Description

Technical Field

[0001] This utility model relates to the field of LED bulb technology, specifically to an embedded LED bulb. Background Technology

[0002] LED bulbs, as a new type of energy-saving lighting fixture to replace traditional incandescent bulbs, use LED chips internally and have many advantages, such as uniform light guidance, no flicker, no glare, no ultraviolet or infrared radiation, no harmful substances such as mercury, and recyclability. However, common LED bulbs are often completely exposed, which affects the overall aesthetics to some extent. Therefore, recessed LED bulbs have emerged. However, currently, recessed LED bulbs generally use threaded connections for fixing. When an LED bulb malfunctions and needs to be replaced, the disassembly process is extremely complicated, not only consuming a lot of time and effort, but also prone to danger during operation, making it difficult to meet actual usage needs. At the same time, existing recessed lighting fixtures also have problems such as complex structure leading to waste of raw materials, poor light efficiency, and poor heat dissipation performance. For example, some recessed downlights have many structural parts, and the lighting principle is to refract light through a reflector cup, concentrating the light in one direction, with only the opposite side receiving light. The beam angle is focused, which easily produces glare and causes visual fatigue; some LED downlights use reflectors to refract light, which reduces light efficiency, has a small light-receiving area, and a limited illumination angle.

[0030] The outer diameter of the return spring 14 is 11mm, which is 1mm larger than the inner diameter of the socket 10.

[0040] I. Installation Process and Principle

[0041] When installing the recessed LED bulb, first fix the lamp holder 1 in the preset position through the mounting holes on the back. Next, hold the LED bulb 3 and align the spiral connector 5 at its top with the internally threaded connecting cylinder 7 inside the mounting opening 6 of the lamp panel 2, and begin to rotate the LED bulb 3. Since the spiral connector 5 uses an E26 standard thread, which matches the thread of the internally threaded connecting cylinder 7, the spiral connector 5 gradually screws into the internally threaded connecting cylinder 7 as it rotates.

[0042] During the screwing of the spiral connector 5, the guide block 8 at its top and the triangular wedge 9 mounted at its top will enter between the two insert rods 9. The apex angle of the triangular wedge 9 is 60°, and the normal direction of the contact surface between the two inclined surfaces and the insert rods makes an angle of 45° with the axis of the insert rods. As the spiral connector 5 is continuously screwed in, the triangular wedge 9 will exert a pushing force on the two insert rods 9 to both sides. The arc surface design of the outer end of the insert rod 12 makes the pushing of the triangular wedge 9 smoother and reduces frictional resistance.

[0043] Under the thrust, the insertion rod 12 moves to both sides along the insertion port 10. The limiting ring plate 13 at the opposite end of the insertion rod 11 compresses the return spring 14 fitted outside the insertion rod 11, at which time the return spring 14 accumulates elastic potential energy. When the screw connector 5 is screwed into the appropriate position, the end of the insertion rod 12 is exactly aligned with the slots on both sides of the inner wall of the mounting port 6. Under the elastic restoring force of the return spring 14, the insertion rod 12 is inserted into the slot. The anti-slip texture on the inner wall of the slot increases the friction between the insertion rod and the slot, making the connection more stable. At the same time, the brass electrode contact at the top of the screw connector 5 contacts the corresponding contact at the bottom of the internal threaded connecting cylinder 7, completing the circuit connection.

[0044] II. Usage Process and Principle

[0045] After the LED bulb 3 is installed, the power is turned on. The current is transmitted to the LED chip inside the LED bulb 3 through the wires inside the lamp holder 1, the internal threaded connecting cylinder 7, and the electrode contacts of the spiral connecting seat 5. The LED chip emits light and realizes the lighting function.

[0046] During illumination, the LED bulb 3 generates heat, which is transferred through the bulb's housing to the heat dissipation cavity 15 inside the lampshade 4. The inner wall of the heat dissipation cavity 15 is anodized, improving heat dissipation performance. The heat is further transferred to the heat dissipation fins 16 installed in the mounting slot 17. The heat dissipation fins 16 are made of aluminum alloy, are triangular in shape, and the included angle between each pair of adjacent fins is 12°. The 30 evenly distributed heat dissipation fins greatly increase the contact area with air, accelerate heat dissipation, ensure that the LED bulb 3 operates at a suitable temperature, and extend its service life.

[0047] The lampshade 4 is made of high-transmittance PC material with a light transmittance of ≥90%, which can effectively transmit the light emitted by the LED chip. At the same time, the design of the lampshade 4 can protect the internal structure of the LED bulb 3.

[0048] III. Disassembly Process and Principles

[0049] When the LED bulb 3 needs to be replaced or repaired, rotate the LED bulb 3 in the reverse direction, and the spiral connecting seat 5 begins to unscrew from the internal thread connecting cylinder 7. As the spiral connecting seat 5 unscrews, the guide block 8 and the triangular wedge block 9 gradually disengage from the two insert rods 9, and the thrust on the insert rods disappears.

[0050] At this point, the compressed return spring 14 extends under the action of elastic restoring force, pushing the limiting ring plate 13 to move the insertion rod 12 inward. The end of the insertion rod 12 exits from the slot and returns to the inside of the socket 10. Continue to rotate the LED bulb 3 until the spiral connecting seat 5 is completely unscrewed from the internal thread connecting cylinder 7, and then the LED bulb 3 can be removed.

[0051] Throughout the entire operation, the outer diameter of the return spring 14 is larger than the inner diameter of the socket 10, ensuring that the return spring 14 will not enter the socket 10 and affect the normal movement of the insertion rod. The limiting ring plate 13 limits the return spring 14, ensuring that the return spring 14 can perform its elastic function normally. The coordinated cooperation between the components enables convenient installation, stable use, and easy disassembly of the embedded LED bulb.
