Abstract
A side emitting LED is provided, and it includes a substrate, at least one LED chip, a light transmitting package and a light reflector. The substrate includes a base, and the LED chip is mounted on the base. The light transmitting package is a half-closed form and is mounted on the substrate to hold the LED chip. The light reflector is disposed on the package and corresponds to the LED chip to alter the light direction radiated from the LED chip. Therefore, the light radiated from the LED chip is reflected by the corresponding light reflector and passes through the light transmitting package to be emitted laterally.
