Abstract

A lamp bulb having a core column and a plurality of internally stretching miniature lamp beads therein, wherein the lamp bulb has on one end thereof a metallic cap. The core column is connected with an elastic frame by means of guide posts; the elastic frame can be elastically stretched as per its own nature and can be in any of various types. The miniature lamp beads are arranged on the elastic frame. The elastic frame can be bent to make its width reduced to be able to place into the lamp bulb via the opening thereof, the elastic frame and the miniature lamp beads can be stretched into a predetermined shape in the lamp bulb. Thereby, limitation of opening of a glass lamp bulb as before can be gotten rid off, the space in the lamp bulb can be used as far as it can be to construct a more attractive decoration effect with many light spots.

Claims

1. A decorative lamp bulb comprising:

a) a glass lamp bulb having an end opening with a lateral width dimension;

b) a core column extending into an interior of the glass lamp bulb through the end opening, the core column having a plurality of flexible guide posts extending therefrom into the interior of the glass lamp bulb;

c) an elastic frame attached to the plurality of flexible guide posts, the elastic frame having a predetermined shape with a lateral dimension greater than the lateral width dimension of the glass lamp bulb, whereby the elastic frame is deformed to pass through the end opening of the glass lamp bulb and is restored to the predetermined shape by elasticity of the elastic frame; and

,

d) a plurality of light emitting devices mounted on the elastic frame.

2. The decorative lamp bulb of claim 1 wherein the light emitting devices comprise miniature lamp beads.

3. The decorative lamp bulb of claim 1 wherein the light emitting devices comprise light emissive diodes (LED).

4. The decorative lamp bulb of claim 1 wherein the core column includes a positioning flange abutting against the glass lamp bulb.
