Abstract: A PLV lamp includes a lamp cup, a lamp body, and a lamp cap, wherein the lamp cup is rotationally connected with the lamp body, and the lamp body is stretchable and matched with the lamp cap. The rotatable connection between the lamp cup and the lamp body is realized through two movable shafts. The two movable shafts have a gap formed therebetween and are arranged at a bottom of the lamp cup. The lamp body is provided with a movable shaft base to be matched with the gap, and the two movable shafts are connected with the movable shaft base.

Abstract: This invention provides an integrated LED energy-saving lamp, a manufacturing method thereof and a corn lamp. The LED energy-saving lamp comprises at least one tube, at least one baseplate, a plurality of LED lamp beads and a heat conductive adhesive. Each tube comprises two parallel first parts and a second part for connecting the two first parts. Each baseplate comprises two parallel branch parts, located on the same plane, and a connecting part for connecting with the two branches; the two branches are respectively located in the two first parts of the tube. The LED lamp beads are respectively arranged on the two branches. The heat conductive adhesive is pasted between the two branches and the internal wall of the tube.
