DETAILED DESCRIPTION

[0058] In some embodiments, a lighting apparatus includes a main housing, a light module, a ventilating fan and a fixing frame.

[0059] Please refer to FIG. 6, which shows an example of a fixing frame 61. The fixing frame 61 has two telescopic levers 601, 602. Similarly, the telescopic lever 602 has a first part 6021 and a second part 6022. The telescopic lever 601 has a first part 6011 and a second part which may be moved to change a total length of the telescopic lever 601. There are various ways to implement such telescopic lever, e.g. using two tubes to move with each other, or a first part of a telescopic lever moving along a sliding track disposed on a second part of the telescopic lever.

[0060] FIG. 7 shows a dimension change by moving the first part with respect to the second part of the telescopic lever 601. It is clearly to compare FIG. 6 and FIG. 7 to see a total length 6013 of the fixing frame is changed.

[0061] The main housing has a fan bracket and a light bracket.

[0062] Please refer to FIG. 8. FIG. 8 shows a main housing 607 has a fan bracket 6071 and a light bracket 6072.

[0063] The light module 6061 is disposed to the light bracket 6072 for emitting a light 6061 outwardly to an illuminated space 6066.

[0064] The ventilating fan 605 is attached to the fan bracket 6071.

[0065] The ventilating fan 605 has an air passage 6062 partly exposed to the illuminated area 6066 for air to flow passing the air passage 6062 driven by the ventilating fan 605.

[0066] The fixing frame 61 holds the main housing 607 and is used for fixing to one of multiple types of installation platforms. For example, a ceiling with or without adjacent beams may be different installation platforms.

[0067] In the example of FIG. 8, a ceiling plate 610 is the installation platform.

[0068] The main housing 607 may be detachable from the fixing frame 61. In such design, the fixing frame may be installed first. In addition, the different main housing may be selected to meet different requirements.

[0069] Please refer back to FIG. 6.

[0070] The fixing frame 61 has two telescopic levers 601, 602 arranged in parallel for changing a spanning diameter to fit different installation platforms. FIG. 7 shows an example of the spanning diameter 6013.

[0071] The main housing is attached on the fixing bracket, which is explained and illustrated in FIG. 8 as described above.

[0072] In FIG. 6, the fixing frame has a pair of gear tracks 6037, 603 and a pair of gear blocks 6047, 604.

[0073] FIG. 8 shows another view of the example in FIG. 6. In FIG. 8, a bottom 6041 of the gear block 603 engages the installation platform, e.g. the ceiling plate 610.

[0074] The gear block 603 is movable along the gear track 604 to adjust a relative position 6041 of the fixing frame 61 to the installation platform, e.g. the ceiling plate 610.

[0075] In some embodiments, the gear block 603 has an elastic unit 609 for elastically engaging the installation platform.

[0076] In some embodiments, the elastic unit 609 is a U-shape clip with a bottom side pressing the installation platform, as shown in FIG. 8.

[0077] In some embodiments, the elastic unit is made of metal material for transmitting heat of the main housing to the installation platform.

[0078] In FIG. 8, multiple protruding clips 621 extend from edges of the fixing frame 61 to press to a bottom side of the ceiling plate 610 of the installation platform while the bottom of the gear block 603 engages a top side of the ceiling plate 610 of the installation platform so as to firmly fix the fixing frame 61 to the ceiling plate 610 of the installation platform.

[0079] In some embodiments, the gear track includes a fork structure defining a track passage for inserting the gear block.

[0080] FIG. 3 shows an example of a gear track 7 defining a track passage 701 for inserting the gear block 4.

[0081] In FIG. 3, the gear block has a gear unit 10 with corresponding gears corresponding to the gears in the gear track 7.

[0082] There is also a U-shape elastic unit 5 disposed at a bottom of the gear block 4 to perform the function mentioned above. A protruding I-shape structure is provided on the gear block 4 for the gear block 4 to move along the track passage 701 of the gear track 7.

[0083] The fork structure has multiple gear units 702 for keeping the gear block 4 unless an external force is applied to the gear block 604 to move with respect to the gear track 7.

[0084] In some embodiments, when the gear block moves along the gear track, the fork structure has an elastic deformation when the external force is applied to the gear block.

[0085] In FIG. 6, the fixing frame has two bars 651, 652 arranged in parallel for disposing the gear tracks 603, 6037.

[0086] The two bars 651, 652 and the telescopic levers 601, 602 form a rectangular structure.

[0087] In FIG. 8, the gear track has a limiter 608 for limiting a movement range of the gear block 603 with respect to the gear track 604.

[0088] In some embodiments, the fixing frame has two grooves 6013, 6023 for inserting protruding tongues into the two grooves to attach the main housing to the fixing frame.

[0089] FIG. 8 shows an example of protruding tongue 6071 to be inserted to the groove of the fixing frame 61.

[0090] In some embodiments, the main housing is movable along the two groove.

[0091] In FIG. 9, the installation platform includes two beams 802, 803 and a top ceiling 801.

[0092] Two ends 8041, 8042 of the fixing frame 804 are respectively fixed to the two beams 802, 803.

[0093] In some embodiments, the two telescopic levers are adjusted to change a spanning length to fit a distance between the two beams 802, 803, as illustrated in FIG. 6 and FIG. 7 mentioned above. In FIG. 8, the fixing frame 804 supports a main housing 805 that carries a light module and a ventilating fan.

[0094] In FIG. 10, a ceiling plate 821 has an installation opening 822 for fixing the fixing frame.

[0095] The ceiling plate 821 is attached to the ceiling after the fixing frame and the main housing are fixed to the ceiling plate 821.

[0096] In some embodiments, a lateral side of the fixing frame has installation holes to be fixed to a lateral side of a beam. This may be understood by removing the beam 803 in FIG. 9, which means only one side of the fixing frame is fixed to a beam 802.

[0097] The main housing is installed to the fixing frame after the fixing frame is fixed to the beam.

[0098] In FIG. 8, an ultraviolet light source 612 is placed in air tunnel for the air driven by the ventilating fan 605 to sterilize the air.

[0099] In some embodiments, the ventilating fan has a humidity sensor 6121 and automatically turns on the ventilating fan 605 when the humidity sensor 6121 detects a humidity larger than a predetermined threshold.

[0100] In some embodiments, the ventilating fan 605 creates an air flow to perform heat dissipation of the light module 606.

[0101] In some embodiments, the light module 606 emits a light signal when the ventilating fan 605 functions abnormally, e.g. a blinking light pattern.

[0102] FIG. 1 shows an example of a main housing 8 carrying a ventilating fan and a light module to be attached to a fixing frame 7 that is fixed on a ceiling plate 1 in advance.

[0103] FIG. 2 shows a fixing frame example. In FIG. 2, the fixing frame has a telescopic lever 2 as explained above.

[0104] There are protruding clips 3 disposed on the fixing frame to fix to an installation plate like the ceiling plate 1 illustrated in FIG. 1.

[0105] FIG. 3 shows a zoom-up view of the area A of FIG. 2. FIG. 3 is already explained in previous description.

[0106] FIG. 4 shows a gear block 4 with its bottom 6 to engage an installation platform.

[0107] FIG. 5 shows a gear track 7 to provide a movement of the gear block 4 that has a limiter 9.
