[0077] In some embodiments, the direct current conversion circuit 1025 can be arranged inside the lamp tube 1022 and at one end or both ends of the lamp plate 1023.

[0078] In some embodiments, the illuminating lamp 102 further comprises a lamp head 1029 arranged at both ends of the lamp tube 1022 and connected with the lamp tube 1022, and the direct current conversion circuit 1025 can be arranged inside the lamp head 1029.

[0079] In some embodiments, the lamp tube 1022 can be a double-end lamp tube, i.e. the lamp head of the lamp tube is arranged at both ends of the lamp tube, and the double-end lamp tube can include a straight lamp tube.

[0080] In other embodiments, the lamp tube 1022 can be a single-end lamp tube, i.e. the lamp head of the lamp tube is arranged at one end of the lamp tube, and the single-end lamp tube can include a U-shaped, ring-shaped, H-shaped, double-U-shaped, square-shaped, spherical or spiral-shaped lamp tube.

[0084] Reference is made to Figure 6 in combination with reference to Figure 4 , Figure 6 the driving circuit of the lighting device 100 shown in the embodiments of the present application. Figure 4

[0085] Unlike the conventional LED driving power supply outputting direct current, the LED driving power supply 101 of the embodiments of the present application outputs high-frequency alternating current, which is supplied to the LED lighting lamp 102 with built-in direct current conversion circuit through the wiring terminal 103. Figure 6 V s is the equivalent output voltage of the driving power supply 101, Z s is the equivalent output impedance of the driving power supply 101, Z w is the equivalent impedance of the impedance branch of the wiring terminal 103, C w is the equivalent capacitance of the impedance branch of the wiring terminal 103, ω = 2πf, f is the working frequency, Z L is the equivalent load impedance of the lighting lamp 102, then the load current I L of the lighting lamp 102 is:

[0086] wherein Z w = 1 / (jωC W ).

[0087] As can be seen from the above formula, under the condition that the parameters of the driving power supply 101 and the lighting lamp 102 remain unchanged, the load current I L of the lighting lamp 102 can be changed by adjusting the capacitance C W of the wiring terminal 103.the size of the output lumens of the lighting lamp 102. Since generally, Z s is much greater than Z L , when Z w is much greater than Z L , and Z s is comparable or close to Z w , or Z s is much greater than Z w , all of them can obviously adjust the working current of the lighting lamp 102.

[0088] In some embodiments, the impedance of the impedance element 1033 of the terminal 103 can be determined according to the output lumens (or working current I L ) of the lighting lamp 102, the output voltage V S of the driving power supply 101, and the equivalent output impedance Z s of the driving power supply 101. When the impedance element 1033 includes a capacitor, the capacitance of the capacitor can be determined according to the output lumens (or working current I L ) of the lighting lamp 102, the output voltage V S of the driving power supply 101, the equivalent output impedance Z s of the driving power supply 101, and the output working frequency f of the driving power supply 101.

[0089] Since the conventional LED driving power supply outputs direct current, the voltage / current specification must match the LED lamp. Different environments have different requirements for the illumination of LED lamps, and different specifications of LED lamps and different parameters of driving power supplies need to be installed. Changing the output specification parameters of the programmable driving power supply by programming or programming to match the specification requirements of different LED lamps can only be completed by professional engineers, and does not conform to the on-site operation habits of lamp installation and modification personnel, and therefore is not convenient for large-scale promotion.

[0090] However, the embodiment of the present application does not use a direct current output LED driving power supply to power the LED lighting lamp, but uses an LED driving power supply outputting high-frequency alternating current to power the alternating current LED lighting lamp, and connects a high-frequency coupling capacitor in the power supply circuit. The alternating current LED lamp tube has a built-in direct current conversion circuit, which can rectify the coupled high-frequency alternating current into direct current output to the LED lamp panel to light the LED light emitting element. Different specifications of the terminal have different capacities of the capacitor, and connecting different specifications of the terminal is equivalent to changing the size of the capacitor connected to the driving circuit, thereby changing the load current flowing through the LED light emitting element and the output lumens, and finally completing the setting of the illumination of the lighting lamp.

