Although the conventional light bulb can achieve the function of switching between the far-light and the near-light, since the conventional light bulb uses the tungsten wire as the light-emitting unit 7, it is easily burned by high heat for a long period of use, has a short service life, and consumes electricity. High, and can not achieve the required brightness, so the known light bulbs still need to be improved.

Therefore, the object of the present invention is to provide a bulb which has a novel structure and can achieve sufficient illumination brightness, power saving, and long service life.

Thus, the new light bulb comprises a base, a base, an LED near light module, and an LED high light module. The base extends forwardly from the base and includes a first mounting section spaced from the base and a second mounting section intermediate the first mounting section and the base. The LED near-light module is mounted on one of the first mounting segment and the second mounting segment. The LED remote light module is mounted on the other of the first mounting segment and the second mounting segment, and the LED remote lamp module and the LED proximity lamp module illuminate in different directions.

With the innovative structure design of the present invention, the novel model can switch between the near lamp and the far lamp, and achieve sufficient illumination brightness, and has the advantages of power saving and not easy to burn, so the purpose of the novel can be achieved.

The second mounting section 22 is a columnar body extending longitudinally in the front and rear direction, and has a second mounting surface 221 on the side surface facing the second direction T2, and a second surface opposite to the second mounting surface 221 Cooling arc surface 222.

The first mounting surface 211 and the second mounting surface 221 face no In the same direction, the first direction T1 and the second direction T2 are sandwiched by 90° to 180°. In this example, the first direction T1 is 135° with the second direction T2, but is not limited thereto. The first heat dissipation arc surface 212 and the second heat dissipation arc surface 222 are respectively curved surfaces to provide a larger heat dissipation area.

The LED near-light module 3 is mounted on the first mounting surface 211 and can emit light in the first direction T1. The LED high-light module 4 is mounted on the second mounting surface 221 and can emit light in the second direction T2. The LED low-light module 3 and the LED high-light module 4 respectively have a plurality of light-emitting diodes (LEDs) capable of being driven to emit light, which have the advantages of high brightness, energy saving and power saving.
