Description

Technical Field

[0001] The invention relates to the technical field of plasma lamps, in particular to a device for indoor plant lighting and breeding and a plasma lamp. Background Art

[0002] When planting crops outdoors, there are climate change issues such as accidents or extreme weather, which may lead to insufficient light intensity and short duration, affecting plant growth rate and yield. Similarly, when breeding and cultivating new varieties of crops such as wheat and rice, multiple generations of hybridization and multiple cycles of planting are required, which often takes several years. The long cycle limits the rapid breeding process of crops. Using artificial light indoors to promote plant photosynthesis can be used as a way to solve the adverse environmental conditions of outdoor planting and accelerate breeding.

[0003] Outdoors, plants photosynthesize with sunlight, but indoors, the current light sources for plant lighting, such as LEDs and high-pressure sodium lamps, are different from the solar spectrum distribution. The difference is that they cannot provide continuous spectrum lines in the full range of 280nm to 2500nm, especially the spectrum lines of ultraviolet and near-infrared wavelengths are missing. UVB ultraviolet rays in sunlight cannot penetrate glass and plastic, and indoor supplementary lighting LEDs and sodium lamps generally do not output UV-B. However, studies have found that ultraviolet light promotes gene regulation, flavonoid synthesis, reduction of infectious pathogens and protein synthesis in plants, and can increase the nutritional value and taste of food. Therefore, the use of artificial light sources that simulate sunlight has great advantages in plant growth and breeding.

[0004] Plasma light sources can emit a continuous spectrum from ultraviolet to infrared, similar to sunlight, and have great advantages in plant growth and breeding. At present, some plasma lamps have appeared in the market, but due to the need for heat dissipation of components such as RF drivers, resonant cavities and bulbs, these plant lighting plasma lamps mostly enclose components such as DC power supplies, RF drivers and bulbs in a cavity space for waterproofing to form an integral lamp. However, the heat generated by various components in the same cavity can cause cross-heat conduction. For example, when the bulb is working, the temperature is above 700 degrees, and the resonant cavity is around 120 degrees. These two high-temperature heating elements can easily conduct heat and light to the RF driver and DC power supply through the metal shell of the lamp, causing the temperature of electronic components to rise and reduce life. Or, for example, the heat of the RF driver is conducted to the DC power supply, reducing the life of the power supply. In order to reduce the temperature of the RF driver and power supply, the volume of the radiator can only be increased, resulting in the general increase in the volume and weight of the lamp, which is not easy to install. A 300W plasma lamp weighs about 10kg. In addition, the increase in volume and weight requires the use of more heat dissipation materials, which also brings the problem of high prices, affecting large-scale promotion and application.

[0005] In addition, when used as a light source to illuminate plants in a greenhouse, conventional lamps such as LED light sources are composed of many light-emitting diodes. In order to obtain high illumination, the LED bulbs can only be used to illuminate the plants at a close distance. As the distance increases, the illumination drops sharply due to the non-concentrated light distribution. The LED lamp beads must be tightly connected to the heat dissipation aluminum plate to avoid light decay and work normally. In this way, the heat generated by the LED light source is directly discharged into the room at a close distance, causing the temperature to rise, and air conditioning has to be used for cooling. The air conditioning to maintain the ambient temperature also consumes a lot of energy.

[0006] Therefore, it is necessary to develop a small and lightweight plasma lamp for indoor plant lighting and breeding, as well as a heat dissipation installation method for indoor plant lighting, which can reduce the impact of lamp heat on the ambient temperature in the greenhouse.

