Referring to fig. 1, 2 and 3, the present embodiment provides a multi-color temperature lamp strip applied to a decorative lamp. The multicolor temperature lamp strip comprises a plurality of luminous sources, a strip-shaped substrate 300, a first multicolor temperature glue layer 400 and a second multicolor temperature glue layer 500. The plurality of light sources are disposed on the same side of the strip-shaped substrate 300 along the length direction of the strip-shaped substrate 300, and the plurality of light sources are disposed in two rows along the width direction of the strip-shaped substrate 300. The first color temperature adhesive layer 400 covers one of the two rows of the plurality of light sources along the length direction of the strip substrate 300, and the first color temperature adhesive layer 400 is used for converting the light emitted by the row of light sources into light with a first color temperature.

The embodiment of the application provides a polychrome temperature lamp area, because one row in two rows of a plurality of light emitting sources covers has first colour temperature glue film 400, and another row in two rows of a plurality of light emitting sources covers has second colour temperature glue film 500, when needs make polychrome temperature lamp area send the light of first colour temperature, accessible light and the corresponding one row of light emitting source of first colour temperature glue film 400 of lightening for the light that the light emitting source sent turns into the light of first colour temperature through first colour temperature glue film 400. When the light of second colour temperature is sent in needs messenger's polychrome temperature lamp area, the accessible lights a row of light emitting source corresponding with second colour temperature glue film 500 for the light that the light emitting source sent passes through second colour temperature glue film 500 and turns into the light of second colour temperature, thereby makes this polychrome temperature lamp area can send the light of two kinds of colour temperatures. Wherein, because this first color temperature glue film 400 and second color temperature glue film 500 set up side by side, separately glue, mutual noninterference for the colour temperature of this polychrome temperature lamp area is more concentrated, the color tolerance is little, so the yields promotes by a wide margin. Meanwhile, the first color temperature adhesive layer 400 and the second color temperature adhesive layer 500 are thin in colloid, so that the cost can be saved.
Among them, the strip substrate 300 may be an FPC substrate (a flexible printed circuit board made of polyimide or polyester film as a base material having high reliability and excellent).
The first color temperature adhesive layer 400 and the second color temperature adhesive layer 500 can be silica gel, and the light emitting color of the multicolor temperature lamp strip can be adjusted by fluorescent powder mixed in the silica gel.
As shown in fig. 3, in the above embodiment, optionally, the cross-sectional shape of the first color temperature adhesive layer 400 and/or the second color temperature adhesive layer 500 is arc-shaped.
Specifically, the arc-shaped first color temperature adhesive layer 400 and/or the arc-shaped second color temperature adhesive layer 500 are equivalent to convex lenses, and can disperse light emitted by the first light emitting diode 100 and/or the second light emitting diode 200 serving as a point light source, thereby avoiding generation of light spots and improving the light extraction effect.
Example two
As shown in fig. 1, the present embodiment proposes an arrangement manner of the first conductive layer 320 based on the first embodiment. One of the two rows of the plurality of light emitting sources is a plurality of first light emitting diodes 100, the other of the two rows of the plurality of light emitting sources is a plurality of second light emitting diodes 200, one side of the strip-shaped substrate 300 provided with the plurality of light emitting sources is a front surface 310, a first conductive layer 320 is arranged on the front surface 310, the first conductive layer 320 is patterned into a first electrode 321 and a second electrode 322, the first electrode 321 and the second electrode 322 are respectively positioned on two sides of the strip-shaped substrate 300, the plurality of first light emitting diodes 100 and the plurality of second light emitting diodes 200 are respectively connected in series between the first electrode 321 and the second electrode 322, and the electrode directions of the first light emitting diodes 100 and the second light emitting diodes 200 in a circuit between the first electrode 321 and the second electrode 322 are opposite.
