JPS59132385A - Internal illumination type clock - Google Patents

Abstract

PURPOSE:To achieve a function as a clock even if the position corresponding to a cap part is not illuminated, by arranging the cap part of a ring shaped lamp provided to the rear part of a light pervious dial in a range from 2 o'clock to 6 o'clock. CONSTITUTION:The cap part 14 of a ring shaped fluorescent lamp provided to the rear part of the light pervious dial 7 of an internal illumination type clock 1 provided in a park is arranged so as to correspond to the range from 2 o'clock to 6 o'clock on the time display of the dial 7. Even if the position corresponding to the cap part 14 is not illuminated by the lamp 12, there is day light or a clock user is not almost present at the time corresponding thereto and therefore, a function as a clock is achieved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an internally illuminated timepiece whose dial is illuminated from behind by an annular lamp.

[Technical background of the invention]

Conventionally, in this type of timepiece, the position of the base of the house-shaped lamp is arranged depending on the position of the socket, etc., and is therefore different for each timepiece.

[Problems with background technology]

However, since the base of the annular lamp does not emit light, it becomes dark at the position corresponding to the base of the dial, and the time display and hands become invisible, making it impossible for the watch to function as a timepiece. The drawback is that it cannot be done.

This drawback is particularly noticeable in the case of clocks that are installed in parks and the like and are powered by solar cells. This is because, due to power consumption, the annular lamp is not fully lit and is dimmed to provide the minimum brightness necessary, so even with diffused light, the half-plate at the base is not illuminated. be.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide an internally illuminated timepiece that can fully function as a timepiece even if the position corresponding to the base is not illuminated by an annular lamp.

[Summary of the invention]

In the internally illuminated timepiece of the present invention, even if the time display and hands become difficult to see, in order to minimize the effect on the role of notifying the time, the cap of the annular lamp is placed between the two sides of the time display on the dial. This is because there is daylight or there are hardly any people using the watch during the time period when the base is located.

[Embodiments of the invention]

Next, one embodiment of the present invention will be described based on the drawings.

(1) is an internally illuminated clock installed, for example, in a park, which is supported by a column (2) and driven by a solar cell (3) also supported by the column (2). Note that the base of this support (2) stores power from a solar cell (3) via an electric wire (4) placed inside the support (2), and also controls the dimming of a template lamp (5) to be described later. Control unit (6
) is provided.

The watch (1) is formed into a rectangular box shape, and has a translucent milky white dial (7) with a time display on the outer periphery on the front, both long and short hands (8) (9), and a drive unit aα. It has a time display part αυ with a time display part αυ, and is provided with an annular base lamp α2 for illumination and a ballast (13) for lighting this lamp (12). And this lamp α2
The clasp part α is set to correspond to the range from 2 o'clock to 6 o'clock on the dial (time display).

The gff surface of the time display section αυ is covered with a transparent plate α9, and the entire time display section αυ is formed to be openable and closable using a hinge (16). Further, (17) is a support frame that supports the lamp (12).

Next, the operation of this embodiment will be explained.

When lamp α2 is turned on, the illumination becomes dark at the position corresponding to the base (14) where this lamp < 121, making it difficult to see the time display and hands (81 (9) on the dial (7). Between 2:00 and 6:00, there are almost no users of clocks set up outdoors, such as those in parks.
Therefore, since there is daylight between 2:00 pm and 6:00 pm, internal lighting is not necessary.

Based on this idea and considering the size of the cap part αa, in the case of a 40 WIR type fluorescent lamp (FCL40), the straight shape is 680 mm, and the cap part is approximately 60 mm out of one rotation.
The optimum time at which the mouthpiece α-shape should be placed is from 2 o'clock to 4 o'clock in order to tighten the temperature.

This is because morning is the time when there are the least number of people outdoors, and afternoon is the time when there is daylight regardless of the season.

Note that the power source for lighting the internally illuminated timepiece is not limited to a solar cell, but a normal commercial power source, battery, etc. may also be used.

Furthermore, even in the case of a 24-hour watch, it is naturally possible to place the base between 2 o'clock and 6 o'clock when the time is displayed on the dial.

This is because in the morning, before 2 o'clock, there are still people passing by, and in the afternoon, after 6 o'clock it is dark.

〔Effect of the invention〕

According to the present invention, since the base of the annular lamp is placed within the range from 2 o'clock to 6 o'clock of the time display on the dial, there are almost no users of the watch in the morning, making it difficult to see the time display and hands. In addition, in the afternoon, the time display and hands will not be difficult to see due to daylight, and the watch can fully fulfill its role as a watch.
