[0033] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] The utility model provides an uninterrupted light source tunnel lighting fixture, which includes a plurality of lamps 1 distributed along the extension direction of the tunnel; the light angles of adjacent lamps 1 along the tunnel direction overlap. Specifically in this embodiment, the lamps 1 are preferably long strip tunnel lamps, and the tunnel lamps are in a tightly fitted continuous distribution structure to increase the overlap of the light angles of adjacent lamps 1 along the tunnel direction as much as possible, and reduce the number of lamps arranged along the tunnel direction (further reducing the empty area of ​​illumination and reducing the flicker).

[0035] Preferably, several of the lamps are distributed in a straight line to form a structure similar to a "light belt", and in order to increase the lighting effect in the tunnel, multiple "light belts" can be installed in the tunnel.

[0036] In addition, the light path formed by the plurality of lamps is divided into a plurality of sections along the tunnel direction and the light source is adjusted based on the sections as a whole. In order to improve the eye adaptation of the driver when entering and exiting the tunnel, the light intensity is adjusted according to the following embodiments.

[0037] See also Figure 1 to Figure 7 In this embodiment, the optical path channel is divided into seven sections along the tunnel direction, which are distributed from the tunnel entrance direction to the tunnel exit direction in sequence:

[0038] Section 1: Length 45 meters; enhanced lighting uses a row of 300W lamps, with a lamp height of 5.6 meters, and the lights are arranged symmetrically and continuously on both sides of the tunnel; basic lighting and emergency lighting use a row of 20W lamps (located on the side of the enhanced lighting), with a lamp height of 5.4 meters, and the lights are arranged symmetrically and continuously on both sides of the tunnel.

[0039] Section 2: Length 45 meters; enhanced lighting uses 1 row of 150W lamps, with a lamp height of 5.6 meters, and the lights are arranged symmetrically and continuously on both sides of the tunnel; basic lighting and emergency lighting uses 1 row of 20W lamps, with a lamp height of 5.4 meters, and the lights are arranged symmetrically and continuously on both sides of the tunnel.

[0040] Section three: It is a transition section with a length of 75 meters. The enhanced lighting uses a row of 60W lamps with a height of 5.6 meters. The lights are arranged symmetrically and continuously on both sides of the tunnel. The basic lighting and emergency lighting use a row of 20W lamps with a height of 5.4 meters. The lights are arranged symmetrically and continuously on both sides of the tunnel.

[0041] Section 4: It is a transition section with a length of 90 meters. The enhanced lighting uses a row of 20W lamps with a height of 5.6 meters. The lights are arranged symmetrically and continuously on both sides of the tunnel. The basic lighting and emergency lighting use a row of 20W lamps with a height of 5.4 meters. The lights are arranged symmetrically and continuously on both sides of the tunnel.

[0042] Section 5: The middle section is 13,565 meters long. The length of the NK middle section is 13,520 meters. The basic lighting and emergency lighting use a row of 20W lamps with a lamp height of 5.4 meters. The lights are arranged symmetrically and continuously on both sides of the tunnel.

[0043] Section six: Length 30 meters; enhanced lighting uses a row of 30W lamps, with a lamp height of 5.6 meters, and the lights are arranged symmetrically and continuously on both sides of the tunnel; basic lighting and emergency lighting uses a row of 20W lamps, with a lamp height of 5.4 meters, and the lights are arranged symmetrically and continuously on both sides of the tunnel.

[0044] Section seven: Length 30 meters; enhanced lighting uses 1 row of 45W lamps, with a lamp height of 5.6 meters, and the lights are arranged symmetrically and continuously on both sides of the tunnel; basic lighting and emergency lighting uses 1 row of 20W lamps, with a lamp height of 5.4 meters, and the lights are arranged symmetrically and continuously on both sides of the tunnel.

