- Q:What is patch LED?
- Patch LED refers to surface mount LED.The LED is separated from the PCB board in the form of inline and surface mount. Piranha, 3mm lights, and 5mm lights are all pins. While most high-power LED is surface mount, that is, patches. Small power LED also has the form of surface mount such as PLCC-2 and PLCC-4.
- Q:What is the difference between SMT LED packaging with silicone and epoxy resin transparent package? What is the market situation of these two types of packaging?
- At present, it is basically made of silica gel, and the epoxy resin is very few. Only those with lower price may use some. Why is it rare to use epoxy? Because of the use of LED epoxy patch cited some discomfort because the cable used in the above: reflow welding, high temperature resistant epoxy epoxy and silicone not lead to separation, produce decay dead lights etc..
- Q:How many volts is a single LED on the LED patch band?
- The single LED on the LED patch band is around 3.3V.LED light emitting diode, which is a nonlinear component, its operating voltage (tube pressure drop) is also different: ordinary red LED about 1.5 V; ordinary green LED about 1.8 V; bright white LED up to 3.3 V or so.
- 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:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
- 3528-60 is 60 meters per lamp, 3528 SMD lamp with no 5050 light, about 10 watts per meter. Copper wires have less resistance and may be less than 10 watts per meter.
- 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 to detect LED SMD beads
- Now the LED lamp, drop it in general about 3V, so the general multimeter is not measuring it.
- 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:Welding method and notice of SMT LED
- The power of the soldering iron should not be too big. Generally choose 20--35 watt welding time as short as possible, it is best to hang the copper wire on the solder, do not use solder paste in the soldering flux, and choose the rosin as well
- Q:What is the difference in performance between the LED plug-in and the LED patch?
- No difference, because the core of the two is the same, are diode PN junction, but no packaging, the production process is a little different
