The main parameters of LED flexible lamp belt. With the continuous development of the LED industry, LED lamp strips have gradually become the mainstream trend in the decoration industry. LED soft light strip is the most common led light strip. There are tm1814 led strip. LED flexible light strip has the characteristics of led light-emitting elements, pure light color, soft, no glare. It can be used as decoration or lighting. Then what are the main parameters of the LED flexible light belt?
1. Color temperature
Broadly speaking, color temperature is not used as an evaluation index of the lamp belt, but because of the different application environment, the buyer will have special requirements for white LED. If the light source color temperature is different, then the light color is different. Warm color temperature below 3300K, light color red, giving a warm feeling; neutral color temperature of 3000~6000K, people in this tone have a particularly obvious visual psychological effect, there is a refreshing feeling; the color temperature of the cold color is more than 6000K, and the light color is bluish, giving people a cool feeling. Broadly speaking, the luminous intensity of the LED flexible lamp belt will vary with the color. It is an important index to evaluate the brightness of LED flexible lamp belt. The greater the intensity of the glow, the brighter the strip. The higher the brightness requirement, the more costly the price of the LED flexible lamp strip, so the high brightness LED chip is more costly, and the higher the brightness, the more difficult the packaging of LED chip.
Three, luminous Angle
The luminous Angle refers to the luminous Angle of the LED on the LED flexible lamp. General purpose SMD LED light Angle is usually 120°. The larger the luminous Angle, the better the astigmatism effect of the LED flexible lamp band, the lower the brightness. The smaller the luminescence angle, the greater the luminescence intensity of the LED lamp belt, and the smaller the irradiation range. Therefore, the luminous angle is one of the essential indexes to evaluate the LED flexible lamp belt.
Four, light flux
The luminous flux of each SMD5050LED lamp bead is 4~16lm. Now the luminous flux of the strong-light LED lamp bead is 7~12lm, and the luminous flux of each SMD50LED lamp bead is 10~12lm. At present, people commonly use LED lamp beads with light flux of 16~18lm. Voltage refers to the input voltage (working voltage) of the LED flexible lamp belt. The common voltage of LED flexible lamp belt is DC 5V, DC 12V, and occasionally DC 24V voltage is used.
