Description

Technical Field

[0001] The utility model relates to the field of ceiling lamps, in particular to an RGB direct-down ceiling lamp with uniform color mixing. Background Art

[0002] RGB ceiling lights are surface-mounted lamps that are commonly used in homes, staircases, and corridors. They have the advantages of easy installation, beautiful appearance, high light efficiency, uniform illumination, and a wide, non-glare irradiation area. Due to the accelerated development of smart lighting in recent years, user groups have more diversified demands for products, prompting this product to continue to generate more new demands on the original form and function. For example, in order to increase the sense of atmosphere in home use, colored ambient lighting is added to the original basis.

[0003] During use, existing RGB ceiling lights often have uneven color mixing due to the distribution and angle of the RGB lamp beads, which can easily lead to uneven red, green and blue color mixing and rainbow stripes on the edges, affecting the user's experience.

[0004] Therefore, in order to address the above-mentioned problem that the red, green and blue colors are easily mixed unevenly and rainbow stripes appear on the edges, which affects the user's sense of use, an RGB direct-down ceiling lamp with uniform color mixing can be designed. By calculating and adjusting the position and angle of each RGB lamp bead, the problem of uneven red, green and blue colors and rainbow stripes appearing on the edges can be solved. Utility Model Content

[0005] In order to overcome the problem of existing color-mixing ceiling lamps, during use, the distribution and angle of the RGB lamp beads usually affect the uniformity of color mixing, which can easily lead to uneven red, green and blue color mixing, and rainbow stripes on the edges, affecting the user's sense of use.

[0006] The technical solution of the utility model is: an RGB direct-down ceiling lamp with uniform color mixing, comprising a ceiling bottom shell, an aluminum base plate, an LED module and a diffusion cover; an LED mounting position is provided inside the ceiling bottom shell, an aluminum base plate for fixing the LED module is provided inside the LED mounting position, an LED module for serving as a light source is provided on the surface of the aluminum base plate, the LED module comprises multiple groups of RGB lamp beads, the multiple groups of RGB lamp beads diffuse outward from the center of the surface of the aluminum base plate, and any three adjacent groups of RGB lamp beads are arranged in an isosceles triangle, and a diffusion cover for reducing light loss is provided below the ceiling bottom shell.

[0007] Preferably, compared with the current hybrid ceiling lights on the market, which are prone to problems such as uneven mixing of colored red, green, and blue and rainbow stripes appearing at the edges, affecting the user's sense of use, in this application, multiple groups of RGB lamp beads of the LED module are combined. Taking the center point of the aluminum substrate as the reference, the adjacent two RGB lamp beads in the first circle have a linear distance of 30 mm and an angle of 60 degrees, and so on, evenly arranged on the entire aluminum substrate. Any adjacent 3 RGB lamp beads are arranged in an equilateral triangle. Since the encapsulation chips of the RGB lamp beads are arranged in a "Sichuan" character, the colors on both sides can be ensured that the different color lights of the adjacent RGB lamp bead are not interfered after being magnified by the lens on the surface of the RGB lamp bead.

[0008] As a preference, four groups of mounting holders are provided around the inner wall of the LED mounting position, and first-level mounting slots are opened inside the four groups of mounting holders. Two groups of second-level mounting slots are symmetrically opened at the lower edge of the ceiling bottom shell.

[0009] As a preference, a power supply mounting position is opened at the top of the ceiling bottom shell, and a wire outlet hole is opened at the center of the top of the ceiling bottom shell, and the wire outlet hole penetrates through the ceiling bottom shell.

[0010] As a preference, a power supply group is provided at the center of the upper end of the aluminum substrate, and the power supply group is electrically connected to the LED module, and the power supply group is located inside the power supply mounting position.

[0011] As a preference, four groups of substrate mounting buckles are provided around the outer end of the aluminum substrate, connection blocks are provided between the four groups of substrate mounting buckles and the aluminum substrate, and the four groups of substrate mounting buckles are fixedly connected to the aluminum substrate through the connection blocks.

[0012] As a preference, the four groups of substrate mounting buckles are snap-fitted with the four groups of first-level mounting slots, and anti-disengagement buckles are provided at one end of each of the four groups of substrate mounting buckles away from the aluminum substrate.

[0013] As a preference, two groups of cover body mounting buckles are symmetrically provided at the upper edge of the diffusion cover, and the cover body mounting buckles are snap-fitted with the second-level mounting slots.

[0014] The beneficial effects of the present utility model:

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See also Figure 1-Figure 5 The utility model provides an embodiment: an RGB direct-down ceiling lamp with uniform color mixing, comprising a ceiling bottom shell 1, an aluminum base plate 2, an LED module 3 and a diffusion cover 4; an LED mounting position 5 is provided inside the ceiling bottom shell 1, an aluminum base plate 2 for fixing the LED module 3 is provided inside the LED mounting position 5, an LED module 3 for serving as a light source is provided on the surface of the aluminum base plate 2, the LED module 3 comprises multiple groups of RGB lamp beads 15, the multiple groups of RGB lamp beads 15 diffuse outward from the center of the surface of the aluminum base plate 2, and any three adjacent groups of RGB lamp beads 15 are arranged in an isosceles triangle, and a diffusion cover 4 for reducing light loss is provided below the ceiling bottom shell 1.

