LED-dual-Camping-Light
Yellow light to keep night flying insects away.  
ALLED is launching a new patent product at market at Mid of May, which is a dual color LED Camping Light, which includes a programmed dimmer switch to adjust the light between yellow and cool white light. And the yellow lighting function is part of our patent content for this light. Some may become confused that what is the function of the yellow light. To explain it, please you may be mentioned of one situation.

If you have carefully observated your outdoor security night, you may find that insects and bugs keep circling around and around. You will find the same situation for the road light. So image the situation that if you are on camping trip at night, what is your feeling when you are boring by a set of insects? At that situation, if you have our light at hand, you are sure to be free from that hassel.

So you may ask why a light has a yellow light plus will have that effect?
To explain that, first you need to understand why insects are attracted to lights?
People may have the normal sense that insects and bugs will be attracted to lights. Actually it is not the fact, only night flying insects are attacted by lights. So why?

 
There is no single scientific explanation for this behavior, however.Some explanation may be reference.  
One saying it is that, Nigh flying insects are evolved to navigate by the light of the moon. By keeping the moon's reflected light at a constant angle, the insects can maintain a steady flight path and a straight course.
Artificial lights interfere with an insect's ability to detect the moonlight. They appear brighter, and radiate their light in multiple directions. Once an insect flies close enough to a light bulb, it attempts to navigate by way of the artificial light, rather than the moon.
moodlight
 
One explanation is that, Light is treated as the sign to seperated Up and Down for night flying insects. As most insets are living in an environment that are surrounding by plants. So for insects, this is normal sense that, it become darker when more closed to the ground. At the opposite, when higher to the sky, it become lights. Besides, for insects, their hunters are more likely to appear on the ground. So for safety consideration, they will fly higher into the sky. At this sense, the light will be the sign of the high position. So it will be one explanation for reason that insects will be attracted by lights.

 
Actually not all lights will attract insects. Some kind of light radiatioin attracts insects, while some not. Insects are sensitive to a broad spectrum of light ranging from ultraviolet(UV) to red. Color sensitivity in UV spectrum plays an important role in navigation in flying and terrestrial invertebrate animals. Behavioral and electrophysiological experiements found that the insect eye responds to ultraviolet irradiation. This response leads to several different reactions. When insects are exposed to light, they may go toward or keep away from the source of illumination. For example, many insects forage at twilight when blue dominate the irradiance spectrum the sky.
 
A LED is a semiconductor lighting source. Originally, LEDs were introduced as a practical electronic component in 1962 and early LEDs emitted low-intnesity red light. However, modern version are available across the visible, ultraviolet and infrared wavelenghts, with very high bright light.
Based on our knowledge of insect vision and colors across the visible spectrum, it can be assumed that if the LED light emission is towards the higher end of visible spectrum(>550nm), it may be out of the range of vision of most insects. However if the LED light is within the range you can assure that it is visible by insects.
 




 

Add an LED Awning Light to your RV

Add an LED Awning Light to your RV

Adding an awning light to your awning will extent your exterior camping activities scope at night. During the daytime, an awning provides shelter for sun or rain protection, while at night; you can enjoy a BBQ campfire with your family under the awning. But an awning light is needed to illuminate your activity scope.

At market, there is a wide range of choice of Awning light. Except the traditional awning/ annex light, LED Flexible Strip Light can also be used as awning illumination while it has the advantages of dimmable and remote controlled. LED Camping Light can be used for awning applications if you place a great requirement on brightness level. Actually adding an awning light to your RV is quite flexible. As which kind of light to choose, it is determined by the purpose for your awning light and affected by the length or construction of your awning. So before purchasing an awning light, ask youself a few questions, how long is my awning? If I purchase a LED Light ribbon, do I need to cut it apart? Do I need sufficient illumination so that I can cook exteriorly or play cards with my family?

As one of ALLED lighting store’s famous product is a 40 degrees downward illumination LED Awning Light, here we make a step by step installation demo for awning light installation.

Step1, Mark the location where the light is to be installed. Pull the wire from the car battery to the marked location. Cut a hole for wires to go through at your vehicle with an electrical drill. The hole should be large enough for bushings to go through.
Attention: Cut the electricity OFF at the main electrical panel before you do the wiring.


Image2 shows the electrical wire connection from the inside of the vehicle.




Step3, prepare the awning light. Open the package, then you can see one piece of LED Awning Light and the provided screws. Wire the light.

Step4, Screwing the light to fix it.
Before doing that, do not forget to clean the surface of the vehicle for a good appearance. Detach the caps on both ends of the awning light, and then you can see the screwing holes. Fix the light by surface mounting it. Then put back the caps to conceal the screws.

