Digital home news, bought 12 bad PHILPS LED lights, fortunately, a normal light. The broken lamp head and power supply part of the decomposition of the separate, a separate power supply driver, all bright. Happy ah! Do not look at the power supply board is basically yellow, black, coke color, not to mention.

The use of 15V adjustable power supply, access to a good power supply, the voltage gradually increased, starting from the 4.5V light, 14V protection action, the input current 1.2A little change.

Measure the red - black line, 5V - 0.26A, 6v0.31a, 7v0.43a, 8v0.52a, 9v0.6a, 10v0.63a, 11v0.63a, 12v0.64a, access to the lamp holder.

There is an increase in voltage drop between the black yellow line and the current, and the 5V - 12V corresponds to 86120156192227236239239mv.

The above did not take pictures, but also a separate access to the adjustable lamp power supply, the value of the voltage is measured before the F115C value, the conclusion is: buy a good luck ah, do a simple drive can be used.
