One, waterproof LED lamp string features:            1, LED lights string, give full play to the advantages of LED point light source, any combination, so that LED external luminous character, large outdoor LED advertising signs, LED electronic light box production is more simple.            2, special bayonet design, directly installed after drilling, installation time is fast.            3, all kinds of board drilling can be used (such as electrolytic plate, aluminum plastic plate, iron plate, stainless steel plate, etc.).            4, using Taiwan famous brand LED chip, with strong brightness, good consistency of light and color, good color saturation, long life and low attenuation, ensure product quality.            5, the use of parallel wiring, breaking the traditional "one lamp is not bright, all lights are not bright" shortcomings.            6, the full color lamp string, using the intelligent control system, can produce gradual change, jump, chase, scan, display animation graphics and other effects, and can realize asynchronous and synchronous control, random arrangement, meet the requirements of different users.            Two, LED light emitting light string specifications:            1. Working voltage: DC5V; DC12V.            2, LED string color: red, yellow, golden yellow, blue, green, white, purple, orange, two colors, seven colors, full color.            Three, waterproof LED lamp string use:            LED lights are used for outdoor lighting and outdoor signboards, which highlight brand and fashion, and greatly enhance the scale and scale of businesses. It is mainly used for building signs, hotel outdoor signs, KTV and other signs, shop signs, doorway signs, etc.            Four, the steps of making LED external luminescent word:            1, LED outdoor signboards need tools: 40W or 60W electric iron, solder, electric drill, glue gun, screwdriver, etc.            2. LED outdoor signboard production needs other materials: punched sheet iron characters, wires, magic color LED light-emitting word power supply.            3, punching: aperture (9mm, 12mm, 20mm), spacing according to the height of the outdoor card installation and production cost, the general LED center distance is: 10 - 30mm, small spacing, high brightness, higher cost.            4. Insert lights: clean up the drilled holes and install the lights one by one.            5, connect: there is a waterproof LED lamp string that has been made and connected, each string has a reserved wire head, the red receives the positive pole of the power supply, the black thread head receives the negative pole of the LED special power supply, and the power supply should be placed in the power supply box. (refer to the installation instructions)            6, test aging: after all the LED is connected, check the treated light, and then do the aging test for 48 hours.            7, transport to the scene, on the scaffolding site installation.            Five. Use of attention:    



1, the voltage of LED lamp string is DC5; DC12 please pay attention to using that type of voltage.            2. The sectional area of the wires drawn from the power source should not be less than 4 square millimeters (or 2 of 2.5).            3, the electronic string of the light string is connected to the positive pole of the power supply (some of them are 2, and then receive the positive pole of the power supply).            4, the electronic string of the lamp string is connected to the negative pole of the power supply (some of which are 2, and then connected to the negative pole of the power supply).            5, if the individual lights are not found, please check the lights or lines. If not, please change the LED lights.            6, two color and seven color LED full color waterproof exposed light string is a common positive pole, and the controller controls the negative electrode.            7, the full color LED exposed waterproofing lamp string four lines in the red is the positive pole, in turn is: positive pole, negative pole, data, clock.            Bags, boxes.
