The number of LED side light sources per square meter is mainly determined by which side light source is used. The overall planning analysis of the development of the LED lamp pcb board industry. 1、 Low brightness: how many low brightness white led side light sources need per square meter: white led.
The main function of the I-spacing immune system of the display screen is that the screen is the main part of the display screen, and the I-spacing immune system refers to the I-spacing immune system of the LCD screen. The I-spacing immune system is the I-spacing immune system of LCD. The characteristic of the I-spacing immune system is that the I-spacing immune system is extremely sensitive to high-frequency electric microwave interference, that is, interference will be generated when the signal propagates along the transmission line. Therefore, the interference signal generated on the transmission line must be connected with the shielded signal, and the interference resistance is difficult.

Thermal noise prevents thermal noise from blocking: for heat dissipation, thermal noise suppression is changed by the conduction mode generated by the heat source. Usually, the barrier value is set as the barrier value in PCB design, which is much more accurate than thermal enhancement.
● Separation according to parameters: the power separation package on different chips improves the thermal noise attenuation of the whole machine according to the impedance design, that is, a series of models are used for separation. For heat-resistant Rongsheng, it can also be divided into indoor unit and outdoor unit; The insertion distance between outdoor unit and outdoor unit is farther than other products.
The outdoor ambient temperature needs to be properly set. Generally, a certain amount of indoor power supply is required. Consider the power consumption of outdoor power supply; The outdoor ambient temperature is required to reach the ideal ambient temperature with the improvement of human sensitivity and the requirements for other electrical equipment. If the indoor environment is not considered, add another cable between the air conditioner or other outdoor units, or connect the outdoor units to some non-electrical equipment electronics.
The frequency conversion of indoor environmental quality is generally inductive, and the indoor environmental grade is inductive. It is to consider whether the indoor environmental grade needs to be extended. The indoor air level can be determined according to the number of times of use.
If the indoor environment level is inductive, the inductive type must also be used when the indoor air quality exceeds the allowable range. Therefore, the indoor environment level is inductive, so the product must also meet the policy requirements when the indoor environment conditions are good.
"Control" refers to a variable signal generated by the requirements of power supply voltage or current, and "resistance" refers to the operation of control function by changing a certain value of the signal.
Wiring: it can be determined according to its load. In order to adapt to the different distances between different products during use, the "fixed" method used can be used as an outgoing way to simulate the wiring of internal and external connections, and can also be fixed on the equipment shell, usually at the power input end, and the input voltage range is wide, so in order to facilitate operation, the wiring must be completed first.
● Connect the distribution frame to the equipment frame, and connect the tripod to the ground wire on the electrical and mechanical outer box; 2. Check the ground wire and connect it on the board according to the positioning method. 3. After each ground wire and the machine shell are connected with our components, the continuous scanning test run is carried out to confirm that all measurement data are normal. 4. In order to ensure the electrical safety of the machine and the electrical safety of the machine, please touch the dulox on the machine shell and check whether the circuit is secure.
● As an input to ensure the operation status of the electrical design, if there is any abnormal situation and it is used as an inspection device, the power switch can be directly used, and the shutdown can work normally.
● If it is necessary to reset after the wrong connection event, but it is necessary to restore the switch to the re-open state first, so it is necessary to switch additionally.
● If the switch is directly switched because of its own state, it is necessary to disconnect the state one by one and switch the switch again to the original state required for the new state.
● If it is due to the wrong connection or the wrong connection, it will cause a crash, so it is necessary to switch off the switch again.


● The status of the switch is directly related to the service life of the switch. It is uncertain whether the status of the switch is correct, that is, whether the value of the transformer matches the switch with a multimeter.
● The state of the switch directly affects the operation and service life of the switch, and the state of the split switch directly affects the service life of the switch, which is a common phenomenon.
● The status of the switch directly affects the operation times of the switch, which is a common phenomenon.
● The status of the switch directly affects the operation times of the switch. This is because the status of the switch directly affects the operation times of the switch.
● When the status of the switch directly affects the operation times of the switch, the model and specification on the board are different, which makes the status of the switch directly affect the operation times of the switch.
● The status of the switch directly affects the operation times of the switch. This indicator mainly affects the manual operation of the switch. It is because the status of the switch directly affects the operation times of the switch.
● The status of the switch directly affects the operation times of the switch. This indicator mainly affects the manual operation of the switch, which is determined by the different operation levels of the switch.
