Technical Field
[0001] The utility model relates to the technical field of LED lighting, in particular to an LED monochromatic soft filament lamp. Background Technique
[0002] In recent years, the flexible filament technology has been significantly developed, especially in the field of LED lighting. The flexible filament uses a soft and plastic-shaped copper-clad FPC film as the base material, with the characteristics of being slender, soft and plastic, 360-degree light emission, energy saving and environmental protection, and is very close to the light distribution effect of traditional tungsten filament lamps. The characteristics of the flexible filament make them have obvious advantages in commercial atmosphere lighting and personalized lighting design. Compared with rigid filament lamps, the flexible filament lamps have richer and more beautiful shapes and are suitable for a variety of lighting scenarios. The preparation process and structural design of the flexible filament are also constantly improving to meet different application requirements and market trends. In addition, the application of the flexible filament is not limited to traditional spherical bulbs, but can also be made into various letters and creative lamps, which provides a broad creative space for designers. The market prospect of the flexible filament lamp is promising and is expected to occupy an important position in the future lighting market.
[0003] Flexible LED strip lights are widely used in various lighting systems because of their softness, plasticity, 360-degree light emission, energy saving and environmental protection. However, the power supplies in different lighting systems are different. Generally, the common voltages of indoor power supplies are DC5V, DC12V, DC24V, DC36V, and the voltage of outdoor power supplies is AC220V. While the flexible LED strip lights are generally powered by a DC3V voltage, which makes it necessary to customize or add an additional buck power supply module to adapt the strip lights when they are applied in various lighting systems, thus increasing the material cost and construction difficulty. Therefore, we have designed an LED monochromatic soft filament lamp. Content of the Utility Model
