Energy-saving table lamp

Abstract

The invention relates to an energy-saving table lamp of which the luminescence is controlled through a light sensor and a single-chip microcomputer. The energy-saving table lamp is characterized in that a table lamp body structurally comprises a lighting tube, a communication conductor, a control circuit, an arc-surface lampshade, a base box, a bent adjustable hollow supporting rod, the light sensor, a power switch and a control key, wherein the control key is manufactured at one side of the front surface of the inclined table type base box; the light sensor is manufactured at the upper part of the other side of the front surface of the inclined table type base box, and the power switch is manufactured at the lower part of the other side of the front surface of the inclined table type basebox; the bent adjustable hollow supporting rod is vertically fixedly manufactured in the center of the rear side of the base box; the arc-surface lampshade is transversely fixedly manufactured on thetop part of the supporting rod; the lighting tube is clockwise manufactured in the lampshade; the communication conductor is manufactured in the arc-surface lampshade by passing through an inner chamber of the supporting rod in an electric communication manner, and thus the photoelectric information transmission and the automatic luminescence adjusting control functions can be realized. The energy-saving table lamp is simple in circuit principle, and safe and reliable in performances; and the table lamp which is manufactured based on a luminescence adjusting control circuit particularly has the advantages of being novel in structure, nice in appearance, and convenient to use and operate.

Description

Technical field: [0001] The invention relates to an energy-saving electronic adjustable lighting device which uses a light sensor and a single-chip microcomputer to control the brightness, in particular to an energy-saving desk lamp. technical background: [0002] There are mainly three types of existing energy-saving lamps with automatic dimming: one is the manual shifting type, which uses buttons to adjust the light intensity through manual control. The existing natural light intensity is effectively used, and the adjustment is not automatic; the second is the touch type, which sends a trigger pulse signal to the touch sensing end through the sensing electrode sheet, and adjusts and controls the light intensity and brightness through manual touch. The light mode is affected by the temperature of the touching hand to a certain extent, and cannot accurately and well meet the needs of dimming. It is often not used in some occasions that have strict requirements on light inten...

[0002] There are mainly three types of existing energy-saving lamps with automatic dimming: one is the manual shifting type, which uses buttons to adjust the light intensity through manual control. The existing natural light intensity is effectively used, and the adjustment is not automatic; the second is the touch type, which sends a trigger pulse signal to the touch sensing end through the sensing electrode sheet, and adjusts and controls the light intensity and brightness through manual touch. The light mode is affected by the temperature of the touching hand to a certain extent, and cannot accurately and well meet the needs of dimming. It is often not used in some occasions that have strict requirements on light intensity and brightness, such as hospitals, etc.

The third is the infrared induction type, which uses infrared sensing to adjust the brightness of energy-saving lamps and lanterns through the control circuit according to the intensity of natural light.

In recent years, a variety of lamps with electronic induction and automatic light intensity adjustment have appeared on the market. The illuminance after adjustment often cannot reach the ideal brightness required by users, and its energy-saving effect is not obvious. Therefore, this kind of desk lamp still exists. The adjustment is not sensitive, the energy saving effect is weak, the circuit principle is complicated, etc.
