LED device with sterilization, formaldehyde removal and illumination functions

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).

Problems solved by technology

[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 urgently: First, due to the influence of smog and rainy weather, people worry about the hygiene of underwear, and the current market The clothes disinfection cabinets sold are bulky and expensive, and are not suitable for ordinary households; second, because the furniture, especially the panels and paints of bedroom wardrobes, contain formaldehyde, and the release cycle of formaldehyde is as long as 5-10 years, people often use Civilian and convenient methods such as ventilation and plant absorption (such as tea) to purify the air in the home

However, the doors and windows of rooms and wardrobes need to be closed frequently, which greatly limits the application of ventilation method and plant absorption method
