Embodiment 1

[0053] Such as figure 1 A tunnel lighting device utilizing sunlight is shown, comprising a light guide 1, the light guide 1 is connected with a diffuser 4 installed in the tunnel through an optical fiber, and the light guide 1 is also provided with a second An illumination sensor 16 and a lamp 5 , the first illumination sensor 16 is used to collect the illumination intensity in the light guide 1 , and the lamp 5 is used to adjust the illumination intensity in the light guide 1 .

[0054] In one or more embodiments, when the light intensity is greater than or equal to the preset value, the lamp is turned off, and the light intensity is the light intensity of sunlight in the light guide; when the light intensity is less than the preset value, the light is turned on, supplementing The light intensity in the light guide keeps the light intensity basically at the preset value to ensure sufficient illumination in the tunnel. In one or more embodiments, there may be multiple preset ...

Embodiment 2

[0061] On the basis of Example 1, such as Figure 1 to Figure 5 As shown, the outside of the light guide 1 is provided with a cooling jacket 6, and the cooling jacket 6 is connected with a first tube 7 and a second tube 8, and the first tube 7 and the second tube 8 are connected to the tunnel Internal communication, the first pipe 7 and / or the second pipe 8 is provided with a gas delivery unit 9, the gas delivery unit 9 is used to drive the gas in the cooling jacket 6 to flow to the tunnel, or the fluid in the tunnel to flow to the cooling jacket 6, A temperature sensor 17 is arranged inside the light guide 1 , and the temperature sensor 17 is used to collect the temperature inside the light guide 1 .

[0062] In some embodiments, the gas delivery unit may be any existing gas delivery device such as a blower or an air pump.

[0063] In one or more embodiments, the cooling jacket may be an annular cylindrical structure, and the inner space of the cooling jacket is the gas flow...

Embodiment 3

[0067] On the basis of the above examples, if Figure 1 to Figure 5 As shown, the light guide 1 includes a bottom plate 11, a lower section 13 and an upper section 14, the bottom plate 11 is provided with a guide groove 12, the guide groove 12 includes a cavity 121, and an air bag 122 is arranged in the cavity 121 , the bottom end of the lower section 13 is inserted into the guide groove 12 and located above the air bag 122, the upper end of the upper section 14 is connected to the cooling jacket 6; the gas delivery unit 9 is installed on the second pipe 8, so The second pipe 8 is inserted into the guide groove 12 and communicates with the air bag 122. The second pipe 8 is provided with a branch pipe 81, and the branch pipe 81 communicates with the inside of the cooling jacket (6);

Abstract

The invention discloses a tunnel lighting device, system and method using sunlight. The device comprising a light guide, wherein the light guide is connected to a diffuser mounted in a tunnel through an optical fiber, the light guide is also internally provided with a first illumination sensor and a lamp, the first illumination sensor is used for collecting illumination intensity in the light guide, and the lamp is used for detecting the illumination intensity in the light guide; the lamp is used for adjusting the illumination intensity in the light guide device. When illumination intensity in the light guide device is insufficient, illumination intensity is compensated by utilizing the illumination intensity of the lamp, and compensated illumination intensity is conducted to the diffuser through the optical fiber, so the light beams received in the diffuser are preliminarily mixed in the light guide device; and furthermore, the light emitted by the diffuser has no obvious brightness difference, chromatic aberration or color temperature change, illumination compensation is smoother, and a purpose of stepless dimming is achieved.

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...
