Description

Technical Field

[0001] The utility model relates to the technical field of LEDs, and in particular to a mixed-light plant lighting lamp bead and a lamp. Background Art

[0002] Light is an indispensable source of energy for green plants to carry out photosynthesis. Only under light conditions can plants grow normally. Plant photosynthesis refers to the process by which plants absorb sunlight energy with the help of chlorophyll, synthesize carbon dioxide and water into organic matter, and further convert it into chemical energy for storage, while releasing oxygen. The carbohydrates produced by photosynthesis are further converted into starch, fat, etc. for life activities. In short, the influence of light on plants is crucial. In order to promote the growth of plants, people will place lamps in greenhouses or indoors.

[0003] Plants need different wavelengths of light to grow, so existing plant lighting strips need to attach lamp beads of different wavelengths to a light strip to light up and emit different lights to promote plant growth and absorption. Since a single lamp bead can only emit light of the same wavelength, it is too simple and has low versatility. The application of lamp beads is limited. Different wavelengths of light require different lamp beads, so users need to customize a variety of lamp beads according to their needs and set them on the light strip, which is inefficient and costly.

In addition, by providing multiple accommodating grooves of different volumes, the number of chips in the chipset in the accommodating grooves of different volumes is different, and the intensity ratio between lights of different wavelengths can be further adjusted, and the emphasis ratio between different wavelengths required by different plants is the same. Such a design enables the lamp bead to adapt to the growth needs of different plants, further improving the versatility of the lamp bead.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] See also Figures 1 to 3 , shown is a mixed light plant lighting lamp bead in the first embodiment of the utility model, including a bracket 41 and a plurality of chipsets 20 arranged on the bracket 41, wherein:

[0028] The bracket 41 is provided with a mounting groove 11 for placing the chipset 20. The mounting groove 11 has a plurality of longitudinal partitions 30 that divide the mounting groove into a plurality of receiving grooves 12. The plurality of chipsets 20 are respectively arranged in different receiving grooves 12. The volumes of the plurality of receiving grooves 12 are different.

[0029] It can be understood that by setting a bracket 41 for placing the chipset 20, and then by setting a plurality of longitudinal partitions 30 to divide the mounting groove 11 of the bracket 41 into a plurality of independent accommodating grooves 12, a plurality of chipsets 20 with different wavelengths can be set in the bracket 41 in different accommodating grooves 12, and controlled separately, so that one lamp bead can realize the function of providing different wavelengths, so that when used as a plant light source, the user only needs to buy one lamp bead, which greatly improves the versatility of the lamp bead, and there is no need to customize different lamp beads and lamps according to different plants, and the customized lamp beads and lamps require additional design costs, which reduces the use cost in disguise. In addition, by setting a plurality of accommodating grooves 12 of different volumes, the number of chips in the chipset 20 in the accommodating grooves 12 of different volumes is different, and the intensity ratio between lights of different wavelengths can be further adjusted, and the emphasis ratio between different wavelengths required by different plants is the same. Such a design enables the lamp bead to adapt to the growth needs of different plants, further improving the versatility of the lamp bead. Therefore, the utility model solves the problem of the lack of a plant lighting lamp bead with strong versatility and low cost in the prior art.

[0030] It should be noted that the absorption rate of chlorophyll for red light and some infrared light with a wavelength of 610nm-720nm is relatively low, but it has a significant effect on photosynthesis and photoperiod effect. This is particularly important for the flowering and fruiting of plants. Red light is a necessary light quality for the normal growth of crops. The biological demand for red light ranks first among various monochromatic light qualities and it is the most important light quality in artificial light sources. The visible blue light with a wavelength of 400nm-520nm is absorbed by chlorophyll and carotenoids in the largest proportion and has the greatest impact on photosynthesis. Plants mainly use UV in this band for the growth of branches and rhizomes. Blue light is a necessary supplementary light quality for red light for crop cultivation. It is a necessary light quality for the normal growth of crops, and the light intensity biological use is second only to red light. Although the far-red light of 730nm is not very meaningful for photosynthesis, its intensity and its ratio with the red light of 660nm play an important role in the morphological construction of crop height, internode length, etc. In addition, in the light environment required by plants, if there is too much green light, the plants will grow slowly and have poor shapes; if there is too little green light, the leaves in the lower layer of the vegetables will turn yellow prematurely and the leaves will age prematurely, and thus green light is also needed for plant growth. In addition, in the light environment required by plants, if there is too much green light, the plants will grow slowly and have poor shapes; if there is too little green light, the leaves in the lower layer of the vegetables will turn yellow prematurely and the leaves will age prematurely. Therefore, by way of example and not limitation, in some optional embodiments, five accommodating grooves 12 are generally provided, which are used to accommodate a red light chipset, a blue light chipset, a far-red light chipset, a green light chipset and a purple light chipset, respectively, and the volume of the accommodating grooves 12 decreases successively, so that the number of corresponding chips in the accommodating grooves 12 decreases successively.

[0031] Specifically, the shape of the bracket 41 is truncated cone, so that the mounting groove 11 is truncated cone. In specific implementation, by setting the bracket 41 in a truncated cone shape, the interface area of ​​the bottom end of the bracket 41 gradually increases to the other end, so that the light emitted by the chip arranged in the bracket 41 is diffused outward along the inner wall of the mounting groove 11. Since the inner wall of the mounting groove 11 is inclined, the light dispersion angle is larger and the illumination area is larger.

