offline programming, three-in-one dimming, positive and negative logic dimming, etc., which can meet the lighting needs in tunnel scenes. In the tunnel lighting system, the negative logic dimming function plays an important role. When the dimming line of the tunnel lamp is short-circuited or other faults occur, the negative logic dimming function can ensure that the lamp maintains the maximum brightness, thereby providing better lighting effects and ensuring driving safety. At the same time, the light can be dimmed according to actual needs to achieve on-demand lighting and save energy.

As a company focusing on the research and development, production, sales and service of lighting power solutions, Dongling Power has always adhered to the corporate philosophy of "customer-centric and value creator-oriented" to provide customers with high-quality, reliable and efficient power products. This time, Dongling Power's MAS series LED power supply assisted the lighting construction of the Yuegui Tunnel and Tangwu Tunnel of the Erguang Expressway, which is another important achievement of Dongling Power in the field of infrastructure construction.

In the future, Donling Power will continue to focus on the development needs of infrastructure construction, and provide more reliable power solutions for my country's tunnel lighting, highways and other high-power lighting fields with innovative technologies, high-quality products and services, and contribute to promoting my country's regional economic development and green development.
