Description
Fixture Device and Downlight Having the Fixture Device Technical Field
The present invention relates to a fixture device and a downlight having the fixture device.
Background Prior Art
The downlight is a common illuminating device and widely used in offices, halls and malls. The downlight is embedded in the roofs or walls so as to ensure a decorative effect.
In recent years, with the wide applications of LED lamps, LED lamp light sources also start to be used more and more in downlights. As a heat sink is needed for heat dissipation of the LED, an LED downlight will use aluminum alloy as the heat sink, then the LED downlight is heavier than a traditional downlight due to such heat sink. Therefore, a reliable structure is demanded to fix the downlight in a mounting hole of the ceiling so that it will not fall off.
There are two prior art fixture devices for fixing the downlight, wherein a downlight body and the fixture device are made into one piece and fastened by using an elastic force. A plate spring is used to fix the whole downlight as shown in Fig. 1, and a snap spring is used to fix the whole downlight as shown in Fig. 2. The common ground of the two methods above lies in using the elastic force to fix the downlight on the ceiling, while one disadvantage is that the downlight will easily fall off when it is heavy since it de-
201124483
pends upon the elastic force to fix the downlight on the ceiling .
Summary of the Invention
The object of the present invention lies in providing a fixture device that can support a relatively heavy downlight, will not easily damage the ceiling, and can be widely adapted to ceilings of different thicknesses.
A fixture device for a downlight is provided according to the present invention, characterized in that the fixture device comprises a support frame connected to a downlight body and a fastening mechanism mounted on the support frame, and the fastening mechanism is moveable with respect to the support frame between a mounting position where the fastening mechanism is taken back with respect to the support frame and a fastening position where the fastening mechanism is stretched out with respect to the support frame and is capable of tightly pressing a ceiling.
The present invention provides a fixture device that replaces an elastic force to fix a downlight on a ceiling. The fixture device comprises a support frame connected with the downlight body integrally or separately and a fastening mechanism mounted on the support frame, and the downlight is fixed by means of the fastening mechanism. In the present invention, as the fastening mechanism is removable with respect to the support frame, it can move to the mounting position and the fastening position. In the mounting position, the fastening mechanism is adjusted to be adapted to pass through a mounting hole in the ceiling, i.e., the fastening mechanism is adjusted to be taken back with respect to the
201 124483
support frame. After the downlight is mounted in the mounting hole of the ceiling, the fastening mechanism can be moved from the mounting position to the fastening position, that is, the fastening mechanism is stretched out with respect to the support frame to tightly press the downlight on the ceiling. That is to say, the fastening mechanism has different positions and/or orientations with respect to the support frame in the mounting position and the fastening position, which facilitates to meet different requirements, i.e., mounting requirement and fastening requirement, via the positions and/or orientations. Compared with the prior art that the downlight is fixed on the ceiling by using an elastic force, in the present invention, a bigger bearing force is generated and a heavier downlight can be supported.
In one preferred solution of the present invention, the support frame comprises a first guide portion and the fastening mechanism comprises a second guide portion, and the first guide portion guides the second guide portion between the mounting position and the fastening position. As a result of the cooperation of the first guide portion and the second guide portion with each other, a relative movement between the fastening mechanism and the support frame is easily realized and it is easily realized that the fastening mechanism has different positions and/or orientations with respect to the support frame.
In one preferred solution of the present invention, the fastening mechanism comprises an adjusting unit and a pressing unit configured as the second guide portion, and the adjusting unit is engaged with and drives the second guide portion. The adjusting unit drives the second guide portion to force the second guide portion to be guided, for instance, the sec-
201 124483
ond guide portion is stretched out in the fastening position to apply a pressure.
Preferably, the second guide portion comprises a first portion and a second portion, the first portion is engaged with the first guide portion, and the second portion is engaged with the adjusting unit. Thus, the structure design is simplified, and connecting structures between the second guide portion, the first guide portion and the adjusting unit are simplified, and movements are effectively transferred.
Preferably, the adjusting unit comprises an adjusting screw and a screw hole is opened in the second portion to cooperate with the adjusting screw. Thus, the structure design is simplified, and the adjustment is facilitated. By means of a mutual action of the adjusting screw and the screw hole, a movement of the adjusting screw is transferred to the second guide portion opened with the screw hole, for example, by guiding the second guide portion downwardly, the first portion of the second guide portion is used finally to be pressed on an inner surface of the ceiling.
Preferably, the adjusting unit further comprises a stop nut, and the adjusting screw passes through the screw hole to be engaged with the stop nut. The stop nut can prevent disengagement of the adjusting screw and the screw hole when the adjusting screw and the screw hole go beyond an adjusting route caused by over-adjustment of the adjusting screw and the screw hole.
Preferably, the second guide portion is an L- shape slide block. A minor shaft portion of the L-shape slide block, e.g., as the first portion of the second guide portion, has a
201 124483
portion thereof configured as a pressing end that can tightly press the ceiling, so that a bigger pressing force is applied on the ceiling. A major shaft portion of the L- shape slide block, as the second portion of the second guide portion, has a portion thereof that can be opened with the screw hole .
Preferably, the support frame is a guide plate, and the first guide portion is a slide slot opened on the guide plate. As the L-shape slide block slides in the slide slot, it is convenient to mount the downlight into the mounting hole in the ceiling in the mounting position, and a transfer from the mounting position to the fastening position can be easily realized when fastening is needed.
Preferably, the slide slot has a bent slide slot portion and a vertical slide slot portion in sequence from top to bottom. By configuring the slide slot portion to have such two portions, when guided in the bent slide slot portion, the fastening mechanism is located in the mounting position where the fastening mechanism is taken back with respect to the support frame, and when guided in the vertical slide slot portion, the fastening mechanism is located in the fastening position where the fastening mechanism is stretched out with respect to the support frame and tightly presses an inner surface of the ceiling.
Preferably, the guide plate and the downlight body are removably connected, which thus improves the universality of the fixture device cooperating with different types of downlights. At least one fastening groove is opened on the guide plate, and the guide plate can be fixed on the downlight body by using at least one fastening piece passing
201 124483
through the at least one fastening groove.
The present invention further relates to a downlight comprising a downlight body and the fixture device with the above characteristics. Preferably, the downlight is an LED downlight. Preferably, the downlight body and the fixture device are removably connected.
The fixture device of the present invention can support a relatively heavy downlight, make it not easy for the downlight to fall off, will not easily damage the ceiling, and can be widely adapted to ceilings of different thicknesses, and therefore has prominent advantages.
