Description

The present invention relates to a light diffusion method in an illumination device and a structure of an acoustic device. However, utilization of this invention is not restricted to the illuminating device and sound apparatus which were mentioned above.

In recent years, many bulb-type lighting devices using LEDs (light-emitting diodes) as light sources have been commercialized from the viewpoint of energy saving. The important design issue is how to efficiently dissipate the heat generated in the light emission process of the LED and further spread the light diffusion effect throughout the bulb.

The spread of portable devices such as smartphones is tremendous, and many acoustic devices that are equipped with a nearby wireless transmission device and receive music playback signals transmitted from now on are cordless. These acoustic devices simply have a wireless reception function, and the form and usage thereof do not change.

Moreover, there is an illuminating device that is configured to include a sound output means and a means for detecting and controlling ON / OFF input of the light emitting means in the illuminating device that is attached to the power line and connected by power line communication (for example, Patent Document 1).

Further, there is an illuminated audio reproduction device characterized in that a base that can be attached to the illumination power supply socket is provided as a power supply unit, and the audio input means is provided with a wireless communication signal processing means (see, for example, Patent Document 2).

Japanese Patent No. 4724504 JP 2008-193189 A

However, in the lighting device connected to the power line communication described in Patent Document 1, a device for transmitting a music signal is limited, and an intermediate device for placing the signal on the power line is required. Not good. Moreover, it is hard to say that power line communication itself is widespread.

In addition, in the sound reproduction apparatus with illumination described in Patent Document 2, a function as an illumination device that illuminates the lights evenly with a configuration in which the light source is handled only downward, and a problem that lacks the texture of the lights are given as an example. .

In order to solve the above problems, the present invention provides a means for diffusing light from a light emitting module to the entire bulb cover with an edge light of the bulb cover, an acoustic device having a wireless reception function and a speaker not based on power line communication. Arrange and provide both light and sound functions.

An embodiment of the present invention provides an illuminating acoustic device including a plurality of light emitting modules, a light bulb cover having an edge light effect, a speaker, and a wireless function. Hereinafter, examples of the present invention are referred to as illumination sound devices.

According to this structure, the light from the light emitting module introduced into the inner side from the end face of the bulb cover repeats total reflection on the thick inner surface by the blast treatment applied to the inner side of the bulb cover, and proceeds to the upper part. The entire light bulb cover is uniformly brightened by this reflection effect.

According to the illuminating acoustic device of the present invention, a thick light bulb cover is excellent in acoustic characteristics as a speaker box and has a wireless reception function, thereby facilitating input of music signals.

As described above, according to the present invention, the acoustic device can be used wirelessly without worrying about the power source, and is suitable not only for direct illumination, but also for use in lighting fixtures where the brightness of a stand or the like needs to diffuse evenly. It is.

The light bulb cover 12 is preferably made of a transparent resin material having a high refractive index, such as acrylic or polycarbonate.

Next, an example of an audio device in the present embodiment will be described with reference to FIG.

Referring to FIG. 3, a circuit is configured by a circuit board 15 on which a nearby radio receiving circuit is arranged, a power supply board 18, and a light emitting diode module 14, and a speaker 13 is fixed to a cover 16 covering the circuit board 15. Yes.

Here, near-field wireless is communication performed using radio waves, infrared rays, ultrasonic waves, or the like. Various standards such as wireless LAN, IrDA, and Bluetooth (registered trademark) are available as standards enabling wireless communication. In this embodiment, these known wireless communication techniques can be used.

Further, the near field radio reception circuit may be a communication module that performs communication with another unit of the present embodiment and controls reproduction by multi-channel.

Following the above description, the heat dissipating element 11 for eliminating the heat of the light emitting diode module 14 is disposed on the back surface of the circuit board 15. The heat radiating element 11 efficiently dissipates heat to the outside air.

Following the above description, the cover 16 prevents heat generated from the light emitting diode module 14 and protects the electronic components of the board 17 on which the nearby wireless receiver circuit is arranged from the heat.

Following the above description, the outside of the cover 16 reflects light leaking from the end face of the bulb cover 12 from the light emitting diode module 14 and diffuses the light into the space inside the bulb cover 12.
