Utility model content
the technical problems to be solved in the utility model is to provide a kind of all-weather light catalyst air purifying LED daylight lamp, effectively utilizes photo-catalytic sterilization principle, realizes 24 hours round-the-clock clean elimination harmful substances and purifies the air of a room.
For solving the problems of the technologies described above, the utility model relates to a kind of all-weather light catalyst air purifying LED daylight lamp, comprise lamp housing and the lamp plate being arranged at lamp housing inside, described lamp plate is arranged three row LED luminescence chips, wherein two rows are illumination LED luminescence chip, arrange row's sterilization LED luminescence chip between described two row's illumination LED luminescence chips; Described lamp housing outer surface is ground glass structure, described lamp housing outer surface titanium dioxide layer.
Preferably, the emission wavelength of described illumination LED luminescence chip is 465nm, the outer application yellow of described illumination LED luminescence chip and red fluorescence powder.465nm wavelength light excites yellow fluorescent powder and red fluorescence powder to improve colour rendering, to reach the object of illumination.
Preferably, the emission wavelength of described sterilization LED luminescence chip is 380nm.The ultra-violet light-emitting chip of 380nm wavelength, can excite the photocatalyst effect of titanium dioxide, produces strong catalytic degradation function; Effectively to degrade toxic and harmful in air; Effectively can kill various bacteria, and the toxin that bacterium or fungi can be discharged decomposes and harmless treatment; Also possesses the function such as deodorizing, anti-soil simultaneously.
Preferably, described lamp housing inside arranges driving power, and described driving power is electrically connected with LED luminescence chip.
Preferably, described illumination LED luminescence chip is in parallel with sterilization LED luminescence chip, and two parallel branches control respectively by independent switch.Utilize natural daylight to carry out photo-catalytic sterilization effect when daytime is sunny, when insufficient light or rainy weather, when not needing illumination, sterilization luminescence chip can be opened and carry out bactericidal action; Need night during illumination, double switch to be opened simultaneously, while illumination, carry out bactericidal action, do not need only to open sterilization LED luminescence chip during illumination, thus reach the object that whole day purifies air.
Preferably, the thickness of described titanium dioxide layer is 1.2mm ~ 2.5mm, and titanium dioxide layer is photocatalyst, and its thicker situation is conducive to the sterilizing function strengthening light fixture, but can be an impediment to ultraviolet light percent of pass; The situation that photocatalyst is thinner is conducive to the percent of pass improving ultraviolet light, but reduces the sterilizing function of photocatalyst.Therefore above-mentioned thickness range is a scope making that aforementioned two kinds of situations are comparatively balanced.
The beneficial effects of the utility model are: by lamp housing outer surface is designed to ground glass structure, on the one hand the direct projection light of LED are carried out refraction and allow light become soft, are convenient to titanium dioxide coating on the other hand and increase catalytic reaction effective active area; By increasing ultra-violet light-emitting chip in LED daylight lamp, carry out bactericidal action with the catalytic reaction of titanium dioxide generation light; 24 hours whole days are only eliminated harmful substance and are purified the air of a room, and greatly reduce the injury of indoor harmful substance to human body.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.
See Fig. 1, the utility model relates to a kind of all-weather light catalyst air purifying LED daylight lamp, comprise lamp housing 1 and the lamp plate 2 being arranged at lamp housing inside, lamp plate 2 is arranged three row LED luminescence chips, wherein two rows arrange between illumination LED luminescence chip 3 for illumination LED luminescence chip 3, two and arrange row's sterilization LED luminescence chip 4.Lamp housing 1 inside arranges driving power 5, and driving power 5 is electrically connected with LED luminescence chip.Lamp housing 1 outer surface is ground glass structure, titanium dioxide coating layer 6 on it.
The emission wavelength of illumination LED luminescence chip 3 is 465nm, can apply yellow and red fluorescence powder to increase colour rendering outside it.The emission wavelength of sterilization LED luminescence chip 4 is 380nm.The ultra-violet light-emitting chip of 380nm wavelength, can excite the photocatalyst effect of titanium dioxide, produces strong catalytic degradation function; Effectively to degrade toxic and harmful in air; Effectively can kill various bacteria, and the toxin that bacterium or fungi can be discharged decomposes and harmless treatment; Also possesses the function such as deodorizing, anti-soil simultaneously.
The general name with the semi-conducting material of photo-catalysis function of nano photo-catalytic to be a kind of with Nano titanium dioxide be representative, adopts titanium dioxide (TiO2) material in the present embodiment.It utilizes light source to do catalytic reaction, excitation electron after the energy of absorption ultraviolet (effective wavelength 380nm), produce electron-hole pair, and move to material surface rapidly, activate the harmful substance being adsorbed on material surface, by toxic organic compound oxidation Decomposition, can kill and suppress germ to regenerate and nitrogen, sulfur oxide in Cleaning Air.
See Fig. 2, anatase crystallization nano TiO 2 is a kind of photochemical catalyst, due to its semiconductor property, when being subject to the ultraviolet light (below 380nm) in sunshine or fluorescent light and irradiating, electronics in valence band is excited to conduction band, produces electronics (e-) at TiO2 atomic surface---positive hole (h+) effect.The electronics e-flown out combines with the oxygen in air, generates " O2-".The electronics positive hole h+ formed that flies out captures the electronics of water in air, is formed "-OH ".This due to electron transfer effect, " O2-" and "-OH " that produced has extremely strong oxidative decomposition capacity, make the formation stench that contacts with it and filthy oil content miscellaneous bacteria be harmful to gas, precursor virus, mould etc. to organise and thing decomposes innoxious, make NOX, SOX conversion is determined and innoxious.
