Abstract
A light bulb includes a light source unit, an optical unit enclosing the light source unit, a chassis unit having an upper chassis part and a lower chassis part releasably fastened to one another a driver unit received within the chassis unit and configured to drive the light source unit, and a base unit engageable with a light bulb socket and coupled to the driver unit. The driver unit, the base unit, the light source unit, and the optical unit are configured for easy and quick independent replacement by a user of the light bulb.
Claims20
A chassis unit for use in a modular light bulb, the chassis unit comprising:
- an upper chassis part and a lower chassis part,
- the upper chassis part including a slot at an inside portion of a first end, a threaded surface at the first end, and a lip at an opposite second end, the slot configured to receive the base member and form a friction fit coupling, and the threaded surface configured to receive the threaded mouth of the optical unit,
- the lower chassis part including a groove at one end and a threaded portion at an opposite end, the groove configured to receive the lip of the upper chassis part and form a friction fit coupling to form a combination of an upper chassis part and a lower chassis part,
- wherein the chassis unit is configured to removably accommodate therein a driver unit of the modular light bulb, wherein the lower chassis part is configured to releasably fasten thereon a base unit of the modular light bulb, wherein the upper chassis part is configured to releasably fasten thereon a light source unit of the modular light bulb, and wherein the chassis unit is configured to releasably fasten thereon an optical unit of the modular light bulb.

A modular light bulb comprising:
- a light source unit having a base member;
- an optical unit configured to enclose the light source unit, and including a threaded mouth;
- a driver unit configured to be electrically connected to the light source unit;
- a base unit configured to be received in a light bulb socket and to be electrically connected to the driver unit;
- an upper chassis part including a slot at an inside portion of a first end, a threaded surface at the first end, and a lip at an opposite second end, the slot configured to receive the base member and form a friction fit coupling, and the threaded surface configured to receive the threaded mouth of the optical unit;
- and
- a lower chassis part including a groove at one end and a threaded portion at an opposite end, the groove configured to receive the lip of the upper chassis part and form a friction fit coupling to form a combination of an upper chassis part and a lower chassis part,
- wherein the driver unit is removably received within the combination of the upper chassis part and the lower chassis part, an electrical connection is formed when the base unit of the light source unit received in the slot of the upper chassis part, and the base unit is coupled to the threaded portion of the lower chassis part to form an electrical connection with the driver unit, and
- wherein the driver unit, the light source, the optical unit and the base unit provide for easy and quick independent replacement of any one of the driver unit, light source, optical unit and base unit by user of the modular light bulb.

A method of assembling a modular light bulb, the method comprising:
- inserting a driver unit into a combination of an upper chassis part and a lower chassis part having an upper chassis part and a lower chassis part, the upper chassis part including a slot at an inside portion of a first end, a threaded surface at the first end, and a lip at an opposite second end, the slot configured to receive the base member and form a friction fit coupling, and the threaded surface configured to receive the threaded mouth of the optical unit and the lower chassis part including a groove at one end and a threaded portion at an opposite end, the groove configured to receive the lip of the upper chassis part and form a friction fit coupling to form a combination of an upper chassis part and a lower chassis part;
- fastening the upper chassis part and the lower chassis part to one another;
- fastening a threaded portion of a base unit onto a threaded portion of the lower chassis part, wherein fastening the base unit onto the lower chassis part comprises establishing a releasable electrical connection between the base unit and the driver unit, the base unit being configured to be received in a light bulb socket;
- fastening a light source unit onto the upper chassis part by fitting the light source unit into a slot of the upper chassis part to form an interference fit, wherein fastening the light source unit onto the upper chassis part comprises establishing a releasable electrical connection between the driver unit and the light source unit, the driver unit being configured to drive the light source unit;
- and
- fastening a threaded mouth of an optical unit onto a threaded portion of the chassis unit, so that the optical unit encloses the light source unit,
- wherein the driver unit, the light source, the optical unit and the base unit provide for easy and quick independent replacement of any one of the driver unit, light source, optical unit and base unit by user of the modular light bulb.