Specifically, since the first and second light emitting diodes 100 and 200 have opposite electrode directions in the circuit between the first and second electrodes 321 and 322 and have unidirectional conductivity, when the first electrode 321 is a positive electrode and the second electrode 322 is a negative electrode, a current can pass through the plurality of first light emitting diodes 100, thereby lighting only the first light emitting diodes 100. When the first electrode 321 is a negative electrode and the second electrode 322 is a positive electrode, a current can pass through the plurality of second light emitting diodes 200, and only the second light emitting diodes 200 can be turned on. Therefore, the direction of the current between the first electrode 321 and the second electrode 322 can be changed to control the corresponding light emitting diode to emit light. Because the circuit arrangement mode only needs to arrange the first electrode 321 and the second electrode 322, the width of the strip-shaped substrate 300 can be further shortened, and the multicolor temperature lamp strip can be applied to some narrower installation environments.
As shown in fig. 1, in the above embodiment, optionally, the first conductive layer 320 is further patterned with a plurality of first conductive lines 323 and a plurality of second conductive lines 324, one first conductive line 323 is conducted between two adjacent first light emitting diodes 100, one second conductive line 324 is conducted between two adjacent second light emitting diodes 200, and the adjacent first conductive lines 323 and second conductive lines 324 are conducted with each other.
Specifically, since the adjacent first conductive line 323 and the second conductive line 324 are conducted with each other, when a current passes through the first conductive line 323 or the second conductive line 324, the current also partially flows through the second conductive line 324 or the first conductive line 323, and therefore, the adjacent first conductive line 323 and the second conductive line 324 are conducted with each other, which can increase the cross-sectional area of a conductor, and reduce the resistance of the strip-shaped substrate 300, thereby reducing the line loss when the current passes through the strip-shaped substrate 300, reducing the voltage drop, and improving the utilization rate of the current.
As shown in fig. 1, in the above embodiment, optionally, the multicolor temperature light strip further includes a voltage dividing resistor 330, and the voltage dividing resistor 330 is disposed in series between two adjacent first light emitting diodes 100 and/or between two adjacent second light emitting diodes 200.
Specifically, the voltage dividing resistor 330 has a certain resistance, and thus the voltage dividing resistor 330 can divide a certain voltage in the series circuit, thereby reducing the voltage of each of the first light emitting diode 100 or the second light emitting diode 200, and also reducing the current in the series circuit. Therefore, during production, the voltage dividing resistor 330 with different resistance values can be replaced to achieve the customized effect of different powers.
EXAMPLE III

The opposite side of the front surface 310 on the strip-shaped substrate 300 is a back surface 340, the back surface 340 is provided with a second conductive layer 350, the second conductive layer 350 is patterned into a third electrode 351 and a fourth electrode 361, the third electrode 351 corresponds to the first electrode 321, the fourth electrode 361 corresponds to the second electrode 322, the strip-shaped substrate 300 is provided with a first through hole 370 for conducting the third electrode 351 and the first electrode 321, and the strip-shaped substrate 300 is provided with a second through hole 380 for conducting the fourth electrode 361 and the second electrode 322.
Specifically, since the third electrode 351 on the back surface 340 of the strip-shaped substrate 300 is electrically connected to the first electrode 321 on the front surface 310 through the first through hole 370, and the fourth electrode 361 on the back surface 340 of the strip-shaped substrate 300 is electrically connected to the second electrode 322 on the front surface 310 through the second through hole 380, the arrangement mode increases the cross-sectional area of the first electrode 321 and the second electrode 322 when the first electrode 321 and the second electrode 322 are electrically connected, reduces the resistance of the strip-shaped substrate 300, and fully utilizes the space on the back surface 340 of the strip-shaped substrate 300. Meanwhile, since the first conductive layer 320 and the second conductive layer 350 are generally made of metal, the metal has strong heat conduction and heat dissipation capabilities, and heat generated when the first light emitting diode 100 and the second light emitting diode 200 are powered on can be dissipated to the air through the first conductive layer 320 and the second conductive layer 350. Therefore, the arrangement of the second conductive layer 350 improves the heat dissipation efficiency of the strip substrate 300, which is beneficial to prolonging the service life of the first light emitting diode 100 and the second light emitting diode 200.
