5 aspects to pay attention to about high-quality LED plant lights

2021-08-3119

From what is LED plant light, why choose LED plant light to what is high-quality LED plant light. People never know it until they start to understand it, which shows that LED plant lights are recognized and recognized by people, but if you want to know more about LED plant lights, you can pay attention to the following 5 points.


LED plant light chip quality


High-quality LED chip manufacturing comes at a price. Each diode must be manufactured to accurate specifications to emit the correct wavelength and maintain its integrity over time. "Light-emitting diodes are made of special semiconductor compounds. They are mixed together in different proportions to produce colors of different wavelengths.


One thing to note about the quality of LED plant light chips is that some reputable manufacturers use complex technical processes to ensure that the diodes they produce emit the correct wavelength of light and are highly durable electronic components. However, there are also a large number of cheaply produced LED chips aimed at attracting budget-conscious consumers, who may not be aware of the differences in the quality of LED chips. Inexpensive LED chips may or may not emit the wavelengths required by our plants, and the intensity of the emitted light will change the wavelength and/or decrease soon after use.


In all types of lamps, the amount of light emitted (measured in lumens or PAR photon irradiance) decreases with use. The output attenuation of traditional incandescent bulbs is much faster than that of LED plant lights. LED grow lights can maintain 70% of their initial output for 50,000 hours or more, depending on operating conditions and other factors.


LED plant light wavelength


When buying an LED grow light, the emitted wavelength is very important. We know that plants need or must include the blue and red of the entire PAR spectrum. If manufacturers of LED grow lights claim that they provide a perfect spectrum for your plants, you should still be aware that not all manufacturers of LED grow lights have this ability to achieve a perfect spectrum, and most manufacturers use this as an excuse to sell Own product. The wavelength of the LED plant light needs the full PAR spectrum, and the focus is on the blue and red wavelengths, which can allow plants to thrive during growth and flowering.


LED plant light watt


The light output of LED grow lights is not just a function of watt input. It depends on the quality of its components and the overall design, including the specific LED chips used, chip density, optics used, heat sinks and drivers. As the power increases, the efficiency of the LED will decrease, because the increase in the temperature of the electronic circuit board containing the LED will result in a significant decrease in the efficiency of the LED. In other words, an LED driven at 3 watts emits about three times less light than the same LED driven at 1 watt!


If manufacturers of LED grow lights boast that watts are a measure of their products, then please be skeptical. Before the standard was adopted, we judged how much power we need for LED plant lights based on our planting area and plants, consulted multiple manufacturers for the same power and different price effects, and finally compared and selected the appropriate power.


LED plant light intensity


If you can use a light meter that measures lumens, lux, or PAR, try measuring at different distances from any type of light source. You will soon discover that when you move the meter farther away from the light source, the light intensity drops rapidly.


This relationship between the light intensity (output) and the distance from the light source is well understood as a physical law, and the light intensity of each grow lamp behaves the same.


It is important to understand this when comparing different LED grow lights. When comparing lamps, what you can easily find is that high-quality LED grow lights usually boast how close the plants are to the light source. This is one of the reasons why LED plant lights are changing modern agriculture. Adequate light intensity and light source distance adjustment can meet the needs of plant growth.


When comparing growth lamps, light intensity is one of the most important measurements. More light intensity is only somewhat better. But be aware that too much light intensity will burn the plant tissues, so the light source distance should be adjusted appropriately.


Lumens, PAR and Lux


Lumen is a unit of measurement used to describe the total amount of light in the visible spectrum emitted from a light source. But the most important thing is not how much light the LED plant light can emit-it is important to know how much light will actually reach your plants. Illuminance is a measure of the amount of light reaching a surface, defined as lumens per square meter or lux. Lux is a human eye measurement and is not recommended for plant applications-although a conversion factor can be used to convert it to micromoles.


The key is the difference between the way humans perceive light intensity (in lumens) and the way plants absorb and use light. This difference is why we really have to use different types of meters to measure the light output of LED grow lights. PAR photon irradiance (usually abbreviated as PAR) is the measurement value that provides us with the most useful information for comparing LED grow lights. The recommended measurement unit for PAR is µmol m -2 s -1.


High-quality LED plant growth lights will provide you with information about the light wavelength distribution of light emission, the size of the area to be illuminated, and the available energy for plant horizontal photosynthesis (PAR photon irradiance). The most accurate instrument for measuring light output is a spectroradiometer. Some LED plant lights include a spectrum of the emission wavelength measured by the spectroradiometer in their specifications. The spectrometer is a very expensive instrument and is rarely used by lamp manufacturers who lack understanding of its value by plant biologists.



From the above 5 points of understanding of LED plant lights, I believe it can help you make the right choice when choosing high-quality LED plant lights. LED plant lights can give plants the best light supplement effect, which is important for the development of modern agriculture. Contribution.
