INSTALLATION INSTRUCTIONS FOR SIDE EMITTING LED STRIP LIGHTS

Installation Instructions forSide Emitting LED Strip Lights
Side Emitting Waterproof LED Flexible Light1 Side Emitting Waterproof LED Flexible Light
* Side emitting LED flexible tape using (120 LEDs)
per metre. This LED tape emits light from the side allowing the
LED tape to be used around curves making it perfect for applications such as signage and light boxes.
* This LED side emitting tage is cuttable every33.3mm
(every 3 LEDs)using scissors, is fully
dimmable and is supplied with a 3M sticky tape
backing for easy installation.
*This side light emitting LED tape operates from
(12vdc and 10 metres) can be powered as a single
length.Longer run lengths are possible by introducing additional
Power supplies.
1. Clean the mounting area with alcohol prep swab.
2. Remove backing paper from two sided tape on back of light. Apply light at desired location and press lightly onto the bike.
3. Connect red wire to desired power source, such as running, brake, or turn signal circuit.
4. Connect Black Wire to proper ground.
5. Test for proper operation.
The advantage of Side Emitting LED Strip Lights:
1, Power saving, less heat, only low power consumption, suitable for any 9-14V car power;
2, Long service life, using this product is imported LED lamp wick;
3,  Fully sealed waterproof design (high quality soft sealed), 100% waterproof;
4, The pressure, shock, impact resistant, soft material, durable;
5,  High brightness, long service life, brightness uniformity, no color, wide coverage

LED constant current source

LED constant current source
The work processes of LED constant current source were described in detail. Connect with the mains to start, the input voltage start to rise, in the moment we found the current reduced, as the he voltage increasing. the constant current source will be able to deal with output voltage when reaching the enactment standard value of current.
Conversely, The automatic lowering of the output voltage when current increasing

TYPICAL CONSTANT CIRCUIT FOR LED


TYPICAL CONSTANT CIRCUIT FOR LED


The hardware scheme use supper bright high power LED and 1W of constant circuit which supply constant output current
1W constant circuit
The sensor resistor is externally connected, which realize output current programmable(R1 is sampling resistance)
Peak current = 500mV/R1

UV LED DEVICE IS NOT WORKING CORRECTLY FOR QUIET ANALYSIS

UV LED DEVICE IS NOT WORKING CORRECTLY FOR QUIET ANALYSIS

UV LED device is not working correctly for quiet analysis
ⅠThe trouble cause by supply power problem
This poles are the key components in a supply power. so the battle line is not allowed to access anti-Line. If the multimeter is used to measure DC voltage or DC carnet, we must be careful that the polarity is not reversed.
please exchange poles at once if not the direction might be wrong;
ⅡSomething is wrong with the uv led module
The uv led module need by strengthening the final inspection and testing to ensure(yet that is exactly what our QC often does. good quality of uv led strip need professional manufacturer).
if didn’t stick product religiously will get into trouble. These are common problems:
1:Iron bracket make heat conduction poor cause the temperature of plate higher, in here we suggests using a copper bracket. In experimenting we find out that the efficiency of white LED using copper brackets is higher than iron brackets, moreover, the light decay is lower about 10%.
2: Epoxy resin etiolated
3: Not compact or dense in led core and led bracket
4: when led core quality is poor, the more the loss of optical power will be
