Description of the Invention: [Technical Field] The present invention relates to a light-emitting diode bulb, and more particularly to a light-emitting diode bulb having a constant current circuit. [Prior Art] After Edison invented the world's first light bulb, the light bulb has become an indispensable part of everyday life for more than a hundred years. Even today, when it has entered the 21st century, most of the lighting devices widely used in the society are mostly tungsten filament bulbs. However, traditional tungsten filament bulbs can only be used for about one thousand hours. Shortcomings such as scalding and breakage, plus 91% of their energy, have been useless. In today's environment where environmental protection is paramount, it is a contradiction to be able to make good use of energy lighting equipment. Therefore, tungsten filament bulbs have gradually been eliminated and replaced by lamps composed of "light emitting diodes". A light-emitting diode bulb, which is the biggest difference from a conventional light bulb, is that it can be used continuously for 100,000 hours, and almost all of the energy is used to emit light without dissipating a lot of useless heat due to heat generation of the bulb, thereby knowing Its service life is 100 times that of the traditional light bulb, and the monthly consumption of the light bulb is only 10% of the light bulb, which means that people can save a lot of electricity costs, while the voltage of the light-emitting diode is only 4 volts. Therefore, there is no danger of touching the package. It can be seen that the light-emitting diode bulb will soon replace the status of the traditional filament light bulb. At present, a common light-emitting diode bulb is driven by a step-down transformer through a rectifier circuit, and a plurality of light-emitting diodes are driven by a low-voltage direct current 4 1293807, and the number of series of light-emitting diodes is excellent. Change, the transformer's wheel out 1 is also Pil changed, and the pressure drop tank is not only bulky, but also has the shortcomings of Rong County's brigade ^ X..., so there will still be some thunder and can be wasted. Going again, the ancient ~ Beidian, the common light-emitting diode structure on the market, as shown in the fourth figure, includes _ with anode pin (3 ",) and cathode pin (3 1 2') The metal bracket 'is formed at the top end of the anode pin (31 1 1') of the metal bracket with a bracket portion, and a crystal cup is formed on the bracket portion (3)

Uneven phenomenon. As mentioned on the wire, it can be seen that the current light-emitting diode bulb has not reached the mature state. Therefore, if it can provide a non-heating, power-saving, small volume, uniform illumination, and can provide temporary and appropriate illumination in the event of power failure. The polar bulbs will greatly reduce the size of the lighting equipment and provide a more environmentally friendly and safer environment.
