Patent ID: 7375968

Claim:
An improved desk lamp, comprising: a heat dissipating housing, a space being provided within the heat dissipating housing and a window being provided at an upper portion on an inner side of the heat dissipating housing; a heat dissipating module, held in the space provided within the heat dissipating housing and in contact with an inner wall of the heat dissipating housing; the heat dissipating module includes a heat conducting plate, at least a heat conducting tube and at least a heat dissipating fin, and wherein the heat conducting plate is connected with the heat dissipating fin by the heat conducting tube and the heat conducting plate is aligned with the window so that a light unit may be disposed on the heat conducting plate of the heat dissipating module, and wherein the heat dissipating fin is in contact with the heat dissipating housing; the light unit, disposed on the heat conducting plate of the heat dissipating module, is aligned with the window so that the light radiating from the light unit may go through the window to provide illumination; a switch, able be used to turn on and turn off the light unit, wherein the heat generated by the light unit may be absorbed by the heat dissipating module and then be transmitted to the heat dissipating housing so that the heat may be quickly dissipated into the ambient surrounding by the heat dissipating housing.
