Abstract

A bulb apparatus including a bulb, a light cap, a light source assembly and a driving component. The light cap has an inner wall and an outer wall. The outer wall is used for accessing to an external power source. The light source assembly includes a base and the multiple light source components. The base carrying the multiple light source components which form an angle with respect to a predetermined position with respect to the bulb. The bottom outer shape of the base is connected with the inner wall of the light cap. The driving component is disposed in a hole surrounded by the base. The driving component is connected to external power source through a terminal.

Claims4

Dependent claims

A method of manufacturing light apparatuses, comprising:

arranging at least two substrates on the same sheet;
a plurality of light source component regions being formed on one substrate, and the plurality of LED chips being set in each of the light source component regions, wherein there are gaps between two adjacent light source component regions, and the light source component regions of the two substrates are crossed to each other on the same sheet;
cutting the two substrates from the sheet;
bending the substrate to form a three-dimensional hollow light source assembly, the plurality of light source component regions of the substrate and a corresponding plurality of LED chips constituting a light source assembly, the gaps between the multiple light source component regions assisting air to pass through for heat dissipation;
bending the light source components toward different angles;
and
connecting the light source assembly to a power supply connector.
