LED   the bags after opening, as you are finished using the storage temperature is 5 ℃ -30 ℃, relative humidity below 60%. Clean Do not use unknown chemical liquid cleaning LED  flood light 50w  resin surface that may damage or even cause colloid cracks, if necessary, at room temperature led to immersion in alcohol or fluoride wrapped Aung cleaning, the time within one minute. Forming Donot forming during welding or after welding, if necessary, shaping must be completed prior to welding. Remember that any behavior of extruded resin are likely to damage LED  flood light 10w  inside the golden thread. Welding Otherwise led internal cracks in the welding process, do not exert any external pressure on the lamp body, it will affect the internal gold wire lead to quality problems. Colloid must not be immersed in solder. Welding, the welding point along the gap of at least 2 mm from the gel, the welding is completed, it is necessary to use three minutes of the time LED   30w from the high temperature back to room temperature. Such as linear array on the same pcb LED  50w  , not welded with a soldering iron, welding the same led the two pin. Soldering requires less than 30w soldering iron. led by welding the two specifications, specific parameters are as follows: Soldering temperature: 295 ± 5 ° C Soldering time: 3 seconds or less (only once) Wave soldering soldering temperature: 235 ° C ± 5 ° C Soldering time: 3 seconds or less Description: improper soldering temperature or time control may cause the LED  100w  lens deformation or wick internal open dead lights.
