New description: [New technical field] A lighting bulb, especially a wide-area light-emitting diode bulb. [Prior Art] Since the light-emitting diode has the advantages of low energy consumption, energy saving, long life, durability, shock resistance, small volume, and quick response. The traffic lights, flashlights or decorative lights on the roads have been changed to light-emitting diode modules to illuminate. As for automotive lamps such as automobile taillights and xenon lamps, LED modules have also been widely used. However, since the light-emitting diode emits light from a point source, the light-emitting diode of the present invention has a narrow illumination angle and a illuminating unevenness under the concentrating light design using most of the light-emitting diodes. . For example, due to the light path design of the light-emitting diode, it only has an illumination angle of about 180 degrees, and most of the light-emitting diode lamps require a heat sink, such as a heat sink fin, to make it Part of the light can only illuminate the forward and lateral areas. For example, when such a light-emitting diode bulb is mounted on a ceiling, the light it projects can only illuminate the area below, but the area above the bulb will only partially scatter or diffuse light. It will give the average user a feeling of dimness. If you want to eliminate the feeling of insufficient illumination, the common practice 3 :: increase the brightness with high-power LEDs, however, ~ go to the private power consumption increase 'for the radiator will be built: the test' It is necessary to use the better effect but the higher price!! Dissipate the extra heat, which will cause the increase of manufacturing cost: the general radiator is used in consideration of the cost, and the light-emitting diode is easy to cause the actual service life due to the heat.
