Description

[0002] Currently, most lighting fixtures over 1.5 meters long are connected using multiple boards. However, traditional connection methods still have several drawbacks that need to be improved. First, traditional connection methods tend to result in uneven lighting, resulting in noticeable differences in brightness and darkness, reducing the visual effect and comfort of the lighting fixtures. Second, traditional connection methods underutilize the LEDs, resulting in low light efficiency and energy waste. Finally, traditional connection methods require the use of boards of different sizes, resulting in large board inventories and poor production efficiency, increasing the cost and time required to manufacture lighting fixtures.

For ease of understanding, the same components in the following embodiments will be denoted and described with the same reference numerals.

[0020] FIG. 1 is a circuit diagram of a lighting device having a wiring structure with high light efficiency according to one embodiment of the present invention. As shown in the figure, the lighting device 1 includes a driving power supply PS and a first light source substrate LS1. The first light source substrate LS1 includes a light source positive terminal LED+, a light source negative terminal LED-, a first connection portion 11, a second connection portion 12, a substrate 13, and a light-emitting module. The light source positive terminal LED+, the light source negative terminal LED-, the substrate 13, the first connection portion 11, the second connection portion 12, and the light-emitting module form the first light source substrate LS1. The lighting device 1 may be a mobile (portable) lighting device such as a flashlight or a portable searchlight, or may be a lighting fixture installed on the ceiling (or wall) of a building.

[0021] The driving power supply PS has a power supply positive terminal U+ and a power supply negative terminal U-. In one embodiment, the driving power supply PS may be a light emitting diode driver. In another embodiment, the driving power supply PS may be a driver for a fluorescent lamp, a light bulb, or other conventional light source.

[0022] The substrate 13 (shown by a two-dot chain line) has a light source connection part 131 and a power supply connection part 132. The light source connection part 131 is connected to the power supply connection part 132, and the power supply connection part 132 is connected to the power supply negative terminal U-.

[0023] One end of the first connector 11 (shown as a thin dashed line) is connected to the power supply positive terminal U+. In one embodiment, the first connector 11 may be any conventional electrical conductor.

[0024] One end of the second connector 12 (shown by a dashed line) is connected to the other end of the first connector 11, and the other end is connected to the light source positive terminal LED+. In one embodiment, the second connector 12 may be any conventional electrical wire.

[0025] The light-emitting module includes a first light source module 14A, a second light source module 14B, a third light source module 14C, and a fourth light source module 14D. One end of the first light source module 14A is connected to the light source positive terminal LED+, and the other end of the second light source module 14B is connected to the light source connection section 131. One end of the third light source module 14C is connected to the light source positive terminal LED+, and the other end of the second light source module 14C is connected to the light source connection section 131. One end of the fourth light source module 14D is connected to the light source positive terminal LED+, and the other end of the fourth light source module 14D is connected to the light source connection section 131. In this way, the driving power supply PS can drive the light-emitting module (including the first light source module 14A, the second light source module 14B, the third light source module 14C, and the fourth light source module 14D).

[0026] Furthermore, the impedance of the first light source module 14A, the impedance of the second light source module 14B, the impedance of the third light source module 14C, and the impedance of the fourth light source module 14D are equal to one another.

[0027] Therefore, the total impedance of the first light-emitting line formed by the first connection portion 11, the second connection portion 12, the first light source module 14A, and the substrate 13 is as shown in the following equation (1). M1=RA1+RB1+Ra+RA2………….(1) Here, M1 represents the total impedance of the first light-emitting line, RA1 represents the impedance of the first connection part 11, RB1 represents the impedance of the second connection part 12, Ra represents the impedance of the first light source module 14A, and RA2 represents the impedance of the substrate 13.

[0028] The total impedance of the second light-emitting line formed by the first connecting portion 11, the second connecting portion 12, the second light source module 14B, and the substrate 13 is as shown in the following equation (2). M2=RA1+RB1+Rb+RA2………….(2) Here, M2 represents the total impedance of the second light-emitting line, and Rb represents the impedance of the second light source module 14B.

