The LED lamp can change the light bulb

LED desk lamp is small current is energy-saving lamp, lamp power current too big, want to use have to change very troublesome, some parts to replace. The LED desk lamp is to protect the eyes and the light bulb is 50 hz frequency of eye fatigue.

LED dual-mode folding desk lamp on external what meaning be

Dual mode, it is to point to can use ac and dc two modes of desk lamp power supply. Both external and internal, and ultimately to the LED lamp bead above, must be dc power supply.

Why do some led desk lamp is white light, have a plenty of take a bit of blue?

Cold white: very high proportion of blue light, the color of the slant blue, so the color of the light in the eye seems to give people a feeling of "cold", so called cold white. Cold white the sense that gives a person dazzling, used for decoration and local lighting.

General how long LED desk lamp charging full of learning

Depending on the quality of the products performance difference is very big in general is roughly in 3 ~ 5 hours, and the influence on charging the battery life is over charge and discharge, so it is best not to wait until there was no electricity charge when using don't charging time is too long, in use roughly estimate the time almost no electrical charge

Desk lamp with led bulbs or incandescent lamps good

Incandescent lamp: low light efficiency, high energy consumption), ac drive No blue light damage, high color rendering index

The maintenance of the charging table lamp

Energy-saving lamps, LED lights, there are the power transformation, all need power supply of alternating current into direct current (dc) first, and then into a high frequency ac (CFL) or dc constant current (leds) to drive a light emitting part.
