Abstract
The present invention discloses a method for constructing a universal LED bulb, a flange snap ring type LED bulb and a lamp. A heat conductive bracket (3) with a flange is used as a structure supporting main body of the bulb to establish an optical engine core member of the LED bulb. An inner snap ring (81) fixed to the heat conductive bracket (3) is used to support the optical engine core member in an auxiliary manner. The optical engine core member is composed of the heat conductive bracket (3), an optical engine module (4), the inner snap ring (81), an inner cover (6), an electric connector (11) and a light distribution optical lens (7). The optical engine module (4) is made up of an optical engine die plate, an LED chip and a relevant wiring by bonding and packaging, or is further integrated with a power supply drive chip.
