The LED lamp bulb housing (1) and the stem (2) are vacuum-sealed to form a vacuum-sealed cavity. The LED light-emitting bar (3), the driver (4) and the lamp holder (5) are electrically connected. The vacuum-sealed cavity is filled with helium, argon, or a helium-argon mixture. The LED lamp bulb housing (1) is semi-transparent or partially transparent, and is directly connected to the lamp holder (5). The LED chip (7) is combined with an integrated or non-integrated component, the stem (2) and a metal wire, and then is connected to the driver. According to the LED lamp bulb, the connection modes of the light-emitting bar (3) are diversified, the types of the lamp bulb housing (1) and the lamp holder (5) are diversified, and accordingly, the universality of the product is improved, and the costs are reduced.
