What are the benefits of using 2835 lamp beads for LED tube?
Led tubes use a large number of 2835 lamp beads. Under normal circumstances, the luminous efficiency is greatly improved, which can achieve higher luminous efficiency and higher cost performance. The number of led fluorescent tube lamp beads is reduced on the original basis, but the light efficiency has increased instead, the reliability has also increased, and the processing efficiency has been improved.
2835 lamp bead led fluorescent lighting effect 2835 single lamp bead generally adopts 0.2W 22-24LM, the chip size is 10*30nm, this lamp bead is suitable for LED fluorescent lamp. The advantages are analyzed as follows:
1. 2835 lamp bead packaging structure: the chip directly conducts the heat sink, which further improves the heat dissipation performance of the lamp bead itself, so that it can withstand larger current (40-60mA), the brightness is also higher, and the excellent heat dissipation performance design is also correct. The light decay and life of LED chips are more guaranteed;
2. Ultra-thin structure: The thickness of 2835 is also 0.8mm, which can solve the spot problem of 3528; super large light-emitting surface: can increase the light output rate: up to 90%.
3. Luminous flux: Take 18Wled fluorescent lamp as an example:
If you choose to use the 2835 with 0.2W 22-24LM, the 18W fluorescent lamp needs 96 lamp beads, and the brightness of the whole lamp is about 1800LM. The 18w luminous efficiency reaches 100lm/W, entering the ranks of high-end LED fluorescent lamps. This is the standard LED fluorescent tube.
Low-end cheap price led fluorescent tubes, the lamp beads are low in brightness, and small chips are used to make them. The 18w luminous flux is 1200-1400lm, the price is cheaper. The illuminance is greatly reduced, and it does not meet the national illuminance requirements, which greatly harms the user's eyes and causes a rapid decline in vision.
It is recommended to use high-efficiency lamps as much as possible when choosing led fluorescent tubes, which has the highest cost performance.
