The utility model relates to a portable white light diode reading lamp, which has a lamp cap. The portable white light diode reading lamp is characterized in that one end of a twin-core copper conductor can be bent to be connected to the lamp cap; the other end is connected with a fixing clamp through a fixing piece; a flexible conductor with a plug is connected with an output hole of a power supply of a cell box. A DC regulated power supply is arranged; an output end of the DC regulated power supply is connected with a plug; a power supply switch is arranged on the cell box. The utility model has larger improvement on structure and efficacy, and has the advantages of high efficiency and energy saving. The photoelectric conversion efficiency is as high as 80 percents. The portable white light diode reading lamp is a solid rough service lamp; the lifetime is as long as 10 myriad hours and is 100 times than that of the existing incandescent lamps. Compared with the incandescent lamps with the same brightness, the electricity consumption is 1/10. The portable white light diode reading lamp can use four NO. 5 cells to directly supply power; under the condition of no obvious illumination intensity drop, the portable white light diode reading lamp can be continuously supplied with power as long as 90 hours. The lamp cap is connected with the fixing clamp through the bendable conductor, and is capable of separating with the cell box. Under the condition of not influencing other people's rest, the lamp cap can be fixed on a book through the fixing clamp; the move and the carrying are convenient.
