LED lamp band color temperature

Refers to a standard black body heating, temperature rise to a certain extent when the color from the dark red LED band color temperature is generally divided into warm white, white, cold white several, different races on color temperature adaptability is not the same, like Europe and the United States are more like the cold white temperature LED lamp band.

The main factor that affects the price of LED soft light belt

The material and production process used in LED soft light belt, such as LED chip used. Led Glue LED welding process and so on. The LED soft lamp belt has the characteristics of low power consumption, high brightness, long life of light source, high safety performance, beautiful appearance and so on. Fixed light source led. With a super-long life 20 to 50 times longer than traditional neon, this feature avoids the cost of replacing the product in practical application, saving not only time but also cost.

Common lamp bead type

3014,2835,5630,5050

Other lamp belt type: low-voltage lamp belt, S-type lamp belt, neon lamp

Components luminous angle: common luminous angle 120 degrees. The bigger the luminous angle, the better the astigmatism effect. But relative, its luminance also reduces correspondingly in the lamp belt.

Why strip have the resistance?

According to the conventional use of LED current to calculate resistance, resistance mainly plays the role of shunt voltage limit, LED is a current limit, can not be too high, the general voltage between 2.55-3.45, as long as the voltage is 12V-13v, the brightness will be slightly different, so that the LED terminal voltage range in a small range of fluctuations, thus ensuring LED life.
