• Descriptions:

1. The High Powe Purple LED series is available in soft red, orange, yellow, green, blue and white. Due to the package design, the LED has wide viewing angle and optimized light coupling by inter reflector. This feature makes the SMT LED ideal for light pipe application.
2. This package LEDs are designed for high current operation and high flux output application. But the package’s design features better thermal management characteristics than other LED solutions.

• Applications:

1. Counterfeit bill detection.
2. Sterilization.
3. Medical instrument.
4. Industrial use.
5. Photo catalyst excitation.
6. Phosphor excitation.
7. Sensor.
8. QA equipment

  Paeters	Symbol	Min.	Typ.	Max.	Unit	Test Condition
  Luminous Intensity *	IV	300	350	---	mW/Sr	IF=350mA (Note 1)
  Viewing Angle *	2θ1/2	---	120	---	Deg	IF=350mA (Note 2)
  Peak Emission Wavelength	λp	---	395	---	nm	IF=350mA
  Dominant Wavelength	λd	---	405	---	nm	IF=350mA (Note 3)
  Spectral Line Half-Width	△λ	---	20	---	nm	IF=350mA
  Forward Voltage	VF	3.00	3.20	3.80	V	IF=350mA
  Reverse Current	IR	---	---	10	µA	VR=5V

  Notes:

  1. Luminous (Radiant) Intensity Measurement allowance is ± 10%.

  2. θ_1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.

  3. The dominant wavelength (λp) is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.

Ultraviolet light is mainly in the wavelength of 200-400nm (nano) light, this light people generally do not see
UV is divided into three different long wave 320-400 nm, medium wave 280-320nm, shortwave 200-280nm

Long wave now mainly used in the following areas: detection of fluorescent substances, biopolymerization, penetrating function of human skin, resulting in tanning the skin, the skin will be red for a long time; sunlight through the atmosphere filtered ultraviolet light, most of the long-wave ultraviolet Light.

UVB: poor penetration, medical, the skin surface irradiation, can treat skin diseases, this is not recommended for personal use; the sun through the atmosphere after filtering a small amount of UVA.

Shortwave UV: generally used for sterilization, he can effectively kill bacteria and parvovirus, long-term exposure to kill human cells, carcinogenic and pathological changes, so people should pay attention to prevention; UV rays of sunlight generally through the atmosphere after the filter is not Contains short-wave UV light.
