According to the above LED surface light source, the red light emitted by the red light LED and the white light emitted by the plurality of white light LEDs are composited to form warm white light, light emitting color rendering indexes of light sources of the LED panel are improved, the structure is simple, manufacturing is convenient, and the cost is low.
Description
Technical field
The utility model relates to field of light fittings, particularly relates to a kind of LED area source.
Background technology
At present, base blue-ray LED is combined with yellow fluorescent powder, by the compound generation white light of light, produces thus white light LEDs, this white light LEDs lacks ruddiness, and color rendering index is lower.
In order to improve the color rendering of white light LEDs, can, time prepared by white light LEDs, in yellow fluorescent powder, mix red fluorescence powder, color rendering index can bring up to 85 from original 65.But traditional red fluorescence powder is mainly that sulfide host luminescent body is easily vaporized in air, poor chemical stability take sulfide as basis, and brightness is low, in application, is very restricted.Along with scientific and technological development, there is in the world the light-converting material that some are novel---Sr2SiO4:Eu2+ and Sr3SiO5:Eu2+, this material has more excellent temperature characterisitic, after overdoping Ba2+, the color rendering index 85 that it is launched under blue-light excited, colour temperature reaches 2500～5000K, becomes a kind of good warm white light, but because its stability is inadequate, cost is higher, not yet form commercial application.
Utility model content
Based on this, be necessary to manufacture the problem difficult, cost is higher for traditional white light LEDs that white light LEDs color rendering index is lower and color rendering index is higher, a kind of LED area source simple, cost is lower, color rendering index is higher of manufacturing is provided.
A kind of LED area source, comprise flexible circuit board, at least one red-light LED and multiple white light LEDs, described flexible circuit board has multiple grooves that are parabolic shape, wherein, have at least a groove to be surrounded by other grooves, in described groove, have aln layer, described red-light LED is installed in besieged groove, described multiple white light LEDs is installed in other grooves, and described red-light LED is electrically connected with the circuit of described flexible circuit board by gold thread with white light LEDs.
In an embodiment, the top of described red-light LED and white light LEDs is coated with layer of silica gel therein, and described layer of silica gel raises up.
In an embodiment, the surface of described flexible circuit board is provided with lens therein, described lens by described red-light LED and white-light LED encapsulation in described groove.
In an embodiment, described multiple white light LEDs are connected in series therein.
In an embodiment, described red-light LED and described multiple white light LEDs are connected in series therein.
In an embodiment, described flexible circuit board comprises metal substrate, composite layer and Copper Foil therein, and described composite layer is coated on described metal substrate, and described Copper Foil is mounted on described composite layer.