[0007] In the prior art, the invention patent with the patent publication number CN102915905A discloses a plasma lamp with a radio frequency heating device. In order to solve the problem that the life of the entire plasma lamp is restricted by the short service life of the magnetron, the patent uses the method of separating the AC / DC power converter, the radio frequency power amplifier, the resonant cavity and the bulb. The DC power output by the AC / DC power converter with a constant voltage supplies power to the radio frequency power amplifier. The radio frequency power amplifier excites radio frequency energy in the public frequency band and transmits it to the plasma gas resonant cavity through a waveguide. The middle of the resonant cavity is the support rod of the plasma bulb and the inside of the resonant cavity is hollow. The radio frequency energy resonates in the resonant cavity to generate energy to heat the plasma bulb. The inert gas in the plasma bulb is excited to emit light in a plasma state, thereby extending the service life of the plasma lamp. This patent only separates components such as the light source. Component separation does not mean heat separation. Although the plasma lamps currently on the market are separated by multiple components, when the lamp is assembled, multiple components are put together, and the heat generated by each component is superimposed on each other, reducing the heat dissipation efficiency. As shown in the attached Figure 1 All components shown in one housing for a 230W plasma lamp, with Figure 2 The R400 plasma lamp shown has all components inside a housing, which causes cross-conduction of heat, increasing the heat sink and weight of the lamp. Summary of the invention

[0008] The technical problem to be solved by the present invention is to solve the problem of heat conduction when plasma is used as a whole lamp.

[0009] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0010] A plasma lamp comprises a resonant cavity heat sink 10, a light emitting component 20, a radio frequency driven heat sink 30, a direct current power supply 40, and a thermal isolation plate 50; according to the working temperature and heat dissipation requirements of each component, the resonant cavity device 10 and the light emitting component 20 are arranged in one accommodation space by adopting a heat separation method; the radio frequency driven heat sink 30 and the direct current power supply 40 are arranged in another accommodation space, and the resonant cavity heat sink 10 is connected to the radio frequency driven heat sink 30 by wires;

[0011] Among them, the light-emitting component 20 is arranged at the front end of the resonant cavity heat sink 10, and the thermal isolation plate 50 is arranged between the RF driven heat sink 30 and the DC power supply 40; the plasma lamp also includes a horizontal connecting plate 60, and the two ends of the horizontal connecting plate 60 are respectively fixedly connected to the resonant cavity heat sink 10 and the RF driven heat sink 30.

[0012] In one embodiment of the present invention, the resonant cavity heat dissipation device 10 includes a resonant cavity 11 and sunflower heat dissipation fins 12 ; the sunflower heat dissipation fins 12 wrap the resonant cavity 11 and are coaxial with the resonant cavity 11 .

[0013] In one embodiment of the present invention, the light emitting assembly 20 includes a light emitting body 21 and a reflector 22; the reflector 22 is arranged at the front end of the resonant cavity 11, and the light emitting body 21 is located in the reflector 22 and connected to the inner conductor 111 at the front end of the resonant cavity 11.

[0014] In one embodiment of the present invention, the RF drive heat dissipation device 30 includes an RF driver 31 and a dense-toothed heat sink 32; the RF driver 31 is located below the dense-toothed heat sink 32, and the dense-toothed heat sink 32 and the thermal isolation plate 50 are combined to enclose the RF driver 31; and the heat dissipation fins of the dense-toothed heat sink 32 are upward.

[0015] In one embodiment of the present invention, the DC power supply 40 and the RF driver 31 are arranged back to back in a longitudinal direction.

[0016] The present invention also provides a device for indoor plant lighting and breeding, comprising the plasma lamp described in any one of claims 1-5; the light-emitting component 20 is arranged in a greenhouse 100, and the resonant cavity heat dissipation device 10, the radio frequency driven heat dissipation device 30, the direct current power supply 40, the thermal isolation plate 50, and the horizontal connecting plate 60 are all arranged outside the greenhouse 100.

[0017] In one embodiment of the present invention, the plasma lamp is fixed on the top of the greenhouse 100 , and the light-emitting component 20 is operated in the greenhouse 100 through a first reserved opening provided at the top of the greenhouse 100 .

[0018] In one embodiment of the present invention, a hollow tube 200 is suspended in the greenhouse 100, with both ends of the hollow tube 200 open and located outside the greenhouse 100, a plasma lamp is arranged in the hollow tube 200, and a second reserved opening is arranged in the hollow tube 200, and the light-emitting component 20 works in the greenhouse 100 through the second reserved opening.

[0019] In one embodiment of the present invention, an air cooling device 300 is disposed at one end of the hollow tube 200 .

