What is the most appropriate lighting desk lamp to use at the writing desk when students do their homework at night

Choose incandescent lamps.

Children with lights, it is best to use two sources of light, the room ceiling lamps should be bright, it is best to use traditional incandescent lamps, close to the sun's mixed colors, brightness to about 45 watts for the best, so that the best effect on eye comfort.

Adding another table lamp light source on the desk. The placement of the desk lamp is also a good idea, in general, the right hand to hold the pen, the desk lamp is placed on the left side, the light should not be directly to the eyes, than the line of sight lower than some of the books, so that both the elimination of light shadows, to ensure the uniformity of the light, but also to improve the comfort of the eyes.

Non-frequency flash eye lamp:

Non-frequency flash eye lamp's basic principle of operation is to improve the low-frequency flash to high-frequency flashing, it uses the frequency electronic ballast, to accelerate the speed of the flashing, increased to thousands of times per second flashing or even tens of thousands of times per second, the speed of flashing more than the human eye's neural response speed, so in this kind of light learning, office, people will feel more eyes.

The phosphor in a few milliseconds under the afterglow, so there will be no so-called dark and light changes, no dark and light changes there is no strobe. In fact, in the frequency of tens of thousands of hertz and the amplitude of the stable signal drive, fluorescent lamps will continue to emit light "no strobe" phenomenon.

Most of the energy-saving desk lamps on the market now use high-frequency switching power supply technology, although reducing the strobe phenomenon, but if the circuit design is not appropriate, the desk lamp will produce a certain amount of electromagnetic radiation, which is detrimental to the health of the LED desk lamp is an exception to the exception of this type of desk lamp is a DC power supply, but its color temperature is not suitable for desk lamps, blue light, more unfavorable to the eyes, so we do not recommend the use of LED lamps! as a desk lamp.
