The structure usually includes a transparent glass shell, a filament, a glass stem with a sealed wire, and a base. Although this type of lamp is relatively cheap and has a light distribution close to full angles, its lifespan and energy efficiency are not high.

[0068] In order to meet the demand for high-definition lighting effects, LED lamps with better effects are gradually emerging, especially SMD devices due to their characteristics and advantages in color reproduction, color consistency, viewing angle, overall picture effect and thin structure. However, the mainstream lighting LEDs on the market are blue light chips that excite phosphors to achieve white light or warm white light lighting. This mode has the hazard of blue light, and at ultra-low color temperatures of around 2000K, problems such as low light efficiency, large light decay, and insufficient color rendering will occur.
