Detailed description of the invention

Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.

The LED desk lamp 100 with air-cleaning function of first embodiment of the invention, please refer to Fig. 1 to Fig. 2.

A kind of LED desk lamp 100 with air-cleaning function, comprises lamp socket 20, lamp bracket 30 and lampshade 40, and this lampshade 40 is arranged on above this lamp socket 20, and this lamp bracket 30 connects this lamp socket 20 and this lampshade 40.Also comprise clean air package 10, this clean air package 10 comprises air inlet 12, purifying part 11 and air outlet 13, and air enters from this air inlet 12, discharges after the purification of purifying part 11 from air outlet 13.Please refer to Fig. 2, the LED light source (not shown) that this purifying part 11 includes photocatalyst layer 114 and irradiates towards this photocatalyst layer 114, this LED light source sends ultraviolet, and this photocatalyst layer 114 has the free radical of oxidisability to purify air for generation under the irradiation of this LED light source.

Wherein, preferably, this LED light source is arranged on the substrate of a hollow out, makes air can by the substrate of this hollow out, unobstructed to ensure air flowing.Also ensure that photocatalyst layer 114 can be subject to sufficient irradiation simultaneously, and produce enough free radicals.

By setting up clean air package 10 in light fixture, this LED desk lamp is made to have air-cleaning function, to meet consumer to the demand purified air.Meanwhile, optimize the LED light source having additional photocatalyst layer 114 in purifying part 11 and irradiate towards this photocatalyst layer 114 further, and this LED light source sends ultraviolet.Use Ultraviolet radiation photocatalyst layer 114, make to produce the free radical with oxidisability in air, this free radical may be used for degrading bacterium in air or organic matter.Clean air package 10 is made to have better air purification effect.

Please refer to Fig. 2, also comprise blower fan 116, this blower fan 116 is arranged near this air outlet 13, and this blower fan 116 drives air to enter and through purifying part 11 from air inlet 12, and drives the air after purification to discharge from air outlet 13.This blower fan 116 is connected by airduct 117 with this purifying part 11.

By arranging blower fan 116, drawing more air and entering in this clean air package 10 and purify, simultaneously by the air venting after cleaned in the external world.If do not arrange blower fan 116, the air entering into clean air package 10 reduces greatly, and air is owing to being subject to the drag effects of clean air package 10 simultaneously, is difficult to the air venting after by purification in the external world.

This purifying part 11 is arranged in this lamp socket 20, and this air inlet 12 is arranged on the sidewall of this lamp socket 20, and this air outlet 13 arranges on this lamp bracket 30, is connected between this air outlet 13 with this purifying part 11 by airduct 117.This purifying part 11 is provided with coarse filtration layer 111, HEPA filter course 112, active carbon filtering layer 113, photocatalyst layer 114 and anion generator 115 successively.

This purifying part 11 be arranged in lamp socket 20, LED desk lamp 100 compact overall structure making this have air-cleaning function, meets the demand of consumer to outward appearance.Coarse filtration layer 111, HEPA filter course 112, active carbon filtering layer 113, photocatalyst layer 114 and anion generator 115 are set in this purification portion.Coarse filtration layer 111 is for filtering out most bulky grain dust in air; HEPA filter course 112 is for filtering out the particle dust in air; Active carbon filtering layer 113 can peculiar smell, smog and organic matter etc. in absorbed air; Photocatalyst layer 114, through the irradiation of LED ultraviolet source, there occurs photocatalysis, produces the free radical of extremely strong oxidisability in the air near photocatalyst, and these free radicals can be degraded bacterium in air and organic matter further; Anion generator 115, for generation of anion, anion mixes with the air after above-mentioned purification, for the external world provides higher-quality air.

The one side of this coarse filtration layer 111 is air intake place, and air enters from coarse filtration layer 111.This coarse filtration layer 111 is placed along the direction of this lamp bracket 30, and this coarse filtration layer 111 is close to this air inlet 12 and is arranged, and this blower fan 116 is close to this air outlet 13 and is arranged.Also comprising every wind part, for being coated on side or the end face of purifying part 11, air being entered from the one side of coarse filtration layer 111.By arranging every wind part, staying air inlet 12 to be in communication with the outside, air being entered in clean air package 10 by air inlet 12, and can not be entered in clean air package 10 by other place.Therefore, air enters after in clean air package 10, can successively through coarse filtration layer 111, HEPA filter course 112, active carbon filtering layer 113, photocatalyst layer 114 and anion generator 115.Ensure that the air entered all can be cleaned.

This photocatalyst layer 114 produces the free radical with oxidisability in the irradiation air in its vicinity of LED light source, and described free radical is for bacterium in air or the organic matter of degrading.This LED light source sends the ultraviolet that wavelength is 300-400nm.

The LED desk lamp 100 with air-cleaning function of second embodiment of the invention, please refer to Fig. 3.

The difference of the second embodiment and the first embodiment is:

This clean air package 10 is arranged in this lamp bracket 30.This lamp bracket 30 is vertically arranged, and this purifying part 11 is vertically arranged along this lamp bracket 30, and this air inlet 12 is arranged on the rear side of this lamp bracket 30, and this air outlet 13 is arranged on the front side of this lamp bracket 30.Further simplify the structure of desk lamp, make overall structure compacter, attractive in appearance.

In sum, this LED desk lamp 100 with air-cleaning function, by setting up clean air package 10 in light fixture, makes this LED desk lamp have air-cleaning function function, to satisfy the demands of consumers.Meanwhile, the filter increasing photocatalyst layer 114 and the LED light source irradiated towards this photocatalyst layer 114, and this LED light source sends ultraviolet.Use Ultraviolet radiation photocatalyst layer 114, make to produce the free radical with oxidisability in air, this free radical may be used for degrading bacterium in air or organic matter.Clean air package 10 is made to have better air purification effect.Be arranged on by clean air package 10 in lamp socket 20 or in lamp bracket 30, whole light fixture is had, and compact conformation is attractive in appearance, structure simple, the advantage of good purification.

Understandable, when clean air package 10 is arranged in lamp socket 20, coarse filtration layer 111, HEPA filter course 112, active carbon filtering layer 113 and photocatalyst layer 114.Can horizontal positioned or vertically place as required.Arrange the setting of demand and miscellaneous part according to concrete lamp socket 20 space and determine.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
