LED Lights


Lighting up the future

Born to house LED

LED technology requires a good management of the heat release. And when we design our luminaires we know what will be “living” inside.


This is the main advantage of replacing the full luminaire: if the work is well done, everything will be balanced. The space for the electronics, the heat dissipation capability, the possibility to adjust the light angle,…


As you for sure already know, while incandescent lamps (and also other technologies) can exhaust heat through radiation, LEDs produce little infrared heat. As a result, they must be cooled through conduction, or risk, diminished performance in luminance, lifespan, and colour stability.


So our main target when designing a luminaire is how to deal with the thermal management and how to optimize the LED output. And the best strategy here is to turn fixture bodies into integrated thermal solutions and integrate the best solutions for every situation: passive cooling, active cooling and/or hybrid heat pipes.

Junction temperature


Operating an LED above the maximum temperature recommended by the manufacturer can lower the device's efficiency and light output and can lead to premature failure. A LED's hotspot is defined as the junction between p- and n-type semiconductors that form the diode.

Junction temperature is the highest temperature of the actual semiconductor in an electronic device. In operation, it is higher than case temperature and the temperature of the part's exterior. The difference is equal to the amount of heat transferred from the junction to case multiplied by the junction-to-case thermal resistance.


When considering LED thermal management, there are generally three factors that tend to act on junction temperature. These are the ambient air temperature (that will vary by application), the thermal path between the LED junction and the surrounding environment (the thermal path must be optimized to encourage natural heat convection) and the LED's efficiency.


The thermal resistance between two points, which is often measured in ºC per watt, may be thought of as "the ratio of the difference in temperature to the power dissipated." This ratio should be calculated for the LED junction to the thermal contact or solder point typically found at the bottom of an LED package and for the thermal contact to the ambient. The sum of these measurements represents the thermal resistance for the LED as a whole.


Power dissipated "is the product of the forward voltage and the forward current of the LED." To assure satisfactory lifetime of the device, good efficiency, and proper LED colour, junction temperature must be maintained within a specified band. Junction temperature (Tj) may be calculated by adding the product of the LED's overall thermal resistance (R) and the power dissipated (Pd) to the ambient temperature (Ta). Mathematically is: Tj = (R x Pd) + Ta.

New Series 100

The Series 100 incorporates the most advanced cooling systems, the most reliable electronics and the worldwide main LED brands.


If you are looking for peace of mind at a competitive price, Series 100 is your best choice.

Street Lights of Series 100 covers from 48W till 168W LED power built with 24W modules. Each module can be rotated from +6º till -6º in order to adapt the light direction at each point of one street without changing the aesthetical of the poles alignment. The luminaire's arm is also adjustable from +6º till -6º providing great versatility.


The external housing is done of Acrylonitrile Styrene Acrylate (ASA) that is much more suitable than ABS for outdoor uses because has great toughness and rigidity, good chemical resistance and thermal stability, outstanding resistance to weather, aging and yellowing, and can maintain the high gloss.

3elamp's new 100 Series of Sealed Floodlights covers from 100W till 500W, the most powerfull unit available in the market. Its housing (with 216º adjustable angle) integrates the best tecnologies of heat disipation (aluminium heat sink, cooper heat pipes, breathable membrane...) for better performance of CREE XBD chips and Meanwell drivers.

The Multifunction 100 Series Floodlight is suitable for Advertising Light, Tunnel Light, High Bay or Spotlight. Great performance in units from 60W till 216W LED power and optional beam angles of 15º, 25º, 40º, 60º, 90º and 120º.

Series 100 of Sealed High Bays provide an excellent solution for ambiences where you need to keep the light source away of the air surrounding it.


The elegant finish makes it really suitable for a wide range of applications, from commercial till office buildings and convention centers, besides the industrial ones. Epistar a CREE versions available.
