Q:How to detect LED SMD beads
Resistance voltage ordinary pointer table 1.5V in general, and some only in the high resistance file (*10K file) with 9V or 15V battery, so the pointer table to measure LeD beads to hit the highest resistance profile measurement, otherwise useless, of course, at this time the brightness is very small, can not see, can only to judge the positive and negative resistance values see.
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
Without heating time, lighting is faster than general light (about 3 ~ 400ns).The electro optic conversion efficiency is high, the power consumption is small, and the energy consumption is about 1/3 ~ 1/20 than that of the bulb.
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:How many volts is a single LED on the LED patch band?
LED patch lamp is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.
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?
To package with epoxy SMD beads are used in a lot of outdoor display, because the epoxy adhesive with good adhesion to all better PPI support in outdoor use, our high quality and inexpensive epoxy epoxy call for samples
Q:Is the forward voltage drop of the patch LED too large or too small?
The pressure drop in the normal range is generally better. The smaller the pressure drop, the lower the power dissipation. The more you save the electricity bill.But not to say that the smaller the better, not in the normal range of low pressure drop products may be defective.In addition, the uniformity of the LED pressure drop is also important.
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:How does the LED patch lamp differentiate between positive and negative poles?
The light emitting diode is fixed regardless of color. The light emitting diode 1, line: foot length is positive, the negative is short. The electrodes inside the tube can also be carefully observed, while the smaller ones are positive and the large ones, similar to the bowl, are negative. 2, SMD: overlooking the side with the color line is negative, the other side is positive.
