Lighting Angle Of LED String Lights

This refers to the luminous angle of the LED components on the LED light string. Generally, the general-purpose SMD LED, that is, the luminous angle of the SMD component is 120 degrees. The larger the angle of light, the better the effect of astigmatism, but relatively, the brightness of the light is correspondingly reduced. The light angle is small, the intensity of light is increased, but the range of irradiation will be reduced. Therefore, another important indicator for evaluating LED strips is the luminous angle. There are some unscrupulous manufacturers on the market, in order to increase the brightness of the light to earn higher profits, deliberately reduce the light angle, and if you are a little careless, you will buy such shoddy components.
