Thyristor LED is an excellent alternative to the parts that exist today, which are used in the manufacture of lighting fixtures. Advantages of LED: long service life, low power consumption and small overall dimensions.
LED operation principle
The reason for the glow is the process of recombination of positively charged holes and negatively charged particles in the p-h-junction zone. This zone is the contact of two materials (semiconductors) with different electrical 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 value of the current strength, the diode may fail. The brightness of the LED can also be adjusted downwards. Its design is very simple, but at the same time, most manufacturers do not disclose the secret of their products.
Today, a modern thyristor LED is very productive, because its efficiency ranges from 60 to 70%. If we compare incandescent lamps (the efficiency of which is only 5-7%) with LED, then the latter are betterten times normal. The term of the declared operation of lighting devices that use a thyristor LED is ten years of continuous luminescence. Energy savings when using LED, compared to LDS, is approximately 50%, and compared to incandescent lamps - 85%.
The light output of modern diodes can compete with MGL and HPS (as well as HPS). This indicator is equal to 150 lm / W. The payback period for LED lamps is 2-3 years. Subsequently, for the remaining ten years, you save 85% of the electricity consumed each month.
LEDs. Features
LED, whose characteristics are not inferior to analogues, have the following advantages:
- glass is not used in the manufacture of LEDs, so this type of lighting lamps have high strength, vibration resistance and reliability;
- LED is resistant to voltage drops and consumes only 0.4-0.6 A;
- thyristor LED works effectively under extreme conditions, even at very low temperatures.
In order to run an LED, a rather expensive diode bridge is needed, which is why the price of lighting fixtures was previously quite high. Manufacturers have solved this problem. The electrical circuit was changed, and triac dimmers were used instead of thyristor dimmers. The result was a device consisting of two thyristors connected in parallel-opposite way. Due to this innovation, there is no need to use a diode bridge today. This decision led tocheaper products and significantly increased the safety and quality class of products based on thyristors.
Thyristor LED is widely used in lighting industry. Its long service life, reliability and practicality delight consumers, because chandeliers and other devices with LED-backlight are not only economical, but also look extraordinarily beautiful.
