Radio Interference

Radio Interference created by transformer in LED Light application

Radio Interference

A Customer has purchased 1X12V 300mm LED Touch Switch Strip Light in May, 2012. Since our Light is only used on 12V DC, the customer has purchased a transformer. He installed them under cabinet light in kitchen of RV. All the items worked very well for quite a long time. But one day, when he was hearing the pop music and washing the dishes, all of a sudden the LED Touch Switch Strip Light stopped working. The customer checked all the wires in RV and did everything what he could, but they still didn`t want to work. So he sent the items back to us. At first we tried to exchange the light and the transformer, but it did not work at all, then we checked again and found out it is a problem of Radio Interference. After fixing the transformer, all the items start working again.
Our LED Strip Light has a programmed touch switch, the transformer produces the Radio Interference, which will disturb the working of our light when it reaches to a value.

Please be notice that before you buy it to avoid any unneccessory touble

How to choose LED Domestic Bulb

Although LED lights are placing great penetration into market, not everyone know exactly how to choose a right LED Domestic Bulb.? Normal customer will feel confuse how to read the label of a light product. This article aims to give you some information to be a smart customer.
First,which data determine the brightness level of the light, wattage or lumens? Normal customer has the misunderstanding that high wattage indicates the higher brightness level. Actually it is not the fact. When you are purchasing a light, in fact you are purchasing the Luminous flux, so look into the data of Lumens per wattage on the label.
When purchasing a new light, a majority of customer will take reference of the old light which needs to be placed. The brightness level can be calculated by multiplying the wattages data of the old bulb by the lumens per wattage. Then take reference of this data and to purchase the corresponding LED replacement bulb.
Different lighting sources have different illumination efficiency. You can have a look at the form below.

Lighting source
Illumination efficiency (lumens per wattage)
Incandescent bulb 15
Fluorescent 20-25
LED 20 or more

Then, many people have the question, the LED lights claims to be energy efficient, but not know how to calculate its power consumption.
Multi the wattage of the fixture by the cost of electricity in cents per kilowatt hour, then divide by 1000 to get the cost per hour. Take our LED 240V 6W LED B22 Warm White Globe for example, its wattage data is 6W. Then its cost per hour is 6W* 25 cents per kilowatt-hour/1000= 0.15 cents. That is to said, it creates 0.15 cents electricity bills per hour.
You can also taking considering with the purchasing cost of a bulb. Also take the LED 240V 6W LED B22 Warm White Globe for example, you purchase one at $25.14, then its service life is 30,000hrs. Here introduce a concept of depreciation which means the allocation of the cost of assets to periods in which the assets are used. So the depreciation rate of this LED Domestic Bulb is $25.14/30,000= $0.000838=0.0838cents. That is to say, a LED 6W B22 Domestics bulb would cost 0.15 cents of electricity cost and 0.0838 cents purchasing cost per, which equivalent to 0.23 cents per hours.

come and spy on the secret of LED

Come and spy on the secret of the LED

Everyday, you may be surrounded by the LED bulbs, from indoors to outdoors, such as led cabinet light of kitchen, led down light of the public hall, led landscape light along the flower path after sunset, wall washing lighting surrounding the great building, even the automotive lighting on your way back home, the stair light for your leisure hanging around at night.

Gallery for delicated LED
Beauty and Sturdy

Now that everywhere is filled with the shadow of the LED, how much do you know about the strange or familiar lighting friend?

Here we will spy on its secret park ~construction firstly, would you like to come?

As the mainstream lighting in the current led market, ultra bright cool white led would be a great model, which contains three methods for illuminating, such as the Uvled with RGB phosphers , blu-ray single chip with YAG yellow phosphor and the RGB LED. And the blue- leading us into its inner heart area~construction .

Considering the led with two wavelength ( blue-ray single chip with YAG yellow phosphor)which takes a most of the led market.

Let us make one commercial available led G4 bulb under the magnifying glass, what the hell does the world look like in the led G4 bulb? Here we set off the journey!

The inner construction and YAG phosphors
At the first sight of the led G4 chip , here is picture of one chip sealed with clean exposy which is mixtured with YAG yellow flurorescent with the power cut off.
The well-sealed surface of a single LED chip

Under the wiring circumstance, the embeded blue chip light emits blue lights, a small part will be absorbed by yellow phosphor, a large proportion will stimulate yellow phosphor powder and contribute to emitting white light with color mixture.

The animation of the lighting glorious show
With the amount of input current increasing , the luminous intensity will increase.
And please do ensure the input voltage is under the nominal voltage, although the brightness will be raised as the input voltage is increased , the relative life time will be shortened if the input voltage is beyond the rated voltage. 
After the journey deeping into the LED inner park(construction), is there any idea to get a real bulb ,popping up and ruminaing in your mind? What if you go ahead for the 12V LED G4 bulb, it can be another happy experience worths being remembered.

The halogen one awaitting the replacement
3. Reach out for the LED BA15d parallel bulb or LED T10.
Take the LED T10 bulb for model but the LED BA15D parallel pin bulb is optional also.
4.Plug the bulb in the socket
Just insert the bulb into the socket
5. Connect the electricity to check the real illumination situation. Do the self-test (with the broomstick) or get a friend or a large mirror situated so you can see from the driver's seat whether the brake lights go on and when you apply pressure to the brake pedal.
The lighting situations piror to "off"status
6. If it works well, put the integrated light into the original setting place

Something about JAYCO LED Light
Wide range of application
JAYCO LED Light, you can call it LED T10 bulb or LED wedge bulb , is a economical choice to take place of traditional halogen, which supply multipurpose ,including cabinet down, caravan, motor homes in the condition of 12 volt. Counting on the creative product, you can reach out for brightness at ease, no matter in exterior and interior environment.
The application of JAYCO LED light
special ponit
As the name called, the LED wedge bulbhas a specialized socket with wedge shape matched, and the installation of the well-design wedge socket could never be a headache, with the appropriate wiring connection, bright white light draw minimal current and definitely be cool.
comparision of power consumption
Undoubtedly, the reason why LED T10 bulb has become a new and hot lighting application instead of halogen light, of course, counts on its overwhelming superiority of higher efficiency and less heat generating. In the course of examination, the comparison in heat rating is as well huge to a extent, The old one is always the criminal committing hurting, and thanks to its great enthusiasm, somebody needs cool water immediately, because the rather part of the electricity has been transformed into heat power. On the contrary, the surface temperature of the led T1o bulb is as gentle as the sunshine in spring, haunting you whether to leave or not. The detailed data as below:
Technical data of Halogen bulb as above
Technical data of LED wedge bulb as above
The operating voltage is set in 13.5v, when the lightness level of the two lighting generations reach 200 lumens, LED T10 bulb cost 190mA while the power consumption of halogen is up to 1500mA, their power consumption rate could stretch to 1:8, that is to say, compared with one halogen light bulb, the led wedge bulb has eight times continuous lighting with the identical power consumption. Obviously, the JAYCO LED light gains the complete victory in the use efficiency, which reduces lens distortion. By the way, compared to the halogen light, the new generation has no filament to break, and more durable owning long life span to 50,000 hours.
conclusion
