Abstract: A method for making a lamp chain may include: a) providing a tooling provided with a cavity therein, wherein multiple lens-like holes spaced apart from each other at a predetermined distance are formed in the bottom of the cavity; b) placing a circuit board mounted with multiple illuminants in the cavity and keeping the circuit board away from the bottom of the cavity at a predetermined distance; wherein the multiple lens-like holes correspond to the positions of the multiple illuminants at the circuit board; c) injecting glue into the cavity until the glue fully fills the cavity; and d) solidifying the glue.

Abstract: In various embodiments, a self-ballasted light emitting diode (LED) tube may include an LED lamp body; and an LED driver module; wherein the LED driver module is configured to drive the LED lamp body for lighting; wherein the LED driver module and the LED lamp body are removably connected.

Abstract: The present invention discloses an LED module comprising: a waterproof enclosure; an LED accommodated in the waterproof enclosure; a wire for coupling the LED module with other LED modules and a driver; and a radiating unit set in the bottom of the waterproof enclosure and exposed to the external environment. The invention further provides an LED chain comprising the above said LED module and a driver coupled with the LED module. The LED chain according to the invention may have a high waterproof level, for example, IP65. The heat generated during the operation of the high power LED module may be transmitted to the external environment in time via a heat sink set on the LED module, thereby effective thermal management for the LED module and a long service life of the LED module may be obtained. Moreover, the finish surface of the driver may be made handsome by encapsulating the driver through the low pressure molding.
