Abstract

An air purification apparatus and an illuminating apparatus which provide an eye protecting table lamp that emits gentle light and has an air purification function. The eye protecting table lamp comprises a lamp body unit, a lamp base unit, a focus lamp unit and an air purification unit. The focus lamp unit comprises an illuminant, a cambered reflecting mirror and a light collector. The illuminant has at least one environmentally protective and energy economized LED with minimal heat emission and a long service life. The cambered reflecting mirror is arranged at one side of the illuminant. The light collector is arranged at the side opposite to the reflecting mirror of the illuminant. The air purification unit comprises an air inlet, an extreme ultraviolet emitting device, an air exhaust device, a negative ion generating device and an air outlet.

Claims

1. An eye protecting table lamp having an air purification function, comprising:

a lamp body unit;

a lamp base unit;

a focus lamp unit; and

an air purification unit,

wherein the focus lamp unit comprises an illuminant having at least one environmentally protective and energy economized LED with minimal heat emission;

a curved reflecting mirror which is arranged at one side of the illuminant for uniformly reflecting light from the illuminant; and

a transparent light collector which is arranged at the side opposite to the reflecting mirror of the illuminant for causing the light from the illuminant to be emitted in a convergent manner,

wherein the air purification unit comprises an air inlet, an extreme ultraviolet emitting device, an air exhaust device, a negative ion generating device and an air outlet which are connected in this turn, and

wherein the negative ion generating device comprises a cathode high voltage fiber thread which is arranged in the air outlet.

2. The eye protecting table lamp having an air purification function according to claim 1, wherein the at least one LED is provided on a circuit board.

3. The eye protecting table lamp having an air purification function according to claim 1, wherein the upper end of the lamp body unit is coupled by a pivot to an end of the focus lamp unit, and the lower end of the lamp body unit is fixedly connected to the air purification unit whose lower end is fixedly connected to the lamp base unit.

4. The eye protecting table lamp having an air purification function according to claim 3, wherein the focus lamp is movably coupled to the lamp body unit by an articulated coupler, a flexible annular fixed guide and coupling shaft, wherein the articulated coupler is provided on the focus lamp unit and has gear teeth at its interior circumference, and the articulated coupler is provided at its exterior circumference wit one or more than one engaging teeth which are engaged with the gear teeth, the coupling shaft being provided at the upper end of the lamp body unit and being rotatably inserted into the articulated coupler together with the annular fixed guide.

5. The eye protecting table lamp having an air purification function according to claim 3, wherein the lamp base unit is provided with a switch for turning on or off the power of the focus lamp unit through contacting wit or release from the focus lamp unit.

6. The eye protecting table lamp having an air purification function according to claim 1, wherein the extreme ultraviolet emitting device comprises an air aggregation unit, an extreme ultraviolet radial tube arranged at the center of the air aggregation unit, an air aggregation wall for aggregating the air and making it flow through the extreme ultraviolet radial tube, a dust removal device arranged at the air inlet end of the air aggregation unit, and an air aggregation sash which is arranged at the air outlet end of the air aggregation unit for facilitating the entry of air and making the air arrive at the air outlet through the air aggregation unit.

7. The eye protecting table lamp having an air purification function according to claim 6, wherein shielding walls are provided respectively at the air inlet end and the air outlet end to prevent the ultraviolet which may hurt the user from radiating outward.

8. The eye protecting table lamp having an air purification function according to claim 1, wherein the extreme ultraviolet emitting device generates an extreme ultraviolet having a wavelength of 253 nm, and the output of the cathode high voltage generated by the negative ion generating device is 4.5-8.5 kv.
