[0026] Embodiment:

[0027] A light shielding and light adjusting integrated support, as shown in Figure 1 The light shielding part 1 is used to constrain the amount of light passing through the light shielding part 1, the light adjusting part 2 and the supporting part 3 cooperate to play a supporting role and a connecting function with external accessories, and further includes a structure that can be adjusted to realize the adjustability of light.

[0028] The support is integrally formed, specifically, the support is made of plastic material, and the support is integrally formed by injection molding process.

[0029] The light shielding part 1 is a light shielding plate 4, the top surface of the light shielding plate 4 is provided with light transmission holes 5 communicating with the bottom surface, and the number of the light transmission holes 5 is not fixed. In some embodiments, the number of the light transmission holes 5 is three. Each light transmission hole 5 is symmetrically arranged about the central axis of the light shielding plate 4. The light is more uniform in the length direction. The light transmission holes 5 on both sides are rectangular. The light transmission hole 5 in the middle is elliptical or circular. In some embodiments, the light transmission holes 5 on both sides and in the middle are all rectangular, and the corner points of each are rounded. The light transmission holes 5 allow the light partially incident on the light shielding plate 4 to pass through the light shielding plate 4.

[0030] Referring to Figure 2 As shown, the light adjusting part 2 includes a containing tube 6 connected at both ends of the light shielding part 1 in the length direction, and the containing tube 6 is fixedly connected with a ball head screw 12. One end of the ball head screw 12 is a ball head, and the other end is a nail part, wherein the nail part is inserted into the containing tube 6 and fixedly connected with the containing tube 6 by self-tapping or interference fit. The ball head is rotationally connected with the support structure.

[0031] The axial direction of the containing tube 6 is perpendicular to the top surface of the light shielding plate 4. The containing tube 6 is arranged on a containing plate 7, and the containing plate 7 is arranged at the end of the light shielding plate 4 and arranged perpendicularly to the light shielding plate 4.

[0032] The outer side wall of the containing tube 6 is fixedly connected with a plurality of reinforcing rib plates 8. The strength of the containing tube 6 is improved by the reinforcing rib plates 8. The reinforcing rib plates 8 are connected between the containing tube 6 and the reinforcing rib plates 8.

[0033] Referring to Figure 2 , 3 As shown, the two containing plates 7 are connected and form the support part 3. The support part 3 is provided with a plurality of weight reduction holes 9 and or weight reduction hollows 10. The difference between the weight reduction holes 9 and the weight reduction hollows 10 is that the weight reduction holes 9 are non-through holes, while the weight reduction hollows 10 pass through the support structure. As can be seen from the above scheme, the weight of the support part 3 is relatively strong, which is beneficial to the lightweight of the lighting device and saves materials.

[0034] The support part 3 has a through hole and forms an adjusting seat 11 through the through hole. The adjusting seat 11 is adjustably connected with the ball head screw 12. Specifically, the ball head screw 12 and the adjusting seat 11 are threadedly connected. The thread connection of the ball head screw 12 and the adjusting seat 11 allows the rotation of the ball head screw 12 to adjust the depth of the ball head screw 12 screwed into the adjusting seat 11, thereby realizing the adjustable connection of the ball head screw 12 and the adjusting seat 11.

[0035] The adjusting seat 11 is arranged at the middle of the support part 3 in the length direction.

[0036] The two ball screws 12 and the adjusting screw 13 are not on the same line. In use, the two ball screws 12 and the adjusting screw 13 are connected with the outer cover body, the distance between the through hole and the outer cover body is changed by rotating the adjusting screw 13, and thus the angle between the support and the outer cover body is adjusted.

[0037] The number of components is reduced and the manufacturing cost and assembly difficulty are reduced by the integrally formed light shielding part 1, light adjusting part 2 and supporting part 3. The stability of the light shielding effect and the adjusting precision is improved by the integrally designed light shielding part 1 and light adjusting part 2. The whole adjusting process is more convenient and accurate, and the stability and consistency are better by the integrally formed light shielding part 1, light adjusting part 2 and supporting part 3 and the adjustable connection of the through hole and the ball screw 12. The support is not only suitable for lighting equipment, but also suitable for other optical adjusting equipment, and has wide application prospect.

[0038] The above-mentioned embodiments are only the preferred schemes of the present application, and do not limit the present application in any form. Other variants and modifications can be made without exceeding the technical schemes recited in the claims.
