Description of the Invention: [Technical Field] The present invention relates to a light-emitting diode bulb, and aims to provide a light-emitting diode bulb capable of rotating a lamp cap and a joint within a limited angle, Rotating mechanism. [Prior Art] According to the 'light-emitting diode', its power saving, long life, low driving voltage, and fast reaction rate, it has gradually become one of the fastest growing light-emitting components, with LEDs (IJED). The rapid advancement of technology, coupled with the maturity of related peripheral integrated circuit control components and heat dissipation technology, has led to the diversification of the application of light-emitting diodes. 'Because of the traditional bulb-type lighting fixtures, mainly based on incandescent bulbs, traditional incandescent bulbs have a variety of different specifications according to the wattage, but most of them have a round head' and are set at the end of the round head. There is a screw joint for screwing into the bulb holder; therefore, the similar light-emitting diode bulb structure is mostly as shown in the first figure, and a plurality of light-emitting diode components are arranged inside a lamp cap 11 (not shown). And a joint 12 of a screw joint type is formed at one end of the base 11 for screwing with the existing bulb holder 2 . However, similar to the conventional light-emitting diode bulb, the light-emitting diode element disposed inside the lamp holder U is configured on a substrate in a specific arrangement manner, so that only the substrate is provided with the light-emitting diode element. One side has a lighting effect; so that when the conventional light-emitting diode bulb is mounted on the bulb holder 2, it is possible that the light is not directed to the intended direction due to the difference in the depth of the spiral, thereby lowering the light-emitting diode The practicality and ease of use of the bulb 10. SUMMARY OF THE INVENTION In view of the above, it is a primary object of the present invention to provide a light-emitting diode bulb that can rotate a lamp cap and a joint within a limited angle, thereby adjusting the direction of illumination of the light source, and a rotating mechanism associated therewith. In order to achieve the above object, the light-emitting diode bulb of the present invention has a lamp cap for 201104142 to be connected to her coffee, and a wire-connected wire to form a joint and a light-emitting diode; == set at _ :: The shaft tube is sleeved relative to the inner ring of the sleeve, so that the lamp holder and the joint are connected with the "'radial groove 2 U.
