[0022] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figure 1 This embodiment provides a novel downlight, including a heat dissipation housing 1 , an integrated light board 2 and a lens 3 .

[0024] Among them, Figure 3 The integrated light board 2 has two layers, namely an inner plate 20 and an outer plate 21 arranged up and down, and the inner plate 20 and the outer plate 21 are connected by a connecting plate 22, that is, the integrated light board 2 is integrally formed and then divided into a two-layer structure of an inner plate 20 and an outer plate 21 by stamping, and lamp beads are respectively arranged on the inner plate 20 and the outer plate 21, and the integrated circuit is arranged on the inner plate 20.

[0025] In this embodiment, in detail, a positioning cavity 10 is formed on the inner bottom surface of the heat dissipation housing 1, and the inner diameter of the positioning cavity 10 matches the outer diameter of the inner plate 20;

[0026] Secondly, if Figure 2 A positioning boss 11 is formed on the outside of the positioning cavity 10, and an avoidance groove 12 is provided on the positioning boss 11. A wire outlet hole 13 is provided on the avoidance groove 12, and the outer diameter of the outer plate 21 is smaller than the outer diameter of the positioning boss 11. When the integrated light board 2 is built into the heat dissipation housing 1, the inner plate 20 is appropriately placed in the positioning cavity 10, the connecting plate 22 is located in the avoidance groove 12, and the outer plate 21 is attached to the positioning boss 11. After the connecting plate 22 is limited in the avoidance groove 12, the integrated light board 2 is prevented from moving in the heat dissipation housing 1, and the assembly of the integrated light board 2 is simple and quick.

[0027] In addition, if Figure 4 The lens 3 is snap-fitted and fixed on the opening of the heat dissipation shell 1, and the inside of the lens 3 abuts against the surface of the integrated light board 2. Specifically, the lens 3 includes a main body 30 and a frustum 31 integrally formed at the center of the bottom surface of the lens 3. The outer diameter of the main body 30 is matched with the inner diameter of the opening of the heat dissipation shell 1. When the lens 3 is snap-fitted on the opening of the heat dissipation shell 1, the frustum 31 abuts against the upper surface of the inner layer plate 20, further limiting the integrated light board 2 in the axial direction, completing the overall assembly of the downlight. It can be seen that no screws are required in the assembly process, which simplifies the convenience of disassembly and assembly.

[0028] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
