Problems solved by technology

[0003] Since the tunnel lighting facilities need to work continuously, the working environment is continuously high temperature, but the burden brought by the continuous high temperature to electrical equipment cannot be ignored, such as the aging of the circuit, and even the possibility of short circuit and fire hazard caused by high temperature Sex also increases geometrically
[0004] Chinese Patent Announcement No. CN207094308U, a kind of one-way tunnel lighting, CN206973378U, a kind of municipal tunnel lighting, etc. proposed different technical solutions respectively, but similar to most of the existing tunnel lighting, most of them just solve the problem of the illumination angle of the lighting , but as we all know, in order to avoid the "hysteresis of adaptation", the tunnel lamp needs to be kept fixed for a long time after calculating the irradiation angle, but these applications all solve the heat dissipation problem of the tunnel lamp during long-term use, and the existing Most of the advanced technologies only add multiple heat sinks outside the lamp housing, and due to the electrostatic effect, under long-term working conditions, dust will accumulate, which is very unfavorable for heat dissipation.

Embodiment 1

[0019] see Figure 1-3 , a safety tunnel lighting device, comprising a cuboid lamp body 1, the lamp body 1 has an inner cavity 15 inside, the top of the inner cavity 15 has a light-concentrating surface 17, and a plurality of lamp beads 16 are attached to the center of the top of the inner cavity 15 , the bottom of the inner cavity 15 has a flat glass layer 14, and a controller 13 is arranged on the top surface of the lamp body 1. The controller 13 is electrically connected to the lamp bead 16, and the controller 13 is connected to the power supply system through a line. A plurality of lamp beads 16 are energized to emit light, and gather the emitted light through the light-gathering surface 17 to provide illumination for the inside of the tunnel; There is a "U"-shaped heat dissipation channel 3, and a chute 5 is opened on the top of both sides of the protective cover 2, and a sliding filter 4 that is slidably connected to it through the slider 6 is provided in the chute 5, an...

Embodiment 2

[0024] On the basis of Embodiment 1, in order to further improve the heat dissipation effect, an exhaust fan is provided on both sides of the protective cover 2, and the exhaust fan is electrically connected to the controller 13, and the exhaust fan accelerates the heat dissipation in the heat dissipation channel 3. The air flow rate can improve the heat dissipation effect. The air flow direction is to enter from the top of the heat dissipation channel 3 and flow out from the side of the protective cover 2. Under the premise of ensuring the dustproof effect, the working temperature environment of the device can be guaranteed, and the service life of the device can be improved.

Abstract

The invention discloses a safety tunnel lighting device. the safety tunnel lighting device includes a cuboid-shaped lamp body, the inner part of the lamp body is provided with an inner cavity, the topof the inner cavity is provided with a condensing surface, a plurality of lamp beads are mounted on the top center of the inner cavity, the bottom of the inner cavity is provided with flat glass layer, the top face of the lamp body is provided with a controller which is electrically connected with the lamp beads, and the controller is connected with a power supply system through a circuit; and the outer side of the lamp body is sleeved with a protective cover, a U-shaped heat dissipation channel is arranged between the inner side of the protective cover and the outer wall of the lamp body, and sliding grooves are correspondingly formed in the top ends of both sides of the protective cover. According to the safety tunnel lighting device, by arranging the protective cover, effective protection can be provided for the lamp body, by arranging the heat dissipation channel, heat generated by the lamp body when working is dissipated to avoid equipment damage caused by overheating, and at thesame time, by arranging a sliding filter net, both ends of the heat dissipation channel are shielded to avoid the entry of dust, so that the possible ray of light shielding caused by dust accumulation is avoided.

Description

technical field [0001] The invention relates to municipal facilities, in particular to a safety tunnel lighting device. Background technique [0002] Lighting equipment is an indispensable equipment in our life. In some special places, lighting equipment needs to be used 24 hours a day, especially when lighting in tunnels, long-term continuous lighting is required. Tunnel lighting can improve the road conditions in the tunnel, improve the visual enjoyment in the tunnel, reduce driver fatigue, and help improve the tunnel capacity and ensure traffic safety. [0003] Since the tunnel lighting facilities need to work continuously, the working environment is continuously high temperature, but the burden brought by the continuous high temperature to electrical equipment cannot be ignored, such as the aging of the circuit, and even the possibility of short circuit and fire hazard caused by high temperature Sex also increases geometrically.
