Technical Field

[0001] The utility model relates to the technical field of LED lamps, and in particular to a novel LED lamp bead. Background Art

[0002] LED is the abbreviation of light emitting diode. Its basic structure is a piece of electroluminescent semiconductor material placed on a rack with leads, and then sealed with epoxy resin on all sides to protect the internal core wire.

[0003] LED light-emitting chip is the core component of LED lamp, which refers to PN junction. Its main function is to convert electrical energy into light energy. With the rapid development of science and technology, LED has entered our production and life. LED light has many advantages such as high color gamut, high brightness, long life, energy saving and environmental protection, and real-time color controllability. Since the beginning of the 21st century, light source technology has developed rapidly, and new technologies and new products have been continuously introduced. LED light has become the mainstream of the market. Compared with traditional CCFL backlight sources, LED light has many advantages such as high color gamut, high brightness, long life, energy saving and environmental protection, and real-time color controllability. In particular, the high color gamut LED backlight makes the screens of electronic products such as TVs, mobile phones, and tablets that use it have more vivid colors and higher color reproduction.

[0004] However, existing LED lamp beads still have some problems, such as insufficient lighting effect and uneven light output. Utility Model Content

[0005] The purpose of the utility model is to provide a new type of LED lamp bead to solve the problem of uneven light emission of the above-mentioned lamp bead.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is to provide a new type of LED lamp bead, including a lamp frame, a lamp bead chip and a welding wire. The lamp bead chip is arranged on the lamp frame, and the welding wire connects the lamp bead chip and the lamp frame to connect the circuit. There are at least three lamp bead chips, and multiple lamp bead chips are arranged around the center of the lamp frame. The distance between each lamp bead chip and the center of the lamp frame is the same.

[0007] Furthermore, the distance between any two adjacent lamp bead chips is the same.

[0009] Furthermore, the lamp bead chip is packaged on the lamp frame, and the lens is buckled on the lamp frame, and the lens converges the light emitted by the lamp bead chip.

[0010] Furthermore, a fluorescent layer is filled between the lens and the lamp bead chip, and the fluorescent layer is filled with a mixture of diffusion powder and fluorescent glue.

[0011] Furthermore, the lamp bead chip is a luminous semiconductor material, including a PN junction. By connecting the welding wire, the electric energy of the power supply is transmitted to the lamp bead chip through the lamp holder, and the PN junction is stimulated to emit light.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Reference Figure 1 A new type of LED lamp bead provided as an embodiment of the utility model includes a lamp frame 1, a lamp bead chip 2 and a welding wire 3. The lamp bead chip 2 is arranged on the lamp frame 1. The welding wire 3 connects the lamp bead chip 2 and the lamp frame 1 to connect the circuit. There are at least three lamp bead chips 2, and multiple lamp bead chips 2 are arranged around the center 11 of the lamp frame. The distance between each lamp bead chip 2 and the center 11 of the lamp frame is the same.

[0027] In the present application, multiple lamp beads 2 are arranged around the center 11 of the lamp frame, and each lamp bead chip 2 is at the same distance from the center 11 of the lamp frame. The light output angle and luminous flux of each point are guaranteed to be uniform, and the light output is more uniform after matching the lens, which can well solve the problem of uneven light spots and rib patterns of products such as advertising light boxes, and improve the display effect of light.

[0028] Specifically, in order to further increase the uniformity of light emission, it is necessary to ensure that the distance between any two adjacent lamp bead chips 2 is the same. In this embodiment, there are three lamp bead chips 2, and the three lamp bead chips 2 are connected in sequence and enclosed to form an equilateral triangle. The use of three lamp bead chips 2 can meet the minimum uniform light emission effect and save the overall cost of the lamp beads. The welding wire 3 is used to connect the welding pad of the lamp bead chip 2 and the lamp holder 1 so that the circuit can be turned on; in this embodiment, the welding wire 3 is a gold wire with a diameter of 0.8 mil or 1.0 mil. The heat is transferred to the lamp holder 1 in time through the gold wire, and the heat can be dissipated in time. In addition, the gold wire has stronger stretchability and is not prone to dead lamps due to the breakage of the gold wire.

[0029] Furthermore, the novel LED lamp bead also includes a lens. The lamp bead chip 2 is packaged on the lamp frame 1 , and the lens is buckled on the lamp frame 1 . The lens converges the light emitted by the lamp bead chip 2 .

[0030] Furthermore, a fluorescent layer is filled between the lens and the lamp bead chip 2, and the fluorescent layer is filled with a mixture of diffusion powder and fluorescent glue. In the present application, after the lamp bead chip 2 emits light, the fluorescent layer can be excited and the light spot can be removed, making the light output more uniform.

[0031] Specifically, the lamp bead chip 2 is a luminous semiconductor material, including a PN junction. By connecting the welding wire 3, the power supply energy is transmitted to the lamp bead chip 2 through the lamp holder 1, and the PN junction is stimulated to emit light. The lamp bead chip 2 emits light to stimulate the fluorescent layer to emit light. In this embodiment, the lamp bead chip 2 adopts a blue light chip, and the fluorescent layer adopts diffusion powder and fluorescent glue. After sufficient stirring and mixing, it is evenly distributed and then filled into the fluorescent layer. The fluorescent layer is an orange fluorescent powder layer. The lamp holder 1 is used to fix the lamp bead chip 2 and carry the fluorescent powder layer, and the current is introduced into the chip to release the heat generated by the chip. The lamp holder 1 is formed by electroplating the lamp holder 1 material. The lamp holder 1 is composed of five layers from the inside to the outside, namely, material, copper, nickel, copper, and silver. The lamp holder 1 can be a cup holder or a flat-head holder. The blue light chip is mainly used for luminescence and is composed of luminous semiconductor materials. For example, it may be composed of materials such as gallium phosphide (GaP), gallium aluminum arsenide (GaAlAs) or gallium arsenide (GaAs), gallium nitride (GaN), etc., and its internal structure has unidirectional conductivity.

[0032] The welding wire 3 allows the power of the power supply to be transmitted to the blue light chip through the bracket, stimulating the PN junction to emit light, and the blue light chip emits light to stimulate the fluorescent layer, thereby emitting yellow light. Specifically, when the blue light chip is powered on, the PN junction in the chip converts the power into 450-460NM light energy, allowing the light energy in this band to pass through the orange phosphor layer and emit yellow light, thereby achieving the required yellow light. It has the same function as the traditional yellow light chip, the cost is lower than that of the yellow light chip, and because the voltage is consistent with the voltage of the blue light lamp bead, it is obviously easier to design the circuit than the traditional yellow light chip.

[0033] In the present application, multiple lamp beads 2 are arranged around the center 11 of the lamp frame, and each lamp bead chip 2 is at the same distance from the center 11 of the lamp frame. The light output angle and luminous flux of each point are guaranteed to be uniform, and the light output is more uniform after matching the lens, which can well solve the problem of uneven light spots and rib patterns of products such as advertising light boxes, and improve the display effect of light.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
