Main Factors Affecting the Thermal Resistance of LED Light Source Components

1, the structure and raw materials of the LED chip is also one of the factors affecting the thermal resistance of the LED, reducing the thermal resistance of the LED itself is the primary condition. 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 plants; LEDs of certain wavelengths can reduce the flowering reaction, regulate the length of peduncle and flowering period, and facilitate the production and market of cut flowers. It can be seen that the flowering and subsequent growth of the plants can be regulated by LED regulation. Heat sink materials with different thermal conductivity (such as copper and aluminum) also have a great influence on the thermal resistance of LEDs. Therefore, selecting a suitable heat sink material is also one of the methods to reduce the thermal resistance of LED devices.


2. Even if the same heat sink material is used, it is directly related to the size of the heat sink area. The secondary heat dissipation design is reasonable, the area is large, and the thermal resistance is correspondingly reduced. This plays an important role in extending the luminous efficiency and life of the LED.
3. The thermal paste of the LED chip is still directly connected to the metal. Different materials, including thermal paste and metal, can affect the heat resistance of the LED. The thermal resistance between the LED and the secondary cooler loading interface should be as low as possible.
4, the operating temperature of the LED component is too high, which will also affect the thermal resistance of the LED component and reduce the ambient temperature. 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 of a specific wavelength can be concentrated to illuminate the crop evenly; The flowering and fruiting of the crop can be adjusted, and the plant height and the nutrient composition of the plant can be controlled; the system has less heat and takes up less space, and can be used for the multi-layer cultivation stereoscopic combination system, realizing low heat load and miniaturization of the production space.
5, the selection of cathode materials and control of the rated import power and other technical details, in order to improve the LED luminous efficiency and extend the life of the LED premise, to deal with the heat dissipation problem of LED.

Introduction of Automatic Planting Production System For Hydroponic Plant Leafy Vegetables

图片
Hydroponics refers to a soilless cultivation method in which part of the roots of plants grow in a nutrient solution, and the other part is exposed to moist air, and then hydroponic cultivation is carried out with nutrient solution and fill light. Next, we will explain how hydroponics is automated and planted. What are the characteristics of this system? Introduction of characteristics, processes, trends, production, types, etc. of hydroponic plant and vegetable automated production systems 1. Characteristics of hydroponic plant and vegetable production Since leafy vegetables mostly eat the stems and leaves of plants, some leafy vegetables are mainly raw food, so the safety and hygiene requirements for products are high. Hydroponic leafy vegetables are more clean, fresh, safe, and of higher quality than traditional soil cultured leafy vegetables. Therefore, the application of hydroponic culture in leafy production is becoming more and more popular. The leaf culture adopts

on VANQ and South China Agricultural Universi Shenzhen VANQ Technology Co., Ltd.  signed a school-enterprise cooperation agreement with  South China Agricultural University In order to meet the needs of business development in the field of agricultural applications, as well as product development and testing, and to take advantage of both the school and the company. On September 14, 2017, three people from VANQ went to the Horticultural College of South China Agricultural University to hold a school-enterprise cooperation signing ceremony. The specific cooperation methods were clarified, and cooperation matters such as technical guidance, base construction, and talent transportation were discussed. The guests attending the signing ceremony included Mr. Chen Riyuan, Professor of South China Agricultural University, Mr. Jiao Haitao, General Manager of Shenzhen VANQ Technology Co., Ltd., and Mr. Xie Hui, Manager of R&D Department.

Natural Light-Indoor LED Plant Growth Light

hi, I have more 50-watt girl lights, which I got from my husband. In this project, there are some differences, they actually have a built-in timer, or my previous VANQ LED plant grow light has a mechanical timer there, so this is a good thing, so let’s open the package and see us What do you get like you have three bulbs, we can use a timer to destroy the switch, it looks like you can perform 12 12 hours, maybe 9 hours 3 hours, along this line, we have bulbs here, they are LED lights , They are not pink, like everyone else, I think these are more colors of the sun, which seems strange to me, so all the LEDs are many, so they are very sturdy. I think you can remove the bottom thing, let's see if we can assemble something, and then let me remove these things, we can start to assemble the thing and see its appearance, so this is the light bulb, they look very cool, just like a normal light bulb, you can also screw it into the accessory and continue the operation. I don't know wh
