Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
Packaging is for TOP series LED, that is, the type of plastic molding. The patch is based on the PCB circuit board for molding. Mold release agent is used in molding.
Q:Why is the patch LED blue light dim?
If you choose the brightness of blue light in the light of the relatively high, so when debugging the white balance (by changing the resistance to change the current, and then change the RGB brightness LED lamp), it is difficult to transfer to the pure white. Therefore, when selecting the lamp, the blue light is generally not bright.
Q:How does the LED patch lamp differentiate between positive and negative poles?
Because the LED open threshold is about 1.5-1.8V. It is possible that the voltage supplied by the digital multimeter does not activate it. So look at the sign. Patch LED (SMD LED), the green point of negative, relative to the positive.
Q:LED light SMD LED package in what form, trouble you under the guidance of...
The LED chip has bumps and is welded to the PCB board using FLIP CHIP to packaging technology.LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good. Field of application involves mobile phones, desk lamps, household appliances and other daily household electrical appliances and machinery production.
Q:Welding method and notice of SMT LED
The peak reflow temperature: 260 degrees or below this temperature. (surface temperature) 2 temperature over 210 DEG C required time: 30 seconds or less than this time. 3 reflow times: no more than two times. 4 after reflow, LED needs to be cooled to room temperature before contact with colloid.
Q:What is patch LED?
LED lights, a common model, has 34654635285050 piranha.The most common assembly of lights and PCB boards is the DIP, that is, dual in line and SMT surface mount technology two.The 346546 is the LED with two positive and negative pins, which are inserted into the PCB board after cutting the foot;3528 and 5050 are a cube with 3 LED lights inside, known as the "three in one" LED lamp. It has no pin underneath, but has a metal patch that can be passed through the reflow soldering machine through the solder to the PCB board.General indoor LED screen with more patches, outdoor screen with more pins.
Q:What is patch SMD-LED?
Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of LED luminescence. The wavelength of light, that is, the color of light, is determined by the material that forms the P-N junction.
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?
Epoxy resins turn yellow during short wave irradiation or long periods of high temperature, so they are very short lived when applied to high power lighting. That's why the LED lighting market is dominated by silica gel.But because of the low price of epoxy resin (silica gel and not at a level), and storage, use and processing is superior to silica gel, so the low power LED and some optical components still use epoxy resin package.
Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?
The voltage needs to be determined according to the product specification, usually 3.1 - 3.5V
Q:Led lamp and Led what is the difference between the two patch! Ask for detailed explanations of the differences!
If you take a large area light, to see that the lighting requirements, functional lighting, or lighting atmosphere, or ordinary lighting, which is to be considered, the two optical (lens) can bring you the light angle planning.
