Title:
LED DESK LAMP
Document Type and Number:
WIPO Patent Application WO/2018/086047
Kind Code:
A1
Abstract:
An LED desk lamp comprises a lamp holder (a), an LED light source (b), a control assembly (c), and a heat dissipation supporting arm (d). The heat dissipation supporting arm (d) and the lamp holder (a) are connected in a magnetically-attracted manner. A clamping opening (10) is formed in the top end portion of the heat dissipation supporting arm (d), and the LED light source (b) is clamped in the clamping opening (10). The control assembly (c) is mounted on the bottom end portion of the heat dissipation supporting arm (d). The LED light source (b) comprises an LED lamp plate (20), a spreadlight lens (21), a light shielding hood (22), a lamp bead (23) and a heat conduction block (24). An end surface of the heat conduction block (24) corresponding to the clamping opening (10) is a lamp plate fixing surface (e). The lamp plate fixing surface (e) is distributed by penetrates through the clamping opening (10), and the included angle between the lamp plate fixing surface (e) and a horizontal surface is an acute angle. The LED lamp plate (20) is fixed on the lamp plate fixing surface (e). The spreadlight lens (21) covers on the lamp bead (23). The light shielding hood (22) is mounted on the heat dissipation supporting arm (d) by means of the clamping opening (10). By means of the spreadlight lens (21) and the light shielding hood (22), a light illumination area can be effectively controlled, and the light illumination effect is improved. The heat dissipation effect of the desk lamp can be improved by using the heat dissipation supporting arm (d); and the heat dissipation supporting arm (d) and the lamp holder (a) are connected in a magnetically-attracted manner, which helps a user disassemble, assemble, move and carry the desk lamp.
