Chengdu is the most professional Lightbox production company the [Sichuan liter advertising】 Chengdu Lightboxes production

Most professional light boxes production company in Chengdu [Sichuan liter ads] the Chengdu production Lightboxes | | Chengdu billboard production | | Chengdu image wall production | | Chengdu Crystal word production | | Chengdu production Lightboxes | | Led light box how to make with the electronic industry development, led light boxes gradually into our lives, maybe you saw it feels very ordinary, but you know the Chengdu led sign production ed the Lightbox is how to make this? today to tell you led secret Lightbox: 1, led light boxes production: black aluminum composite panel, PVC board, acrylic board, plastic board, or other insulating material, words or patterns of play you want to display with an electric drill or engraving machine, the size of the hole to make bright tube tightly insert. 2, light pipe grouping (string) are grouped in series: in accordance with Schedule various colors of bright tube not more than the maximum number that can be connected in series, each series red light, for example tube should not be more than 96 --- 105 / groups, each series bright blue tube should not be more than 59 --- 63 / group, each series green lit tube should not be more than 66 --- 70 / group. Note: Schedule "#" Canada does not recommend use of easily cause circuit instability when the the series bright tube number close to or more than the number with a "#", should be divided into two groups tandem bright tube or more plurality of sets of series light pipe, and then put in each group the bright tubes in series are connected in parallel as a group. Connection resistance: as shown in the Schedule of the appropriate number of resistor string into a series of bright tube resistance without the positive and negative points, one end of a series of bright tube extraction electrode resistance: "-" (negative ) pole, a resistor the other end to the negative electrode of the light tube controller (resistors must connected to the controller on the negative electrode). The bright tubes each branch current best adjust 19mA ± 1mA, resistance selection 1k/2w, 5k, can use five resistance of 1K, power 2W resistor string together connect. Connect the controller: Public Access Controller series bright tube cathode positive (red line) end groups tandem bright tube leads to negative access controller control negative (green line, the yellow line, black line , a white line) terminal. 5 debug: check the connection is correct, will light up after power, simple methods of measurement, a 1K resistor voltage 50V DC voltage with a multimeter file, measuring about 15-20V (preferably less than 18V), exceed 20V to increase a 1K resistor. To facilitate debugging measurements can be connected to the controller pattern the long delay intervals status, the controller output for long bright, short off state. Line debugging and hot-melt gun to seal the entire line hot-melt plastic insulation, to prevent leakage, short circuit unsoldering.