[0032] Furthermore, the plurality of longitudinal partitions 30 all pass through the axis of the truncated cone-shaped bracket 41, so that the receiving groove 12 is fan-shaped. The installation groove 11 is divided by the plurality of longitudinal partitions 30 to form a plurality of fan-shaped receiving grooves 12. The fan-shaped receiving grooves 12 are arranged so that it is easy to calculate and adjust the area ratio of each receiving groove 12, which is convenient for processing, and ensures that the light emission angle emitted from each fan-shaped area is large enough, thereby ensuring that the illumination area is large enough.

[0033] In addition, a transverse partition 40 is provided in the mounting groove 11, and the transverse partition 40 divides the receiving groove 12 into a bottom groove 121 and a top groove 122. The chip set 20 is arranged in the top groove 122. The bottom groove 121 is used to accommodate the anode pin of the chip, and the top groove 122 is used to accommodate the cathode pin of the chip. By providing the transverse partition 40, the receiving groove 12 is divided into the top groove 122 and the bottom groove 121, and the cathode pin and the anode pin are respectively accommodated in the top groove 122 and the bottom groove 121, thereby ensuring that the two different electrodes are isolated from each other and ensuring safety.

[0034] By way of example and not limitation, an annular partition 50 is further provided in the mounting groove 11, and the annular partition 50 is used to isolate the longitudinal partition 30 from the inner wall of the mounting groove 11, so that a cathode groove 13 is formed between the inner wall of the mounting groove 11 and the annular partition 50, and a first metal pad 60 is provided in the cathode groove 13, and the cathode pins of the chip are all connected to the first metal pad 60 through the receiving groove 12. By providing the annular partition 50, the cathode groove 13 is formed, and the first metal pad 60 is provided in the cathode groove 13, so that the cathode pins of each chip are all connected to the first metal pad 60, and there is no need to provide metal pads separately, thereby reducing costs. In addition, by providing the cathode groove 13 outside the receiving groove 12, the cathode pins of each chip are easily connected to the first metal pad 60, thereby reducing the difficulty of wiring.

[0035] Specifically, the bottom groove 121 is provided with a second metal pad 70, and the anode pins of the multiple chips are respectively connected to the multiple second metal pads 70 through the transverse partition 40. In the specific implementation, in order to control the chip groups 20 of different wavelengths respectively and achieve different lighting effects, it is necessary to set multiple second metal pads 70 to be connected to different chip groups 20 respectively, so that the intensity ratio between the light of different wavelengths of the lamp bead can be adjusted, and the type of light irradiated in different time periods can be adjusted according to the growth of the plant, which further improves the versatility of the lamp bead.

[0036] See also Figure 4 , shown is a mixed light plant lighting lamp bead in the second embodiment of the utility model. The second embodiment is basically the same as the first embodiment in structure, except that a coaxially arranged annular partition 80 is provided in the installation groove 11, and the two sides of the longitudinal partition 30 are respectively connected to the inner wall of the installation groove 11 and the outer wall of the annular partition 80, so that a plurality of arc-shaped receiving grooves 12 are formed between the installation groove 11 and the annular partition 80, and a circular receiving groove 12 is formed inside the annular partition 80. This arrangement makes it possible to eliminate the narrow corner space in the receiving groove 12, thereby increasing the available space in the receiving groove 12, thereby making the installation space of the chipset 20 larger, so that more chips can be arranged.

[0037] Specifically, the circular receiving groove 12 has the largest volume. In addition, the top of the side wall of the installation groove 11 is recessed inward to form a groove. The arc-shaped receiving groove 12 with the smallest volume is connected to the groove to enclose and form a common cathode groove 90. A third metal pad 100 is provided in the common cathode groove 90. The cathode pins of the chip are all connected to the third metal pad 100 through the receiving groove 12. By providing the common cathode groove 90 and the third metal pad 100 in the common cathode groove 90, the cathode pins of each chip are all connected to the third metal pad 100, and there is no need to provide metal pads separately, which reduces the cost. In addition, by providing the common cathode groove 90 outside the receiving groove 12, the cathode pins of each chip are easily connected to the third metal pad 100, which reduces the wiring difficulty. In addition, in order to ensure that the volume of each accommodating groove 12 is larger, the volume of the circular accommodating groove 12 is set to the largest, so that the circular accommodating groove 12 is closer to the common cathode groove 90, thereby making the arc-shaped accommodating groove 12 with the smallest volume smaller, thereby avoiding wasting more space for the chipset 20 in the circular accommodating groove 12 to contact the common cathode groove 90.

[0038] In summary, the mixed light plant lighting lamp bead in the above embodiment of the utility model is used to place the chipset 20 by setting a bracket 41, and then the mounting groove 11 of the bracket 41 is divided into multiple independent accommodating grooves 12 by setting multiple longitudinal partitions 30, so that multiple chipsets 20 with different wavelengths can be set in the bracket 41 in different accommodating grooves 12, and are controlled separately, so that one lamp bead can realize the function of providing different wavelengths, so that when used as a plant light source, the user only needs to buy one lamp bead, which greatly improves the versatility of the lamp bead, and there is no need to customize different lamp beads and lamps according to different plants, and customized lamp beads and lamps require additional design costs, which reduces the use cost in disguise. In addition, by setting multiple accommodating grooves 12 of different volumes, the number of chips in the chipset 20 in the accommodating grooves 12 of different volumes is different, and the intensity ratio between lights of different wavelengths can be further adjusted, and the emphasis ratio between different wavelengths required by different plants is the same. Such a design enables the lamp bead to adapt to the growth needs of different plants, further improving the versatility of the lamp bead. Therefore, the utility model solves the problem in the prior art of lacking a plant lighting lamp bead with strong versatility and low cost.

[0039] In addition, the utility model also provides a lamp, which includes the above-mentioned mixed light plant lighting lamp beads and a lampshade arranged outside the lamp beads.
