LED Lights Simulate Moonlight to Promote Coral Growth

图片
In front of LED coral lamps, people tried to simulate moonlight with low-power incandescent lamps, even if they did not simulate fluorescent lamps with photocatalytic materials. Hydroponic vegetable light environment is one of the important physical environmental factors indispensable for plant growth and development. Controlling plant morphogenesis through light quality regulation is an important technology in the field of facility cultivation; plant growth lamps are more environmentally friendly and energy-saving, LED plants Lights provide photosynthesis to plants, promote plant growth, reduce the time spent on plant flowering, and increase production! In modern construction, it is an indispensable product for crops. The fleshy bulb has a wide range of wavelengths, which coincides with the spectral range of plant photosynthetic and photomorphogenesis; the spectral wave width is half-width narrow, and pure monochromatic light and composite spectrum can be obtained as needed; the light...

LED Plant Growth Lamp Common Problem Solving

Check if the power supply is working properly and the command light is on. If not, please check if the power supply is connected correctly. Check that the power cord of the lamp is well connected to the positive and negative electrodes of the power supply and that there is any reversal. If the above problem exists, please connect it correctly. 2, LED plant growth lamp beads on the voltage requirements: The nominal 3V LED lamp beads, in fact, different colors have different current requirements, yellow requires the least current, followed by red, green, white and blue. If the current is too large, the wick will be burnt. With a 2.4V rechargeable battery, yellow is easy to burn because even if the voltage is low, the current is too large and it will burn at will. A fleshy bulb with a specific wavelength of LED can affect the flowering time, quality and duration of the flowering of the plant. LEDs of certain wavelengths can increase the number of flower buds and flowering of pla...

How LED Plant Grow Lamp Effects Various Wavelengths of Light on Plants

图片
Effects of light of various wavelengths on plants Visible light wavelength (4*10-7m----7*10-7m) Light color --------- wavelength λ (nm) --------- represents the wavelength Red-----780~630----------700 Orange--630~600----------620 Yellow--600-570----------580 Green--570~500----------550 Qing---400~470----------500 Blue---470~420----------470 Purple--420~380----------420 In order to study the color properties of light, the visible spectrum is enclosed into a circle and divided into nine regions, called color rings. The number on the color ring indicates the wavelength of the corresponding color light, the unit is nanometer, and the color in the fan shape of any two opposite positions on the color ring is called complementary color. For example, the complementary color of blue (435~480nm) is yellow (580~595nm). It has been found through research that the color light also has the following characteristics: (1) The complementary colors are mixed in a certain ratio to obtain ...

High-efficiency Soilless Culture Technique for Aromatic Vegetable Basil

图片
Basil, alias orchid, hairy basil, sweet basil, nine-story tower, etc., is an annual herb of the family Corydalis. Hydroponic plants should be supplied with liquid during the cultivation process to ensure adequate nutrient supply. The liquid supply time is generally selected during the day and no liquid supply or less liquid supply at night. The number of liquid supply on sunny days is more, and there is less liquid supply in rainy days; when the temperature is high, the light is stronger, and vice versa. Usually, the liquid is supplied 2-4 times a day, and it can be grasped for 30 minutes each time. This can be adjusted at the right time with the time controller. Hydroponic plants are exemplified by pipelined hydroponic vegetable production equipment. Production management is mainly to adjust the time of supply of nutrient solution and the number of liquid supply. The liquid supply time and the number of liquid supply times of the nutrient solution are mainly determined according to th...

What is The Role of Plant Lights in Affecting The Plant Growth Cycle?

图片
In traditional agricultural production, the use of ordinary electric light sources to supplement light and the application of different covering materials and other agricultural technical measures, such as the use of monochromatic fluorescent lamps or colored plastic films, to change the light environment to regulate the growth and development of plants in the facility cultivation environment. Led plant lights use different measures to avoid different degrees of problems, such as the lack of analysis of specific spectral components leading to impure light quality, inconsistent light intensity, close to or even below the plant's light compensation point, The illumination source has low energy efficiency. A large number of application studies of LEDs in plant facility cultivation environments have shown that LEDs can solve these problems and are particularly suitable for use in artificial light-controlled plant facility cultivation environments. Plants rely on the energy of ligh...

Noise Countermeasures for LED Bulbs Using Medium and High Voltage Ceramic Capacitors

图片
Recently, in addition to the requirements of small and thin, energy-saving, and low-noise, electronic equipment is expected to meet the ecological needs of the global warming. Under such market demand, the LED bulbs that have been popular since 2009 have become small and thin, and have achieved high eco-friendship due to their long service life. The electronic components mounted on them are also required to be small and thin. It has a long service life. LED bulbs are equipped with a small power supply with a power of about 10W, mainly using electrolytic capacitors and film capacitors to achieve a smooth function, but the use of small and longer-life ceramic capacitors is also increasing. Ceramic capacitors with higher electrostatic capacity than conventional ceramic materials, this paper will introduce its characteristics, and introduce the recommended circuit for power supply of other electronic devices based on LED bulbs. New material ceramic capacitor performance The proper...
