Chinese special wavelength manufacturer offer 3535 size ceramic 270nm 275nm 280nm SMD uvc LED

1) water clear type

2) 3535 standard  ,3.5x3.5mm size                              

3) wavelength range:280+-5nm ,UVC light

4) work volt:4.5-6.0v 40mA

also can be 255nm,265nm,280nm 310nm.

Notes:

 Avoid any direct contact with the bare hands of DUV-LED package front. In particular, the operation of non-sealed packages DUV-LED when such imitation lumen packages and ceramic chip packaged device, do not touch the LED on the surface, so as not to damage the chip lead and gold. In addition, oil pollution bare hands, will absorb ultraviolet rays. When operating DUV-LED, please use forceps gripping DUV-LED ceramic or aluminum casing, avoiding the front of the device.
Test and application conditions: 280nm uv wavelength LED because bandwidth, doping activation energy higher to a variety of reasons, the normal working voltage general in the 5-8 V, therefore, we must pay special attention to use high quality thermal conductive rubber heat dissipation, can't exist air interface between LED heat sink and circuit board.

when light up the LED (Constant current ) advice from the current (0.1 MA) gradually began to raise to 20 MA and custom-made for LED current so does not damage easily devices.

During the test if only Constant pressure power, can as the LED labeled voltage range supply directly, must not be more than LED the highest voltage mark. But the constant pressure source can only be used as a test, not as a long-term use of the power supply .

Static Electricity and Moisture Protection: Static electricity and moisture seriously damage DUV LED. Precautions must be taken whenever handling or operating these devices: (1) Equipment and machinery handling LED chips must be properly grounded. (2) Antistatic gloves must be worn whenever handling or operating these devices. (3) LED chips shall be stored in anti-static and moisture-proof container such as antistatic bag and dry cabinet filled with nitrogen.

Soldering: When applying reflow soldering, low-temperature soldering (Max Temperature: 150℃; Max Time: 2 minutes) is recommended. If high-temperature soldering must be applied, the temperature shall be kept within 260℃ and the time shall be kept within 10 seconds. Reflow soldering shall not be done more than twice. For SMD package with optical component (such as lens), high-temperature soldering shall be avoided, otherwise it can result in lens adhesion failure.
Deep uv led 265 280 310NM wavelength have the extremely high damage ability to microorganisms ( viruses, bacteria , mold spores ect.). So compare with drugs and chemicals disinfection, ultraviolet disinfection more environmental protection, no residue no drug resistance. 280nn deep uv LED , output power of units area is 254nm mercury lamp of the hundreds of times, even thousands of times, but the total radiation power is low, and radiation density with the square of the distance falling fast, so the LED are suitable for close quick disinfection.At 100mA work conditions, 2mW 280nm ultraviolet LED in 1 CM distance, radius =1 cm area coli in 15 seconds to kill 90%, 45 seconds to kill 99.9%, for other kinds of virus bacteria killing effect also is very good.

 Safety: Deep ultraviolet LEDs emit ultraviolet light, which is potentially harmful to skin and eyes. Avoid direct or reflected exposure to UV light when LED is in operation. Always wear eye protection, gloves and protective garment during DUV LED operation. Common protective gloves, sunglasses, glasses and so on can also prevent penetration of deep ultraviolet light with wavelength shorter than 320nm.
