Description of the invention: [Technical field to which the invention pertains] The present invention relates to a lighting device, and more particularly to a lighting device based on a carbon nanotube. [Prior Art] The lampshade used in the lighting device in the prior art has a cover structure or at least a flat or curved structure, and the cover covers the light source so that the light emitted from the light source is at least partially blocked by the light. However, the lampshade of the prior art does not have an audible or heat generating function. When the lighting device requires a sounding function, a separate thermosonic element, such as a speaker, is integrated with the lighting device: forming a sounding device. When the lighting device requires a heat generating function, a high-power light bulb is used instead of a light-emitting diode, a fluorescent lamp, or the like as a light source. • The structure of the ventilating illuminating device is relatively complicated. _ First: A kind of audible lighting device in the technology includes - light source and - hot sound, a few pieces of hot sound 70 pieces are integrated with the light source on a base. The thermoacoustic light can be respectively associated with an independent control circuit or a control circuit of the thermoacoustic element, and the control circuit of the light source is associated with the light source and the sound generation to achieve a certain purpose, such as a stage. In the lighting, the thermoacoustic components used in the vocal makeup device are electric, electromagnetic, electrostatic or piezoelectric according to their work. The reason is that the conversion of the vocalization of the thermoacoustic element used in the vocal lighting device in the former snow technology is to generate a sound by generating mechanical vibration to push the surrounding member = 2: the second space generates a wave. $Hot sound element:: Complex. The most widely used electric thermoacoustic component is 7 1362464. The thermoacoustic component usually consists of three parts: voice coil, magnet and diaphragm. The voice coil is usually powered by a conductor. When an audio current signal is input in the voice coil, the voice coil is equivalent to a current-carrying conductor. Since the current-carrying conductor will be subjected to Lorentz force in the magnetic field, the voice coil is placed in the magnetic field generated by the magnet. A force that is proportional to the audio current and whose direction changes with the direction of the audio current. Therefore, the voice coil vibrates under the magnetic field generated by the magnet and drives the diaphragm to vibrate. The vibration, the electrical signal is converted into sound waves to radiate around. This thermoacoustic component must work under magnetic conditions, and the structure of the audible lighting device using such thermoacoustic components is complicated.

When the carbon nanotube film structure comprises a plurality of layers of carbon nanotube film overlapping each other, the carbon nanotubes in the adjacent two layers of carbon nanotube film have an intersection angle α, and α is greater than or equal to 0 degrees. And less than or equal to 90 degrees. The larger the thickness of the carbon nanotube structure 1〇2, the better the low frequency effect and the higher the strength; the smaller the degree of the carbon nanotube structure 1〇2, the better the high frequency effect and the higher the sounding efficiency. Depending on the thickness of the carbon nanotube structure 102, the lampshade 1 〇〇 has a different frequency response range. The mountain* 佘 佘 碳 carbon tube structure 102 may further comprise one or more nanocarbon line-like structures. The nanocarbon line-like structure comprises at least one nano carbon: wire, the nano carbon line comprising a plurality of ends through a van der Waals force: a: U carbon tube segment 'each carbon nanotube segment comprises a plurality of lengths Nano-tubes that are substantially equal and parallel to each other. Similar to the structure of the carbon nanotube film, the structure of the carbon nanotubes is also different (4): wide, the nano-carbon pipeline-like structure is shown in step 4, and the structure of the nanocarbon pipeline is passed. Will take the carbon::::, 'line structure. The axial behavior of the carbon nanotube stranded structure is obtained, and the carbon nanotubes are helically arranged in the axial direction of the strand. It is understood that the carbon nanotube structure 14 • 102 can be a nano carbon pipeline. The structure is formed around the electrode, or is composed of a plurality of Nylon carbon pipeline structures or arranged side by side. In addition, the carbon nanotube structure 1G2 can be superposed by a carbon nanotube film and a nanocarbon pipeline structure. The length of the nanocarbon line-like structure is not limited, and the diameter is 0.5 nm to 1 mm. The electrode 104 is formed of a conductive material. Specifically, the electrode 1〇4 may be rod-shaped or rod-shaped. The spring material of the electrode 1〇4 may be selected from a hard material such as a metal, an alloy or a conductive polymer. Further, the electrode 104 may also be formed of an insulating material coated with a conductive material layer. In the first embodiment, the electrode 1〇4 is a metal rod whose length is substantially equal to the width of the carbon nanotube structure 102. When the carbon nanotubes in the carbon nanotube structure 102 are arranged in a certain direction Preferably, the nanocarbon The arrangement direction extends along one electrode to the other electrode 1〇4, and the electrodes should have a substantially equal spacing therebetween so that the carbon nanotubes between the two electrodes 104 can have a substantially equal resistance value. In the first embodiment, the carbon nanotubes are arranged substantially perpendicular to the length of the rod electrode 1〇4. Preferably, the length of the electrode 1〇4 is greater than the width of the carbon nanotube structure 1〇2. Therefore, the entire carbon nanotube structure 1〇2 can be utilized. The electrode 104 uniformly introduces an audio electric signal into the carbon nanotube structure 1〇2, and the carbon nanotube in the carbon nanotube structure 102 The electric energy is converted into heat energy, the surrounding medium is heated, and the density of the surrounding medium is changed to emit a sound. The medium may be a gas or a liquid. In addition, the electrodes 1 〇 4 may also be connected to a direct current, and the carbon nanotube structure 102 The electric energy