 3, ambient temperature -20 ℃ ~ +40 ℃ (thermal design requirements of the lamp are doing better, LED lamp pins temperature must not exceed 60 degrees); 
 4, if the current time in the 14-20mA, 1mA each lower current, the brightness of the corresponding 4% reduction; 
 5, the power of the time in the 43-46mA is 0.12W, while the 46-53mA is 0.15W, while the 54-60mA is 0.18W; 
 6, the light sheet welding power after a good test, make sure to carefully check the electronic components are not connected to the phenomenon of tin, be sure there is no short circuit light board, if short, will definitely have LED lights for damage or serious damage to the beads , or will show up immediately, or to show up until a few days or longer, resulting in a hidden hazard, so that many users in the industry have occurred many times, this is particularly special to note! ! ! 

 Reliability of LED products have been tested this section are as follows: 
 1, welding test: 260 ± 5 ℃, soak for 10 seconds, three times, no one dead lights. 
 2, heat shock: 0 ℃ (15 秒) ~ 1005 ℃ (15 seconds), 20 cycles, there was no one dead lights. 
 3, high temperature storage: 100 ℃ 1000 hours storage environment, there was no one dead lights. 
 4, low temperature storage: -40 ℃ 1000 hours storage environment, there was no one dead lights. 
 5, temperature cycling: -40 ℃ ~ +80 ℃, 100 cycles, 200 hours, there was no one dead lights. 
 6, room temperature aging: 20mA, 7000 hours of aging at room temperature, 5% of decay, there was no one dead lights. 
 7, high temperature and humidity: 60 ℃ temperature and 90% humidity environment, save 1000 hours, there was no one dead lights. 
 8, high temperature aging: 85 ℃, 5mA drive, no one dead lights. 
 9, the low-temperature aging: -30 ℃, 20mA, 1000 hours of continuous light, there was no one dead lights. 
 10, room temperature aging: 30mA, 500 hours of aging at room temperature, there was no one dead lights. 

 Caution and requirements: 
 1 After opening the package please use the oven to be baked 8 hours and then 60 degrees to use, and in the temperature of 25 ± 3 ℃, humidity 65 ± 5 degrees environment. 
 2, after opening the package within 24 hours in the welding, the lights did not run out of bead, please keep it to re-sealed and dehumidification. 
 3, LED is the electrostatic sensitive devices, the use of all equipment, organizations need to be properly grounded electrical conductivity measures. 
 4, please use the costumes to use anti-static container, workers should wear anti-static clothing and wearing a rope of the ring and for effective electrostatic grounding. 
 5, subject to static electricity and surge damage the LED's electrical characteristics, there will be significant leakage current, or low voltage was changed, and even short circuit. 
 6, ferrochrome ferrochromium welding power should not exceed 40W, tip temperature should not exceed 280 ℃, soldering time should not exceed 3 seconds, the same time, anti-static and ferrochromium addition to static electricity. 
 7, the soldering temperature does not exceed 265 ℃, the peak soldering time not more than 3 seconds, while the reflow machine in addition to anti-static and static. 
 8, in the welding temperature back to normal, it will have to avoid any vibration or external force by the LED. 
 9, the product is suitable for reflow soldering. 
 10, LED is a single wizard continuity, polarity confirmation before installation, if installed anti-, in the applied voltage LED chip is often caused by damage or failure. 
 11, circuit design, LED and avoid relying too close to heating elements. 
 12, LED outside the applied voltage changes, can cause changes in the current index level, inappropriate design and current control is easy to cause LED failure, such as current life problems caused by excessive or burned, the current lack of brightness caused by too small. 
 13 BIN number of different LED components to be installed in the same time, make sure it can meet the relevant requirements of electrical and optical characteristics, such as the current is balanced, light color, brightness consistency.
