Mining lamp

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.

Filament bulb with uniform luminance

A lighting device includes a filament, a filament fixing element, a driving circuit, a lamp holder and a bulb shell. The filament has a long strip bottom, installed with a plurality of LED modules. The filament fixing element has a bearing surface and a heat dissipation part. The bearing surface connects to the long strip bottom of the filament. The heat dissipation part is connected to the bearing surface to dissipate the heat. The driving circuit provides a suitable current to the filament for emitting light. The lamp holder houses the drive circuit and carries the filament fixing element. The bulb shell and the lamp holder constitute an accommodating space for receiving the filament and the filament fixing element.

Lighting device

A method for installing a LED light bar into a light bulb. First, place a light module into bulb shell. The light bar module has a plurality of LED light bars and expansion structure. The expansion structure is unexpanded and disposed between the plurality of LED light bars. Each LED light bar has a certain bending property. Expending the expansion structure could make the plurality of LED light bars bent to the direction of bulb shell individually. And then, remove the expansion module and install the other components of the bulb.