[0020] In one embodiment of the present invention, a plurality of plasma lamps are arranged in series in the hollow tube 200 ; in winter, two ends of the hollow tube 200 are introduced into the greenhouse 100 from outside the greenhouse 100 .

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The largest heat sources in plasma lamps are the resonant cavity and the RF driver, of which the RF driver accounts for about 40% of the heat, while the heat generated by the resonant cavity accounts for 50% of the total heat, and the heat generated by the DC power supply accounts for about 10% of the total heat. The operating temperature of the luminous body bulb is above 700 degrees, and high temperature is required to achieve the best luminous efficiency. The resonant cavity allows high temperature operation of 120 degrees, while the operating temperature of components such as the RF driver and DC power supply is only allowed to be below 85 degrees.

[0023] The advantage of the present invention is that it utilizes the characteristics of the operating temperature of each component. The resonant cavity and the RF driver are located in different spaces. The RF loss of the resonant cavity and the high-temperature heat generated by the light-emitting body are directly dissipated upward through the sunflower heat dissipation fins extruded from aluminum alloy materials, avoiding the problem of excessive temperature being caused by transmission to the RF driver in the same space, resulting in reduced efficiency and shortened life.

[0024] The heat of the RF driver is directly dissipated upward into the air through the dense-tooth heat sink, and the heat generated by the DC power supply is dissipated directly into the air through the U-shaped thermal isolation plate to avoid direct heating of the RF driver, thereby directly dissipating the heat of each other into the air, avoiding the problem of heat cross-contamination and conduction causing the temperature of the RF driver to rise, thereby reducing the demand and weight of the heat sink. At the same time, the DC power supply is located below the RF driver, with a back-to-back structure, which reduces the lateral volume of the plasma lamp. The reflector is located at the front end of the resonant cavity and the light source, and also has the effect of shielding electromagnetic interference.

[0025] Since the heat of the resonant cavity and the RF driver is directly dissipated into the air, cross-conduction of heat is avoided, and the size and weight of the radiator required by the RF driver are reduced, reducing the problem of high equipment and installation prices, and is suitable for large-scale promotion and application. The present invention can reduce the weight of a 300W plasma lamp to less than 4kg, greatly reducing the weight. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] To facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention is further described in conjunction with the accompanying drawings.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] Example 1

[0034] See also Figure 3 As shown, the present invention provides a plasma lamp, including a resonant cavity heat sink 10, a light-emitting component 20, a radio frequency driven heat sink 30, a direct current power supply 40, and a thermal isolation plate 50. According to the operating temperature and heat dissipation requirements of each component, a heat separation method is adopted, and the resonant cavity device 10 and the light-emitting component 20 are arranged in one accommodation space, and the radio frequency driven heat sink 30 and the direct current power supply 40 are arranged in another accommodation space. The resonant cavity heat sink 10 is connected to the radio frequency driven heat sink 30 by wires, the radio frequency driven heat sink 30 is connected to the direct current power supply 40 by wires, and the thermal isolation plate 50 is arranged between the radio frequency driven heat sink 30 and the direct current power supply 40. In this embodiment, the two accommodation spaces can be understood as two shells.

[0035] See also Figure 3 and Figure 4As shown, in one embodiment of the present invention, the resonant cavity heat dissipation device 10 includes a resonant cavity 11 and a sunflower heat dissipation fin 12. The sunflower heat dissipation fin 12 wraps the resonant cavity 11 and is coaxial with the resonant cavity 11.

[0036] In this embodiment, the light emitting assembly 20 is disposed at the front end of the resonant cavity heat sink 10. Specifically, the light emitting assembly 20 includes a light emitting body 21 and a reflector 22, the reflector 22 is disposed at the front end of the resonant cavity 11, and the light emitting body 21 is located in the reflector 22 and connected to the inner conductor 111 at the front end of the resonant cavity 11, so that the reflector also plays the effect of shielding electromagnetic interference.

