About the Heat Dissipation Method of LED Plant Lights

图片
As the name implies, the fan generated by air convection forces the cooling fan, and the heat-dissipating lamp body outside the air source is forced to cool by the fan, which can be very effective for cooling and heating, computer and automobile fan forced cooling. The led lamp is an electroluminescent semiconductor material chip, which is cured with silver or white glue to the bracket, and then connected to the chip and the circuit board with silver wire or gold wire, and sealed with epoxy resin to protect the inner core wire. Function, and finally install the outer casing, so the LED lamp has good seismic performance. The design of the LED lamp should determine the number of fans according to the actual situation. As long as there is good heat dissipation, the fewer the number of fans, the better, because more and more fans, the cost and power consumption of the entire luminaire will also increase. Electromagnetic jet cooling: Electromagnetic radiation jet fan blades are not us

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 sa

1, chip: mainly reflected in solder pad contamination, chip damage, chip size, chip tilt and so on. Preparatory measures: Strictly control feed testing and identify issues that require supplier improvement. 2, bracket: mainly reflected in the bracket size and C size deviation is too large, the bracket color rust, bracket deformation and so on. In the absence of daylight, led lamps can act as daylight, allowing plants to grow normally or better. This kind of lamp has strong roots, encourages, regulates flowering and flower color, promotes fruit ripening, coloring, and enhances the taste and quality!

Intelligent Automatic Hydroponic Green Vegetable Project Accelerated Construction

Abstract : In the past few days, the Jiahe intelligent automatic hydroponic green vegetable project in Hanjiang has been established, and various machines have been shuttled. The construction unit is grabbing the sunny weather and tightening the land leveling operation to ensure that the project will be promoted according to the node. 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 the cultivation form, the growth state of the vegetables, and the environmental conditions. The establishment of this goal is the implementation of the party's 19th National Energy in Hanjiang District, promoting high-yield and high-efficiency. In the past few days, the Jiahe intelligent automatic hydroponic green vegetable p

Overall Growth Balance of LED Plant Assisted Lamps

The following is a list of wavelengths for different color LEDs: Royal Blue: 445 nm 440 nm~460 nm Blue: 460~490 nm 470 nm Blue: Cyan 490~505 nm Green: 520~550 nm 530 nm Green Red: Red 627 nm 620~645 Orange: 617 nm 613~620 nm Amber: Amber LED Plant Light 590 nm 585~597 nm{+*/) On this table, it is not difficult to find blue (470 Nm) and red (627 Nm) LEDs, only plant light, so LED lights, the ideal choice is to use a combination of two colors. 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

LED Plant Growth Light: Beautiful Without Sunlight

The LED plant growth lamp is a lamp that uses LEDs (light-emitting diodes) as a light source, LED plant growth lamps instead of sunlight for plant growth and photosynthesis. Through the plant form of light to regulate the flowering of plants, when the fruit can be used, the water is more and the nutritional value is higher. The greenhouse technology engineer of Qinlong Modern Ecological Innovation Innovation Agricultural Park said to Yan Liang that the LED plant growth lamp is a facility. An important technology in the field of vegetable cultivation. He explained that LED plant lights have no sunlight and look very beautiful. Vegetables can only absorb orange light and blue-violet light energy under sunlight, and the utilization rate is low, which affects the natural environment. LED plant growth lamps can adjust the spectrum according to the variety of vegetables and the needs of the growth stage. The stems and leaves of the plant are blue, and the flowers and fruits are red. It takes
