摘要:
An inclination angle measurement apparatus includes a first ultrasonic sensor (3) for sending an ultrasonic wave toward a road surface (2), second and third ultrasonic sensors (4 and 5) each for receiving an ultrasonic wave reflected from the road surface (2), and a calculation control circuit (14) for calculating an angle of inclination of a vehicle with respect to the road surface (2) based on a phase difference between ultrasonic waves received by the second and third ultrasonic sensors (4 and 5). Thus the inclination angle measurement apparatus can accurately measure the angle of inclination of the vehicle with respect to the road surface (2).

In an LED2 having a directionality in an emission direction of emitted light, light emitted from a light emitting surface of the LED 2 is refracted by a semi-cylindrical concave lens 3 to be enlarged in the circumference direction of an optical axis of a headlight 1; thus, even when the LED2 is applied to a headlight that is constituted by optical members that are similar to optical members that are compatible with conventional light sources having no directionality, such as an incandescent lamp, a discharge lamp and the like, it can be used as a light source for headlight that is capable of illuminating the right and left directions ahead of a vehicle with a sufficient brightness.

A through hole that is slightly larger than a size of a rear end of a transformer container is formed in a rear cover constituting a part of an external wall of a starting circuit unit. The transformer container houses therein a transformer and constitutes a transformer portion. The transformer portion is assembled such that a rear end of the transformer container projects from the through hole. This allows the transformer container to constitute a part of the external wall of the starting circuit unit.

An electric discharge lamp lighting device wherein a high voltage generating transformer 10 comprises a secondary coil 13 wound on an outer side of a laminated core 12 disposed in the center of a bobbin 11 and a primary coil 14 wound on an outer side of said secondary coil 13. A high voltage output terminal 13a of said secondary coil 13 is connected to a high voltage terminal of an HID lamp through a terminal 12a of a laminated core 12. A low voltage input terminal 13b of said secondary coil 13 is connected to a primary coil 14. As a result, insulation volume can be reduced and a reduction in the size of the device can be achieved.

A shielding wire is provided with a first conductor, a shield for sheathing the first conductor through an insulating member, and a second conductor which is in contact with the shield. Therefore, a troublesome step of unknitting the braid of the shield is eliminated, and the work is done at a higher efficiency and the manufacturing cost is reduced.

In a projector-type headlight in which a light-emitting face of an LED 1 is placed perpendicular to an optical axis so that light emitted by the LED 1 is projected ahead of a vehicle through a convex lens 2, the light-emitting face is placed upward from the optical axis of the headlight, and a lower edge side 1a of the light-emitting face is formed into a linear shape and is placed on the optical axis, and a reflection face 3a is placed in a plane formed by the optical axis and the linear-shape edge side 1a of the LED 1 to thereby combine direct light emitted by the LED 1 and reflection light reflected on the reflection face 3a, so that an intensity of light emitted in a direction normal to the light-emitting face from the edge side 1a is enhanced.