[0037] In this embodiment, the RF drive heat dissipation device 30 includes an RF driver 31 and a dense-tooth radiator 32, wherein the RF driver 31 is located below the dense-tooth radiator 32, and the dense-tooth radiator 32 and the thermal isolation plate 50 are combined to enclose the RF driver 31, and the heat dissipation fins of the dense-tooth radiator 32 are facing upward. The thermal isolation plate 50 is an aluminum plate with a U-shaped design, which surrounds and wraps the RF driver 31 by cooperating with the bottom plate of the dense-tooth radiator 32. The DC power supply 40 is arranged below the thermal isolation plate 50 to achieve thermal isolation from the RF driver 31. In addition, the RF driver 31 is connected to the resonant cavity 11 through a RF coaxial cable, and the RF driver 31 is electrically connected to the DC power supply 40.

[0038] In this embodiment, the heat of the RF driver 31 is directly dissipated upward into the air through the dense-tooth heat sink 32, and the heat generated by the DC power supply 40 is isolated by the heat isolation plate 50 to avoid direct heating of the RF driver 31, so that the heat of each is directly dissipated into the air, avoiding the problem of heat cross-contamination and conduction causing the temperature of the RF driver 31 to rise, thereby reducing the demand and weight of the heat sink. In addition, the DC power supply 40 and the RF driver 31 are arranged back to back longitudinally, which reduces the lateral volume of the plasma lamp.

[0039] In this embodiment, since most of the current plasma lamps integrate multiple components such as the resonant cavity 11, the RF driver 31, the coaxial cable and the light-emitting body 21, especially the DC power supply 40, the high-temperature light-emitting body 21 and the RF driver 31 are installed in the same space, the heat cannot be dissipated, and the heat of each component cross-conducts with each other, affecting the life, requiring a larger radiator volume. The present invention, based on the characteristics of the working temperature and heat dissipation requirements of each component, separates the components that need to work at high temperatures, such as the light-emitting body 21 and the resonant cavity 11, from the components that need to work at lower temperatures, such as the RF driver 31 and the DC power supply 40, by heat separation, thereby avoiding the problem of large radiator volume and heavy weight of the current lamps due to heat cross-conduction. However, such a heat separation design is not convenient for subsequent transportation and installation, because the components of the lamp are divided into two parts, not a whole, and the user needs to assemble them by himself when using them, and it is not convenient to install or use a hook when using and installing them on the plant lighting site. In order to solve this problem. The plasma lamp of the present invention further comprises a horizontal connecting plate 60, and the two ends of the horizontal connecting plate 60 are respectively fixedly connected to the resonant cavity heat sink 10 and the RF drive heat sink 30. Specifically, the two ends of the horizontal connecting plate 60 are respectively connected to the resonant cavity 11 and the dense tooth heat sink 32. The two separated parts of the plasma lamp are connected into a whole through the horizontal connecting plate 60, so that the user can avoid installation. More specifically, a hook installation port is provided on the flat connecting plate 60, and the hook installation port is close to the side of the RF drive heat sink 30. In this way, when the plasma lamp is subsequently installed and fixed, the hanging tool can be hung on the hanging port to realize the hanging of the plasma lamp.

[0040] See also Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the principle of the present invention is that an AC power supply generates a constant voltage through a DC power supply 40, and the constant voltage is between 24V and 50V, which is supplied to an RF driver 31. The RF driver 31 generates RF microwave energy of several hundred MHz, which is input into the resonant cavity 11 through a coaxial cable, and excites the gas discharge in the light-emitting body 21 at the front end of the inner conductor 111 in the resonant cavity 11, forming a high-density plasma light emission.

[0041] In one embodiment of the present invention, the principle of heat separation of the components of the plasma lamp of the present invention is that the largest heat sources in the plasma lamp are the resonant cavity 11 and the RF driver 31, of which the RF driver 31 accounts for about 40% of the heat, while the heat generated by the resonant cavity 11 accounts for 50% of the total heat, and the heat generated by the DC power supply 40 accounts for about 10% of the total heat. The operating temperature of the luminous body 21 is above 700 degrees, and high temperature is required to achieve the best luminous efficiency. The resonant cavity 11 allows high temperature operation of 120 degrees, while the operating temperature of components such as the RF driver 31 and the DC power supply 40 is only allowed to be below 85 degrees.

