High quality solutions You can. Dimmer lamp dimming principle, is to use the thyristor (SCR) adjust the conduction Angle, change the alternating current (ac) electricity time to power a light bulb, change in order to achieve the average of the power supply voltage and current, adjust the effect of light intensity. 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.

Whether the LED desk lamp, luminous points: two guide plate and the patch?

LED lamps light source generally have patch light, into the light, and power source, there is also a surface light source. But more popular on the market at present is made of tiles and is by the desk lamp of light after diffusion of light guide plate, so the light will be soft not dazzling!
