED light string to do a 300 ohm resistor Row 7 , the parallel circuit as
reading under the door Cutting embark chamber lights , and lustered smooth edges . According to the length and length of circumference embark chart and installation of the number of LED lights , two LED light string to do a 300 ohm resistor Row 7 , the collateral ,
soldering : namely the length of the foot LED lights Contact resistance related LED lights short thighs , and then mow off the excess thread.
welding : is the LED light resistance associated with feet together a short foot LED lights , and then cut off the excess thread.
find light, with a family recorder , video machines and other rectifiers, size 6 ~ 12V are obtainable , the power to discern results.
