Purchasing a led is not easy, a number of aspects will determine if our Strip led will accompany us for years or “killed” in a few months. Let’s see what.
Not all the led strips are the same, therefore it is very important that when you buy one you know its main features and you can tell the difference between a strip of good quality and other poor quality. Clearly the use and the type of installation of the Strip led largely determine the money that we should invest in it to make you rush with assurances its role.
The price isn’t everything
The price of led strips has to be linked to the features requiring the luminaire according to its mission, one economic led Strip does not have that give poor service provided comply them with the minimum requirements required for your job. So let us the idea, you won’t have the same light requirements and protection a strip led to be recessed in a showcase that one destined to adorn the exterior of a home.
Since the democratization of the led lighting to the “non-professional” sector and households in general, the demand for led striplight is a multiplied can be purchased at many shops and supermarkets at prices really low. However high competition in the sector forced many companies to enter into a price war, which often ends up reducing the quality of the product to be able to compete.
5 + 1 determinants of quality
It is very difficult to differentiate between strips of good or bad quality at first glance, since they may look exactly the same; but its components are quite different and these are those who determine the quality, performance and the final price of the Strip. The low quality of materials may cause the Strip led lights up with less intensity, with poor quality of light, or that “burn” a few months of use.
Let’s see the main factors:
Its quality is the key factor to determine the duration and quality of the Strip led. It is a copper that runs along the Strip and plate on which van mounted the LED CHIP. Its main functions are to carry the current that feeds to the LEDs and uneven heat that generate them.
The quality of PCB is normally given by the thickness and the width of the plate, the more thick and wide is, the greater the amount of copper that has.
The concentration of copper in the PCB boards has 3 benefits for LED strips:
- Power transmission: A thick PCB has a greater volume of copper, allowing to transmit power by strip more easily ensuring more and better lighting. More slim is the driver, the greater the loss of voltage losing brightness at the end of the Strip by the voltage drop.
- Heat dissipation: temperature is the main factor to determine the duration of the LED chip. When a chip overheats it reduces its performance and longevity. A thick PCB helps to better dissipate heat, while one slim may cause the overheating of the LED.
- Tear resistance: too fine a PCB would determine a strip very fragile and difficult to handle, since we could cause breaks and short circuits when folding the Strip for placement.
In summary, with a too-thin PCB we will obtain a fragile Strip and it will lead to low-sheen and leds with high risk accumulation and failure of the led chip.
The high value of the copper makes the PCB the first affected by reducing costs, so it is very easy to detect when a strip has little copper; they are very cheap.
The diodes, which are the Strip light emitters are mounted on chips. Mark and manufacture of these LED Chip determines the quality of the light and duration of the strips. Brands such as EPISTAR, Samsung and believes offer the maximum guarantees of lighting and durability. A high quality Led is between 30-50% more bright than one economic and also contributes to our luminaire:
High level of CRI, which gives colors more vibrant, deep and real.
Greater consistency in color, do not have different tones between strips of the same type.
Longer service life. Durability close to the advertised specifications
A low-quality LED has less brightness, low CRI (producing colors opaque or lifeless) and a high probability of failure by shortening its useful life.
LED strips have small internal resistance that limit the current reaching the LEDs. In strips of good quality, the resistances are calculated so that the LED current is the ideal. However, low quality led strips “makeup” the use of chips from poor quality providing one current higher than the ideal to make more shine the LEDs seeming more strips of higher costs; the problem is that current excess strips to deteriorate rapidly and reduce its luminosity and life dramatically.
A coating of poor quality or poor does not have chemical protections due to extend the life of the material used, so it can be hardened by heat effect and produce cracks, reduce its transparency and also can coloring of a yellow tone in a short time, due to degradation of the coverage. This may cause water and other elements to affect electronics LED, producing failures. In strips of good quality we can find an overlay more durable, transparent, flexible, and with a greater resistance to staining.
Reducing costs can affect even adhesive mounting on the rear side of the strips. High quality strips, usually uses a special brand adhesive 3M, which is ideal to achieve a reliable fixing on many surfaces. Economic strips often have a generic adhesive, that heat can melt and break off offering a minimum capacity of adhesion.
An easy way to identify low quality strips, is its price, if well below the average, surely made cheap costs in some important technical aspect.
As we see the quality of each of the materials is paid and is important both the lighting and the durability of the Strip, but… is it necessary to always have the highest quality of led strips? The answer is no, depends on 100% of the installation type and functions of the Strip led.
Not all projects require the same quality, as with the purchase of a vehicle, where both their performance and price are decided according to its role with the led strips is exactly the same. Depending on the quality of lighting, amount of luminosity, hours of operation and location of the installation of the Strip led, will have to decide the type of chip, the density of diodes or the IP protection of our Strip.
In a little summary of the factors mentioned above and that you should take into account before purchasing a led:
High quality strips
PCB thickness. Best pace of the current and optimum heat dissipation
CHIP LED, high quality and recognized brand. Strength and 30% more brightness
Good resistance. Good construction and materials.
Strips of low quality
Thin PCB. Less shine and poor heat dissipation
LED CHIP: Generic. Least resistance and brightness
Inadequate heating. Poor construction
Since LedBox is advisable measure either our project or installation needs to succeed in the purchase of one led light that give us guarantees and sufficient luminosity to play perfectly with its task without spending more or stay short and having to spend twice.
