Abstract

The invention provides a lifting indoor light emitting diode (LED) illumination device. The device has lifting structure and is used for adjusting the height of an LED lamp. The device comprises a lamp pole, a lamp holder and the LED lamp, wherein the lamp pole is arranged on the lamp holder; the device also comprises a lifter and a quadrangular lifting frame; the quadrangular lifting frame comprises an upper movable joint, a lower movable joint and two middle movable joints positioned between the upper movable joint and the lower movable joint; the lifter is fixed on the lamp pole and connected with the lower movable joint of the quadrangular lifting frame through a lifting pole; the upper movable joint of the quadrangular lifting frame is fixed on the lamp pole, and the LED lamp is fixed on the first middle movable joint; the lamp pole is provided with a chute, the lower movable joint is connected with the chute through a sliding body, and the lifting pole drives the sliding body to move up and down in the chute; and a spring spool is arranged on the lamp holder, a reflective tape is wound on the spring spool, the pull-out end of the tape is fixed on the second middle movable joint, and the reflective surface of the tape faces the LED lamp.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to an indoor LED lighting device. Background technique [0002] The current LED lamps have been widely used. Some low-power LEDs are usually used as materials for indoor desk lamps. Because LEDs are very power-saving, many LED desk lamps use a battery structure instead of completely relying on mains power supply for lighting, which brings great convenience to the movement of lamps. Existing LED desk lamp has inherited the main structure and shape of traditional incandescent lamp and energy-saving desk lamp, and they all do not have lifting structure. [0003] There are a large number of product types that use batteries in LED desk lamps. For such products, the power of the batteries will gradually decrease, followed by a reduction in lighting brightness. If the desk lamp keeps the same height all the time, it will inevitably cause the reduction of desktop illuminance, which will impair t...
