Induction Function Of Solar Garden Lights

-

 In life, we often come into contact with many kinds of sensing functions. There are voice-activated induction, hand-scan induction (commonly used at home), infrared induction, radar microwave induction. The induction of solar garden lights generally uses infrared induction and microwave radar induction.

The full name of infrared sensor is called heat release electric infrared sensor switch. Any object in nature, as long as the temperature is higher than absolute zero (-273°C), always emits infrared radiation continuously. The higher the temperature of the object, the smaller the peak wavelength of infrared radiation it emits, and the greater the energy of infrared radiation. . When a person enters the sensing range, the pyroelectric infrared sensor detects the change of the infrared spectrum of the human body, and the load is automatically turned on (the load here refers to the luminous source), and the sensing distance is about 7 to 9 meters. If the person does not leave the sensing range, it will continue to conduct; after the person leaves, the load will be automatically turned off after a delay.

The microwave radar induction, also known as the microwave induction switch, is based on the Doppler effect and adopts the most advanced planar antenna, which can effectively suppress the interference of high-order harmonics and other clutter, has high sensitivity, strong reliability, and has a long sensing distance. Up to 8 to 12 meters.

From the above description, it can be seen that each has its own advantages. The infrared sensing distance is shorter, while the microwave sensing distance is longer, and the sensitivity is relatively high, and its cost is also more expensive.

It should be noted that the sensitivity of microwave induction is too high, and misjudgment may occur during induction. For example, there is a tree next to the lamp that shakes very much, and the solar garden light may also sense it (as long as there is an object moving, it will A wavelength will be generated, microwave induction will detect this wavelength, and if it is within the wavelength range, it will be sensed), which is a normal phenomenon of microwave induction. Therefore, the requirements of microwave induction are very high, and the sensitivity should not be adjusted too high. When we choose, we can choose suitable products according to the environment of use and installation height. Because the solar garden light is installed outdoors, we try to set the induction function in the second half of the night when setting the lighting mode of the solar garden light, which not only saves energy consumption but also prolongs the lighting time

DO SOLAR LIGHTS WORK IN LESS THAN PERFECT SUNLIGHT?

-
You may be able to count on your mailman in rain, snow, sleet, or shine, but what about your outdoor solar lights? One concern for many solar light owners is what happens to them when the weather is not ideal, be it wintry, rainy, or extremely hot and cold. Since the batteries in solar lighting are charged by daylight, these are understandable worries. Depending on what climate you live in, you may be wondering about how your solar lights will perform in different conditions. Here we will answer a few of the top questions often asked about how solar lights work in the winter and in other situations so that you can be sure to prepare well and purchase accordingly. DO Solar Light For Outside  NEED DIRECT SUNLIGHT TO CHARGE? Generally speaking, outdoor solar lights charge up by receiving direct sunlight. So, the more sunlight received during the day will directly impact how long the light will stay illuminated at night. On average, a fully charged solar light yard  from eigh...

Five Causes, Hazards, and Seven Solutions for Murky Pond Water

  Physical Factors Rainfall washes sediment from the surrounding ground and pond embankments into the pond, leading to water turbidity. Newly excavated ponds lack organic matter at the bottom, resulting in nutrient-deficient water that hinders algae growth. Shallow water combined with wind and aerator agitation can easily cause turbidity. Improper installation of  aeration equipment , especially microporous aerators, where the aeration disc is placed too low, stirring up the bottom sediments when the aerator is turned on. This causes the water to become muddy. Shallow water combined with aeration equipment can exacerbate the issue. It's suggested to use a product like  poposoapsolar . Nutrient-deficient water: When algae are scarce, heavy rains can cause a rapid temperature change between the upper and lower water layers, resulting in density currents. These currents stir up bottom sediments, creating muddy water. Biological Factors Overstocking, particularly of bottom-dw...

DL-METHIONINE BENEFITS IN FOOD ADDITIVES: A COMPREHENSIVE OVERVIEW

-
Image
  Introduction: In recent years, the food industry has witnessed a significant shift towards incorporating natural and sustainable ingredients in food products. DL-Methionine, an essential amino acid, has emerged as a promising food additive, offering a wide range of benefits for both manufacturers and consumers. This text aims to provide a comprehensive overview of the advantages of DL-Methionine as a food additive, its diverse applications, and its role in enhancing the nutritional value and quality of various food products. 1. Understanding DL-Methionine:DL-Methionine, chemically known as 2-amino-4-(methylthio) butyric acid, is a sulfur-containing essential amino acid. It cannot be synthesized by the human body, making it indispensable for maintaining various physiological functions. This amino acid exists in two forms: L-Methionine and D-Methionine. DL-Methionine is a racemic mixture of these two forms and is commonly used in food additives due to its stability and cost-effecti...
