The inclined surface 151 is able to guide the horizontal bar 515 to reach the stopper surface 152 and the stopper surface 152 is vertical to the inserting direction of the horizontal bar 515.

[0038] Please refer to FIG. 2, FIG. 6 and FIG. 7. FIG. 6 is the exploded view illustrating the output cable 6 not assembled with the fastening strip 7 in accordance with one embodiment of the present invention. FIG. 7 is the sectional view illustrating the output cable 6 assembled with the fastening strip 7 in accordance with one embodiment of the present invention. In one embodiment, the downlight 100 further includes an output cable 6 and a fastening strip 7. The housing 1 has an accommodating portion 16 and the output cable 6 penetrates through the cable hole of the accommodating portion 16 to connect to the light source board 2. The output cable 6 should be long enough to connect to the light source board 2. The accommodating portion 16 is a protrusion structure protruding from the housing 1 and there is a space inside the accommodating portion 16. The fastening strip 7 is disposed in the accommodating portion 16 so as to fix the output cable 6 in the accommodating portion 16. The structure of the fastening strip 7 is simple, which not only can reduce the material cost and easy to install, but also can conform to the tension standard. As a result, the above structure can effectively reduce the overall cost of the downlight 100.

[0039] Please refer to FIG. 1, FIG. 8 and FIG. 9. FIG. 8 is the view illustrating the light source board 2 assembled with the housing 1 in accordance with one embodiment of the present invention. FIG. 9 is the sectional view illustrating the light source board 2 assembled with the housing 1 in accordance with one embodiment of the present invention. In one embodiment, the housing 1 includes a first ring portion 1a and a second ring portion 1b connected to each other. The cylindrical body 11 is disposed between the first ring portion 1a and the second ring portion 1b, such that an accommodating space 1c is formed between the first ring portion 1a, the cylindrical body 11 and the second ring portion 1b.

[0040] Please refer to FIG. 1, FIG. 8 and FIG. 9. In one embodiment, the light source board 2 is fixed on an inner surface of the second ring portion 1b and the light source board 2 is disposed in the accommodating space 1c. A portion of the light source board 2 is covered by the second ring portion 1b and the other portion of the light source board 2 is exposed from the second ring portion 1b. As the light source board 2 is exposed from the second ring portion 1b, the heat generated by the light source board 2 can dissipate in a short time. The above structure can significantly enhance the heat dissipation performance of the downlight 100 so as to avoid that the components inside the downlight 100 are deformed or deteriorate due to high temperature. As a result, the service life of the downlight 100 can be effectively increased and the performance of the downlight 100 can be also enhanced.

[0041] As set forth above, the outer edge of the light source board 2 contacts the housing 1. The housing 1 is made of a heat conducting plastic material and the thickness thereof is greater than or equal to 1.5 mm. The light source board 2 may be, but not limited to, a metal substrate, a fiberglass board or a composite-material substrate. As the light source board 2 is exposed from the second ring portion 1b, the heat generated by the light source board 2 can dissipate in a short time. In addition, the amount of the material for manufacturing the housing 1 can be reduced, so the cost of the downlight 100 can be decreased.

[0042] To sum up, according to the downlight having direct-press assembling mechanism of one embodiment of the present invention, the spring fastening members can be fixed on the housing by a force directly pressing the spring fastening members toward the housing. Accordingly, the difficulty of the assembling process thereof can be reduced and the assembling time can be decreased, which can effectively increase the work efficiency and reduce the manpower cost. In one embodiment, the output cable can be fixed by the fastening strip so as to make sure that the output cable can be stably fixed in the accommodating portion of the housing, which can reduce the material cost (reduces the number of the screws and wires of the downlight). Thus, the overall cost of the downlight can be decreased. In one embodiment, the light source board can be directly exposed in order to achieve great heat dissipation. Thus, the material consumption and the cost of the housing can be reduced.

[0043] It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed embodiments. It is intended that the specification and examples be considered as exemplary only, with a true scope of the present invention being indicated by the following claims and their equivalents.
