ABSTRACT:
The present invention provides a lighting unit with a reflecting mirror using a bulb, in which the reflecting mirror will not fall out of a base due to vibration or deterioration of an adhesive by aging. The lighting unit includes a reflecting mirror (1) having a reflecting part (3) at one end and a neck portion (4) at another end, a bulb (11) as a light source, and a base (12). The bulb (11) is positioned inside the reflecting mirror (1). An end of the bulb (11) is inserted into the neck portion (4) of the reflecting mirror (1), and the base (12) is fixed to the neck portion (4). Thus, the bulb (11), the reflecting mirror (1), and the base (12) are combined into one component. The maximum outer diameter of the bulb (11) is larger than an inner diameter of the neck portion (4) of the reflecting mirror (1).
