LED Bulb with Amplifying Edge-Emitting Light Structure

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.