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

LED Camping Light Installation Spare Accessories Usage Guide

LED-camping-light-installation
How to fix a LED Dual Camping Light
Actually when going outdoor to conduct a camping activities, it is hard to find a solution to fix your light. A lantern for example, you can place it directly on the floor or hood it at the top. A UFP kind LED Camping Light for example, it is designed with the magnet design, which you can have seperated parts attach to each. But actually it is hard to find a light with the perfect fixing or installation solution that fixs exactly for the tent/ awning area.
ALLED's LED Camping Light has the advantage over the similar product at market. Because it has really considered the tent/ awning environment. It is designed with a transparent velcro coat, inside which a flexible strip light provides illumination. Actually it is the velcro strape coat that makes its difference at fixing aspect.
Turn to the back of the light,you can see this spare accessories, you can tear them down to have a look. From left to right, you have three pieces of velcro strape, a hooks with velcro strape, a veclro back. When got this light at hand, not every person have the clear idea of how to use this accessories. Here is the brief introduction of this fixing spare accessories usage.
The tent or awning will always included the bracket support structure. But perhaps not every one with this LED Camping Light at hand know how to take advantage of this bracket support structure and our velcro strape accessoies to fix this light. Image above is the demonstration of the usage of those three veclro strape. First tie them down from the light body. Then find a bracket area to round the velcro strape. You should go a few distance to paste every velcro strape. As this light is 1200MM in length, every 400MM to paste a velcro strape is recommend. Of course, you do not have to use out three in total. In some situations, only two pieces of this velcro strape can hold the weight of the light.
After you fix the velcro strape, then attach the back of the light to the veclro strape.
This installation is the "patent" idea, at the market, you hardly find any similar product. As it is so smart that, why not have a try yourself.
Secondly, you can see the hooks with velcro strape.
Nearly every one notice to use the hooks, but not every one knows the details.
The hooks at ends of this LED Camping Light is another fixing solution to take advantage of the tents or awning braket support struction. So how can you settle a distance if the 1200MM is not enough from one end to another end? Here is why this hooks is designed with a velcro strape.
But few people notice that this hooks it is with a velcro strape that can be tie down from the body of the light. When you need to settle a distance, you can tear down the veclro back which is along with the hooks, so that it longers. But the velro back which is tearable is just about 250MM long, if it is still not enough after that, you need to settle it yourseleves.
If you can find a smarter usage method of this LED Camping Light, please enclosed a image to show us. If your solution can be an inspiration, you will get a gift from ALLED.

LED Camping Light Dual Colour Restore Method

LED Camping Light Restore Method
LED Camping Light Restore Instruction
When you get a LED Camping Light at hand, you will receive a portable package bag from us. Open the zipper of the bag, you will see the light accompanied with all of the accessories( cable and cigarette connectors) lying tidily inside. This light is with a 10M cable, so its cable is rounded by a Velcro back, putted in central of the strip light.
camping-led  
The package bag is not for one time usage. For your recycle usage of the package bag, you need to know how to put back the light onto the bag.
But after usage, you may find all things in disorder situation. When restoring the LED Camping Light onto the package bag again, you may come across with the difficulties as followed.
1, The cable is so long that, it is hard to get it in order again.
2, It seems too hard to put the light back onto the package as the restored one is in larger volume than the package bag.
ghj
After usage, hard to restore again?

Here is the step by step restoring instruction of this LED Camping Light.
Firstly bundle up the cable. Taking reference of the crease created before will help to take a right dimension.
Secondly, use the Velcro back to tie the cable into bundles.
you
Thirdly, Round the LED Strip Light. Which radian to take when doing that? Excessively limited radian when rounding the strip light will damage the strip light inside the transparent veclor coat, as there is circuit board inside. But too wide radian is not proper too, because its volume will become so big that you can not put it inside the bag. So take a proper radian when rounding the strip light is needed. Off course you can do adjust at the final step.

LED BA15D Off Pin LED Brake Light

LED BA15D Brake Light LED BA15D Off Pin LED Brake Light
It's critical to have working brake lights on your car. They're a safety feature and a tool of signature to other drivers. A reliable Brake Light display information about the vehicle's presence, position, size, direction of travel, and driver's intentions regarding direction and speed of travel.
Illuminated brake lights indicate your car is slowing down or has stopped, giving other cars -- in daylight, dim light or darkness -- plenty of time to stop so they don't crash into you. Aside from all that, your brake lights unworking will lead to your ticket punishment.


