Description

This invention relates to lighting technology, and more specifically to fog lamps. The purpose of the invention is to improve the light distribution. Figure 1 shows the fog lamp, a general view; - on Figure 2 - the same, side view; fig.Z - headlight, section along the longitudinal axis; FIG. 4 shows the headlamp of the headlight to the vehicle electrical system; FIG. 5-15, the nature of the light distribution in different operating modes. The fog light (Figures 1-3) contains a housing divided in a longitudinal axis, consisting of two parts: the upper 1 and lower 2, mounted with screws 3 and 4. On the lower part 2 of the housing there is a headlight attachment unit 5 to the vehicle. An optical element is formed in the housing of the headlight; it is formed by a diffuser 6 with transparent back surfaces 7 and 8 and a reflector made in the form of two parabolic cylindrical surfaces 9 and 10, one-sidedly closed by elements of identical paraboloids 11 and 12, the focus of which is installed in adapters 13 and 14 sources 15 and 16 of the world. At the same time, the focal distances of the elements of paraboloids are equal to the distance from the top of the parabola to the focal line of the elements of parabolic cylinders 11 and 12. The reflector with sources 15 and 16 of light is pressed to the lens 6 and to parts 1 and 2 of the body with flat elastic springs 17 and 18, placed in the slots of the housing formed by the ribs 19-22. When two headlamps are installed (figure 4), as required by the traffic safety rules, the sources 15, 16, 23 and 2 lights are connected to the vehicle’s on-board network through a switch of 25 modes with eleven fixed positions. The fog light operates as follows. When two light sources 15 50 and 16 are switched on, the central part of the light distribution is provided by the elements of paraboloids 11 and 12, and the horizontal plane sweeps are due to the linear forming -55 parabolic cylindrical surfaces 9 and 10. At the same time, the transparent side surfaces 7 and 8 the diffusor cause the transmission of the reflected and direct radiation. Depending on the density of fog and the geometry of the road, setting the switch 25 modes to the appropriate position, the driver chooses the optimum light conditions for the weather conditions of the system from (headlights, switch appropriate, filaments of light sources 15, 16, 23 and 24. Works of light sources 15, 16, 23 and 24: 1. In low and medium density fogs on broadband roads with a meteorological visibility range (MDV) of 200-400 m. (Switch 25 is set to position 26). Sources 15, 16, 23 and 24 lights are included. The light distribution pattern is shown in FIG. 2. In low-density fogs with an MDW of 400 m when performing left turns. Switch 25 is set to position 27. Light sources 15, 16 and 23 are turned on. The pattern of distribution is shown in Figs. 6, 3. In low-density fogs with an MDW of 400 m when performing right turns. Switch 25 is set to position 28. Light sources 16, 23 and 24 are on. The pattern of light distribution is shown in FIG. 4. In the mist of average density with DVA 200-300 m when performing left turns. Switch 25 is set to position 29. Light sources 15, 16 and 24 are on. The pattern of light distribution is shown in FIG. 5. In mists of average density of MDV at 200-300 m when performing right turns. Switch 25 is set to position 30. Light sources 15, 23 and 24 are turned on. The pattern of light distribution is shown in FIG. 6. In high and medium density fogs with one-way traffic on vehicles with right-hand drive when DVA is 100–200 m. Switch 25 is set to position 31. Sources 15 and 16 of the light are on. The pattern of light distribution is shown in FIG. 7. In high and medium density fogs with DVA 100-200 m when performing left turns. Switch 25 is set to position 32. Sources 15 and 23 are on. The pattern of light distribution is shown in Fig. I1. 8. In high-density fogs with DVA up to 100 m on winding roads. Switch 25 is set to position 33. Light sources 15 and 24 are turned on. The pattern of light distribution is shown in Fig. 12. 9. In fogs of high and medium density with DVA 100–200 m in one-way traffic on vehicles with left-hand steering. Switch 25 is set to position 34 134 Light sources 23 and 24 are on. The light distribution pattern is shown in FIG. 10. In high and medium density fogs with DVA 100–200 m when making right turns. The switch 25 is set to position 35. The sources 16 and 24 of the light are on. The pattern of light distribution is shown in FIG. 11.B high density fogs with DVA up to 100 m on narrow single-lane roads. Switch 25 is set to position 36. Light sources 16 and 25 are turned on. The pattern of light distribution is shown in FIG.
