DETAILED DESCRIPTION

[0157] In some embodiments, a downlight apparatus includes a light source 6014, a driver box 6001, a light housing 6007 and a stop unit 6015.

[0158] The driver box 6001 is used for storing a driver 6019.

[0159] The driver 6019 is connected to an external power source to generate a driving current to the light source 6014. The driver 6019 may include a rectifier, a transformer, a filter, a current source, a protection circuit and other components.

[0160] The driver box 6001 has a wall 6025 with an installation escape 6002.

[0161] The light housing 6007 has a light holder 6005 and a rim 6006.

[0162] The light source 6014 is stored in the light holder 6005.

[0163] The rim 6006 defines a light opening 6026 for a light of the light source 6014 to escape.

[0164] The stop unit 6015 is fixed to the installation escape 6002.

[0165] The stop unit 6015 has a switch holder 6010 and a wire holder 6011.

[0166] A manual switch 6008 is placed in the switch holder 6010 and an enlarged wire head 6012 of an power wire 6013 is placed in the wire holder 6011.

[0167] An operation part 6009 of the manual switch 6008 is exposed outside the driver box 6001.

[0168] The manual switch 6008 is connected to the driver 6019 for adjusting a setting of the driver 6019.

[0169] In some embodiments, the installation escape 6002 is a first U-shape concave on the wall of the driver box 6001. The stop unit 6015 is inserted into the first U-shape concave along two lateral edges of the first U-shape concave.

[0170] FIG. 74 shows such an example. In FIG. 74, the driver box 972 has a first U-shape concave 9713 for inserting the stop unit 9721.

[0171] In FIG. 78, the stop unit has two lateral grooves 975 as tracks for sliding the two lateral edges of the first U-shape concave to attach the stop unit to the driver box.

[0172] In FIG. 78, a front plate 9792 and a back plate 9791 of the stop unit form the two lateral grooves 975.

[0173] The front plate 9792 is closer to outside of the driver box than the back plate 9791.

[0174] The back plate 9791 has a larger diameter than the front plate 9792 to prevent water to move in the drive box.

[0175] In some embodiments, the switch holder is a second concave U-shape concave of the stop unit.

[0176] The manual switch is inserted and fixed to the second U-shape concave 973.

[0177] In some embodiments, the switch holder has two switch grooves 976 for inserting and fixing two lateral edges of the manual switch.

[0178] In some embodiments, the switch holder has a front space 97303 and a back space 97301.

[0179] The back space 97301 is used for storing a switch board. For example, a manual switch is a switch board mounted with a lever or a slider.

[0180] The front space 97301 is used for storing an operation unit of the manual switch.

[0181] In some embodiments, the wire holder is a third U-shape concave 974 of the stop unit.

[0182] The enlarged wire head is inserted and fixed to the third U-shape concave.

[0183] In FIG. 87, the downlight apparatus may also include a electrode socket 6003.

[0184] The light source includes a light source plate 6031 mounted with LED modules 6032.

[0185] The light source plate 6031 has a plate hole for inserting and fixing the electrode socket 6003.

[0186] In FIG. 28, a plate hole 9991 is used inserting the electrode socket 9992.

[0187] In FIG. 25, the electrode socket 9912 has an insulation base 991 with a first electrode groove and a second electrode groove 9910.

[0188] The insulation base defines a first electrode hole and second electrode hole 9911.

[0189] In FIG. 26, the electrode socket has a first metal unit and a second metal unit 9922. The first metal unit and the second metal unit 9922 respectively have elastic receivers 99212 for inserting a driver electrode electrically connecting to the driver.

[0190] In some embodiments, the first metal unit and the second metal unit 9922 respectively have an elongated bar 99227 respectively extending along the first electrode groove and the second electrode groove.

[0191] The first metal unit and the second metal unit respectively have a contact end 99228 for electrically connecting to the LED modules on the light source plate.

[0192] In some embodiments, the first electrode groove and the second electrode groove are above a top surface of the light source plate, as illustrated in FIG. 28.

[0193] In some embodiments, the contact ends extend along an edge of the insulation to be welded to light source electrodes of the light source plate.

[0194] In FIG. 26, electrode receiver 99212 has an elastic clip 99211 for inserting the driver electrode.

[0195] In some embodiments, the elastic clip 99211 is a reverse hook with a smaller force on attaching the driver electrode to the electrode receiver than detaching the driver electrode off the electrode receiver In some embodiments, any metal part of the electrode socket and the driver electrode is kept longer than 4 mm from any metal part of the light source plate.

[0196] In some embodiments, any metal part of the electrode socket and the driver electrode is kept longer than 1 mm from any metal part of the light source plate.

[0197] For example, the L1 and L2 distance are longer than 4 mm or 1 mm depending on whether the downlight device is used in water environment or not.

[0198] In some embodiments, the insulation base has a light reflective layer for redirecting the light of the light source. For example, a surface of the insulation base is painted with white paint so as to increase a light reflective rate, particularly when the insulation base is protruding above the surface for mounting the LED modules, which may cause shadow or undesired effect.

[0199] In some embodiments, the electrode socket has an antenna socket 6041 for plugging an antenna. For example, an antenna is plugged to the antenna socket 6041.

[0200] In FIG. 25, the insulation base has a middle protrusion 99101 separating the first electrode groove and the second electrode groove.
