Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and embodiments.
The scheme relates to a safe sterilizing and formaldehyde-removing LED lighting device, which is provided with an LED light source as shown in figures 1-3, wherein the LED light source comprises a white light LED module 2 and an UV-LED module 3, and the UV-LED module 3 comprises an UV-C LED module 31 and an UV-A LED module 32.
The wavelength range of the UV-C LED module 31 is 250-280nm, the wavelength range of the UV-A LED module 32 is 315-400nm, and the visible light wavelength range of the white light LED module 2 is 380-780 nm. As shown in fig. 4, the spectrum of the LED light source in the full bright mode has at least four spectral peaks corresponding to the LED modules.
The irradiation area of the UV-LED module 3 is internally provided with a nano titanium dioxide film 4. Preferably, the nano titanium dioxide film 4 is arranged at a close distance position with the irradiation distance of 10-500mm of the UV-LED module 3. In the embodiment shown, the UV-C LED module 31 and the UV-a LED module 32 of the UV-LED module 3 are mixedly arranged on the same circuit board, and the nano titanium dioxide film 4 is disposed at a short distance of 10-500mm directly in front of the circuit board, and further preferably at a short distance of 50-150mm directly in front of the circuit board.
According to the invention, as the UV-LED module 3 (comprising the UV-C LED module 31 and the UV-A LED module 32) and the white light LED module 2 are adopted, three functions of sterilization, formaldehyde removal and illumination can be realized on the same LED illumination device. The UV-LED module 3 and the nano titanium dioxide film 4 are matched to perform proper close irradiation, so that the photocatalytic effect of the nano titanium dioxide is effectively improved, formaldehyde components are effectively degraded, and excellent sterilization and formaldehyde removal effects are brought. The wave bands generated by the UV-C LED module 31 and the UV-A LED module 32 can catalyze the titanium dioxide film to enable the titanium dioxide film to have an adsorption function on formaldehyde, so that the LED lighting device has a reliable light sterilization function, wherein the energy provided by the UV-C is greatly higher than the forbidden bandwidth of the titanium dioxide, and the photocatalysis and formaldehyde removal effects of the titanium dioxide can be promoted to a certain extent.
The spectrum generated by the UV-A LED module 32 is converged with the white light generated by the white light LED module 2, and the near ultraviolet band (380 plus 400nm) of the UV-A LED module 32 constitutes a compensation spectrum for performing color rendering compensation on the white light generated by the white light LED module 2, i.e. the near ultraviolet band (380 plus 400nm) of the UV-A LED module 32 performs compensation for improving the color rendering quality of the whole white light spectrum on the white light generated by the white light LED module 2. Specifically, as shown in fig. 5-6, the 380-400nm portion of the right side of the peak of the spectrum generated by the UV-a LED module 32 falls within the near-ultraviolet band of visible light (e.g., the thick line portion in fig. 6), which has the function of compensating the spectrum for improving the white light generated by the conventional white LED module 2, and can effectively improve the spectra corresponding to R7 (munsell color scale 2.5P6/8) and R8 (munsell color scale 10P6/8) in the color rendering index Ri.
The light source color rendering index CRI has 15 colors and is represented by R1 to R15, wherein the average value of the color rendering indexes of the first 8 common colors is generally taken and is recorded as Ra to represent the color rendering of the light source. The seventh R7 represents light purple blue, the eighth R8 represents light red purple, and R7 and R8 both contain partial purple light spectrums, so that the invention skillfully utilizes the spectrum of the visible light falling on the right side of the UV-A, so that the values of R7 and R8 are improved, the quality (Ra) of the whole white light spectrum is compensated, the whole white light spectrum is more continuous in a short wave range, the quality of the color rendering index and the light chromaticity quality of the illumination spectrum is improved, and the illumination effect of the LED illumination device is improved.
Further, the LED lighting device of the present invention further comprises a housing 1, wherein the housing 1 has a module slot, the module slot has a slot 10, a bottom region 11 opposite to the slot 10 is disposed in the module slot, and two opposite side regions (a first side region 12 and a second side region 13) are disposed in the module slot.
The white light LED module 2 is installed at the bottom position 11, in an embodiment, a first card slot 111 is disposed at the bottom position 11 of the module slot, and the circuit board of the white light LED module 2 is correspondingly installed on the first card slot 111. The back of the module slot corresponding to the white LED module 2 is preferably formed with a heat dissipation channel 15, so as to provide a good heat dissipation path for the white LED module 2. Heat dissipating fins 151 are also preferably disposed in the heat dissipating channel 15.
The UV-LED module 3 and the nano titanium dioxide film 4 are respectively arranged on the first side zone bit 12 and the second side zone bit 13. Specifically, the first side area 12 and the second side area 13 of the module slot are respectively provided with a second card slot 121 and a third card slot 131. The UV-LED module 3 and the nano titanium dioxide film 4 are respectively embedded and assembled on the second card slot 121 and the third card slot 131.
When the LED illuminating device is used, the white light for illumination provided by the white light LED module 2 is directly emitted from the notch 10, so that an excellent illuminating effect is realized. The UV-LED module 3 and the nano titanium dioxide film 4 are matched relatively in a close range to realize the functions of sterilization and formaldehyde removal, and meanwhile, because the UV-LED module 3 and the nano titanium dioxide film are positioned on the side, the light of the UV-LED module 3 cannot directly irradiate the eyes of people, and the damage to the human body cannot be caused in the use process; the compatible design of three functions of sterilization, formaldehyde removal and illumination on the LED illumination device is realized.
Preferably, referring to fig. 3, the housing 1 is installed in a manner that the notch 10 of the module groove faces obliquely downward, the first side zone 12 and the second side zone 13 are inclined and arranged up and down, wherein the nano-titanium dioxide film 4 is arranged on the first side zone 12 corresponding to the upper side zone, and the UV-LED module 3 is arranged on the second side zone 13 corresponding to the lower side zone. The inclined design is not only beneficial to effective illumination, but also can fully exert the sterilization and formaldehyde removal functions of the UV-LED module 3 and improve the safety by hidden design.
Preferably, the internal included angle between the white light LED module 3 at the bottom region 11 and the UV-LED module 3 at the second side region 13, and the internal included angle between the white light LED module 3 and the nano titanium dioxide thin film 4, may be 60-120 degrees; further preferably, the internal angle between the white light LED module 3 on the bottom region 11 and the UV-LED module 3 on the second side region 13 is 70-90 degrees, and the internal angle between the white light LED module 3 and the nano titanium dioxide thin film 4 is 90-110 degrees. Wherein, the sum of the internal included angles between the nano titanium dioxide film 4 and the UV-LED module 3 and the white light LED module 3 is preferably 180 degrees or slightly larger than 180 degrees, and the larger part of the slightly larger part of 180 degrees is preferably included in the internal included angle between the white light LED module 3 and the nano titanium dioxide film 4; for example, when the sum of the internal included angles is 190 degrees, the internal included angle between the white light LED module 3 at the bottom region 11 and the UV-LED module 3 at the second side region 13 is 90 degrees, and the internal included angle between the white light LED module 3 and the nano titanium dioxide thin film 4 is 100 degrees. The design of such angle is further favorable to LED lighting device to disinfect the formaldehyde-removing function and improve the security performance. Furthermore, the outer edge of the upper first side area 12 is extended outwards than the outer edge of the lower second side area 13, and the proper epitaxial design of the upper first side area 12 and the nano titanium dioxide thin film 4 forms an upper inclined type hood eaves, which is beneficial to the LED lighting device to play the functions of sterilization and formaldehyde removal and improve the safety performance.
