Application scope of LED light strip

The led strip refers to the assembly of LEDs on a strip-shaped FPC (flexible circuit board) or PCB hard board. It is named after the shape of the product is like a strip. Because of its long service life (normally 80,000 to 100,000 hours), and very energy-saving and environmentally friendly, it has gradually emerged in various decoration industries.

There are two common types of LED strip structures: one is a common type, the other is a series-parallel circuit structure; the other is a series-parallel circuit structure. The other is the combination type, which is the structure used by the magic light strip, which contains integrated circuits and timing control circuits.

The application range of LED light strips is very wide. As follows:

1. Home decoration (stair lighting, corridor lighting, lighting decoration, trimming decoration)

2. Path description and exterior wall decoration, billboard backlight, advertising signs, channel signal signs, etc.;

3. Buildings, pavilions, bridges, park squares and other contour lines, architectural lighting decoration, various indoor and outdoor lighting projects;

4. Festival decoration, event venue layout, exhibition venue decoration, exhibition hall decoration, display cabinets, shop windows, props and other application decorative lighting;

5. Car chassis decoration, good brake indicator, body decoration, interior decoration.

Both LED strips and multi-channel LED applications require a constant voltage input, typically 60V. Typically used for primary lighting, each LED string or channel requires an LED driver IC. Typically, linear LED driver ICs are suitable for LED currents up to 250mA, while switch-mode LED driver ICs are suitable for higher LED driver currents. Applications using linear LED driver ICs require ICs with low voltage overhead so that as many LEDs as possible can be connected in series. As a result, LED boards can improve efficiency and reduce thermal overload - two characteristics that are required by the market.

Multi-channel LEDs are ideal if a combination of high brightness output and low output voltage (ie below 60V) is required. For such high-current applications using switch-mode LED drivers, the key challenges are current accuracy, PWM and analog dimming performance, and thermal protection.
