Description
Technical field
The utility model is related to field of light fittings, more particularly to a kind of Tunnel Lamp.
Background technology
Expanded with the extension of expressway and through street road network, traffic becomes more unimpeded, and the tunnel in mountain and seabed is got over
Come more, traditional tunnel illumination is mainly using high pressure sodium lamp or Halogen lamp LED etc., and it has following defect in use：Electric light turns
Change efficiency low and cause that energy consumption is big, service life is short, dazzle is serious, maintenance workload is big and pollution easily is produced to environment.LED
Light fixture has the advantages that brightness big, long lifespan and low in energy consumption, traditional sodium vapor lamp and Halogen lamp LED have gradually been substituted and applied to tunnel
In illumination.But LED and its heat dissipation capacity of drive circuit are very big, if these heats do not discharge in time, electricity can be caused
The problems such as source damage, the luminosity of light fixture and life-span drastically decline, therefore radiating is a short slab for restricting LED lamp performance.
It is stuffy in tunnel and Tunnel Lamp is more special by the environment that it is worked, entrainment of many dust and particle, Tunnel Lamp
Radiator easily cause the decline of heat dispersion because substantial amounts of dust is adsorbed, it is impossible to meet the radiating requirements of light fixture.And
The setting height(from bottom) of Tunnel Lamp is high, difficult in maintenance, and attendant is difficult in time and efficiently enter the laying dust of Tunnel Lamp radiator
Row is maked an inspection tour and removed, if inspection interval is too short, not only working strength is big, also easily causes to block up because excessively continually taking track
Car phenomenon, if inspection interval is long, because the dust concentration and humidity in tunnel are always being continually changing, Tunnel Lamp is likely to place
In the working condition of " inferior health ", until Tunnel Lamp breaks down and damaged, maintainer could have found and change corresponding tunnel
Road lamp.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art that there is provided a kind of Tunnel Lamp.
To achieve the above object, the utility model uses following technical scheme：
A kind of Tunnel Lamp, including lamp housing, the radiator above lamp housing and power supply module, the extension that is hinged on lamp housing
Frame, the light source board for being fixed on envelope inner wall, the heat-conduction electric insulation being fixed between light source board and envelope inner wall layer and by lamp housing
Sealed lampshade, the light source board includes the first light source board and secondary light source plate, and the size of the first light source board is more than secondary light source
It is furnished with the first wick for sending white light or gold-tinted, secondary light source plate and is furnished with for sending feux rouges on plate, the first light source board
The second wick, after the input of second wick is connected with negative tempperature coefficient thermistor and be connected in the power supply module
Output end.
Further, the input of first wick is connected in parallel on the power supply after being connected with semistor
The output end of module.
Further, the power supply module includes voltage stabilizing current-limiting circuit, reduction voltage circuit, rectification circuit and filter circuit,
Input power is successively that first wick and the second wick are powered after voltage stabilizing, decompression, rectification and filtering.
After adopting the above technical scheme, the utility model is compared with background technology, have the following advantages that：
1st, the first light source board and secondary light source plate are provided with, the first light source board is used for the normal illumination in tunnel, secondary light source
Plate is used to send warning light, when radiator laying dust phenomenon is serious, and the temperature of light source board rises, negative tempperature coefficient thermistor
Resistance declines, and the current supply circuit of secondary light source plate is switched on, and sends the radiator product that red light reminds tour personnel's Tunnel Lamp
Dirt is serious, should clear up in time；
2nd, when the temperature of light source board is further up, the resistance value rise of semistor, the first light source
The current supply circuit of plate is cut off, and the first wick extinguishes, with prevent wick from damaging and lamp temperatures it is further up；
3rd, when the first light source board does not light, and secondary light source plate is luminous, and maintenance personal is that can conclude that it is that radiator laying dust is tight
Weight, the laying dust of radiator can be quickly removed using the comb matched with radiator tooth form；When two light source boards are not sent out
Light time, you can preliminary to conclude that Tunnel Lamp is damaged, maintenance should be removed, the maintenance difficulties of light fixture are reduced.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
Embodiment
As shown in Figures 1 and 2, a kind of Tunnel Lamp, including lamp housing 1, radiator 2 and power supply mould installed in the top of lamp housing 1
Group 3, the hanger 4 that is hinged on lamp housing 1, be fixed on the light source board 5 of the inwall of lamp housing 1, be fixed on light source board 5 and the inwall of lamp housing 1 it
Between heat-conduction electric insulation layer 6 and by the sealed lampshade 7 of lamp housing 1.Lamp housing 1 is made of the aluminium alloy with high-termal conductivity, light
The heat of source plate 5 is guided to lamp housing and radiator through the conductive insulating barrier 6 with high-termal conductivity and distributed.Each scale of radiator 2
End be made it is tip-shape to realize sophisticated heat release, during installation, the groove direction of each scale of radiator 2 is consistent with the trend in tunnel,
To accelerate distributing for heat.
As shown in Fig. 2 light source board 5 includes the first light source board 51 and secondary light source plate 52, the size of the first light source board 51 is big
In being furnished with the first wick 511 for sending white light or gold-tinted on secondary light source plate 52, the first light source board 51, to meet tunnel
