Abstract
The utility model is a structure of high lightness flat lamp. The structure of high lightness flat lamp comprises a reflective plate, several ultraviolet light sources, a polymer layer and a phosphor layer. It is characterized in that the ultraviolet light resource and the polymer layer are clamped between the reflective plate and the phosphor layer. Ultraviolet light originated from the ultraviolet light resource and reflected by the reflective plate excites the phosphor layer to produce visible light using diffusion and photoconductivity performance of the polymer layer. Besides, it is reasonable to mix the polymer layer and the phosphor layer together to be one layer to make the ultraviolet light originated from the ultraviolet light resource and reflected by the reflective plate radiate directly to produce visible light.
Description
Technical field
The present invention relates to a kind of plane lamp, the colour temperature that particularly a kind of suitable structures is simple, processing procedure is easy evenly and the plane modulated structure of high brightness.
Background technology
The structure of previous cold-cathode fluorescent plant lamp (CCFFL) be utilize several within it wall be coated with the ultraviolet lamp tube of fluorescent material, imposes forceful electric power at its electrode place and press forming ultraviolet light, and bump fluorescent material is to form visible light.As No. 495796 " cold-cathode fluorescent plant lamp " described cold-cathode fluorescent plant lamp of Taiwan patent announcement, be after a cavity is vacuumized, inject blunt gas and mercury vapour, and between its negative electrode and anode, impose high voltage by a circuit board, make it to produce ultraviolet light, and impact the fluorescent material coating of coating its cavity inner wall, make it to produce visible light.Yet, seriously have influence on luminous efficiency because organic solvent residue after permanent the use, can produce burned black situation on the inner tubal wall at cold-cathode fluorescent plant lamp electrode place.
Summary of the invention
Main purpose of the present utility model provides the high brightness plane modulated structure that a fluorescent material is coated on the ultraviolet tube outside, can avoid traditional cold-cathode fluorescent plant lamp after long-term the use, and the electrode place can take place burned black and influence the shortcoming of luminous efficiency.
Secondary objective of the present utility model provides the high brightness plane modulated structure that an elasticity is placed ultraviolet source, can adjust the brightness of plane lamp.
Above-mentioned purpose of the present invention is achieved in that a kind of high brightness plane modulated structure, has reflecting plate, a plurality of ultraviolet source, high polymer layer and phosphor powder layer.Ultraviolet source and high polymer layer are folded between reflecting plate and the phosphor powder layer, and utilize the diffusion and the photoconduction performance of high polymer layer, make emission from ultraviolet source and via the ultraviolet light of baffle reflection, the fluorescence excitation bisque also sends the visible light of high brightness.In addition, more high molecular polymer and fluorescent material can be mixed into a high molecular polymer and phosphor powder layer, allow emission shine to send visible light from ultraviolet source and via the ultraviolet light of baffle reflection is direct.Ultraviolet source can be positioned in high polymer layer or high molecular polymer and the phosphor powder layer fully to reach maximum luminosity, also its part can be positioned over simultaneously and control its luminosity in the reflecting plate.

Description of reference numerals: 10 ultraviolet sources; 101 ultraviolet light first half light sources; 102 ultraviolet light Lower Half light sources; 11 reflecting plates; 12 high polymer layers; 13 phosphor powder layers; 20 ultraviolet sources; 201 ultraviolet light first half light sources; 202 ultraviolet light Lower Half light sources; 21 reflecting plates; 22 high molecular polymers and fluorescent material mixed layer.
Embodiment
Please refer to Fig. 1 a, Fig. 1 a is the stereogram of the utility model first embodiment.The bottom of lamp socket (not shown) is a reflecting plate 11, its be one can the uv reflectance wavelength reflecting plate.Be placed with several ultraviolet sources 10 on its reflecting plate 11, ultraviolet source 10 can be ultraviolet tube or ultraviolet light-emitting diodes.After its positive and negative electrode (figure does not show) applies voltage, around it, send ultraviolet light, and have the diffusion and the high polymer layer 12 of photoconduction function via coating its outside, with the uniform directive of ultraviolet light coat high polymer layer 12 on phosphor powder layer 13 and reflecting plate 11.Therefore, the ultraviolet light bump that phosphor powder layer 13 directly sends via ultraviolet source 10 on the one hand, in addition on the one hand via the ultraviolet light bump that is reflected by reflecting plate 11, and the plane visible light source of generation high brightness.
Please refer to Fig. 1 b, Fig. 1 b is the stereogram of the utility model second embodiment.Compared to first embodiment, the difference of second embodiment is that the some of its ultraviolet source 10 imbeds in the groove (not shown) of reflecting plate 11, therefore the ultraviolet light that is sent by the ultraviolet light Lower Half light source 101 that is embedded in reflecting plate 11 grooves is blocked by groove, so the ultraviolet light that only has ultraviolet light first half light source 102 to be sent will directly or via reflecting plate 11 clash into phosphor powder layer 13 indirectly.Therefore imbed the degree of depth in reflecting plate 11 grooves by adjusting ultraviolet source 10, can determine the brightness of plane visible light that lamp sends.
Please refer to Fig. 2 a, Fig. 2 a is the stereogram of the utility model the 3rd embodiment.Compared to first embodiment, the difference of the 3rd embodiment is high molecular polymer and fluorescent material are mixed.The ultraviolet light that is sent by ultraviolet source 20 and via the ultraviolet light bump high molecular polymer of reflecting plate 21 reflections and the fluorescent material in the fluorescent material mixed layer 22, and send visible light.And this visible light is able to via having the diffusion and the high molecular polymer of photoconduction effect in high molecular polymer and the fluorescent material mixed layer 22, outwards sends colour temperature evenly and the visible light of high brightness.
Please refer to Fig. 2 b, Fig. 2 b is the stereogram for the utility model the 4th embodiment.Compared to the 3rd embodiment, the difference of the 4th embodiment is ultraviolet light Lower Half light source 202 is imbedded in the groove (not shown) of reflecting plate 21.As second embodiment, the ultraviolet light that only has ultraviolet light first half light source 202 to be sent will directly or clash into fluorescent material indirectly via reflecting plate 21 and send visible light.Therefore imbed the degree of depth in reflecting plate 21 grooves by adjusting ultraviolet source 20, can determine the brightness of plane visible light that lamp sends.
Hence one can see that, the utility model is different from the structure that traditional cold-cathode fluorescent plant lamp is coated fluorescent material tube inner wall, and change fluorescent material is coated the outside of ultraviolet light source, and then exempt traditional cold-cathode fluorescent plant lamp and used the tube wall at its electrode of a specified duration can form burned black shortcoming, also promoted luminous efficiency simultaneously.In addition, utilize control to bury ultraviolet source underground the degree of depth, also reach simultaneously and adjust the brightness that the plane lamp sends visible light into reflecting plate.
Though the utility model in conjunction with preferred embodiment by description and interpretation especially, those skilled in the art will be appreciated that, can not deviate under spirit of the present utility model and the category, carry out reaching on the various forms change on the details.
