Embodiment Construction

[0041] The present case will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] This case involves an LED device with functions of sterilization, formaldehyde removal and lighting, such as Figure 1-3 As shown, there is an LED light source, and the LED light source includes a white LED module 2 and a UV-LED module 3 , and the UV-LED module 3 includes a UV-CLED module 31 and a UV-ALED module 32 .

[0043] The band 31 of the UV-CLED module is 250-280nm, the band 32 of the UV-ALED module is 315-400nm, and the visible light band of the band 2 of the white LED module is 380-780nm. Such as Figure 4 As shown in the spectrum diagram of the LED light source in full brightness mode, the LED light source has at least four spectral peaks corresponding to each LED module.

[0044] A nano titanium dioxide thin film 4 is provided in the irradiation area of ​​the UV-LED module 3 . Preferably, the nano-titanium dioxide thin...

Abstract

The invention discloses an LED device with sterilization, formaldehyde removal and illumination functions.An LED light source comprises an UV-LED module and a white LED module.The UV-LED module comprises UV-C LED modules and UV-A LED modules.A nanometer titanium dioxide thin film is arranged in the irradiation area of the UV-LED module.The wave band of the UV-C LED modules is 250-280 nm.The wave band of the UV-A LED modules is 315-400 nm.The visible light wave band of the white LED module ranges from 380 nm to 780 nm.The LED light source has at least four spectrum wave crests corresponding to the LED modules.A spectrum generated by the UV-A LED module intersects with white light generated by the white LED module.The near ultraviolet band of the UV-A LED modules forms a compensation spectrum used for conducting color development compensation on the white light generated by the white LED module.Because the three sterilization, formaldehyde removal and high-color-rendering-property illumination functions are integrated on the same LED device at the same time, the LED device can be widely applied to home wardrobes, cabinets and water heating sanitary products.

Description

technical field [0001] The invention belongs to the field of LED special lighting, and in particular relates to an LED device with functions of sterilization, formaldehyde removal and lighting. Background technique [0002] With the development of short-wavelength semiconductor light-emitting technology, ultraviolet LEDs have been gradually used in curing, sterilization, medical treatment, printing, biological detection, high-density information storage and secure communication applications, especially in ultraviolet light sterilization and ultraviolet photocatalysis. There is a huge space for development in this field, so it has become a current research hotspot. At present, ultraviolet rays can be divided into four bands: UV-A (400-315nm), UV-B (315-280nm), UV-C (280-200nm) and vacuum ultraviolet (200-100nm). [0003] At the same time, with the improvement of people's health awareness and quality of life, two practical problems in the current society need to be solved urg...
