Abstract
The invention discloses a fluorescent powder composition. The fluorescent powder composition comprises the following components in percentage by weight: 7-14% of (Sr, Ca, Ba)5(PO4)3Cl:Eu<2+>, 16-24% of (Ce, Tb)MgAl11O19, 30%-37% of Y2O3:Eu<3+>, and 35%-42% of 12(Sr, Eu)O.(B2O3).5P2O5. A fluorescent lamp manufactured from the fluorescent powder composition has the characteristics of being high in color rendering and high in photosynthetic efficiency. The invention further provides a fluorescent lamp which is manufactured from the fluorescent powder composition. The fluorescent lamp has the characteristics of being high in color rendering and high in photosynthetic efficiency.
Description
Technical field
The present invention relates to lighting technical field, be specifically related to a kind of containing fluorescent powder composition and reach the luminescent lamp by its making.
Background technology
Third generation lamp has energy-conservation and advantage long service life, has therefore obtained extensive utilization.The luminous source of third generation lamp is raw material mainly with rare-earth trichromatic fluorescent powder greatly.At present in order to improve the luminescent properties of lamp, be mainly that component by changing fluorescent material is adjusted photochromic, to improve the color developing of three-basic-colour lamp.Because the colour rendering index of three-basic-colour lamp is subject to the impact of the emission peak of blue powder significantly, so, when changing its emission peak and be 470～500nm (bluish-green powder), the color developing of three-basic-colour lamp can be significantly improved.Several bluish-green powder commonly used are as follows:
Some occasion illumination now needs to use high-color rendering and high-resolution light source.Current containing fluorescent powder composition can not meet the requirement of luminescent lamp high-color rendering and high light efficiency.
The content of invention
In order to solve one or more in the problem that prior art exists, the invention provides a kind of containing fluorescent powder composition, there are the characteristics of high-color rendering and high light efficiency with the luminescent lamp of its making.
Concrete solution is:
A kind of containing fluorescent powder composition, the component comprised and the weight percent of each component are:
Preferably, described (Sr, Ca, Ba)
5(PO

3) .5P
2o
5luminescence peak be 480nm.
Preferably, the weight percent of each component is:
The technique effect that a kind of containing fluorescent powder composition provided by the invention has is: the characteristics that have high-color rendering and high light efficiency with the luminescent lamp of its making.
The present invention also provides a kind of luminescent lamp, by described containing fluorescent powder composition, is made.This luminescent lamp has the characteristics of high-color rendering and high light efficiency.
Embodiment
After each component in following table is mixed by corresponding weight percent, stir and obtain containing fluorescent powder composition.
Table 1
| Component | Embodiment 1 | Embodiment 2 | Embodiment 3 |
| (Sr，Ca，Ba) 5（PO 4） 3Cl∶Eu 2+ | 14% | 7% | 12% |
| (Ce，Tb)Mg Al 11O 19 | 24% | 14% | 22% |
| Y 2O 3∶Eu 3+ | 30% | 37% | 35% |
| 12(Sr，Eu)O.(B 2O 3).5P 2O 5 | 32% | 42% | 31% |
The containing fluorescent powder composition that embodiment 1 forms can significantly strengthen color developing, and improves light efficiency.The containing fluorescent powder composition that embodiment 2 forms can significantly improve light efficiency, and strengthens color developing.The containing fluorescent powder composition that embodiment 3 forms is moderate universal optical matchmaker combination.
The present invention also provides a kind of luminescent lamp, by described containing fluorescent powder composition, is made.This luminescent lamp has the characteristics of high-color rendering and high light efficiency.
