LIGHT-EMITTING DIODE COMPONENT HAVING A LIGHT DIRECTION-CHANGING UNIT AND RELATED LIGHT DIRECTION-CHANGING UNIT AND MODULE

摘要

A light-emitting diode (LED) component includes a circuit board, an LED chip installed on the circuit board for emitting light, and a light direction-changing unit. The LED chip is composed of a plurality of light-emitting points. The unit has a covering surface covering the LED chip, and a reflecting surface having a plurality of reflecting points. A smallest included angle of a plurality of included angles between a normal line of at least one of the reflecting points and a plurality of connection lines passing through the reflecting point and the light-emitting points is larger than sin-1(1/n), where n is the reflection index of the light direction-changing unit.
