LED rechargeable lamps learning how many watts?
From my experience, using LED lights 1 w to 3 w. Range so big because the LED chip quality is uneven, see what is the quality of.
Regular household study led desk lamp 5-6 w, that is using high power led, led rechargeable table lamp is the 20-30 extremely small straw hat head led luminous efficiency, power consumption province, but also greatly droop, life is not long, be in commonly 2 w or so, the new is very bright, after half a year can significantly dimmed, up to 2 years scrap (even if the led hasn't completely extinguished, but the battery is broken, can't charge electricity)
Visual lighting environment is very important, family, speaking, reading and writing assignments at home to read and write operations is one of the most important learning visual lighting environment, specifically is to learn the quality of the lamp quality. Learning is a great variety of lamps on the market, there is the lamp that shield an eye, energy-saving lamps, incandescent lamp and LED lamp, etc. Discriminant learning quality of the quality of the lamp, if the light color of white, or light color dim, dazzling the desk lamp of illumination is not standard, are unfavorable for family learning source, because then there will be a bad influence on the vision of development.
Generally 5-10 w. 1. LED desk lamp is with LED (Light Emitting Diode) the desk lamp of the light-emitting Diode as Light source, LED is a solid-state semiconductor devices, it can be directly put DianZhuan into Light. Is the third generation after the incandescent lamp, fluorescent lamp lighting technology, has the characteristics of energy saving, environmental protection, safe and reliable, solid-state lighting is favored by the industry in the next decade to replace traditional lighting appliance potential new light source, represents the future of lighting technology.
