Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead brackets, specifically a double groove bracket. Background Technology

[0002] In LED lighting and display technology, traditional LED lighting systems mostly rely on blue LED chips interacting with phosphors to produce white light; however, traditional LED lighting systems have low energy efficiency at low color temperatures. In recent years, phosphorless multi-color LED technology has gradually gained attention. This technology achieves efficient color output and flexible color temperature adjustment by directly combining multiple primary color LEDs (such as red, green, and blue); however, phosphorless LED lighting systems have low energy efficiency at high color temperatures. In view of the limitations of the two technologies mentioned above, in order to better balance the needs of energy efficiency and color temperature adjustment, we provide a dual-groove bracket. Utility Model Content

[0003] The purpose of this utility model is to improve and innovate upon the shortcomings and problems existing in the background technology, and to provide a double groove bracket.

[0019] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figures 1-2 This utility model provides a double-groove bracket, including a bracket metal body 1. A first plastic layer 2 is injection molded on the front edge area of ​​the bracket metal body 1, so that a plastic groove 201 is formed in the middle of the first plastic layer 2; the plastic groove 201 is circular. The plastic groove 201 is used for subsequent filling with a transparent adhesive layer. The transparent adhesive layer can both waterproof the LED chip and prevent damage such as short circuits and corrosion caused by moisture, and will not obstruct the transmission of light emitted by the LED chip.

[0022] Furthermore, a first metal groove 101 is formed by stamping on the front side of the bracket metal body 1; a corresponding first protrusion 103 is formed on the back side of the bracket metal body 1; wherein, the first metal groove 101 is formed in the plastic groove 201. A plurality of second partition strips 7 are also provided in the plastic groove 201, the second partition strips 7 being used to divide the first metal groove 101 into several independent groove areas; an LED blue light chip is fixed in one of the groove areas, and phosphor is laid in the groove area corresponding to the LED blue light chip to form a phosphor layer, so that the LED blue light chip in this groove area can excite the phosphor to generate white light; while the remaining groove areas only have multi-color LED chips fixed, without phosphor being laid. Therefore, this utility model can both excite phosphor to emit white light by using an LED blue light chip and generate white light by mixing multiple primary color LED chips. In this way, different light emission methods can be selected for different scenarios with low and high color temperatures, thus solving the problem that LED lighting systems with phosphors have low energy efficiency at low color temperatures and LED lighting systems without phosphors have low energy efficiency at high color temperatures, thereby effectively improving the energy efficiency of LED lighting systems.

[0023] It should be noted that, since the second partition strip 7 separates the individual groove areas from each other, the phosphor will not overflow into the adjacent groove areas, thus not interfering with the light emission of the LED chips in the adjacent groove areas.

[0024] In this embodiment, the number of second partition strips 7 is set to two, so as to divide the first metal groove 101 into three independent groove areas. The LED blue light chip can be fixed and phosphor can be laid in the groove area in the middle position; while the multi-color LED chip can be fixed in the groove area at the edge. Alternatively, the LED blue light chip can be fixed and phosphor can be laid in the groove area at the edge, while the multi-color LED chip can be fixed in the groove area in the middle. Those skilled in the art can flexibly choose according to the actual situation, and the applicant does not make specific restrictions. In addition, those skilled in the art can also flexibly set the number of second partition strips 7 according to the actual situation, and the applicant does not make specific restrictions.

[0025] In some preferred embodiments, a second metal groove 102 is also stamped on the front side of the metal body 1 of the bracket; a multi-color LED chip is fixed in the second metal groove 102, and no second partition strip 7 is provided in the second metal groove 102 for separation. At least two first partition strips 6 are provided in the plastic groove 201; and the first metal groove 101 is located in the space enclosed by the two first partition strips 6 and the first plastic layer 2, and the two ends of the second partition strip 7 are connected to the first partition strips 6. In this way, the first partition strips 6 can prevent the phosphor in the first metal groove 101 from overflowing into the second metal groove 102, thereby not interfering with the light emission of the LED chip in the second metal groove 102.

