Dual-modular downlight
Disclosed herein is a downlight, which includes an optoelectronic module and a rim module. The optoelectronic module includes a light source driving board, a back housing, and a front housing. The light source driving board is disposed between the back housing and the front housing. The light source driving board includes a light-emitting diode unit and a driving circuit. The rim module has a central opening for accommodating the optoelectronic module. The rim module is not integrally formed with the optoelectronic module.
1. A downlight, comprising,
an optoelectronic module, comprising a light source driving board, a back housing, and a front housing, wherein the light source driving board is disposed between the back housing and the front housing, and the light source driving board comprises a light-emitting diode unit and a driving circuit; and
a rim module, having a central opening configured to accommodate the optoelectronic module;
wherein the central opening of the rim module comprises a circular inner flange, and when the optoelectronic module is inserted into the central opening of the rim module, the circular inner flange rests against and covers the peripheral of the front housing by engaging a tubular wall of the circular inner flange with a corresponding external surface of the front housing, and another type of the rim module with the same size of the circular inner flange is replaceable for constructing products for different standards.
2. The downlight according to the claim 1 , wherein the rim module comprises a fastener, wherein the fastener is fixed on the tubular wall.
3. The downlight according to the claim 2 , wherein the fastener is a metallic fastener.
4. The downlight according to the claim 1 , wherein the front housing is a diffusion plate.
5. The downlight according to the claim 1 , wherein the light source driving board comprises a plurality of light-emitting diode units arranged in a ring-shape.
6. The downlight according to the claim 1 , wherein the rim module comprises outer ring, wherein the outer ring is a circular ring.
7. The downlight according to the claim 1 , wherein the rim module comprises outer ring, wherein the outer ring is a rectangular ring.
