With regard to taking the electric capacity of famous electric capacity brand (Taiwan is vertical grand), be example: its general-40 ℃--+105 ℃ of specification electric capacity life ensuring values are (under 105 ℃ of full-load conditions) 4000 hours.If electric capacity ripple current load value maximum uses 85% when we design:
Life-span during 65 ℃ of capacitance temperatures can only guarantee approximately 80,000 hours;
Life-span during 75 ℃ of capacitance temperatures can only guarantee approximately 40,000 hours;
Life-span during 85 ℃ of capacitance temperatures can only guarantee approximately 20,000 hours;
Life-span during 95 ℃ of capacitance temperatures can only guarantee approximately 10,000 hours;
From above reckoning: 10 ℃ of the every risings of electrochemical capacitor temperature, the life-span will reduce by half.
Therefore the operating temperature that reduces LED driving power will improve its service life greatly.
