What are the main causes of LED garden lamp failure?
Dec 08, 2022
Generally, the main components of LED garden lamp are composed of five parts: light source, lamp, lamp pole, flange plate and foundation embedded parts. Because LED garden lamp has the characteristics of diversity, beauty and beautification of the environment, it is also called landscape garden lamp. It is mainly used for outdoor lighting in urban slow lanes, narrow lanes, residential areas, tourist attractions, parks, squares and other public places, which can prolong people's outdoor activities and improve property safety. What are the main causes of LED garden lamp failure? Let's explain:
1. Poor construction quality Courtyard lamp
Faults caused by construction quality account for a large proportion. Main performance: First, the depth of cable trench is not enough, and the construction of sand and brick covering is not carried out according to the standard; Second, the fabrication and installation of the aisle pipe did not meet the requirements, and the two ends were not made into mouthpieces according to the standard; The third is dragging on the ground when laying cables; 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, so it is very difficult to pass through the cable, and "dead bending" occurs at the bottom of the foundation; Fifthly, the thickness of the crimping and insulation wrapping of the wire nose is not enough, and the phase to phase short circuit will occur after a long time of operation.
2. Materials fail to pass the standard
Judging from the failures handled in recent years, the low quality of materials is also a major factor. The main performance is: the conductor contains less aluminum, the conductor is relatively hard, and the insulation layer is thin. This situation has been relatively common in recent years.
3. The quality of supporting works is not so good
The garden lamp cable is generally laid on the sidewalk. The construction quality of the sidewalk is poor, and the ground sinks, causing the cable to be stressed and deformed, resulting in cable armouring. In particular, the northeast region is located in the alpine zone. When winter comes, the cable and soil will form a whole. Once the ground subsides, it will be pulled at the bottom of the courtyard lamp foundation. In summer, when there is much rain, it will be burned at the root of the foundation.
4. Unreasonable design
On the one hand, it is overloaded operation. With the continuous development of urban construction, garden lights are also extending. When building new garden lights, they are often connected to the same circuit as the garden lights. In addition, the advertising industry has developed rapidly in recent years, and the advertising load is also connected to the garden lights accordingly, resulting in excessive load of garden lights, overheated cables, overheated wire noses, reduced insulation, short circuit to ground, etc; On the other hand, when designing the lamp pole, only the condition of the pole itself is considered, ignoring the space of the cable head. After the cable head is wrapped, most of the doors cannot be closed. Sometimes the cable length is not enough, and the joint fabrication does not meet the requirements, which is also the cause of the failure.
The above are the main reasons for the failure of LED garden lights. I hope it can help you.
