Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of LED brackets, and specifically relates to an LED bracket. Background Art
[0002] In existing LED brackets, a small concave groove is made at the joint surface between the plastic and the bracket copper material by physical stamping. Due to the limitation of the stamping method, the depth of the groove is shallow (usually less than 0.1mm) to strengthen the bonding between the bracket plastic and the copper material and improve the airtightness of the LED.
[0003] However, the groove at the joint surface between the bracket plastic and the bracket copper of the existing LED bracket is shallow, and the adhesion between the bracket plastic and the bracket copper is low. When the LED use environment changes, the internal heat expansion and contraction of the LED causes the bracket plastic and the bracket copper to be easily peeled off, and the air tightness of the LED bracket is reduced, allowing water vapor, oxygen, etc. to enter the interior of the LED, causing the LED brightness to decay, and even causing failure. External water vapor and oxygen enter the interior of the LED along the joint surface between the bracket plastic and the bracket copper. The penetration path of the existing LED bracket is short and direct, which further leads to poor air tightness of the LED bracket. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.
[0023] In one embodiment of the present invention, Figure 1 As shown, an LED bracket comprises a substrate 1 and a reflector cup 2 arranged on the substrate 1, wherein the reflector cup 2 is concave and inclined to form a chip receiving groove, wherein a plurality of LED chips 3 are arranged in the chip receiving groove, wherein the plurality of LED chips 3 are connected to the substrate 1 through connecting wires 4, and wherein the chip receiving groove is filled with fluorescent glue 5;
[0024] Specifically, in the present embodiment, the reflective cup 2 is a bowl-shaped structure, which is concavely arranged to form a chip receiving groove for installing the LED chip 3. The LED chip 3 is fixed on the substrate 1, and the LED chip 3 is connected to the substrate 1 through a connecting wire 4. It should be noted that a dividing groove is provided on the substrate 1, which divides the substrate 1 into positive and negative poles, and the LED chip 3 is respectively connected to the positive and negative poles through the connecting wire 4. At the same time, the chip receiving groove is filled with fluorescent glue 5 to improve the overall luminous performance of the LED bracket.
[0025] The substrate 1 is symmetrically provided with a plurality of spaced bosses 6, the tops of the bosses 6 are serrated, and the bosses 6 and the reflector cups 2 are nested with each other;
[0026] Specifically, a plurality of spaced-apart bosses 6 are provided on the substrate 1, i.e., a certain gap is left between two adjacent bosses 6. Through the gap and the plurality of bosses 6, the penetration path of water vapor and oxygen can be greatly lengthened, thereby further improving the air tightness of the LED bracket. At the same time, when viewed from above, the bosses 6 are in a relatively U-shaped structure, thereby wrapping the chip accommodating groove, thereby improving the air tightness of the LED bracket. The top of the bosses 6 are in a serrated shape, and at the same time, the bosses 6 can improve the connection tightness and bonding strength between the substrate 1 and the reflective cup 2.
[0027] In this embodiment, along the direction from both sides of the substrate 1 to the middle of the substrate 1, the heights of the plurality of bosses 6 decrease in sequence;
[0028] Specifically, the height of the boss 6 decreases gradually from the two sides to the middle. Since the reflector cup 2 is a bowl-shaped structure, in order to fit the side wall shape of the reflector cup 2, the height of the boss 6 is designed to decrease gradually. At the same time, the boss 6 with a decreasing height can effectively block the entry of water vapor and oxygen, thereby improving the air tightness of the LED bracket.
[0029] In this embodiment, the substrate 1 and the boss 6 are both made of copper material.
[0030] In this embodiment, the reflective cup 2 is made of plastic material.
[0031] In this embodiment, the substrate 1 and the boss 6 are integrally formed;
[0032] Specifically, the integrally formed substrate 1 and boss 6 can further enhance the bonding strength between the substrate 1 and the reflective cup 2 , thereby improving the air tightness of the LED bracket.
[0033] In this embodiment, the height of the boss 6 is 0.2 mm to 0.3 mm.
[0034] At the same time, the packaging method of the LED bracket is as follows: on the substrate 1, several bosses 6 are designed in sequence, and barrier glue is set. At the remaining positions, the excess copper material is etched away with etching liquid in batches to obtain the boss 6 structure, and then the injection mold and the substrate 1 are closed to form a cavity; plastic is filled in the cavity, heated and cured to obtain a reflector cup 2; the excess copper sheet on the edge of the substrate 1 is cut off to form a single LED bracket, and the LED chip 3 is fixed in the middle position of the bracket; the LED chip 3 and the substrate 1 are welded to conduct electricity, and the fluorescent glue 5 is filled in the bracket bowl, and baked and cured to complete the packaging
[0035] In summary, the LED bracket in the above-mentioned embodiments of the utility model, the present application improves the bonding force between the substrate 1 and the reflector cup 2 by setting a plurality of spaced apart bosses 6, and the bosses 6 and the reflector cup 2 are nested with each other and the top of the bosses 6 is serrated, thereby improving the air tightness of the LED bracket. At the same time, the bosses 6 can greatly lengthen the penetration path of water vapor and oxygen, further improving the air tightness of the LED bracket.
