the 5 biggest complaints about leds! (and their solutions) - led housing manufacturer
LED lights have been around for several years.
Time is not very long, but long enough, has gained an unpleasant reputation.
But is this reputation reasonable?
Unfortunately, the answer for a person living in the LED world is yes.
Obviously, we need to find LED lights for our daily lives.
The task of finding high-quality LED lights is arduous, time-consuming, expensive and a headache.
We interviewed the manufacturer, tested the product and talked to the consumer. The consumers(
I am one of them)
All LEDs have similar problems and our job is to find a solution. 1)
They are too expensive: it's easy to be the number one problem, but that's not the case.
There are a lot of relatively cheap LED lights on the market and you just don't want to buy them.
Since the price has always been an important issue, we first checked the light with a lower price.
The reason why they are so cheap is because they are rubbish, pure and simple.
They send out a strange light, they get hot and stop working, they haven't worked since the beginning, they are made into pieces, without any warranty etc.
At this point, we decided to look at the LEDs with the highest quality and the best design.
Beautiful, consistent, bright lights are also durable.
We found a manufacturer. U. S. A. )
This is almost everything we are looking for in the LED.
After calculation, we found that we can bring these LEDs to market for about $120.
00 each bulb, great as no one will buy it. Why?
We looked at the Yugo version and the Ferrari version of the led, we need the Ford or Toyota Camry version.
Long lasting, well-made, reliable, consistent in color and output, but also good in price.
Looking for three years!
We are proud to bring these products to market for $40.
In the $70 range, they were told they were still too expensive.
Obviously, there has to be some teaching about how much life and energy efficiency can save a person in the long run.
For example, one of the lights, the LED par 20 can save a person about $336 over the lifetime of the bulb. 2)
They are prone to collapse: the incidence of an unexplained failure of the LED light suddenly is high.
They sparkled a minute ago, and you only have 60 dollars of paperweight for the next minute.
This is very strange because almost every LED manufacturer claims a life span of at least 30,000 hours.
There are basically only two reasons for this sudden failure: voltage spikes and heat. Voltage spikes(
Really should be called peak energy)
Frequent or excessive LED failures are often required.
A frequent example is in mountain towns where many power outages have led to an increase in generator use.
Direct lightning strikes and failures caused by power companies are examples of excessive voltage peaks, both of which are very rare.
The main cause of LED failure is fever.
Nothing kills the LED faster than fever.
That's why most LED lights have radiators.
A radiator is the term for transferring heat generated in a solid material to a component or assembly of a fluid medium, such as air or liquid.
The radiator usually uses its extended surface (
Usually aluminum fins)
Increase the surface area of contact with air.
The radiators can be so complex and bulky that it is clear that they cannot be sold separately, but must be sold as part of a unit.
The problem with most LEDs with radiators is that they are usually placed in recessed jars.
Unfortunately, this enclosed space will hold the heat that the radiator is trying to drain.
We have come across an interesting idea to dissipate heat with higher efficiency.
These standard lights (
LED Par 30 is considered the best)
The lights installed fans in their base.
The fan is very identical to the one built into the IBM laptop, with a rated time of 70,000 hours.
Another benefit that the fan gives you is that it allows the replacement of the old incandescent lamp directly without the need to replace any housing parts.
It's as easy as screwing the bulb. 3)
The light color is "weird": it's a double complaint, light color consistency and low CRI.
CRI or color rendering index is a quantitative measure of the color capability of the light source faithfully reproducing various objects compared to ideal or natural light sources.
For example, how pale people look under fluorescent light compared to in the sun.
In response to this situation, only LEDs with CRI of 70 or higher are used.
The second complaint is the consistency of the color.
When you order 12 lights, you want them all to send out lights of the same color.
LED manufacturing is not an accurate science, so each LED is tested for color and light output.
After testing, they are divided into different shades, warm white, soft white, pure white, etc.
Unfortunately, the range of shades in "warm white" can be large and very distinct.
In order to obtain a consistent uniform color, some companies paid an additional fee to re-classify according to the color on the Kelvin standard.
This means that all warm white looks the same to the naked eye. 4)
They are all made in China: I understand this complaint even though it is not true.
The gold standard for LED lighting is an American company based in North Carolina.
The other good name is Nichea in Japan. Although it is good, it costs only half of it.
Nevertheless, there are a large number of LED lights coming out in China, many of which have problems.
Patent theft, inhuman working conditions, change of ownership and name of the company in order to avoid guarantees and litigation.
That's why it's wise to work with a well-known American or local company.
They will serve as a buffer to reassure you to buy the product as you know you can go to them with any questions. 5)
They don't give enough light: There are two main reasons for the LEDs to darken.
The most obvious thing is that you are using low power led instead of high power led.
Use 30-low power LED lights
60 small LEDs of 5mm, the same as in LED string lights.
These are tightly packed together and emit quite a bit of light.
They have their own use but are not designed to illuminate a large room.
High-power LEDs use a single large chip and are easily comparable to incandescent lamps and CFLs in lumen.
The second most likely reason for the light bulb dimming is that you are cheated.
As mentioned above, LED manufacturers classify their LED for light output, and better companies pay more for higher quality lights.
This does not mean that dim LEDs will be thrown away, and on the contrary, these LEDs will be sold at a lower price.
The same company that purchased the cutting rate led will also use inferior secondary components and outdated designs.
Where they are not cheap is advertising spending and using top packaging.
Therefore, it is sometimes difficult to distinguish between good and bad companies.
I draw attention to these complaints, which are not in any way intended to scare people from using LEDs.
Instead, educate the public that reputable companies are willing to find solutions for these effective complaints.
Every problem faced and overcome will make the LED better.
