(1)High efficiency, economy of electricity and long service life:
The voltage, which the LED table lamp needs, is 6V. The table lamp takes four Size-A batteries. Its power consumption is less 80-90 percent than the same brightness incandescent lamp. Because the LED is the high brightness light emitting diode, it has no enormous change of resistance, which is caused, by the change of filament temperature in incandescent lamp. Thereby, the LED learning table lamp's service life can reach 10 thousand hours. This is 100 times as much as ordinary light bulb.
(2) No frequent twinkle---Protecting eyesight:
White light LED learning table lamp adopts direct current, and has no electromagnetic interference. White light LED can keep up a steady light, but without frequent twinkle. It is the best light source for protecting eyesight while studying or working.
(3) The light source that protects environment:
White light LED learning table lamp adopts LED as the light source. White light LED is a light-emitting semiconductor device that can transform electric signal to white light signal. LED is a kind of solid light source. Inside of that the PN junctions that possess light-emitting characteristic. While connecting with the mains, the PN junctions depend on a minority charge carriers to empty into them, and compound with them into cool white light. LED table lamp's illumination function is better than incandescent lamp. Compared with the traditional tungsten lamp, fluorescent lamp and economical lamp, the LED table lamp won't produce the Mercury vapour and traces of harmful elements. White light LED learning table lamp constructs the real green life.
(4) Safety and reliability:
White light LED learning table lamp uses LED as the light source, eliminating the traditional light bulb and light tube. Using LED table lamp will not have the accidents that the light bulb or light tube bursts. She is the best choice during the power out time or in the situation of no mains. She is the most reliable light source and signal lamp in wilderness.
(5) Definite illumination range:
Because white light LED learning table lamp adopts LED, its dispersion light effect in short distance is quite well, and is illumination range is definite. LED table lamp is suitable for short distance illumination, such as illumination for study or illumination for work.
