The control board 20 is installed in the lamp housing 10, the LED light source component 30 is installed in the lamp housing 10, the LED light source component 30 is electrically connected to the control board 20, the lamp housing 10 is provided with a light outlet 11, the lens 40 is connected to the lamp housing 10 and is located at the light outlet 11, and the LED light source component 30 is turned on to emit light to the lens 40 and emit light for illumination. Figures 3 to 6 As shown, the LED light source component 30 includes a substrate 34 and a first LED chip group 31, a second LED chip group 32, and multiple groups of outer circle LED chip groups 33 mounted on the substrate 34.

Figure 3 As shown, a plurality of first LED chips 311, a plurality of second LED chips 321 and a plurality of third LED chips 331 are regularly distributed on the substrate 34, that is, a plurality of first LED chips 311 surround the second LED chip group 32, a plurality of third LED chips 331 of each group of outer ring LED chip groups 33 surround the first LED chip group 31, and two adjacent groups of outer ring LED chip groups 33 are arranged at intervals in the radial direction. Moreover, when the LED lamp is illuminated, the first LED chip group 31 and the second LED chip group 32 emit light at the same time; or, the first LED chip group 31, the second LED chip group 32 and at least one group of outer ring LED chip groups 33 emit light at the same time.

[0043] In the LED provided in the present application, the LED light source component 30 of the LED lamp includes a first LED chip group 31, a second LED chip group 32 and multiple groups of outer circle LED chip groups 33. The multiple first LED chips 311 of the first LED chip group 31 are arranged in series, the multiple second LED chips 321 of the second LED chip group 32 are arranged in series, the multiple third LED chips 331 of each group of outer circle LED chip groups 33 are arranged in series, the multiple groups of outer circle LED chip groups 33 are arranged in parallel, the outer circle LED chip group 33 is arranged in parallel with the second LED chip group 32, and the second LED chip group 32 and the outer circle LED chip group 33 are both arranged in series with the first LED chip group 31. Furthermore, a plurality of first LED chips 311, a plurality of second LED chips 321 and a plurality of third LED chips 331 are regularly distributed on the substrate 34, that is, a plurality of first LED chips 311 surround the second LED chipset group 32, a plurality of third LED chips 331 of each group of outer ring LED chipset groups 33 surround the first LED chipset group 31, and two adjacent groups of outer ring LED chipset groups 33 are radially spaced. When the LED lamp is used for lighting, the first LED chipset group 31 and the second LED chipset group 32 emit light at the same time, or the first LED chipset group 31, the second LED chipset group 32 and at least one group of outer ring LED chipset groups 33 emit light at the same time. In this way, when the LED lamp is used for lighting, the user can choose a lighting mode in which only the first LED chipset group 31 and the second LED chipset group 32 emit light at the same time to form a smaller light beam angle, or the user can choose a lighting mode in which the first LED chipset group 31, the second LED chipset group 32 and at least one group of outer ring LED chipset groups 33 emit light at the same time to form a larger light beam angle. That is to say, the user can change the LED lamp and select a variety of different light beam angles, so that the LED lamp can adapt to different requirements for light beam angles in different lighting scenes and meet lighting requirements.

[0044] The LED light source component 30 of the LED lamp is generally a COB light source (ie, a high-power integrated surface light source, Chip On Board Light), and the substrate 34 is an aluminum substrate, which is beneficial to improving the heat dissipation efficiency of the light source.

[0045] like Figure 2 , Figure 5As shown, the control board 20 includes a connection controller 21, a positive terminal 22 and a negative terminal 23. The positive terminal 22 and the negative terminal 23 are electrically connected to the positive line and the negative line of the external circuit through the lamp holder 12 on the lamp housing 10. In addition, the input end of the first LED chipset 31 is electrically connected to the positive terminal 22. The connection controller 21 includes a plurality of connection electrodes 211, one of which is a first electrode electrically connected to the output end of the second LED chipset 32, and the remaining connection electrodes 211 are second electrodes. The plurality of second electrodes are electrically connected to the output ends of the plurality of outer ring LED chipsets 33 in a one-to-one correspondence. In addition, the control board 20 also includes a control switch 24, such as Figure 1 and Figure 2 As shown, when the LED lamp is lighting, the user manipulates the control switch 24 so that the first electrode is electrically connected to the negative terminal 23 alone, or the first electrode and at least one second electrode are electrically connected to the negative terminal 23 together. When the first electrode is electrically connected to the negative terminal 23 alone, the first LED chipset 31 and the second LED chipset 32 ​​emit light simultaneously to form a lighting mode with a smaller light beam angle for lighting; when the first electrode and at least one second electrode are electrically connected to the negative terminal 23 together, the first LED chipset 31, the second LED chipset 32 ​​and at least one group of outer ring LED chipset 33 emit light simultaneously to form a lighting mode with a larger light beam angle for lighting.

