Description

Environment-friendly energy-saving color-leaf street lamp system

Technical Field

The utility model belongs to the technical field of the street lamp illumination, concretely relates to utilize leaf reflection of light to illuminate various leaf street lamp system of environmental protection and energy saving of surrounding environment.

Background

In cities, street/roadside, there are some street lights and trees, some often interwoven with trees. The inventors noted that: dense green leaves on the trees can absorb/shield street lamp light, so that the environments at night such as the street side/roadside are dim. The information is consulted to know that: the green leaf has a reflectance of visible light of less than 20%. In other words, the green leaves absorb street light with a loss of 80%. Therefore, municipal departments have to increase the power of the street lamps so that the road surface and other night environments are bright.

In order to beautify nights of cities, a brightening method that a high-power color spotlight projects color lights to trees is adopted in some cities. The green leaves have the reflectivity of less than 20 percent to visible light, so the method has high investment, large power consumption and monotonous color, is not suitable for being used as a street lamp, is only suitable for being used in holiday periods and is not suitable for being used all the year round.

The urban green belt is enjoyed by people, has only ornamental value and does not need to seek high yield and high harvest like crops (such as vegetables/grains). It should not be watered, fertilized, and trimmed as often as it is to treat a crop without the need for it to thrive. However, plants in greenbelts are intended to grow naturally, and excessively fast growth (i.e., unnecessary growth) requires extensive watering, fertilizing, and manual pruning. In another view, the inventor believes that the plants in the urban green belts, which only have ornamental value, should be shaped after growing to a certain extent, should stop growing, and continue growing is redundant, unnecessary, and causes much trouble and waste.

Plant transpiration refers to the process by which water on the surface of a plant (primarily the leaves) is released into the air in the form of water vapor. The transpiration process is as follows: water in soil → root hair → root canal → stem canal → leaf canal → stomata → atmosphere. This process requires energy supplied by solar irradiation.

Plant transpiration occurs in three places:

1. air holes: the air holes are distributed on the leaves and the green stems, water is evaporated from plant cells, water vapor is diffused to the outside through the air holes, and about 90 percent of water is dissipated through the path;

2. horny layer: water evaporates at the cell wall of the epidermal cell and passes through the stratum corneum covering the leaves and green stem, and about 10% of the water is lost through this pathway;

3. skin hole: the water vapor is dissipated through the bark holes on the wood stem, and the dissipation rate of the path is small.

External factors affecting plant transpiration:

1. sunlight: the opening of air holes is promoted by the irradiation of sunlight, so that the transpiration is enhanced;

2. moisture content: the soil has enough moisture to facilitate the opening of air holes;

3. temperature: the vent opening generally increases with increasing temperature;

4. wind: breeze is favorable for transpiration;

5、CO₂concentration: CO 2₂Too low concentration can promote the open of pores and enhance transpiration.

The transpiration rate of several plants in the daytime is 15-250 g/m²At night, the concentration is 1-20 g/m²H is used as the reference value. The transpiration coefficient, also known as water demand, refers to the grams of water consumed by a plant per 1g of dry matter produced. The transpiration coefficient of most plants is 125-1000. Woody plants have a relatively low transpiration coefficient, such as about 40 for pine; the herbaceous plant has a high transpiration coefficient, the corn is 370, and the water lost by the corn in the whole transpiration is 400 and 500 kg, which is really too much. Therefore, the plant transpiration acts like a water pump, and nutrients such as water, fertilizers and the like in the soil can be pumped out.

In other words, the present inventors consider that the negative effect of plant transpiration is: and unnecessary huge waste of water, fertilizer, manpower and the like is caused to the urban green belt. In other words, only the urban green belts with ornamental value cause unnecessary huge waste of water, fertilizer, manpower and the like due to transpiration.
