Abstract

The invention relates to the field of light-emitting diode (LED) illuminating lamps, in particular to an LED ground lamp with a self protection function. The LED ground lamp comprises a lamp, an LED driving power supply and LED lamp beads packaged in the lamp. The LED ground lamp is characterized by also comprising at least one self-restoring fuse tube which is packaged in the lamp, forms an electric loop with the LED lamp beads and the LED driving power supply and is high in resistance when the current or the temperature is abnormal; and the plurality of LED lamp beads can be connected in series or in parallel, and can be connected in series and in parallel, or can be connected crossly. The LED ground lamp has the advantages that: when the current in a circuit is overhigh or the temperature in the LED lamp is overhigh, the resistance of the self-restoring fuse tube is very high, so the current of a main circuit or sub-circuits is limited, and the LED lamp beads of the LED ground lamp are prevented from being damaged; the operation of the LED ground lamp is kept and the LED ground lamp is effectively protected by limiting the current of a part of sub-circuits but not affecting other sub-circuits.

Description

[0001] technical field [0002] The present invention relates to the field of LED lighting lamps, in particular to an LED floor lamp with self-protection function. Background technique [0003] LED ground lights are widely used in the lighting of lawns, roads and landscapes. LED ground lights generally have an upper limit for voltage and current, but often due to various reasons in use, the current increases and the voltage increases, resulting in damage to the LED ground light. [0004] Self-recovery fuse, also known as polymer positive temperature thermistor PTC, is composed of polymer and conductive particles. After special processing, the conductive particles form a chain-like conductive path in the polymer. When the normal current passes (or the element is at normal ambient temperature), the PTC self-recovery fuse is in a low-resistance state; The heat generated rapidly expands the polymer, which cuts off the conductive path formed by the conductive particles, and the ...
