[0046] In the prior art, LED lamps generally adopt the design concept of independently packaging a single LED chip in a separate lamp bead, but the actual utilization rate of the lens area of ​​this design is not high, resulting in the shackles of the light efficiency and long-range performance of the LED lamp. It is difficult to further optimize the lighting effect with the existing design.

[0047] Based on the above problems in the prior art, the utility model provides an LED light emitting mechanism, such as Figure 1 As shown, the LED light-emitting mechanism includes: a base 100, a conductive part 110 is arranged on one side of the base 100; a chip cluster 200, the chip cluster 200 includes a plurality of LED chips 210, the plurality of LED chips 210 include at least two types, the LED chips 210 are fixedly arranged on the other side of the base 100 and connected to the conductive part 110; an optical element 300, the optical element 300 is covered on one side of the base 100 corresponding to the chip cluster 200.

[0048] The utility model sets a chip cluster 200 on a base 100, and the chip cluster 200 includes a plurality of different types of LED chips 210, and covers the chip cluster 200 through an optical element 300. When in use, different LED chips 210 in the chip cluster 200 can cooperate to form light compensation, thereby increasing the total reflection area of ​​the optical element 300, thereby providing a better long-range effect while improving the uniformity and stability of the light effect, thereby optimizing the lighting effect of lamps using LED light-emitting mechanisms.

[0049] In the above embodiment, if Figure 1 As shown, the main body of the LED light-emitting mechanism of the utility model is composed of a base 100, a chip cluster 200 and an optical element 300, wherein the base 100 is specifically a plate-like structure for installing the chip cluster 200, and can be specifically made of ceramics, metals and other materials. A conductive part 110 is provided on one side of the base 100, and the conductive part 110 is used to connect the circuit with the chip cluster 200, so as to form power supply and circuit control for the chip cluster 200 when the LED light-emitting mechanism is installed in the device. In the present embodiment, the chip cluster 200 includes a plurality of LED chips 210. When the plurality of LED chips 210 are installed on the base 100, the conductive part 110 can be arranged in a plurality of forms such as series connection, parallel connection and independent connection corresponding to the plurality of LED chips 210, so as to achieve a plurality of use effects such as simultaneous activation or individual control activation, and the specific connection form is prefabricated according to the actual use requirements and the model of the product, and the present application does not limit this.

[0050] The optical element 300 includes a lens commonly used in LED light-emitting mechanisms. In the present embodiment, the optical element 300 is covered on one side of the base 100 corresponding to the chip cluster 200 and is fixedly connected to the base 100. The optical element 300 is used to reflect light when a plurality of LED chips 210 emit light, so as to achieve the effect of guiding light at a predetermined angle, light-emitting surface, etc.

[0051] In this embodiment, the chip cluster 200 includes a plurality of LED chips 210, and the plurality of LED chips 210 include at least two types. The color temperature, color, luminous intensity, etc. of the two types of LED chips 210 can be preset to be different. When the LED light-emitting mechanism is turned on, the two types of LED chips 210 can complement each other in light, thereby making full use of the reflection area of ​​the optical element 300, thereby achieving the design goal of further optimizing the lighting effect.

[0052] Based on the above embodiments, in one possible implementation of the present invention, the chip cluster 200 on the base 100 may be provided with several chips, such as Figure 2As shown, for example, in the first embodiment of the present invention, the above-mentioned chip clusters 200 can be provided with eight, and the plurality of chip clusters 200 are arranged in an array at a predetermined distance, specifically, they can be arranged in a rectangular array or a ring array. Correspondingly, the above-mentioned optical elements 300 are also provided with a plurality, and the plurality of optical elements 300 are arranged in a one-to-one correspondence with the plurality of chip clusters 200. In the present embodiment, different types of LED chips 210 are arranged in a single chip cluster 200, which can form an effect of fully utilizing the reflective surface with the corresponding optical element 300. At the same time, when the plurality of chip clusters 200 jointly improve the reflection efficiency, the overall luminous efficiency of the new LED light-emitting mechanism can be further improved, and the light transmittance efficiency of the plurality of optical elements 300 can be simultaneously improved, thereby finally achieving the effect of increasing the overall total reflection area and achieving a better long-range effect.

[0053] In another embodiment of the present invention, Figure 2 As shown, in the case where several chip clusters 200 are provided, the positions of the LED chips 210 in different chip clusters 200 can be arranged to achieve the coordination of the light effects produced by adjacent chip clusters 200, thereby achieving the effect of improving the stability of the light effect and the actual effect. Specifically, the several LED chips 210 in the above-mentioned chip cluster 200 are arranged in an array to form a coordinated layout of multiple LED chips 210 in a single chip cluster 200.

[0054] For this configuration, the present invention defines two specific layouts of the LED chips 210, one of which is as follows: Figure 2 and Figure 3 As shown, when the LED chips 210 in a chip cluster 200 are arranged in a rectangular array, several LED chips 210 of the same type in the same chip cluster 200 are staggered, that is, adjacent LED chips 210 are of different types. The advantage of such an arrangement is that when the chip cluster 200 emits light, different types of LED chips 210 can complement each other, which can improve the transmission utilization rate of the corresponding optical element 300. Figure 7 As shown, the same type of LED chips 210 in a chip cluster 200 are arranged in a ring shape, that is, a number of LED chips 210 of different types form a concentric ring pattern. The advantage of such an arrangement is that the light effect can be more concentrated, and another type of LED chip 210 can form a regionalized light supplement, thereby improving the transmission utilization rate of the optical element 300.

