Abstract

(57) [Abstract] [Purpose] An object of the present invention is to provide a vehicular lamp having a good appearance of the light emission range around the periphery of the lens. [Constitution] At least one of the inner lens 2 and the outer lens 3 is provided with a blind portion 5 for blocking the view of the housing 1 between the peripheral edge of the inner lens 2 and the peripheral edge of the outer lens 3. As a result, when the vehicular lamp is viewed from the front, the blindfold portion 5 blocks the housing 1 from being seen between the peripheral edge of the inner lens 2 and the peripheral edge of the outer lens 3, so that the dark portion on the outer periphery of the lamp disappears and the lens 2 and The appearance of the light emission range at the periphery of 3 is improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicular lamp having a double lens structure such as a rear combination lamp including a stop lamp, a turn signal lamp, a back lamp, etc., and in particular, a vehicular lamp having a good light emission range around the periphery of the lens. It is about.

[0002]

[Prior Art]

 A conventional vehicle lamp of this type will be described with reference to FIGS. 3 and 4. In this example, a rear combination lamp including a stop lamp, a turn signal lamp and a back lamp will be described. In the figure, 1 is a housing. This housing 1 is provided with an opening 10 on the front surface, and an adhesive recess 11 is provided on the entire peripheral edge or a part of the front opening 10. In addition, a separate reflector (not shown) is provided inside the housing 1, or a reflection surface is directly provided on the inner surface of a portion of the inner surface corresponding to the reflection portion. In the figure, 2 is an inner lens. The inner lens 2 has a shape capable of covering the front opening 10 of the housing 1, and the leg 20 is integrally provided on the entire peripheral edge or a part thereof, and an appropriate prism 21 is engraved on the inner surface. In the figure, 3 is an outer lens. The outer lens 3 is integrally provided with an adhesive leg portion 30 on the entire peripheral edge or a part thereof, and an appropriate prism 31 is engraved on the inner surface. The inner lens 2 is fixedly arranged in the front opening 10 of the housing 1 by appropriate means. Next, the adhesive leg portion 30 of the outer lens 3 is fixed to the attachment concave portion 11 of the housing 1 by adhesive sealing with the hot melt 4. As a result, the housing 1, the inner lens 2 and the outer lens 3 form a lamp chamber 40. A light source bulb (not shown) is arranged in the lamp chamber 40. In such a vehicular lamp, when the light source bulb is turned on, the light from the light source bulb is radiated forward (backward with respect to the vehicle) in a predetermined light distribution pattern through the inner lens 2 and the song lens 3. ..

[Problems to be solved by the device]

 However, in the above-described conventional vehicular lamp, the standing wall portion of the adhesive recess 11 of the housing 1 can be seen between the peripheral edge of the inner lens 2 and the peripheral edge of the outer lens 3. For this reason, for example, when the housing 1 is made of black synthetic resin or the like, when the vehicle lamp is viewed from the front, the black housing 1 is transparent between the peripheral edge of the inner lens 2 and the peripheral edge of the outer lens 3. As a result, a dark part (blackening) D (lattice hatching in FIG. 3 and a thick line in FIG. 4) is generated on the outer circumference of the lamp, and the light emission range around the edges of the lenses 2 and 3 looks poor. There's a problem. In the figure, I.D. P indicates the position of the eyes.

An object of the present invention is to provide a vehicular lamp having a good appearance of the light emission range around the periphery of the lens.

[0005]

[Means for Solving the Problems]

 The present invention is characterized in that at least one of the inner lens and the outer lens is provided with a blind portion for blocking the view of the housing from between the peripheral edge of the inner lens and the peripheral edge of the outer lens. ..

[0006]

[Action]

 According to the present invention, when the vehicular lamp is viewed from the front by the above structure, the blind part blocks the housing from being seen between the peripheral edge of the inner lens and the peripheral edge of the outer lens. The appearance of the light emission range at the periphery of the lens is improved.

[0007]

【Example】

 An embodiment of the vehicular lamp of the present invention will be described below with reference to FIGS. 1 and 2. This example describes a rear combination lamp. In the figure, the same reference numerals as those in FIGS. 3 and 4 indicate the same elements. In the figure, reference numeral 5 denotes a blind portion integrally protruding from the inner lens 2. The blind portion 5 is integrally provided so as to project from the outside of the corner of the inner lens 2 toward the inside of the corner of the outer lens 3, and the peripheral edge of the inner lens 2 (outside the corner) and the outer lens 3 are covered. The wall of the adhesive recess 11 of the housing 1 is blinded so that it cannot be seen from the periphery (inside the corner). At least one of the outer surface (the surface facing the outer lens 3) and the inner surface of the blind portion 5 is provided with a knurl or prism 50 for light reflection or light diffusion.

Since the vehicular lamp of the present invention in this embodiment has the above-described structure, when the vehicular lamp is viewed from the front, the blindfold portion 5 is located between the peripheral edge of the inner lens 2 and the peripheral edge of the outer lens 3. Since it blocks the view of the housing 1 from the outside, the dark part on the outer periphery of the lamp disappears, and the appearance of the light emission range around the edges of the lenses 2 and 3 is improved. In particular, in this embodiment, since the knurls, prisms, etc. 50 are provided in the blindfold portion 5, light is reflected or diffused, and the blindfold effect of the housing 1 of the blindfold portion 5 is further enhanced.

Although the rear combination lamp has been described in the above embodiment, the vehicle lamp of the present invention can be used for a vehicle lamp having a double lens structure other than the above-mentioned rear combination lamp. ..

Further, in the above-mentioned embodiment, the blind portion 5 is provided on the inner lens 2, but the blind portion 5 is provided on the outer lens 3 in addition to the inner lens 2 or on both the inner lens 2 and the outer lens 3. It may be provided.

[0011]

[Effect of the device]

 As is apparent from the above, the vehicular lamp of the present invention blocks at least one of the inner lens and the outer lens from seeing the housing from between the peripheral edge of the inner lens and the peripheral edge of the outer lens. Since the blindfold is provided, when the vehicle lamp is viewed from the front, the blindfold blocks the housing from being seen between the peripheral edge of the inner lens and the peripheral edge of the outer lens, so the dark area around the lamp disappears. , The appearance of the light emission range at the periphery of the lens is improved.
