Applications: ultrasonic vibration tranducer for inkjet printer
Vibration mechanism of inkjet printer:
Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.
Piezo ceramics components features :
1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.

The type and development history of monochromatic LED
The earliest application of the LED light source made by the principle of semiconductor PN junction light was introduced in the early 1960s. The material used at that time was GaAsP, which emits red light (λp = 650 nm). At a driving current of 20 mA, the luminous flux is only a few thousandths of a lumen, and the corresponding luminous efficiency is about 0.1 lm/W. In the mid-1970s, the elements In and N were introduced to produce green light (λp = 555 nm), yellow light (λp = 590 nm) and orange light (λp = 610 nm), and the luminous efficiency was also increased to 1 lm/W. By the early 1980s, the LED light source of GaAlAs appeared, making the red LED's luminous efficiency reach 10 lumens per watt. In the early 1990s, the development of two new materials, GaAlInP, which emits red light and yellow light, and GaInN, which emits green and blue light, have greatly improved the light efficiency of LEDs. In 2000, the former made LEDs with red, orange (λp=615nm) light efficiency of 100 lumens / watt, while the latter made LEDs in the green region (λp = 530nm) light efficiency can reach 50 lumens / watt .
