Description of the Invention: [Technical Field] The present invention relates to a light-emitting diode bulb, particularly to a light-emitting diode bulb having a full-circumferential illumination and an active heat dissipation mechanism. [Prior Art] Light-emitting diodes with low power consumption, high energy conversion efficiency, long life and no mercury pollution have been applied to traffic signs, lights and street lamps, and the trend of energy saving and carbon reduction Under the light, LED light bulbs are seen as replacing the incandescent bulbs and fluorescent lamps, and become the mainstream of future home lighting. To cater to the above trends, manufacturers have developed some light-emitting diode bulbs. Figure 1 illustrates a schematic diagram of a conventional light-emitting diode bulb 10. The light-emitting diode bulb 10 includes a planar substrate 13 , a light-emitting diode 14 disposed on the planar substrate 13 , and a heat sink 12 for providing heat dissipation of the light-emitting diode 14 for connecting an external power source and thereby providing The light-emitting diode 14 is connected to the power supply terminal 11 and the light cover 15 for isolating the light-emitting diode 14. The light-emitting diode 12 of the conventional art light-emitting diode bulb adopts a planar layout, and this planar layout has two kinds of defects: First, the layout of the planar layout can be utilized, that is, in a certain illumination. Under the area, the number of the LEDs 14 cannot be expanded to increase the brightness; secondly, the arrangement of the heat sink 12 of the LEDs 14 is also limited by a limited plane boundary, so the required heat dissipation area is required. Next, the volume of the heat sink 12 will be increased, thereby increasing the weight of the LED bulb 10. In addition, a fan (not shown) can be used in the heat dissipating device 12 to achieve better heat dissipation by forced convection. However, the illuminating diode of the prior art 201031862 diode 12 and the heat sink 12 are used. After being assembled and assembled, it is placed together in the lampshade 15 because the service life of the light-emitting diode 14 is long. The light-emitting diode lamp 10 may be completely replaced due to the failure of the fan (not shown), resulting in unnecessary waste. Moreover, the design of the light-emitting diode bulb 10 of the conventional heat-dissipating device 12 which is easy to accumulate dust and is known for a long time cannot be easily cleaned, and the light-emitting diode 14 is finally reduced due to the heat dissipation efficiency of the heat sink 12 being lowered. Life expectancy is reduced. In the absence of various light-emitting diode bulbs of the above-mentioned conventional techniques, it is necessary to propose a new and improved light-emitting diode bulb to improve the efficiency and utilization rate of the light-emitting diode bulb. SUMMARY OF THE INVENTION The present invention provides a light-emitting diode bulb that utilizes a modular design to make it easier to clean and replace faults of individual modules, thereby reducing the cost of use.

Referring to FIG. 5 and FIG. 8 , the recessed lamp 80 includes the above-mentioned light-emitting diode bulb 2 , a female socket for fixing the light-emitting diode bulb 20 and an external power supply for providing the light-emitting diode bulb 2 . 8 丨 and a reflector 82 ′ for projecting the illuminating light of the LED bulb 2 , wherein the connector 51 of the LED bulb 20 is received in the female socket 81 . 201031862 The above-mentioned 'setting a light-emitting diode on the surface of a columnar body to form a three-dimensional arrangement' can solve the limitation of the planar arrangement, "the length of the column can be arbitrarily extended" to increase the number of arrangement of the light-emitting diodes. Therefore, the brightness of the projected unit area can be effectively improved. A heat dissipation structure is disposed in the cylindrical case, and the heat dissipation efficiency is optimized by using the air flow through the heat dissipation structure. The modular design of the illuminating part and the lamp body makes it easy to replace cleaning and faults, thereby reducing the cost of use. The technical contents and technical features of the present invention have been disclosed as above, but those skilled in the art can still make various substitutions and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be construed as being limited by the scope of the appended claims. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a conventional light-emitting diode bulb; FIG. 2 is a perspective view showing a light-emitting diode bulb according to an embodiment of the present invention;
