The "Past and Present" of LED Plant Lights
Light environment is one of the important physical environmental factors that are indispensable for plant growth and development. Through light quality regulation, controlling plant morphology is an important technology in the field of facility cultivation. In the beginning, plants could only grow in the open air, because of many uncontrollable factors in nature, the quality and yield of crops are full of uncertainty. So there was greenhouse planting. greenhouse planting is
When studying the photosynthesis of plants under solar radiation, the wavelength of the PAR value used by countries all over the world is only described in the range of 400nm-700nm. Many LED plant lights that claim to be full-spectrum have UV and FR partial bands, but they are still Use PPFD to represent the spectral parameters. Because PPFD does not describe the radiation of UV and FR, the number of micromoles less than 400nm and greater than 700nm is not included. The PPFD value of this full-spectrum plant lamp ignores the existing spectral rad

Introduction to LED grow lights
LED plant growth lamp is an artificial light source that uses LED (light emitting diode) as the luminous body to meet the lighting conditions required for plant photosynthesis. Classified by type, it belongs to the third generation of plant supplement light! In an environment lacking daylight, this lamp can act as daylight, enabling plants to grow and develop normally or better. This kind of lamp has strong r
Which plant fill light is better
I think many of my friends have never heard of plant supplementary light. Plant supplementary light uses light to photosynthesize plants according to the law of plant growth. The plant supplementary light simply replaces the sunlight to some extent. Everyone knows that plants need photosynthesis. When they grow, they will supplement the light energy to the greatest extent, and photosynthesize under the action of light. However, in order to improve agricultural efficiency, plant supplementary lights are now used in many cases to replace sunlight a
Principles of LED plant lights and precautions for use
Research on the principle, characteristics and use of LED full-spectrum plant lighting: Light environment is one of the important physical environmental factors indispensable for plant growth and development. Through light quality adjustment, control of plant morphology is an important technology in the field of facility cultivation; plant growth lights are more environmentally friendly and energy-saving, LED plant lights give plants Provide photosynthesis, promote plant growth
How to test the waterproof performance of plant lights?
Plant lights, as the name suggests, are lamps used when plants grow. Plant lights are plant growth lights or seedling supplementary lights to supplement light for plants or completely replace sunlight to achieve the purpose of photosynthesis. However, since most of the application scenarios of plant lights are in the greenhouses for plant cultivation, under normal circumstances, the humidity in the greenhouses is very high, which means that the plant lights may be exposed to water relatively high, so in order to ensure that the plant lights can l
How to control the fill light for plants, duration and distance
In the photosynthesis of plants, sunlight is an indispensable condition, so when the light is insufficient, the plants cannot grow healthily, so many growers will find ways to artificially supplement the plants with light, and the plant supplement light will be born accordingly. . However, if you want to use the plant fill light to have a good effect, in addition to using the appropriate fill light, you must also have the correct method of use, such as the distance between the fill light and the plant, and the use time of the fill light Notice.
What are the application characteristics of LED light pole screens?
LED light pole screens are gradually being understood by people, and the demand on the market is increasing. More use of LED light pole screens to publish information. The main LED light pole screen has the following characteristics: First, high efficiency and energy saving. The LED lamp installed in the LED light pole screen has light unidirectionality and will not produce light diffusion, so as to ensure that the LED light pole screen can maintain a bright and clear picture d
The difference between fluorescent lamps and incandescent lamps
1. Incandescent lamp Incandescent lamp, that is, the commonly used electric bulb, is the electric current passing through the filament to generate heat. When the filament is in the incandescent state, it can emit light. The higher the temperature of the filament, the brighter, hence the name. When an incandescent lamp emits light, a large amount of electrical energy is converted into heat energy, and a very small pa
Which eye protector is fluorescent light or led?
Fluorescent lamp and led which eye protection Various lights are used in modern society, which has caused the problem of light pollution. Specifically, light pollution refers to the fact that the excessively high brightness of lamps or lamps directly enters the field of view. The severity of the glare effect depends on the brightness and size of the light source, the position of the light source in the field of view, the direction of the observer`s line of sight, the level of illumina
LED soft light with power supply classification
LED flexible light strips need to be equipped with different power supplies according to different models. How much do you know about the power supply? Do you know the type of power supply required for LED flexible light strips and their different meanings? I will tell you today Talk about the classification knowledge of LED soft light with power supply. LED flexible light strip power supplies have different classification methods according to different standards. This article
Analysis and maintenance: Turn on the damaged LED light and check it. No water stains are found, indicating that it is not caused by rain. Then the inspection found that the C2 bulge is suspected to be damaged by overvoltage. Since the construction site is a bit far away from the county seat, I decided to repair the damaged LED lights myself. After replacing C2 with the same electrolytic capacitor, check the lamp beads on the lamp board one by one with a 3V dry battery, and fou
I have visited the LED lamp bead manufacturers to realize that it is not easy
Small LED lamp beads, its main components are: bracket, chip, glue, phosphor, wire. It can be said that although the sparrow is small, it has all five internal organs. Pressure welding is a key link in the packaging technology of LED light-emitting diodes, and we will only introduce this link today. The wire connecting the LED lamp bead to the chip and the 2 conductive pins is called a wire. Basically, the wires are made of 0.999 pure gold wire, the diameter is divided into: 0.8mil, 1.0mil. There are also some manufacturers pursuing low prices wi
Fluorescent lamps are also known as fluorescent lamps, so fluorescent lamps are fluorescent lamps. Fluorescent lamps are commonly known as "electric rods", which are slender cylindrical white opaque glass tubes (the white substance in the tube is the fluorescent powder that causes the light, so it is also called fluorescent lamp), and there are two thin legs at each end. Because the light emitted by the sun does not cause the object to change color, it is called a fluorescent lamp. The use is very wide. There are also column type, ring type, U ty
Introduction to incandescent lamps
Introduction to incandescent lamps Incandescent lamp is a kind of heat radiation light source, the energy conversion efficiency is very low, only 2% to 4% of the electric energy is converted into light that the eyes can feel. However, incandescent lamps have the advantages of good color rendering, continuous spectrum, and convenient use, so they are still widely used. Incandescent lamp composition structure
The difference between LED lights and ordinary lights.
one. LED bulb lamp and ordinary incandescent lamp Luminous efficiency The luminous efficiency of the LED is 100 lumens/watt, the light transmittance of the bulb lamp mask is 75%, and the power factor of our company's entire product is above 0.9. In this way, the luminous efficiency of the entire LED lamp is 100*75%*0.9= 67.5 lumens/watt.
