Description

Technical Field

[0001] The utility model relates to a lighting device, in particular to a lighting lamp assembly for household appliances. Background Art

[0002] In modern home life and home appliance applications, lighting devices play a vital role, not only providing necessary lighting for use at night or in low light conditions, but also enhancing the aesthetics and user experience of the product. However, traditional lighting solutions, especially the widely used tungsten filament bulbs, have significant deficiencies in many aspects.

[0003] First of all, the working principle of tungsten filament bulbs is to pass current through the tungsten filament to heat it to a high temperature to emit light. In this process, a lot of energy is lost in the form of heat, resulting in low lighting efficiency. This inefficient energy conversion not only increases energy consumption, but also means that tungsten filament bulbs will generate a lot of heat under long-term use, which may pose a threat to the safety and stability of household appliances.

[0004] Secondly, due to the characteristics of its working principle, tungsten filaments are very easy to break in physical vibration or temperature changes, which greatly reduces the reliability of tungsten filament bulbs during transportation and use. In home appliances and furniture products, this low reliability means higher repair and replacement costs, reducing the overall user satisfaction.

[0005] In addition, from an environmental perspective, there are potential environmental risks in the production and disposal of tungsten filament bulbs, such as the use of heavy metals and other harmful substances, which increases the burden on the environment.

[0006] In recent years, with the development of LED technology, LED bulbs have gradually become the new favorite of the lighting market due to their high efficiency, long life and environmental protection. LED bulbs generate light through semiconductor materials, with high conversion efficiency, low heat generation, and much lower sensitivity to vibration and temperature changes than traditional tungsten filament bulbs, which improves product reliability and service life. However, despite the obvious advantages of LED technology, existing LED lighting solutions still face challenges in cost and design complexity.

[0007] For example, patent CN102280358A uses tungsten filament bulbs, which have high energy consumption and are prone to broken filaments; patents CN206036828U, CN209309950U, CN212537545U, and CN212961115U also use LED filaments, but the product structure is complex, using glass bulbs, glass filament brackets, vacuum bulbs, etc. The production process must be high temperature, vacuum, and inert gas filling, resulting in high product costs. Patent CN216844313U uses traditional LED lamp beads and a switch step-down power supply device. The light-emitting range is limited and the product cost is high, so it is necessary to make further improvements. Utility Model Content

[0033] The present invention is further described in detail below with reference to the accompanying drawings. An LED lighting lamp, characterized in that it comprises:

[0034] A lamp holder 1, the top of which is covered with a lampshade 2, which is made of a transparent material and has a hollow shell structure;

[0035] The lamp holder 1 is hollow inside to form a receiving cavity 3, a fixing plate 4 is installed in the receiving cavity 3, a plurality of positioning grooves 41 are arranged on the outer circle of the fixing plate 4, and correspondingly, a corresponding positioning column 31 is arranged in the receiving cavity 3. After the fixing plate 4 is installed in the receiving cavity 3, the hot-melt positioning column 31 fixes the fixing plate 4 in the receiving cavity 3;

[0036] The fixing plate 4 is provided with a first electrode plate 5 and a second electrode plate 6 through its upper and lower end surfaces, and the power lines are respectively connected to the first electrode plate 5 and the second electrode plate 6 at the lower part of the fixing plate 4;

[0037] The lamp also includes an LED light-emitting component located inside the lampshade 2 , a voltage-dropping resistor 7 connected in series with the LED light-emitting component, and then connected to a first electrode sheet 5 and a second electrode sheet 6 on the upper portion of the fixing sheet 4 .

[0038] Specifically: the positioning groove 41 is two semicircular notches arranged on the outer circle of the fixing plate 4, and the two notches are not arranged with equal diameters. Correspondingly, two positioning columns 31 are also arranged, and their diameters correspond to the diameters of the two semicircular notches, which plays a role in limiting and preventing errors when installing the fixing plate.

[0039] Specifically, the accommodating cavity 3 is a circular through hole penetrating the upper and lower end surfaces of the lamp holder 1 , a positioning ring 11 is provided on the hole wall protruding from the circular through hole, and the top of the fixing plate 4 is pressed against the bottom of the positioning ring 11 for installation.

[0040] Specifically: a connection area 12 is arranged on the inner hole of the positioning ring 11, and the connection area 12 is arranged tangent to the inner hole of the positioning ring 11. The positioning column 31 is arranged on the lower end surface of the connection area 12 and extends downward.

[0041] Specifically: the first electrode sheet 5 and the second electrode sheet 6 are bent with folded edges 71 on both sides, and correspondingly, the fixing sheet 4 is provided with a mounting groove 42 penetrating the upper and lower end surfaces thereof, the first electrode sheet 5 and the second electrode sheet 6 are inserted and installed in the mounting groove 42, and the folded edges 71 are elastically supported in the slot holes of the mounting groove 42. The elastically supported structure makes the electrode sheet and the mounting groove more firm and reliable after being installed.

[0042] Specifically: the side walls of the first electrode sheet 5 and the second electrode sheet 6 are provided with anti-slip undercuts 8, and correspondingly, the groove wall of the installation groove 42 is provided with an anti-slip groove 43. After the first electrode sheet 5 and the second electrode sheet 6 are installed, the anti-slip undercuts 8 are inserted into the anti-slip groove 43 for fixation. Compared with the traditional in-mold injection molding method, the electrode sheet is installed by an undercut insertion method in this case, thereby reducing the difficulty of mold production. At the same time, the simple insertion method allows the electrode sheet to be assembled by automated mechanical equipment, thereby reducing dependence on manual labor.

