Description

Technical Field

[0001] This utility model patent relates to the technical field of LED light sources, and more specifically, to LED light sources with diversified light emission modes. Background Technology

[0002] LED light sources have advantages such as small size, long lifespan, and high efficiency, and have become the mainstream in the lighting field.

[0003] LED light sources include a substrate with a light-emitting area and multiple light-emitting chips. A phosphor layer is filled in the light-emitting area and covers the light-emitting chips. In this way, the light emitted by the light-emitting chips passes through the phosphor layer to achieve the desired illumination effect.

[0004] In existing technologies, LED light sources often only use a single type of light-emitting chip, resulting in a single light-emitting mode and making it difficult to achieve diversified adjustment of the light-emitting mode. Utility Model Content

[0005] The purpose of this invention is to provide an LED light source with diversified light emission modes, aiming to solve the problem of the single light emission mode of LED light sources in the prior art.

[0006] This invention is achieved as follows: a multi-mode adjustable LED light source includes a substrate, on which a light-emitting area is provided, and a white channel is provided in the light-emitting area, which divides the light-emitting area into an adjacent main light area and a supplementary light area; the main light area is provided with multiple independently controlled blue light-emitting chips, and the supplementary light area is provided with multiple independently controlled red light-emitting chips; the light-emitting area is filled with a fluorescent adhesive layer, which covers multiple blue light-emitting chips and multiple red light-emitting chips respectively.

[0007] Furthermore, the peak wavelengths of the multiple red light-emitting chips are different.

[0008] Furthermore, the substrate is recessed downwards to form the light-emitting area, and the outer periphery of the light-emitting area has an outer peripheral wall arranged in a ring shape; the bottom of the light-emitting area has a bottom surface, the white channel is protruding on the bottom surface, and the blue light-emitting chip and the red light-emitting chip are disposed on the bottom surface.

[0009] Furthermore, the white channel is located in the middle of the light-emitting area, and the ends of the white channel are respectively connected to the outer peripheral wall.

[0010] Furthermore, multiple blue light-emitting chips are arranged in an array in the main light area.

[0011] Furthermore, multiple red light-emitting chips are arranged in an array in the supplementary lighting area.

[0012] Furthermore, along the upward direction of the light-emitting area, the outer peripheral wall is arranged outward from the light-emitting area, and the outer peripheral wall reflects light out of the light-emitting area.

[0013] Furthermore, the side of the white path has a side wall facing the main light area or the supplementary light area. Along the direction from bottom to top of the light-emitting area, the side wall is inclined inward from the outer peripheral wall, and the side wall emits light out of the light-emitting area.

[0014] Furthermore, the top of the fluorescent adhesive layer has a fluorescent top surface, the middle of which is recessed downwards to form a conical recessed area; the outer periphery of the recessed area has a conical wall, and along the direction from top to bottom of the recessed area, the conical wall is inclined outwards away from the recessed area.

[0015] The fluorescent adhesive layer is covered with a light-transmitting adhesive layer, which covers the top surface of the fluorescent layer and is embedded in the recessed area, thus becoming integrated with the fluorescent adhesive layer.

[0016] Furthermore, the light-transmitting adhesive layer has an upper portion located above the recessed area, the top of the upper portion being flat to form a disc-shaped light-transmitting top surface, the diameter of the light-transmitting top surface being smaller than the diameter of the top of the recessed area.

[0017] Compared with the prior art, the LED light source provided by this utility model has diversified light emission modes. Multiple blue light emission chips are independently controlled, and multiple red light emission chips are also independently controlled. In this way, as needed for functional light emission, a variety of control methods can be selected to achieve diversified light emission mode adjustment. Secondly, multiple blue light emission chips can supplement the red light emission chips, so that the light emitted by the light-transmitting fluorescent adhesive layer of the LED light source is closer to sunlight, achieving the effect of full-spectrum LED light source.

[0023] Reference Figure 1-2 The image shown is a preferred embodiment of the present invention.

[0024] The LED light source with diversified light emission modes includes a substrate 100, on which a light emission area 102 is provided. A white channel 500 is provided in the light emission area 102, dividing the light emission area 102 into a main light area 1021 and a supplementary light area 1022 arranged adjacently. The main light area 1021 is provided with multiple independently controlled blue light emission chips 200, and the supplementary light area 1022 is provided with multiple independently controlled red light emission chips 201. The light emission area 102 is filled with a phosphor layer 300, which covers multiple blue light emission chips 200 and multiple red light emission chips 201 respectively.

