1、 Bottom material: Double sided electroplated board is preferred to balance practicality and heat dissipation

Double sided electroplated board: with a copper content of 2.5, it has high thickness and toughness, strong heat dissipation function, stable conductivity, and can extend the lifespan of the light strip (especially suitable for long-term lighting scenarios).

Die cutting board: The bottom plate is thin and soft, not resistant to bending and pressure, and the device is prone to damage the lamp beads, making it often dangerous to use.

Cost effectiveness proposition: Double sided electroplated panels have slightly higher costs, but lower long-term protection costs, making them suitable for scenarios with high stability requirements (such as living rooms and bedrooms); Die cutting boards are only suitable for temporary or low-frequency application scenarios.

2、 Lamp bead equipment: color rendering index and density balance to prevent excessive parameter seeking

Color rendering index (CRI):

Conventional COB light strips have a CRI of about 80-90, meeting daily lighting needs.

If high color restoration is required (such as for art displays or commercial lighting), choose a full spectrum light strip with a CRI ≥ 97, but the price is generally 30% -50% higher.

Lamp bead density:

320 LED beads/meter: up close, there may be a grainy feeling, but the price is 20% -30% lower, suitable for scenarios with limited budget or high installation height (such as ceilings).

420 beads/meter: Good continuity of lights, suitable for close range use (such as bedside and cabinet lighting).

Cost effectiveness proposition: Select density based on usage interval, and meet the daily household use with 320 LED chips; When high light quality is required and the budget is sufficient, choose 420 LED chips.

3、 Packaging process: solid color adhesive edge planning to improve light efficiency and practicality

Transparent adhesive material:

Solid color adhesive: good durability, high curvature, soft light output, no flicker.

Defective flat adhesive material: has a large luminescent surface, low luminous efficiency, significant dew on the lamp beads, and is prone to aging and yellowing.

Surrounding process:

White border on both sides: Strong spotlight effect, increased luminous power by 15% -20%, suitable for scenes with lighting needs (such as display cabinets).

Cost effectiveness proposition: Priority should be given to selecting solid color adhesive light strips with edge technology, which have better light efficiency and lifespan, and lower long-term use costs.
