Further, the invention according to claim 4 is such that the lamp is a light emitting diode.

  In the invention according to claim 1, since the light of the second lamp serving as the light source of the indirect illumination unit is reflected by the ceiling member and then indirectly irradiated to the vehicle compartment side through the transparent lens unit of the base member. There is no need for conventional shields or reflectors made of different members, the number of parts can be reduced, and each lamp is assembled on the base member side, so that the assembly is greatly improved. it can.

In the invention according to claim 2, a transparent lens portion and a light shielding treatment are applied to the base member to form a non-transparent light shielding portion at a simple and arbitrary location. Since the transparent semi-light-shielding part can be easily and arbitrarily formed, the light can be freely produced and the atmosphere in the vehicle interior can be improved.
Further, in the invention according to claim 4, by using the light emitting diode for the lamp, it is possible to reduce the load on the battery with power saving, and it is not necessary to install a service hole for maintenance and the structure can be simplified. it can.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
The drawings show, as an example, a case where the present invention is applied to an interior light of an automobile, FIG. 1 is an overall front view, FIG. 2 is an overall perspective view, and FIG. 3 is a perspective view showing a state of being assembled indoors. 4 is a cross-sectional view taken along line AA of FIG. 1, FIG. 5 is a cross-sectional view taken along line BB of FIG. 1, and FIG. 6 is a cross-sectional view taken along line CC of FIG.
1 and 2, 1 is a base member, 2 is a direct illumination unit that directly irradiates light of a lamp such as a map lamp, and 3 is light of the lamp so as to be lit up in a calm atmosphere etc. This is an indirect illumination unit that indirectly illuminates. Reference numeral 4 denotes a switch for turning the direct illumination unit 2 and the indirect illumination unit 3 on and off. Reference numeral 5 denotes a sensor for automatically adjusting, for example, brightness and color of the indirect illumination unit 3.

In the present invention, as shown in FIG. 4, a first lamp 6 a serving as a light source of the direct illumination unit 2 and a second lamp 6 b serving as a light source of the indirect illumination unit 3 are assembled to the base member 1. The light from the second lamp 6b is reflected on the ceiling member 7 and then indirectly irradiated to the passenger compartment side through the transparent lens portion of the base member 1.
That is, as a structure for obtaining indirect light in the prior art, a separate reflector that also serves as a casing is provided above the second lamp, and the indirect light is reflected by reflecting the light of the second lamp against the reflector. On the other hand, in the present invention, by reflecting on the ceiling member 7, the reflector (or casing) is not required, the number of components is small, the installation space is small, and each lamp 2, 3 is provided on the base member 1 side. Therefore, the assembly workability is excellent.

The base member 1 is formed with a transparent lens portion 8 and a non-transparent light-shielding portion 9 subjected to a light-shielding process. As shown in FIGS. 5 and 6, the lens portion 8 is a portion for guiding the direct light of the first lamp 6a and the indirect light of the second lamp 6b to the inside of the vehicle, and the light shielding portion 9 is a lamp or harness. It is for concealing etc. and exhibiting a design effect.

In this case, when the second lamp 6b is not lit, when viewed from the indoor side, it has a dark color tone like the light-shielding portion 9 and the inside is not visible at all. However, when the second lamp 6b is lit, The pattern can be raised by transmitting light thinly. In particular, when the semi-light-shielding portion 10 is formed in the light-shielding portion 9, the pattern of the light-shielding portion 9 is completely different between when the second lamp 6b is turned off and when it is turned on, and an excellent design effect can be exhibited. Become.
In the case of FIG. 5, the semi-light-shielding part 10 is formed in a track shape on the outer periphery of the light-shielding part 9, and is tripled in the light-shielding part 9 when the second lamp 6b is turned on. The ring is configured to float slightly.

  The lamp preferably uses a light emitting diode. Light emitting diodes have abundant colors and can produce illumination of any color, and have the advantage of reducing power consumption and reducing the load on the battery. In addition, it can be used semi-permanently without breaking the ball, and since the amount of heat generated is small, there is no contamination of the ceiling due to air convection, so installation of a service hall etc. for maintenance work is unnecessary, The structure as an interior light can be greatly simplified.

  As shown in FIG. 3, the vehicle interior lamp of the present invention configured in this way is assembled to the ceiling member 7 for use, but a conventional reflector (or casing) is completely used. Since it is unnecessary and can be directly assembled to the ceiling member 7 having a shallow concave shape, the installation space is small and the assembling work can be easily performed.
