Abstract

The utility model discloses an enhancement thick ring Fresnel lens colour lamp annunciator, which is composed of a casing, a reflective mirror, light source, a seat frame, a thick ring Fresnel lens, false display resistance snow and ice prevention glass, an appentice, etc., wherein, an optical system is composed of the thick ring Fresnel lens, the false display resistance snow and ice prevention glass which is arranged in front of the Fresnel lens, and the reflective mirror arranged behind the light source. The utility model has the advantages that light receiving area and the intensity of light source are relatively increased on the basis of meeting the original technical requirements; the distance for displaying is be markedly increased; the structure is simple; the installation and the modulation are convenient. The utility model has an outstanding practical value on reforming hundreds of thousands of high-post and short-post annunciators on the existing railways.

Description

Enhancement mode is slightly encircled the Fresnel Lenses light signal

The utility model belongs to a kind of ground control's equipment, particularly a kind of light signal that is used for railway, highway, navigation and the demonstration of air traffic ground signal.

A large amount of hundreds thousand of telesemes that use on the present railway of China all use thick ring Fresnel Lenses light signal (as shown in Figure 4).Its advantage is that the processing of lens is relatively easy, and technology is simple, yield rate height, low cost; Shortcoming is to use Fresnel Lenses merely, and the lens light-receiving area is few, and the efficiency of light energy utilization is low, thereby range of a signal is nearer, more and more the raising of incompatibility railways train operation speed.The New X SZ combined type teleseme that has also adopted recent years a kind of Shenyang Railway Signal Factory to produce on the railway, its lens are aspheric mirror (as shown in Figure 5), display effect is fine, but aspheric mirror is made difficulty, cost is high, is difficult for promoting.

The purpose of this utility model is by transforming existing thick ring Fresnel Lenses, increase its light-receiving area and anti-false Presentation Function, a kind of efficiency of light energy utilization height, range of a signal thick ring Fresnel Lenses light signal far away being provided.

For achieving the above object, the technical scheme that the utility model is taked is: this enhancement mode slightly encircle the Fresnel Lenses light signal by housing, reflective mirror, light source, mounting, slightly encircle Fresnel Lenses, anti-false anti-ice and snow glass and the penthouses etc. of showing are formed, and it is characterized in that the anti-false reflective mirror of installing behind anti-ice and snow glass and the light source that shows that its optical system is installed previously by thick ring Fresnel Lenses, these lens forms.

Above-mentioned anti-false the show installation that is inclined upwardly when being used for high signal of anti-ice and snow glass, downward-sloping installation when being used for dwarfsignal.Should anti-false show that anti-ice and snow glass is to inlay at the edge of glass or be coated with electric heating material, led to power lead.

The characteristics that this enhancement mode is slightly encircled the Fresnel Lenses light signal are to add reflective mirror and the anti-false anti-ice and snow glass that shows in thick ring Fresnel Lenses, light-receiving area, the intensity of light source increase relatively on basis of original technical requirement satisfying to make it, range of a signal obviously increases, and it also has advantages such as simple in structure, Installation and Debugging are convenient, has outstanding practical value to transforming hundreds thousand of the Gao Zhu, the dwarfsignal that use on the existing railway.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the utility model high signal structural representation;

Fig. 2 is the utility model dwarfsignal structural representation;

Fig. 3 is the anti-false anti-ice and snow glass structure synoptic diagram that shows;

Fig. 4 is a large amount of teleseme structural representations that use on the present railway;

Fig. 5 is the Shenyang XSZ of a signal factory combined type non-spherical lens teleseme structural representation.

Fig. 1 is to Figure 3 shows that the utility model is applied to the embodiment of high post and dwarfsignal.By housing 1, reflective mirror 2, bulb 3, lamp socket 4, slightly encircle Fresnel Lenses 5, anti-false anti-ice and snow glass 6 and the penthouses 7 etc. of showing constitute.Wherein the anti-false reflective mirror 2 that shows that anti-ice and snow glass 6 and bulb 3 backs are installed installed previously by thick ring Fresnel Lenses 5, these lens of optical system is formed.When bulb 3 was luminous, a light part of sending was directly injected thick ring Fresnel Lenses 5, and another part enters thick ring Fresnel Lenses 5 after by reflective mirror 2 reflections, invests rail track and driver's observation space, to show train signal.

Anti-false demonstration the in the utility model prevents that ice and snow glass 6 is the high-quality flat glass, and the edge is coated with electric heating material 8, leads to power lead 9, is used to melt the ice and snow that covers glass surface in the winter time after the energized.The anti-ice and snow glass 6 of the anti-false demonstration of high signal is inclined upwardly during installation, and dwarfsignal is downward-sloping, and the light of extraneous directive teleseme is reflexed on the penthouse 7 of black, thereby avoids because extraneous light is injected the teleseme back reflection and gone out false shows signal.

Claims

1. an enhancement mode is slightly encircled the Fresnel Lenses light signal, it is by housing (1), reflective mirror (2), light source (3), mounting (4), slightly encircle Fresnel Lenses (5), anti-false anti-ice and snow glass (6) and the penthouse formations such as (7) of showing, it is characterized in that the anti-false reflective mirror (2) of anti-ice and snow glass (6) and the installation of light source (3) back that shows that optical system is installed previously by thick ring Fresnel Lenses (5), these lens (5) forms.

2. enhancement mode according to claim 1 is slightly encircled the Fresnel Lenses light signal, it is characterized in that the above-mentioned anti-false anti-ice and snow glass (6) that shows, this glass (6) installation that is inclined upwardly when being used for high signal; When being used for dwarfsignal, the downward-sloping installation of this glass (6).

3. enhancement mode according to claim 1 and 2 is slightly encircled the Fresnel Lenses light signal, it is characterized in that above-mentionedly anti-ly false showing that anti-ice and snow glass (6) is to inlay at the edge of glass or be coated with electric heating material (8), leads to power lead (9).