[0029] The total impedance of the third light-emitting line formed by the first connecting portion 11, the second connecting portion 12, the third light source module 14C, and the substrate is as shown in the following equation (3). M3=RA1+RB1+Rc+RA2………….(3) Here, M3 represents the total impedance of the third light-emitting line, and Rc represents the impedance of the third light source module 14C.

[0030] The total impedance of the fourth light-emitting line formed by the first connecting portion 11, the second connecting portion 12, the fourth light source module 14D, and the substrate is as shown in the following equation (4). M4=RA1+RB1+Rd+RA2………….(4) Here, M4 represents the total impedance of the fourth light-emitting line, and Rd represents the impedance of the fourth light source module 14D.

[0031] As described above, the impedance Ra of the first light source module 14A, the impedance Rb of the second light source module 14B, the impedance Rc of the third light source module 14C, and the impedance Rd of the fourth light source module 14D are equal to one another (i.e., Ra=Rb=Rc=Rd). Therefore, the total impedance M1 of the first light-emitting line, the total impedance M2 of the second light-emitting line, the total impedance M3 of the third light-emitting line, and the total impedance M4 of the fourth light-emitting line are also equal to one another (i.e., M1=M2=M3=M4).

[0032] As can be seen from the above, the lighting fixture 1 can be configured by arranging multiple light emitting modules (first light source module 14A, second light source module 14B, third light source module 14C, and fourth light source module 14D) on a single substrate 13 to form multiple light emitting lines (first light emitting line, second light emitting line, third light emitting line, and fourth light emitting line). Furthermore, the lighting device 1 has a specially designed first connection portion 11, second connection portion 12, and substrate 13, which makes the total impedances of these light emitting lines equal to each other. This effectively improves both the visual effect and comfort of the lighting device 1. Furthermore, the lighting device 1 is more energy-efficient, allowing for a wider range of applications and meeting the needs of practical applications.

[0033] Furthermore, the lighting device 1 can arrange light emitting modules including a plurality of light emitting modules (first light source module 14A, second light source module 14B, third light source module 14C, and fourth light source module 14D) on a single substrate 13, thereby forming a plurality of light emitting lines (first light emitting line, second light emitting line, third light emitting line, and fourth light emitting line). The plurality of substrates 13 can be connected to each other. Therefore, the production of the lighting device 1 requires only one size of substrate 13, which does not increase the inventory of substrates 13, significantly improves production efficiency, and reduces manufacturing costs and time. Therefore, the overall cost of the lighting device 1 can be effectively reduced.

[0034] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the lighting device equipped with the wiring structure having high light efficiency of this embodiment should still fall within the scope of protection of the present invention.

[0035] FIG. 2 is a first explanatory diagram of a lighting device having a wiring structure with high light efficiency according to an embodiment of the present invention. Please refer to FIG. 1 as well. As shown in the figure, a first light source module 14A includes a first connection line 141A and a plurality of first light sources 142A. The first connection line 141A includes a plurality of first connection regions C1 and a plurality of first light-emitting regions L1, which are arranged alternately. The width of the first connection line 141A is Wd. Each first connection region C1 protrudes in a first direction A1 relative to a first reference line S1, and each first light-emitting region L1 protrudes in a second direction A2 relative to the first reference line S1. The first direction A1 is opposite to the second direction A2. The first direction A1 and the second direction A2 can be changed according to actual requirements. The plurality of first light sources 142A are respectively installed in the plurality of first light-emitting regions L1. The first reference line S1 passes through the connection point between any two adjacent first connection regions C1 and first light-emitting regions L1. The above-described wiring structure makes the first light source module 14A have a continuous rectangular wave shape.

[0036] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the lighting device equipped with the wiring structure having high light efficiency of this embodiment should still fall within the scope of protection of the present invention.

[0037] FIG. 3 is a second explanatory diagram of a lighting device having a wiring structure with high light efficiency according to one embodiment of the present invention. Please refer to FIG. 1 and FIG. 2 together. As shown in the figure, a second light source module 14B includes a second connection line 141B and multiple second light sources 142B. The second connection line 141B includes multiple second light-emitting regions L2 and multiple second connection regions C2, which are arranged alternately. Each second light-emitting region L2 protrudes in a first direction A1 relative to a second reference line S2, and each second connection region C2 protrudes in a second direction A2 relative to the second reference line S2. The multiple second light sources 142B are respectively installed in the multiple second light-emitting regions L2, and the multiple second light-emitting regions L2 correspond to the multiple first connection regions C1, respectively. The second reference line S2 passes through the connection points between any two adjacent second connection regions C2 and the second light-emitting regions L2. The above wiring structure makes the second light source module 14B have a continuous square wave shape.

