Abstract

A light bulb comprising a structure characterized in having a light reflecting plate and a light-emitting repository configured on a circuit board. Upon the circuit board being disposed in a base of the light bulb, connecting pins are employed to connect the circuit board to the base. After electricity is supplied to entire light-emitting device, rays of light directly emitting from the light-emitting repository are rectified by means of an elevation of the light reflecting plate, furthermore, an inclined surface of the light reflecting plate is employed to control the rays of light emitted at an angle greater than direct emittance angle, thereby achieving uniform distribution of the rays of light, and thus enhancing brightness and degree of uniformity thereof.

Claims

1. A light bulb comprising a structure comprising a light reflecting plate and a light-emitting repository configured on a circuit board, and upon the circuit board being disposed in a base of the light bulb, connecting pins are employed to connect the circuit board to the base;

after electricity is supplied to entire light-emitting device, rays of light directly emitting from the light-emitting repository are rectified by means of an elevation of the light reflecting plate, furthermore, an inclined surface of the light reflecting plate is employed to control the rays of light emitted at an angle greater than direct emittance angle, thereby achieving uniform distribution of the rays of light, and thus enhancing brightness and degree of uniformity thereof.

2. The light bulb as claimed in claim 1, wherein the light-emitting repository comprises and is constructed to include a light-emitting diode, an incandescent diode, a small-scale light bulb, and other related light source elements applied in illumination components.

3. The light bulb as claimed in claim 1, wherein the light-emitting device is installed in an autocar lamp, lighting employed indoors or outdoors, a street lighting, a desk lamp, and other related illumination sources applied in lighting equipment.

4. The light bulb as claimed in claim 1, wherein the bulb includes a transparent covering, a fluorescent-coated material covering, a ground material covering and other related coverings applied in exterior coverings of light bulbs.

5. The light bulb as claimed in claim 1, wherein the light reflecting plate is further configured with light reflecting plates adapted as an elevation and an inclined surface defined at differing angles, thereby facilitating changing area and brightness of the bulb upon which the rays of light are projected onto.
