The 6000-hour lumen maintenance rate of this test 3535 white light product is: 99.7%@55°C, 99.0%@85°C, 98.1%@100°C, and the color shift Δu'v' is 0.0010-0.0014, which indicates that the product life can be External publicity is more than 36,000 hours. According to the life estimation method specified by IES TM-21, the estimated life is 499000-129000 hours.
The LM-80 is the IESNA (North American Institute of Lighting Engineering) approved lumen maintenance rate (LED lifetime) standard. The LM-80 test focuses on components of the light source, including LED packages, arrays, and modules, and uses this data to estimate component life. Manufacturers of LED lights, light engines and LED luminaires are required to obtain the ENERGY STAR certification issued by the US Environmental Protection Agency, and the devices used in their products must meet the requirements of the LM-80 standard test.
The test report is excerpted as follows:
Industry control printed circuit boards (PCB)
1. For industrial control, special or general-purpose circuit board, the bottom circuit is completed, and IO is reserved. After buying the industrial control circuit board, the input and output ports reserved on the circuit board are connected to the user's own device, such as motor, solenoid valves, sensors, thus completing the function want to accomplish.
2. The special circuit board is a board specially designed for a certain function, such as the temperature control circuit board. After buying it, the input port is connected to the thermocouple, and the output port is connected with a heating contactor or a solid state relay to control the heating device to complete the temperature control. There are flow control boards, motion control boards, etc.
3. The universal control board, most of which can be programmed, after the user's own secondary development, completes a specific function, and has a wide range of uses. For example, plc is a general industrial control board. After the user writes the program and compiles the input, various functions can be completed. Digital input, analog input port, high-speed counter port, digital output port, analog output port, and some also have communication function.
