LED lighting source applied to the analysis of road lamps
This article is about the analysis of the current problems in the application of LEDs in road lamps, is the idea and examples to solve the problem, for your reference only. As a novel solid illumination source, LED has a production process and almost no pollution, no vibration, easy to achieve 0~100% continuous dimming, can work under safe extra low voltage, can work continuously on switch flash The working state and its light output are directional and many other unique advantages. In recent years, its remarkable progress in light efficiency and light color has enabled it to enter commercial applications. However, due to the influence of China's planned economic industry layout and the lack of expertise in LED and the comprehensive knowledge of lighting appliances in the practitioners, there has been no application for the design and application of LEDs. Unreasonable and unqualified application products.
LED is used in the field of lighting. It is a hot topic in the lighting industry in China and the world. Through the continuous efforts of practitioners, the current system efficiency (including the driver circuit) of white LEDs for lighting under normal lighting conditions has reached 40lm/w. In addition, the manufacturing cost of LEDs for lighting has dropped significantly, so white LEDs for lighting have been put into commercial conditions for some lighting applications.
However, due to the situation caused by the industrial structure distribution of China for many years since the planned economy era, the current industrial groups that manufacture LEDs often lack understanding of the basic knowledge and requirements of lighting appliances, and the traditional lighting production groups are often lacking. In-depth understanding of the LED characteristics of lighting, in the design and application of the characteristics of the LED is not fully utilized, to promote the use of long and short, so that when the lighting LED is applied to the lighting device, there are many unreasonable misdesigns.
