- Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
- They differ in form and belong to the SMDLED category. Encapsulation uses liquid silicone and epoxy resins as well. The patches are basically made of epoxy resin. Relatively speaking, the amount of liquid silica should be relatively large.
- Q:What is the difference between patch LED beads and LED beads: General
- Patch is a LED lamp, 0805, SMD beads 3014, 3528, 2835, 5050, 5630, 5730 and so on.
- 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: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:Patch LED light does not flash, why?
- Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.
- Q:What is the principle used in SMD LED lamp, should pay attention to what the problem?
- Table 1, contact electrostatic protection LED product should be covered with protective electric tape, and its reliable grounding; 2, personnel shall wear groundstrap in contact with LED (best for cable, protective gloves, anti-static ring) allows better wear anti-static clothing, anti-static shoes and static electricity cap; 3, the application in the process of exposure to LED equipment must be reliable grounding, such as iron, shearing machine, bending machine and welding equipment. Conditional still can install plasma fan to eliminate electrostatic; 4, in use or when designing electronic circuit, must consider the harm that excessive current has to LED
- 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:Patch LED manual welding, how can welding not burn lights?
- First of all, welding LED and other electronic products with line electrostatic ring, to prevent static light.When welding the patch LED lamp, first add the tin on the pad of the lamp board, then clamp the LED patch lamp with tweezers. Then, the soldering iron will melt the tin of the solder plate of your lamp board, and then push the LED lamp onto the pad with tweezers. The whole welding process should not exceed 5 seconds, otherwise it will burn the lamp easily.
- 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.
- Q:How many voltages and how many W drivers are used in series and parallel connection with 20 1W patches LED?
- The voltage problem is determined by the size of your POWER SUPPLY, according to Ohm's Law: the series voltage is accumulated and the shunt voltage is the same.
