The 5050rgb lamp bead is a kind of LED lamp bead. The 5050 is named after the product size. RGB refers to the three primary colors of red light, green light and blue light. The main features of the 5050rgb lamp bead are: 1. Low voltage drive, environmental protection and energy saving; 2, small size, easy to install; 3, high brightness, large scattering angle, good consistency The 5050rgb lamp bead is mainly used in led flexible strips, LED hard strips, LED modules, and LED backlights. 1. All dimensions are in millimeters 2. Unless otherwise specified, all tolerances for dimensioning are ±0.10mm Electrical and optical properties (Ta = 25 ° C) 1. Overcurrent protection: The customer must use a resistor to protect it, otherwise the voltage drift will cause a large change in current (breakdown occurs). When the lamp bead is used, the current must be within the specified range to avoid excessive current and cause damage. 2. Storage 2-1. Do not open the moisture barrier bag until you are ready to use the product. Please check the bag for leaks before opening the package. Check the humidity indicator card after opening the package. 20% RH The area of ​​the mark changes from blue to pink. If there is air leakage or discoloration, please contact the manufacturer or return the manufacturer to high temperature dehumidification treatment. (High temperature dehumidification environment: 120 degrees, 6H) Do not handle it yourself. 2-2. Before opening the package, the LEDs should be stored at a temperature below 30 ° C and a humidity below 70% RH. 2-3. After unpacking, the temperature is lower than 30 ° C, the humidity is lower than 60% RH, and the sealing is completed until the welding is completed at 4H. 2-4. If the hygroscopic material (silicone gel) has subsided or the LEDs have exceeded the storage time, it needs to be baked according to the following conditions: 60 ± 5 ° C / 24 hours. 3. Reflow soldering precautions 3-1. Temperature curve of lead-free solder paste 3-2. Reflow soldering should not exceed two. 3-3. Do not add any pressure to the LEDs during heating during soldering. 3-4. After welding, the current can only be over-current after returning to below 40 °C. 4. Protective measures are taken from the side of the material with appropriate tools. The product uses a silicone package to avoid crushing the gel during application and damage the internal structure. LEDs are semiconductor-sensitive devices, and electrostatic discharge (ESD) or pulsed current (EOS) can damage LEDs. The working machine is effectively grounded and the static electricity is protected during operation, which can effectively improve product quality. SMD LED lamp beads should be protected from sulfur during production and in the environment in which the lamps are used. halogen. acid. alcohol. Alkali. Ketone oxime volatile compounds, strong oxides. Plasticizers (also known as plasticizers, dioctyl phthalate DOP or dibutyl phthalate DBP, PVC materials containing a large amount of plasticizer) and other corrosive substances are in contact.