is converted into heat under the action of direct current 15 1362464 - able to 'continue to emit heat. Since the electrodes 1〇4 are spaced apart, the lamp cover 1 can be operated while being connected to the stator to avoid short circuit. Carbon tube has The extremely large specific surface area 'the carbon nanotube structure=2 itself has good adhesion under the action of van der Waals force', so the electrode 1〇4 and the carbon nanotube structure 102 The electrode can be directly adhered and fixed, and a good electrical contact is formed. Alternatively, the electrode 1〇4 can be adhered and fixed to the surface of the carbon nanotube structure 102 by using a conductive bonding layer. The above carbon nanotube structure 102 has a smaller unit area heat capacity and a large specific surface area. Specifically, the carbon nanotube structure 1 〇 2 has a heat capacity per unit area of less than 2 x 1 〇 4 joules per square centimeter of Kelvin. In this embodiment, The carbon nanotube structure 1〇2 is a nano carbon tube film structure obtained directly from the carbon nanotube array, and has a smaller thickness, and the heat capacity per unit area of the carbon nanotube structure 102 is 17χ1. 〇·6 joules per square centimeter of Kelvin. When the illuminating device 10 is in use, after the input of the audio signal, according to the change of the signal strength (such as the current intensity), the lamp cover 100 composed of the carbon nanotube structure 1 〇 2 can uniformly heat the surrounding medium and rapidly rise and fall. And generating a periodic temperature change, and performing rapid heat exchange with the surrounding medium, so that the surrounding medium rapidly expands and contracts, and emits a sound that can be perceived by the human ear. Therefore, in the embodiment of the technical solution, the lamp cover in the lighting device 10 The principle of sound generation is the conversion of “electricity, heat and sound”, and the frequency of the sound emitted is wider and the sounding effect is better. As shown in FIG. 5, the carbon nanotube structure 102 formed by using the four-layer carbon nanotube film overlap arrangement is used for the sound intensity of the illumination device 1 可达 to a sound pressure level of 1 〇 5 dB, and the vocal frequency range is 丄 Hz to 1 〇 10,000 (ie 16 1362464 lHz ~ 100kHz). Since the carbon nanotube structure 102 has good light transmittance, it does not affect the light emitted from the light source to exit through the carbon nanotube structure 1〇2. • Referring to Fig. 8, the transmittance (light transmission ratio) of the carbon nanotube film is related to the thickness and density of the carbon nanotube film and the wavelength of light. When the thickness of the carbon nanotube film is 50 nm, the transmittance of the carbon nanotube film is ～82%, and the transmittance of green light having a wavelength of 550 nm is 78%. In addition, when the carbon nanotube film is stretched in a direction perpendicular to the alignment of the carbon nanotubes, the transmittance of the stretched carbon nanotube film can reach 84% to 92%. The carbon nanotube structure 102 has a good absorption effect on ultraviolet rays, and therefore, the globe 100 is disposed around the light source 110 to prevent ultraviolet radiation. It can be understood that the lamp cover 1 〇〇 and the light source u 中 in the illuminating device 10 can be respectively connected to the utterance circuit and the illuminating circuit. Alternatively, the lamp cover 1 and the light source 11A may be connected to an audible illumination mixing circuit which changes the illuminance or color of the light source 11 按 according to the vocal intensity or pitch of the lamp cover 1 。. It can be understood that the illumination device 1 can further include a signal source such as a DC source, an AC source or an audio source. The signal source is electrically coupled to the electrode 104. Referring to FIG. 6, a second embodiment of the present invention provides a lighting device 20 that includes a light source 210, a light cover 2A, and a bracket 22A. The light source 210 and the lamp cover 200 are disposed on the bracket 22, and the lamp cover 2 is disposed around the light source 210. The lampshade 200 includes a carbon nanotube structure 2〇2 and at least two electrodes 204 spaced apart from each other and electrically connected to the carbon nanotube structure 202. 17 1362464 The structure of the illuminating device 20 is substantially the same as that of the lighting device 10 of the first embodiment, except that the lamp cover 200 further includes a supporting structure 206, and the carbon nanotube structure 202 is disposed on the supporting structure 206. And supported by the support structure 206. The support structure 206 is supported by the bracket 220. The support structure 206 serves primarily as a support, having the shape of a lampshade or, in combination with the carbon nanotube structure 202, forming the shape of a lampshade. In particular, the support structure 206 can be a planar or curved structure and have a surface. At this time, the carbon nanotube structure 202 is directly disposed and attached to the surface of the support structure 206. Since the carbon nanotube structure 202 is integrally supported by the support structure 206, the carbon nanotube structure 202 can withstand a relatively high intensity audio signal input or direct current input, thereby having high sound intensity and heat generation performance. It will be appreciated that the support structure 206 can further be in the shape of a shade. Alternatively, the support structure 206 can be a frame structure, a rod structure or an irregular shape structure. At this time, the portion of the carbon nanotube structure 202 is in contact with the support structure 206, and the remaining portion is suspended. This arrangement allows the carbon nanotube structure 202 to be thermally exchanged with air or surrounding media. The carbon nanotube structure 202 has a larger contact area with air or surrounding medium, and has a faster heat exchange rate, thereby providing better sound generation efficiency. The material of the support structure 206 is an insulating material or a material having poor conductivity, and specifically may be a hard material such as diamond, glass, ceramic or quartz. In addition, the support structure 206 can also be a flexible material having a certain strength, such as plastic, resin, paper, fabric or other materials for the lampshade. The material of the support 18 1362464 • support structure 206 can be a transparent, translucent or opaque material.