[0055] Furthermore, in the above embodiment, when there are multiple chip clusters 200, in addition to the layout of the LED chips 210 for light supplementation in a single chip cluster 200 from a microscopic perspective, there should also be a layout that cooperates with each other between adjacent chip clusters 200, that is, in adjacent chip clusters 200 on the base 100, the types of adjacent LED chips 210 are different. Taking the first embodiment of the utility model as an example, Figure 2 As shown, the chip cluster 200 at the upper left corner on the substrate includes two types of LED chips 210, which are arranged along the length direction of the substrate. Correspondingly, the second chip cluster 200 at the upper left corner on the substrate also includes two types of LED chips 210, which are also arranged along the length direction of the substrate. In order to make the adjacent chip clusters 200 cooperate, in this embodiment, the arrangement order of the two types of LED chips 210 in the two chip clusters 200 is set opposite, that is, the adjacent LED chips 210 are arranged in different types. When the LED light-emitting mechanism is turned on, in the adjacent chip clusters 200, the adjacent LED chips 210 not only supplement the LED chips 210 of their own chip clusters 200, but also play the role of supplementing the LED chips 210 of the adjacent chip clusters 200, so that a better lighting effect can be presented in the end.

[0056] For another example, in the second embodiment of the present utility model, Figure 3 As shown;

[0057] The chip cluster 200 at the upper left corner of the substrate includes four LED chips 210, and the four LED chips 210 are of two types. Therefore, in actual setting, the four LED chips 210 are arranged in a rectangular array, and the types of adjacent LED chips 210 are different, forming an arrangement state as shown in the figure. Correspondingly, the second chip cluster 200 at the upper left corner of the substrate also includes four LED chips 210, and the arrangement order is opposite to the arrangement of the first chip cluster 200 at the upper left corner, forming a setting state in which the types of adjacent LED chips 210 in different chip clusters 200 are different. When the new LED light-emitting mechanism is turned on, in adjacent chip clusters 200, adjacent LED chips 210 not only fill in the LED chips 210 of their own chip clusters 200, but also play a role in filling in the LED chips 210 of adjacent chip clusters 200, so that a better light-emitting effect can be presented in the end.

[0058] In this embodiment, other chip clusters 200 on the substrate also follow the same rules to set the order of LED chips 210. Therefore, while improving the reflection efficiency of the optical element 300 corresponding to a single chip cluster 200, the cooperation of multiple chip clusters 200 further improves the light-emitting effect, so that the device using the new LED light-emitting mechanism can not only achieve an increase in long-range distance, but also achieve a uniform light effect.

[0059] In another possible implementation of the utility model, when arranging a plurality of chip clusters 200 on the base 100, the chip clusters 200 on the base 100 can also be divided into groups so that the LED chips 210 of the chip clusters 200 in the same group are arranged in the same manner, and the types of adjacent LED chips 210 in adjacent chip clusters 200 of different groups are symmetrical.

[0060] Taking the third embodiment of the present utility model as an example, Figure 4 As shown;

[0061] In the present embodiment, a total of 8 chip clusters 200 are provided on the substrate, which are arranged in a rectangular array. In the present embodiment, the 8 chip clusters 200 can be divided into two groups with the center line of the length direction of the substrate as the boundary, forming two groups of chip clusters 200 that are symmetrical on the left and right, and each group has 4 chip clusters 200. In the present embodiment, within the chip clusters 200 of the same group, the arrangement of the four LED chips 210 is the same, and the arrangement of the LED chips 210 of the chip clusters 200 of the two groups is different. From the perspective of the group, the light effects of the two groups are arranged in a form symmetrical to the center line, which can also achieve a macro effect of complementary light effects.

[0062] More specifically, when performing a product type in which the chip clusters 200 are arranged in groups, a plurality of chip clusters 200 are arranged at predetermined relative positions, and the predetermined relative positions specifically include three situations, specifically:

[0063] They are symmetrically arranged along the parallel lines of the long sides of the cross section of the base 100;

[0064] Or, they are symmetrically arranged along the parallel lines of the wide sides of the cross section of the base 100;

[0065] Or, they are symmetrically arranged along a direction parallel to a diagonal line of a cross section of the base 100 .

[0066] Taking the fourth embodiment of the present utility model as an example, Figure 5 As shown:

[0071] The LED chips 210 of No. 4 and No. 8 are arranged symmetrically along the parallel lines of the long sides of the cross section of the base 100;

[0072] It should be noted that the configuration of the chip cluster 200 in this embodiment is only used to illustrate the rules and does not represent a specific product style. Those skilled in the art can apply the above rules according to actual needs when making products, and the protection scope of the utility model is not limited to Figure 5 The embodiment shown.

In combination with the accompanying drawings, those skilled in the art can know that:

[0076] The LED chips 210 of No. 4 and No. 6 are arranged symmetrically along the parallel lines of the wide sides of the cross section of the base 100;

[0077] The LED chips 210 of No. 2 and No. 5 are arranged symmetrically along the parallel lines of the long sides of the cross section of the base 100;
