The supporting bracket has a vertical part vertically fixed on the base and a horizontal part extending horizontally from an upper end of the vertical part. The horizontal part defines an opening therein. The heat sink is placed on a top surface of the supporting bracket and located over the opening. The LED module is received in the opening of the horizontal part. ## Claims ### Claim 1 An LED reading lamp comprising: a base; a supporting bracket fixed on the base and defining an opening therein; a heat sink mounted on the supporting bracket and located over the opening; and an LED module accommodated in the opening and attached to a bottom of the heat sink. ### Claim 2 (depends on 1) The LED reading lamp of claim 1, wherein the heat sink is placed on an outer face of the supporting bracket. ### Claim 3 (depends on 2) The LED reading lamp of claim 2, wherein the heat sink is in thermal conducting relationship with a plurality of protruding strips formed on the outer face of the supporting bracket. ### Claim 4 (depends on 2) The LED reading lamp of claim 2, wherein a flatted supporting part surrounding the opening is formed on the outer face of the supporting bracket and engages with an edge portion of the bottom of the heat sink to secure the heat sink thereon. ### Claim 5 (depends on 4) The LED reading lamp of claim 4, wherein the heat sink comprises a base plate having a bottom surface engaging with the supporting part of the supporting bracket and a plurality of fins formed on a top surface of the heat sink. ### Claim 6 (depends on 5) The LED reading lamp of claim 5, wherein the opening and the base plate are elongated and arranged along a lengthwise direction of the supporting bracket, the base plate is located over the opening with a central part of the bottom surface corresponding to the opening. ### Claim 7 (depends on 5) The LED reading lamp of claim 5, wherein the protruding strips on the outer face of the supporting bracket and the fins of the heat sink are parallel to two opposite lateral sides of the supporting bracket and arranged along a lengthwise direction of the supporting bracket. ### Claim 8 (depends on 1) The LED reading lamp of claim 1, wherein the supporting bracket is bent into an L-shape and comprises a vertical part standing on the base and a horizontal part extending horizontally from an upper end of the vertical part, the opening being defined in the horizontal part. ### Claim 9 (depends on 1) The LED reading lamp of claim 1, wherein a smooth corner is formed at a joint of the vertical part and the horizontal part of the supporting bracket. ### Claim 10 (depends on 1) The LED reading lamp of claim 1, further comprising a lamp cover which is made of transparent or semi-transparent material, the lamp cover covers an inner face of the supporting bracket. ### Claim 11 (depends on 10) The LED reading lamp of claim 10, wherein two flatted engaging flanges are formed at two lateral portions of lamp cover and are engaged with two corresponding lateral portions of the inner face of the supporting bracket, while a middle portion of the lamp cover connecting two facing inner edges of the two engaging flanges plumps up to from a covering space between the lamp cover and the supporting bracket. ### Claim 12 (depends on 11) The LED reading lamp of claim 11, further comprising two clipping members attached to opposite lateral sides of the lamp cover and the supporting bracket to fasten the lamp cover and the supporting bracket together. ### Claim 13 (depends on 12) The LED reading lamp of claim 12, wherein each clipping member comprises a connecting strip attached to corresponding lateral sides of the supporting bracket and the lamp cover at a same side and two clipping flanges sandwiching therebetween lateral portions of the supporting bracket and the engaging flange of the lamp cover near the corresponding lateral sides. ### Claim 14 (depends on 1) The LED reading lamp of claim 1, further comprising an accessional member placed on the base and located at an outer side of the supporting bracket, the accessional member comprising a receiving box for receiving electronic components therein and two semi-cylindrical pencil vases formed at two opposite lateral sides of the receiving box. ### Claim 15 An LED reading lamp comprising: a base; a supporting bracket comprising a vertical part vertically fixed on the base and a horizontal part extending horizontally from an upper end of the vertical part, the horizontal part defining an opening therein; and a heat sink placed on a top surface of the supporting bracket and located over the opening; and an LED module mounted on a bottom surface of the heat sink and received in the opening of the horizontal part. ### Claim 16 (depends on 15) The LED reading lamp of claim 15, wherein the heat sink comprises a base plate to which the LED module is attached and a plurality of fins formed on a top surface of the base plate, the base plate being in thermal conducting relationship with a plurality of protruding strips formed on the outer face of the supporting bracket. ### Claim 17 (depends on 16) The LED reading lamp of claim 16, wherein a flatted supporting part surrounding the opening is formed on the outer face of the supporting bracket and engages with an edge portion of a bottom surface of the base plate to secure the heat sink thereon. ### Claim 18 (depends on 15) The LED reading lamp of claim 15, further comprising a lamp cover which is made of transparent or semi-transparent material and covers an inner face of the supporting bracket. ### Claim 19 (depends on 18) The LED reading lamp of claim 18, wherein two flatted engaging flanges are formed at two lateral portions of lamp cover and are engaged with two lateral portions of the inner face of the supporting bracket, while a middle portion of the lamp cover connecting two facing inner edges of the two engaging flanges plumps up to form a covering space between the lamp cover and the supporting bracket. ### Claim 20 (depends on 15) The LED reading lamp of claim 15, further comprising two clipping members attached to opposite lateral sides of the lamp cover, each clipping member having two spaced clipping flanges sandwiching corresponding lateral portions of the supporting bracket and the lamp cover therebetween to secure the lamp cover and the supporting bracket together.
