Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is characterized in that the front opening, which is formed by going around from the front side of the body to the side side, is integrated with the front side lens and the side side lens of a predetermined area. This invention relates to a vehicular lamp having a lamp chamber sealed with an outer lens formed in a circular shape, and in particular, an inner lens is installed in the lamp chamber to efficiently condense light emitted from a light source to a side lens. The present invention relates to a vehicular lamp having the above-mentioned structure.

[Conventional technology]

Conventionally, an opening formed by going around from the front side to the side side of the body 50 is sealed with an outer lens 51 in which a front side lens 51a and a side side lens 51b are integrally or integrally formed to form a light chamber 52,
When illuminating the front lens 51a, the side lens 51
A vehicular lamp is known that is configured to simultaneously illuminate both sides of the vehicle. For example, as shown in FIG. , that is, the marker lenses are configured to be illuminated at the same time. However, when the distance between the light source 53 and the side lens 51b is large, the side lens 51b having a predetermined area from the light source 53
Since the solid angle W of the irradiated light incident on b is small and the amount of luminous flux is also small, sufficient illuminance cannot be obtained and the lamp cannot function satisfactorily. Therefore, as shown in FIG. 5A, an auxiliary light source 54 dedicated to the side lens 51b is arranged inside the side lens 51b, separate from the main light source 53, and this is linked to the main light source 53. Proposed.

[The problem that the idea attempts to solve]

However, according to the above configuration, the side lens 51
A dedicated space 55 must be formed to accommodate the auxiliary light source 54 dedicated to b, and the body 50
In addition to increasing restrictions on the design of the auxiliary light source 54, wiring and other manufacturing steps for the dedicated auxiliary light source 54 also increase, which not only increases the time and effort required for assembly, but also increases the risk of wire breakage and other electrical accidents during use. This has led to problems such as the occurrence of problems and an increase in the number of maintenance and inspection items, making it complicated.

The present invention was devised in view of the above-mentioned problems, and it provides a sufficient amount of luminous flux to the side lenses without requiring a dedicated light source for the side lenses or creating constraints on the shape of the body. It is an object of the present invention to provide a vehicular lamp equipped with an inner lens which can be obtained and which does not cause a dark area in the lamp chamber when viewed from the front.

[Means to solve the problem]

In order to achieve the above object, a vehicle lamp equipped with an inner lens according to the present invention has an opening formed by wrapping around from the front side of the body to the side side. In a lamp chamber that is sealed with an outer lens that is integrally or integrally formed, an outer lens that allows partial transmission of irradiated light to an inner lens that is disposed between the light source and the side lens. In addition to forming a region, the inner lens is fixed in the lamp chamber in a state in which it is floated slightly higher to the front side of the outer lens.

[Effect]

According to the above configuration, when the light source is turned on, the irradiated light directed toward the side of the body is condensed by the inner lens, and the side lens is illuminated with a sufficient amount of luminous flux.

Furthermore, the irradiated light that has passed through the outside area of the inner lens is reflected toward the front side of the lamp chamber by a reflective surface formed on the inner surface of the body.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle lamp equipped with an inner lens according to the present invention will be described below with reference to the drawings.

1 to 3 show a first embodiment of a vehicular lamp equipped with an inner lens according to the present invention, and 1 is a body of the vehicular lamp. This body 1 has an opening formed by going around from the front side to the side side thereof, and is sealed with an outer lens 2 in which a front side lens 2a and a side side lens 2b having a predetermined area are integrally or integrally formed. A lamp chamber 3 is formed, and a reflective surface 1a is formed on the inner surface.
A light source 6 attached to a socket 5 is inserted through the rear opening 4 of the body 1 and supported on the edge of the opening 4.
When the light source 6 is turned on, the irradiated light and reflected light are emitted from the front lens 2a or the side lens 2b of the outer lens 2 to the outside of the lamp chamber 3. 7 is an inner lens interposed between the light source 6 and the side lens 2b having the above configuration;
The light beam emitted from the light source 6 to the side is focused by this inner lens 7 onto the side lens 2b,
It is designed to increase the amount of luminous flux.

In this embodiment, the inner lens 7 is
The reflective surface 1a formed on the inner surface of the body 1 is provided with a diagonal notch 7a that allows partial transmission of the irradiated light, and is raised slightly higher from the reflective surface 1a toward the front side of the outer lens 7. , is fitted and fixed to an insertion rib 8 formed on the inner wall 1b of the body 1, and among the light irradiated from the light source 6 to the side of the body 1, the irradiated light A that passes through the inner lens 7 is ,
The light is focused by the inner lens 7 and sent to the side lens 2.
irradiate the diagonal notch 7a of the inner lens 7.
Irradiation light B transmitted onto the reflective surface 1a of the body 1 from the outside area of the lens, such as the lens and its lower side, is reflected toward the front side of the lamp chamber 3 on the reflective surface 1a. This prevents the appearance of dark areas when the outer lens 2 is viewed from the front, which would otherwise occur due to the inner lens 7 being installed in the lamp chamber 3.

FIG. 4 shows a second embodiment of a vehicle lamp equipped with an inner lens according to the present invention, in which the inner lens 17 itself has an irradiation light transmitting portion or a transmitting region 17a which is an area outside the lens, and a predetermined area. Prism portions or prism portion regions 17b having a light converging effect in the direction are provided alternately or in a staggered manner, and the irradiated light B incident from the light source 16 to the transmission portion or transmission region 17a, that is, the area outside the lens, is Irradiation light A that is directly reflected toward the front side of the lamp chamber 13 on the reflective surface 11a of the body 11 and incident on the prism portion or prism portion region 17b is reflected by the prism portion or prism portion region 17b to the side lens 1.
The light will be focused on 2b. Therefore, when the outer lens 12 is viewed from the front, the inner lens 17
It is possible to prevent the occurrence of dark areas due to

Structure of inner lenses 7, 17 and light chambers 3, 13
It goes without saying that the fixing structures therein are not limited to the illustrated embodiments, and can be modified as appropriate within the scope of the purpose of the present invention.

[Effect of idea]

Since the vehicle lamp equipped with the inner lens according to the present invention is configured as described above, even in a vehicle lamp in which the side lens is located relatively far from the light source, it is possible to use the side lens exclusively for the side lens. It is possible to irradiate the side lens with a necessary and sufficient amount of luminous flux without requiring an auxiliary light source, thereby reducing costs by omitting wiring and other configurations, and reducing power consumption. In addition, it not only expands the degree of freedom in shaping and reduces the number of work hours, but also prevents the occurrence of dark areas in the lamp chamber and enables uniform light distribution, which will improve the practicality of the invention after implementation. It has excellent effects.
