[ detailed description ] embodiments

The invention is further described with reference to the following figures and examples.

Referring to fig. 1, the tunnel lamp 200 of the present invention is installed on a wall in a tunnel 100 to illuminate the tunnel, and specifically, in this embodiment, the tunnel lamp includes a bracket 10, a power supply 20, a lamp holder 30, a heat sink 40, a lamp panel 50, and a lens module 60; the two side plates of the lamp holder 30 are rotatably mounted on the bracket 10, and the bracket 10 is fixed on a wall in a tunnel, and the specific structure of the bracket 10 will be further described below. As shown in fig. 1, a plurality of radiators 40 are fixed on the back of the lamp holder 30 side by side, the power supply 20 is fixedly installed behind the radiators 40, the lamp panel 50 is fixedly installed on the front of the lamp holder 30, and the heat emitted by the lamp panel 50 is transferred by the lamp holder 30 and is emitted by the radiators 40; further, lens module 60 covers on lamp plate 50, is provided with the dull polish layer 601 that forms through dull polish processing on the light-emitting position on the lens module 60, and this dull polish layer 601 has realized the secondary light-emitting of light, promotes the luminous efficiency of actual road lighting to the highest, and unnecessary veiling glare disperses unnecessary veiling glare through surperficial lens surface dull polish processing, avoids causing the influence because of the light that sends to the driver. As shown in fig. 2 and 3, an acute angle formed between the lamp panel 50 and the wall in the tunnel is 5 °, and the lamp panel 50 is inclined toward the traffic flow direction, and due to the inclination of the lamp panel 50 and the existence of the lens module 60, an included angle formed between the light emitted by the lamp panel 50 and the traffic flow direction in the tunnel after being refracted by the lens module 60 is 58 °; the design of this kind of structure for penetrate driver's light directly less and even for soft light, lens partly adopts dull polish simultaneously, can make the light that the vehicle left sees through the rear-view mirror direction soft, does not influence driving safety.

In the above embodiment, as shown in fig. 1 and fig. 3, a plurality of lamp panels 50 are arranged on the lamp holder 30 in an array, each lamp panel 50 is provided with a plurality of LED lamp beads, the lens module 60 is provided with light emitting protrusions 602 at positions corresponding to each LED lamp bead, and the frosted layer 601 is located on the outer surfaces of the light emitting protrusions 602; as shown in fig. 3, in this embodiment, this protruding 602 of light-emitting comprises two consecutive arcs protruding, and the bellied slope of one of them arc is greater than the bellied slope of another arc, lamp plate 50 is the tilt state, the less arc protruding one end that is located relative position on lamp plate 50 of slope, through this kind of structure, adjust the angle of the light that LED lamp pearl sent, the contained angle that makes the light that LED lamp pearl sent and traffic flow direction in the tunnel is 58, this kind of light-emitting angle can be the best avoids forming perpendicular incidence to the driver.

In order to improve the waterproof performance, in the above embodiment, the lens module 60 and the lamp panel 50 are further provided with an annular waterproof silica gel 70 therebetween, and the screw 80 sequentially passes through the lens module 60, the waterproof silica gel 70 and the lamp panel 50 and is fixed on the lamp holder 30.
