ABSTRACT:
A light emitting diode (LED) lighting device has a base, a hood, an LED module, a light gathering element and a lens. The base has a container having an inner bottom. The inner bottom comprises a parallel surface and a mounting surface being connected to the parallel surface at an included angle. The hood has a reflective inner surface and is mounted in the container of the base. The LED module is mounted on the mounting surface of the container in the base, is covered by the hood and emits light beams at various angles. The light gathering element is mounted on the LED module to reflect light beams not emitted directly to the inner surface of the hood to ensure a greater percentage of light is reflected by the reflective surface to increase brightness of the LED lighting device.
