In addition, the puddle lamp, which is easy to manufacture and combine according to an embodiment of the present invention, is easy to manufacture by manufacturing each component without screws, and a method in which each component is sequentially stacked and coupled to the inside of the housing 10. By adopting it, the overall manufacturing process of the puddle lamp 1 can be shortened, thereby enabling efficient production.

In addition, a screw is not separately formed for each component, but is combined by a simple lamination method, thereby minimizing the gap between the combined components, thereby increasing the waterproofing effect, and attaching the heat sink 80 to the lower end of the housing 10 through the use of an adhesive. In combination, the entire housing 10 is waterproofed to prevent water from seeping into the housing 10, thereby increasing the overall durability of the puddle lamp 1.

Such a puddle lamp, which is easy to manufacture and combine, includes a housing 10, a PCB 20, an LED 21, a reflector module 30, a first lens module 40, a logo mask 50, and a second lens. A module 60, a third lens module 70, and a heat sink 80 are included.

Hereinafter, components constituting a puddle lamp that is easy to manufacture and combine will be described in detail with reference to FIGS. 2A to 9B.