Standardized type numbers are used by manufacturers to identify bulbs with the same specifications. Bases may be bayonet-type with one or two contacts, plastic or glass wedge, or other types such as wire-loop or metal caps used on tubular lamps. Screw-base lamps are never used in automobile applications due to their loosening under vibration. Signal lamps may have clear bulbs, or may be coated red or amber to provide light of the required colours for turn signals and brake lamps.
jk


To choose your right brake light, one thing you should take into consideration is its response time.
Auto world quotes Robert Schumacher once mentioned the response time of a vehicle indicator light as follows“Our research shows that between 37% and 74% of rear-end collisions are preventable by early warning systems. Just 0.5seconds in early warning would reduce rear-end collisions by 60%.
jk

Response time and braking distance

One benefit of LED Brake Light is its significant faster turn on time than conventional signal lamps. LED Signals provide a braking responses between 170 and 200ms under favorable lighting conditions. And up to 300ms braking response under adverse conditions. Note that a 200ms improvement in braking response time is equivalent to a 19.10 feet(1 Feet=12 inches/30.48CM) ?reduction in stopping distance at a speed of 65 MPH.

200ms=19.10Feet.
jk


One benefit of LED Brake Sign Light is its energy efficiency characteristics. The turn on time for traditional incandescent bulbs is adversely affected by reduced voltage at the signal light. If the vehicle battery voltage has reduced to 8V, then the response time of incandescent signal light would enhanced. LED Brake Light at the opposite, it only draws little current of the vehicle battery. So LED longer the time of battery usage out.

The yellow color of the LED dual color camping kit
When you indulge yourself in the cool gentle wind or board vision in the camping trip, have the bug or month ever be the blue invited ,haunting you with constantly “singing”. Nonsense with screaming or complaining, here you can guarantee your tranquility by means of a special color lighting of LED dual color camping kit, which is competent for keeping the invaders away obediently instead of shedding their blood.
Principle for driving insects
Wonder why the lighting of such extraordinary could fight against the enthusiastic insects, the problem will be figured out in the spectrum.
As the secret is a kind of yellow color, with light band in dominant wavelength 580-650 nm which the moth has to dislike naturally. Under such yellow color lighting surrounded, you can keep from nocturnal insects ‘disturbing like the boring moth or mosquito. And the led dual color light is adjustable lighting with gentle illumination, which is comfortable for eye glaring. By the way, please avoid the mix application with fluorescent tube or other light bulb, in case that various waves interfere with each other and lose effect. Unless you miss the camp with moth and mosquito’s circuiting around.
The yellow lighting is gentle for glaring,isn't it?
dual color camping kit vs tradition moth repellent lamp
May someone would think of the traditional trap lamp for the issue. So, why not makes a arena possible for the LED dual color camping kit and the trap lamp.
1. working principle
While the traditional trap lamp is designed by using the nature instinct of insects’ phototaxis, and mosquitoes would drawn to lamp lights and get deadly electric shock by touching high-voltage-power grid around the outer tube. And it makes use of long wave ultraviolet (UVA) lure source, and its lamp wavelength and UV lighting quantity emitted by the trap lamp will influence the mothproof effect. Mosquitoes, also includes a lot of moths, flies, spiders, etc will all to be the victim will not escape, while the LED one just keep them away by means of the mothproof color ,not to shedding their blood, which is more environmental and there is no need to cleaning.
The trap lamp
2.Impacts on the human health
The impact on the human health should be another focus. As the UV energy of the trap lamp would have something to do with the biology changes. If the skin exposure to the UV for a long time, and the long wave ultraviolet light can deep into the skin.Therefore , the UV gets used to be regarded as one of the factors that cause skin aging and skin cancer. And if the skin exposes to UV for a long time, the eyes would also suffer from lesions such as cataracts and other diseases. Fortunately, the UV containment level of the LED dual color camping kit is low enough to guarantee your relief in the health.
Even though there is criticism about the led’s lighting, whether the light is sufficient good enough for the health, as the Blue-ray just can reach the eye through the pupil, lens and vitreous body retina, which does harm to a degree. But you know it is just for the led lighting with abundant blue , while the color with ordinary blue color , green or the yellow we are talking about, are all safe light sources that will not cause any harm to human body health.
Conclusion
As you can see the comparison of the lighting principle and lighting influence on health, LED dual color camping kitis environmental, appropriate radiation, comfortable for the eye’s glaring, taking a overwhelming superiority in the lighting color. Remember choosing a qualified and environmental camping kit, LED dual color camping kit with yellow color!!

Flexible LED Camping Light with Yellow Light function and velcro back design

In many places in Australia after dusk we are surrounded by bugs and insects being attracted to our bright lights.
