Description

ASP LED Highway Tunnel Lighting System

technical field

The utility model relates to the field of an energy-saving and environment-friendly tunnel lighting system, in particular to a highway tunnel lighting field which uses a wind-solar complementary power generation system for power supply, a stepless dimming control system to adjust the tunnel lighting brightness, and a safety monitoring system to monitor the whole process. the

Background technique

Highway tunnels belong to lighting with large illumination area and high brightness requirements. At present, highway tunnel lighting mostly uses commercial power. During its operation, tunnel lighting consumes a lot of power and wastes a lot of energy. It does not meet the requirements of a resource-saving and environment-friendly society advocated by my country at this stage. Therefore, it is not necessary to use environmentally friendly energy for power supply. Adopting a reasonable energy-saving solution is a good way to improve the tunnel lighting system. the

Both solar energy and wind energy are inexhaustible renewable green energy sources, and the two energy sources are highly complementary in terms of utilization time and location. The wind-solar hybrid power generation system using solar and wind power has excellent matching in terms of resources, so the wind-solar hybrid power generation system is applied in many regions of China. However, at present, domestic wind-solar hybrid power generation systems generally have disadvantages such as low light efficiency, high heat consumption, and short service life. the

To improve the power generation efficiency of the solar power generation system, the method of keeping the incident angle of sunlight at a right angle can be adopted. As we all know, the sun will move from east to west in a day. If the solar power generation panel is fixed, the sunlight can only shine directly on the power generation panel for a period of time. amount decreased. Therefore, in order to improve the power generation efficiency of the solar power generation system, it is necessary to use a device that tracks the movement of the sun to ensure that the sun's rays shine directly on the power generation panel as much as possible. the

Improving the power generation efficiency of wind power generation system is mainly to maintain the stability of power generation voltage and expand the working range of wind power generation. The output characteristics of wind power generation are highly random, and the speed of the fan is often unstable, resulting in low power quality and unstable voltage frequency, which may cause a large impact on the charging equipment. Output stability is important. Secondly, equipped with advanced electronic monitoring system and automatic adjustment system for wind power generation, it can ensure that the wind turbines can work normally no matter in the case of light wind or strong wind, and greatly improve the efficiency of wind power generation. the

According to the "Code for Design of Ventilation and Lighting of Highway Tunnels", highway tunnel lighting can usually be divided into four parts: entrance section lighting, transition section lighting, middle section lighting and exit section lighting. From the perspective of driving safety, the power and distribution of lamps in the tunnel are generally determined based on the maximum brightness and the fastest driving speed on the brightest day outside the tunnel throughout the year. If the tunnel lighting is carried out according to this design during the day, it will inevitably cause a lot of waste of electric energy. Therefore, tunnel lighting designers have proposed some lighting control schemes at this stage. However, these control schemes are basically controlled by switching loops. The construction of this kind of lighting circuit is difficult, the construction investment is large, and when the lighting is dimmed, the lamps cannot be dimmed in stages, and only some of the lamps can be selectively turned on or off. Such tunnel lighting is prone to "zebra effect". Poor uniformity seriously affects driving safety and comfort. the
