Abstract
The utility model discloses a tunnel lighting device, which relates to the technical field of tunnel engineering equipment. The tunnel lighting device comprises a light intensity detection instrument for acquiring the light intensity of the light inside and outside a tunnel, a lighting controller for automatically controlling a switch of each lighting loop by the light intensity detection instrument and tunnel lamps connected in each lighting loop, wherein the tunnel lamps comprise light adjusting lamps and non light adjusting lamps which are alternatively distributed; the output end of the lighting controller is respectively connected with one light adjusting lamp control branch and one non light adjusting lamp control branch. Compared with the prior art, the tunnel lighting device solves the problems of the existing tunnel lighting system that the existing tunnel lighting system is too complex, resulting in poor reliability of equipment, too large investment of the equipment and higher maintenance cost of the equipment.
Description
Technical field
The utility model relates to Tunnel Engineering corollary equipment manufacturing technology field, especially a kind of lighting device.
Background technology
Tunnel illumination is the basic guarantee of vcehicular tunnel traffic safety, occupies critical role in vcehicular tunnel construction and supervisory control system.Simultaneously, tunnel illuminating system is again high energy consumption system in the vcehicular tunnel, and huge to the consumption of electric energy, electric cost occupies very large proportion in the vcehicular tunnel operation cost.Therefore, the research of tunnel illumination power-saving technology had very important realistic meaning and wide application prospect.China mainly considers from the selection of illuminating lamp source, pattern of lighting, several aspects such as confession distribution system, Energy Saving Control mode and system maintenance the research of tunnel illumination power-saving technology at present, and reasonably control mode can make the tunnel illuminating system realization farthest energy-conservation, is the energy-conservation key in tunnel.
At present, both at home and abroad the tunnel illumination control mode be broadly divided into manual control mode, the sequencing control mode of carrying out at times and according to three kinds of the Automatic Control modes in the brightness value self-control lighting loop inside and outside the hole.Consider that from safety, economy, the various aspects such as energy-conservation automatic control mode is better than other two kinds of control modes, the most domestic tunnel illuminating system has all adopted automatic control mode.The tunnel illumination automatic control mode is to utilize brightness detection instrument to gather respectively the inside and outside luminance parameter in tunnel, after contrast is processed, automatically controlled the switch of each lighting loop by computer system or lighting controller. the corresponding tunnel lamp of ON/OFF adapts brightness of illumination in the hole and the brightness of extraneous natural daylight.Chinese utility model patent (patent publication No.: CN 102595679 A) discloses a kind of highway tunnel illumination energy-saving control system, this system is theoretical according to Fuzzy Neural-network Control, set up the outer brightness of vcehicular tunnel and tunnel portal, changeover portion LED Tunnel Lamp brightness relationship model, the brightness of LED Tunnel Lamp and tunnel vehicle flowrate relational model are realized the intelligent control to the brightness of LED Tunnel Lamp.Said system is almost Perfect in theory, but also exists owing to problems such as system are too complicated, and the equipment dependability that causes is not good enough, and equipment investment is excessive, and cost of equipment maintenance is higher.
The utility model content
The purpose of this utility model provides a kind of lower-cost tunnel illuminating device that can realize stepless dimming.
In order to address the above problem, the technical solution adopted in the utility model is: this tunnel illuminating device includes the luminance detector that gathers the inside and outside illuminance in tunnel, automatically control by described luminance detector each lighting loop switch lighting controller and be connected on tunnel lamp in described each lighting loop etc.Described tunnel lamp comprises dimming lamp and non-dimming lamp, and described dimming lamp and non-dimming lamp distribute alternately, and the output of described lighting controller is connected with respectively a dimming lamp control branch road and a non-dimming lamp control branch road.
In the technique scheme more specifically technical scheme can also be: the illuminance of described dimming lamp is more than or equal to the illuminance of described non-dimming lamp.
Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:
1, the utility model has been saved a large amount of equipment investment funds owing to only adopted the dimming lamp of half quantity.
2, the utility model is owing to adopt light modulation to add non-dimming mode illumination, and the reliability of equipment obviously improves.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Fig. 1, Fig. 2 and this tunnel illuminating device shown in Figure 3, include the luminance detector 41 that gathers tunnel 1 interior illuminance and the luminance detector 42 of outer illuminance, automatically control by luminance detector 41 and 42 each lighting loop switch lighting controller 2 and be connected on tunnel lamp 3 in each lighting loop etc.Tunnel lamp 3 is divided into a plurality of dimming lamps that distribute alternately 31 and non-dimming lamp 32, and the output of lighting controller 2 is connected with respectively one by branch road and the branch road by the non-dimming lamp 32 of non-dimmer switch 22 controls of dimmer switch 21 control dimming lamps 31.The illuminance of dimming lamp 31 is more than or equal to the illuminance 32 of non-dimming lamp.The control method of lighting controller 4 is as follows: when the interior required illuminance in tunnel 1 less than normal light illumination 50% the time, close all non-dimming lamps 32 by non-dimmer switch 22, only carry out light modulation by 21 pairs of dimming lamps of dimmer switch 31 and satisfy required illuminance requirement; When the interior required illuminance in tunnel 1 more than or equal to normal light illumination 50% the time, open all non-dimming lamps 32 by non-dimmer switch 22, and carry out light modulation by 21 pairs of dimming lamps of dimmer switch 31 and satisfy required illuminance requirement.Lighting controller 4 is microcomputer controllers, and dimmer switch 21 is thyristor regulating optical modules, and non-dimmer switch 22 is solid-state switch or contactor, and dimming lamp 31 is LED lamps, and non-dimming lamp 32 is common metal Halogen lamp LEDs.
Claims (2)
1. tunnel illuminating device, include the luminance detector that gathers the inside and outside illuminance in tunnel, automatically control the lighting controller and the tunnel lamp that is connected in described each lighting loop of the switch of each lighting loop by described luminance detector, it is characterized in that: described tunnel lamp comprises dimming lamp and non-dimming lamp, described dimming lamp and non-dimming lamp distribute alternately, and the output of described lighting controller is connected with respectively a dimming lamp control branch road and a non-dimming lamp control branch road.
