Abstract
The present invention provides a method for constructing an LED bulb (102) with high interchangeability and universality, an integral LED bulb (102) and a lamp. A silver paste printed circuit (4) is embedded on a heat conductive bracket (3) sintered by a nonmetal heat conductive material and provided with a cooling fin, and then an LED chip is welded on the silver paste printed circuit (4) or a drive chip is further welded thereon to form the LED bulb (102). The bulb may operate independently, so that the LED bulb (102), the lamp and a lighting control product are independently produced and used, which greatly reduces manufacturing links of LED lighting products, improves mass production and facilitates the industrialization of LED energy-saving lighting products.
