Classification Of LED Tube Lights

1. Tube lights can be divided into 2-inch, 2.5-inch, 3-inch, 4-inch, 5-inch, 6-inch, 8-inch, and 10 inch sizes according to their size. Generally, there are three parameters that are related to size: outer diameter, hole size, and thickness. That is to say, the size of the holes dug during ceiling construction
2. According to the classification of lamp beads used in tube lamps, they can be divided into three types: high-power lamp beads, low-power lamp beads, and integrated lamp beads. Among them, high-power lamp beads can be further divided into 1W, 2W, and 3W single beads. Good suppliers' chips and packaging can enable lamp beads to achieve 5W and 10W power respectively; Small power can be divided into packaging forms such as 301435285050, etc; Integrated LED beads, also known as COB. In terms of appearance and heat dissipation, theoretically, low-power LED chips have less light spots and relatively good heat dissipation, which is increasingly favored by customers.
3. Generally, tube lights are equipped with fog masks, but fog masks come at the cost of reducing light efficiency. Therefore, some tube lights are also made with transparent masks
Introduction to LED Packaging Technology
1. Expand the crystal by opening the densely arranged chips to facilitate solidification.
2. Solid crystal, place conductive/non-conductive adhesive on the bottom of the bracket (whether it is conductive or not depends on whether the chip is a top bottom PN junction or a left-right PN junction), and then place the chip into the bracket.
3. Short baking to prevent the chip from moving when the adhesive solidifies and the wire is soldered.
4. Solder wire, use gold wire to connect the chip and the bracket.
5. Pre test, preliminary test to see if it can light up.
6. Apply glue to wrap the chip and bracket together.
7. Bake for a long time to solidify the glue.
8. Post test, test whether it can light up and whether the electrical parameters meet the standards.
9. Spectral separation, separating products with colors and voltages that are roughly consistent.
10. Packaging.
