Cleaning the light box is also an important work, often neglected by some enterprises. It will not only affect the appearance of the light box for a long time, but also affect the interior, especially the damage of the light box circuit. Especially when placed outdoors, often due to the invasion of dust and water vapor in the air, easy to have adverse effects, directly cause serious problems. Therefore, cleaning the light box is very necessary.
2. Regular check-ups
In order to avoid unnecessary trouble, we need to check the box regularly after use. The light bulb will naturally become less bright if it is used for a long time. In order to ensure even brightness of lamps, we need to check the brightness drop of lamps regularly and replace them in time.
3. Failure to maintain in time
When removing the light box, the operator wears cotton and white gloves. Hand sweat contains oil, salt, acid, alkali and so on. Ingredients, corrosive. Adhesion to a stainless steel, stainless steel material surface problems gradually form corrosion, stainless steel surface technology gradually fade and discolor, lose their original beauty.
When removing the frame light box, flat tape to avoid collision and distortion on the ground, frame flat.
Unplug the plug, cut off the power supply, check the students' original living appliances. During the inspection management process, details of wires need to pass through the power cord, between the input and output terminals of the ballast, and the information socket. The size of the light box should be designed to match the size requirements of the light guide plate. It can not be too large or too small to avoid the effect of the display and the heat dissipation of the light box.
When installing the outer frame of the light box, take and put it gently, hang it horizontally, and then close the lower part of the light box and fix it with the inner hexagon screw.
Then check whether the upper power cord of the light box is in the power access slot. If not, please correct it.


The plug power switch is disconnected when the lamp is normally observed. If the indicator light is not on, turn off the power, pull out the plug, check the socket wire, check that the light is loose, the input and output lines of the stabilizer are loose, etc.
If the whole light box is not on, please check whether the leakage protector is closed, whether the quality of the wire joint in the plug is loose, whether the input current management is suppressed, and whether the output joint is loose.
If the leakage protector is turned on, check that the power cord is inserted into the ballast and the lamp tube is not branched-waste liquid.
If the noise effect of the light box is too large, please check whether the electronic ballast is aging.
