The structure is only provided with the touch sheet assembly and the lampshade pressing plate on the light reflecting bowl, and the structure is simple and convenient to assemble. Just the utility model discloses a middle insulating isolation region separates the touch panel subassembly for left side touch district and right side touch district, lights following two sets of light sources, can assemble left and right reading lamp, adopts two independent reading lamp structures for the tradition, arranges that the space is little, and is with low costs. Meanwhile, the left and right touch areas are convenient for blind operation. The sound transmitting plate is covered by cloth, holes of the sound transmitting plate can be enlarged, sound is blocked less, the cloth covers the holes, large holes cannot be seen, attractiveness is affected, meanwhile, different materials and colors can be selected, and grade is improved.

The present invention will be described in more detail with reference to the accompanying drawings and examples.

Detailed Description

In the embodiment, as shown in fig. 1 to 3, an automotive indoor reading lamp includes a housing 1, a circuit board 2 mounted on the housing 1, and a rear cover 10. Be provided with light source 8 on the circuit board 2, install reflector 3 on the casing 1, reflector 3 is located light source 8 directly over, still install transparent cover 4 on the casing 1, transparent cover 4 is located reflector 3's top. The structure can realize the lighting effect of the light source 8, and in order to realize touch control, and simultaneously, reduce the increase of parts and facilitate assembly, a lampshade pressing plate 5 is installed on the reflecting bowl 3, a sinking platform 31 is arranged on the upper edge of the reflecting bowl 3, the lampshade pressing plate 5 is installed on the sinking platform 31, a touch panel assembly 6 is arranged on the lampshade pressing plate 5 in a gluing way, and the transparent lampshade 4 is in contact fit with the touch panel assembly 6; a connecting lead 7 is arranged between the touch sheet assembly 6 and the circuit board 2, and a layer of indium is plated on the surface of the reflecting bowl 3, so that the reflecting bowl 3 is insulated, and the change of the touch capacitance cannot be influenced.
