Embodiment 1

[0037] Figure 1 to Figure 8 Embodiment 1 of the light source unit of the semiconductor-type light source of the vehicle lamp of the present invention and Embodiment 1 of the vehicle lamp of the present invention are shown.

[0038] (explanation of structure)

[0039] Hereinafter, the structure of the light source unit of the semiconductor-type light source of the vehicle lamp of the first embodiment and the structure of the vehicle lamp of the first embodiment will be described. exist Figure 8 Among them, reference numeral 100 is the vehicle lamp of the first embodiment.

[0040] (Description of Vehicle Lamp 100 )

[0041] In this example, the vehicle lamp 100 is a one-lamp type rear parking lamp. That is, the above-mentioned vehicle lamp 100 simultaneously functions as a tail light function as a first light function and a stop light function as a second light function with one lamp (one lamp, one lamp). The vehicle lamps 100 described above are installed on the rear le...

Embodiment 2

[0133] Figure 9 , Figure 10 The second embodiment of the light source unit of the semiconductor-type light source of the vehicle lighting device of the present invention and the second embodiment of the vehicle lighting device of the present invention are shown. in the figure, with Figure 1 to Figure 8 The same symbols indicate the same parts.

[0134] The light source unit 1 and the vehicle lamp 100 in the first embodiment above are a one-lamp type rear parking lamp. That is, in the light source unit 1 and the vehicle lamp 100 of the first embodiment described above, one lamp (one lamp, one lamp) simultaneously functions as the tail lamp function as the first lamp function and the parking lamp function as the second lamp function. That is, it is a composite function (multiple functions) lamp. In view of this, the light source unit and the vehicle lamp of the second embodiment are single-function (one-function) lamps. That is, the light source unit of the present embod...

Abstract

The invention relates to a light source unit of a semiconductor-type light source of a vehicle lighting device and a vehicle lighting device. The conventional light source unit has problems of an increasing size and radiation. According to the present invention, a direction "D" for mounting the connector 14 at a power source side to a connector portion 13 is perpendicular or substantially perpendicular with respect to a direction O-O for mounting a light source unit 1 to the vehicle light unit 100. As a result, the present invention can decrease a depth space of the light source unit and efficiently radiated heat generated by the light emitting chips 40 to 44, resistances RS, RT, RP, diodes DS, DT, and conductors 51 to 57 to an outside.

Description

technical field [0001] The present invention relates to a light source unit of a semiconductor-type light source of a vehicle lamp. In addition, the present invention relates to a vehicle lamp using a semiconductor-type light source as a light source. Background technique [0002] Conventionally, there is such a light source unit (for example, Patent Document 1 (Japanese Patent Laid-Open No. 2004-31076)). Hereinafter, a conventional light source unit will be described. In conventional light source units, LEDs, resistors, diodes, and conductors are mechanically mounted and electrically connected by upper and lower contact parts, and these are assembled in a socket housing, and a mounting part is provided in the socket housing. A conventional light source unit is detachably attached to a vehicle lamp by using an attachment portion of a socket cover. [0003] However, the conventional light source unit tends to increase in size because the LED, the resistor, and the conducto...
