Description

Lighting device combined with algae cultivation

The present invention relates to a lighting device, in particular a lighting device with interactive adjustment function, and further relates to a cultivation device for promoting plant growth.

Algae is an important basic producer on Earth. It can be used as food, produce oxygen, purify water, deposit calcium carbonate, and assist in reef building. Currently, algae are mostly used as food or health care products on the market, and are rarely used for indoor planting. Among the popular indoor plants today, aquatic plants are gradually becoming popular. However, in existing cultivation devices, lamps are often only used to assist the growth of aquatic plants, and are rarely used as a source of ambient light. In addition, the components of general aquatic plant cultivation devices are complex and difficult to integrate into the environment.

According to the Republic of China's new patent certificate No. M545438, a lighting and cultivation device for aquatic plants is disclosed, in particular, a lighting and cultivation device for aquatic plants that can directly illuminate and effectively provide nutrients in water to improve its cultivation efficiency; the characteristics of the aquatic plant lighting and cultivation device created are that a light-emitting component is arranged in the accommodation space of the container of the cultivation device, and the light-emitting component uses a mutually encapsulated technology to make the circuit board, light-emitting element, control element and power supply element waterproof, and the light-emitting component is arranged at the center of the accommodation space and illuminates the surroundings to directly illuminate the aquatic plants arranged in the accommodation space to achieve the purpose of photosynthesis.

According to the Republic of China's new patent certificate No. M620423, a growth lamp and hydroponic box set is disclosed, specifically a mini desktop growth lamp and hydroponic box set; the feature of the mini desktop growth lamp and hydroponic box set of this invention is that it uses a specially designed integrated planting box and growth lamp, which meets all the needs of hydroponic planting, improves the conventional practice of separately setting growth lamps and hydroponic boxes, and miniaturizes them to meet the needs of indoor hydroponic plants. Therefore, this invention is a completely different mechanism from the conventional practice.

According to the Republic of China Invention Patent Publication No. 201316898, an LED desk lamp is disclosed, particularly a lamp with a replaceable light source, a transparent cultivation chamber, and a conductive telescopic bracket for experimental purposes of plant cultivation; the LED desk for plant cultivation of the invention enhances the application of teaching experiments, and uses the operation of the dimmable LED light set of the desk lamp to project light onto the plants built into the transparent cultivation chamber, and uses the conductive telescopic bracket to adjust the height and angle of the dimmable LED light set projected onto the plants built into the transparent cultivation chamber.

In summary, although miniaturized indoor plant cultivation lighting devices have been disclosed in the prior art, these lighting devices lack interaction mechanisms with cultivation devices, and the cultivation device components are complex, which will lead to inconvenience in plant cultivation management; in addition, these lighting devices lack automatic adjustment mechanisms for light intensity and light wavelength, and must be adjusted manually by personnel, with low feedback on plant growth status; and because the cultivation device has complex components, it is not easy to disassemble, assemble, replace or randomly adjust its relative position with the lighting device, and has low interaction with personnel, and cannot naturally integrate into the indoor environment where personnel are located.

In this embodiment, its basic components and specific operation methods are the same as those of the first embodiment, except that the base (1) includes an annular shield (11a), an annular shell (12a), a bottom plate (13a) and a fixed bracket (14a); the annular shield (11a) is arranged on the annular shell (12a), and the annular shell (12a) is provided with On the chassis (13a), the central parts of the annular cover (11a) and the annular outer shell (12a) are connected to form a receiving space (Sa), and the fixing bracket (14a) is arranged in the receiving space (Sa) to fix the supporting body (21); in some specific embodiments, the chassis (13a) is further provided with a plurality of locking holes (131) so that the user can use a matching lock (not shown) to lock the lighting device (100) to a wall, a floor or a ceiling to achieve an indoor lighting effect.

When the control element ( 22) determines that the concentration information is greater than or equal to the preset value of the carbon dioxide concentration, the control element (22) outputs a first brightness adjustment signal to increase the brightness of the light-emitting body (212); when the control element (22) determines that the concentration information is less than the preset value of the carbon dioxide concentration, the control element (22) outputs a second brightness adjustment signal to reduce the brightness of the light-emitting body (212); in some embodiments, the carbon dioxide concentration The carbon dioxide concentration sensor (24) can be arranged in the base (1), or can be arranged in conjunction with the photosynthetic zone (213) to sense changes in carbon dioxide concentration around the lighting device (100). It can be understood that after the algae in the algae culture vessel (3) have been cultured for a period of time, the increase in algae biomass leads to an increase in carbon dioxide consumption around the lighting device (100), and the control element ( 22) The change in carbon dioxide concentration can be used to determine whether the algae biomass has increased, thereby reducing the light transmittance of the algae culture vessel (3).