[0038] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the lighting device equipped with the wiring structure having high light efficiency of this embodiment should still fall within the scope of protection of the present invention.

[0039] FIG. 4 is a third explanatory diagram of a lighting device having a wiring structure with high light efficiency according to one embodiment of the present invention. Please refer to FIG. 1 to FIG. 3 together. As shown in the figure, a third light source module 14C includes a third connection line 141C and multiple third light sources 142C. The third connection line 141C includes multiple third light-emitting regions L3 and multiple third connection regions C3, and the multiple third light-emitting regions L3 and the multiple third connection regions C3 are arranged in a staggered pattern. Each third light-emitting region L3 protrudes in a second direction A2 relative to a third reference line S3, and each third connection region C3 protrudes in a first direction A1 relative to the third reference line S3. The multiple third light sources 142C are respectively installed in the multiple third light-emitting regions L3, and the multiple third light-emitting regions L3 correspond to the multiple second light-emitting regions L2, respectively. The third reference line S3 passes through the connection points between any two adjacent third connection regions C3 and third light-emitting regions L3. The above wiring structure makes the third light source module 14C have a continuous square wave shape.

[0040] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the lighting device equipped with the wiring structure having high light efficiency of this embodiment should still fall within the scope of protection of the present invention.

[0041] FIG. 5 is a fourth explanatory diagram of a lighting device having a wiring structure with high light efficiency according to one embodiment of the present invention. Please refer to FIGS. 1 to 4 together. As shown in the figure, a fourth light source module 14D includes a fourth connection line 141D and a plurality of fourth light sources 142D. The fourth connection line 141D includes a plurality of fourth connection regions C4 and a plurality of fourth light-emitting regions L4, and the plurality of fourth light-emitting regions L4 and the plurality of fourth connection regions C4 are arranged in a staggered pattern. Each fourth connection region C4 protrudes in the second direction A2 relative to a fourth reference line S4, and each fourth light-emitting region L4 protrudes in the first direction A1 relative to the fourth reference line S4. The plurality of fourth light sources 142D are respectively installed in the plurality of fourth light-emitting regions L4, and the plurality of fourth light-emitting regions L4 correspond to the plurality of third connection regions C3, respectively. The first reference line S1, the second reference line S2, the third reference line S3, and the fourth reference line S4 are parallel to one another. The fourth reference line S4 passes through the connection point between any two adjacent fourth connection regions C4 and fourth light-emitting regions L4. The above-described wiring structure makes the fourth light source module 14D have a continuous rectangular wave shape.

[0042] In one embodiment, the first light sources 142A, the second light sources 142B, the third light sources 142C, and the fourth light sources 142D are light-emitting diodes (LEDs). In another embodiment, the first light sources 142A, the second light sources 142B, the third light sources 142C, and the fourth light sources 142D may be fluorescent lamps, incandescent lamps, or other conventional light sources.

[0043] The widths of the first connection line 141A, the second connection line 141B, the third connection line 141C, and the fourth connection line 141D are all equal to one another. That is, the widths of the second connection line 141B, the third connection line 141C, and the fourth connection line 141D are also Wd. The overall lengths of the first connection line 141A, the second connection line 141B, the third connection line 141C, and the fourth connection line 141D are also all equal to one another.

[0044] As can be seen from the above, the first light source module 14A, the second light source module 14B, the third light source module 14C, and the fourth light source module 14D have a special wiring structure. Therefore, the impedances of the first light source module 14A, the second light source module 14B, the third light source module 14C, and the fourth light source module 14D are equal to one another, achieving impedance matching. The above wiring structure, integrated with the first connection portion 11, the second connection portion 12, and the substrate 13, can evenly distribute current among the first light source module 14A, the second light source module 14B, the third light source module 14C, and the fourth light source module 14D, thereby improving the overall luminous efficiency of the lighting device 1. This effectively improves both the visual effect and comfort of the lighting device.

