Description

Technical Field

[0001] This invention relates to the field of insecticidal devices, and more particularly to an insecticidal lamp that can promote plant growth. Background Technology

[0002] In addition to chemical control, physical control is also an effective means of pest control in agriculture and forestry. Common physical pest control methods are divided into two categories: one is to utilize the color attraction or odor attraction of agricultural and forestry pests, by coating colored cardboard or wood with glue or machine oil to kill some small pests, commonly known as 'insect-killing color boards'; the other is to utilize the phototaxis of agricultural and forestry pests, by using light to attract and kill pests, called 'insect-killing lamps', whose pest-killing effect is far superior to insect-killing color boards. In the past thirty years, electric light sources have been used to attract pests, and later, high-voltage grids constructed with electronic components were used to kill pests. In the current technology, the mainstream insect-killing lamps and their complete machines are characterized by black light sources and high-voltage grids as core technologies. A black light lamp is a low-pressure fluorescent mercury lamp that emits a main wavelength of 360-380nm. The main radiation energy of this gas discharge lamp is concentrated outside the low end of the visible light range, hence the name "black light lamp". In fact, even if its glass casing is transparent, the human eye can still see that it emits purple or violet-blue light. Besides black light lamps, new types of lamps for attracting pests have also emerged in the industry, such as dual-wave lamps and frequency-vibration lamps.

[0003] Existing LED insect-attracting lamps mostly use monochromatic LEDs with a narrow spectrum, which can only attract and kill a small number of pests sensitive to that spectrum, resulting in low efficiency. Another type of LED insect-attracting lamp can automatically cycle through different light sources, but this type of lamp cannot dynamically select the light source based on the actual pest infestation, nor can it be remotely controlled. Therefore, existing technologies have shortcomings and need to be improved.

[0004] A utility model patent with patent number CN206386715U, entitled "An LED Full-Spectrum Insecticidal, Sterilizing, and Modular Plant Growth Promoting Lamp," discloses a lamp with full-spectrum properties. It includes LED beads that not only provide light across all wavelengths promoting plant growth but also LED beads for attracting insects, sterilizing, and generating heat. The ultraviolet light, in addition to attracting insects, also kills small flying insects such as mosquitoes. It can meet the needs of various plant production, including vegetables, fruits, and field crops. While promoting plant growth, it can also significantly reduce the stimulation of plants' absorption of potassium and nitrogen fertilizers. The lamp's light output angle is adjustable to meet the lighting needs of different heights and areas. For example, a narrow beam is used to illuminate low-growing plants such as millet, while a wide beam is used to illuminate tall fruit trees. This solution integrates plant supplemental lighting, insect attraction, sterilization, and heating functions, achieving a high degree of integration. Furthermore, it incorporates wireless control, reducing the workload of management personnel and effectively saving production costs. However, this lamp uses a sliding lens sleeve to move the focusing lens to adjust the light convergence and divergence, thereby adjusting the light range and intensity, which makes the structure relatively complex; moreover, the adjustment of the light range and intensity is mainly to meet the needs of plant growth, and it is difficult to take into account the insecticidal effect.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "at least" means one or more, unless otherwise explicitly specified.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components.

[0034] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0035] like Figures 1-3As shown, an insecticidal lamp that promotes plant growth includes: a lampshade 1, a power supply box 3, a light source, an electric grid 4, and a lamp holder 8; characterized in that it further includes a first temperature sensor for detecting the temperature around the electric grid; the light source is an LED full-spectrum light source 5, which is composed of a plurality of LED beads with wavelengths of 310-360nm, 400-520nm, and 660-940nm; a controller connected to the first temperature sensor and the LED full-spectrum light source is provided in the power supply box 3, and the controller controls the shutdown of a plurality of the LED beads according to the temperature signal fed back by the first temperature sensor.

[0036] In this embodiment, the LED full-spectrum light source 5 is preferably composed of several LED beads with dominant wavelengths of 310nm, 360nm, 400nm, 460nm, 520nm, 660nm, 730nm, and 940nm. This achieves optimal full-spectrum simulation, and when the LED beads are subsequently turned off, several wavelengths can be selectively disabled without affecting the insecticidal and plant growth-promoting effects.

[0037] In this embodiment, LED beads with the same main wavelength are connected in series, and LED beads with different main wavelengths are connected in parallel. When the controller controls the shutdown of a number of LED beads according to the temperature signal fed back by the first temperature sensor, LED beads with main wavelengths of 310nm, 460nm and 730nm are shut down first.

