LED plant light heat dissipation test, the heat dissipation performance of LED plant light is directly related to its service life and the luminous efficiency of the lamp beads. The aging test method is to make the LED plant light at its maximum temperature within a certain period of time, and its internal structure will not be damaged. And within a certain period of time, the temperature of each part of the LED plant light will not increase with the prolonged high-intensity working time.
The LED plant light has high efficiency and stability. The main influencing factor is the rectification and voltage division capability of the internal power supply. As long as the quality of the power supply is excellent, the LED plant light is generally acceptable within its rated service life. Ensure high efficiency and normal light emission, and the general power supply will be equipped with an over-voltage automatic power-off device, which will not have a serious impact on the lamp beads, but it does not rule out the possibility of LED plant growth lamp chip leaks during the packaging process, so it is necessary Carry out flashing test to ensure stable, normal and efficient work.
Generally speaking, the aging test is to test the endurance of various situations that may be encountered in actual applications. The difference is the testing method and testing process.
The influence of plant lights and natural light time on plant growth, the influence of plant lights and natural light time on plant growth, plant light time is the time when plants receive natural light or artificial LED plant growth light. Both light intensity and light quality have their own changing laws, and the same is true for light time:
(1) Summer time is longer than winter time (2) Day and night equals all year round near the equator (3) Summer days are short and nights are short (4) Winter days are short and nights are long
Long-day plants: refers to plants that require a long light time. Only when the long light time is regularly reached during the photoperiod, the plants will bloom and set fruits, otherwise they will only grow normally and will not form flower buds. This kind of plant is illuminated by light. Lack of time has a great impact on it, and it is also the plants that most need to use LED plant lights to align and fill light.
Common long-day plants are: impatiens, wheat, spinach, radish and so on.