Generally speaking, photosynthesis of different algae mainly relies on different types of photosynthetic pigments. The most common types of photosynthetic pigments are chlorophyll, carotenoids and phycobilin. Chlorophyll is not the only pigment that plays a role in photosynthesis, and the contribution of other pigments to photosynthesis efficiency must also be considered. Different algae have different types and proportions of photosynthetic pigments, so photosynthesis is not the only factor that affects photosynthesis. The efficiency of use cannot only consider the absorption spectrum of chlorophyll; for example, green algae contain more chlorophyll including chlorophyll a and/or chlorophyll b, among which chlorophyll a absorbs light at a wavelength of 400 to 450nm or 630 to 660nm, and chlorophyll b absorbs light at a wavelength of 450 to 480nm; red algae and brown algae have more phycobilins including phycoerythrins (PEs), phycoerythrin (Ph ycoerythrocyanins (PECs), phycocyanins (PCs) and/or allophycocyanins (APCs), wherein the absorption wavelength of phycoerythrin is 480 to 580 nm, the absorption wavelength of phycoerythrocyanin is 480 to 580 nm, the absorption wavelength of phycocyanin is 600 to 640 nm, the absorption wavelength of allophycocyanin is 6 20 to 660nm; diatoms contain chlorophyll including chlorophyll a and/or chlorophyll c, and carotenoids including α-carotene, β-carotene and/or lutein, among which chlorophyll c absorbs light at a wavelength of 440 to 520nm, α-carotene absorbs light at a wavelength of 400 to 500nm, β-carotene absorbs light at a wavelength of 450 to 475nm, and lutein absorbs light at a wavelength of 440 to 450nm.

In a specific embodiment, after the sensing light-emitting module (2) activates the light-emitting body (212) to emit light, the reflected light of the algae culture vessel (3) is detected by the optical sensor (25), and the type of algae in the algae culture vessel (3) is determined by comparing the absorption light spectrum value through the control element (22), and then a corresponding wavelength adjustment signal is issued to adjust the wavelength of the emitted light of the light-emitting body (212); for example, when green algae are cultured in the algae culture vessel (3), the optical sensor (25) detects that the reflected light is mainly blue-green, and its output wavelength information is between 450 and 520 nm, and the control element (22) After comparing the wavelength information, the corresponding photosynthetic pigment is captured as chlorophyll a, and the corresponding first wavelength adjustment signal is output to indicate that the light emitting body (212) emits chlorophyll a absorption light with a wavelength of 400 to 450nm or 630 to 660nm, or the optical sensor (25) detects that its reflected light is mainly yellow-green, and its output wavelength information is between 520 and 580. After comparing the wavelength information, the control element (22) captures the corresponding photosynthetic pigment as chlorophyll b, and outputs the corresponding second wavelength adjustment signal to emit chlorophyll b absorption light with a wavelength of 450 to 480nm, but is not limited thereto.

In some preferred embodiments, the wavelength information includes a first wavelength information and a second wavelength information, and the luminance ratio of the first wavelength information to the second wavelength information is x, which is an arbitrary value greater than 0. When the control element (22) determines that the first wavelength information is equal to the first absorption light spectrum value, and determines that the second wavelength information is equal to the second absorption light spectrum value, when the luminance ratio x is greater than 1, the control element (22) outputs the first wavelength adjustment signal to activate the light emitting body (212) to emit the first absorption light, and when the luminance ratio x is less than 1, the control element (22) outputs the second wavelength adjustment signal to activate the light emitting body (212) emits the second absorbed light. When the light intensity ratio is equal to 1, the control element (22) outputs a third wavelength modulation signal to activate the light emitting body (212) to emit the first absorbed light and the second absorbed light. For example, when diatoms are cultured in the algae culture vessel (3), the optical sensor (25) detects that the reflected light is blue-green and orange-yellow, and the output first wavelength information is between 450 and 520 nm and the second wavelength information is between 590 and 630 nm. After comparing the wavelength information, the control element (22) captures the corresponding photosynthetic pigments as chlorophyll a and carotenoids. When the control element (22) determines that When the light intensity ratio is greater than 1, it is judged that the chlorophyll a content is greater than carotenoids, that is, a corresponding first wavelength modulation signal is output to indicate that the light emitting body (212) emits chlorophyll a absorption light with a wavelength of 400 to 450nm or 630 to 660nm; or when the control element (22) judges that the light intensity ratio is less than 1, it is judged that the chlorophyll a content is less than carotenoids, that is, a corresponding second wavelength modulation signal is output to indicate that the light emitting body (212) emits carotenoid absorption light with a wavelength of 400 to 500nm, 450 to 475nm or 440 to 450nm; or when the control element (22) judges that the light intensity ratio is equal to 1, the light emitting body (212) emits chlorophyll a absorption light with a wavelength of 400 to 500nm, 450 to 475nm or 440 to 450nm; When the chlorophyll a content is determined to be the same or similar to the carotenoid content, a corresponding third wavelength modulation signal is output to instruct the light emitter (212) to emit the absorption light of chlorophyll a and carotenoid at the same time, which can be exemplified by chlorophyll b absorption light of 400 to 450 nm with 450 to 480 nm, 400 to 450 nm with 450 to 475 nm, 400 to 450 nm with 440 to 450 nm, 630 to 660 nm with 450 to 480 nm, 630 to 660 nm with 450 to 475 nm, 630 to 660 nm with 440 to 450 nm, but not limited thereto.
