Seoul mainly launched Acriche series products at Guangzhou Guangya Exhibition, such as Z-PowerLED products, including Z1, Z2, P4, Z5II, P9, Z5 and Z6 series. Among them, Z5 combines high color rendering index (CRI=90) and compact ceramic base package, suitable for general illumination, size is 3.5×3.5×2.0mm, pure white (CCT=6300K, CRI=70), warm white (CCT=3000K, CRI=90, others according to this value), amber, red, green, and blue. The luminous fluxes are 130, 80, 42, 50, 70, and 18 lm, respectively. Z6's biggest feature is improved color mixing, high efficiency, improved white balance, size is 7 × 9 × 1.5mm, full color type (RGBW), luminous flux ratio distribution is 35, 65, 15, 65lm, working current is 350mA Suitable for architectural and decorative lighting. Z7, this series of warm white LEDs has a luminous flux of up to 600 lm, mainly for the rapidly growing Asian region of the LED general lighting industry. The Schottky Diode is another type of semiconductor diode which can be used in a variety of wave shaping, switching and rectification applications the same as any other junction diode. The main adavantage is that the forward voltage drop of a Schottky Diode is substantially less than the 0.7 volts of the conventional silicon pn-junction diode.
Schottky diodes have many useful applications from rectification, signal conditioning and switching, through to TTL and CMOS logic gates due mainly to their low power and fast switching speeds.
the Schottky Diode also known as a Schottky Barrier Diode is a solid-state semiconductor diode in which a metal electrode and an n-type semiconductor form the diodes ms-junction giving it two major advantages over traditional pn-junction diodes, a faster switching speed, and a low forward bias voltage.

The metal–to-semiconductor or ms-junction provides a much lower knee voltage of typically 0.3 to 0.4 volts compared against a value of 0.6 to 0.9 volts seen in a standard silicon base pn-junction diode for the same value of forward current.
Variations in the metal and semiconductor materials used for their construction means that silicon carbide (SiC) Schottky diodes are able to turn [ON" with with a forward voltage drop as little as 0.2 volts with the Schottky diode replacing the less used germanium diode in many applications requiring a low knee voltage.
