Description

Technical Field

[0001] This utility model relates to the field of LED point light source technology, specifically an externally controlled LED point light source. Background Technology

[0002] LED point light sources are a new type of decorative lighting, supplementing linear light sources and floodlighting. They are intelligent lights that can replace displays of a certain size by achieving a point-to-surface effect through pixel color mixing. Pixel pitch: the distance from the center of one pixel to the center of another, also known as "P-numbers" (e.g., P3, P6). Point distance reflects pixel density, and both point distance and pixel density are physical characteristics of a display screen. Information capacity is a unit of measurement for the amount of information that can be displayed per unit area of ​​pixel density. A smaller point distance indicates higher pixel density, more information can be displayed per unit area at once, and a closer viewing distance is suitable.

[0003] The greater the pixel pitch, the lower the pixel density, the less information can be displayed per unit area at once, and the farther the suitable viewing distance. LED, or Light Emitting Diode, is a light-emitting device made using semiconductor homogeneous PN junctions, heterogeneous PN junctions, metal-semiconductor (MS) junctions, and metal-insulator-semiconductor (MIS) junctions. Its working principle and some electrical characteristics are the same as those of a general crystal diode, but the crystal material used is different. LEDs include different types such as visible light, invisible light, and laser; visible light LEDs are the most common in daily life. The color of light emitted by an LED depends on the materials used, and currently, there are many colors available, including yellow, green, red, orange, blue, purple, cyan, white, and full color. They can be made into various shapes such as rectangles and circles. LEDs possess advantages such as long lifespan, small size and light weight, low power consumption (energy saving), and low cost. They also feature low operating voltage, high luminous efficiency, extremely short light response time, wide operating temperature range, pure light color, robust structure (impact and vibration resistant), and stable and reliable performance, making them highly popular. Because LEDs are close to point light sources, lamp design is relatively convenient. However, when used for large-area displays, the current and power consumption are relatively high. LEDs are commonly used in indicator lights, digital tubes, display panels, and other display devices in electronic equipment, as well as optocouplers. They are also frequently used in optical communication and in the decoration of building outlines, amusement parks, billboards, streets, stages, and other venues.

[0004] Compared to traditional light sources, LED light sources are smaller and lighter, allowing them to be manufactured into various shapes, facilitating the placement and design of various lighting fixtures and equipment. They are highly adaptable and have a wide range of applications. Because LED light sources do not require the addition of mercury during production, they do not cause mercury pollution after disposal, and their waste is almost entirely recyclable, saving resources and protecting the environment. LED light sources can be driven by low-voltage DC power, typically between 6 and 24V, resulting in good safety performance, making them particularly suitable for public places. Furthermore, under favorable environmental conditions, LED light sources exhibit less light decay and a longer lifespan than traditional light sources; even frequent switching does not affect their lifespan. The basic structure of an LED light source consists of an electroluminescent semiconductor material placed on a leaded frame and sealed with epoxy resin. Structurally, it lacks a glass casing and does not require a vacuum or specific gas filling inside the tube like incandescent or fluorescent lamps. Therefore, LED light sources have excellent shock and impact resistance, bringing convenience to all aspects of their production, transportation, and use. By changing the current, chemically modifying, and mixing monochromatic light, LED light sources can achieve emission and color changing in various colors within the visible light spectrum. Even white LEDs can be manufactured into light sources with various color temperatures. Therefore, they have significant advantages in indoor decorative lighting and landscape lighting. Currently, externally controlled LED point light sources are not convenient to install and disassemble, and their central portion is also prone to bending and deformation due to gravity.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an externally controlled LED point light source, comprising an externally controlled LED point light source LED bead body, a plastic LED point light source mounting strip on the upper surface of the externally controlled LED point light source LED bead body, the lower surface of the plastic LED point light source mounting strip overlapping the lower surface of the plastic LED point light source mounting strip, an installation groove on the upper surface of the externally controlled LED point light source LED bead body, an LED bead mounting plate inside the installation groove, the top of the LED bead mounting plate being fixedly connected to the lower surface of the plastic LED point light source mounting strip, a blocking groove for a blocking rod being formed on the right inner wall of the installation groove, a blocking rod being inserted into the blocking groove, the left end of the blocking rod being fixedly connected to the right side of the LED bead mounting plate, an opening communicating with the lower surface on the upper surface of the plastic LED point light source mounting strip, and mounting screws inside the plastic LED point light source mounting strip for mounting the externally controlled LED point light source... The LED chip body is attached to the lower surface of the plastic LED point light source mounting strip, allowing each LED chip mounting plate to enter the corresponding mounting groove. Then, the four externally controlled LED point light source chip bodies are pushed to the left, causing the blocking rod on the right side of the chip mounting plate to engage with the blocking groove. Next, the chip mounting plate is positioned using a limiting block inserted into the mounting groove. Finally, the adhesive layer is applied to the mounting area, and the mounting screws are tightened upwards to complete the installation of the externally controlled LED point light source. For installation and disassembly, unscrew the mounting screws, pull the plastic LED point light source mounting strip upwards to separate the adhesive layer from the mounting area, then pull the retaining block removal handle upwards. The retaining block removal handle will move the LED bead mounting plate out of the mounting groove using the limiting retaining block. Then pull the external control LED point light source LED bead body to the right to separate the blocking rod from the inside of the blocking groove. Finally, pull the external control LED point light source LED bead body downwards to complete the disassembly.

[0008] Furthermore, the number of externally controlled LED point light source light-emitting lamp beads is four, and the four externally controlled LED point light source light-emitting lamp beads are electrically connected to each other through flame-retardant wires.

[0009] Furthermore, the mounting groove is provided with a limiting support block for the lamp bead mounting plate. The left side of the limiting support block overlaps with the left inner wall of the mounting groove, and the right side of the limiting support block overlaps with the left side of the lamp bead mounting plate.

[0010] Furthermore, the upper surface of the lamp bead mounting plate is fixedly connected to the retaining block with a retaining block removal handle.

[0011] Furthermore, the upper surface of the plastic LED point light source mounting strip is bonded with an adhesive layer.

[0012] Furthermore, the upper surface of each of the four externally controlled LED point light source lamp beads is provided with a mounting groove.

[0013] Furthermore, the abutment block detachment handle is located inside the opening.

[0014] This invention provides an externally controlled LED point light source. It has the following beneficial effects:

[0015] This externally controlled LED point light source, through the combination of a plastic LED point light source mounting strip, mounting groove, LED bead mounting plate, blocking rod with a blocking groove, blocking rod, LED bead mounting plate limiting support block, opening, and a pull handle for disassembling and assembling the support block, allows for very convenient installation and disassembly of the point light source, making the installation and disassembly work much faster. The setting of the self-adhesive layer can limit the middle of the point light source, preventing the point light source from completely deforming downwards due to its own weight. This solves the problem that current externally controlled LED point light sources are not convenient to install and disassemble, and that the middle part is prone to bending and deforming downwards due to gravity.
