Abstract

A tractor headlight device according to the present invention is configured from a pair of high-beam units and a pair of low-beam units, wherein the high-beam units and the low-beam units are respectively disposed at top and bottom. High-beam lamp lenses configuring the high-beam units are formed extending from the front to the sides of a hood. Low-beam lamp lenses configuring the low-beam units are formed along a front grill under the high-beam units.

First claim

The invention claimed is:

1. A headlight device of a tractor comprising:
a pair of high-beam units; and
a pair of low-beam units,
characterized in that
the pair of high-beam units and the pair of low-beam units are arranged respectively at upper and lower sides,
wherein each of the high-beam units comprises:
a high-beam lamp;
a high-beam lamp housing supporting the high-beam lamp; and
a high-beam lamp lens covering the high-beam lamp, and

wherein the high-beam lamp lens is formed from a front surface to a side surface of a bonnet.

2. The headlight device of the tractor according to claim 1 , wherein the high-beam lamp lens is formed so as to be projected from the side surface of the bonnet.

3. The headlight device of the tractor according to claim 2 ,
wherein each of the high-beam units further comprises:
a reflector reflecting light of the high-beam lamp; and
an inner casing covering the reflector, and

wherein the inner casing is projected from the side surface of the bonnet and formed along an inner surface of the high-beam lamp lens.

4. The headlight device of the tractor according to claim 3 , wherein glossy plating is applied to an outer surface of the inner casing opposite to the high-beam lamp lens.

5. The headlight device of the tractor according to claim 4 , wherein each of the high-beam units and each of the low-beam units are connected to each other via a bracket.

6. A tractor comprising:
the headlight device according to claim 4 ; and
a symbol mark arranged at a center of the headlight device.

7. The headlight device of the tractor according to claim 3 , wherein each of the high-beam units and each of the low-beam units are connected to each other via a bracket.

8. A tractor comprising:
the headlight device according to claim 3 ; and
a symbol mark arranged at a center of the headlight device.

9. The headlight device of the tractor according to claim 2 , wherein each of the high-beam units and each of the low-beam units are connected to each other via a bracket.

10. A tractor comprising:
the headlight device according to claim 2 ; and
a symbol mark arranged at a center of the headlight device.

11. The headlight device of the tractor according to claim 1 , wherein each of the high-beam units and the each of the low-beam units are connected to each other via a bracket.

12. A tractor comprising:
the headlight device according to claim 1 ; and
a symbol mark arranged at a center of the headlight device.

13. A headlight device of a tractor comprising:
a pair of high-beam units; and
a pair of low-beam units,
characterized in that
the pair of high-beam units and the pair of low-beam units are arranged respectively at upper and lower sides,
wherein each of the low-beam units comprises:
a low-beam lamp;
a low-beam lamp housing supporting the low-beam lamp; and
a low-beam lamp lens covering the low-beam lamp, and

wherein the low-beam lamp lens is formed along a front grill below each of the high-beam units.

14. The headlight device of the tractor according to claim 13 ,
wherein each of the low-beam units has one or more illumination lamps, and
wherein the one or more illumination lamps highlights a zone along an outline of the low-beam lamp lens.

15. The headlight device of the tractor according to claim 14 , wherein the one or more illumination lamps are turned on following turning on of a work lamp and turned off following turning off of the work lamp.
