[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0022] Embodiment

[0023] As shown in Figures 1 to 4 , a three-proof bulb lamp includes a lamp holder 1 and a bulb lampshade 2. In this embodiment, both the lamp holder and the bulb lampshade are conventional structural bodies of the prior art. The lamp holder is used to connect the lamp head, and the bulb lampshade is a plastic lampshade or an acrylic lampshade, mainly for outward irradiation.

[0024] During the actual application process, a cylindrical light source holder 3 is provided between the lamp holder and the bulb lampshade. A circular plate 4 is integrally formed on the bottom surface of the cylindrical light source holder. During installation, a light source board is fixed to the bottom surface of the circular plate. The light source board is a conventional structure of the prior art and is only simply applied, so it is not described in detail and is only briefly explained, which does not affect the understanding and implementation by technicians. And in this embodiment, an upper snap ring 5 is provided at the lower part of the inner wall of the lamp holder, and a lower snap ring 6 is provided at the upper part of the inner wall of the bulb lampshade. Snap ring grooves 7 are provided on both the upper and lower parts of the outer wall of the cylindrical light source holder. During assembly, the top of the cylindrical light source holder is inserted into the lamp holder, and the upper snap ring is snapped into the upper snap ring groove for positioning. The bottom of the cylindrical light source holder is inserted into the bulb lampshade, and the lower snap ring is snapped into the lower snap ring groove for positioning. Through the above structure, the convenience and simplicity of assembly can be improved. At the same time, since the cylindrical light source holder and the circular plate form a sealed space with the bulb lampshade, the dustproof, waterproof and anti-mosquito performance can be effectively improved, which is beneficial to improving the effectiveness and stability of the illumination of the light source board.

[0025] During the actual application process, the outer diameter of the cylindrical light source holder matches the inner diameters of the lamp holder and the bulb lampshade. The cross-sectional shapes of the upper snap ring and the lower snap ring are the same as the cross-sectional shape of the snap ring groove. The upper snap ring and the upper snap ring are closely fitted and snapped into the snap ring groove. Through the above structure, the sealing performance of the snap connection can be ensured, the three-proof performance can be ensured, and the illumination effectiveness and stability can be ensured.

[0026] During the actual application process, a wire passing hole 8 is provided at the center of the circular plate. A driving circuit board is fixed inside the cylindrical light source holder, and the connection wire between the driving circuit board and the light source board is arranged in the wire passing hole. The connection of the power cord can be realized.

[0027] The utility model has positive effects: The structure of the utility model is reasonably arranged. The lamp holder, the bulb lampshade and the cylindrical light source holder are snap-positioned through the upper snap ring, the lower snap ring and the snap ring groove, and there is no need for gluing operation, which improves the convenience and simplicity of disassembly and installation, and can also ensure the stability of the snap connection. Moreover, since there is a circular plate at the bottom surface of the cylindrical light source holder and the light source board is fixed on the circular plate, a separate lighting space is formed between the circular plate and the bulb lampshade, which is also beneficial to improving the overall waterproof, dustproof and anti-mosquito performance, and has strong applicability and good practicability.

[0028] The standard parts used in this embodiment can be directly purchased from the market, and the non-standard structural components described in the specification can also be directly processed without doubt according to the existing common technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology, so no specific description will be made here.

[0029] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or modifications derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
