LED electronic crystal Dijiao signs advertising light box production steps
(1) the size of the aluminum plastic plate is 122*244, and the reasonable use of the size is not wasted. Use the wallpaper knife to cut the appropriate size, and put the design of the customer to the Department of art and paste it on the aluminum plastic board. (I am a hollow character carved with instant spray paint, so the effect is much better than instant stickers. The sun blew out on the sun for a year. The next time the hollow words can be more economical.
(2) according to the character of the font and size, in the words of the center hole pen point in the distance, away from the light pattern in 1.5-2cm. Running all over the light 3cm, to be flexible, the more dense the better. It can also make hollow words better. (pay attention to the distance when cross)
(3) use flashlight or engraving machine to punch and finish the burr.
(4) to install the Dongguan metal sign in accordance with the pattern (+, -) (+, -) in the form of the pattern (+, -), so as to connect it later. Put the lamp in place.
(5) installed first hit half lamp glue in the side, in order to connect. The next picture is to run through the light connection. The corner of the lamp can be settled together but must be reliable. It is better to finish the solder.
(6) the LED lamps in each word or pattern are connected in series, each circuit is not more than 115 in red, no more than 73 in blue, and no more than 80 in green. When a word or a pattern is too large to exceed the number used, add another loop.
(7) parallel between words and words or patterns and patterns.
(8) anti static work must be done in the process of production.
(9) notice that all pins of LED must not be short circuited.
(10) measure the current of each loop to ensure that the current is in 15-20mA
(11) according to the number of resistance patterns amount, the resistance welding wire into the yellow wax pipe string in the loop between any two LED.
(12) Led welding time cannot exceed 3 seconds. (it is best to use a constant temperature soldering iron and a grounding wire.)
(13) connect the controller to watch the production effect. The light box is shown to be packaged and assembled with a rubber stick.
(14) three and (five) the controller output is DC 220V, red, the positive lead beads to the red, the yellow light negative lead word, three green line is the negative pole of Dongguan stainless steel signs all over each pick a color. White is a often bright negative.
(15) 1-2 holes for 8mm leakage at the bottom of the lamp box frame. In the side of aluminum plastic eraser box according to the size of the groove edge drilling screws aluminum plate to prevent the deformation of the panel.
(16) before installation, 48 hours of aging test should be carried out (let the lamp box run for 48 hours) to detect the reliability of the lamp box.
(17) the single led long angle is the positive pole and the short foot is the negative pole. Even the feet of LED lamp inside the chip, the anode is small, is positive, compared with the observation of plant led.