[0046] In this embodiment, the LED lamp is provided with a driving circuit. The driving circuit can be arranged on the control board 20, or the driving circuit can be arranged on the substrate 34 of the LED light source component 30. The input end of the driving circuit is electrically connected to the controller 21, and the output end of the driving circuit is electrically connected to the first LED chip group 31, the second LED chip group 32 and the outer ring LED chip group 33 of the LED light source component 30. By operating the control switch 24 to turn on the driving circuit, the driving circuit turns on the corresponding chip group of the LED light source component 30, thereby driving the LED light source component 30 to emit light.

[0047] like Figure 5As shown, a connecting branch 212 is provided between the output ends of two adjacent groups of outer circle LED chipsets 33, and a diode 213 is provided in the connecting branch 212. Moreover, among the output ends of the two adjacent groups of outer circle LED chipsets 33, the output end of the outer circle LED chipset 33 close to the first LED chipset 31 is electrically connected to the positive electrode of the diode 213 of the corresponding connecting branch 212, and the output end of the outer circle LED chipset 33 far from the first LED chipset 31 is electrically connected to the negative electrode of the diode 213 of the corresponding connecting branch 212. In this embodiment, the outer circle LED chipsets 33 of the LED lamp are divided into two groups, namely the third LED chipset 333 and the fourth LED chipset 334 (i.e., the plurality of groups of outer circle LED chipsets 33 include the third LED chipset 333 and the fourth LED chipset 334, as shown in FIG. 1 ). Figure 5 Therefore, in this embodiment, a connecting branch 212 is provided between the output end of the third LED chipset group 333 and the output end of the fourth LED chipset group 334, a diode 213 is provided on the connecting branch 212, and the anode of the diode 213 on the connecting branch 212 is electrically connected to the output end of the third LED chipset group 333, and the cathode of the diode 213 on the connecting branch 212 is electrically connected to the output end of the fourth LED chipset group 334. In this embodiment, Figure 5 As shown, when the user selects the lighting mode in which only the first LED chipset 31 and the second LED chipset 32 ​​emit light simultaneously to form a smaller light beam angle for lighting, the user controls the control switch 24 so that the first electrode is electrically connected to the negative terminal 23 alone, that is, as shown in FIG. Figure 5 As shown, the connection electrode No. 1 in the connection controller 21 is electrically connected to the negative terminal 23, while the connection electrode No. 2 and the connection electrode No. 3 are both disconnected from the negative terminal 23. At this time, the first LED chip group 31 and the second LED chip group 32 emit light at the same time. Figure 7 As shown, it shows the simulated illumination and light distribution when the first LED chipset 31 and the second LED chipset 32 ​​emit light simultaneously. Alternatively, when the user selects the lighting mode in which the first LED chipset 31, the second LED chipset 32 ​​and at least one group of outer ring LED chipset 33 emit light simultaneously to form a larger light beam angle, the user controls the control switch 24 so that the first electrode can be electrically connected to the negative terminal 23 together with at least one second electrode. That is, Figure 5 As shown, the connection electrode No. "1" and the connection electrode No. "2" in the connection controller 21 are both electrically connected to the negative terminal 23 and the connection electrode No. "3" is disconnected from the negative terminal 23. At this time, the first LED chip group 31, the second LED chip group 32 and the third LED chip group 333 emit light at the same time. Figure 8As shown, it shows the simulated illumination and light distribution of the first LED chipset 31, the second LED chipset 32 ​​and the third LED chipset 333 emitting light simultaneously; it can be that the connection electrode No. "1" and the connection electrode No. "3" in the connection controller 21 are both electrically connected to the negative terminal 23 and the connection electrode No. "2" is disconnected from the negative terminal 23. At this time, the first LED chipset 31, the second LED chipset 32, the third LED chipset 333 and the fourth LED chipset 334 emit light simultaneously, as shown in FIG. Fig. 9 , which shows the simulated illumination and light distribution of the first LED chipset 31, the second LED chipset 32, the third LED chipset 333 and the fourth LED chipset 334 emitting light simultaneously. Therefore, in this embodiment, the user can change the LED lamp to select three different light beam angles, so that the LED lamp can adapt to three different requirements for light beam angles in three different lighting scenes.

[0048] When the plurality of first LED chips 311, the plurality of second LED chips 321 and the plurality of third LED chips 331 are regularly distributed on the substrate 34, as shown in FIG. Figure 3 As shown, the first LED chip group 31 includes four first LED chips 311, and the four first LED chips 311 and the plurality of second LED chips 321 are distributed in a rectangular array, and the four first LED chips 311 are respectively located at the four corners of the rectangular array. In this embodiment, the second LED chip group 32 includes 12 second LED chips 321 (i.e., 12 N1 chips). And, as Figure 3 As shown, the third LED chips 331 of the third LED chip group 333 are equally divided into four parts. In this embodiment, the third LED chip group 333 includes 12 third LED chips 331, each of which has 3 third LED chips 331 (i.e., 12 N2 chips are equally divided into 4 parts, each of which has 3 N2 chips). The four third LED chips 331 are arranged in a one-to-one correspondence at the four side areas of the rectangular array. Figure 3 As shown, each third LED chip 331 is arranged in a straight line parallel to the side of the rectangular array. Figure 3 As shown, the plurality of third LED chips 331 of the fourth LED chip group 334 are evenly distributed in a circle with the center of the rectangular array as the center. In this embodiment, the fourth LED chip group 334 includes 12 third LED chips 331 (ie, 12 N3 chips).

