Reporters obtained the following quote from the background information supplied by the inventors: "The existing decorative lamps generally comprise a lampshade, a light emitting diode, conductive wires and a lamp holder.
"For such decorative lamps, one known structure is effectuated by integrated injection molding, i.e. a light emitting diode is disposed in a lampshade in a way such that two leads of the light emitting diode are led out of the lampshade through conductive wires and then the bottom of the lampshade and the connection portion between the conductive wires and the leads are injected with plastics to form a molded lamp holder into which the bottom of the lampshade and two lead-out conductive wires are over-molded, thereby producing the waterproof effect. For decorative lamps with such structure, it is necessary to deliver the bottom of the lampshade, at which a light emitting diode is disposed, to an injection molding machine for thermal injection-molding. As a result, the machining is inconvenient and the LED is easily damaged during heating.
"Another known structure is effectuated by an assembled structure, i.e. a LED is mounted using a soft core and inserted into a soft head installed with terminals and conductive wires to form an assembled lamp holder. With this, the machining is quite convenient. For decorative lamps with such structure, there are gaps at a coupling portion between the soft head and the soft core as well as a coupling portion between the soft head and the conductive wires so that it is impossible to be waterproof, causing that the LED leads and the terminals are oxidized to render poor contact."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "The object of the present invention is to provide a waterproof decorative lamp that is conveniently assembled.
"In one aspect, there is provided a decorative lamp comprising a lampshade, a luminophor and conductive wires connected with the luminophor; characterized in that, the decorative lamp further comprises: a wire trapper, one end portion of which is disposed between the conductive wires; and a housing with opened inner space, the wire trapper is disposed inside the inner space, the conductive wires extend out of an opened end of the inner space to be connected to an external power supply; wherein said one end portion of the wire trapper and an inner wall of the housing defining the inner space press and fix the conductive wires, and wherein the lampshade and the housing respectively include structures that cooperate to form a sealing assembly.
"In another aspect, there is provided a decorate lamp comprising: a snap-fit member having a throughhole, a luminophor, the bottom of the luminophor is disposed in the throughhole, the main body except for the bottom extending out of the snap-fit member; characterized in that, the decorative lamp further comprises: a wire trapper, one end portion of the trapper is disposed between conductive wires to space the conductive wires apart; a housing with an opened inner space for passage of the wire trapper and the conductive wires, the wire trapper is disposed in the inner space, the conductive wires extend out of one end of the inner space to be connected to an external power supply; wherein said one end portion of the wire trapper and the inner wall of the housing defining the inner space press and secure the conductive wires; wherein the snap-fit member and the housing respectively include structures that cooperate to form a seal assembly; and wherein the bottom of the luminophor has a dimension equal to or greater than that of the throughhole of the snap-fit member so as to form a tight cooperation with said throughhole.
"With the invention, the lampshade is pressed against the housing. The slots of the wire trapper and the inner hole of the housing work together to presses and secure the conductive wires.
