[FOCUS] Analysis of LED Lighting Sources Applied to Road Lighting

This article is an analysis of the current problems in the use of LED lamps in road lighting, is to solve the problem of ideas and examples, only for your reference. As a novel solid-state lighting source, LED has almost no pollution in the production process and products, is not afraid of vibration, can easily achieve 0 to 100% continuous dimming, can work under safe extra-low voltage, and can work continuously on the switch flash Its working status and its light output are directional and many other unique advantages. In recent years, significant advances in its light efficiency and light color have enabled it to enter commercial applications. However, due to the impact of China's planned economic industrial layout, and the lack of professional knowledge of LED and general knowledge of lighting appliances among employees, it has caused many applications in the actual design and application that do not have advantages and disadvantages. Unreasonable and unqualified application products.

LED is used in the field of lighting and is currently a hot topic in the lighting industry in China and even in the world. With the constant efforts of employees, the system efficiency (including the drive circuit) of the white LED used in lighting under normal lighting conditions has reached 40lm/w. In addition, the manufacturing cost of LEDs for lighting has dropped drastically, so white LEDs for lighting have been used in commercial applications in some lighting fields.

However, due to the situation caused by the distribution of industrial structure in China for many years since the planned economy era, the current industrial groups that manufacture lighting LEDs often lack understanding of the basic knowledge and requirements of lighting appliances, and traditional lighting production groups often lack The in-depth understanding of the characteristics of the lighting LED, in the design and application did not take full advantage of the characteristics of the LED, to avoid the use of advantages, so that when the lighting LED is applied to the lighting device, resulting in a lot of unreasonable error design.