[0091] Since the terminal without the impedance element is a common accessory in the process of lamp modification and installation, and is familiar to the daily installation personnel, the terminal of the embodiment of the present application does not need to master complex programming skills, and is suitable for the on-site operation habit of the installation and modification personnel, and is suitable for large-area promotion. By configuring terminals of multiple specifications, a large number of LED lighting lamps and driving power supplies of different specifications, parameters and models can be avoided, and the production and inventory management costs of manufacturers and engineering companies are greatly saved.

[0092] It should be noted that the impedance element 1033 of the terminal 103 of the embodiment of the present application can include an inductance element or a resistance element in addition to a capacitance element, and can also change the working current of the lighting lamp 102. However, the series connection of the resistance element in the driving circuit increases additional loss, and the system efficiency is not as high as that of the series connection of the capacitance. Although the series connection of the inductance element in the driving circuit does not increase loss, the volume and cost of the inductance element are higher than those of the capacitance element, and therefore the impedance element 1033 of the terminal 103 is preferably a capacitance element.

[0093] The foregoing Figure 4 The embodiment takes the lighting device including one lighting lamp as an example to describe the structure of the terminal of the lighting device of the embodiment of the present application and the access mode of the terminal in the lighting circuit. However, the embodiment of the present application is not limited thereto, and the structure of the terminal and the access mode of the terminal in the lighting circuit are further described below with the lighting device including multiple lighting lamps as an example.

Accordingly, the lamp pin 6021 can include two first lamp pins 6021a arranged at both ends of the lamp tube 6022 respectively, and two second lamp pins 6021b arranged at both ends of the lamp tube 6022 respectively. Wherein the two first lamp pins 6021a are coupled with two ends of the first light emitting element 6024a through the lamp plate 6023 respectively, and the two second lamp pins 6021b are coupled with two ends of the second light emitting element 6024b through the lamp plate 6023 respectively.

[0116] As

[0117] (a) shows, in some embodiments, the illuminating lamp 602 further includes two direct current conversion circuits: a first direct current conversion circuit 6025a and a second direct current conversion circuit 6025b, which can be arranged at both ends of the lamp plate 6023 respectively. With reference to Figure 12 (b) and (c), Figure 12 Figure 12 ​(b) and (c) respectively show the circuit structure of the second DC conversion circuit 6025b and the first DC conversion circuit 6025a, wherein the first DC conversion circuit 6025a is adapted to convert AC into DC, two input terminals of the first DC conversion circuit 6025a can be coupled with the two first lamp pins 6021a respectively, so as to be coupled with the first group of output terminals (al, a4) of the driving power supply 601, two output terminals of the first DC conversion circuit 6025a can be coupled with both ends of the first light emitting element 6024a through the lamp board 6023, so as to provide stable DC for the first light emitting element 6024a and drive the first light emitting element 6024a to emit light.

[0118] With continued reference to Figure 11 , the first group of output terminals (al, a4) of the driving power supply 601 are coupled with both ends of the first light emitting element 6024a through the two first lamp pins 6021a, forming a first driving loop, and the second group of output terminals (a2, a3) of the driving power supply 601 are coupled with both ends of the second light emitting element 6024b through the two second lamp pins 6021b, forming a second driving loop.

[0119] In some embodiments, the lighting device 600 can include a first wiring terminal 603a and a second wiring terminal 603b, which can respectively include one impedance branch, wherein the first wiring terminal 603a can be connected to the first driving loop, and the second wiring terminal 603b can be connected to the second driving loop.

[0120] In some embodiments, the lighting device 600 can also include only one wiring terminal 603 (as shown in the dashed box in Figure 11 ), which can include two impedance branches, one impedance branch of the one wiring terminal 603 is connected to the first driving loop, and the other impedance branch is connected to the second driving loop.

[0121] Since the first light emitting element 6024a and the second light emitting element 6024b are respectively provided with the terminal in the driving circuit, the working current of the first light emitting element 6024a and the second light emitting element 6024b can be respectively adjusted. By respectively connecting the terminal with specific impedance in the first driving circuit and the second driving circuit, the output lumens of the first light emitting element 6024a and the second light emitting element 6024b can be respectively set, so as to realize the setting of the overall color temperature of the lighting lamp 602.

