Installed indoors, you can directly tear off the stickers on the 3M double-sided adhesive surface, and then fix the light bar where it needs to be installed. Just press it with your hands.
Q:What is the difference between patch LED beads and LED beads: General
A pin of the lamp, and outside a resin cap, because the reason LED beads can spotlight cap;There is no pin on the patch and there is no resin cap outside. Because of the lack of cap, the LED patch can not be concentrated.Patch is based on small power, the shape is relatively small (usually 0.5 and 0.5W products)It's called patch because some small ones need Mounter to machine.The ordinary LED lamp, solder joints than SMD beads, now is the largest artificial welding. Regular watts count from 1-300W
Q:What is the rated current for the white patch LED?
LED high power and low power, small white rated current and LED wafer, such as a chip is 20MA two 40MA.... High power 0.5W, 100-150MA, 1W, 350MA current rating in the relevant product specifications
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
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:LED light SMD LED package in what form, trouble you under the guidance of...
There are 3 types of LED packages: inline LED, piranha LED, and surface mount LED
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:What is patch LED?
LED is usually the lead pins form, need to be drilled on the printed circuit board, the LED pin is inserted in the hole, welded with wave soldering machine; and the patch type LED is used in welding surface, flat welded on the circuit board.
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:Indoor full color LED display module and LED what is the difference between a full color?
The classification of the LED display according to the installation environment: indoor LED display screen, semi outdoor LED display, outdoor LED display; according to color: color LED screen, dual color LED display screen, LED display screen, the color LED display screen; according to the functional area can be divided into graphic screen, screen, screen, screen, digital dot matrix digital hybrid screen.
