Abstract

The invention relates to an active self-luminescent LED lamp. The prior solar light emitting device is unlikely to work stably for long time. In order to solve the technical problem, the active self-luminescent Led lamp comprises an LED lamp assembly, a farad capacitor bank and a solar voltage-stabilizing charging power supply including a solar cell panel and a voltage-stabilizing diode, wherein the solar voltage-stabilizing charging power supply charges the farad capacitor bank through a diode D2. The active self-luminescent LED lamp is characterized in that the farad capacitor bank charges an electrolytic capacitor C3 through a current limiting device; and the electrolytic capacitor C3 releases a pulse current to the LED lamp through an oscillation circuit. The active self-luminescent LED lamp has the advantages of simple structure, low cost, and wide application, and can work continuously in rainy days and can provide sound-light alarm. The active self-luminescent LED lamp can be used for decorative lamps, automotive anti-collision lamp, obstacle alarm lamp, highway barrier lamp, pharos for ports, runway lights for airport and other various kinds of traffic caution lights.

Description

technical field [0001] The invention relates to an LED light emitting device, in particular to an active self-luminous LED light. Background technique [0002] Existing solar LED light-emitting devices use solar cells to charge the storage battery. Since the storage capacity of the battery will rapidly decay after charging and discharging for a certain number of times, the life of this light-emitting device is limited. When users use it, they often fall into the embarrassing situation of saving energy but not saving money. [0003] The Chinese invention patent application with publication date of May 24, 2006, publication number CN 177585A, titled "Power System of Farad Capacitor Electric Vehicle Capable of Utilizing Solar Energy" proposes to use Farad capacitor as the main energy storage component, which can effectively extend the solar energy. The charging and discharging times of the charging and discharging device. However, farad capacitors have the characteristics of ...
