1、 LED tunnel light
1. High luminous efficiency, high brightness LED light source
2. Scientific and reasonable light distribution, meeting the lighting uniformity and anti glare requirements of various sections of the tunnel
3. Modular design of the light source, each module can be installed and disassembled separately, making maintenance convenient and fast, reducing a series of costs
4. Rich series of products, which can meet the introduction and transition sections of the tunnel The lighting requirements for the four sections of the basic and exit section lights are as follows:. It is a lighting device without electrodes and filaments, which generates electromagnetic waves through the magnetic ring outside the lamp tube to excite the material inside the lamp tube to work. For example, a low-pressure gas electrodeless lamp is filled with a mixture of mercury vapor and rare gases. The mercury atoms are ionized and excited, releasing ultraviolet light to illuminate the fluorescent material on the lamp wall, which emits visible light. Although also filled with mercury, its solid mercury content is lower than that of fluorescent lamps. Its operating frequency usually reaches millions of hertz, far higher than ordinary incandescent lamps and energy-saving lamps. Due to the elimination of filaments and electrodes, it can be made into various shapes such as rings, spirals, or tubes. Its working life can reach nearly 100000 hours and its work efficiency is also very high
Thirdly, sodium tunnel lamp
