There are a number of dimmable LED lights arrayed on the lower surface of the lampshade. This arrangement has multiple point light sources when in use, and these point light sources can be dimmed, so that each LED light can be adjusted when in use. Adjustment, set to different brightness, play a role in protecting the user's eyesight, the upper surface of the lampshade is provided with a touchpad, the lamp holder is provided with a control chip connected to the touchpad and the LED lamp, through such a setting , using the touch pad as a means of control input can conveniently and quickly receive the required information, and it is not necessary to adjust each lamp, which is convenient and quick to use.

Preferably, the shape of the touch panel corresponds to the shape of the distribution of the several LED lights. The shape of the touchpad corresponds to the shape of the distribution of LED lights, which is convenient for users to understand and operate.

Preferably, the touch panel adopts a four-wire resistive touch panel. The four-wire resistive touch panel has the characteristics of high resolution, high-speed transmission response, surface hardness treatment, reducing scratches, scratches and anti-chemical treatment, one-time calibration, high stability, and never drifting, and can fully receive touch when in use Signal, improve sensing speed and sensing accuracy.

Preferably, the switch includes a power switch and a dimming switch arranged on the rear side of the lamp holder. The practical operation is facilitated by setting separate power switch and dimmer switch.

As a preference, one side of the dimmer switch is provided with a linear adjustment indicator light and a radial adjustment indicator light. By being provided with a linear adjustment indicator light and a radial adjustment indicator light, the mode of the current light adjustment can be conveniently displayed, and it is convenient for the user to select an application.

Preferably, the lampshade and the lamp holder are hinged. The lampshade and the lamp stand are connected by hinges, so that the angle between the lampshade and the irradiation area can be adjusted freely, and different irradiation angles can be provided for users.

The beneficial effect of the utility model is that: by setting a number of LED lamps connected with control chips as light sources in an array, the illuminance can be adjusted freely in the irradiation area at the same time, protecting the user's eyesight, and using a touch panel as an input means to make the user The operation is simple and convenient.

Detailed ways

The technical solutions of the present utility model will be further specifically described below through specific embodiments in conjunction with the accompanying drawings.

Example:

A dimming table lamp (see attached drawing 1), including a lampshade 1, a touch panel 2, a lamp holder 3, a linear adjustment indicator light 4, a radial adjustment indicator light 5, a power cord 6, a dimmer switch 7, a power switch 8, Lamp holder 9, control chip 11 and some LED lamps 10 (see accompanying drawing 2); A power switch 8 is arranged in the middle of the rear side of the frame 3, and a dimmer switch 7 is arranged above the power switch 8, and a circular linear adjustment indicator light 4 and a circular radial adjustment indicator light 4 are respectively arranged on the left side of the dimmer switch 7 from top to bottom.
