This project proposes a light control for greenhouse planting chrysanthemums in order to study the use of แสงจา more time led compared with light from a fluorescent lamp On growth of chrysanthemum with brightness between 60 100 Deluxe and deluxeThe experimental results using led to the light 100 Deluxe and deluxe 60, growth rate of chrysanthemum 4.4 cm and 3.8 cm per week. And the results from using the fluorescent lamp to light for the greenhouse 100 Deluxe and deluxe 60 new growth of chrysanthemum was a 3.8 cm. And the 3.2 cm per week. As a result of the comparison of energy consumption in experiment period 4 week. Rate of energy of the LED is 4 units, while light from the fluorescent lamp used 18.1 units. The measurement of the light in the house between the design in the program the diaphragm lux. And from the measurement of the light. In the house to light 100 Deluxe and deluxe 60 using led the accuracy rate is 84.72% 91.76% for greenhouse and brightness 100 lux. 60 Deluxe and using fluorescent tube has accuracy and 93.87% 95.44%.
