Description

Technical Field

[0001] This utility model relates to the field of negative ion purification lamp structure, specifically a square lamp with negative ion purification function. Background Technology

[0002] Currently, some lighting products on the market include negative ion modules for air purification or sterilization. Existing products are mainly low-power negative ion generators, with a power output not exceeding 1W and a negative corona voltage not exceeding 6000V, achieving only localized purification effects. To achieve whole-house purification, the negative ion output corona voltage needs to be between 10000-25000V, with a power output typically between 3-8W. Higher negative ion output corona voltage generates greater high-voltage static electricity, which can cause metal electrical components to discharge to each other, damaging conductors. Utility Model Content

[0003] The purpose of this invention is to provide a square lamp with negative ion purification function to solve the problem of static electricity affecting the use of existing negative ion lamps.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a square lamp with negative ion purification function, comprising: The reflective housing contains LED lights and a circuit board. A front cover is connected to a reflective rear shell. The front cover includes an electrostatic eliminator made of conductive material and connected to a first grounding wire. The negative ion emitter has a self-reflecting housing that extends towards the front cover. The control housing is connected to the reflective housing and has multiple symmetrically distributed cavities inside. The central cavity houses the power controller, and the side cavities house the negative ion generators. The negative ion generators include a second grounding wire, and the power controller includes a third grounding wire. The second grounding wire, the first grounding wire, and the third grounding wire converge to form a total grounding wire. The reflective shell is made of non-metallic material.

[0005] As a further improvement to the above technical solution: The front cover includes corner pieces, and a plurality of static eliminators are connected to the corner pieces, with a conductor connecting the plurality of static eliminators.

[0006] The circuit board is a ceramic circuit board.

[0007] The cavity is equipped with a completely covered glue layer to encapsulate the negative ion generator and the power controller.

[0008] The negative ion emitter includes a discharge needle tip and a concentrator cup. The discharge needle tip is located at the center of the concentrator cup, and a grid is provided on the top surface of the concentrator cup. The discharge needle tip does not protrude from the top surface of the grid.

[0009] A light guide plate and a crystallization plate are disposed between the reflective housing and the front cover, and the concentrating cup is disposed through the light guide plate and the crystallization plate.

[0010] The negative ion generator is connected to a pulse control unit, which is used to control the intermittent operation of the negative ion generator.

[0011] The back of the reflective housing is provided with a reinforcing rib, and the side of the reinforcing rib is provided with a mounting buckle.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The conductive material electrostatic eliminator installed on the front cover, effectively grounded through the first grounding wire, serves two purposes: dust collection and eliminating high-voltage static electricity generated by the high-power negative ion generator. The ceramic material protects the conductors and prevents static electricity from spreading to the internal circuitry and affecting the equipment's lifespan. A pulsed negative ion generator is employed; intermittent discharge reduces static electricity generation and facilitates its elimination. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating orientation or position, are based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 4 As shown, the square lamp with negative ion purification function in this embodiment includes: The reflective housing 1 contains an LED light 11 and a circuit board 12. The front cover 2 is connected to the reflective housing 1. The front cover 2 includes an electrostatic eliminator 3, which is made of conductive material and is connected to a first grounding wire. In one embodiment, the electrostatic eliminator 3 is the front cover 2 itself. If the front cover 2 is made of conductive material, then there is no need to design an electrostatic eliminator 3 separately. If the front cover 2 is made of non-conductive material, then an electrostatic eliminator 3 needs to be designed separately and installed on the surface of the front cover 2.

[0020] The front cover 2 includes a U-shaped part and a sealing part I, both of which have a groove-shaped cross section. The end of the reflective housing 1 is provided with a sheet-like structure that matches the groove. During installation, the reflective housing 1 is slid into the U-shaped part, and then the sealing part I is connected to the U-shaped part by screws to complete the assembly.

[0021] The negative ion emitter 4 extends from the self-reflecting housing 1 to the front cover 2; The control housing 5 is connected to the reflective housing 1 and has multiple symmetrically distributed cavities inside. The central cavity houses the power controller 6, and the side cavities house the negative ion generator 7. The negative ion generator 7 includes a second grounding wire, and the power controller 6 includes a third grounding wire. The second grounding wire, the first grounding wire, and the third grounding wire are combined to form a total grounding wire. The reflective housing 1 is made of a non-metallic material. Considering material costs, plastic is usually used as the material for the reflective housing 1.

[0022] like Figure 5 As shown, the front cover 2 includes corner pieces 21, and multiple static eliminators 3 are connected to the corner pieces 21. Conductors are connected between the multiple static eliminators 3. Here, the front cover 2 includes several slotted conductive parts (i.e., static eliminators, and several slotted conductive parts are directly connected to wires), and the slotted conductive parts are inserted into the corner pieces 21.

[0023] Circuit board 12 is a ceramic circuit board. Using a ceramic circuit board effectively prevents mutual discharge between electrical components, thus avoiding impact on lifespan. The excellent insulation of the ceramic circuit board makes it difficult for external static electricity to be conducted to the internal circuitry, thereby preventing electrostatic interference or damage to the internal circuitry. The ceramic used here is typically alumina, zirconium oxide, magnesium oxide, or other special ceramics.

[0024] The cavity is equipped with a fully covering potting layer to encapsulate the negative ion generator 7 and the power controller 6. The potting layer is typically made of resin adhesive. This prevents static electricity from affecting the electrical components within the cavity.

[0025] The negative ion emitter 4 includes a discharge needle tip 41 and a concentrator cup 42. The discharge needle tip 41 is located at the center of the concentrator cup 42, and a grid 43 is provided on the top surface of the concentrator cup 42. The discharge needle tip 41 does not protrude from the top surface of the grid 43. The spacing of the grid 43 should be less than 1.1 cm to prevent accidental contact with the discharge needle tip. The main function of the concentrator cup 42 is to concentrate the negative ions generated by the discharge needle tip downwards, preventing them from diffusing to the sides and improving the concentration and directionality of the released negative ions; the grid prevents accidental contact with the discharge needle tip, ensuring safe use.

[0026] A light guide plate 8 and a crystallizing plate 9 are disposed between the reflective housing 1 and the front cover 2, and a concentrating cup 42 is disposed through the light guide plate 8 and the crystallizing plate 9. Since the function of the electrostatic eliminator causes dust to be collected on the surface of the lamp body, the crystallizing plate 9 is used. The crystallizing plate 9 is made of UV-cured resin material, which has a certain degree of dirt resistance and wear resistance, making it easy to wipe the surface of the lamp and preventing dust from affecting the lighting effect.

[0027] The negative ion generator 7 is connected to a pulse control unit, which controls its intermittent operation. Simply put, the pulse control unit operates intermittently; during the period when discharge stops, the electric field strength decreases, slowing down the accumulation of charge and thus reducing static electricity generation. This avoids the drawbacks of continuous high voltage, reducing static electricity generation at the source and inhibiting static buildup. The intermittent period is typically 30-60 minutes on and 0.5-1 minute off.

[0028] The back of the reflective housing 1 is provided with a reinforcing rib 13, and the side of the reinforcing rib 13 is provided with a mounting buckle 14.

[0029] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics of the solutions is not described in detail here. For those skilled in the art, this utility model is obviously not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
