1) Color temperature
Generally speaking, color temperature is not used as an evaluation indicator for LED flexible light strips, but due to different use environments, buyers have special requirements for white LEDs. If the color temperature of the light source is different, the light color is also different.
2) Brightness
Generally speaking, the luminous intensity of LED flexible light strips will vary with different colors. The unit of luminous intensity is millicandela (mcd), which is an important indicator for evaluating the brightness of LED flexible light strips. The greater the luminous intensity, the brighter the light strip. The higher the brightness requirement, the more expensive the price of the LED flexible light strip, so the price of the high-brightness LED chip is more expensive, and the higher the brightness, the more difficult it is to package the LED chip.
3) Lighting angle
The luminous angle refers to the luminous angle of the LED on the LED flexible light strip. General-purpose SMD LEDs generally have a luminous angle of 120°. The larger the luminous angle, the better the astigmatism effect of the LED flexible light strip, and the lower the brightness. The smaller the luminous angle, the greater the luminous intensity of the LED flexible light strip, and the smaller its irradiation range. Therefore, the luminous angle is one of the important indicators for evaluating LED flexible light strips.
4) Luminous flux
The luminous flux of each SMD3528LED lamp bead is 4~6lm, the luminous flux of the current high-brightness LED lamp bead is 712lm, and the luminous flux of each SMD5050LED lamp bead is 10~121m. At present, people generally use LED lamp beads with a luminous flux of 16~18m.
5) Voltage
Voltage refers to the input voltage (working voltage) of the LED flexible light strip. The commonly used voltages for LED flexible light strips are DC5V, DC5) voltage 12V, and sometimes DC24V voltage.
3. Features of LED flexible light strip
1) energy saving
The power of SMD3528LED flexible light strip is 4.8W per meter, and the power of SMD5050LED flexible light strip is 7.2W per meter. Compared with traditional lighting fixtures and decorative lamps, LED flexible light strip has lower power and better effect.
2) Easy to install. The LED flexible light strip is very easy to install and can be installed on a variety of supporting surfaces. Because the LED flexible light strip is light and thin, people can use double-sided tape to fix it. Non-professionals can also install LED flexible light strips, and people can DIY designs on them.
3) Wide range of applications
Due to its characteristics of softness, lightness, and pure color, LED flexible light strips are widely used in the decorative lighting of building outlines, steps, booths, bridges, hotels, KTVs and other places, as well as the production of advertising signs, various large-scale animations and characters. advertising design etc.
4) Low calorific value
The power of the single-wing LED lamp bead of the LED flexible light strip is very low, generally 0.06-0.5W, and the heat generation is small.
5) Long life
The normal service life of LED flexible light strips is 80,000~100,000 hours. Calculated by working 24 hours a day, its service life is not more than 10 years, which is several times the service life of traditional lamps.
5) Security
The power supply voltage of the LED flexible light strip is a safe voltage, DC12V, DC24V, so the LED flexible light strip is very safe to use and will not cause safety hazards.
7) Environmental protection
Both LED lamp beads and FPC are made of environmentally friendly materials, so the LED flexible light strip can be recycled, and its use will not cause pollution and damage to the environment.
8) Softness
The LED flexible light strip uses soft FPC as the substrate, which can be bent arbitrarily without breaking, easy to shape, and suitable for various advertising shapes.