[0024] See also Figure 1-Figure 2In this embodiment, four groups of mounting sockets 9 are provided around the inner wall of the LED mounting position 5, and a first-level mounting slot 8 is provided inside the four groups of mounting sockets 9. Two groups of second-level mounting slots 10 are symmetrically provided at the lower edge of the ceiling bottom shell 1. A power mounting position 6 is provided on the top of the ceiling bottom shell 1, and a wire outlet hole 7 is provided at the top center of the ceiling bottom shell 1. The wire outlet hole 7 passes through the ceiling bottom shell 1, and is combined with the first-level mounting slot 8 and the second-level mounting slot 10. When installing the ceiling lamp, the staff can assemble the diffusion cover 4 and the aluminum base plate 2 together through the first-level mounting slot 8, the second-level mounting slot 10 and the ceiling bottom shell 1, and combine the power mounting position 6 with the wire outlet hole 7 so that the power supply group 14 can be positioned through the power mounting position 6. At the same time, the power supply group 14 can be connected to an external power supply through the wire outlet hole 7 to power the ceiling lamp.

[0025] See also Figure 2-Figure 3 In this embodiment, a power supply group 14 is provided at the center of the upper end of the aluminum substrate 2. The power supply group 14 is electrically connected to the LED module 3. The power supply group 14 is located inside the power supply mounting position 6. Four groups of substrate mounting clips 12 are provided around the outer end of the aluminum substrate 2. A connecting block 11 is provided between the four groups of substrate mounting clips 12 and the aluminum substrate 2. The four groups of substrate mounting clips 12 are fixedly connected to the aluminum substrate 2 through the connecting block 11. After the four groups of substrate mounting clips 12 are combined so that the four groups of substrate mounting clips 12 are connected to the aluminum substrate 2 through the connecting block 11, the staff can insert the aluminum substrate 2 into the first-level mounting slot 8 through the substrate mounting clips 12 during installation, thereby fixing the aluminum substrate 2 in the LED mounting position 5.

[0026] See also Figure 2-Figure 5 In this embodiment, four groups of substrate mounting buckles 12 are matched and engaged with four groups of primary mounting slots 8. The four groups of substrate mounting buckles 12 are all provided with anti-drop buckles 13 at the end away from the aluminum substrate 2. Two groups of cover body mounting buckles 16 are symmetrically provided at the upper edge of the diffusion cover 4. The cover body mounting buckles 16 are matched and engaged with the secondary mounting slots 10. After the substrate mounting buckles 12 are engaged with the primary mounting slots 8 through the anti-drop buckles 13, the anti-drop buckles 13 can prevent the substrate mounting buckles 12 from detaching from the primary mounting slots 8. At the same time, when installing, the staff can clip the diffusion cover 4 into the secondary mounting slots 10 through the cover body mounting buckles 16, thereby fixing the diffusion cover 4 under the ceiling bottom shell 1, so that the diffusion cover 4 distributes the light more evenly in the entire lighting area, reduces glare and glare, and improves lighting comfort.

[0027] During work, the staff can clip the aluminum substrate 2 into the primary mounting slot 8 through the substrate mounting buckle 12, thereby fixing the aluminum substrate 2 in the LED mounting position 5. After the substrate mounting buckle 12 is engaged with the primary mounting slot 8 through the anti-drop buckle 13, the anti-drop buckle 13 can prevent the substrate mounting buckle 12 from detaching from the primary mounting slot 8.

[0028] At the same time, during installation, the staff can clip the diffusion cover 4 into the secondary installation slot 10 through the cover body installation buckle 16, thereby fixing the diffusion cover 4 on the ceiling bottom shell 1, so that the diffusion cover 4 can distribute the light more evenly in the entire lighting area, reducing glare and dazzling.

[0029] By combining the power installation position 6 with the wire outlet hole 7 , the power supply group 14 can be positioned through the power installation position 6 , and the power supply group 14 can be connected to an external power source through the wire outlet hole 7 to power the ceiling lamp.

[0030] Through the above steps, the present application combines multiple groups of RGB lamp beads 15 of the LED module 3, so that they are based on the center point of the aluminum substrate 2. The two adjacent RGB lamp beads 15 in the first circle are evenly arranged on the entire aluminum substrate 2 with a straight line spacing of 30 mm and an angle of 60 degrees. And so on. Any three adjacent RGB lamp beads 15 are arranged in an equilateral triangle. Since the package chips of the RGB lamp beads 15 are arranged in a "Chuan" shape, the colors on both sides are magnified by the lens on the surface of the RGB lamp beads 15, which can ensure that the different colors of light of another adjacent RGB lamp bead 15 are not interfered with.
