    摘要: A downlight apparatus includes a light passing cover, a light source module, a surface rim and a driver plate. The surface rim has a rim part, a reflection part and a bottom part. The rim part is connected to the reflection part. The reflection part is connected to a top edge of the bottom part. The bottom part defines an installation cavity with the top edge as a cavity opening. The rim part defines a light opening. A first light of the plurality of LED modules passes through the light passing cover and a second light of the plurality of LED modules is reflected by the reflection part before passing through the light passing cover. The rim part, the reflection part and the bottom part are made of the same material as a unibody module.

    摘要: 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.

    摘要: A gas-free light bulb device has a lamp head, heatsink, a bulb, a glass core column, multiple filament assemblies, and a resilient extending element. The heatsink is mounted on the lamp head and has a mounting slot and a driver circuit board mounted in the mounting slot. The bulb is mounted on the heatsink and has a cavity. The glass core column is mounted in the mounting slot. The filament assemblies are mounted on the glass core column. The resilient extending element is mounted on the glass core and has a resilient rubber sleeve mounted around the glass core column and multiple resilient extending rubber bars connected respectively to the filament assemblies. When the gas-free light bulb device is operated with rising temperature, the resilient rubber sleeve is heated and loosened to slide upward and drive the filament assemblies to contact the bulb to effectively dissipate heat.
