6. Caution

6.1 :5~30℃,60%。(15):60°C±5°C,24H

6.1 Storage condition: Before opening: the temperature is 5 ~ 30 ℃, relative humidity less than 60%. (After opening the 1W green led should be used within 15 days.)For Unused Product,Please dehumidification vacuum sealed.Dehumidifying conditions: 60 °C ± 5 °C, 24H. Effective use of the product sealed for one year

6.2 Attention:


(1)thermal paster(Thermal Conductivity 1.0-4.0MK/W) should be used when connect the 1W green high power led with normal PC lens to the radiator; two pins of leds shall be welded by thermostat soldering iron. Make sure that the welding temperature is under 350 ℃ and welding time in 3-5 Seconds; Assembly process to avoid external force on the colloid surface (such as pressure, friction or sharp metal nails, etc.), to avoid gold wire deformation or breakage and other abnormalities.Normal PC lens can't withstand high temperature , reflow soldering is not suitable for normal PC lens .

(2),200℃/5S High temperature LED lens is suitable for reflow soldering , and high-temperature lens can withstand 200℃ /5S , using low temperature solder paste ,in strict accordance with the reflow soldering welding operating standards .Specific operating refers to product use notes .

(3):TS 75℃,60℃

(3)Product normal operating temperature: TS point (negative pad) is less than 75degrees, The cooling body temperature less than 60degrees ,if exceeded our requirements for a given customer must make reliability assessment, resulting loss must be borne by the customer.

(4): Power Supply Select: This product is to be driven using a constant current source, and the output current of the power range meets the specifications of the book, for the use of a constant voltage source or other conditions, please do used result of risk assessment.

(5): SD protection is needed.

6.3 Other Instructions: (1)LED( Cl2,H2S、NH3、SOx、NOx)

If you use 1W green  led in any of the following conditions, please make sure its normal performance and reliability.*Place where is moist or has dew、cream、salt air、 corrosive gases(C1, H2S, NH3, SO2, NOX, etc.)

(2)LED  colloid surface dirt, use alcohol to clean.Can't use acetone caustic cleaning solvent to cleaning

7. Using Compatibility

7-1. The chemical composition of gas in lamps and surrounding environment of light source are essential to the life of the lamps, especially when you choose to use chemical composition, it is particularly important in lighting design. Before considering the use of any material, be sure to consult the product supplier or 1W green LED manufacturer. The more information obtained before using some material, the higher the performance of the lamp.

7-2. Many regular chemicals will release gaseous aromatic compounds (ie, aromatics), and even small amounts of these chemicals, the gases which they released also tend to cause Led discoloration or damage. The chemicals in test report Table 1 will cause damage of 1W green LED. Therefore, it is not recommended to use these chemicals in a solid state lighting system of Led or anywhere around the 1W green LED .

Common chemicals with LED compatibility issues

Chemicals removing hydrocarbon gas (such as toluene, benzene, xylene)

Methyl acetate or ethyl acetate (such as resurrection oil)

Cyanoacrylate (such as "glue")

Ethylene glycol ether and dipropylene glycol monomethyl ether (such as electronic equipment cleaner) (pLIoBoND®)

Formaldehyde or butadiene (such as pLIoBoND® adhesive)

Chlorine, including detergent and sprays with bleach

7-3. The following sheet is the list of common basic materials and commercial products in electronics and electrical equipment. Some of those materials can cause serious damage or light color shift phenomenon. The results of a risk assessment related materials are as shown in the sheet:
