Q:What determines the brightness of the patch LED?
The brightness is consistent over a short period of time, that is, only by considering current and voltage consistency.Long term brightness is consistent with the consideration of the spacing and heat dissipation of different circuits. Uneven heat can also affect brightness.
Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?
Shunt split current series split voltageIs your single lamp voltage rated voltageIn addition to the red and green LED lights, the voltage is between 2 and 2.4, and the other colors are 3 to 3.6V
Q:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
LED patch lamp with 3528-60 beads should be 4.8W/ meters.Because the LED light belt is made according to the manufacturer's standard, the parameters are different, and the parameters of the LED lamp belt and the method of use are best connected with the manufacturer's confirmation. Some common parameters are given here for reference only
Q:Indoor full color LED display module and LED what is the difference between a full color?
(1): LED full color light emitting module display module is generally yellow green, pure green module price is more expensive; SMD full color LED display using pure green tube coreThe display module (2): LED full color pixel visual feeling is thick, low brightness, easy to have the mosaic phenomenon; patch LED full color consistent, high brightness;(3): maintenance module LED full color display is not easy to maintain, the whole module replacement cost is high; SMD full-color LED screen for easy maintenance, repair and replacement of single lamp;
Q:Patch LED market conditions
Chinese suppliers also offer mature, but less profitable two-color and trichromatic products, which are mostly used in backlighting, appliances, consumer products, consumer electronics and display. Despite low market demand, vendors continue to offer sideview SMD LED, including 335 (4008), 020 (3806) and 215 (2810)
Q:How do led patches measure good or bad?
LED patch how to measure methods: use two meter meter test, red pen is positive, black pen negative, if there is "bee" sound is bad, if the light is good
Q:Notes on patch LED
Clean, do not use an unknown chemical liquid to clean the patch LED: an unknown chemical liquid may damage the patch LED. When necessary, immerse the patch LED in alcohol, less than 1 minutes at normal room temperature, and dry naturally for 15 minutes before starting to use
Q:Patch LED manual welding, how can welding not burn lights?
The welding speed and welding time because certainly give light foot heat, so the speed must be fast, tin wire and tip with better, while heating to tin iron head, avoid heating time is too long.
Q:What is the difference in performance between the LED plug-in and the LED patch?
1, the patch is relatively easy to heat dissipation, can be directly welded on the aluminum substrate, heat faster.2, in general, there is a straw type shell, general lighting has front facing directivity, just look at it, brightness will be the biggest. The patch has a relatively wide divergence angle and is more suitable for fluorescent lamps.
Q:Patch LED features
The principle of luminescence is that of cold luminescence, not by heating or discharging light, so the component life is about 50~100 times longer than that of tungsten filament bulb, and about one hundred thousand hours.