[0026] It should be noted that for multi-color LED chips, the inner walls of the first metal groove 101 and the second metal groove 102 can reflect the light emitted by various primary color LED chips, thereby fully mixing the light emitted by the multi-color LED chips and improving the light mixing effect of the multi-color LED chips. Furthermore, since the first metal groove 101 and the second metal groove 102 restrict the light emission angle of the LED chips, they can act as light-focusing devices, improving the luminous efficacy of the LED chips. For blue LED chips used to excite phosphors, the first metal groove 101 facilitates the deposition of phosphors to form a phosphor layer. In addition, since the first protrusion 103 and the second protrusion 104 are used to contact the aluminum substrate of the lamp board, the good thermal conductivity between the metals allows the heat generated by the LED chips to be quickly transferred to the aluminum substrate, effectively improving the heat dissipation effect of the LED chips.

[0027] Optionally, a plastic connecting part 5 is injection molded within the plastic groove 201. The plastic connecting part 5 is integrally injection molded with the inner ring of the first plastic layer 2. Adhesive pins 4 are spaced apart on the plastic connecting part 5, and the height of the adhesive pins 4 is greater than the thickness of the plastic connecting part 5. During the subsequent filling of transparent adhesive, the adhesive pins 4 can improve the adhesion of the transparent adhesive layer, firmly fixing the transparent adhesive layer, thereby effectively preventing the transparent adhesive layer from falling off and enhancing the connection reliability of the transparent adhesive layer.

[0028] Optionally, a second plastic layer 3 is injection molded onto the back of the bracket metal body 1. The thickness of the second plastic layer 3 is equal to the thickness of the first protrusion 103 and the second protrusion 104, and the second plastic layer 3 is staggered from the first protrusion 103 and the second protrusion 104. By injection molding the first plastic layer 2 and the second plastic layer 3 onto the front and back of the bracket metal body 1 respectively, the waterproof and insulating effects of the bracket metal body 1 can be improved, while not affecting the light output of the LED chip on the front of the bracket metal body 1 or the heat dissipation of the first protrusion 103 and the second protrusion 104 on the back of the bracket metal body 1.

[0029] It should be noted that the first plastic layer 2, the second plastic layer 3, the plastic stud 4, the plastic connecting part 5, the first partition strip 6, and the second partition strip 7 are all made of nylon PPA material. During the injection molding process to obtain the first plastic layer 2 and the second plastic layer 3, the plastic connecting part 5, the plastic stud 4, the first partition strip 6, and the second partition strip 7 are simultaneously injection molded. The plastic connecting part 5, the plastic stud 4, the first partition strip 6, and the second partition strip 7 are all injection molded within the plastic groove 201.

[0030] The working principle of this utility model is as follows: First, a first metal groove 101 and a second metal groove 102 are stamped on the front side of the metal body 1 of the bracket, and a first protrusion 103 and a second protrusion 104 corresponding to the first metal groove 101 and the second metal groove 102 are formed on the back side of the metal body 1 of the bracket. Then, a first plastic layer 2, a second plastic layer 3, a glue nail 4, a plastic connecting part 5, a first partition strip 6 and a second partition strip 7 are injection molded on the metal body 1. Then, LED blue light chips or multi-color LED chips are fixed in some groove areas. The LED chip is electrically connected to its pins via wire bonding. Phosphor powder is laid in the recessed area of ​​the blue LED chip to form a phosphor layer. Finally, a transparent adhesive layer is filled into the plastic recess 201. The adhesive nails 4 can firmly fix the transparent adhesive layer, thereby effectively preventing the transparent adhesive layer from falling off and enhancing the connection reliability of the transparent adhesive layer. The transparent adhesive layer can not only play a waterproof role, preventing water from entering the area where the LED chip is located, avoiding damage such as short circuits and corrosion caused by water, but also will not obstruct the light emitted by the LED chip from being transmitted.
