LAMP, LED technology KNOW-HOW

LAMP designs, develops and manufactures systems with LED technology at its own R&D&I Department.  Because LAMP controls the entire process, it guarantees the highest quality, reliability and the most competitive price for its LED technology products.

This makes LAMP highly competitive and flexible, and it can meet any lighting requirements with LED technology.

The LED System: LEDs – Circuit Board – Driver – Heat sink – Lens

LEDs: LED stands for Light Emitting Diode. LEDs are semiconductor diodes that emit light when the electric current passes through.
At LAMP the LED modules that are installed in the luminaires are divided into production batches and bins, in order to guarantee an even flux, colour and voltage.

PCBs (Printed Circuit Board): LAMP normally designs and develops aluminium PCBs (Printed Circuit Boards), where afterwards all the electronic components and LEDs are installed, to guarantee optimal thermal management that ensures the quality and reliability of the LEDs.

All the PCBs are installed with SMT (Surface Mount Technology) automatic systems, checked by AOI machines and with strict quality controls of 100% of the production.

Driver: LAMP's LEDs can be supplied by Constant Current Drivers (A) or Constant Voltage Drivers (V). In order to guarantee the useful life of the LEDs, PWM (Pulse Width Modulation) at 350 mA is used, and drivers with minimal losses.

Heat sink: Part of the power that passes through the LED dissipates as heat in the opposite direction to the light. Because of this, suitably sized heat sinks are required to make sure that the operating temperature is the most efficient, inorder to ensure the useful life and luminous flux of the LEDs.

Lens: The lenses enable us to control the direction of the luminous flux. Because the LEDs are so small, we can obtain any type of photometry. It is essential to use the best materials to ensure minimal loss of luminous flux, and minimal colour distortion.

Characteristics of LEDs

1- Longer useful life and less maintenance: The useful life of LEDs today is about 60,000 hours. This enables significant saving of maintenance of the luminaire and to make the most of the installation.

2- High efficiency: Efficiency is the luminous flux emitted for every watt consumed. At LAMP we use LEDs with an efficiency of more than 100 lm/W. This value is constantly being increased thanks to the research we are carrying out in this field.

3- Adjustment: The adjustment of the LEDs leads to an optimisation of the power. We can adjust from 0 to 100% of the luminous flux, so we can use the light we need according to the requirements of each project and moment.

4- Instant light up: LEDs, unlike other light sources, start up with 100% of their luminous flux.

5- Wide range of colours: LEDs can offer a wide range of colour tones, more than traditional light sources. Highly saturated colours and different tones of white (Cool, Outdoor, Neutral and Warm White)

6- High colour rendering: The LEDs that we use have a CRI (Colour Rendering Index) of 80 to 90.

7- Cool light: LEDs transform a large amount of the power they use into light, so the light they emit is not hot. Their cool light avoids burning.

8- Low temperatures: LEDs are more efficient and emit a higher luminous flux at lower temperatures than at higher ones. They can work at temperatures as low as -40ºC.

9- UV and IR radiation-free: They do not emit ultra-violet (UV) or infrared (IR) radiation, which means they can be used in museums or shops to light up delicate objects.

10- Dynamic light: We can create many effects thanks to the management of the light and the colour by control and adjustment systems such as RDM, DMX, DALI and 1-10V.

11- Low voltage: LEDs work with low voltage constant current.

12- Control of the flux direction: Controlling the direction of the luminous flux means that the light can be focused on the area you need. That way light pollution and intrusive light are reduced.

13- Reliability: LEDs are solid objects (Solid State Lighting) unlike other light sources made of filaments and gases. They are reliable and long-lasting.

14- Ecological and energy-saving: LEDs do not contain mercury and their electronic boards are made with lead-free welding, which complies with the RoHS directive.  Thanks to their efficiency they save much more energy than traditional light sources. This reduces CO2 and SO2 emissions, which means that LEDs are environmentally friendly.

15- Creativity and customisation: Because they are small, LEDs enable us to design small luminaires and customise lighting effects that the project requires.


Because of all these characteristics we can say that LEDs, thanks to their combination of durability, efficiency and colour range, are an optimal source to be used both in and outdoors.

There may be better light sources in some respects, but LEDs are without a doubt the best light source if we consider the combination of advantages, and with the highest potential because of the continuous research that is currently being carried out in this field.

LEDs used in LAMP products may be modified because of the fast progress in LED technology. To see up-to-date information, please visit our web site: www. lamp.es
