Lithium battery based illuminating apparatus

Abstract

The invention discloses a lithium battery based illuminating apparatus. The lithium battery based illuminating apparatus comprises a lithium battery; the charging input end of the lithium battery is connected with an external power supply through a TP 4056 chip based charging circuit; the power supply output end of the lithium battery is connected with an LED lamp set used for illuminating after passing through a change-over switch; the change-over switch is further connected with the LED lamp set through a timing circuit; and the power supply input end of the timing circuit is also connected with the power supply output end of the lithium battery. According to the lithium battery based illuminating apparatus, the lithium battery is small in volume, light in weight and long in service life, and the illuminating apparatus is multifunctional and more user-friendly in design. The lithium battery based illuminating apparatus is suitable for illuminating in various work and life environments.

Description

technical field [0001] The invention belongs to the field of lighting, and relates to a lighting device, in particular to a lighting device based on a lithium battery. Background technique [0002] Energy-saving desk lamps are widely used due to their advantages of low power consumption, power storage, and small size, especially for students' learning. There are many kinds of existing energy-saving desk lamps, and many problems also exist in the use process, wherein the most important problem is the power supply problem. Because most of the existing desk lamps are powered by storage batteries, although the storage batteries have the advantages of convenient use, low price, and high output power, they still have defects such as large volume, short service life, long charging time, and low charging efficiency; and some desk lamps The charging and discharging circuit design of the battery is very simple, which leads to poor stability of the voltage at both ends of the battery,...

AI Technical Summary

Problems solved by technology

[0004] Ordinary desk lamps do not have a timing function. Once the switch is turned on, the desk lamp will only be extinguished when the power stored in the power supply is used up, causing the user to fatigue their eyes for a long time without a reminder during use, which affects the user's vision;

[0005] Existing desk lamps can only be charged by a matching charger, and the charging method is single. When the desk lamp is out of power and there is no AC power supply, it is impossible to use other methods (such as a power bank) to charge the desk lamp;

[0006] The design height of existing desk lamps can only be used by one user. When two or more people use it at the same time, there will be insufficient brightness, which will adversely affect the user's vision
