Next, please refer to FIGS. 2A and 2B together with FIG. 3A.
3A and 3B are operation schematic diagrams when the color of the object is detected by operating the variable color light emitting module shown in FIG. 2A.
The overall operational relationship of the variable color light emitting module 1 of the present invention will be described in more detail.
When the user wants the variable color light emitting module 1 to emit light of the same color as that of the object lamp, that is, the table lamp TL that emits blue light, the switch 16 first switches the variable color light emitting module 1 to the operating state.
Subsequently, the variable color light emitting module 1 is brought close to the table lamp TL, and the color detecting means 13 is directed to the light source.
After that, for example, the external force F is applied to the elastic portion 11 of the variable color light emitting module 1 by crushing, grasping, and / or pressing, and the elastic portion 11 is deformed. Arise.
At the same time, the pressure sensor 12 outputs a color change signal S1 to the color detection means 13 based on a change in the internal pressure of the elastic portion 11.
After the color detection means 13 receives the color change signal S1, detection is started to detect the wavelength of light emitted from the table lamp TL (representing the color of light emitted from the table lamp TL), and to this wavelength. A corresponding color signal S2 is generated.
The processing means 17 sends a control signal S3 based on the color signal S2, and controls the light emitting means 14 to emit light corresponding to the color signal S2.
In this embodiment, since the wavelength of the light incident on the color detection means 13 and the light emitted from the variable color light emitting module 1 are substantially the same, the variable color light emitting module 1 has the same color as the object. Sensation that can be emitted can be brought about.

  It should be particularly explained that the above-mentioned "wavelengths are substantially the same" means that light within a certain range is considered to be the same color due to limitations of the physiological structure of the human eye. It means that they are the same color sensuously, however, on the numerical value measured with the measuring instrument, both the incident and the outgoing are said to be “wavelengths are almost the same”. It can be a thing.

Next, please refer to FIGS. 2A and 2B together with FIG. 3B.
In the present embodiment, a case where the object is red paper N is taken as an example.
Compared to the embodiment described above, the table lamp TL is a light source that actively emits light, whereas the paper N of this embodiment is not a light source.

When the user wants the variable color light emitting module 1 to emit light having substantially the same color as that of the paper N, the switch 16 first switches the variable color light emitting module 1 to the operating state.
Subsequently, the variable color light emitting module 1 is brought close to the paper N, and an external force F is applied to the elastic portion 11 of the variable color light emitting module 1.
At the same time, the pressure sensor 12 outputs a color change signal S1 to the color detection means 13 based on a change in the internal pressure of the elastic portion 11.
After the color detection means 13 receives the color change signal S1, the light is received and detected in a state in which the external light is applied to the paper N, and then the light is emitted from the light emitted by a method such as diffraction, scattering, reflection, or diffusion. While detecting the color wavelength of N, the color signal S2 corresponding to this wavelength is generated.
The processing means 17 sends a control signal S3 based on the color signal S2, and controls the light emitting means 14 to emit light corresponding to the color signal S2.

Therefore, the variable color light emitting module 1 detects the color of the object by the above-described device structure, and thus actively adjusts the color of the object so that the color of the color is approximately the same as or close to the wavelength emitted by the object. Achieving the purpose of emitting light.
In particular, since the operation is completed by a simple compression operation, the mood lighting apparatus has not only the response of the variable color light emitting module 1 becomes faster and more accurate, but also increases practicality and user's usage demand. It becomes.

It should also be noted that during actual operation, the pressure sensor 12 can have different variations depending on product needs or design considerations.
In the following, please refer to FIG. 4, which is a schematic diagram of the variation of the pressure sensor according to a preferred embodiment of the present invention.
Another structure of the pressure sensor 12 will be described as an example.

As shown in FIG. 4, the pressure sensor 12 includes an elastic member 121, a conductive member 122, and a switch element 123.
Among these, the elastic member 121 is coupled to the internal space of the elastic portion 11 and is used for sensing a pressure change in the internal space.
In practice, the elastic member 121 is an elastic material having conductivity. The switch element 123 is connected to the conductive member 122 and outputs a color change signal based on the pressure change in the internal space.

Please refer to FIG. 5, which is a schematic diagram of a variable color light emitting module 2 according to another embodiment of the present invention.
The variable color light emitting module 2 is different from the variable color light emitting module 1 in that the variable color light emitting module 2 includes a magnetic element 21 and a transmission unit 22.
In this embodiment, the magnetic element 21 is disposed on the outer surface of the housing 15, and when the variable color light emitting module 2 is mounted on the lamp holder, the magnetic reed switch of the lamp holder is activated to emit light from the lamp holder. It is for making it happen.
The transmission unit 22 is connected to the color detection unit 13 and the processing unit 17.
When the variable color light emitting module 2 is mounted on the lamp holder, the transmission means 22 transmits a color signal to the lamp holder, and causes the lamp holder to emit light with light corresponding to the color signal.
In practice, the transmission unit 22 may be a non-contact type transmission unit in addition to the contact type transmission unit described above.

Specifically, if the transmission means 22 is a contact-type transmission means, the transmission means 22 of the variable color light emitting module 2 receives the lamp holder when the variable color light emitting module 2 is accommodated in the accommodating space of the lamp holder. At this time, the transmitting means 22 transmits the color signal to the receiving means of the lamp holder, thereby causing the lamp holder to emit light with light corresponding to the color signal.
If the transmission means 22 is a non-contact transmission means, the processing means 17 receives the color signal sent from the color detection means 13 and then directly receives the color signal via the transmission means 22 in the lamp holder. By transmitting to the means, the lamp holder is caused to emit light with light corresponding to the color signal.
Of these, the non-contact type transmission means is preferably an infrared transmission means, but other wireless transmission techniques can also be used, and the present invention is not limited to this.

Further, regarding the transmission of the color signal, automatic transmission or manual transmission can be used in practice.
The so-called automatic transmission means that the color signal is immediately transmitted when the color detection means 13 generates a new color signal, and the manual transmission is a user's request whether or not the color signal is transmitted. This is based on the fact that the color signal is not transmitted unless the user activates a switch (not shown).

When the variable color light emitting module 2 is mounted in the housing space S of the lamp holder LS, the transmission means 22 of the variable color light emitting module 2 transmits a color signal to the lamp holder LS, and the lamp holder LS corresponds to the color signal. The light is emitted.
