In this embodiment, the concentrator 33 includes two first reflectors 333 and two second reflectors 334 that are arranged opposite to each other, constituting the upper opening 332 and the lower opening 331. The surfaces of the first reflectors 333 and the second reflectors 334 are provided with reflective films or reflective sheets, forming the reflective surface 335. The reflective surface 335 is an arc-shaped surface with a gradually changing inclination curvature. The arc-shaped surface extends obliquely from bottom to top, that is, the reflectors gradually move away from the central axis of the concentrator 33 from bottom to top.

[0039] like Figure 5As shown, the length of the projection screen 34 is defined as L, the distance between the projection screen 34 and the lamp body is defined as D, and the included angle α between the two first reflectors 333 is greater than or equal to the included angle β between the two first reflectors 333. In the existing structure, the closer the second lamp body 32 is to the projection screen 34, the higher the light utilization rate and the worse the illumination uniformity X. However, after adding the condenser 33 between the first lamp body 21 and the projection screen 34, the following data was obtained through multiple research and development experiments: as the second lamp body 32 gets closer to the projection screen 34, the illumination uniformity gradually becomes more uniform. In addition, because the larger the included angle α is, the higher the lamp body lumen value and the higher the light utilization rate, but the more heat the second lamp body 32 generates, it is easy to cause the temperature to exceed the temperature that the projection screen 34 can withstand, causing the projection screen 34 to turn blue or its non-projection area to have higher light transmittance, thus affecting the projection effect. Therefore, it is necessary to determine the range of values ​​for the included angle α through multiple research and development experiments. According to the test data, an illumination uniformity X less than 3 is considered uniform, and the closer it is to 1, the more uniform it is. When α = 20°, the light utilization rate is 25%–35%, the illumination uniformity X = 1.05–1.35, and D = 2L–3L; when α = 30°, the light utilization rate is 35%–44%, the illumination uniformity X = 3.5–4.5, and D = 1.2L–2L; when α = 40°, the light utilization rate is 45%–53%, the illumination uniformity X = 3.2–4.3, and D = 1L–1.5L; when α = 50°, the light utilization rate is 54%–60%, the illumination uniformity X = 2.6–4, and D = 0.8L–1L; when α = 60°, the light utilization rate is 61%–71%, the illumination uniformity X = 1.5–3, and D = 0.6L–0.8L; when α = 70°, the light utilization rate is… The light utilization rate is 66%–73%, the light uniformity X = 1.4–2.8, and D = 0.5L–0.65L; when α = 80°, the light utilization rate is 70%–77%, the light uniformity X = 1.2–1.6, and D = 0.43L–0.5L; when α = 90°, the light utilization rate is 80%–88%, the light uniformity X = 1.04–1.3, and D = 0.35L–0.43L; when α = 100°, the light utilization rate is 83%–94%, the light uniformity X = 1.1–1.5, and D = 0.29L–0.35L; when α = 110°, the light utilization rate is 88%–96%, the light uniformity X = 2–3, and D = 0.23L–0.3L. When the included angle α between the two first reflectors 333 is between 30° and 100°, the light utilization rate is 35% to 94%, X = 1.04 to 4.5, and D = 0.27L to 2L. When the included angle α between the two oppositely arranged first reflectors is between 40° and 90°, the relationship between L and D satisfies D = 0.35L to 1.5L, the light flux utilization rate of the focusing element is 45% to 88%, and the illumination uniformity X = 1.04 to 4.3.When the included angle α between the two first reflectors 333 is between 40° and 100°, the relationship between L and D satisfies D = 0.27L to 1.5L, the luminous flux utilization rate of the focusing element is 40% to 94%, and the illumination uniformity X = 1.1 to 4.3. When the included angle α between the two first reflectors 333 is between 50° and 90°, the relationship between L and D satisfies D = 0.35L to 1L, the luminous flux utilization rate of the focusing element is 54% to 88%, and the illumination uniformity X = 1.04 to 4. The projection light effect of the first projection component 2 constitutes the atmospheric effect of the second projection component 3. The second projection component 3 at least forms lyrics, fonts, or pattern projections. The projection screen 34 is a black and white screen that projects lyrics onto a wall, floor, film, or tabletop. When the projection screen 34 receives the lyrics information transmitted from the motherboard, it illuminates the corresponding liquid crystal to form the lyrics projection. As the lyrics projection of the second projection component 3 changes, the first projection component 2 automatically or manually projects red, blue, green, or any combination of these three colors, or a rhythmic light effect, or a changing projection pattern. A speaker mounted on the base 1 receives audio files transmitted from the motherboard and plays sound. When a song is at a high pitch, the rotation speed of the first projection component 2 gradually increases or displays a rhythmic light effect; when a song progresses to a low pitch, the rotation speed of the first projection component gradually decreases or remains constant. The lyrics projected by the second projection component 3 fall onto a wall, screen, or floor. The projection light effect of the first projection component 2 surrounds the lyrics or allows the lyrics to be observed through the light effect formed by the first projection component 2. When the ambient light 100 is connected to a microphone, karaoke can be performed. The first projection component 2 includes a central strong light effect and a weak light effect surrounding the strong light effect. The lyrics, fonts, or pattern projection can be observed through the central optics and / or outer edge optics of the first projection component 2. When the first projection component 2 projects upwards and the second projection component 3 projects horizontally, the light effect projected by the second projection component 3 can be seen through the weak light effect formed by the first projection component 2; or when the first projection component 2 projects horizontally, the strong light effect or weak light effect of the second projection component 3 is set around the light effect of the second projection component 3.

[0040] like Figure 9 As shown, another embodiment of the present invention is illustrated.

The light-emitting area of ​​the second lamp body 32 is greater than or equal to the projection area of ​​the projection screen 34. The light emitted around the second lamp body 32 is enhanced by the reflective surface 335, thereby improving the light utilization rate and illumination uniformity, and meeting the requirements of low power, high brightness, and low heat.

[0046] (5) The condenser 33 includes two first reflectors 333 and two second reflectors 334 arranged around the second lamp body 32. The length of the projection screen 34 is defined as L, and the distance between the projection screen 34 and the second lamp body 32 is defined as D.
