A thyristor LED is an excellent alternative to the parts that exist today, which are used in the manufacture of lighting fixtures. Advantages of LED: durability during operation, low power consumption and small overall dimensions.
LED operation principle
The cause of the glow is the recombination of positively charged holes and negatively charged particles in the ph transition zone. This zone is a contact of two materials (semiconductors) with different conductivity. To create a bright glow, a multilayer LED crystal design is used. Its brightness can be increased by applying a strong voltage, but with a large current value, the diode can fail. LED brightness can be adjusted in the direction of decrease. Its design is very simple, but at the same time, most manufacturers do not disclose the secret to the production of their products.
Today, a modern thyristor LED is very productive, because its efficiency ranges from 60 to 70%. If we compare
incandescent lamps (whose efficiency is only 5–7%) with LEDs, the latter are ten times better than ordinary ones. The declared life of lighting devices that use a thyristor LED is ten years of continuous illumination. The energy savings when using LEDs are approximately 50% compared to LDS, and 85% compared to incandescent lamps.
The light output of modern diodes can compete with MGL and DNaT (as well as DNaZ). This indicator is 150 lm / W. The payback period of LED lamps is 2-3 years. Subsequently, the remaining ten years you save 85% of the electricity consumed every month.
LEDs Characteristics
LEDs, the characteristics of which are not inferior to analogues, have such advantages:
- glass is not used in the manufacture of LEDs, so this type of lighting lamp has high strength, vibration resistance and reliability;
- LEDs are resistant to voltage drops and consume only 0.4-0.6 A;
- thyristor LED works effectively in extreme conditions, even at very low temperatures.
To start the LED, you need a rather expensive diode bridge, which is why the price of lighting devices was previously quite overstated. Manufacturers have solved this problem. The electrical circuit was changed, and instead of thyristor dimmers, triacs were used. The result was a device consisting of two thyristors connected in parallel-on-the-fly way. Due to this innovation, there is no need to use a diode bridge today. This decision led to cheaper products and significantly improved the safety and quality class of goods based on thyristors.
Thyristor LED is widely used in the manufacture of lighting products. Its long service life, reliability and practicality delight consumers, because chandeliers and other devices with LED-backlighting are not only economical, but also look unusually beautiful.
