LED grass insertion lamp for alternating current and low-voltage direct current

Abstract

The invention discloses an LED grass insertion lamp for alternating current and low-voltage direct current. The LED grass insertion lamp comprises a driving power source and an LED lamp body with an LED light source plate. The driving power source is composed of a detection control circuit, a high-voltage driving circuit, a low-voltage driving circuit, a first control switch circuit and a second control switch circuit. The alternating current and the low-voltage direct current are output in three ways and connected with the input end of the detection control circuit, the input end of the high-voltage driving circuit and the input end of the low-voltage driving circuit respectively, the first output end of the detection control circuit is connected with the input end of the first control switch circuit, the second output end of the detection control circuit is connected with the input end of the second control switch circuit, the output end of the first control switch circuit is connected with the input end of the high-voltage driving circuit, the output end of the second control switch circuit is connected with the input end of the low-voltage driving circuit, and the output end ofthe high-voltage driving circuit and the output end of the low-voltage driving circuit are connected with the LED light source plate respectively. The LED grass insertion lamp has the advantages thatthe alternating current or the low-voltage direct current can be selected for power supply, and the requirements of the two different voltages of alternating current and direct current can be met.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED grass plug lamp for dual use of commercial power and low-voltage direct current. Background technique [0002] LED grass plug lamp is a lamp for outdoor landscape lighting, which can be used in home gardens, parks, squares and other places. LED grass plug lights can generally be installed directly on the ground or on the surrounding walls. By adjusting the position of the lights, the light from the light source in the lights can be directly irradiated on the landscape. [0003] Existing LED grass plug lamps usually can only be powered by mains or low-voltage direct current alone. This kind of LED grass plug lamp has the following problems: 1) For LED grass plug lights that can only be powered by mains power alone, in Some landscape places without pre-embedded mains facilities need to be wired and powered from other places. During the wiring process, due to the long lines and high voltage of...

Problems solved by technology

[0003] Existing LED grass plug lamps usually can only be powered by mains or low-voltage direct current alone. This kind of LED grass plug lamp has the following problems: 1) For LED grass plug lights that can only be powered by mains power alone, in Some landscape places without pre-buried mains facilities need to be wired and powered from other places. During the wiring process, due to the long lines and high voltage of the mains, there are potential safety hazards; 2) For only low-voltage direct current power supply The LED grass plug lamp needs an external low-voltage power supply device, and in the landscape places that can be directly powered by the mains, the mains lighting cannot be used
