Abstract

Purpose of the present invention is the realization of a LED illuminating device, more specifically a LED lamp structure with standard caps (Edison, bayonet.. ) and therefore ready to install on any existing lighting system, able to break down, thank you to its own technical and constructive characteristics, the microbial load present in the environments in which the luminaire is installed. The device also allows a power consumption not different from the one of a standard LED bulb/lamp, does not employ photocatalytic materials classified as hazardous, does not emit wavelengths that fall in the ultraviolet region but only in the band 405-420 nm, and can be supplied with a thermostated lighting room and an articulated endowment of sensors and management technologies.

Claims

AMENDED CLAIMS
received by the International Bureau on 19 October 2017 (19.10.2017)
1) A lamp structure for the reduction of the environmental bacterial count exerted through the microbicidal action produced by the controlled, managed, and monitored combination of light emitting diode (LED) sources, characterized by the presence of:
a circuit board (105) on which there are three set of LEDs (106, 107 and 108) and a sensor (123) connected to a microcontroller (121) as well as monitoring probes (125) and a wireless device (126) for remote control;
- a sensor (123) for detecting the heat emitted by the device, which parameters are processed by a microcontroller (121) that, once the temperature of the PN junction of the LEDs is calculated, adjusts the applied voltage on the Peltier cells (122) in order to increase or decrease the circuit board temperature so that the spectral properties of the LEDs remain constant ;
a photocatalytic material based on Titanium Dioxide (TI02), or other analogous material which exerts analogous biocidal and/or virucidal and/or allergenic control action. 2) A LED lamp structure for the reduction of the environmental bacterial count, as claimed in claim 1), characterized by the presence on the circuit board (105) of three set of LEDs (106, 107 and 108) in which:
- a first group of LEDs (106) is composed of a red LED (109) which is capable of emitting a visible electromagnetic radiation in the range between 633 and 660 nm, a green LED (110) which is capable of emitting a visible electromagnetic radiation in the range between 555 and 570 nm, a blue-violet LED (111) which is capable of emitting a visible electromagnetic radiation with a wavelength in the range between 405 and 410 nm, accompanied by a white LED (112) which is capable of emitting light with continuous spectrum of energy in a colour temperature that lays in the range between 1000 and 20000K;
- a second group of LEDs (107) is composed of a red LED (113) which is capable of emitting a visible electromagnetic radiation in the range between 633 and 660 nm, a green LED (114) which is capable of emitting a visible electromagnetic radiation in the range between 555 and 570 nm, a blue-violet LED (115) which is capable of emitting a visible electromagnetic
22 radiation with a wavelength in the range between 410 and 415 nm, accompanied by a white LED (116) which is capable of emitting light with continuous spectrum of energy in a colour temperature that lays in the range between 1000 and 20000K;
- a third group of LEDs (108) is composed of a red LED (117) which is capable of emitting a visible electromagnetic radiation in the range between 633 and 660 nm, a green LED (118) which is capable of emitting a visible electromagnetic radiation in the range between 555 and 570 nm, a blue-violet LED (119) which is capable of emitting a visible electromagnetic radiation with a wavelength in the range between 415 and 420 nm, accompanied by a white LED (120) which is capable of emitting light with continuous spectrum of energy in a colour temperature that lays in the range between 1000 and 20000K.
3 ) A LED lamp structure for the reduction of the environmental bacterial count, as claimed in 1) and 2), characterized by the presence of a photocatalytic material based on Titanium Dioxide (TI02) that is activated through the precise combination of the LEDs groups' wavelengths.
