Description
Technical field
The utility model relates to the energy-saving illumination technical field, and refering in particular to is a kind of railway signal lighting device that adopts led light source.
Background technology
Railway signal lamp is the important component part of railway safety system, and it is being brought into play is the important function that train guides and identifies.At present, the China railways traffic lights mostly adopt is conventional light source such as incandescent lamp, and it is low that this conventional light source has a cost, advantage such as be simple and easy to change, but its shortcoming is also very obvious, and the incandescent lamp illumination effect is not high, and service life is short, and power consumption is high.And led light source is as the novel green illuminating product, and it is long to have a life-span, and advantage such as low in energy consumption is well suited for the light source as railway signal lamp.Occurred a large amount of LED railway signal lamps in recent years on the market, but the ubiquity caloric value is big, the damaged condition of being struck by lightning often occurs.Therefore, need a kind of good heat dissipation effect of design, response speed is fast, shock resistance, the LED railway signal lamp of anti-thunderbolt.
The utility model content
The technical problem that the utility model will solve is the deficiency that overcomes existing railway signal lamp, provides a kind of luminous efficiency high, shock resistance, the LED railway signal lamp of anti-thunderbolt.
For solving the problems of the technologies described above, a kind of LED railway signal lamp of the utility model comprises led light source, lamp box; Power supply, lampshade, circuit board; It is characterized in that led light source is installed on the circuit board, the light-emitting window of led light source is equipped with optical lens, and the rear portion of lamp box is equipped with the glass collar.
As the further improvement of technique scheme, described a kind of LED railway signal lamp is characterized in that the joint of lamp box and glass collar is equipped with seal washer.
As the further improvement of technique scheme, described a kind of LED railway signal lamp is characterized in that lightning protection device is installed in the lamp box, and with led light source, circuit board, power supply are installed in the lightning protection device, and lightning protection device adopts ceramic ectosome.
The beneficial effect of the utility model:
Install simply, easy to use, reliability is high.Advantages such as the employing led light source has the luminous efficiency height as the light source of railway signal lamp, and is low in energy consumption, and response speed is fast.In the LED railway signal lamp, lightning protection device is installed, can strengthens its impact resistance and anti-thunderbolt property.
Description of drawings
Fig. 1 is a kind of structural representation of LED railway signal lamp
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of LED railway signal lamp of the utility model comprises led light source 1, lamp box 2, power supply 3; Lampshade 4, circuit board 5 is in concrete installation process; Led light source 1 is installed on the circuit board 5, and the light-emitting window of led light source 1 is equipped with optical lens 6, and the rear portion of lamp box 2 is equipped with glass collar 7.The joint of lamp box 2 and glass collar 7 is equipped with seal washer.
Foregoing is merely the utility model optimum implementation, is not the specific embodiment that is used for limiting the utility model.Therefore, all modification and conversion of carrying out according to the main inventive concept of the utility model all drop within the novel protection domain of this realization.
