LED's main performance parameters


   Light efficiency: The total luminous flux (lumens, brightness) emitted by the light source and the power consumed by the light source (watts) ratio, known as the light efficiency of the light, LED light effect generally refers to a certain turn-on current light emitted much , Or how much light is emitted per 1 W of power.

   Light emitting angle: LED light emitting angle is the light scattering angle, mainly by the production of diodes plus scattering agent to control.

   Maximum forward turn-on current: LED allows continuous maximum current.

   Junction temperature: The basic structure of the LED is a semiconductor PN junction, when the current flows through the LED components, PN junction temperature will rise, strictly speaking, put the temperature of the PN junction area is defined as the LED junction temperature, junction temperature Affect the life of LED.
