According to whether the LED roadway light can be directly installed on the surface of ordinary combustible materials, it can be divided into 2 categories. Factors causing LED roadway lighting to decline:   The light decay of LED products is the weakening of the signal of light in transmission. At this stage, LED products made by LED manufacturers have different degrees of light decay. Let’s take a look:   1. LED quality problems (1) The LED chip used is not in good condition, and the brightness decays quickly. (1) There are defects in the production process, and the heat dissipation of the LED chip cannot be exported from the PIN pin well, resulting in an excessively high temperature of the LED chip and aggravating the chip attenuation.   2, the use of conditions (1)The LED is driven by constant current, and some LEDs are driven by voltage to make the LED attenuate. (2) The drive current is greater than the rated drive condition. In fact, there are many reasons for the light decay of LED products. The key is the heat problem. Although many manufacturers do not pay special attention to the heat dissipation problem in the secondary products, the light decay degree of these secondary LED products will be higher than that of the ones that pay attention to heat dissipation under the long-term use of these secondary LED products. LED products are higher. The thermal resistance of the LED chip itself, the influence of silver glue, the heat dissipation effect of the substrate, and the colloid and gold wires are also related to light decay.   The above is the specific classification of LED roadway lights introduced by Xiaobian, as well as the specific factors that cause its light decay. If you have any doubts, please contact us in time!

What are the requirements for landscape lighting? This arrangement can get better results!

What are the requirements for landscape lighting? This arrangement can get better results!

  Landscape lighting is designed and created artificially to make it more artistic or aesthetic under the action of lighting, so that ordinary night scenes are full of exotic cultural atmosphere. Landscape lights should be the same color as the environment. Using light for color design is one of the key technologies in architectural design to reflect architectural cultural characteristics, and it has great benefits for architectural lighting. So what are the requirements for landscape lighting? It's going to do it! Take a look!     What are the requirements for landscape lighting? 1. Some important public buildings, historical relics, commercial buildings, square sculptures, or some special road signs (LANDMARK), bridges or MRT stations and other transportation facilities can be landscaped at night, so that the city night scene can be illuminated in addition to neon lights. There are different colors. 2. After reasonable planning, highlighting the landmark buildings, illuminating the road network, the outline of the city can be seen at night. Every city has its own unique cultural atmosphere, and it must be designed in a targeted manner. It cannot blindly imitate and imitate. It is always the shadow of others and has no bright spot. 3. A complete lighting project should have changes in spring, summer, autumn and winter, not just some important festivals. This reflects the unique charm and cultural atmosphere of a city!     Landscape lighting to do this: 1. With the continuous development of urban planning and construction and the continuous improvement of high-tech levels, the economic development of cultural tourism industry lighting projects has enriched its connotation. The lighting project of the scenic spot not only stipulates the light intensity, chromaticity, color rendering index, and the visual impact of the natural environment, which is pleasing to the eye, but also changes with the change of the scenery. 2. It has important practical significance to ensure the normal operation of lighting equipment in major cities and achieve better lighting effects. It mainly includes scientific management methods and legal management. Using modern control technology to carry out scientific management, not only to ensure the lighting rate and equipment integrity rate, but also to be economical and practical to achieve better lighting effects. 3. The lighting design of the building lighting project should proceed from the aesthetic point of view of the project building. In the design plan, the facade of the main building and the sub-building should be defined, and different actual lighting effects should be used to clarify the project sequence. The practical effects of various aspect ratios and different distances are more abundant.     The above is what are the requirements for landscape lighting? What it wants to do, if you want to know more information, you can pay attention to our later article updates to learn.

What are the characteristics of landscape lighting projects? How should it become environmentally friendly?

  Now many places are vigorously building landscape lighting projects, because it can not only make the night scene of the city more beautiful, but also attract more tourists to visit through the construction of night scenes, etc. What are the needs of this project? What characteristics are we going to understand? I will give you a detailed introduction in this article. In the process of building a landscape lighting project, it is also necessary to pay attention to making the landscape lighting project more environmentally friendly, so as to meet the current environmental protection concept of low carbon emissions!   What are the characteristics of landscape lighting? 1. The construction of landscape lighting in a city is a must, it can bring people spiritual pleasure and satisfaction. For example, lights can create and reshape regional landscapes, making night and day bloom different and wonderful, bringing people great spiritual enjoyment and stimulating the development of the local economy. 2. However, as an important element closely related to people's lives, landscape lighting cannot be done blindly, but must be targeted. Lighting is mainly used for services, serving the economy, cities and even various formats. Of course, in the final analysis, it is to serve people. Therefore, lighting needs to be people-oriented and serve various needs caused by people. 3. Night economy and night travel have great development prospects in the future. Therefore, it is an inevitable trend to "light up" cities and landscapes and create business cards for nighttime economy. As a particularly targeted customized design process, cultural and creative lighting is more conducive to creating independent IP and representative projects, and the prospects are promising. 4. As for the breakthrough in the future development of landscape lighting, the editor believes that we should start from three aspects. One is to return to the essence, do things according to the rules of industry development, and do not blindly expand the scale; Make planning and construction more reasonable and effective; the third is to practice internal skills diligently to consolidate the foundation.   How can landscape lighting projects become environmentally friendly?   1. Strengthen public consultation to realize the unity of top-level design and insisting on asking and considering the people   Landscape lighting needs to follow the people-oriented design concept, not blindly pursuing beauty and ignoring the impact on people's daily life, especially the residential area and its surrounding landscape lighting should be considered and designed with the comfort of living as the center, and landscape lighting should be Use soft and low color temperature lamps to avoid harsh light coming directly into your eyes. In functional lighting planning and landscape lighting planning, more emphasis is placed on citizen experience.   2. Implement dark night protection and lead the ecological restoration and dark night economy at night   It is helpful for ecological restoration at night, and the lights of landscape lighting cannot break the laws of nature. For observatories with specific requirements, the theme of observing the night environment and the dark environment should be based on the location and environment of the illuminated scene to determine the location, illumination angle, quantity and arrangement of lamps to avoid interfering light and glare, and reduce light pollution. And the starry sky at night. To sum up, the above is the relevant knowledge about landscape lighting project introduced by Xiaobian. When designing this project, you need to operate according to the knowledge suggested by Xiaobian!
