Description

一种环保智能护眼台灯An environmentally friendly and intelligent eye-protecting desk lamp

技术领域 technical field

本实用新型属于照明灯具领域,涉及一种由太阳能供电的新型LED护眼台灯,特别是一种智能化控制的护眼灯。 The utility model belongs to the field of lighting fixtures, and relates to a novel LED eye-protecting desk lamp powered by solar energy, in particular to an intelligently controlled eye-protecting lamp.

背景技术 Background technique

早期市场上的台灯一般采用白炽灯做光源,但是白炽灯发光带黄色,发热温度高,热蒸发快,寿命较短,发光效率低,不利于节能。之后生产了荧光灯,但是荧光灯是玻璃制品,而且含有汞,破碎后对身体有害,节能效率也不高,荧光灯如果频繁的启动或关断,灯丝就会发黑很快的坏掉。白炽灯和荧光灯都有频闪和电磁辐射,会给使用者带来一定的伤害,现在市场上大多数“护眼”灯没有频闪,只是采用电感镇流器使荧光灯的频率将低频闪调成高频闪,使人眼感受不到频闪的不适,但是不会彻底消除频闪。 Early desk lamps on the market generally used incandescent lamps as light sources, but incandescent lamps emit yellowish light, high heating temperature, fast heat evaporation, short life, and low luminous efficiency, which is not conducive to energy saving. Later, fluorescent lamps were produced, but fluorescent lamps are made of glass and contain mercury, which is harmful to the body after being broken, and the energy-saving efficiency is not high. If fluorescent lamps are frequently turned on or off, the filament will turn black and quickly break down. Both incandescent and fluorescent lamps have stroboscopic and electromagnetic radiation, which will cause certain harm to users. Most "eye protection" lamps on the market do not have stroboscopic, but use magnetic ballasts to adjust the frequency of fluorescent lamps to low-frequency flicker. Into high-frequency flicker, so that the human eye does not feel the discomfort of stroboscopic, but it will not completely eliminate stroboscopic.

另外,一般的台灯都是手动模式调控,不能根据环境亮度随时调节光强度,而且如果忘记关灯会造成能源的极大浪费,也会损害灯具的寿命。而到了晚上人们又需要摸黑去开灯,非常不方便。 In addition, ordinary desk lamps are controlled in manual mode, and the light intensity cannot be adjusted at any time according to the brightness of the environment. Moreover, if you forget to turn off the lamp, it will cause a great waste of energy and damage the life of the lamp. And at night people need to turn on the lights in the dark, which is very inconvenient.
