Illuminating device

An illuminating device, comprising:

• a first light source configured to generate a first light;
• a second light source configured to generate a second light;
• a first converging element provided in an optical path of the first light and an optical path of the second light;
• an adjusting mechanism;
• a light concentrating mechanism,
• wherein the light concentrating mechanism is provided on the adjusting mechanism, the adjusting mechanism is configured to adjust a position of the light concentrating mechanism, and the light concentrating mechanism is located in the optical path of the second light passing through the first converging element or located out of the optical path of the first light passing through the first converging element;
• a second converging element;
• a goes before optics (GOBO), wherein the first light is transmitted to the GOBO through the first converging element, or the second light is transmitted to the GOBO through the first converging element and the light concentrating mechanism, and
• a wavelength conversion element,
• wherein the first light source comprises a substrate and a light-emitting chip, the light-emitting chip is arranged on the substrate, the substrate is provided with a through hole, and the second light is transmitted to the GOBO via the through hole;
• and
• wherein the wavelength conversion element is arranged on the substrate via the through hole;
• and
• wherein the second converging element is arranged between the second light source and the first light source, and is configured to converge the second light emitted by the second light source to the wavelength conversion element in the through hole.
