The sheet type led light source cooperate the scattering sheet of special optical design can make the LED desk lamp to go out light effect more good; Preferably, said sheet type led light source is flexible base, board or does not have substrate foil formula led array light source that its size and the size position of scattering sheet relatively meet the shadowless lamp design.
Preferably, said switch is the touch panel switch; But the choice structure of touch panel switch is wider, can electronic touch formula IC be installed in lamp interior, the touch place is set on light fixture, forms control loop between the electrode slice of electronic touch formula IC and touch place; When human body touches the electrode slice of induction, touch signal produces a pulse signal by Rectified alternating current and is sent to the touch sensible end, and then the touch sensible end can send a start pulse signal, just can control and turn on light; As touch once again, touch signal can produce a pulse signal by Rectified alternating current again and be sent to the touch sensible end, and this moment, the touch sensible end will stop to send start pulse signal, and when the alternating current zero passage, lamp extinguishes naturally.
Preferably, said LED power supply is the constant-current decompression power supply; Make the LED desk lamp in use leaky can not occur, guarantee safe in utilization.
As a kind of design; The lead and the LED power supply that connect between sheet type led light source, LED power supply and the switch all design in lamp interior; Avoid contacting of cable and people or other price, guarantee the stable and safety of use of whole LED desk lamp, take into account the attractive in appearance of whole LED desk lamp simultaneously.Certainly, can also trough be set, be convenient to the cabling of external cable, guarantee that all parts can both sink to lamp interior in the bottom of LED desk lamp.
Preferably, the material of said light fixture is PC material, acrylic material, ABS material or metal material, and transparent material, translucent material, nontransparent material all can.
Preferably, said scattering sheet is made by the transparent PC material of light diffusion PC material, frosted processing, optically coated transparent PC material; Scattering sheet can make the light of sheet type led light source distribute more equably.
Beneficial effect: a kind of integral type that the utility model provides does not have heat sink and radiator LED desk lamp; Adopt the sheet type led light source, the existing desk lamp of comparing is from optics, electricity, calorifics with mechanically all optimize; Under the prerequisite that realizes trouble free service; The life-span of led light source is improved greatly, and its configuration design space is bigger simultaneously, is fit to modern desk lamp design requirement.
