[0021] Reference Figs. 1-2 The image shown is a preferred embodiment of the present invention.

[0022] A multi-mode LED light source includes a substrate 100. The substrate 100 has a recessed area that surrounds and forms a light-emitting area. The light-emitting area has two longitudinally and transversely arranged partition walls 300, which divide the light-emitting area into four independently arranged partitions 101. White light chip 204, red light chip 201, green light chip 202, and blue light chip 203 are respectively arranged in the four partitions 101.

[0023] The multi-mode LED light source provided above divides the light-emitting area into four independently arranged partitions 101 through two partition walls 300. In addition, white light chip 204, blue light chip 203, red light chip 201 and green light chip 202 are arranged in the four partitions 101 respectively. In this way, the white light chip 204, blue light chip 203, red light chip 201 and green light chip 202 can be independently arranged in the light-emitting area. By controlling the light emission of different chips, the multi-mode light emission of the entire LED light source can be realized to achieve different lighting effects.

[0024] In this embodiment, the light-emitting area is filled with a fluorescent adhesive layer 400, which covers four partitions 101, and respectively covers a white light chip 204, a red light chip 201, a green light chip 202, and a blue light chip 203. Thus, the light emitted by the white light chip 204, the red light chip 201, the green light chip 202, and the blue light chip 203 can pass through the fluorescent adhesive layer 400 before illuminating outwards.

[0025] In this embodiment, the partition wall 300 has an inner sidewall 301 facing the partition 101. Along the height direction of the partition wall 300, the inner sidewall 301 is inclined away from the partition 101. In this way, part of the light emitted by the chip will shine on the inner sidewall 301. Since the inner sidewall 301 is inclined, it can reflect the light shining on it, which greatly improves the luminous efficiency of the LED light source.

[0026] In this embodiment, the top of the partition wall 300 has a top surface 302, which is arranged in a flat shape. Of course, the top surface 302 can also be arranged in other shapes according to actual needs.

[0027] In this embodiment, the top surface 302 is positioned below the top of the substrate 100. This facilitates the placement of the phosphor layer 400.

[0028] This arrangement facilitates the formation of an integral structure from the fluorescent adhesive layer 400.

[0029] In this embodiment, the outer periphery of the light-emitting area has an outer peripheral sidewall 103, which is arranged facing the light-emitting area, and the end of the partition wall 300 is connected to the outer peripheral sidewall 103. In this way, the multiple partitions 101 divided by the partition wall 300 are arranged independently.

[0030] In this embodiment, the outer peripheral sidewall 103 is arranged at an angle away from the light-emitting area along the height direction of the outer peripheral sidewall 103. In this way, when the light emitted by the chip shines on the outer peripheral sidewall 103, the light can be reflected outward due to the inclined arrangement of the outer peripheral sidewall 103.

[0031] In this embodiment, along the height direction of the outer peripheral sidewall 103, a plurality of upwardly arranged steps 102 are formed on the outer peripheral sidewall 103; the outer periphery of the fluorescent adhesive layer 400 has an outer peripheral portion, which abuts against the outer peripheral sidewall 103 and embeds a plurality of steps 102.

[0032] By arranging multiple steps 102, it is convenient for the outer periphery of the fluorescent adhesive layer 400 to overlap and fit with the outer periphery sidewall 103, so as to ensure that the fluorescent adhesive layer 400 is arranged in an arched shape, and also to make the structure of the fluorescent adhesive layer 400 more stable.

[0033] In this embodiment, the top of the fluorescent adhesive layer 400 has an adhesive layer top surface 402, and a matte adhesive layer 500 covers the adhesive layer top surface 402. The outer periphery of the matte adhesive layer 500 abuts against the outer peripheral sidewall 103, and the matte adhesive layer 500 is convex upward with an arc surface. By arranging the matte adhesive layer 500, the fluorescent adhesive layer 400 can be protected. The matte adhesive layer 500 is generally a light-transmitting adhesive layer. The light projected from the fluorescent adhesive layer 400 passes through the matte adhesive layer 500 and shines outward.

[0034] In this embodiment, the middle part of the top surface 402 of the adhesive layer is flat, forming a central plane 401, and the top adhesive layer 500 covers the central plane 401. By forming the central plane 401, the top adhesive layer 500 can better cooperate with the fluorescent adhesive layer 400.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
