LED lamp circuit of current more conference appear what problem
LED current assembly LED life expectancy, calorific value is big, long droop decay quickly makes the current big but light from the darkness, also is actually short service life. String or depending on the design of the circuit. The string of reasonable and important. LED type belongs to the current control device, it is recommended that the concatenated as much as possible, control current. But the list of much needed voltage too much is bad for safety. When the number of string reaches the corresponding voltage should be increased and accordingly. Such as lamp had better control transformer within the safety voltage is better, after 24 v, for example, the pressure drop of about 3 v LED, and the best in a 6-7 more appropriate, the branch with current constant flow control device for the LED work, the more number of lights, and the same number again with constant current control, this is more reasonable.
Large current and more way to reduce the current. Of the main parameters affecting the service life of the LED is current and temperature, electric current, the greater the corresponding calorific value was greater, so the LED driver must reasonable control current, the other current large whole lamp of photosynthetic efficiency is low.
Will first fever, if it is too big, can burn out directly. On the issue of the lights, string, and, have a plenty of string and share
