A lighting apparatus includes a light source plate, a LED module, a first wire, a second wire and a terminal housing. The light source plate has a first connector and a second connector. The LED module is mounted on a first side of the light source plate to be electrically connected to the first connector and the second connector. The first wire passes through a first passage on the light source plate from a second side of the light source plate to the first side of the light source plate to engage the first connector. The second wire passes through a second passage of the light source plate from the second side of the light source plate to the first side of the light source plate to engage the second connector. The terminal housing encloses the first wire and the second wire.

Lighting apparatus

A lighting apparatus includes a light source, a detector and a driver. The light source includes a first set of LED modules and a second set of LED modules. The first set of LED modules and the second set of LED modules emit lights with different color temperatures. The detector is used for detecting an operation pattern corresponding to one of a plurality of operation modes. The operation pattern is transmitted from an operation on a wall switch electrically connected to the lighting apparatus. The driver generates a first current to the first set of LED modules and a second current to the second set of LED modules based on the operation mode associated with the detected operation pattern. The operation mode corresponding to both a corresponding luminance level and a corresponding color temperature at the same time.

A light bulb apparatus includes a central column, a central bar, a top bracket, a bottom bracket, multiple elongated filaments and a bulb shell. The central column is made of glass material. The central column has a top part, a tubular part and a trumpet part. The top part and the trumpet part are located at two opposite ends of the tubular part. The central bar is extended from the central column upwardly. The top bracket has a limiting structure to limit a movement of the top bracket relative to the central bar. The bottom bracket is fixed to the central column. The multiple elongated filaments have bottom ends fixed to the bottom bracket and with top ends fixed to the top bracket. The bulb shell has a bottom edge fixed to the trumpet part forming a container space enclosing the bottom bracket and the multiple elongated filaments.

A light bulb apparatus has a bulb shell, LED modules, a light source plate, an inner tube and an outer cup. The light source plate has a substrate plate. The substrate plate and the inner tube are made of heat dissipation material like metal material. There is a pressing portion of a lateral side of the substrate plate pressing against an inner side of the inner tube part and there is a spacing portion of the lateral side of the substrate plate not engaging the inner side of the inner tube. The outer cup part has top part and a bottom part. The inner cup is placed inside the top part of the outer cup and pressing against the outer cup.
