The lawn lamp are decorative lighting that can be used in the green belts of parks, garden villas, square greening, and other places. They have the characteristics of easy installation and strong decoration. Lawn lights can provide necessary lighting and convenience of life, and increase residents' sense of security. It can also highlight the highlights of the city and interpret the bright style. There are six categories of European lawn lights, modern lawn lights, classical lawn lights, anti-theft lawn lights, landscape lawn lights, and LED lawn lights.
There are two types of common faults of lawn lights: one is high resistance fault; the other is low resistance fault. There are four reasons for the failure:
1. Poor construction quality
Faults caused by construction quality account for a larger proportion. Main manifestations: First, the depth of the cable trench is not enough, and the construction of sand-covered bricks is not carried out according to the standard; the second is that the production and installation of the aisle pipe does not meet the requirements, and the two ends are not made according to the standard. The third is when laying cables Dragging on the ground; Fourth, the embedded pipe of the foundation is not constructed according to the standard requirements, mainly because the embedded pipe is too thin, plus a certain degree of curvature, it is quite difficult to pass the cable, and there is a "dead bend" at the bottom of the foundation; It is because the thickness of the wire nose crimping and insulation wrapping is not enough, it will short circuit after long time operation.
2. The materials are not good enough
Judging from the failure situation handled in recent years, low material quality is also a big factor. The main performance is: the wire contains less aluminum, the wire is relatively hard, and the insulation layer is thin. This situation has become more common in recent years.
3. The quality of supporting projects is not too hard
Lawn light cables are generally laid on the green belt. The construction quality of the sidewalk is poor, and the ground sinks, which causes the cable to be deformed by force, resulting in cable armoring. Especially in the northeast region, which is located in the high cold zone, the winter comes, so that the cables and the soil form a whole. Once the ground subsides, it will be strained at the bottom of the lawn lamp foundation, and in the summer when there is a lot of rain, it will burn at the foundation root.
4. Unreasonable design
One aspect is overload operation. With the continuous development of urban construction, lawn lights continue to expand. When new lawn lights are built, they are often close to which lawn lamp is connected to which circuit. In addition, the advertising industry has developed rapidly in recent years, and the advertising load is also connected to the lawn accordingly. On the lamp, the load of the lawn lamp is too large, the cable is overheated, the wire nose is overheated, the insulation is reduced, and the grounding short circuit occurs; on the other hand, the pole design only considers the pole’s own situation and ignores the space of the cable head. After the cable heads are wrapped, most of them cannot even close the door. Sometimes the cable length is not enough and the joints do not meet the requirements. This is also a factor causing the failure.
Therefore, when buying a lawn lamp, highbay light manufacturer suggests that you must first try its quality.
