An opening is formed on a lateral wall of the housing. The plate is detachably connected to the housing, so as to cover the opening. The plate includes a first side, a first guiding slot formed on the first side, a second side opposite the first side, a second guiding slot formed on the second side, and a bottom side adjacent to a bottom plate of the housing. At least a portion of the lateral wall is accommodated in the first and second guiding slots. The wireless coil is disposed in the housing and adjacent to the plate. The electronic member is disposed in the housing and electrically connected to the wireless coil. The housing and the plate are respectively made of metal and non-metal materials. ## Claims ### Claim 1 A light-emitting diode driver, comprising: a housing, comprising a lateral wall and a bottom plate, wherein the lateral wall is connected to the bottom plate, and an opening is formed on the lateral wall; a plate, detachably connected to the housing and covering the opening, comprising: a first side; a first guiding slot, formed on the first side, wherein a portion of the lateral wall is accommodated in the first guiding slot when the plate is connected to the housing; a second side, opposite the first side; a second guiding slot, formed on the second side, wherein a portion of the lateral wall is accommodated in the second guiding slot when the plate is connected to the housing; and a bottom side, adjacent to the bottom plate; a wireless coil, disposed in the housing and adjacent to the plate; and at least one electronic member, disposed in the housing and electrically connected to the wireless coil, wherein the housing is made of metal materials, and the plate is made of non-metal materials. ### Claim 2 (depends on 1) The light-emitting diode driver as claimed in claim 1, wherein the plate further comprises a third guiding slot foil ied on the bottom side, and a portion of the lateral wall is accommodated in the third guiding slot when the plate is connected to the housing. ### Claim 3 (depends on 2) The light-emitting diode driver as claimed in claim 2, wherein the third guiding slot is communicated with the first guiding slot and the second guiding slot. ### Claim 4 (depends on 1) The light-emitting diode driver as claimed in claim 1, wherein the light-emitting diode driver further comprises a cover detachably connected to the lateral wall of the housing, wherein the wireless coil and the electronic member are disposed between the cover and the bottom plate. ### Claim 5 (depends on 4) The light-emitting diode driver as claimed in claim 4, wherein the cover comprises an extending portion extended toward the bottom plate, and the plate is disposed between the extending portion and the wireless coil. ### Claim 6 (depends on 1) The light-emitting diode driver as claimed in claim 1, wherein the light-emitting diode driver further comprises a wire, and the plate further comprises a through hole, wherein the wire passes through the through hole and connects to the wireless coil or the electronic member. ### Claim 7 (depends on 6) The light-emitting diode driver as claimed in claim 6, wherein the light-emitting diode driver further comprises a cover detachably connected to the lateral wall of the housing, and the cover comprises an extending portion extended toward the bottom plate, wherein the extending portion has a round corner adjacent to the wire. ### Claim 8 (depends on 1) The light-emitting diode driver as claimed in claim 1, wherein the opening and the lateral wall have a cross-sectional area, and the area of the opening occupies 80% of the cross-sectional area. ### Claim 9 (depends on 8) The light-emitting diode driver as claimed in claim 8, wherein the dimensions of the plate are substantially the same as the dimensions of the opening. ### Claim 10 (depends on 1) The light-emitting diode driver as claimed in claim 1, wherein the lateral wall has a first end and a second end, the first end is connected to the bottom plate, and the second end is opposite the first end, wherein the distance between the bottom side and the second end is less than ⅙ of the distance between the first end and the second end. ### Claim 11 (depends on 1) The light-emitting diode driver as claimed in claim 1, wherein the lateral wall has a first end and a second end, the first end is connected to the bottom plate, the second end is opposite the first end, and the plate does not protrude from the second end.
