Description

[Detailed description of the invention] (Field of industrial application) The present invention mainly relates to a desk lamp as an indoor lighting device, and in particular provides a novel lighting device that combines a short wave and indoor antenna for television with a desk lamp. It is something to do.

(Prior art) In the past, indoor antennas for short-wave radios, televisions, etc. and desk lamps were used as separate devices, but the installation of the indoor antenna as a separate device itself gave a decorative image to the room. In addition, it was clumsy to operate in order to select the directivity of the radio waves, and the selection of the installation location was not determined, giving the impression that it was an accessory that was a nuisance.

Furthermore, desk lamps also have the disadvantage that simply installing them near an indoor television or the like does not balance the decorative image with the separately installed indoor antenna.

(Technical Issues) The present invention was developed in view of the shortcomings of the prior art, and it solves the problem of the poor decorative image, imbalance, and instability of installation conditions between a desk lamp and an indoor antenna, respectively. The technical challenge is to do so.

(Technical means) In order to solve the above technical problem, the present invention combines a shortwave (FM) radio, television, and other indoor antennas with a desk lamp.
Specifically, as shown in the embodiment shown in the drawings (FIGS. 1 to 3), the configuration is as follows.

Reference numeral 1 denotes a desk lamp body which is a household electrical appliance, and in this embodiment, a cylindrical type with an umbrella cover 2 is mainly used.

3 is a stand base, and electrical parts are housed inside.

Reference numeral 4 denotes a column protruding from the stand base 3. A light bulb 5 is attached to the tip of the column 4, and a light bulb socket 4A for energizing is attached.

Reference numeral 6 denotes a frame body of the umbrella cover 2, and by rotatably attaching the frame portion 7 of the frame body 6 to the light bulb 5 to the light bulb 5, the umbrella cover 2 can be attached to the desk lamp body 1.
be fixed to.

Therefore, the umbrella cover 2 functioning as a light shielding part is rotatable around the light bulb 5.

Reference numeral 8 denotes a pair of indoor antennas, and the pair of antennas 8 are fixed in a dipole shape to a part of the annular frame 6 on the upper surface side of the umbrella cover 2 by an appropriate elevation rotation mechanism 6A with the antennas 8 directed toward the outer circumference. It is mandatory.

For example, 6D is a nut, 6C is a screw body, and 8C is a mounting hole for the indoor antenna 8. By screwing the mounting hole 8C of the antenna 8 into the mounting piece 6B protruding from the frame 6, antenna 8
Since the indoor antenna 8 is configured to rotate in elevation, there is no need to take the trouble of expanding and contracting the indoor antenna 8 to select the directivity of radio waves. In this way, if the size of the antenna from both ends is large compared to the wavelength of the radio wave, it will become a highly directional antenna, and its decorative image will also be improved.Furthermore, by using the light bulb 5, it can be used as a fluorescent lamp like the conventional technology. Noise is less likely to enter than in the case of

Reference numeral 9 denotes electrical wiring for leading from the terminal of the indoor antenna 8 to the stand base 3.

10 is a power cord.

(effect) The above technical means works as follows.

An umbrella cover 2 formed by attaching a part of a pair of dipole-type indoor antennas 8 is attached to a light bulb 5 via a mounting frame 7 that is rotatably attached to the light bulb 5 in the direction of arrows A to B with the support 4 as the central axis of rotation. At the same time, the elevation angle rotation mechanism 6A of the indoor antenna 8 rotates the indoor antenna 8 in the direction of arrows C to D to give an appropriate opening angle θ to the pair of indoor antennas 8. You can choose the directionality of the radio waves.

That is, when the horizontal spacing between both ends of the dipole indoor antenna 8 becomes approximately the wavelength of the signal frequency due to the elevation rotation mechanism 6A, this becomes a blunt resistance due to reactance characteristics, resulting in an antenna with high gain.

Furthermore, by installing an amplifier specifically for supplying power inside the stand base 3, the sensitivity of the antenna can be enhanced.

Incidentally, a pair of dipole-type indoor antennas 8 may be fixed to the frame 6 of the umbrella cover 2 in the horizontal direction from the beginning, thereby enhancing the decorative image of the indoor antenna 8. .

Therefore, the present invention has the following unique effects.

(a) Since the mounting frame 7 of the frame 6 of the umbrella cover 2 having the pair of indoor antennas 8 is rotatably mounted on the light bulb 5, the umbrella cover 2 can be simply rotated in parallel. A pair of indoor antennas 8
It is possible to easily match the direction of radio waves while maintaining the suppression angle, and it is extremely practical because there is no need to twist each antenna individually around the base end as in the conventional technology. .

(b) Above the light bulb 5, a pair of dipole-type indoor antennas 8 are fixed to the umbrella cover 2 by an elevation rotation mechanism 6A so that they can be raised and lowered, so that they can easily receive reflected and refracted radio waves. In addition to being easy to use, it is also practical because there is no risk of noise such as rattling compared to conventional fluorescent lamps.
