Estimating the term…
Disclosed herein is a filament bulb with uniform luminance, which decreases the dark area at the top portion of the filament bulb and increases the luminance efficiency, and includes the following components, a bulb casing, a filament unit, a reflector ring, a driver, and a bulb cap. The bulb casing is connected with the bulb cap, and together, the two define an interior space. The driver is disposed in the bulb cap, whereas the filament unit is disposed within the interior space and the bottom of the filament unit is electrically connected with the driver. The reflector ring surrounds the exterior of the bottom of the filament unit, and is configured to reflect the light emitted from the filament unit to decrease the dark area at the top portion of the filament bulb.
A filament bulb, comprising, a bulb casing, a filament unit, a reflector ring, a driver and a bulb cap, wherein the bulb casing and the bulb cap are connected to define an interior space, the driver is disposed in the bulb cap, the filament unit is disposed in the interior space and the filament unit has a bottom that is electrically connected with the driver, and the reflector ring has an upper surface with a microstructure of bumps, wherein the reflector ring surrounds the exterior of the bottom of the filament unit and is configured to reflect the light emitted from the filament unit.
