  Photoelectric color performance detection of LED lights The main parameters of the photoelectric color performance of LED lamps include: lamp power, power factor, luminous flux, output luminous efficiency, luminous flux maintenance rate, correlated color temperature, color rendering index, chromaticity tolerance, color coordinates, and beam of reflective cup MR16 or PAR lamp. Angle, light intensity and light intensity maintenance rate.   (1) The integrating sphere system with auxiliary lamps can quickly measure all of these photoelectric color performance parameters of the LED lamp. First place the LED light in the center of the integrating sphere, and test it with the illuminated auxiliary light when the LED is not lit. The auxiliary lamp is turned off and the LED lamp under test is turned on. After the test is stabilized, the color characteristic parameter of the lamp to be tested is obtained, and the luminous flux of the LED lamp under test is automatically calculated by ...

LED packaging principle LED package is mainly to provide a platform for LED chips, so that LED chips have better performance of light, electricity and heat. Good packaging can make LEDs have better luminous efficiency and good heat dissipation environment, and good heat dissipation environment can enhance LEDs. The service life. LED packaging technology is mainly built on five main considerations, namely optical extraction efficiency, thermal resistance, power dissipation, reliability and cost performance (Lm/$). There are many kinds of LED chip packages, and different styles of packages should be used according to the actual photoelectric characteristics. However, the common LED packages have the following five common patterns. First, the LED chip soft package, this package style is generally used in the LED display of character display, digital display, and electric display. The soft package of the LED chip is to directly bond the LED chip on the PCB printing plate, and connect the d...