[0122] The lighting device of the embodiment can realize the setting of the color temperature and the output lumens of the lighting lamp 602 by connecting the terminals with different impedances in the driving circuit of the lighting lamp, so as to adapt to different requirements of different application scenarios on the lighting illumination and the light color temperature. For some occasions requiring high lighting illumination and white light, such as work places or operating tables, the terminal with relatively small impedance can be connected in series in the driving circuit of the first light emitting element emitting white light, and the terminal with relatively large impedance can be connected in series in the driving circuit of the second light emitting element emitting red light, so that the lighting lamp 602 outputs mixed light with high lumens and color temperature close to white light; and for some occasions requiring low lighting illumination and soft light, such as coffee shops or bedrooms, the terminal with relatively large impedance can be connected in series in the driving circuit of the first light emitting element emitting white light, and the terminal with relatively small impedance can be connected in series in the driving circuit of the second light emitting element emitting red light, so that the lighting lamp 602 outputs mixed light with low lumens and color temperature close to yellow light.

[0123] The terminal and the lighting device of the embodiment can be applied to LED lamps, including but not limited to Troffer, High Bay, Low Bay, Pendant and various embedded lamps.

[0124] The driving power in the lighting device of the above-mentioned embodiment of the application can be a LED ballast, and the lighting lamp can be a LED lamp tube.

[0125] In summary, the terminal of the embodiment of the present application comprises at least one impedance branch, since the impedance branch comprises two first conductive contacts and one or more impedance elements connected in series between the two first conductive contacts, the impedance elements can adjust the current of the connected circuit when the terminal is connected to the circuit through the two first conductive contacts. In practical application, by configuring the terminal with specific impedance, the working current of the connected circuit can be set; by configuring multiple terminals with different impedances and selecting the terminal to connect to the circuit, the working current of the connected circuit can be adjusted on site, for example, the terminal can be used for the retrofit and installation of lamps in lighting circuits.

[0126] Further, the impedance elements comprise capacitors, and when the terminal is connected to the circuit, the capacitor elements do not increase additional power loss of the circuit, and in addition, since the capacitor has small volume and low cost, using the capacitor as the impedance element of the terminal has great practical value.

[0127] Further, the terminal further comprises at least one second conductive contact, the second conductive contact is disconnected or short-circuited with the first conductive contact, when the terminal is connected to the circuit through the first conductive contact and the second conductive contact, the corresponding circuit can be controlled to be disconnected or conducted; or, the terminal further comprises multiple second conductive contacts, the multiple second conductive contacts are disconnected or short-circuited, when the terminal is connected to the circuit through the multiple second conductive contacts, the corresponding circuit can be controlled to be disconnected or conducted. Therefore, the terminal of the embodiment of the present application comprises multiple types of conductive contacts, when the terminal is connected to the circuit through different types of conductive contacts, different functions can be realized, and the integration of the terminal is improved.

[0128] The embodiment of the present application also provides a lighting device comprising a driving power supply, a lighting lamp and the terminal of the embodiment of the present application, the output end of the driving power supply is coupled with two ends of the lighting lamp to form a driving circuit, and the two first conductive contacts of the at least one impedance branch of the terminal are connected to the driving circuit to realize the adjustment of the working current of the lighting lamp, and further realize the adjustment of the output lumens of the lighting lamp. In practical application, the manufacturer can produce multiple terminals with different specifications, and the lamp installation or maintenance personnel only need to directly insert the electrical connection wire between the driving power supply and the lighting lamp into the first conductive contact of the terminal with the corresponding specification, so that the on-site adjustment of the illuminance of the lighting lamp can be conveniently, quickly and safely realized, to meet different needs of different environments for lighting illuminance, and the embodiment of the present application is particularly suitable for large-scale installation and retrofit of lighting lamps.

[0129] The lighting device of the embodiment of the present application has the following advantages: first, the scheme greatly reduces the product specifications of the lighting lamp and the driving power supply, because only a small number of specifications of the lighting lamp and the driving power supply are needed to be matched with a plurality of specifications of the terminal, the lighting demand in a wide range can be easily met, and the production and inventory management costs of the manufacturers and engineers are greatly saved; second, because the cost and size of the terminal are small, the matching problem between the lighting lamp and the driving power supply can be easily solved; third, compared with the programmable LED driving power supply, the terminal does not require high professional skills of the staff installing the lamp on site, and the use method is the same as the wiring method of the traditional lamp, which is conducive to the promotion of new technology.

[0130] Further, the impedance element of the terminal is connected in series with the lighting lamp, so that the terminal can be connected to the driving circuit of the lighting lamp, and the working current of the lighting lamp can be accurately adjusted.
