led lights advantage
1, soft, can be like the same curly cord.
2, can be cut and Yan Jie.
3, the light bulb and the circuit is completely covered in flexible plastic, the good insulation, waterproof, safe to use.
4, weather resistance and strong.
5, easily broken, long service life.
6, easy to make graphics, text and other shapes; has been widely used in the decoration and lighting of buildings, bridges, roads, gardens, patios, floors, ceilings, furniture, automotive, pond, underwater, advertising, signs, signs.
led lights with life
1, since the LED is a constant element, so different manufacturers to produce LED lights with constant effect is not the same, of course, life will therefore vary.
2, toughness LED lights with copper wire or a flexible circuit board with LED lights, it might lead to breakage when bent, will also affect the life of LED lights.
3, power supply factors, LED lights generally used constant voltage power supply (DC switching power supply) power supply, if the power output is unstable, or there is no surge protection, will be outside the network when the output voltage fluctuations and unstable voltage current, resulting in LED lights with work in non-standard voltages, will affect its life.
Lights with Features Editor
Circuit design
led lights with the most commonly used size is two voltage 12V and 24V, 12V three series of multiple parallel structure,
24V 6-string multiple parallel structure, the led lights use to connect each lamp can be connected with a specific how long, and the thickness of the design when the line width and copper have a great relationship. Because the unit area can withstand the current intensity is related to the cross-sectional area and the line, if not taken into account when wiring this, then the connection is longer than the line can withstand the current, the lights will be because of overcurrent fever, at the expense of the board, while also reducing the led life.
Production Process
Because LED lights with a series-parallel structure, so when a group loop happens when there is a short circuit, it will lead to other LED voltage same group increased, LED brightness will increase, along with the corresponding heat will rise . Most notably in 5050 with lights inside, 5050 lights when any of them a chip short circuit loop, it will cause a short-circuit current of the lamp beads doubled, that becomes 20mA 40mA, brightness lamp beads become very bright, but at the same time heat will surge, a serious burn circuit boards in a few minutes. But this question because it is relatively obscure, general less likely to pay attention, because a short circuit does not affect the normal luminous lights, if the employee is responsible for testing whether attention LED light, not to check the brightness of the exception, or is not visual inspection, measuring only then tend to ignore this problem, which is why a lot of LED lights with the manufacturer always complained that the products meet customer fever but no cause lies.
Solution:
1, circuit design: the circuit wiring as much as possible so that a wide enough spacing between the lines there is enough 0.5mm, preferably all of the remaining space filled. The thickness of the copper foil as much as possible in the case of customers without violating the total thickness of the circuit board requirements thickened, general thickness is 1 ~ 1.5 OZ
2, the production process:
A /, solder paste printing time try not to let have bridging phenomenon between the pads, avoid the bad welding caused by a short circuit occurs printed;
B, when the patch to avoid short-circuiting
Check before placement position C, reflux
D, do first appearance after reflow inspection to ensure that lights do not short circuit before measuring the review, attention LED lit when there is no review or abnormal abnormal bright dark phenomenon.
