Illumination device

Abstract

The invention relates to an illumination device. A main body structure of the illumination device comprises a light emitting lamp tube, a communication guide wire, a control circuit, a chambered lampshade, a base box, a bending adjustable inner hollow supporting rod, a photoreceptor, a light source switch and a control keyboard. The control keyboard is manufactured on one side of the front surface of the turn-table base box, and the photoreceptor is manufactured on the upper part on the other side and the light source switch is manufactured on the lower portion on the other side; the bending adjustable inner hollow supporting rod is fixedly manufactured at the center of the back side of the base box vertically; the chambered lampshade is fixedly manufactured on the top of the supporting rod transversely; the light-emitting lamp tube is manufactured in the lampshade consequently; the communication guide wire which electrically communicates with an inner cavity of the supporting rod is manufactured in the chambered lampshade and electrically communicates with the control circuit in the base box of the device in an information manner, so that photoelectric transmission and dimming automatic control function. The illumination device provided by the invention is simple in circuit principle and safe and reliable in performance, and in particular a table lamp tool formed based on a dimming control circuit has the advantages of being novel in structure, attractive in appearance, convenient to use and operate and the like.

Description

[0001] Technical field: [0002] The invention belongs to the field of lighting equipment, and relates to an energy-saving electronically adjustable lighting device, in particular to a lighting device. [0003] technical background: [0004] 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 ...

[0004] 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.