[0049] In the LED lamp of the present application, the lens 40 is a Fresnel lens. The Fresnel lens is also called a spiral lens, one side of the lens surface is smooth, and the other side of the lens surface is engraved with concentric circles from small to large, and its texture is designed according to the interference, disturbance, relative sensitivity and receiving angle requirements of light.

[0050] like Figure 2 As shown, the LED lamp further includes a heat dissipation inner shell 50, which is installed in the lamp housing 10, and includes a flat plate portion 51 and a skirt portion 52 circumferentially connected to the circumferential edge of the flat plate portion 51. The substrate 34 is attached to the side of the flat plate portion 51 facing the lens 40, so that when the LED light source component 30 emits light, the heat generated by the LED light source component 30 can be quickly transferred to the flat plate portion 51, and then the flat plate portion 51 transfers the heat to the skirt portion 52, and the skirt portion 52 is attached to the inner wall of the lamp housing 10, so that the skirt portion 52 transfers the heat to the lamp housing 10, and the lamp housing 10 eventually dissipates the heat to the external air, which is conducive to improving the heat dissipation efficiency.

[0051] The above is a specific description of the LED lamp with three different light beam angles of the present application.

[0052] like Figure 4 As shown, relative to the above-mentioned LED lamp with three different light beam angles, in some other embodiments of the present application, when the user selects a lighting mode in which only the first LED chipset 31 and the second LED chipset 32 ​​emit light simultaneously to form a smaller light beam angle for lighting, the user operates the control switch 24 to electrically connect the first electrode alone to the negative terminal 23, that is, as shown in FIG. Figure 4 As shown, the connection electrode "1" in the connection controller 21 is electrically connected to the negative terminal 23, while the connection electrode "2" and the connection electrode "3" are both disconnected from the negative terminal 23. Alternatively, when the user selects the lighting mode in which the first LED chipset 31, the second LED chipset 32 ​​and at least one group of outer ring LED chipset 33 emit light simultaneously to form a larger light beam angle for lighting, the user controls the control switch 24 so that the first electrode can be electrically connected to the negative terminal 23 together with at least one second electrode, that is, as Figure 4As shown, the connection electrode No. 1 and the connection electrode No. 2 in the connection controller 21 may be electrically connected to the negative terminal 23, and the connection electrode No. 3 may be disconnected from the negative terminal 23; the connection electrode No. 1 and the connection electrode No. 3 in the connection controller 21 may be electrically connected to the negative terminal 23, and the connection electrode No. 2 may be disconnected from the negative terminal 23; or the connection electrode No. 1, the connection electrode No. 2, and the connection electrode No. 3 in the connection controller 21 may be electrically connected to the negative terminal 23. Therefore, in this embodiment, the user can change the LED lamp to select four different light beam angles, so that the LED lamp can adapt to four different requirements for light beam angles in four different lighting scenarios. Compared with the above-mentioned LED lamp with three different light beam angles, this LED lamp has the same structure except that "there is no connecting branch 212 between the output end of the third LED chip group 333 and the output end of the fourth LED chip group 334, and there is no diode 213 in the connecting branch 212", which will not be repeated here.

[0053] like Figure 6 As shown, relative to the above-mentioned LED lamp with three different light emitting beam angles, in some other embodiments of the present application, the LED lamp has three or more groups of outer ring LED chipsets 33. This embodiment takes three groups of outer ring LED chipsets 33 as an example, and the three groups of outer ring LED chipsets 33 are arranged in sequence along the radial direction. Among the output ends of two adjacent groups of outer ring LED chipsets 33, the output end of the outer ring LED chipset 33 close to the first LED chipset 31 is electrically connected to the positive electrode of the diode 213 of the corresponding connecting branch 212, and the output end of the outer ring LED chipset 33 far from the first LED chipset 31 is electrically connected to the negative electrode of the diode 213 of the corresponding connecting branch 212. Relative to the above-mentioned LED lamp with three different light emitting beam angles, this LED lamp has a fourth light emitting beam angle in addition to the same three different light emitting beam angles, that is, as Figure 6 As shown, the connection electrodes "1" and "4" in the connection controller 21 are both electrically connected to the negative terminal 23, and the connection electrodes "2" and "3" are both disconnected from the negative terminal 23. At this time, the first LED chip group 31, the second LED chip group 32 and the three outer circle LED chip groups 33 emit light at the same time. In addition, compared with the above-mentioned LED lamp with three different light beam angles, the LED lamp has the same structure except for the above structure, which will not be repeated here.

[0054] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
