Problems solved by technology

[0002] When entering the existing tunnel, because the vision will suddenly become black, for the driver, it is very likely that a black hole phenomenon will appear. Although under normal circumstances, it only takes a few seconds to recover, but for the driver, this A few seconds is enough for some traffic accidents

Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0043] As shown in the figure, the lighting equipment applicable to the entrance of the tunnel involved in this technical solution includes:

[0044] The light concentrating part, located outside the tunnel entrance, is used to receive external light and converge the light into light beams;

[0045] The light guide part is located at the top of the tunnel and is used to receive the light beam from the light collecting part;

[0046] The light exit part is connected with the exit end of the light guide part, is located at the top of the tunnel, and is used for illuminating the light beam into the tunnel.

[0047] In general, the sunlight at the entrance of the tunnel is gathered and condensed i...

Abstract

The invention discloses a lighting device suitable for a tunnel portal. The lighting device comprises a light gathering part located on the outer side of the tunnel portal and used for receiving outerillumination and gathering illumination into a light beam, a light guide part located on the inner top of the tunnel and used for receiving the light beam from the light gathering part, and a light emitting part connected with the outlet end of the light guide part, located on the inner top of the tunnel and used for irradiating the light beam into the tunnel; the included angle between the lightemitting direction of the light emitting part and the direction for entering of the tunnel is an acute angle, a light blocking plate is perpendicular to the illumination, one end of the light blocking plate is located in the light guide part, and used for blocking illumination transmission, and the other end of the light blocking plate is dragged by a bearing plate. The lighting device has the beneficial effects that the lighting device with the self-adjusted inner light beam and used in the tunnel portal is provided, and the black hole phenomenon appearing when a driver enters the tunnel canbe avoided.

Description

technical field [0001] The invention relates to a lighting device suitable for tunnel entrances. Background technique [0002] When entering the existing tunnel, because the vision will suddenly become black, for the driver, it is very likely that a black hole phenomenon will appear. Although under normal circumstances, it only takes a few seconds to recover, but for the driver, this A few seconds is enough for some traffic accidents to happen. [0003] Therefore, in order to avoid the occurrence of this kind of image, it is necessary to add some equipment at the tunnel entrance. Contents of the invention [0004] A lighting device suitable for a tunnel entrance, characterized in that: [0005] Daylighting devices suitable for tunnel entrances include: [0006] The light concentrating part, located outside the tunnel entrance, is used to receive external light and converge the light into light beams; [0007] The light guide part is located at the top of the tunnel and...
