Energy-saving dimming device based on tunnel use

Technical Field

The utility model relates to a lamps and lanterns lighting technology field, in particular to energy-conserving dimming device based on tunnel is used.

Background

Tunnels are a form of human use of underground space as an engineering building buried in the ground. Because light is not enough in the tunnel, after the driver gets into the tunnel, the sight can receive the influence, so for the illumination tunnel, satisfy the user demand of driving, can use more tunnel lamp. At present, a sodium lamp or a metal halide lamp is generally used as a light source of a tunnel lamp, the sodium lamp is applied in a large scale due to high visual lighting effect (up to 120 lm/w), and the sodium lamp can generate heat during lighting, if the sodium lamp does not dissipate heat of the lamp, the lighting effect of the lamp can be affected, and a circuit can be burnt out due to short circuit in severe cases, so that the lamp is damaged.

For example, chinese patent that is CN216480452U in the grant bulletin number discloses a tunnel lamp that heat dispersion is good, the tunnel lamp body includes the lamp stand, the lamp stand upper surface is provided with the shell, fixing device includes the solid fixed cylinder, two the solid fixed cylinder sets up two surfaces around the shell relatively, just be provided with the spring in the solid fixed cylinder, the spring outer end is connected with the reference column, the shell outside is provided with the fixed bolster, just the locating hole has all been seted up to two surface downside around the fixed bolster, the reference column cooperatees each other with the locating hole, heat abstractor includes the heat-conducting plate, the heat-conducting plate sets up at the lamp stand upper surface, just surface mounting has a plurality of radiating fin on the heat-conducting plate, first radiator fan is all installed on two surfaces about the shell, second radiator fan is all installed to the shell upper surface left and right sides, install temperature sensor between the second radiator fan.

Use radiating fin and first heat dissipation fan and second heat dissipation fan to dispel the heat to lamps and lanterns among the above-mentioned scheme, but use a plurality of fans in the above-mentioned structure when dispelling the heat, need use more electric power to drive first heat dissipation fan and second heat dissipation fan and move, consumed more electric power among the intangible, simultaneously because the fan is more, increased the degree of difficulty when the assembly of earlier stage to and increase the time of maintenance when the later stage is to the maintenance of fan.
