Q:SMD LED lamp working voltage?
Voltage range of white LED lamp: 3.0-3.4VThe pressure drop of the red LED is 2.0--2.2VThe yellow light emitting diode has a pressure drop of 1.8 - 2.0VThe green light emitting diode has a pressure drop of 3 - 3.2VThe blue light emitting diode has a pressure drop of 3.0-3.4VSMD voltage is basically the same as double lead line. Current is generally 20~60mA, and some work current can exceed 100mA.
Q:What is the principle used in SMD LED lamp, should pay attention to what the problem?
Pin forming, 1, LED pin molding must be completed before welding, bending angle must be more than 3mm of the gel to bend the stent. Pin over 2 times in the same place can not fold number, pin bent to 90 degrees, and then returned to the original position for 1 times; 2, pin forming must use fixture or by professional personnel to complete the first, pay attention to avoid the epoxy body caused by excessive internal wire fracture; 3, to ensure the distance between pin pin forming consistent with the circuit board; 4, when LED has good welding in the welding process or after, please don't bend light feet, to avoid damage to the lamp.
Q:The quality of the LED patch module
Chip manufacturers, the top chip mainly from the United States, Germany, Japan and South Korea and so on. But on the mainland LED module manufacturers to use the vast majority of chip from Taiwan, of course, there are a lot of use of chip, market positioning, the main users of the product features with the manufacturers and government policies, different chip manufacturers are different its stable performance. Maybe you will ask why not CREE, OSRAM, Nichia, first of the world's top chip manufacturers have fixed target market positioning, such as defense orders, and said, specially import a little CREE chip manufacturing module, it is also not cost-effective; and if the driver is not supporting the raw materials, it can not be completely play the advantage, so is also a great waste.
Q:Patch LED features
The seismic resistance, high reliability, low operation cost system.It is easy to small, thin, lightweight, easy to shape without restrictions, made all kinds of application.
Q:Why is the patch LED blue light dim?
The pressure drop of the blue light is greater than that of the red light and the green light. If the series connection is the same as that of the green light and red light, the current limiting resistor will tend to dim
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:What is the rated current for the white patch LED?
The high power 1W is 350MA, and 3W is 700MA. They are all fixed and can be found everywhere.
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:Patch LED beads can be bought in what place?
If you don't want to constantly change with it, suggest you go to OSRAM, Nichia, Corey, Taiwan Tongjia enterprise authorized agency purchase.
Q:Notes on patch LED
Moisture proof, in order to avoid the products in the transport and storage of moisture, SMD LED packaging is moisture-proof aluminum packaging, and packaging bag containing a desiccant and humidity card, mainly to control the desiccant bag, humidity, humidity card is mainly to monitor the packaging bag of humidity
