Description

Technical Field

[0001] This utility model relates to the field of outdoor spotlight technology, and in particular to an adjustable color temperature outdoor spotlight. Background Technology

[0002] Outdoor spotlights are lighting fixtures used primarily for auxiliary lighting outdoors. They are commonly used to illuminate outdoor decorations (such as stone carvings, road signs, etc.), outdoor roads, and outdoor buildings, allowing people to appreciate the different aesthetics of objects at night.

[0003] Most existing outdoor spotlights only have basic lighting functions, but by illuminating different or the same objects with different color temperatures and brightness in different application scenarios, the lighting effect can be improved, the visual brightness can be adjusted, and people can have a better visual experience.

[0004] However, to achieve the above effect, existing outdoor spotlights require the purchase of various specifications of outdoor spotlights. By using different color temperatures and brightness of different specifications of outdoor spotlights to achieve the above effect, the purchase and use costs are higher than using outdoor spotlights of the same specification. In addition, if there are unpredictable errors in forecasting, the wrong specifications of outdoor spotlights may be purchased, resulting in the loss of the required illumination effect, causing repeated purchases and extending the construction period.

[0005] Furthermore, if the color temperature and brightness of the spotlights need to be readjusted due to unforeseen circumstances such as weather or season, the outdoor spotlights will need to be disassembled and reassembled, resulting in extremely high installation and maintenance costs. Therefore, improvements are necessary. Utility Model Content
