Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of lighting technology, and more particularly to a lantern-shaped string light assembly for lighting lamps. [Background Technology]
[0002] With continuous social progress and development, and the rising living standards of consumers, various types of lighting fixtures have entered all aspects of consumers' lives, work, and entertainment. However, most existing string lights are simply small props used to enhance portrait artwork; they are easy to obtain, add creativity, enliven the artwork, and create a warm and dreamy scene, making the image more inviting. If multiple string lights are connected in parallel along a main line, they form a string light assembly. Each string light assembly includes a lampshade, an LED panel, an inner cover, and a lamp housing.
[0003] Because the lampshade, inner cover, and lamp housing are connected together by threads, after a period of use, the threads on the surface of the lampshade, inner cover, and injection molded body are easily worn and oxidized. As a result, gaps are created between the parts inside the lamp housing, making it easy for moisture and dust to accumulate inside the lamp housing. Consequently, the waterproof and dustproof performance of the entire lamp housing is relatively poor. [Utility Model Content]
[0004] In view of this, the technical problem to be solved by this utility model is to provide a lantern-shaped light string assembly that not only improves waterproof and dustproof performance, but also improves heat dissipation and light brightness.
[0005] To address the aforementioned technical problems, the utility model application in this case provides a lantern-style string light assembly, comprising a transparent cover, a light panel, a power supply, a plurality of screws, a light housing, and power supply connection wires disposed at both ends of the light housing; the light housing includes a bottom shell located at the upper end and a top shell mounted at the lower end of the bottom shell; the bottom shell includes a bottom shell body, a hanging hole disposed at the top of the bottom shell body, and power connection holes disposed at both ends of the bottom shell body; the bottom shell body is composed of an inverted trapezoidal hollow light basin with an upper-larger and lower-smaller interior; the top shell includes a panel cover body disposed at the upper end, and a bottom shell positioning post disposed on the back of the panel cover body that contacts the bottom shell body.
[0006] The lamp power supply is installed inside the bottom shell, and a heat sink is provided between the upper inner wall of the bottom shell for the lamp power supply; the heat sink is composed of multiple strip-shaped heat sinks stacked on top of each other; the strip-shaped heat sinks are stacked on top of each other to form a stepped heat sink; the strip-shaped heat sinks are made of aluminum block material.
[0007] The lamp panel is mounted on the heat sink, and a reflector is also provided inside the bottom shell; the reflector is composed of a lamp basin that is smaller at the top and larger at the bottom; and edge covers are provided around the four edges of the lamp basin.
[0008] The reflector is placed on top of the heat sink, the lamp plate is placed inside the reflector, the faceplate is installed on the lower end face of the reflector, a mesh cover is provided on the lower end face of the faceplate, and the transparent cover is installed between the mesh cover and the faceplate.
[0009] The intersection of the lower end face of the bottom shell and the upper end face of the top shell, and the intersection of the lower end face of the top shell and the upper end face of the mesh cover are respectively coated with sealant to improve waterproofing and sealing effect; the lamp board and lamp power supply are placed directly on the heat sink.
[0010] The lamp panel includes a lamp substrate and a plurality of LED beads for emitting light are soldered to the back of the lamp substrate.
[0011] During installation, the lamp power supply wires are connected to both ends of the bottom shell, the heat sink is installed inside the bottom shell, the lamp power supply and the lamp board are installed on the heat sink, the reflector is installed inside the bottom shell and above the lamp board, the front shell is installed on the lower end face of the bottom shell, the transparent cover is installed on the lower end face of the front shell, the mesh cover is installed on the lower end face of the front shell, and the transparent cover is installed between the front shell and the mesh cover.
[0012] The utility model application in this case has the following beneficial technical effects: Since the lamp housing is composed of a bottom shell placed at the bottom end and a top shell installed on the bottom shell, at the intersection between the lower end surface of the bottom shell and the top shell, or at the intersection between the lower end surface of the top shell and the upper end surface of the mesh cover, the bottom surface of the top shell is coated with sealant. The purpose of the sealant to seal the surface at the intersection is to improve the waterproof and dustproof performance.
[0013] Furthermore, since the lamp power supply is installed inside the bottom shell, a heat sink is provided between the upper inner wall of the bottom shell for the lamp power supply; the heat sink is composed of multiple strip-shaped heat sinks stacked on top of each other; the strip-shaped heat sinks are stacked on top of each other to form a stepped heat sink; the strip-shaped heat sinks are made of aluminum block material, thereby enabling the heat sink to conduct the heat released by the lamp power supply to the outside, so as to achieve a good effect of uniform temperature, thereby improving the heat dissipation effect.
[0014] Furthermore, since the lamp panel is mounted on the heat sink, a reflector is also installed inside the bottom shell; the reflector is composed of a lamp basin that is smaller at the top and larger at the bottom; and edge covers are provided around the four edges of the lamp basin. In this structure, the addition of the reflector makes the light beam more focused, and the downward-facing light is brighter, thereby achieving the purpose of improving the luminous brightness.
