Made lamp tube
Therefore, its color is purple. There are red and blue lights in fluorescent lamps, plant lamps, LED bulbs, halogen lamps, incandescent bulbs and other bulbs [don't be fooled by plant lamps].
Plants will absorb useful light waves by themselves during photosynthesis. Farmers mainly consider the problems of cost and benefit [research on energy-saving mode of chrysanthemum lighting]. ◎ If LED bulbs [LED plant lamps imported from Japan] are used, it will save electricity (only 1.6W).
Can achieve the same effect.
But it's too expensive (price 7
980 yen)
No farmer can use it at present.
Unless the electricity bill rises sharply.
The day will come when the price of LED bulbs will be greatly reduced. Nowadays, farmers still use a large number of incandescent bulbs.
That's mainly a matter of cost. ◎ 【 Don't be fooled by plant lights 】: The effect of plant lights on plant photosynthesis.
Unlike ordinary fluorescent lamps with wattage ... reason: plant lamps are made by adding special gases and some heavy metals to ordinary fluorescent tubes.
Absorb and remove light other than red and blue light waves.
The manufactured lamp tube. So: 1) light wave range fluorescent lamps contain all the light waves of plant lamps.
But plants will absorb useful light waves by themselves during photosynthesis. 2) Fluorescent lamps have strong luminosity.
Even in red and blue, the intensity is much stronger (the same 60w lamp).
30 cm down
Fluorescent lamps can reach more than 1500lux.
Plant lights may be less than 1000). 3) Plant lamps are more prone to heat. 4) Plant lamps are more expensive. 5) Note: The spectrum of fluorescent lamps is relatively short.
Less heat energy
Therefore, it is called a cold light tube.
Fewer red lights
So if it is used for optical period control,
The effect is not as good as that of a light bulb.
Because the spectrum of the bulb is on the long wavelength side
Therefore, it is best to use light bulbs for the electro-optical treatment of chrysanthemum and poinsettia. Of course, the best fill light is halogen lamp.
But the price ... ◎ [Japanese introduced LED plant lights]: Although Taiwan Province Province of China has recently developed LED plant lights,
But Japan has always been a pioneer in this technology.
It was not only developed very early,
Commercialization is also fast. A few days ago, Japanese manufacturers launched a new LED light product "My Factory".
Belonging to the LED illuminating lamp for cultivating plants.
Can be used in home potted plants, indoor plant cultivation, greenhouses and other application environments.
In view of the lack of light
Or plants that need additional light sources at night. This product has 2 sets of LED lighting modules.
A module consists of 10 red LEDs and 2 blue LEDs.
The light it emits is harmless to human body.
Can help plants to carry out photosynthesis. The manufacturer pointed out
Although harmless to the human body
But the distance between the lamp and the plant
Not less than10cm.
The suitable distance is 10 cm to 40 cm.
To prevent plants from being burned. Because the product has built-in automatic timing switch
Users can easily set the time when plants need to be irradiated.
Power consumption is quite low.
Only1.6w.
The price is 7 pounds.
980 yen.
