Chip lamp bead and luminaire

A chip lamp bead, comprising:

• a packaging body and a lamp bead body packaged in the packaging body,
• wherein the lamp bead body comprises a substrate, and a first luminous body, a second luminous body and a control chip provided on the substrate;
• the first luminous body and the second luminous body are respectively connected to corresponding control terminals of the control chip, wherein the first luminous body is a luminous body of a preset color system, and the second luminous body is a luminous body of a white light color system;
• the control chip is configured to control, in response to a control signal, control the first luminous body and/or the second luminous body to light up based on the control signal;
• wherein the substrate comprises a first substrate and a second substrate, wherein the control chip is mounted on the first substrate through a preset die-bonding process, and the first luminous body and the second luminous body are mounted on the second substrate through the preset die-bonding process;
• wherein the chip lamp bead further comprises a luminous-body fixing structure, wherein the substrate is mounted on one end surface of the luminous-body fixing structure;
• wherein another end surface of the luminous-body fixing structure is provided with a first connection structure corresponding to the control chip, and a second connection structure corresponding to the first luminous body and the second luminous body;
• and
• wherein the luminous-body fixing structure is a patch structure, and the first and second connection structures on the other end surface thereof include an input terminal, a negative electrode and a positive electrode, where the input terminal and the negative electrode are at positions corresponding to the first substrate, and the positive electrode is at a position corresponding to the second substrate, a green strip made from copper foil or other conductive materials is provided between the connection structures, and a green solder mask is coated on the green strip.
