Definitions

  • This invention relates to vehicle lamp assemblies of the type in which the colour of the light to be produced by the lamp cannot be readily perceived when the lamp is not illuminated. This reduces the risk that, in bright sunlight for example, the lamp assembly may appear to be illuminated, when in fact it is not.
  • a vehicle lamp assembly comprises a light source, an outer element having alternate zones of light transmission and light absorption and a lens element between the light source and the outer element having a respective lens formation for each zone of light transmission arranged to concentrate light from said source, thereon, wherein the outer element is formed of a partial-light transmissing material, so zones of light transmission comprise zones of reduced thickness compared to the zones of light absorption.
  • FIG. 1 shows a vehicle signalling lamp comprising a bulb 10 located at the focus of a parabolic reflector 12.
  • Parallel light, such as the rays 14, from the reflector 12 is directed on to a distributor plate 16 which is made of a plastics material coloured in accordance with the required colour of the light from the lamp.
  • a cover plate 18 of neutral grey plastics material.
  • the plate 18 has alternate thick zones such as the zone 20 and thin zones such as the zone 22.
  • the nature of.' the material of the cover plate 18 is such that the proportion of incident light which is transmitted by the. thin zones 22 is greater than 25% while the proportion transmitted through the thicker zones 20 is less than 15%.
  • the distributor plate 16 has lens elements such as the element 24 formed thereon and arranged to direct the collimated light from the deflector 12 on to the thin zones 22 so that when the bulb 10 is illuminated the perceived colour from the cover 18 is that of the distributor plate 16.
  • the only way in which the colour of the distributor plate 16 can be perceived is if incident light from outside -the lamp passes through the distributor plate 16 and is thence reflected out again. Only that part of the incident light which falls on the thinner zones 22 will reach the reflector at any significant level and since such light when reflected from the reflector 12 is essentially uncollimated, only about half of this light will fall on the thinner zones 22 so as to be perceivable from the outside.
  • Figure 2 illustrates a modification of the embodiment shown in figure 1 in which the cover plate 18 is replaced by a composite cover plate 30, the thicker zones 32 of which are formed of neutral grey material while the thinner zones 34 are formed of a clear plastics material.
  • the cover plate 36 comprises a layer 38 of clear plastics material with projections 40 of neutral grey material secured to one surface thereof.
  • Figure 4 illustrates another embodiment of the invention, which is similar to that of the embodiment illustrated in Figure 1 except that the projections 46 forming the thicker zones of the cover plate 48 extend outwardly and are of generally triangular cross-section. Since the neutral grey plastics material is at its thickest at the apices of the triangles, the inner surface of the cover plate is relieved at 50 so as to save material.
  • Figure 5 illustrates a modification of the embodiment shown in Figure 6 having a cover plate 52 of clear plastic material with triangular cross-section projections 54 of neutral grey plastic material on the outer thereof.
  • the cover plate 56,. is predominently of neutral grey plastics material in the interstices between the projections.
  • FIG 7 illustrates a lamp which is basically similar to the lamp illustrated in Figure 1 except that its cover plate 60 has the zones of increased thickness extended to form baffles 62 projecting almost as far as the distributor plate 16.. As before the collimated light is concentrated by the lens formations 24 on to the thinner zones 64 between the baffles 62.
  • FIGs 8 and 9 illustrate modifications to the embodiment shown in Figure 7.
  • the cover plate 70 comprises a layer 72 of clear plastics material with baffles 74 of grey plastics material mounted on the inner surface thereof.
  • the cover plate 76 is basically of grey plastics material but has clear plastic inserts 78 in the zones between the baffles 80.
  • the cover plates are of uniform cross-section, the alternate zones of differing cross-section being in the form of parallel strips.
  • the cover plates also have a similar cross-section to that illustrated in a plane perpendicular to that of the drawings, either the thicker zones or the thinner zones constituting isolated squares.
  • the parabolic reflector 12 may be replaced or supplemented by a Fresnel collimator.
