State the concrete meaning of term in the present invention.
Other features and advantages of the present invention will illustrate in subsequent specification, also, partly become from specification
It is clear that or understood by implementing the embodiment of the present invention.The purpose of the present invention and other advantages can be by being write
Specifically noted structure is realized and obtained in specification, claims and accompanying drawing.
To achieve the above object, the present invention provides following technical scheme：
In the present embodiment, as shown in Figure 1-2, Fig. 1 is a kind of the vertical of multi color temperature flexible LED lamp silk that the embodiment of the present invention one provides
To profile；Fig. 2 is a kind of transverse cross-sectional view of multi color temperature flexible LED lamp silk provided in an embodiment of the present invention.Multi color temperature LED is soft
Filament 1, including light-emitting device, the light-emitting device include the resistant to elevated temperatures substrate 101 that double-surface screen printing has circuit, and substrate thickness is
0.5-1.2mm, soft texture, it can fold, changes shape；Tow sides are provided with multiple flip LED cores on the substrate 101
Piece, such as the first flip LED chips 102 and the second flip LED chips 103, flip LED chips 102 and 103 are directly bound online
On base board, HVLEDs is connected into；The outside cladding external sealant of the light-emitting device, external sealant can rapid shaping using high temperature resistant
Heat conductive silica gel be made, and fluorescent material is mixed with external sealant, the ratio of mixed fluorescent powder is different in tow sides external sealant；Institute
State light-emitting device tow sides circuit can realize be separately energized and while be powered three kinds be powered combine, by controlling two sides to connect
HVLEDs size of current, different brightness combinations is realized, multiple color temperatures regulation can be achieved after coordinating with external sealant fluorescent material
Function.
In the preferred embodiment of the invention, more specifically, as shown in figure 1, the outside of the first flip LED chips 102 coats
First external sealant 104, the outside of the second flip LED chips 103 the second external sealant 105 of cladding, external sealant 104 and 105 use resistance to height
Temperature can the heat conductive silica gel of rapid shaping be made, and fluorescent material is all mixed with first, second external sealant 104 and 105, but first,
The ratio of mixed fluorescent powder is different in two external sealants 104 and 105, it will be understood that, such as：Mixed in first external sealant 104
The fluorescent material ratio of conjunction is（It is red：Yellow green=2:1）, the fluorescent material ratio of mixing is in the second external sealant 105（It is red：It is yellowish green
Color=3:5）, so can be achieved to be somebody's turn to do by adjusting the colour temperature of the external sealant 105 of the first external sealant 104 and second respectively
The adjustable LED filament 1 of multi color temperature shows multiple color.Specifically, the first flip LED chips 102 pass through first on substrate
The series connection of silk-screen circuit 106 forms the first HVLEDs, and the second flip LED chips 103 are gone here and there by the second silk-screen circuit 107 on substrate
Connection formed the 2nd HVLEDs, the first, second silk-screen circuit 106 and 107 can realize be separately energized and while be powered three kinds lead to
Electricity combination, by controlling the first and second HVLEDs size of current, different brightness combinations is realized, is matched somebody with somebody with external sealant fluorescent material
The function of multiple color temperatures regulation can be achieved after conjunction.For example, by controlling in the first silk-screen circuit 106 and the second silk-screen circuit 107
First HVLEDs colour temperature regulation is arrived 2000K by the electric current flowed through, and the 2nd HVLEDs colour temperature regulation is arrived into 5000K, so may be used
To show a kind of color；On the other hand, again by control the first silk-screen circuit 106 and the second silk-screen circuit 107 in flow through
Electric current, 4000K arrive into the regulation of the first HVLEDs colour temperature, the 2nd HVLEDs colour temperature is increased into 6000K, then and can be in
Reveal another color.The silk-screen circuit connection power module of the tow sides, and flowed through by power module control
The size of current of the silk-screen circuit of the tow sides.
In addition, multiple color temperatures regulatory function can also be accomplished by the following way in the present invention：
Mode one：The ratio of mixed fluorescent powder is different in first, second external sealant 104 and 105, in the first and second HVLEDs
The size of current passed through is the same, by controlling the change of the same current size, different brightness combinations is realized, with external sealant
The function of multiple color temperatures regulation can be achieved after fluorescent material coordinates in 104 and 105.
Mode two, the silk-screen circuit by tow sides connect to form the first HVLEDs and the 2nd HVLEDs respectively
In, the series connection replaces with the mode that in parallel or connection in series-parallel is combined.
Preferably, the first flip LED chips of the multiple connection are the chip or different colors of identical illuminant colour
Chip, the second flip LED chips of the multiple connection are the chip of identical illuminant colour or the chip of different colors.
Preferably, the first external sealant 180 degree coats the first HVLEDs and the substrate, second external sealant
180 degree coats the substrate and the 2nd HVLEDs.
In the preferred embodiment of the invention two, because substrate 101 uses relatively thin exotic material to be made, quality is soft
It is soft, while cladding external sealant 104 and 105 on the outside of light-emitting device, the external sealant 104 and 105 is by resistant to elevated temperatures heat conductive silica gel system
Into external sealant 104 and 105 itself has good pliability, therefore filament is very soft, can arbitrarily fold and changes shape；Substrate
101 tow sides all silk-screens have circuit, and tow sides are designed with flip LED chips 102 and 103, and circuit is all that silk thread is formed,
With foldability, although flip LED chips can not fold, because its size is smaller, therefore can't influence whole luminous
The folding property of device；Therefore, LED filament of the invention can form filament of different shapes by folding, and can meet client's
Various demands, also adapt to the shape of various light fixtures.The thickness of the substrate 1 is 0.5-1.2mm.The LED of the adjustable color is soft
The diameter of filament 1 could be arranged to 0.5mm-4mm, and length can be more than 10mm, and shape can arbitrarily be bent.
Preferably, the substrate 101 can be transparent flexible base board, or the flexible base board of coloured high printing opacity,
Its material can be polyimides, because it has good mechanical performance, very high radiation-resistant property and dielectric properties etc.,
In addition, the substrate 101 can also be made up of other flexible materials or hard material.
Preferably, the ring containing various concentrations fluorescent material can be mixed with first, second external sealant 104 and 105
Oxygen tree fat or silica gel or silicon gum.
In the preferred embodiment of the invention three, as shown in figure 3, being multi color temperature flexible LED lamp provided in an embodiment of the present invention
The electrical control of silk, the power module include adjustable driving power 201, the first switch of exportable two-way current adjustment
202 and second switch 203；The two-way delivery outlet of the adjustable driving power 201 passes through first switch 202 and second switch respectively
203 are connected to the silk-screen circuit of the first HVLEDs 204 and the 2nd HVLEDs 205.By controlling first switch 202 and
The shut-off of the i.e. controllable electric current by the first HVLEDs 204 and the 2nd HVLEDs 205 of shut-off of two switches 203, by can
It is the adjustable size of current for flowing through the first HVLEDs 204 and the 2nd HVLEDs 205 to adjust driving power 201, therefore, by this
Power module can realize the different brightness combinations of HVLEDs, and the work(of multiple color temperatures regulation can be achieved after coordinating with external sealant fluorescent material
Energy.
