Description of the Invention: [Technical Field] The present invention relates to an improvement of an LED bulb, and more particularly to an LED bulb design having multi-directional projection and excellent heat dissipation function. [Prior Art] Conventional LED bulbs, because the internal LED light-emitting elements are all disposed toward the front end, the light sources are concentrated in the same direction of the front end, the peripheral light source will be weak, easy to have insufficient brightness, and the overall illumination brightness is uneven. Although the LED bulb has the advantages of low power consumption, but the heat resistance is low, it is necessary to solve the heat dissipation problem; for example, the LED bulb manufactured by Philips is known to be a molded metal heat sink seat for providing Heat dissipation, but the overall bulky and expensive, the heat dissipation effect is very limited, it is not practical. According to the recent development trend, the general LED or high-power LED light-emitting component bulb has gradually replaced the traditional tungsten filament heating bulb, and related technologies are also constantly improving. However, it is known that the LED bulb utilizes the heat of the LED body and its power supply lead or circuit substrate. Passive heat dissipation, after long-term use, will accumulate temperature rise, easily lead to LED electrical poor or damaged, especially as the number of LED light-emitting components increases relative to the temperature, the heat dissipation problem will be even more serious. SUMMARY OF THE INVENTION The main object of the present invention is to provide an LED bulb design with multi-directional projection, comprising a lamp cover, a heat conducting base, a plurality of heat sinks, a heat conducting component and a plurality of LED light emitting components, the heat conducting base The periphery of the seat is combined with a plurality of heat sinks, and the heat conductive base has a tight fit to accommodate the guide 201113468
