Trails and garden lights are actually a combination of two types of lights. The wholesale of garden lights pays attention to the landscape, and the lights of the walkways focus on functionality. The two can form their own systems separately, but after considering them, they still combine the two. It comes down to the garden light series.
Garden lamp manufacturers should pay attention to the following issues in their design:
1. The garden lights are mostly in the form of diffused light. The difference between diffused light and direct light is that it does not produce excessive shadows, making the color appear softer when it becomes brighter and darker. However, an important problem that needs to be solved in the field of diffused light is that the surface temperature of the illuminator is too high. As far as the popular garden lights on the market are concerned, few products can solve such problems.
2. Calculation of elevation angle and shoulder distance. The calculation of the elevation angle and the shoulder distance can achieve a good balance between the function and the landscape function. For example, if the design of the elevation angle takes into account the corresponding landscape design, then the role of the landscape can be better reflected. Meet people's needs.
The low-level luminaires first need to pay attention to the innovation of design concepts, followed by the humanization and diversity of functions. I saw a low-level lamp in Japan. This luminaire not only plays the role of lighting and beautification, but also plays a warning role. It tells passers-by that the front has a large curvature and many people in and out. Please be careful with drivers and road walkers. In order to achieve the versatility of the low-level lights and the integration of landscape lighting, it is necessary to introduce the idea of composite design and coordinate the function lighting and landscape lighting as much as possible.
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 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.
