Q:What is a light belt?
The light belt is the abbreviation of the LED light belt. Most people are not accustomed to the noun when they say it is too long, so the LED in front is omitted. It is called the light belt directly. In this way, the band with the name also includes a lot of big, second line, big three lines, round, second line and so on, the direct use of wire to connect LED, instead of FPC or PCB old band, of course, also includes flexible light band and hard light belt.
Q:What is the difference between a flexible Led band and a hard lamp?
4, each three LED constitute a loop, you can according to the length of demand in the loop cut.5, power saving (energy saving to 90%), low heating, low energy consumption, pollution-free, beautiful.6, the surface of the glue or waterproof casing.
Q:What is the material of LED lamp belt?
The basic concept of LED: LED (Light, Emitting, Diode), LED is a solid state semiconductor device, which can directly convert electricity into light. The heart of LED is a semiconductor wafer with one end attached to the LED lamp strain on one bracket, one end with the negative electrode, and the other end connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin. Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a "P-N" junction". When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of LED luminescence.
Q:Why does the LED band suddenly go dark?
LED product quality problems:1, the use of LED chip poor physique, brightness attenuation faster.2, the production process defects, LED chip heat dissipation can not be derived from the PIN pin, resulting in LED chip temperature is too high, chip attenuation intensified.
Q:What is the principle of LED dimming, which dimming mode is used in LED dimming?
Packet control: the grouping of multiple LED is controlled by a simple grouping device.Control mode of constant current power supply for LED dimming.
Q:Why can't the LED light band be broken from the fracture, but it can be light from the middle?
In order to ensure the brightness of the LEDs in the LED light band, the diode is usually connected in series. There are two possible reasons for the phenomenon:1) when one of the diodes is broken, the entire LED light band will not turn on;2] more diodes in series require a higher power supply voltage, and when the voltage is low, the entire led band will not turn on.
Q:What kind of power supply should the LED light belt be equipped with?
LED lights should be configured with dedicated DC power supplies.DC power supply is divided into two kinds of voltage source and current source;In general, a fixed number of LED lights can use a DC voltage source, the voltage source is relatively simple, many varieties, the corresponding LED lamp group should work in parallel. If the LED lamp group is connected in series, once one of the circuit breaks, the fault will be caused, so the light is not on.
Q:How many volts does the LED light belt need to start?
General LED lamp belt is 12V, 3 beads and a resistor in series, a lamp minimum starting voltage of about 3V, almost 3 9V, although it is lit up, but the brightness is very low, want to achieve higher brightness or to 12V, then 9-12V lamp belt between the lights. Of course, some factories also have 24V, and the same principle.
Q:PCV flame retardant material toxic? (LED background light band)
This band of material itself is made of rubber, and all the glue is with formaldehyde, want to go to formaldehyde, there are two ways, one is to buy. Activated carbon sucked, and the two is the doors and windows open, so that the room ventilation.
Q:How do you cut the LED light belt?
There is a pair of scissors on each of the 10 centimeters of the lamp, where it is to be cut;
