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

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

R&D NEW HOT POINT OF MEDICAL CARE— UVB

R&D NEW HOT POINT OF MEDICAL CARE— UVB

UVB — ultraviolet uv LED strip is the wavelength of 100 nm to 280 nm, which is of great value in the field of sterilization, medical, biochemical detection, high density information storage and secure communication. Compared with the mercury lamp UV light source, based on aluminum gallium nitride (AlGaN) materials ultraviolet light-emitting diode (LED) has the following advantages:Strong, energy saving, long service life, no mercury and environmental protection etc. UVB LED is gradually infiltrated into the traditional application fields of mercury lamp.At the same time, many other applications can now benefit from UVB LED.such as the white home appliances disinfection module, portable water purification system, mobile phone disinfection, etc., thus showing a broad market prospects, becoming the semiconductor lighting LED, the new hot spot of global LED research and investment.it’s  became global LED research and investment new hotspot in subsequent semiconductor lighting Research Report shows that the future of the LED market may be divided into two parts, one for general lighting visible LED; other is a high-tech innovation as the characteristics of UVB ultraviolet LED.Compared with visible LED, the luminous efficiency and the optical output power of UVB ultraviolet LED are lower than visible LED at present. But now we use the nano scale technology to produce nano pattern substrate,not only improved the quality of materials, but also improve the light extraction efficiency.
280 nm ultraviolet LED @ 20 mA current, the output power of the optical output reached more than 3 MW,can also optimize the packaging process, making deep UV LED light beads encapsulated can be achieved morethan 4 mW optical output power.

What about the lot Electric current can be built using infrared LED?

WHAT ABOUT THE LOT ELECTRIC CURRENT CAN BE BUILT USING INFRARED LED?

What about the lot Electric current can be built using infrared LED?
General IR chip processing of the infrared LED can withstand only 4~500mA,preferably at added up to current-limiting resistance.the ir led be electric current under 300 mA in General. VF about in 1.7V the infrared emission tube almost reached the power of peak transmit.under the condition of ir chip with 300mA. All of ir led are subject to the most stringent testing and checking procedures with DC current 50mA.
In instantaneous the current of infrared led can reach the 800mA,then if you use poor infrared led can cause burning or transmit power attenuation fast, the infrared emission tube can withstand the instantaneous current of 1000mA,
but in the current led market, some ir led can withstand the instantaneous current of 1000mA,The solution can solve that problem. of course, the shortcomings of design is battery consumption faster.
