Multifunctional LED table lamp

Abstract

The invention discloses a multifunctional LED table lamp which comprises a base. A lamp holder is arranged on the base and provided with a rotary sleeve. A first adjusting rod is arranged on the rotary sleeve, and a hinge ball is arranged at the upper end of the first adjusting rod. A ball sleeve is arranged on the outer side of the hinge ball and connected with a second adjusting rod, and the second adjusting rod is connected with a lamp body through a rotary shaft. The lamp body comprises a lamp shell, sliding grooves are formed in the side face of the lamp shell in the vertical direction, and each sliding groove is in sliding connection with a light-emitting assembly. Each light-emitting assembly comprises a lampshade, an aluminum substrate, an LED lamp and a sliding assembly. An oxygenator is arranged in the lamp holder, USB charging jacks are arranged on the side face of the base, and a storage battery is further arranged in the base. A turn-off button, a sleep mode button and a study mode button are further arranged on the upper surface of the base. The multifunctional LED table lamp is simple in structure, easy to operate, adjustable in brightness, convenient to use, good in practicality and convenient to adjust, the service life of the LED lamp is prolonged, and the heat radiation effect is improved.

Description

technical field [0001] The invention relates to a lighting device, in particular to a multifunctional LED desk lamp. Background technique [0002] Light-emitting diodes are referred to as LEDs for short. Diodes made of compounds containing Gallium (Ga), Arsenic (As), Phosphorus (P), Nitrogen (N), etc. Visible light can be radiated when electrons and holes recombine, so they can be used to make light-emitting diodes. It is used as an indicator light in circuits and instruments, or as a text or number display. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Due to chemical properties, it is divided into organic light-emitting diode OLED and inorganic light-emitting diode LED. Light-emitting diodes can also be divided into ordinary monochromatic light-emitting diodes, high-brightness light-emitting diodes, ultra-high-brightness light-emitting diodes, colo...

AI Technical Summary

Problems solved by technology

However, it is found in its use that it cannot set the height and rotation according to the user's needs, and has a single function

Existing desk lamps can only play a lighting role. If the desk lamp can also supply oxygen, it will improve learning efficiency or sleep quality

With the development of science and technology, LED lamps have gradually replaced energy-saving lamps, but due to the large number of LED lamps with the same light source, the heat generated will be more, which will affect the service life of LED lamps, and most of the desk lamps in the prior art The light intensity per unit area is adjusted by adjusting the voltage. This electronic adjustment method also shortens the service life of the LED lamp to a certain extent. In the prior art, there is also a mechanical dimming method, but this method does not There are many and complicated lines. After a long time of use, the lines are prone to aging, and there are potential safety hazards.