[0038] The LED full-spectrum light source 5 is a mixed light source that is infinitely close to the solar spectrum. In this embodiment, full-spectrum LED tubes can be used as the light source. When the controller receives a signal that the temperature of the LED full-spectrum light source is higher than a set value, the controller controls the shutdown of several LED beads. The shutdown order and set value of the LED beads can be set according to the actual situation. For example, the main wavelength LED beads that mosquitoes are less interested in or the LED beads that emit infrared light can be shut down first. The selected set value makes the temperature of the lamp body slightly higher than the ambient temperature. Flying insects not only have a strange fondness for violet light with a wavelength of 365 nanometers, but are also interested in blue light with a wavelength of 400-500 nanometers and red light (infrared light) with a wavelength of 600-900 nanometers. Small flying insects are phototactic and sensitive to temperature. Using a full-spectrum light source with a lamp body that is slightly warmer than the ambient temperature is ideal for making an insect-attracting lamp. In addition, this insecticidal lamp can be used as a plant lamp or for normal lighting and is harmless to humans and livestock.

[0039] In other embodiments, a second temperature sensor for monitoring ambient temperature is also included, the second temperature sensor being connected to the controller. The controller compares and judges the temperature signals fed back by the first temperature sensor and the second temperature sensor, and controls the shutdown of a plurality of the LED light-emitting beads according to the judgment result.

[0040] Furthermore, the second temperature sensor is mounted on the lampshade 1 and / or the lamp holder 8, and the number of the second temperature sensors is one, two, or more. A safety net 6 is provided around the outside of the power grid, and the first temperature sensor is mounted on the safety net 6, and the number of the first temperature sensors is one, two, or more.

[0041] Specifically, the lamp holder 8 is provided with a bracket for fixing the lampshade 1. The light source is located at the bottom of the lampshade 1, the electric grid 4 is located around the outer periphery of the light source, and the safety net 6 is located on the bracket. A collection tray 7, corresponding to the electric grid 4, is detachably provided on the bracket for collecting insects killed by the electric grid 4. A bracket ring is provided at the bottom of the bracket, and the collection tray is mounted on the bracket ring. In this embodiment, the collection tray 7 and the bracket ring are connected by mutually cooperating buckles and slots. The collection tray 7 has a clearance hole for avoiding the lamp holder 8, and the collection tray is located at the bottom of the electric grid, allowing insects killed by the electric grid to fall into the collection tray. After passing through the lamp holder, the collection tray connects to the bracket ring. The cross-sectional area of ​​the lamp holder is smaller than the cross-sectional area of ​​the electric grid, allowing the collection tray to be located at the bottom of the electric grid. The top of the lamp holder 8 is an arc surface extending outwards and downwards from the center, so that if an insect falls onto the lamp holder, it can slide onto the collection tray.

[0042] Drainage holes are provided at the bottom of the insect collection tray 7 to prevent rainwater from accumulating inside the tray when it rains.

[0043] It should also be noted that the power supply box 3 is fixed to the bottom of the lampshade 1. A mounting base for installing the LED full-spectrum light source 5 is provided at the bottom of the power supply box, and the mounting base and the power lead pins of the LED full-spectrum light source are plugged in and engaged. A mounting flange for installing the electric grid 4 is provided on the power supply box 3, and a mounting position is provided on the mounting flange. A conductive mounting rod is provided on the top of the electric grid 4, and a through hole is provided on the conductive mounting rod to mate with the mounting position. The electric grid and the mounting flange are connected by screws. There are two conductive mounting rods, one for the positive terminal and one for the negative terminal. The electric grid surrounds the LED full-spectrum light source 360 ​​degrees, with an operating voltage of 500-5000V and a short-circuit current of less than 5 mA, posing no danger to normal people. It provides 360-degree insecticidal protection with no blind spots and is more powerful. The mounting base is located in the middle of the power supply box, and the mounting flange is located on the outer edge of the power supply box, so that the electric grid is fitted onto the LED full-spectrum light source.

[0044] More specifically, the power supply box 3 is equipped with a power switch 2 for controlling the full-spectrum LED light source and / or the power grid. The power cord 9 connected to the power supply box 3 is introduced from the lamp holder 8 to facilitate powering the entire insecticidal lamp.

[0045] It should also be noted that the safety net 6 is a spiral protective net wound around the support. In this embodiment, the safety net is fixed to the support by an insect-collecting disc installed on the support ring. In other embodiments, the safety net is an elastic spiral net that is tightly fixed to the support. This allows the spiral protective net to be pressed or removed when the power box or power grid inside the safety net needs maintenance.

[0046] Figure 4 The diagram shown illustrates the circuit control principle of the mosquito-killing lamp provided by this invention. The power supply box is connected to the mains power supply via a power cord. A voltage boost circuit is used to increase the mains voltage, enabling the mains power to kill mosquitoes. The lamp is driven to emit light by an LED driver circuit using a full-spectrum LED light source. The voltage boost circuit and LED driver circuit in this embodiment are existing technologies and will not be described in detail here.