[0042] The advantage of the present invention is that it utilizes the characteristics of the working temperature of each component. The resonant cavity 11 and the RF driver 31 are located in different spaces. The RF loss of the resonant cavity 11 and the high-temperature heat generated by the light-emitting body 21 are directly dissipated upward through the sunflower heat dissipation fins 12 extruded from aluminum alloy materials, avoiding the problem of excessive temperature being transmitted to the RF driver 31 in the same space, resulting in reduced efficiency and shortened life.

[0043] Example 2

[0044] See also Figures 3 to 6 As shown, the present invention also provides a device for indoor plant lighting and breeding, including the plasma lamp described in Example 1. The light-emitting assembly 20 is arranged in the greenhouse 100, and the resonant cavity heat sink 10, the radio frequency drive heat sink 30, the DC power supply 40, the thermal isolation plate 50, and the horizontal connecting plate 60 are all arranged outside the greenhouse 100. When used for plant lighting and breeding indoors, the plasma light source has the advantages of small light volume and easy convergence into a concentrated light spot to illuminate the plants. When irradiating the plants at a long distance, the heat of the resonant cavity 11 and the radio frequency driver 31 is directly discharged to the outside to avoid the generated heat affecting the environment of the indoor plants and reduce the energy consumption of air conditioning.

[0045] See also Figures 3 to 5 As shown, in one embodiment of the present invention, the plasma lamp is fixed on the top of the greenhouse 100, and the light emitting assembly 20 is provided through a first reserved opening on the top of the greenhouse 100 to work in the greenhouse 100. In this embodiment, the heat generated by the resonant cavity 11 and the radio frequency driver 31 of the plasma lamp is directly discharged to the external space, which will not affect the growth environment of the plants in the greenhouse 100, avoid the indoor temperature from rising, and on the other hand reduce the air conditioning energy consumption required to maintain the temperature in the greenhouse 100. Figure 5 As just one example, in a large plant growing room or cabin, dozens of plasma lamps of the present invention can be placed to significantly reduce energy consumption. Plasma lamps are arranged on the top of the greenhouse 100, which is suitable for the case where the height of the greenhouse 100 is appropriate. If the greenhouse 100 is too high, the irradiation effect will be affected.

[0046] Example 3

[0047] See also Figure 3 , 4 and Figure 6As shown, in another embodiment of the present invention, it is suitable for the case where the longitudinal dimension of the greenhouse 100 is high. A hollow tube 200 is suspended in the greenhouse 100, and both ends of the hollow tube 200 are open and located outside the greenhouse 100. The plasma lamp is arranged in the hollow tube 200, and a second reserved opening is arranged in the hollow tube 200. The light-emitting component 20 works in the greenhouse 100 through the second reserved opening. An air cooling device 300 is arranged at one end of the hollow tube 200. Specifically, the air cooling device 300 is a fan or an axial flow fan. The high-speed airflow of the fan or the axial flow fan is used to directly and actively cool the resonant cavity 11 and the radio frequency driver 31 in the hollow tube 200, and the heat is blown into the atmosphere from the other port. Similarly, the heat dissipation method of the present invention avoids the heat transfer of the lamp into the greenhouse, reduces the influence of the heat dissipation of the lamp on the ambient temperature of the greenhouse, and on the other hand, reduces the energy consumption required for air conditioning refrigeration.

[0048] In one embodiment of the present invention, a plurality of plasma lamps are arranged in series in the hollow tube 200; in winter, the two ends of the hollow tube 200 are introduced into the greenhouse 100 from outside the greenhouse 100, such as splicing ventilation pipes at the ends of the hollow tube 200 to introduce into the greenhouse 100. In summer, the air cooling device 300 discharges heat to the outside of the greenhouse 100. In winter, the heat loss of the plasma lamp is used to maintain the temperature in the greenhouse 100, which also plays a role in greatly reducing the energy consumption of air conditioning.
