Description

[Detailed explanation of the idea] The present invention relates to a light with a lantern.

Generally, a light with a lantern has a lantern window in a part of the peripheral wall of its main body case, and is used for position indication, signaling, etc. even when it is turned off in rainy or stormy weather.

Conventional lights with lanterns have a structure in which a cover is detachably attached to the opening of the lantern window using screws, etc., and the opening and the periphery of the cover are connected along a complicated curved surface. A special sealing member was inserted between them to maintain watertightness.

However, with such conventional devices, if the seal portion is damaged or the sealing function deteriorates due to long-term use, it is not possible to prevent rainwater from entering during rainy weather.

If rainwater etc. seeps into the inside of the main body case, not only will the cover become cloudy, making it impossible to obtain the desired luminous intensity, but in severe cases, it may cause poor electrical insulation or poor welding. , which will significantly shorten its lifespan.

In addition, since it is necessary to specially provide the above-mentioned sealing part in the main body case, the number of assembly steps increases and the cost becomes high.Moreover, because the main body case has the above-mentioned opening, it is extremely vulnerable to shocks caused by dropping, etc. It had the disadvantage of being a structure.

The present invention has been made in view of the above-mentioned conventional drawbacks, and aims to provide a device that reliably prevents water from seeping into the main body case from the lantern window and is also excellent in strength.

A feature of the present invention is that in a light with a lantern that has a lantern window in a part of the peripheral wall of the main body case that houses the light source, the outer edge of the cover that covers the opening of the lantern window is removed from the main body case. It forms a bottomed cylindrical body that is fused and integrated with the opening edge and is open only at one end in the longitudinal direction, and furthermore, the inner surface of the peripheral wall of the main case has a protrusion near the opposite side in the longitudinal direction of the opening edge. are provided protrudingly, guide grooves are formed facing each other, and the opposite sides in the longitudinal direction of the support plate to which the light source for the lantern is attached are fitted into the guide grooves, with the opposite sides in the longitudinal direction of the support plate having the light source for the lantern attached thereto, and the support plate is fitted into the bottomed guide groove. The interior of the bottomed cylindrical body is divided into a power source storage chamber and a light source storage chamber, and a cap is provided with another light source.
