Why T5 energy-saving lamps can save energy

What is T5's biggest difference between T8 parts?

T5 distinguishes T8's largest components: T5 uses electronic rectifiers, and T8 uses inductive rectifiers.

Where is the superiority of the electronic rectifier?

1. Increased power factor

The power factor ( cos ¢ ) is an important measure of power generation utilization. The lower the cos threshold is, the higher the reactive current is, and the lower the actual power that can be supplied to the user. The common inductor rectifier has a cos value of about 0.5, and the electronic rectifier can reach 0.96. Its power utilization is almost doubled. At the same output power, the power generation capacity can be reduced by half.

2. Increased luminous efficiency

Because the electronic rectifier is a high-frequency excitation, the common inductor rectifier is 60Lm/w, and the electronic rectifier can reach 88Lm/w.

3. No flicker, no noise

Inductor Rectifier has 50HZ flicker, which affects worker's eyesight, and the electronic rectifier works under supersonic frequency (the frequency range that the human ear can hear is 20HZ--20KHZ), no noise, improves the comfort of the environment

4. Start fast

Inductor rectifiers are started with bimetals. They have sparks due to electric shock. Affected by the temperature, winter starters are not easy to jump. When the voltage is low, the industry is difficult to jump. Sometimes we see that the light is off, and that's why we go to the starter. Therefore, the fluorescent lamp flickers repeatedly, causing the lamp filament to be frequently impacted and prematurely damaged.

The electronic rectifier is a high-frequency high-voltage gas glow discharge, even at -25 °C low temperature, low voltage 120V can also make the lamp ignite

5. Power saving effect is remarkable

Inductor rectifier of a 40W fluorescent lamp, due to its own core and coil, iron loss and copper loss account for 20% of the total power, its power can reach 8-9W, and the electronic rectifier itself consumes only 1-2W, plus the fluorescent material Improvement of luminous efficiency at high frequencies

So T5 is more energy-efficient than T8.
