by Luz Negra Luz Negra is a pioneer in the design of led strips, offering excellent quality since 2006. We were the first Spanish company to incorporate silicone as an IP protection system and later on to develop our “DUO System” (unique on the market) which guarantees total watertightness yet maintaining the same flexibility and width of the PCB. The exclusive water-tightness system, the double layer PCB, the power stabilizer, the high CRI, the thickness of the PCB, the tin silver in the welding, the quality of the phosphorous in the white leds, the brand name of the chip used, the quality of...

ecoled by Luz Negra Custom made led strips Our vast experience in the design of flexible led strips (since 2006) allows us to manufacture totally customised led strips (according to the order); where the customer can choose from a variety of features, such as the following: PCB width: minimum 4mm. Type of led: front or side lighting, SMD 3014-3528-5050-2835-3327, etc. Water-tightness: from IP20 to IP67. Our waterproof DUO system can also be provided on request. PCB quality: single or double sided, the thickness can vary, light reflecting properties, etc. Led Quality: CREE, NICHIA, OSRAM, EPISTAR,...

Manufacturing process for our flexible led strips Surface Mounted Device led Plastic or ceramic cup Bonding wire (usually gold) Diode Die Cathode contacts (-) (anode contacts on other side) Although the majority of led strips look alike, what makes the difference is the way in which they are manufactured and their components and this is directly reflected in their luminosity, performance, stability, light loss and life span. As follows, we highlight the basic steps which are taken in the manufacturing of our led strips: Diodes where the chips are mounted Base plate with more than 15.000 chips...

Next the chips wires are soldered onto the die (at Luz Negra we use a high purity gold wire which gives us improved conductivity). In order to obtain white leds we need to apply a phosphorus layer on top of the blue led. Depending on the composition of this phosphorus we will achieve different tones of white. Phosphorus is the yellow layer which we can see in the white leds when they are turned off. If the colour is “lemon” yellow then it will mean cold white (approx 6000°K). If it is “orange-coloured” then it will mean warm white (approx 3000°K). Machine soldering with gold wires Test 1x1 placing...

Flexible led strips with HEAT CONTROL Leds are very sensitive to temperature and if we overload, or don’t apply suitable dissipation or if the outside environment is warmer than desired, then the led acquires a temperature higher than appropriate. This means it will enter into a loop where it heats up more and more until it ends up burning out and reducing its luminosity to zero. To avoid these situations, here at Luz Negra we have incorporated our HEAT CONTROL system in some of our flexible strips (PRO series). The heat control works as follows: if the strip is working at its normal temperature...

TM30-18 or CRI ¿Which is more important? The Colour Rending Index (CRI) is a numerical value from 0 - 100, which idicates the quality of light with respect to the sun. A light source with a CRI of 100, supposedly offers a chromatic reproduction similar to that of the sun which means that any product exposed to that light will be seen with its natural colours, as if it were iluminated by sunlight. In the photo we can observe that the hamburger with a high CRI reflects the real colours more accurately, the value of R9 (red) being the most important of all. The CRI with its 15 values (colours) isn’t...

COMPARATIVE Power supply Aluminium profile New Ghost Profiles IP65 connector cable Silicone led profile Opal silicone cover It works at 230V; no power supply required. Side fixing wings We have available CE (LVD & EMC) and RoHS certification _ 254 _

Ghost Profile; our revolutionary product Our Ghost profile is made of opal coloured silicone, which has been manufactured via a cold extrusion process and has a led strip inside which works directly at 230V. Its 140 leds/m and 0.6W of power, use only 0.1W (16% of its nominal). This means they work more relaxed at a lower power level. They do not require any aluminium profile for heat dissipation. This means we can do installation of up to 50 metre with electric feed from only one end and without any junction boxes or drop in tension. Thanks to its waterproofing of IP67 it is ideal for outdoor...

High quality silicone opal profile, manufactured with a 230V led strip inside. It allows us to illuminate cavities and cornises etc. and offers up to 50 metre without luminosity drops. It has 2 side grooves which means we can screw or nail the profile onto the desired surface. Aluminium is not required for heat dissipation and it can work for 24h non stop. It can be cut every 10cm, consumption 14W/m, offering 1500 Lm/W. It can be regulated with triac dimmer. Thanks to its screwable connection kit, welding is not necessary. Its waterproofing of IP67 and UV protection turn it into an ideal product...
