Description

  The present invention relates to a vehicle interior lighting device used by being attached to a ceiling material in a vehicle interior of a vehicle, and a vehicle interior lighting structure in which the vehicle interior lighting device is attached to a vehicle ceiling material. More specifically, the present invention improves the design of the illumination by indirect illumination using reflected light from the ceiling material, etc., and the light source cannot be directly seen, so that the vehicle interior can be given a more luxurious atmosphere. The present invention relates to a vehicle interior illumination device and a vehicle interior illumination structure in which the vehicle interior illumination device is attached to a ceiling material.

  Conventionally, in a vehicle such as a passenger car, an indoor lighting device is generally installed on the ceiling for the purpose of nighttime indoor lighting or the like. Further, in recent years, indoor lighting devices that are not merely intended for illumination in the passenger compartment but have a higher design and a more luxurious atmosphere in the passenger compartment are becoming widespread. As such an interior lighting device, rather than illuminating the interior of the vehicle with direct light, the ceiling material is irradiated with light from the light emitter, reflected on the surface of the ceiling material, and the interior of the vehicle is illuminated with this indirect light. An indirect lighting type indoor lighting device has been proposed (see, for example, Patent Document 1).

  For example, as shown in FIG. 6, the indoor lighting device 100 described in Patent Document 1 includes a recess 102 formed in a ceiling panel 101, a transparent cover-like lens 103 that covers the recess 102, and the lens 103. And a lamp 104 that irradiates the recess 102 and a light shielding film 105 that shields the interior of the lamp 104 from the vehicle interior (see FIG. 4 of Patent Document 1). The lamp 104 is provided on the lamp substrate 106, and the lamp substrate 106 is attached to the lens 103. As a result, the light from the lamp 104 is reflected by the recess 102 and then passes through the lens 103 to be irradiated into the vehicle interior. The interior of the lamp 104 is shielded from light by the light shielding film 105.

  However, in the conventional room lighting device 100 described in Patent Document 1 above, the side of the lamp 104 is not particularly shielded from light. The lamp 104 may be directly visible (see arrow A in FIG. 6). In this way, unlike the uniform light indirect light reflected from the ceiling panel 101, when the lamp itself is seen as point light with high brightness, the appearance is not good, the design is impaired, and the luxury feeling A certain atmosphere will be lost.

  The present invention has been made in view of the above-described conventional situation. By preventing the light emitting diode from being directly seen from the vehicle interior, the design of the illumination is improved, and the interior of the vehicle interior is enhanced by indirect illumination.
