AI Technical Summary
The ducts of existing downlights without blue light lack an effective positioning structure, which makes them prone to displacement during vibration or movement, affecting the negative ion output path and reducing the air purification effect.
The system employs a clamping positioning plate and bolt fixing structure. By tightening the bolts onto the threaded holes, the conduit and output wire are fixed within the wire-passing holes. The combination of the plastically deformable tube structure and the clamping positioning plate ensures the stability of the conduit position.
It effectively prevents the duct from shifting under vibration or external force, ensuring that negative ions are smoothly ejected, improving air purification effect, and enhancing user satisfaction and product performance.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of no blue light down lamp, especially in no blue light with negative oxygen ion down lamp. BACKGROUND
[0002] With the continuous improvement of people's pursuit of healthy life quality, no blue light lamps have become a popular trend in the current lighting field. The light emitted by no blue light lamps can effectively reduce the damage to the human eye, greatly meeting people's needs in protecting vision. Among many no blue light lamp products, down lamp, as a common lighting device, its function is also constantly expanding and improving.
[0003] The existing no blue light down lamp structure is usually connected with a negative ion generator, which uses the negative ions generated by the negative ion generator to improve the air environment. The negative ion generator outputs negative ions outward through a conduit and a carbon fiber brush to achieve air purification, dust removal and sterilization, etc., creating a healthier and more comfortable living space for users. However, in the prior art, the conduit for connecting the negative ion generator and the wire for connecting with the lamp panel both lack effective positioning structures. When the wire and the conduit are inserted into the lamp, the wire can be positioned by connecting with the circuit board, while the conduit is only positioned by its own gravity. This positioning method has obvious defects. During the daily use of the lamp, the position of the conduit is easily shifted due to factors such as vibration and movement. Once the position of the conduit changes, it will interfere with the output path of the negative ions, thereby seriously affecting the effect of the negative ion output, and the negative ion generator cannot fully play its role in improving air quality.
[0004] For example, in actual use scenarios, when the lamp is installed on the ceiling, if the house is renovated and the vibration is generated, or the user cleans the environment around the lamp, etc., the conduit positioned by gravity alone may shift in position. According to relevant market feedback data, about [X]% of users feedback that the negative ion air purification effect is significantly weakened after using the no blue light down lamp with the existing structure for a period of time. After inspection, it is found that most of the problems are caused by the shift of the position of the conduit. This not only reduces the user's satisfaction with the product, but also limits the comprehensive performance of the no blue light down lamp in improving the quality of life. Therefore, it is necessary to improve the existing no blue light down lamp structure. UTILITY MODEL CONTENTS
