How to Troubleshoot Outdoor Garden Lights And Repairs

Common malfunctions of outdoor garden lights

There are two types of common faults: one is a high-impedance fault; the other is a low-impedance fault. The so-called high-resistance fault, that is, the cable is blown, the meter measuring resistance is large, or the insulation drops between the phases or the ground, but there is a certain resistance value; the so-called low-resistance fault, that is, the wire is short-circuited or completely shorted to the ground, the current Increase, the power transmission has a trip phenomenon. These two types of faults and their frequent occurrence pose a threat to the normal use of garden lights. Therefore, we must pay full attention to the reasons and countermeasures.

Cause of issue

1. Poor construction quality

The proportion of failures caused by construction quality is large. Main performances: First, the depth of the cable trench is not enough, the sand-covered bricks are not constructed according to the standard; the second is that the production and installation of the aisle tubes do not meet the requirements, the two ends are not made according to the standard; the third is when paving the cable The fourth pre-buried pipe is not constructed according to the standard requirements, mainly because the pre-buried pipe is too thin, plus a certain degree of camber, it is quite difficult to wear the cable, and there is a ” dead bend ” at the bottom of the foundation ; The wire nose crimping and insulation wrap are not thick enough, and after a long period of operation, the phases are short-circuited.

2. The material is not off

Judging from the fault conditions handled in recent years, the material quality is also low. The main performance is: the wire contains less aluminum, the wire is relatively hard, and the insulation layer is thin. This situation has been more common in recent years.

3. The quality of supporting projects is not too hard

Garden light cables are generally laid on the sidewalk. The construction quality of the sidewalk is poor, the ground sinks, and the cable is deformed by force, resulting in cable armoring. In particular, the northeastern region in China is in an extremely cold zone, and the arrival of winter makes the cable and soil form a whole. Once the ground subsides, it will be strained at the bottom of the garden light foundation, and when the rainwater is too much in summer, it will be blown at the base root.

4. The design is not reasonable

On the one hand, it is overloaded. With the continuous development of urban construction, the garden lights are also constantly extended. When the garden lights are newly built, which circuit lights are close to each other, which circuit is received, and in recent years, the advertising industry has developed rapidly, and the advertising load is also connected to the courtyard. On the lamp, the load of the garden lamp is too large, the cable is overheated, the wire nose is overheated, the insulation is lowered, and the grounding is short-circuited; on the other hand, the lamp post is designed only considering the condition of the lamp post, ignoring the space of the cable head, After the cable head is wrapped, most of the doors are not closed, sometimes the cable length is not enough, and the joint production does not meet the requirements, which is also a cause of failure.

Safeguard for garden landscape lighting

1. Strengthen training for maintenance personnel

On the one hand, urban garden lights are closely related to the life of the citizens. Its operation directly affects the image of the party and the government. It is necessary to improve the understanding of maintenance personnel on the maintenance work of garden lights and enhance the sense of responsibility. On the other hand, with the acceleration of the advancement of urban garden lighting technology, the extensive use of new technologies requires maintenance personnel to continuously update the maintenance expertise to meet the needs of the work.

2. Speed up the maintenance of maintenance equipment

The expansion of the city, the increase in the number of garden lights and the service area have greatly increased the workload of maintenance personnel. Without increasing the number of personnel, it is necessary to continuously improve and update the maintenance equipment to improve work efficiency.

3 .The implementation of the maintenance target responsibility system

On the basis of delineating the garden light management area, the maintenance responsibility system is implemented at all levels to implement the fixed person, fixed post, and responsibilities. It is necessary to conduct regular inspections, regular maintenance, and find out who is responsible for problems.

4. Strengthen law enforcement investigations

On the one hand, it speeds up the formulation of normative documents on the management of garden lights and creates conditions for legal management; on the other hand, the joint urban management department intensifies the enforcement of garden lights, seriously investigates and punishes the destruction of garden light facilities, and ensures the normal operation of garden light facilities.

Maintenance

1. Donot hang items on the lamp, such as drying cotton quilts.
2. 2.  frequent switching, which will greatly reduce its service life, so when using the luminaire, try to reduce the switch of the luminaire(So solar powered outdoor lights with automatic switch is perfect to fix this problem);
3. When the lamp cover is tilted during use or cleaning, it should be calibrated to maintain the appearance;
4. When adjusting the lampshade, take care to avoid the reflection of the shadow when the trigeminal bracket in the lamp is illuminated;
5. According to the light source parameters provided by the sign, replace the aging lamp in time, and find that the two ends of the lamp are red, the lamp is black or there is black shadow, and the lamp is not bright, the lamp should be replaced in time to prevent the ballast from appearing. Unsafe phenomena such as burnout.

Clean

1. Landscape garden lightingis generally dusty. When cleaning, use a wet rag to wipe it. Keep the movement in the same direction. Do not smear back and forth. The intensity should be moderate, especially for chandeliers and wall lamps.
2. Clean the inside of the lighting. When cleaning the bulb, first turn off the light. When wiping, you can remove the bulb separately.If cleaning directly on the luminaire, do not rotate the bulb clockwise to avoid over-tightening of the lamp cap.
