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.
