Description

Technical Field

[0001] The invention relates to the field of light-emitting diode lighting, and in particular to a graphene composite photon diode light source. Background Art

[0002] A light-emitting diode is a special diode that consists of a P-pole and N-pole junction structure formed by processes such as semiconductor material doping. When different electrode voltages are applied, current flows from the P-pole to the N-pole, and different carrier holes and electrons meet and recombine, causing the electrons to fall to a lower energy level and release energy in the form of photons. Light of different wavelengths corresponds to different photons and energies.

[0003] Currently, light-emitting diodes are widely used in many fields due to their small size, low power consumption, long life, and environmental protection. However, their light-emitting principle determines that a single light-emitting diode can only emit photons of a single band, and its spectrum is limited to the visible light and near-infrared range.

[0004] However, light sources used in new bioenergy, indoor planting, medical beauty skin care, medical physiotherapy and other fields often require the composite effect of photon energy in multiple different bands, and some applications require the use of photon energy in the far-infrared band, and require the ability to autonomously adjust the proportion of photon energy in different bands emitted, as well as control the amount of thermal radiation emitted by the light source. Currently, there is a lack of an effective composite photon luminescent light source for these applications.

[0005] In view of the above problems, the present invention aims to design a graphene composite photon light emitting diode light source by combining the physical and chemical properties of graphene, a new type of carbon material. Graphene is an emerging carbon material, which is composed of carbon atoms arranged in a hexagonal lattice to form a single-layer two-dimensional honeycomb-like plane structure. Electrons can move at high speed in the material, and it has excellent mechanical, thermal, optical and electrical properties. The Young's modulus can reach 11,000GPa, the fracture strength can reach 125GPa, the thermal conductivity can reach 5,000W / (m·K); the carrier mobility can reach 200,000cm 2 / V·s. Its two-dimensional planar lattice structure allows electrons to flow freely, achieving excellent electrical and thermal conductivity. When two levels of electricity are turned on, the electron temperature can be much higher than the acoustic vibration mode of the graphene lattice, and it can continuously maintain the excited state and efficiently release infrared photons in the 5 to 18 micron band. Summary of the invention

[0006] The present invention provides a graphene composite photon diode light source, which at least solves the problems of single photon energy band and limited luminous spectrum emitted by light-emitting diodes in the prior art, and can emit effectively mixed composite photon energy, and can autonomously adjust the proportion of photon energy in different bands, and release controllable thermal radiation energy. It can be widely used in new bioenergy, indoor planting, medical beauty and skin care, heating and lighting, medical physiotherapy and other fields.

[0007] The present invention is implemented through the following technical solutions, including: an insulating base for integrated packaging, the inner wall of the insulating base is a concave three-dimensional structure; a columnar negative electrode, the columnar negative electrode is located at the center of the inner wall of the insulating base, and the horizontal plane can be slightly depressed or raised to form a staggered layer; a light-emitting diode chip, the light-emitting diode chip is mounted on the columnar negative electrode, including one or more light-emitting diode wafers of different bands; a graphene film, the graphene film is laid on the inner wall of the insulating base; a silicone lens, the silicone lens is mounted on the upper end of the insulating base; silicone, the silicone is used to encapsulate the devices in the insulating base and is integrated with the silicone lens.

[0008] Furthermore, the inner wall of the insulating base described in the present invention is designed based on a concave three-dimensional structure, which can be a hemispherical concave surface, a concave concave surface, or a three-dimensional structure of a concave surface spliced ​​with multiple planes. The points on the concave surface, or the lines connecting the center points of the multiple planes and the set intersection area are respectively perpendicular to the tangent planes or planes of the corresponding concave points, so that the light and heat radiation emitted from the inner wall of the insulating base form a convergence effect in the set intersection area.

[0009] Furthermore, the bottom of the light emitting diode chip of the present invention is provided with a heat dissipation base plate, one end of which is connected to the columnar negative electrode, and the other end is connected to the resistor and the positive electrode.

[0010] Furthermore, the graphene film described in the present invention is laid on the inner wall of the insulating base, and its structure is a three-layer sandwich structure: an upper insulating protection layer, a middle graphene film layer, and a lower insulating protection layer.

[0011] Furthermore, the insulating protective layer of the present invention may be a resin pad, such as silicone resin, polyurethane resin, or silica gel, which plays the role of insulating, shaping, and protecting the graphene film layer.

[0012] Furthermore, the preparation methods of the graphene film layer described in the present invention are relatively diverse. The graphene film can be prepared by chemical vapor deposition, or by vacuum filtration, spin coating, or evaporation of a dispersion containing graphene powder to form a graphene film on a filter membrane or a carrier. A certain amount of infrared emitter can be added as needed.

[0013] Furthermore, the graphene film of the present invention excites electrons through an electric heating method to generate photons and thermal radiation in the infrared band of 5 to 18 microns, and can release thermal radiation uniformly in a planar manner.

[0014] Furthermore, a heat-insulating reflective layer is provided between the graphene film of the present invention and the inner wall of the insulating base to prevent the photons and heat radiation generated by the graphene film from being emitted to the outside.

[0015] Furthermore, the resistors described in the present invention are variable resistors of different types, and the current of the light-emitting diode chip and the graphene film is changed by controlling their resistance values, thereby changing the radiant flux of each band of light emitted by them, and controlling the proportion of photon energy of each band in the composite photon, thereby controlling the spectrum of the composite photon light source.

[0016] Furthermore, the photons and thermal radiation released by the graphene film of the present invention and the photons of different wavelengths released by the light-emitting diode chip can be converged at the set intersection area through the concave three-dimensional structure of the inner wall of the insulating base, and then dispersed through the silicone lens after mixing.

[0017] Furthermore, the silicone lens of the present invention can be molded into lenses of different shapes, including spherical, cylindrical, elliptical, gourd-shaped, etc., for focusing light or adjusting the emission angle of light.

[0018] The beneficial effect of the present invention is that it utilizes the characteristics of graphene film and the combination of light-emitting diode chips of different bands, so as to realize the emission of mixed composite photons from the visible light band to the infrared band and thermal radiation through a single component, and can autonomously adjust the proportion of photon energy in different bands according to needs, so that the light source can better act on plants, tissue cells, organisms, human body parts, etc., and can be widely used in new bioenergy, indoor planting, medical beauty skin care, heating lighting, medical physiotherapy and other fields.
