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 them strips led are equal, by this is very important that at the time of purchase a know their features main and can differentiate between a strip of good quality and another of bad quality. Obviously the use and the type of installation of the Strip led largely determine the money that we should invest in it so rush with assurances its role
The price does not it is all
The price of led strips has to be linked to the features requiring the luminaire according to its mission, a strip led economic does not have to 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.
From the democratization of the lighting led to the sector “not professional” and to homes in general, the demand of strips led is to multiplied being able is buy in crowd of shops and large surfaces to prices really low. However the high competition of the sector forces to many companies to enter in a war of prices, which many times ends reducing the quality of the product to can compete.
5 + 1 determinants of quality
Is very difficult differentiate strips of bad or good quality to simple view, as may seem exactly equal; However their components are very different and these are that determine the quality, the performance and the price end of the Strip. The low quality of those materials can cause that it pulls led illuminate with less intensity, with bad quality of light, or that is “burn” to them few months of use.
Let’s see the main factors:
1. Board PCB.
Its quality is the factor fundamental 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 on sale:
- Transmission of power: 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.
- Dissipation of heat: Temperature is the main factor to determine the duration of the LED chip. When a chip is heated in excess reduces its benefits and its longevity. A PCB thickness helps to dissipate better the heat, while one slim can cause the overheating of the LED.
- Resistance to them breaks: A PCB too fine would determine a strip very fragile and difficult of manipulate, since could cause breaks and short circuits to the fold the Strip for its placement.
In short, with a too-thin PCB we will obtain a fragile Strip and lead leds low-sheen and a high risk heat build up and the led chip failure.
The high value of the copper makes that the PCB is the first affected to the reduce costs, by which is very easy detect when a strip has little copper; are very cheap.
2. CHIP LED
The diodes, which are the Strip light emitters are mounted on chips. The brand and manufacturing of these Chip LED determines the quality of the light and the duration of the strips. Reference marks as EPISTAR, Samsung and create offer the maximum guarantees of lighting and durability. A Led of high quality is between 30 to 50% more shiny that one economic and also contributes to our luminaire:
- High level of CRI, which gives colors more vibrant, deep and real.
- Greater consistency in the color, not will have tonalities different between strips of the same type.
- Longer life. Durability close to the advertised specifications
A LED of low quality has less brightness, low CRI (producing colors opaque or without life) and a high probability of failure shortening your life useful.
3. Electronic resistors
Them strips LED feature with small resistance internal that limit the current that comes to them diodes LED. 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 can find a coating more durable, transparent, flexible and with a greater resistance to the colouring.
It reduce costs can affect even to the glue of fixation of the part back 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.
A form very easy of identifying strips of low quality, is by its price, if this very below the average, surely is cheap costs in some aspect technical important.
As we see the quality of each 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 them projects require the same quality, as with the purchase of a vehicle, where both their performance and price is decide according to its committed with them strips led passes exactly it 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 summary a little them factors mentioned above and that you must of have in has before buy a strip led:
Strips of high quality
- PCB thickness. Best step of the current and optimal dissipation of the heat
- CHIP LED of 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 bad dissipation of the heat
- LED CHIP generic. Least resistance and brightness
- Resistors inadequate. Construction poor
From LedBox advise measure well them needs of our project or installation for hit in the buy of a strip led that US contribution guarantees and luminosity enough for play to the perfection with its committed without spend of more or stay is short and have that spend two times.
