Many people don't know what kind of lamp is the eye protection table lamp in life. In fact, the eye protection table lamp is a kind of lamp that can prevent children from learning myopia. Reading for a long time during use will not irritate the eyes, so parents must understand the function of the eye protection table lamp when purchasing the lamps. Please write down the details of the types of eye protection lamps . Type of eye protection table lamp First, electric eye protection table lamp Ordinary incandescent lamps and halogen lamps have a continuous spectrum, which is the light closest to the natural spectrum, so it is also a kind of eye protection table lamp, and because the alternating current first heats the filament, the filament heats up and then emits light, and the filament has heat capacity, so the power source When changing, the filament is still hot, and the degree of light and dark changes is not as pronounced as fluorescent lamps (ie, fluorescent lamps). However, due to the low energy efficiency of incandescent lamps, it has gradually withdrawn from the market. Second, high frequency eye protection table lamp The eye-protection table lamp fluorescent lamp and energy-saving lamp use a high-frequency electronic ballast, the strobe can be as high as 30-50 kHz, and the phosphor has a "afterglow effect", so the human eye does not perceive the stroboscopic. Eye protection table lamp Third, LED eye protection table lamp There are three kinds of color temperature of LED eye protection table lamp : warm white (a little yellowish, color temperature is 2700-3000k), white (color temperature is 5000-7000k), and cool white (color temperature is 8000-12000k), cool white LED lights will be compared The glare, LED eye-protection table lamp is mainly suitable for occasions that require large-scale landscape illumination and does not require high light quality. It is not suitable for use in environments requiring high eye use, because LEDs contain a large proportion of blue light components and are easy to damage the eyes. In addition, the small lamp bead of the LED lamp has a problem of attenuation rate, and is relatively susceptible to loss, which may cause the desk lamp to be scrapped. Moreover, LEDs and the like have a small illumination area and a narrow chromatogram, which is a monochromatic light source and affects the optic nerve. However, the electronic original cost of the LED desk lamp is low, and the price of the desk lamp is relatively cheap. table lamp Fourth, DC fluorescent eye protection table lamp DC fluorescent eye protection table lamp uses DC ballast to convert AC power into DC power with voltage and current. Fluorescent eye protection table lamp can achieve no stroboscopic light, soft light, continuous uniformity, can alleviate visual fatigue, and solve the magnetic ballast. Fluorescent lamp strobe problem, in addition, because the DC technology does not have any AC fluctuations, the eye protection desk lamp also avoids the electromagnetic interference signal caused by the high frequency electronic ballast. However, the DC fluorescent lamp has a large process and high cost, and has not yet been popularized. The above is the type of eye protection table lamp that you can share with you. I hope to help you. If you want to know more about eye protection desk lamps, please continue to pay attention to the net. Get a quote for 10 seconds and get four sets of design solutions for free.
