2. When typing with F5 spotlight, the hole spacing should be15 mm. If using 546 oval lamp, the hole spacing can be controlled between 20- 10mm, and the closer the distance, the better the effect.
3. Weld the LEDs in series to produce a positive electrode (marked as A) and a negative electrode (marked as K-). The connection of lamp feet needs soldering, or they can be screwed together before soldering.
Note: it must be soldered, because the LED feet are plated with iron and silver. Once the current passes through, it will soon rust, which will cause hidden dangers to the light box and bring a lot of trouble to the after-sales. There are many conjoined lights now, which can save a lot of time and improve production efficiency, but there are only 20 lights in each row, so welding is inevitable.
Extended data:
If the lamp in the light box is too close to the light box machine, it will be regarded as a "rib" from the outside. If it is too far away, the brightness of the light box will decrease. Generally speaking, the distance between a large light box tube and the light box surface is about 10cm. Of course, due to the different light transmittance of different brands of light-transmitting film cloth, the optimal distance between the lamp tube and the light box surface will be different. Before making, you can make a sample to test the density of the lamp.
There is a lamp tube every 20 cm, and the distance between the two lamps is no more than 25 cm. In addition, the lights are generally arranged vertically; If the height of the light box is longer than one lamp tube and shorter than two lamps, it is suggested to arrange the lamps by "dislocation method", that is, 1, 3,5 are arranged upward, and 2,4,6 are arranged downward.
