LED bulb with amplifying edge-emitting light structure

摘要

A LED bulb includes a transparent bulb base, a transparent bulb shell, a luminosity module, and a reflector. A bulb adapter is mounted on a lower end of the bulb base. A chamber is defined by the bulb base and the bulb shell, and a driver is mounted in the chamber. The luminosity module mounted in the chamber includes several LEDs and is electrically connected with the driver to allow the LEDs to be driven to project light towards the lower end of the bulb base. The reflector mounted in the chamber and located between the luminosity module and the bulb adapter can reflect light projected toward the lower end of the bulb base by the LEDs for generation of projected sidelight. The LED bulb can promote edge-emitting light which is amplified by downward projected light from the LEDs and rays reflected by the reflector.

主权项

1. A LED bulb comprising:
a transparent bulb base including lower and upper ends spaced from each other in a longitudinal direction of the bulb base, with a bulb adapter mounted to the lower end of the bulb base, with an opening formed in the upper end of the bulb base, with a driver mounted in the bulb base; a transparent bulb shell engaged with the upper end of the bulb base and sealing the opening of the bulb base, with the bulb shell and the bulb base together defining a chamber; a support board supported in the chamber and including an upper end face facing the bulb shell and a lower end face facing the bulb adapter; a first luminosity module disposed on the lower end face of the support board and including at least one first LED, with the first luminosity module electrically connected to the driver, allowing the at least one first LED to be driven to project light beams towards the lower end of the bulb base; and a first reflector held in the chamber and between the first luminosity module and the bulb adapter, with the first reflector spaced from at least one first LED of the first luminosity module in the longitudinal direction, with the first reflector reflecting rays projected toward the lower end of the bulb base by the at least one first LED.
