Abstract

A tunnel lighting device, system and method using sunlight, the device includes a light guide, the light guide is connected with a diffuser installed in the tunnel through an optical fiber, and a first An illumination sensor and a lamp, the first illumination sensor is used to collect the light intensity in the light guide, and the light is used to adjust the light intensity in the light guide. In the present invention, when the light intensity in the light guide is insufficient, the illuminance of the lamp is used to compensate the light intensity, and the compensated light intensity is transmitted to the diffuser through the optical fiber, so that the light beam received in the diffuser is in the light guide. The light beam that has been preliminarily mixed in the diffuser, and the light emitted by the diffuser has no obvious brightness difference, color difference or color temperature change, and the compensation of light is smoother, achieving the purpose of stepless dimming.

Description

technical field

[0001] The invention relates to the field of tunnel lighting systems, in particular to a tunnel lighting device, system and method utilizing sunlight. Background technique

[0002] With the improvement of my country's economic level and the development of highway construction, the construction of highway tunnels is increasing day by day, the scale and quantity of tunnel lighting facilities are also increasing, and the operating electricity and maintenance costs of tunnels are also increasing. Establishing a safe, economical and energy-saving tunnel lighting system is the key to reducing tunnel operating costs.

[0003] At present, the lighting methods in tunnels are mainly high-pressure sodium lamps, LED lamps, or a combination of high-pressure sodium lamps and LED lamps. But no matter which lighting method is used, it needs to consume a lot of electric energy, and the lamps need to be regularly maintained and replaced, which requires a lot of manpower, fina...
