Embodiment 1
[0039] Example 1, such as image 3 As shown, a full-spectrum light source includes a light source module (10) and a control module (20). As an example, each light-emitting unit (100) is an LED light source, and it is easy to select a light source combination capable of realizing a full-spectrum solution at a target color temperature, so that the light source module (10) emits light that meets requirements.
[0040] In this embodiment, 4000 K, 5000 K, and 6000 K are used as target color temperatures, and the achievable color temperature range is 4000 K-6000 K. Within the above color temperature range, there are multiple satisfying color coordinate points for each target color temperature, that is, the effective color temperature area, such as figure 2 As shown, any color coordinate point in each effective color temperature area can be selected as the target color coordinate point. Preferably, the points on the blackbody radiation curve and the color coordinate points corresp...
Embodiment 2
[0059] Example 2, such as image 3 As shown, a full-spectrum LED light source, a light source module (10) and a control module (20), the structure of which is basically similar to that of Embodiment 1. The composition of the control module (20) is completely consistent with that of Embodiment 1.
[0060] Consistent with Example 1, in this example, with 4000 K, 5000 K, and 6000 K as the target color temperature, the achievable color temperature range is 4000 K-6000 K, and the maximum color temperature CCT max It is 6000 K, corresponding to the point (0.3221, 0.3318) on the color coordinates, and the minimum color temperature CCT min It is 4000 K, corresponding to the point (0.3796, 0.3797) on the color coordinates.
[0061] The difference from Embodiment 1 is that the composition of the light emitting unit (100) of the light source module (10) is different from Embodiment 1. In this embodiment, the four types of light-emitting units specifically include light-emitting unit 1...
Embodiment 3
[0068] Example 3, such as Image 6 As shown, a full-spectrum LED light source is composed of a light source module (10) and a control module (20), and its structure is basically similar to that of Embodiment 1.
[0069] Consistent with Example 1, in this example, with 4000 K, 5000 K, and 6000 K as the target color temperature, the achievable color temperature range is 4000 K-6000 K, and the maximum color temperature CCT max It is 6000 K, corresponding to the point (0.3221, 0.3318) on the color coordinates, and the minimum color temperature CCT min It is 4000 K, corresponding to the point (0.3796, 0.3797) on the color coordinates.
[0070] The difference from Embodiment 1 is that the light source module includes five light emitting units (100), specifically a combination of three PCLED light sources (101) and two monochromatic LED light sources (102). The five light-emitting units specifically include light-emitting unit 1, light-emitting unit 2, light-emitting unit 3, light-...
