Abstract

PROBLEM TO BE SOLVED: To change the brightness of a light source according to the lapse of time for producing impression of a candle by arranging at least two bulbs vertically, flashing only the upper bulb, covering the outside of the bulbs with an opaque inner cover, and further covering the outer surface thereof with a cylindrical lens member. SOLUTION: A candle-shaped light source 10 for lantern is formed of a main body 11 and a light-emitting part 12 provided thereon, and the light- emitting part 12 is the bulb of a light-emitting element 12a arranged on the upper side, the bulb of a light-emitting element 12b arranged on the lower side, and a translucent cover 12c for covering their outer surfaces. When the bulbs are lighted, the light of the vertically arranged light-emitting elements 12a, 12b is reflected by the translucent cover 12c to emit a slender light like the flame of a candle. Furthermore, the light is expanded by a lens member arranged on the circumference and diffused over the whole inner surface of the lantern. Only the upper light-emitting element 12a of the two light-emitting elements is flashed at prescribed intervals to produce the impression of the upper part of the flame being flickered by wind.

2. Description of the Related Art In general, a candle is used as a light source for lighting a lantern. However, the candle must be replaced each time it is burned out, and the handling is troublesome and there is a fear of fire. Therefore, an incandescent light bulb was put in a lantern and replaced with a candle. However, the light was turned on and off in order to make the sensation more like a candle flame. Furthermore, in recent years, with the progress of ICs and other electronic control technologies, not only the light bulbs are simply flickered, but also two light bulbs are arranged one above the other to give a sense of flame, and only the upper light bulb is kept for a predetermined time. Blinking is also performed at intervals. On the other hand, an incandescent light bulb used as a light source for flickering a lantern becomes hot due to long-time use, and there is a danger of fire.

However, flickering at a predetermined interval has not been sufficient as a means for giving a sense of flame. In addition, when a light emitting element is used as a light source, the light source itself is small even if its luminous intensity is sufficient,
When trying to illuminate a large lantern, there is a partial difference in brightness between the lantern and it has been difficult to achieve sufficient brightness.

An object of the present invention is to dispose at least two light bulbs vertically in the vertical direction so that only the upper light bulb blinks, and the outside of the light bulbs is covered by an inner cover made of an opaque material. The problem is solved by covering the outer surface with a cylindrical lens member. Also, 2
Among the individual light bulbs, there is provided a control means for alternately turning on and off the upper light bulb and blinking the lighting period at shorter intervals.

When the light bulb is turned on, the light of the light bulbs arranged above and below hits the cover and is diffusely reflected, and emits a thin and long light like a candle flame. Further, the light is expanded by the lens member arranged on the outer periphery, and diverges the light on the entire inner surface of the lantern. Of the light vertically formed by the two bulbs, only the upper part flickers at a predetermined interval, and the upper part of the flame feels swaying in the wind. In addition, it blinks at shorter intervals during the lighting period.

According to the first aspect of the present invention, in the flame-shaped cover, the light emitting element illuminating the upper part flickers and the light emitting element illuminating the lower part is always lit, so that the light emitting element illuminating the upper part flickers. As the brightness above the lantern changes,
It gives an impression similar to the fluctuation of a candle flame. Further, irradiating a lantern having a wide light-emitting surface with the same brightness as a whole can be achieved even though light from a light-emitting element having a small light-emitting area is used by a lens member covering the outer surface. In addition, since the light of the light emitting element is used, the heat generation is small and there is no danger of fire, the vibration resistance is excellent, and the life is long. According to the second aspect of the present invention, the upper light bulb is repeatedly turned on and off in a relatively short period of time, so that the upper part of the flame has the appearance of being shaken by the wind. And so on.
