Embodiment 1

[0043] A carpet lamp such as Figure 5-13 As shown, obliquely illuminates the object surface 106 to form a projection pattern 109. The projection pattern includes a near lamp end 101 and a far lamp end 102. The carpet lamp includes a light source assembly 1, a condenser lens assembly 2, a deflection lens assembly 3, and a film assembly 4. and the imaging assembly 5; the condenser lens assembly 2 is arranged downstream of the optical path of the light source assembly 1, the deflecting lens assembly 3 is arranged downstream of the optical path of the condenser lens assembly 2, the film assembly 4 is arranged downstream of the optical path of the deflecting lens assembly 3, and the imaging The assembly 5 is arranged downstream of the optical path of the film assembly 4; the deflecting lens assembly 3 deflects the light passing through the condenser lens assembly 2 to a preset deflection direction, and the deflection angle of the light increases gradually according to the preset de...

Embodiment 2

[0063] A vehicle includes the carpet lamp as described in the above embodiments.

[0064] Of course, in practical situations, the carpet lamp of the present invention can also be used in road lighting or commercial advertisements or carpet lamps, so as to obtain uniformly illuminated light spots.

Abstract

The invention discloses a carpet lamp and a vehicle. The carpet lamp is obliquely illuminated on the surface of an object to form a projection pattern. The projection pattern includes a near lamp end and a far lamp end, and includes a light source assembly, a condensing lens assembly, a deflecting lens assembly, a film assembly and a Imaging assembly; the condenser lens assembly is arranged downstream of the optical path of the light source assembly, the deflecting lens assembly is arranged downstream of the optical path of the condensing lens assembly, the film assembly is arranged downstream of the optical path of the deflecting lens assembly, and the imaging assembly is arranged downstream of the optical path of the film assembly The deflection lens assembly deflects the light passing through the condenser lens assembly to the preset deflection direction, the deflection angle of the light gradually increases according to the preset deflection direction, and part of the light is deflected out of the film assembly to receive the light Outside the range; the deflection of the light by the deflecting lens assembly makes the projection pattern closer to the near-lamp end, the greater the reduction in illuminance. After adding the deflecting lens component, the projection pattern produced by the present invention has good uniformity and high definition.

Description

technical field [0001] The invention relates to the technical field of projection, in particular to a carpet lamp and a vehicle. Background technique [0002] As the application of car carpet lights becomes more popular, car manufacturers and consumers have higher and higher requirements for car carpet lights, requiring carpet lights to be able to project larger patterns (such as 2m long), but there are also some defects when the pattern is too large . Due to space or installation constraints, to obtain large-scale patterns, the projected pattern on the ground can only be formed by oblique projection. The angle between the optical axis and the ground is small (such as 30°), so the projection pattern has the problem of uneven illumination of the pattern with high brightness at the near end and low brightness at the far end. see attached Figure 1-4 ,like figure 1 A traditional carpet lamp as shown, along the direction of the optical axis, sequentially includes: a light so...
