The difference between energy-saving lamps and led lamps

Energy-saving lamps and LED lamps have different lighting principles The main luminescent material of energy-saving lamps is still tungsten wire. LED is the abbreviation for light emitting diode. The main component of the LED lamp is a semiconductor that can convert electrical energy into light energy. It is connected to the circuit board with silver or gold wires. At the same time, the surrounding users are sealed with epoxy resin, and the above-mentioned whole is placed in a protective shell. . Energy-saving lamps and LED lamps are different in service life, environmental protection and energy saving, and stability.

Why is the led lamp burned out?

If it is connected directly, there is no current limiting resistor. Almost all battery voltage drops fall on the LED lights. The actual voltage and current exceed the rated voltage and rated current. The LED lights have been in overload work, accelerating the aging process, and the life of the LED lights is quickly abused by the button battery to so much a little bit.

How long is the life of LED lights? Why does it feel getting darker?

The decay of luminous flux over time is a characteristic of LEDs. The current standard for the life of LEDs is mainly L70, that is, when the luminous flux decays to 70% of the initial value, it is considered to be invalid. The period of use is the life. The life of mainstream LED lamps and lamps is roughly between 15000h-50000h, which is generally marked on the outer packaging. In addition, there is also the L50 standard and the more stringent L90 standard.
