Device for increasing the useful life and reducing energy consumption by individual dimming in LED lamps
Summary:
Innovative Spanish company develops a driver or power supply for voltage conditioning in intelligent LED lamps, capable of supplying any model of luminaire with the exact value of voltage and intensity that optimizes the useful life of it. The system can be useful for public lighting systems, intensive animal farming or intensive agriculture lighting. The company is interested in licensing agreements with manufacturers or technological intermediaries.
Description:
The Spanish company with experience in the field of lighting system, was established in 2012 and operates from the Canary Islands. The company has a solid background in visible light communications technology (VLC). The company works in the field of the telecommunication, home automation and optoelectronics. It was beneficiary of H2020 SME instrument phase 1 and phase 2, and is involved in international cooperation.project.

The SME has developed a solution that solves common problems in the LED lighting sector, it conveniently regulates the operating temperature of the LED.

In the systems present on the market, said regulation is obtained by the inclusion of a heatsink in the power supply that is capable of adapting to the different models of LEDs on the market. The solution offered improves heat dissipation by being able to adapt to the specific lamp that is powered by a programmable smart unit.

The level of luminous intensity of an LED depends on the intensity of the current passing through it, the system developed a more efficient method of controlling it. A simpler system that relies on the integration property of the human eye, which is not able to distinguish very fast changes in the captured images. The mechanism for LED lamps that requires a signal frequency higher than 50 Hz to see that the light never flickers.

Another problem of the lamps is related to the dissipation of the heat generated and the temperature reached by the electronic devices that can stop their operation temporarily or permanently. For this reason, the system introduces heat sinks and heat-conducting elements that facilitate the evacuation of the heat generated.

The new LED lamps introduce several advantages, such as longer life and lower consumption, or the possibility of easily generating different colours. It is necessary to introduce or develop specific methods to provide these LED lamps with functionality similar to that provided by conventional lamps.
The device designed can be used in all those lighting systems based on LED lamps to set different lighting level values and/or reduce the effects of heat and temperature in these devices.

Some applications can be:
1. Control of lighting in tunnels can design and implement curve brightness variation along the tunnel according to environmental conditions and comfort and safety for the driver.
2. Control of lighting in shopping centres, can set the desired light intensity in each fixture equipped with this system.
3. Lighting and street signs as well as homes for energy savings and comfort.
4. Vehicle Headlights, so that a single lamp can replace all or more of those used currently changing its level of illumination.
For example, the same lamp with low intensity LED function as running lights and with greater intensity could replace the position and cross, could even replace long or fog lights.

The company is looking for licensing the patent exploitation to a manufacturer of power supplies for LED lamps with capacity or sales agreements for the supply of large quantities of LED luminaires for public lighting systems or systems where the regulation of lighting must be developed at frequencies above 50Hz (in the case of intensive animal farming or intensive agriculture).

Advantages and Innovations:
ADVANTAGE
1. The offered system implies a reduction of manufacturing costs, as the power supply manufacturer only needs to develop a single hardware.
2. The offered device allows individual dimming of each luminaire to the required value, reducing energy consumption by up to an additional 50%.
3. The device enables smart grid management or remote dimming directly via its intelligence unit or data transmission via the LED light beam.
INNOVATIONS
1. This device provides a method and system for controlling the illumination of LED lamps capable of extending the life of LED lamps.
2. The device developed is able to reduce the maximum temperatures reached by LED lamps without generating flicker or any alteration in the lighting generated.
3. This device also provides a system able to select the resolution and bright illumination intensity of an LED lamp using the full capacity of the lamp´s light.
4. This model also provides a method and system for self-regulating the control lighting power and therefore able to power any type of LED lamp, regardless of its voltage-current characteristics and the required power supply.
