Abstract

The invention relates to a color-controllable LED luminescent lamp. LED light sources are composed of mini-LED chips with the relatively small sizes, so that the number of the LED light sources capable of being contained in a lampshade is increased, the whole LED luminescent lamp can show more color types, and free showing and switching of multiple colors can be achieved.

Description

technical field [0001] The present application relates to the technical field of light-emitting devices, in particular to a color-controllable LED light-emitting lamp. Background technique [0002] LED filament is a common light-emitting device, which has a wide range of uses and low cost, and can meet the lighting needs in most cases. However, LED filaments capable of emitting light in many different colors are a hot area of ​​research as the needs of residents are increasing. [0003] Traditional LED filaments are generally composed of blue light chips, ceramic substrates and phosphors. Both ends of a ceramic substrate are fixedly provided with metal pins, which are used as a connection medium between the LED filament and other components. On the surface of the ceramic substrate, a plurality of blue light chips are arranged at intervals, and the plurality of blue light chips and the ceramic substrate form a light-emitting component. Finally, the surface of the light-emi...
