LED tunnel light technology application
Entering the new century, the state has increased the construction of transportation systems such as railways, highways, expressways, and high-speed railways. Tunnel lights must be installed in the tunnel, resulting in the large-scale LED tunnel light industry. LED tunnel lights have the incomparable advantages of traditional light source tunnel lights, energy saving and environmental protection, high brightness, high color index, long life, small size and easy installation, especially high-power LED tunnel lights, both brightness and service life are far beyond It replaces the traditional sodium lamp tunnel light and is currently the mainstream tunnel light product. Let's compare LED tunnel lights with traditional tunnel lights.
1. Function comparison and selection of conventional tunnel lights and LED tunnel lights
At present, traditional tunnel lighting mostly uses high-pressure sodium lamps as light sources, but high-pressure sodium lamps have many shortcomings in radiation form, color rendering, visual sensitivity, specifications, brightness control power, etc., while new LED tunnel lights, especially high-power LED tunnel lights With its superior performance, especially the controllability of brightness, lamps overcome the shortcomings of high-pressure sodium lamps and become the mainstream of tunnel lighting in today's world. The state has also introduced new measures for the semiconductor lighting project of "ten cities, ten thousand lights", which has brought unprecedented opportunities for the development of LED tunnel lights. In order to actively respond to the "Ten Cities, Ten Thousand People" plan, we have invested heavily in the introduction of advanced LED tunnel light production equipment from Europe, and vigorously developed and produced new LED tunnel lights. At present, LED tunnel lights occupy a decisive market share in China.
LED (Light Emitting Diode), or LED, is a semiconductor light-emitting technology. The earliest LEDs could only emit red light and were used for indicator lights in electronic devices. With the development of science and technology, LED lamps can now emit light of various colors and are widely used in many industries. The main application markets include traditional display and lamp markets, backlight sources, LED street lamps, LED tunnel lamps, and automotive lighting markets. , Outdoor landscape lighting and interior decoration lighting, special lighting market. LED has its unique advantages as a tunnel light source. (1) LED tunnel lights consume less power and save energy. Compared with high-pressure sodium lamps, it can save more than 60% of energy.
(2) LED tunnel lights have a long service life. Taking luna lighting high-power LED tunnel light as an example, its normal service life is more than 60,000 hours, which is more than 10 times the service life of sodium lamps. (3) LED tunnel lights have good working stability and are basically maintenance-free during use, while the later maintenance costs of sodium lamps are very high. (4) Reduce the construction cost of the power distribution system (cables, transformers, distribution boxes, bridges, etc.). In the case of long tunnels, long-distance power supply, cables and distribution facilities account for a large proportion of the cost. With LED tunnel lights, the investment in cables and power distribution equipment can be greatly reduced due to power saving. (5) The LED tunnel light can be started instantly, which is convenient for brightness adjustment. It has the advantages of no flicker, wide range of starting voltage, etc., and can realize various energy-saving methods such as intelligent adjustment of illumination according to road and tunnel traffic flow. Lunshen Lighting's new LED tunnel light can also realize intelligent control such as remote control and time-sharing control. (6) High-pressure sodium lamps, fluorescent lamps, and infinite lamps contain chemical pollutants such as mercury and lead, while LED tunnel light sources do not contain chemical pollutants and are green and environmentally friendly light sources. LED tunnel lights have passed the European standard ROHS certification. Environmental protection is a prerequisite for entering the European market.
