Description
Technical field
The utility model relates to LED lamp technical field, refers in particular to a kind of great power LED railway signal lamp.
Background technology
Deficiency and defectives such as everyone knows, existing railway signaling mechanism generally adopts incandescent lamp, and it has the energy consumption height, and the life-span is short, and tone is single.For effectively eliminating this deficiency and defective, many significant explorations and research have been done in the row.The LED signal lamp has also appearred now, train operation is commanded in variation by control LED light color (red, yellow, green, bluish white, orchid), the light of the different colours of signal lamp shows is representing different connotations, the engine driver shows according to the different color of signal lamp, handles stopping, open, quicken, slow down and judging current of traffic of train.Existing railway LED signal lamp generally adopts low-power LED lamp to make, and brightness is not enough, has potential safety hazard; In addition, existing railway signaling mechanism generally only adopts one group of LED as light source, and after breaking down, full lamp extinguishes, and influences the normal operation of train.So existing LED light is transformed, is necessary in fact.
The utility model content
The purpose of this utility model is intended to overcome the deficiency and the defective of prior art, and great power LED railway signal lamp a kind of simple and compact for structure, reasonable in design, safe and reliable is provided.
Technology solution of the present utility model is as follows:
A kind of great power LED railway signal lamp of the utility model, it comprises housing, is provided with power circuit in the described housing, described case top is provided with luminosity scale, luminosity scale is provided with several great power LEDs, and described several great power LEDs are divided into two groups, and every group is electrically connected with power circuit respectively.
Further, described luminosity scale top is provided with the optically focused dish by support, and optically focused dish and luminosity scale are in a parallel set; Described optically focused dish is provided with some collector lenses, and the number of locations of described collector lens is corresponding with the number of locations of great power LED; The collector lens of described position correspondence and the distance between the great power LED equal the focal length of collector lens.
Further, described several great power LEDs become to be regularly arranged on the luminosity scale.
Wherein, described collector lens is Fresnel flat thread lens.
Wherein, the power of described great power LED is 3w.
The beneficial effects of the utility model are: luminosity scale of the present utility model is provided with several great power LEDs, and described several great power LEDs are divided into two groups, and every group is electrically connected with power circuit respectively.Being the utility model is divided into two groups of main light source and secondary light sources with several great power LEDs, generally speaking, the utility model is with the luminous indication of main light source, when main light source breaks down or damages, secondary light source will light and replace secondary light source, and this replacement is realized that by control circuit it is very convenient to operate.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As Fig. 1, Fig. 2 and shown in Figure 3, the novel a kind of great power LED railway signal lamp of this reality, it comprises housing 5, is located at the luminosity scale 3 at housing 5 tops and is located at the optically focused dish 1 of luminosity scale 3 tops by support 6.Described housing 5, luminosity scale 3, support 6 and optically focused dish 1 constitute the utility model agent structure, are generally made by metal material, and the preferred aluminum alloy materials of the utility model is made.
Be provided with power circuit in the described housing 5, as the utility model control power supply.The utility model adopts in the power circuit and is provided with photo resistance, be used to detect great power LED 4, existing LED signal lamp normally detects with size of current, when the LED light emitting diode opens circuit, this mode is feasible, but electric current does not change when LED light-emitting diodes tube short circuit, just can't detect.The utility model adopts the light intensity detection method, with 4 work of photo resistance supervision great power LED, is converted into the fault that electric current is differentiated great power LED 4 with light intensity, has overcome existing LED signal lamp short trouble and can't differentiate problem.
Described luminosity scale 3 is provided with several great power LEDs 4, and described several great power LEDs 4 are divided into two groups, and every group is electrically connected with power circuit respectively.4, one groups of two groups of great power LEDs are as main light source, and one group as secondary light source, when main light source breaks down or damages, start secondary light source automatically by control circuit, have greatly improved safety coefficient.
Described optically focused dish 1 is in a parallel set with luminosity scale 3; Optically focused dish 1 is provided with some collector lenses 2, and the number of locations of described collector lens 2 is corresponding with the number of locations of great power LED 4; The collector lens 2 of described position correspondence and the distance between the great power LED equal the focal length of collector lens 2, to bring into play best spotlight effect.
Described several great power LEDs are regularly arranged on the luminosity scale 3 for 4 one-tenth.In the present embodiment, luminosity scale 3 is a disk, and luminosity scale 3 is provided with 7 great power LEDs 4, and wherein 1 great power LED 4 is located at the middle position of luminosity scale 3, and other 6 great power LEDs 4 evenly are located on the same excircle.Separately 1 LED 4 of 3 great power LEDs 4 and middle position consists of main light source on the excircle, and other 3 great power LEDs 4 of outer circumferential edge are formed secondary light sources.
