Description

A desk lamp with no shadow control light

technical field

The invention relates to the technical field of desk lamps, in particular to a desk lamp with no shadows to control lighting.

Background technique

Desk lamps are an indispensable item in daily life, and when the desk lamps control the light, most of them emit light through the transistors of the desk lamps. When the transistors control the brightness of the light source, they control the power supply of the desk lamps connected to the desk lamps. To control the brightness of the table lamp, in the control of the power, the transistor appears bright and dim for a while, which leads to damage to the transistor in the table lamp, which is not easy to use for a long time, and the table lamp in daily life is prone to shadow surfaces when it is used. Insufficient illumination of the light source during use will result in experience effects during use.

The working principle in the comparison document CN 108112117 A is to control the brightness of the light source to make it possible to automatically control the brightness of the light source, but such drawbacks are as mentioned above, the brightness of the lamp is between dimming and brightening. Adjustment will cause the lamp to speed up the scrap rate.

The principle of A in the comparison document CN 107461616 A is to refract the whole body, so that the emitted surfaces are concentrated in one place to form a shadowless light spot, but this type of light spot is not used in household table lamps, and household table lamps are mainly aimed at the appearance of the top of the lamps.
