In social life, LED advertising around us can be seen everywhere, how is it made? Let us take a look at the production of LED billboards now!
LED billboard production step 1: making switch
1. First select the applicable micro switch (of course, the size is smaller than the model part);
2, because the model glue is thicker, so first use the tool to thin the inside, and open the gap in the appropriate position, to facilitate the exposed button of the switch;
3. Connect the two wires to the positive and negative terminals of the switch;
4. Check if the switch can be properly hidden in the part, and try to see if the part can be correctly assembled.
LED billboard production step 2: LED light connection
1. Connect the two wires to the positive and negative terminals of the LED (usually positive and short, negative, but not the law, so it is best to test);
2, wrap the wire with adhesive tape, so as to avoid short-circuiting the wire (it doesn't matter what glue paper is used, anyway, only 3V voltage).
Note: If used in wet conditions, please use electrical tape for safety reasons.
LED billboard production step three: place LED lights
1. The tip of the gun is made of thin LED lamps;
2. Cut off the position of the gun head and open its position;
3. Since the tail of the LED lamp head is wider and the parts are not so wide, it is necessary to engrave a groove in the part to hide the lamp;
Note: How to hide the light depends on the space of the component itself, so there is no law, everyone can adapt it!
LED Billboard Production Step 4: Select the location where the battery is placed
It is not easy to choose an appropriate location, because there is not much space. This time, a thinner battery (CR1220) is used, which is the kind of PGZeta.
1. As in the past, cut out the unused places, and choose the location because of the condition of the parts;
2, of course, try to put the battery into the space.
LED billboard production step five: making a battery box
Since the size of the commercially available battery cases is relatively large, the materials we need to tailor-made for production are model rubber plates purchased by general model stores.
1. Cut the rubber sheet to a larger size than the battery, and cut out a plurality of strips for preparation;
2, there is no precise measurement tool, so it is necessary to see if the height is appropriate;
3, use the model glue to glue the strip to form a concave word, and then paste the mask to make the shape in the middle of the figure (cut off the excess);
4. Open a hole in the top and bottom for the placement of iron pieces. The iron sheet material used this time is the buckle when you buy socks. This iron piece is quite easy to use, and it is not easy to break when it is easy to bend.
5. Flex the iron piece into a Z shape for easy placement in the previously prepared position;
6. Make the shape of the figure in front and back.
Note: Because the negative pole of this battery is above and the positive pole can be connected to the bottom or left and right sides, but there is a chance to contact the negative pole on the left and right sides, it is recommended to put it below.
LED billboard production step six: connect the battery box
1. Put the battery box in a pre-arranged position, just the size! . .. .. (In fact, the size of the battery case has been good);
2, connect the wires, first connect the wire of the LED fruit side (connect the negative pole to the negative pole of the battery box);
3. Connect the positive pole of the LED fruit to the positive pole of the battery box, as long as the positive pole is not connected to the negative pole;
4. The positive pole of the battery box can be placed on one of the wires of the switch system, because the switch has no positive and negative poles;
5, the old saying often, test it under the test;
6. Twist the switch wire into an S shape, because the handle is movable, and the S shape can provide sufficient flexibility, depending on the space of the part;
7. Put the guns together and try to make the circuit contact bad if you try the gun handle activity. If there is any, of course, make corrections.
LED Billboard Production Step 7: Making a Battery Cover
I believe that everyone has a certain model experience, make a suitable battery cover!
It can be seen that the production steps of this LED billboard are still relatively complicated, but it is relatively easy for professional people. Therefore, as an electronic enthusiast, let us cheer together!
Cylinder radiator
Also called oil-filled heater. This heater is filled with a new type of heat transfer oil, when connected to power, the heat pipe around the heat transfer oil is heated, and then along the heat pipe or loose pieces of heat will be distributed out. When the oil temperature reaches 85 ℃, the temperature control element that is self-power. This kind of heater heat transfer oil without replacement, long life, the price is generally between 400 to 500 yuan. Suitable for use in the living room, bedroom, aisle and the elderly and children's family, with safety, health, clean, tasteless advantages. The disadvantage is the slow heat dissipation, power consumption more. Oil bath heat sink has 7, 9, 10, 12, etc., can be selected by the size of the heat sink to the size of the power, the use of power in 1200 watts or so.