[0043] Specifically, the anti-dropping buckle 8 on the first electrode sheet 5 and the anti-dropping buckle 8 on the second electrode sheet 6 are arranged in a staggered manner, and correspondingly, the anti-dropping groove 43 in the installation groove 42 is arranged in a position corresponding to the anti-dropping buckle 8. The staggered arrangement facilitates the correct installation of the electrode sheet and avoids the electrode sheet being installed incorrectly and affecting normal use.

[0044] Specifically: the LED light-emitting component includes a full-wave rectifier bridge composed of four luminous PN junctions, and the direct current output from the output end of the rectifier bridge is used for several main light-emitting PN junctions; one input end of the full-wave rectifier bridge is connected in series with a step-down resistor 7 and then connected to the first electrode sheet 5, and the other input end is connected to the second electrode sheet 6.

[0045] Specifically: the full-wave rectifier bridge and the main light-emitting PN junction are packaged in the LED light-emitting component 9.

[0046] Specifically: one end of the step-down resistor 7 is vertically mounted and fixed on the top of the first electrode sheet 5, one end of the LED light-emitting component 9 is vertically mounted on the top of the second electrode sheet 6, and the other end of the step-down resistor 7 is connected to the other end of the LED light-emitting component 9 through a "U"-shaped wire.

[0047] Working principle: The structure of the utility model consists of three parts: 1. Transparent lampshade, which is made of transparent plastic material, glass, or other transparent materials.

[0048] LED filament assembly part, this part uses a ceramic substrate with silk screen printed conductive circuits and press Figure 4 The circuit diagram layout welds multiple PN light-emitting diodes (15 to 40 light-emitting diodes) to form a light bar. Two conductive leads are welded to the ceramic substrates at both ends of the light bar to form a light-emitting module. The ceramic substrates of the welded light-emitting diodes are covered with silicone material or processed with other insulating materials for protection.

[0049] The LED filament assembly part has a full-wave rectifier circuit composed of four luminous PN junctions. The rectified DC power supplies several luminous PN junctions. The power supply circuit can be set to 220V AC power supply or 110V AC power supply or other voltage power supply by adjusting the resistance value, PN junction voltage and the number of PN junctions. Therefore, it has the advantage of wide voltage use, which is suitable for use in various regions and improves its scope of application.

[0050] Among them, in order to fix the LED filament assembly, the LED filament assembly and the step-down resistor are connected and welded together in this case, and bent into a "U" shape structure, and the two ends are respectively welded to the first electrode sheet and the second electrode sheet. The first electrode sheet and the second electrode sheet are fixed on the fixing sheet, which supports and fixes the filament assembly and the step-down resistor to form an integral wick assembly, which is convenient for automated assembly.

[0051] The filament assembly, the voltage-dropping resistor, the first electrode sheet and the second electrode sheet form a complete LED lamp power supply circuit. When the terminal plugs on the first electrode sheet and the second electrode sheet are connected to an external power source, the LED lamp can be lit.

[0052] The lampshade is preferably a transparent plastic shell member. After the lampshade is sleeved on the connecting seat provided on the upper end surface of the lamp holder, the transparent lamp shell and the connecting seat are bonded into one by ultrasonic welding or other means.

[0053] The lamp holder is made of plastic injection molding or other insulating materials, wherein the LED filament assembly and the voltage-dropping resistor pass through the accommodating cavity on the lamp holder and enter the interior of the bulb assembly, the inner surface of the fixing plate is buckled on the positioning ring 11 of the lamp holder, and the two positioning posts cooperate with the positioning grooves on the fixing plate. After the fixing plate is buckled, the positioning posts on the lamp holder are heated and melted to form the lamp holder and the wick assembly into one. Since the hot-melted positioning posts are fixed to the fixing plate as one, loosening between the two is effectively avoided, thereby ensuring the connection strength.

[0054] Compared with traditional technology, in this case, the diode characteristics of multiple PN junctions of LEDs are used to form a full-wave rectifier circuit to form direct current, which is then stepped down by resistance to replace traditional rectifier board modules and high-power DC LED lamp beads. At the same time, the double-sided light-emitting technology of the LED filament circuit is used to achieve 360-degree light emission of the LED filament, thereby meeting the performance requirements of the bulb and greatly reducing the cost of the product in principle.

[0055] In addition, by optimizing the product structure plan and the product production process, structural parts such as the lamp holder, filament bracket, vacuum bulb, and high-temperature glass bulb were removed, transparent and renewable plastic parts were used to replace difficult-to-recycle glass parts, and thermoplastic plastics were used to replace non-renewable and non-environmentally friendly thermosetting plastics, thereby greatly reducing the structural cost of the product.

[0056] In addition, by optimizing the product structure plan and taking into account the automated production technology, the production process of the product is optimized. First, the number of working steps is reduced, and second, automated equipment is used to replace manual labor; the manufacturing cost of the product is greatly reduced, so it can be widely promoted and used.

[0057] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
