Abstract

The invention discloses a LED lamp apparatus that has individually replaceable LEDs for easy repair and maintenance. The LED lamp apparatus comprises a lamp base, LED holders and LEDs. LEDs can be inserted into the LED holders without soldering. The LED holders provide mechanical grip and electrical contact for the LEDs. The LED lamp apparatus can be mounted onto ceiling and illuminate areas that are near and relatively far away. This is achieved by using the viewing angle of LEDs and the direction that they point. The LEDs with smaller viewing angles point to and illuminate areas further away while LEDs with larger viewing angles point to and illuminate areas nearer the LED lamp apparatus.
