Q:What does patch LED light mean?
Look, what's your product?. Some products have volume requirements, straight line will be relatively large, patches of small affixed to the circuit board does not occupy space, if only the light source, it may be an ordinary light bulb, as LED power saving.
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: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:LED patches have several ways of welding. Which ones can be reflow? What can be done by eutectic welding? Is the welding of viscose and lens material is required?
L electrode for eutectic solder reflow, the other can be used, regardless of the kind of welding, the temperature is not lower than 100 degrees, the flammable soluble materials have strict requirements, depending on whether the welding temperature is lower than the melting point of what you said or. Otherwise, there will be deformation or damage to the material in the reflow process.
Q:Why is the patch LED blue light dim?
When making a batch of LED lights, the brightness values of various lights are in accordance with certain rules. Due to achieve a white balance, three RGB color brightness required by the ratio of 3:6:1, that is to say the blue light required brightness is very low.
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:Patch LED light does not flash, why?
Are you saying that lamp is flashing? You can check the power output, according to your standard parameters and SMD beads, lamp panel series parallel mode, calculate the power output to output power of the test, you may be wrong, power, overload, but also the effective part of you may be the circuit for power transmission is not stable or low
Q:How to detect LED SMD beads
The output voltage of the digital clock diode file is not high, generally below 2.5V, so the measurement of LED lamp does not work, the best way is to external electrical measurement. If there are a lot of beads to measure it, can take a constant current power measurement.
Q:The quality of the LED patch module
Luminous efficiency。 The LM value per watt is called luminous efficiency. This is an important criterion for judging whether LED is energy-saving or not. The incandescent lamp is about 14.4LM/W, the fluorescent lamp is about 51LM/W, the neon lamp is 43LM/W or so, and the LED is up to 150LM/W at present, but most of the LED light effects in our country are in 60~100LM/W. It should be noted that only the white light can achieve such high luminous efficiency in LED, and that red, yellow and blue are generally relatively low (mainly related to human visual definition). But compared with neon light, there is no heavy metal pollution, easy to maintain.
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.
