[0001] The utility model relates to the technical field of lawn maintenance, in particular to a telescopic plant supplementary lighting device. Background Art

[0002] With the continuous development of society, people's material and cultural life is becoming more and more rich. Some competitive sports, such as football, are becoming more and more popular among people. Professional football fields, in addition to meeting football matches, also hold some activities such as concerts, exhibitions and other sports events. Therefore, it is necessary to maintain the lawn in a timely manner. At night, the maintenance of the lawn is usually carried out by using supplementary lighting lamps to promote plant growth.

[0003] The current supplementary lighting lamp is an artificial light source used to meet the lighting conditions required for the photosynthesis of green plants on the lawn. Under the condition of lack of sunlight, this kind of lamp can act as sunlight, enabling the lawn to grow and develop better. Most of the existing supplementary lighting devices adopt a fixed structure, and when the equipment is not working, it occupies a large area and is not convenient to move, which causes great trouble for storage and use.

[0048] In this embodiment, as Figure 3As shown, the light-emitting unit 12 uses LED lamp beads, and the LED lamp beads have the following advantages: Some of the main advantages of LED lamp beads are as follows: First, LED lamp beads are highly energy-efficient. The luminous efficiency of LED lamp beads is very high, and the electric energy consumed under the same brightness is much less than that of traditional lighting equipment. This helps to reduce energy consumption, reduce electricity bills, and at the same time helps to relieve the pressure on the power supply. Second, LED lamp beads have a very long service life. The service life of LED lamp beads is usually much longer than that of traditional lighting equipment, and can be up to tens of thousands of hours or even longer. This means that they can be continuously used for many years, reducing the frequency of lamp replacement and maintenance costs. At the same time, LED lamp beads are also more environmentally friendly. LED lamp beads do not produce harmful substances such as heavy metals like mercury during production and use, so they are environmentally friendly. In addition, due to their long life and high efficiency, the generation of waste is reduced, further reducing the negative impact on the environment. Also, LED lamp beads come in a variety of colors. LED lamp beads can produce a variety of colors, from warm white to bright red, blue, etc., providing more possibilities for lighting design. Even according to the light color preferences of different plants, LED lamp beads of corresponding colors can be selected. For example, for heliophytes such as sunflowers, tobacco, and cotton, their leaves contain more chlorophyll a, so they are particularly good at capturing red and orange light in direct sunlight. These plants grow better in sunny places, and their leaves are wide and light in color to absorb more sunlight. For example, for sciophytes such as ginseng, ginger, and pepper, their leaves are rich in chlorophyll b, so they prefer to grow in shaded environments, and the purple and blue light in diffused light is what they prefer. At the same time, LED lamp beads also have the advantage of quick start. LED lamp beads can reach full brightness immediately without a preheating time, which is very useful in situations that require quick response. In summary, LED lamp beads have the advantages of high energy efficiency, long life, environmental friendliness, rich colors, and quick start, and are very suitable as the light-emitting unit 12 of the telescopic plant supplementary lighting device.