[0045] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the lighting device equipped with the wiring structure having high light efficiency of this embodiment should still fall within the scope of protection of the present invention.

[0046] Furthermore, conventional connection methods tend to cause uneven light emission from lighting devices, resulting in noticeable differences in brightness and darkness, thereby reducing the visual effect and comfort of the lighting device. Second, conventional connection methods underutilize light-emitting diodes, resulting in low light efficiency and energy waste. Finally, conventional connection methods require the use of different-sized boards, resulting in a large inventory of boards and poor production efficiency, increasing the cost and time required to manufacture lighting devices. In contrast, according to an embodiment of the present invention, a lighting device has light-emitting modules, each including multiple light source modules, arranged on a single board, forming multiple light-emitting lines. Furthermore, the lighting device has a specially designed first connection portion, second connection portion, and board, which equalize the overall impedance of these light-emitting lines. In this way, the light efficiency of the lighting device is significantly improved, its light emission is uniform, and noticeable differences in brightness and darkness are eliminated. Therefore, both the visual effect and comfort of the lighting device can be effectively improved.

[0047] Furthermore, according to an embodiment of the present invention, the lighting device has a specially designed first connector, second connector, substrate, and multiple light source modules, which can form a wiring structure with high light efficiency that can fully utilize the light emitting diodes, thereby significantly improving the light efficiency of the lighting device, making the lighting device more energy-efficient and more in line with future development trends.

[0048] Furthermore, according to the embodiment of the present invention, a lighting device can be formed with a wiring structure having high optical efficiency that can fully utilize light-emitting diodes, thereby significantly improving the optical efficiency of the lighting device and improving the overall performance of the lighting device, thereby broadening the application of the lighting device and meeting the needs of actual applications.

[0049] Furthermore, according to an embodiment of the present invention, a lighting device has a light emitting module including a plurality of light source modules arranged on a single substrate, forming a plurality of light emitting lines, and the plurality of substrates can be connected to each other. Therefore, only one size of substrate is required for the production of the lighting device, which does not increase the inventory of substrates, greatly improves production efficiency, and reduces manufacturing costs and time. Therefore, the overall cost of the lighting device can be effectively reduced.

[0050] Furthermore, according to the embodiments of the present invention, the design of the lighting device is simple, so that the desired effect can be achieved without significantly increasing the cost, and the lighting device has high commercial value. From the above, it can be seen that the lighting device with the wiring structure with high light efficiency according to the embodiments of the present invention can achieve very good technical effects.

[0051] Fig. 6 is an explanatory diagram of a lighting device having a wiring structure with high light efficiency according to another embodiment of the present invention. Please also refer to Figs. 1 to 5. As shown in the figure, the lighting device 1 includes a drive power supply PS, a first light source substrate LS1, and a second light source substrate LS2. The first light source substrate LS1 includes a light source positive terminal LED+, a light source negative terminal LED-, a first connection portion 11, a second connection portion 12, a substrate 13, and a light-emitting module. The structure of the first light source substrate LS1 is the same as that of the above embodiment (see Figs. 1 to 5), so further description will not be provided here. The structure of the second light source substrate LS2 is the same as that of the first light source substrate LS1.

[0052] As shown in the figure, the second connection portion 12 of the first light source substrate LS1 is connected (for example, by welding or other means) to the second connection portion 12 of the second light source substrate LS2. The light source negative terminal LED- of the first light source substrate LS1 may be connected to the light source negative terminal LED- of the second light source substrate LS2. Thus, multiple substrates 13 can be connected to one lighting device 1.

[0053] As can be seen from the above, the lighting device 1 has light-emitting modules, each including a plurality of light source modules, arranged on a single substrate 13, forming a plurality of light-emitting lines, and the plurality of substrates 13 can be connected to each other. Therefore, the production of the lighting device 1 requires only one size of substrate 13, which does not increase the inventory of substrates 13, greatly improves production efficiency, and reduces manufacturing costs and time. Therefore, the overall cost of the lighting device 1 can be effectively reduced.

[0054] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the lighting device equipped with the wiring structure having high light efficiency of this embodiment should still fall within the scope of protection of the present invention.
