Analysis of Pain Points and Difficulties in Landscape Lighting Illumination

Landscape lighting plays an important role in enhancing urban image and creating a nighttime atmosphere, but in the implementation process, it also faces many pain points and difficulties.
Unreasonable planning and design: The landscape lighting in some areas lacks overall planning, with each region acting independently, resulting in chaotic lighting effects and a lack of coordination and hierarchy. The color matching of some buildings' lighting is too fancy, and the brightness and color contrast between adjacent buildings are extremely large, without forming an organic and unified nighttime visual landscape. This not only fails to showcase the city's characteristics, but also gives people a sense of disorder. Moreover, many landscape lighting designs have not fully considered the surrounding environment and residents' living needs. Some lighting fixtures are installed improperly, and the lights directly shine on residents' windows, seriously affecting their normal sleep and causing dissatisfaction, which in turn hinders the progress of the project.

Energy consumption and cost issues: Landscape lighting requires a large amount of electricity, especially in large commercial complexes, municipal squares, and other areas where high-intensity lighting fixtures are used for extended periods of time, resulting in high electricity bills. For the operator, this is a significant economic burden and does not conform to the current development concept of energy conservation and emission reduction. At the same time, the procurement, installation, maintenance, and subsequent system upgrades and renovations of lighting fixtures require significant investment. Some high-end lighting fixtures with special effects are expensive, while some slightly lower quality fixtures have low initial procurement costs but are frequently damaged, resulting in a significant increase in maintenance costs in the later stage. This puts many projects in a dilemma in terms of capital investment, making it difficult to control costs while ensuring lighting effects.

Difficulty in maintenance and management: Outdoor lighting fixtures are exposed to natural environments for a long time and are susceptible to erosion from wind, sun, rain, dust, and other factors, which can lead to damage, aging, fading, and other issues. For example, faults such as broken lampshades, burnt bulbs, and rusted lamp posts occur frequently, and the distribution range of lighting fixtures is often wide, which increases the difficulty of troubleshooting and maintenance. In addition, some landscape lighting projects use complex control systems, which require professional technicians to debug and repair in case of malfunctions. However, due to the limited number of technicians or uneven technical levels, timely maintenance often occurs, affecting the normal presentation of lighting effects and reducing the overall utilization and viewing value of landscape lighting.

Light pollution problem: Excessive or unreasonable lighting can cause light pollution, endangering human health and the ecological environment. For example, excessive lighting can disrupt the body's circadian rhythm, affect sleep quality, and long-term exposure to light pollution may even lead to health problems such as insomnia and anxiety. Moreover, light pollution can also affect astronomical observations, making the urban night sky too bright and obscuring the radiance of stars, which is not conducive to the development of astronomical science popularization activities and astronomical research.

To achieve sustainable development, landscape lighting projects must face these pain points and difficulties. Through scientific and reasonable planning and design, the application of energy-saving technologies, efficient maintenance and management measures, and effective prevention and control of light pollution, landscape lighting can truly illuminate the urban night sky and create a beautiful, comfortable, and environmentally friendly nighttime environment for people.