[0045] See also Figure 8 and Fig. 9 The utility model provides an uninterrupted light source tunnel lighting fixture, specifically including the lamp body 2 and a fixed bracket 3 installed on the inner wall of the tunnel; the lamp body 2 and the fixed bracket 3 are rotatably connected and positioned by a positioning assembly after the lamp body 2 is rotated to a desired angle; in this embodiment, a positioning bracket 21 is installed on the lamp body 2, and the positioning bracket 21 and the fixed bracket 3 are connected in a hinged manner, and the positioning assembly adopts a traditional bolt positioning structure. Specifically, an arc groove 31 is provided on the fixed bracket 3, and a positioning bolt is screwed on the positioning bracket 21, and the positioning bolt is placed in the arc groove 31. When adjusting the angle of the lamp body 2, it is only necessary to loosen the positioning bolt (the positioning bolt cancels the pressing and fixing), so that the positioning bolt can slide in the arc groove 31, and after the lamp body 2 is rotated to the desired installation angle, tighten the positioning bolt, and the positioning bolt uses the bolt cap and the threaded structure to achieve the pressing between the positioning bracket 21 and the fixed bracket 3, and further achieves the rotation locking.

[0046] During the installation of multiple groups of lamps, in order to ensure the matching relationship between the lamps, it is necessary to further ensure that the installation angles of the lamps are almost consistent. However, the traditional angle positioning method used in the installation of lamps is relatively laborious (a scale is provided at the hinge of the positioning bracket 21 and the fixed bracket 3, and the scale is used for comparison during angle positioning). Therefore, in order to facilitate the installation of lamps, the present application has been improved in the following ways: the side wall of the lamp body 2 is provided with a positioning part 4 which is always perpendicular to the rotatable direction of the lamp body 2 and realizes the angle positioning of the adjacent lamps 1. The positioning part 4 is a plate-like structure, a columnar structure, etc. During installation, after the angle of one of the lamps is positioned, the angle of the lamp at the adjacent position can be positioned by the positioning part 4 provided thereon. During specific use, after the side wall of the lamp 1 at the adjacent position is fitted with the positioning part 4, the angle confirmation is completed.

[0047] In order to prevent the positioning part 4 from being damaged during transportation, the positioning part 4 is installed on the side wall of the lamp body 2 in a telescopic manner, and extends outward from a preset end face or retracts into the end face. When working, the positioning part 4 extends; during transportation, the positioning part 4 is in a retracted state; the preset end face is the opposite end face between adjacent lamp bodies 2. Specifically, a housing 6 for placing the positioning part 4 and having an opening 61 is installed on the side wall of the lamp body 2; the positioning part 4 is slidably installed in the housing 6 and can extend from the opening 61.

[0048] Preferably, a driving spring 7 for driving the positioning portion 4 to extend outward is installed in the housing 6, and the driving spring 7 is used to conveniently drive the positioning portion 4 to extend out of the housing 6. A handle structure may also be provided at the end of the positioning portion 4.

[0049] See also Fig.10 , Fig.11 , Fig.12 and Fig.13 A positioning pin 8 for locking the sliding position of the positioning part 4 is installed on the accommodating shell 6. The positioning pin 8 is used to lock the state of the positioning part 4 in the retracted state to prevent the positioning part 4 from extending out of the accommodating shell 6 during transportation; the positioning pin 8 is slidably installed on the accommodating shell 6, and the positioning part 4 is provided with an embedding groove 9 that cooperates with the positioning pin 8; the positioning pin 8 moves downward into the embedding groove 9 to realize the position positioning of the positioning part 4.

[0050] When the positioning part 4 is extending, the positioning pin 8 is firstly released from its position, that is, the positioning pin 8 is driven (by hand) to move upward and out of the embedding groove 9 . Then, the positioning part 4 is extended from the accommodating housing 6 under the action of the driving spring 7 .

[0051] During the retraction process of the positioning portion 4, the positioning portion 4 is pressed to retract into the accommodating housing 6. Then, the positioning pin 8 is driven to move downward and enter into the embedding groove 9.

[0052] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
