Do you know the assembly process of the LED street lamp?
The lead out line of the lamp cap is welded with the input end of the power supply, and the two power lead wires of the palm and the white are welded at the output end of the power supply.
Take the 3PCSLED lamp according to the position indicated on the aluminum substrate by the positive and negative poles. In the aluminum substrate one polarity tin, LED polar end and advance good solder welding end, and the other end of the LED welding in another pin LED package on aluminum substrate.Note: the requirements of the spot is full, no solder false, short-circuit phenomenon, the correct position of LED welding. Welding must be fitted with anti-static rings.
The center circle LED lamp package for thermal grease evenly coated on the aluminum substrate mark.
The visual appearance of a lamp shade, a lamp cup, no scratch, burr, crack, deformation and other undesirable phenomena. Take a set of samples for trial installation to confirm the size and location of the screw holes in the fittings. Visually check whether the circuit board and the polarity of the components are clearly defined; whether the copper foil is bulged or not; use the multimeter to test whether the circuit (aluminum substrate) has an open circuit or a short circuit. Check the LED luminous color and brightness, color temperature is consistent with the required, LED light surface scratches, whether the welding pin is bright. Load power supply parameters and actual values confirm whether consistent. 3 aluminum substrate screws, Palm / white two 6cm long power cord is appropriate?.
