[0026] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.
[0027] like Figures 1 to 6 As shown, according to an embodiment of the present invention, a strip-shaped combined light source for detecting eyeglass lenses includes a base 100 and light-emitting components 200. The base 100 includes a main body 110 and a seat 120. Multiple seat 120s are provided, all of which are disposed around the periphery of the main body 110. The multiple seat 120s are arranged in a ring around the vertical central axis of the main body 110 and are arranged at intervals. The length direction of the seat 120 is perpendicular to the axial direction of the vertical central axis. The seat 120 is provided with a receiving groove 121. The length direction of the receiving groove 121 is in the same direction as the length direction of the seat 120, and one side of the receiving groove 121 extends into the main body 110. The lower part of the receiving groove 121 extends to the bottom end face of the base 100 and forms a first opening 122. Multiple light-emitting components 200 are provided and are respectively disposed in the multiple receiving grooves 121.
[0028] In this embodiment of the invention, the lens to be tested can be placed below the strip-shaped combined light source for testing eyeglass lenses. The light-emitting component 200 is disposed in the receiving groove 121, and the light emitted by the light-emitting component 200 can illuminate the lens to be tested. Multiple seats 120 are arranged in a ring around the vertical central axis of the main body 110 and are spaced apart in sequence, so that the strip-shaped combined light source for testing eyeglass lenses can be illuminated by the multiple light-emitting components 200 arranged in a ring. This provides high adaptability to circular lenses to be tested and can ensure the illumination effect. Furthermore, since one side of the receiving groove 121 extends into the main body 110, the light-emitting component 200 in the receiving groove 121 can illuminate the part of the lens to be tested located below the main body 110, which can further improve the uniformity and adaptability of the illumination and further ensure the lighting effect.

[0030] By controlling multiple light-emitting components 200 with the first and second controllers respectively, the difficulty of independent control can be reduced, the wiring difficulty can be reduced, the timing synchronization accuracy can be improved, the image acquisition delay can be reduced, and the lighting effect can be guaranteed.
[0031] Specifically, the color temperature of the light emitted by the light-emitting component 200 in the receiving groove 121 of the first seat 124 is different from that of the light emitted by the light-emitting component 200 in the receiving groove 121 of the second seat 125. One of the light colors is 430nm blue light and the other is 620nm red light. The first and second controllers control the multiple light-emitting components 200 respectively, so that the strip combination light source used for detecting eyeglass lenses emits light of a single color temperature or red and blue mixed light.
[0032] Reference Figure 4 and Figure 5 In some embodiments of this utility model, multiple seats 120 are arranged symmetrically in pairs to further ensure the uniformity of light emission.
