ABSTRACT:
A light emitting diode (LED) unit is provided with an LED chip having a light emitting surface; and a transparent body enclosing the LED chip. The transparent body has a reflection surface that is arranged to face the light emitting surface to reflect a light beam emitted by the LED chip, and a light emerging surface that is a surface opposite to the reflection surface. The light beam emitted from the light emitting surface of the LED chip is reflected by the reflection surface, and then emerged from the light emerging surface. At least one of the reflection surface and the light emerging surface is formed to have a positive power so that a converging light beam is emerged from the light emerging surface
