An injection-molded integrated lamp string includes a power line and several lamp bulbs spaced apart on a power line. The lamp bulb comprises a lampshade, a lamp core body, and at least one insulation plastic piece. The lampshade is provided with an insertion portion, and the lamp core body is inserted into the insertion portion and protruded into the lampshade. The lamp core body is provided with at least one LED lamp filament, and both ends of the LED lamp filament are connected with a positive pole conductive wire and a negative pole conductive wire to form a semi-finished lamp bulb. The semi-finished lamp bulb, the positive pole conductive wire, and the negative pole conductive wire are integrally connected with the power line through injection molding. An injection plastic fusion body and the semi-finished lamp bulb are fused integrally through a mold to form a sealing insulation plastic head.

Illumination modules (530) are described for use during manufacturing processes and subsequent material processing steps. The illumination modules (530) may assist with implementing methods for performing quality assurance or defect detection while material (510) is being manufactured or processed. Methods are also described for utilizing an illumination module to facilitate the detection of material properties or conformations as a part of quality assurance or defect detection algorithms.

An LED bulb has an envelope, an electrical connector, a filament, and at least one electric wire. The envelope is hollow, sealed, and translucent and has a containing portion being enclosed, a neck portion disposed at the containing portion, and an envelope axis passing through the containing portion and the neck portion. The electrical connector is connected to the neck portion. The filament is inside the containing portion, is partially attached to an inner surface of the envelope, and has a light-emitting strip having multiple LEDs and an adhering layer disposed at the light-emitting strip and partially attached to the inner surface of the envelope. The at least one electric wire is electrically connected to the filament and the electrical connector.

A light-emitting device comprises a semiconductor stack comprising a first semiconductor layer, a second semiconductor layer, and an active layer formed between the first semiconductor layer and the second semiconductor layer; a first pad electrically connected to the first semiconductor layer; a second pad comprising multiple sidewalls electrically connected to the second semiconductor layer; and a metal layer formed on the semiconductor stack, wherein the metal layer surrounds the multiple sidewalls of the second pad and the metal layer is separated from the second pad.

The LED lamp has a relatively long, narrow configuration similar to that of CFL bulbs. Because the lamp operates at relatively high power and produces significant lumens, a significant amount of heat is generated by the LED assembly. The interior envelope of the lamp, defined in traditional CFL bulbs by the fluorescent tubes, is used to house a heat sink having a shape and dimensions to fit inside of the form factor of the CFL tubes. The heat sink substantially fills the interior space of the optically transmissive enclosure in order to provide maximum surface area for dissipating heat from the LEDs. A plurality of fins may extend from the heat sink to the exterior of the lamp to dissipate heat from the LEDs to the ambient environment.
