Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a humidity sensor* suitable for digitally displaying humidity outdoors.

There are various types of humidity display devices that digitally display humidity outdoors, including those that use high-intensity lamps;
Some types of %H rotate a movable plate with numbers on it, and others have %H that rotates the numbers.

However, these lamps have problems such as short lamp life, high power consumption, and movable parts that are prone to failure.

Also, if maintenance is not done adequately, the dots that make up the numbers will become dull. The present invention is intended to improve the problems of the conventional humidity display device, and will be explained below with reference to the drawings.

Figure 1 shows the basic concept of this invention.
i dots forming numbers (210 partial rows opaque sheet glass, t formed using plastic IIk
Shock plate (35 is an optical fiber made up of one or more optical fibers, one end of which is located at each dot, so that the light passing through the optical fiber causes the corresponding dot to shine).

-J+ of the above optical fiber! 1 is fixed to the dot part of the front plate (11), and the other end is the light generating device (located 41K).

That is, the light generating device (4) is composed of a light source (for example, a halogen lamp) (5) and a reflector (RIFLIiOTOR) (61) that reflects the light emitted from the light source (!S). The other end of the optical fiber (61) is located at the focal point of the reflector (61).

Therefore, when the light source (δ) is turned on by the power from the power source (7), the light enters from the other end of the optical fiber (31) and reaches one end.

Fig. 2 #i This shows a humidity display device constructed based on the concept as shown in Fig. 1, in which dot groups A and B forming a two-digit number and a dot group displaying r%J are shown. O
This shows the case where the surface of the display device TDe) is formed.

Therefore, for example, 34 dots are displayed by the three dot groups B and O.

In addition, in Figure 2, the black circle is selected and the number "3"
It shows "4" and "ls". On the other hand, white circles are unselected dots.

FIG. 3 shows an embodiment of this invention.
11 is the front plate, (3-1) to (A-n) are optical fibers, (4: is the first equipment ffi, (51 is the light source, (6) is the reflector, (71a power supply * (''') ~ (8-n)
A control circuit (9) which is a TJ optical switch and is installed in the middle of each optical fiber and selects 9 individual dots.
There will be a selection system. Trout is a humidity senna.

This humidity sensor 60 is placed outdoors at a predetermined location IlK.

The humidity in the air is measured, and the circuit (9) selectively controls the optical switch based on the humidity measurement signal generated from such a humidity sensor.

That is, the display is performed in the same manner as a conventional digital humidity display device.

In the embodiment, an optical switch is provided for each line of one optical fiber, but it is also possible to provide one optical switch for a plurality of lines.

By the way, like this invention with optical fiber.

A humidity display device that combines a light source and one reflector consumes less power than the conventionally used one in which wraps are arranged in a dot shape, and since there is only one light source, it is easy to maintain. The cost required for this is also low.
