[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bell lighting structure used as a decoration for a mechanical timepiece.

[0002]

2. Description of the Related Art Conventionally, there is a mechanical timepiece in which an LED (light emitting body) flashes in time with a song. But there was no mechanical clock with a flashing bell. Of course, if the bell used for the mechanism clock can be made to blink, the commercial value of the mechanism clock will increase accordingly.

[0003]

[Problem to be Solved by the Invention] Therefore, it is conceivable to arrange a luminous body inside the bell. However, simply arranging the luminous body inside the bell only causes the tip of the luminous body to shine in a dot shape. The entire bell does not glow. Also, if the lamp is mounted inside the bell, the whole bell will glow, but the power consumption is large, and there is a problem that the life of the lamp is shortened when blinking.

It is an object of the present invention to provide a bell lighting structure for use in a mechanical timepiece which solves the above problems.

[0005]

That is, the bell lighting structure used in the timepiece of the present invention is divided into two parts, a front part and a rear part, and the front part is made of a transparent material. Construct and apply a pearl coating to the surface, on the other hand, form a convex mirror part and a concave mirror part close to the inner surface of the rear component,
A luminous body is disposed adjacent to the convex mirror.

Here, the pearl coating is a coating in which a certain pigment is mixed with a transparent coating, and the characteristic of the coating is that the light impinging on the pigment undergoes complex multiple reflections to produce a pearl luster. The point is to exhibit. And the pigment used here is preferably a high refractive index, a transparent particle, a particle size of about 5 to 200 μm, a thin plate or scale, in a paint or a synthetic resin. It is a substance having conditions such as being well dispersed and arranged in the inside, and for example, titanium dioxide or the like is used.

[0007]

As described above, since the luminous body is used, the power consumption is small and the life is short. And the current O
The luminous body blinks by the N-OFF operation, and the luminous body shines like a dot. This point light reaches the adjacent convex mirror portion and is diffused here. That is, the point light beam is spread. A part of the diffused light thus obtained reaches the front component, and the diffused light that does not directly reach the front component is collected by the concave mirror and reaches the front component, Here, since the front component is coated with pearl, the light that reaches the part travels in various directions in the front component, and as a result, the entire front component of the bell is blurred. Glow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a bell made of a transparent resin material. The bell 1 has a front component 1a and a rear component 1 which are divided into two sections.
and b are collated and integrated.

A pearl coating is applied to the surface a of the front component 1a. A convex mirror 2 and a concave mirror 3 are formed close to each other on the inner surface of the rear component 1b. Specifically, a convex mirror portion 2 is formed on the inner surface of the central portion of the rear component 1b by vapor deposition, and a concave mirror portion 3 is formed on the inner surface of the upper portion of the rear component 1b by vapor deposition continuously from the convex mirror portion. I have.

Reference numeral 4 denotes a luminous body provided in the bell 1 to illuminate the bell 1, and 5 denotes a wiring. The luminous body 4 is disposed so as to be close to the convex mirror section 2 (so that the distance between the tip of the luminous body 4 and the convex mirror section 2 is within 3 mm). In other words, if they are arranged at a distance of 3 mm or more, the emitted light does not spread over the entire bell 1, so that the desired brightness of the entire bell 1 cannot be obtained. Therefore, the light-emitting body 4 is
Or it is preferable to arrange them so that the distance from the convex mirror portion 2 is within 3 mm.

The lighting structure of the bell 1 having the above structure is used, for example, as follows. Simultaneously with the sound of the music box, the light-emitting body 4 is intermittently energized, and the light-emitting body 4 glows like a dot. This point-like light reaches the adjacent convex mirror portion 2,
It is spread here. That is, the point light beam is spread.
A part of the diffused light thus obtained reaches the front component 1a, and the diffused light that does not directly reach the front component 1a is collected by the concave mirror unit 3 and the front component 1a is collected. Since the pearl coating is applied to the surface a of the front component 1a, the light reaching the portion travels in various directions in the front component 1a, and as a result, the bell 1 The whole glows softly and softly.

[0012]

[Effects of the Invention] As described above, according to the present invention,
Since the luminous body (LED) is used, the power consumption is small, and the luminous body itself emits a point-like light. However, the light is diffused by the convex mirror and the like, and the bell can be radiated softly. Since the light-emitting source is a light-emitting body (LED), the life is not shortened even when used for lighting.
