- Q:Welding method and notice of SMT LED
- I recommend reflow soldering under normal conditions and manual welding only when repaired. 2 manual soldering electric soldering iron maximum power can not exceed 30W, welding temperature is controlled within 300 degrees, welding time less than 3 seconds. 3 do not touch the colloidal iron welding head. 4 when the pin is heated to 85 degrees centigrade or higher than this temperature, it can not be pressed. Otherwise, the welding will be broken.
- Q:What is the principle used in SMD LED lamp, should pay attention to what the problem?
- LED white is the light emitting diode, a PN junction to the most important use of SMD beads is the heat, according to the different manufacturer beads, glue package is not the same, should pay attention to pre baking time and temperature, the latter should pay attention to the patch temperature, the most important is the price, many manufacturers in order to cost savings, internal chip used is too small does not meet the standards, support steal frugal material, with iron, the failure cycle shortened, LED lamp can not reach the ideal effect. Again, the LED supply current must not exceed the rated value, which is an important factor in damage to lamps and lanterns
- Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?
- The ten patch LED lamps are connected in parallel with rated power of 5 watts and voltage 3.3V.
- Q:The quality of the LED patch module
- Luminous efficiency。 The LM value per watt is called luminous efficiency. This is an important criterion for judging whether LED is energy-saving or not. The incandescent lamp is about 14.4LM/W, the fluorescent lamp is about 51LM/W, the neon lamp is 43LM/W or so, and the LED is up to 150LM/W at present, but most of the LED light effects in our country are in 60~100LM/W. It should be noted that only the white light can achieve such high luminous efficiency in LED, and that red, yellow and blue are generally relatively low (mainly related to human visual definition). But compared with neon light, there is no heavy metal pollution, easy to maintain.
- Q:Patch LED manual welding, how can welding not burn lights?
- When soldering, the temperature is best to be lower, and the average welding temperature is about 360. That's enough, because the melting temperature of the tin wire is about 220 degrees, so if it is allowed, the temperature can be reduced as low as possible.
- Q:Patch LED market conditions
- Patch LED (SMD LED) is mainly used in lighting systems, decoration, electronic equipment, indicators, backlight, monitors and instruments and other fields. The decline in handset and LCD TV production in 2009 could affect the supply expectations for such components.
- Q:What does "1210" mean in patch LED?
- 1210 refers to the lamp specifications.LED common lamp specifications and parameters of patch0603, 0805, 1210, 3528, 5050 refers to the LED lamp belt, often used in light-emitting components ----LED size (English / Metric) name, for example, 0603 refers to the length of 0.06 inches, width of 0.03 inches. But note that the 3528 and 5050 units are metric
- Q:What are the storage requirements of SMT patch LED (LED)?
- Keep in storage- the original sealing bag packing in the condition of the <40 C and <90% RH degrees for 12 months, more than the storage period will bake.Please check the leak before opening the packing bagIn opening the sealed bag, should be placed in SMD LED and C 60%RH. < < 30 degrees under the conditions in the above conditions, SMD LED must be in the open package using reflow within 24 hours. If placed more than 24 hours, you need to bake- baked, SMD LED in C + 80 degrees 5 degrees C and <=10%RH relative humidity in the oven for 24 hours• remove the pouch before baking, and do not open the oven door frequently
- Q:How does the LED patch lamp differentiate between positive and negative poles?
- The light emitting diode is fixed regardless of color. The light emitting diode 1, line: foot length is positive, the negative is short. The electrodes inside the tube can also be carefully observed, while the smaller ones are positive and the large ones, similar to the bowl, are negative. 2, SMD: overlooking the side with the color line is negative, the other side is positive.
- Q:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
- LED patch lamp with 3528-60 beads should be 4.8W/ meters.Because the LED light belt is made according to the manufacturer's standard, the parameters are different, and the parameters of the LED lamp belt and the method of use are best connected with the manufacturer's confirmation. Some common parameters are given here for reference only
