1 Overview
In recent years, with the construction and development of Beijing, the environment has played a unique and important role in beautifying the city, creating a beautiful environment and facilitating community life, especially the beautiful project of Beijing urban garden roads on the 50th anniversary of this year. Implementation, but beautified the urban environment, and has been appreciated by all sectors of society, but also from the sociological point of view of the impact and significance of environmental lighting on my social life.
2 Features
In the past, we have divided lighting from environmental places into indoor lighting and outdoor lighting, while outdoor lighting is mainly functional lighting. In recent years, outdoor environmental lighting has gradually improved, not only functional lighting, but also parks, communities, gardens, greenery, gardens, squares, street sculptures, sketches, advertisements and other landscape lighting inside and outside the hotel. Gradually develop into a comprehensive lighting system for urban environmental art.
3 Design principles
I have undertaken a lot of outdoor environmental lighting design for many years. Some experience: Environmental lighting design should follow the following principles:
3.1 Environmental Principles: The types of lamps that can be used for ambient lighting are more extensive, especially the influx of imported lamps in the past one or two years, and the range of options is more abundant. However, in the design of ambient lighting, the choice of lamp type and light source must be consistent with the same-sided environment style of the installation place of the lamp. For example, community landscape layout, architectural style, landscaping plant varieties and many other factors need to be considered together. Because ambient lighting fixtures have the function of embellishing and beautifying the environment during the day, in addition to the nighttime lighting function.
3.2 Safety principle: The installation place of environmental lighting fixtures is the first place for people's daily life and entertainment activities to protect people. This requires environmental lighting design must have leakage protection and a good grounding system. The equipment selection must meet the safety protection level standards, and must be strictly controlled in accordance with the regulations to ensure electrical safety.
3.3 Reasonable principle: The design of environmental lighting should be based on the various landscape characteristics of the environment, and must be consistent in style and reasonable in design. During the day, it is decorated with a landscaping environment, and the nighttime illumination is moderate, avoiding blind spots (dark areas) and preventing light pollution. For example, many of the lanterns were installed in the bright project of the 50th anniversary of this year. The beautiful and varied lighting has been loved by people and brought a happy atmosphere to the city. However, the installation location of individual lamps is too close to the residential building, which has formed light pollution and affected the lives of nearby residents. The light pole in the small area is too high or too close to the residential building, causing light interference to the residents.
4 Lighting fixtures
There are many types of lighting fixtures used in environmental places, especially in the garden environment, and various types of imported lamps also account for a large proportion. National Day project, the main greenery in front of Chang'an Avenue is basically using imported lamps. Imported lamps have a high degree of protection, high safety and good performance, but the price is high. The use of environmental lighting must be designed according to the requirements of environmental, functional, aesthetic and other factors, as briefly described below.
4.1 Determine the luminaire according to the location and surrounding environment. In public places (such as parks and residential areas, street parks), due to the large number of people flowing, the choice of lamps should take into account the destructive and safe performance of human beings. High-end residential quarters, hotel gardens, square front area, you can choose the shape and non-standard decorative lights according to the surrounding architectural environment (for example, the stone decorative lighting can achieve the lighting effect and meet the viewing requirements of art pieces). Lighting We use a lot in landscaping such as Donghuan Square.
4.2 Park road lighting should be greened in the park, the architectural style characteristics are determined (mainly based on functional lighting), and the pole height is positioned at 2.5~3m. Because the road width in the cell is generally less than 5m, the interval between lamps is generally about 15m. The diameter of the green space is generally about 2m wide. It is better to set the height of the 800mm lawn lamp. However, according to the environment on both sides of the road, the higher-grade community has two-way ground lighting on one side of the lawn, one side of the road lighting and the other side of the lawn lighting. The effect is very good. .
4.3 Underwater landscape photo: There are a lot of dry fountains in the park, underwater lighting, and the change of lighting adds color to the fountain. We are designing underwater lighting fixtures that are replaced by optical fibers. As a new type of illuminator, fiber optic lamps are a relatively advanced technology in China. The waterscape lighting of the dry fountains of Ocean Building and Jinyu Building is mainly based on fiber optic lighting. The use of fiber optic lamps for waterscape lighting has an irreplaceable advantage over underwater lights. First of all, fiber optic lamps save energy. A light source generator 150W can carry 7 luminous points, which can replace 7 underwater lights (80W for each set of underwater lamps). Secondly, because the fiber is in the water, the light source is not in the water. It makes its security performance greatly improved. Each spot can be free to change seven colors, which are not possible with underwater lights. Construction and maintenance are very convenient. The diameter of the output end of the fiber is only 30mm, and the diameter of the fiber is 14mm. It only needs to be fixed with the nozzle when it is used. The original underwater lamp has a minimum diameter of 100mm. It must be opened during construction. A hole larger than 100mm has a shorter life than a fiber optic luminaire.
4.3 Decorative lighting: Landscape, garden, urban green lighting In the past, it was only very simple to set up some functional lighting, such as garden road lighting. In recent years, decorative lighting has been gradually developed, such as lawn lighting, small sculpture lighting, trees, flowers and lanterns, all of which have outstanding aesthetic tastes, focusing on the style and characteristics of the garden environment. However, there is no illumination standard for garden night lighting in China. Therefore, there is no accurate scientific basis in the design. Since last year. The landscaping landscape lighting is just getting started. Last year, we undertook the floodlighting of the trees in the front of the industrial and commercial sector. Before that, Beijing also had some trees floodlighting. Although the lighting effect was achieved, the shape of the lamp was like a big iron box, and the tree was circled. This affected the surrounding beautiful environment and used hedges or trees. The pool circled the lights and it was not safe. In our design, we used buried embedded floodlights to make people not see the lamps. In the area with pedestrians, a built-in anti-glare grille is added to the luminaire. The hedge is short and wide. In order to prevent glare, a biased light buried lamp is used. A built-in directional anti-glare device is installed in the lamp, and a light source of 5000K color temperature is used to highlight the greening, and is contrasted with the yellow light of the road lighting. In a conditional environment, if the lamp can be concealed, a pin-type projection lamp can also be used.
4.4 Light source selection: Garden road lighting source generally adopts metal halide lamp with high efficiency and good color rendering. Long life, but high initial investment. The lawn lamp lighting uses energy-saving lamps, and the decorative lighting selects metal halide or incandescent lamps (reflective lamps) according to the landscape to be photographed.
Flex-rigid PCB
Flex-rigid PCBs are Printed Circuit Boards highlighted by both rigid and flexible areas that make them ideally suited for a wide range of applications. The typical rigid-flex PCB circuit includes two or more conductive layers that comprise either flexible or rigid insulation material between each one - the outer layers may have either exposed pads or covers. Conductors are found on the rigid layers, while plated through-holes are found in both the rigid and flexible layers.
The Advantages of Flex-Rigid PCB Technology
While this type of flexible circuit may be more expensive to design and produce, it does offer a number of important advantages. For instance, the reduced size makes it easier to fit more components into a smaller space. This can actually help to lower overall system costs. Additionally, because they require the need for fewer interconnects and related parts and components, these Flexible Circuit Board can also prove to be more reliable and require less maintenance in the long run.
As with all types of flexible circuit boards, the flex-rigid PCB will perform well in even the harshest environments, especially those featuring extreme heat. A Rigid Flex board is also easy to test, making it well-suited for prototyping.
