Embodiment 1

[0040] refer to Figure 1 to Figure 6 , Embodiment 1 of the present invention discloses a lighting device, which includes a base 3 , a first lamp bead 1 , a second lamp bead 2 and a diffusion cover 4 . base 3 along the first direction (eg figure 1 The direction shown by the arrow x) extends, and the base 3 is provided with a plurality of circles around the first direction (such as figure 1The direction indicated by the middle arrow y) is set and faces different installation surfaces 31 . The first lamp bead 1 is arranged on the installation surface 31 along the first direction, the color temperature of the second lamp bead 2 is different from that of the first lamp bead 1 , and the second lamp bead 2 is arranged at intervals from the first lamp bead 1 . On each mounting surface 31, the vertical distance from the end face of the first lamp bead 1 away from the mounting surface 31 to the center of the base 3 (such as Figure 4 shown in r1) is equal to the vertical distance fr...

Embodiment 2

[0089] see Figure 11 , Embodiment 2 of the present invention discloses a lighting device, the difference between Embodiment 2 and Embodiment 1 is:

[0090] The lighting device further includes a third lamp bead 9 , which is an RGB lamp bead, and the third lamp bead 9 is arranged between the first lamp bead 1 and / or the second lamp bead 2 on the same mounting surface 31 . It can be understood that the third lamp bead 9 may be a lamp bead in which three colors of R, G, and B are packaged together. Of course, optionally, three independent R chips, G chips, and B chips are also densely arranged together. A relatively complete third lamp bead 9 is relatively formed. Warm white light, cool white light and RGB lamp beads are used to combine multi-color light, which makes the light quality of the lighting device higher.

[0091] Specifically, when the first lamp beads 1 and the second lamp beads 2 are respectively located on different installation surfaces 31, the first lamp beads ...

Embodiment 3

[0094] see Figure 12 , the third embodiment of the present invention discloses a lighting device, the difference between the third embodiment and the first embodiment is:

[0095] The lighting device also includes a third lamp bead 9, the third lamp bead 9 is an RGB lamp bead, the third lamp bead 9 is located on a mounting surface 31 different from the first lamp bead 1 and the second lamp bead 2, the third lamp bead 9 is disposed on the installation surface 31 along the first direction. It can be understood that the third lamp bead 9 may be a lamp bead in which three colors of R, G, and B are packaged together. Of course, optionally, three independent R chips, G chips, and B chips are also densely arranged together. A relatively complete third lamp bead 9 is relatively formed. Warm white light, cool white light and RGB lamp beads are used to combine multi-color light, which makes the light quality of the lighting device higher.

[0096] Specifically, when the first lamp bea...

Abstract

The invention relates to the field of lighting technology, and specifically discloses a lighting device, which includes a base, a first lamp bead, a second lamp bead with a color temperature different from that of the first lamp bead, and a diffusion cover. The base extends along the first direction, and the base is provided with a plurality of installation surfaces arranged around the first direction and facing differently. The first lamp bead is arranged on the installation surface along the first direction, and the second lamp bead is arranged at intervals from the first lamp bead. On each mounting surface, the vertical distance from the end surface of the first lamp bead facing away from the mounting surface to the center of the base is equal to the vertical distance from the end surface of the second lamp bead facing away from the mounting surface to the center of the base. End faces of the first lamp bead and the second lamp bead have intersection lines. The diffuser cover is arranged around the cover in the light emitting direction of the first lamp bead and the second lamp bead, and the distance from the center to the center is not less than the distance from the intersection line to the center. Such setting can increase the light output brightness and light output range of the lighting device and make the lighting device have a better light mixing effect.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a lighting device. Background technique [0002] In the process of film and television, advertising, and video content creation, a large number of lights are often required for supplementary light, such as spotlights, panel lights, etc., but the above-mentioned lights are relatively single-sided light, for example, when shooting mobile, due to the position of the camera When moving, the angle between the subject and the subject changes, which will cause light discontinuity, and the workload of retouching pictures and videos in the later stage is very heavy. For example, light bulbs can achieve relatively omnidirectional light output, but the power of the bulb is often not large enough, and its light output surface is small, which is difficult to meet the needs of changing scenes. Of course, some plant growth lights or warning lights can also achieve similar multi-faceted light o...
