Abstract
In the bulb cassette in the related art, a mounting fixture can be prevented from coming off a case. However, when a space in the case for accommodating a light bulb is small, there arises a problem such that a wall surface which defines the space is thermally deformed by heat from the light bulb, and hence the product value is lowered, and in the worst case, the entire case may become unusable due to thermal deformation of the wall surface. In a case in which a case formed of resin material having low thermal resistant property such as polypropylene and a wall surface which is in the proximity with a light bulb built in the case exist, a bulb cassette for mounting the light bulb in the case is formed of thermal resistant resin, and a heat shield wall interposed between the light bulb and the wall surface is formed so as to continue from the bulb cassette.

THERMAL INSULATION STRUCTURE FOR VEHICLE ROOM LAMP
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to a vehicle room lamp to be mounted to an inner lining of a vehicle roof and, more specifically, to a thermal insulation structure of a vehicle room lamp for preventing a case from becoming damaged by heat from a light bulb stored in the case of the room lamp.
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to a vehicle room lamp to be mounted to an inner lining of a vehicle roof and, more specifically, to a thermal insulation structure of a vehicle room lamp for preventing a case from becoming damaged by heat from a light bulb stored in the case of the room lamp.
2. Description of the Related Art In manufacture of a vehicle room lamp, polypropylene which is low in cost has been employed as a case material for reducing the cost. When a light bulb with high heat value is used in such a case, there was a problem such that a terminal strip for mounting the light bulb to the case is heated by heat from the light bulb, or portion of the case where the terminal strip is to be mounted is thermally deformed (melted) by direct heat irradiation from the light bulb, whereby the terminal strip comes apart from the case.
Therefore, in order to solve such a problem, there is a technique disclosed in Japanese Unexamined Utility Model Registration Application Publication No. 4-5082. This technique is such that a terminal strip for a light bulb is mounted to a bulb cassette formed of expensive resin having high thermal resistant property, and the bulb cassette is detachably mounted to the case. In this structure, the terminal strip is prevented from coming apart by thermal deformation caused by the light bulb thereby becoming a state in which the lamp cannot be lit.
In the bulb cassette in the related art as described above, it is possible to prevent the mounting fixture from coming off the case due to thermal deformation. However, when a space in the case for accommodating the light bulb is small, there arises a problem such that a wall surface which defines the space is thermally deformed by heat from the light bulb, whereby the product value is lowered, and in the worst case, the entire case may become unusable due to thermal deformation of the wall surface.
SUMMARY OF THE INVENTION
In order to solve the above-described problem, it is an object of the invention to provide a thermal insulation structure of a vehicle room lamp in which a heat shield wall is formed between the wall surface of the case and the light bulb so as to continue from the bulb cassette, and heat from the light bulb is shielded to prevent high heat from being transmitted to the case wall surface whereby thermal deformation of the case wall surface is prevented.

Although the structure in which the single heat shield wall 5a is formed in the bulb cassette 5 for preventing thermal deformation of the single wall surface la in the embodiment described above, it is also possible to form two of the heat shield wall 5a as shown in Fig. 6 to prevent thermal deformation of the two wall surfaces opposed to each other with the intermediary of the light bulb 7.
The projection 8a formed on the insulating member 8 is not necessarily required to be a rod-shape as shown in Fig.
5A, but may be a projection 8b formed to have an acute-angled distal end and a constriction at a midsection thereof.
With the projection 8b in this structure, since the distal end is acute-angled, insertion into the portion where the bus bars 4 are cut and bent upward is facilitated and, in the inserted state, since the constriction at the midsection thereof is engaged with the cut and bent upward distal end of the bus bar 4, fixation of the insulating member 8 is ensured, and hence the securement of the insulating member 8 is further enhanced.