As shown in fig. 1 and 2, in the above embodiment, optionally, a plurality of strip-shaped substrates 300 are provided, one end of one strip-shaped substrate 300 is connected to the other end of another strip-shaped substrate 300, two first electrodes 321 of two adjacent strip-shaped substrates 300 are connected to each other and formed with first pads 325, and two second electrodes 322 of two adjacent strip-shaped substrates 300 are connected to each other and formed with second pads 326.
Specifically, one end of one strip-shaped substrate 300 can be connected with the other end of another strip-shaped substrate 300, two first electrodes 321 of two adjacent strip-shaped substrates 300 are connected with each other and are provided with first bonding pads 325, and two second electrodes 322 of two adjacent strip-shaped substrates 300 are connected with each other and are provided with second bonding pads 326, so that a user can cut along the position between the two adjacent strip-shaped substrates 300 when the multi-color temperature lamp strip is installed, the length of the multi-color temperature lamp strip is adjusted, and the installation is convenient. Meanwhile, since the first pad 325 and the second pad 326 are respectively located at both ends of the strip substrate 300, after two adjacent strip substrates 300 are separated, the multi-color temperature lamp strip can still be communicated with an external power supply through the first pad 325 and the second pad 326.
Example four
As shown in fig. 6, this embodiment proposes an arrangement manner of the third conductive layer 390 based on the first embodiment. One of the two rows of the plurality of light emitting sources is a plurality of first light emitting diodes 100, the other of the two rows of the plurality of light emitting sources is a plurality of second light emitting diodes 200, one side of the bar substrate 300 provided with the plurality of light emitting sources is a front surface 310, a third conductive layer 390 is arranged on the front surface 310, the third conductive layer 390 is patterned into a common electrode 391, a first sub-electrode 392 and a second sub-electrode 393, the common electrode 391 is positioned on one side of the bar substrate 300, the first sub-electrode 392 and the second sub-electrode 393 are positioned on the other side of the bar substrate 300, the plurality of first light emitting diodes 100 are connected in series between the common electrode 391 and the first sub-electrode 392, and the plurality of second light emitting diodes 200 are connected in series between the common electrode 391 and the second sub-electrode 393.
Specifically, by providing the common electrode 391, the first sub-electrode 392 and the second sub-electrode 393 on the front surface 310 of the bar substrate 300, a plurality of first light emitting diodes 100 are connected in series between the common electrode 391 and the first sub-electrode 392, and a plurality of second light emitting diodes 200 are connected in series between the common electrode 391 and the second sub-electrode 393. When the power supply electrode and the first sub-electrode 392 are turned on, the first light emitting diode 100 can be lit; when the power supply electrode and the first sub-electrode 392 are electrically connected, the second light emitting diode 200 can be turned on. Therefore, the third conductive layer 390 is disposed in such a way that the multi-color temperature lamp strip can control the light emitting diodes to emit light by controlling the conduction of the two circuits.
As shown in fig. 6, in the above embodiment, optionally, the area of the common electrode 391 is larger than the area of the first and second sub-electrodes 392, 393, respectively, and the area of the common electrode 391 is smaller than or equal to the sum of the area of the first and second sub-electrodes 392, 393.
Specifically, because two circuits in the third conductive layer 390 need to be conducted through the common electrode 391, the area of the common electrode 391 is set to be larger than the area of the first sub-electrode 392 and the area of the second sub-electrode 393, and the area of the common electrode 391 is smaller than or equal to the sum of the area of the first sub-electrode 392 and the area of the second sub-electrode 393, so that the third conductive layer 390 can reasonably distribute the areas of the common electrode 391, the first sub-electrode 392 and the second sub-electrode 393, and therefore the multi-color temperature lamp strip can reduce the resistance and avoid overlarge voltage drop no matter what color temperature the multi-color temperature lamp strip is switched to.
