There are also manufacturers devoted to the development of straw hat LED with low light failure, but as the packaging form has not changed, the light failure still has not been greatly improved. This kind of LED energy-saving lamp is a transitional product with low price and poor quality. Two, by 3528 or 5050 small and medium power LED energy-saving lamps, the power supply is also commonly used in the resistor-capacitance voltage step down circuit.

White, blue, green voltage is between 3.0-3.6V, here I want to remind is that the same batch of production of LED voltage will also have some differences, according to the manufacturer to provide the standard, in the outside temperature rise, VF will decline. (Negative temperature coefficient characteristics of LED). LED reverse voltage VRm: Maximum reverse voltage allowed to increase. Beyond the value, the LED may be broken down and damaged. LED color temperature: to the absolute temperature K, that is, a standard black body heating, when the temperature rises to a certain degree, the color begins to change from dark red - light red - orange yellow - white - blue.