[0025] The aforementioned LED light source with diversified light emission modes features independent control of multiple blue light-emitting chips 200 and multiple red light-emitting chips 201. This allows for the selection of diverse control methods to meet functional light emission requirements, thereby achieving diversified light emission mode adjustment. Furthermore, the multiple blue light-emitting chips 200 can supplement the red light-emitting chips 201, making the light emitted by the LED light source's transparent fluorescent adhesive layer 300 closer to sunlight, thus achieving a full-spectrum LED light source effect.

[0026] In this embodiment, the peak wavelengths of the multiple red light-emitting chips 201 are different, so that the multiple red light-emitting chips 201 can achieve diverse light-emitting effects. The corresponding red light-emitting chip 201 can be turned on or off according to the actual lighting requirements.

[0027] In this embodiment, the substrate 100 is recessed downward to form the light-emitting area 102 described above. The outer periphery of the light-emitting area 102 has an outer peripheral wall 101 arranged in a surrounding manner. The bottom of the light-emitting area 102 has a bottom surface, and the white channel 500 is protruding on the bottom surface. The blue light-emitting chip 200 and the red light-emitting chip 201 are disposed on the bottom surface.

[0028] Alternatively, a dam can be formed on the substrate 100, which encloses the light-emitting area 102 described above.

[0029] In this embodiment, the white channel 500 is located in the middle of the light-emitting area 102, and the ends of the white channel 500 are respectively connected to the outer peripheral wall 101. In this way, the white channel 500 makes the light-emitting area 102 uniform, so as to achieve better supplementary lighting for the red light-emitting chip 201 by multiple blue light-emitting chips 200.

[0030] In this embodiment, multiple blue light-emitting chips 200 are arranged in an array in the main light area 1021, and multiple red light-emitting chips 201 are arranged in an array in the supplementary light area 1022.

[0031] In this embodiment, along the upward direction of the light-emitting area 102, the outer peripheral wall 101 is arranged outward from the light-emitting area 102. The outer peripheral wall 101 reflects light out of the light-emitting area 102. In this way, the outer peripheral wall 101 can reflect the light shining on it, which greatly improves the luminous efficiency of the LED light source.

[0032] In this embodiment, the side of the white channel 500 has a side wall 501 facing the main light area 1021 or the supplementary light area 1022. Along the direction from bottom to top of the light-emitting area 102, the side wall 501 is inclined inward away from the outer peripheral wall 101 and emits light out of the light-emitting area 102.

[0033] In this way, the side wall 501 of the white path 500 simultaneously reflects the light shining on it, thus simultaneously providing the light effect of the LED light source.

[0034] In this embodiment, the top of the fluorescent adhesive layer 300 has a fluorescent top surface, and the center of the fluorescent top surface is recessed downwards to form a cone-shaped recessed area. The outer periphery of the recessed area has a cone-shaped wall, which is arranged outwards from the recessed area along the top-to-bottom direction. A light-transmitting adhesive layer 400 is covered on the fluorescent adhesive layer 300, covering the fluorescent top surface and embedded in the recessed area, thus becoming integrated with the fluorescent adhesive layer 300.

[0035] By providing a recessed area in the fluorescent adhesive layer 300, and filling the recessed area with the light-transmitting adhesive layer 400, the light-transmitting adhesive layer 400 and the fluorescent adhesive layer 300 are bonded together as a whole, resulting in a more stable structure. Secondly, the conical walls of the recessed area can reflect light through it in multiple layers, greatly improving the luminous efficiency of the LED light source.

[0036] In this embodiment, the light-transmitting adhesive layer 400 has an upper portion located above the recessed area. The top of the upper portion is flat, forming a disc-shaped light-transmitting top surface 401. The diameter of the light-transmitting top surface 401 is smaller than the diameter of the top of the recessed area. In this way, the light-transmitting top surface 401 of the light-transmitting adhesive layer 400 can concentrate outwardly irradiated light to meet the needs of applications requiring high light concentration.

[0037] 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.
