Problems solved by technology

Colored light lighting can adjust different color temperatures to achieve a more aesthetic presentation of artworks. Existing colored light lighting often has the problem of reddish light. This is due to the red light shift caused by uneven light mixing. This is not good for lighting effects
In addition, for point light sources or surface light sources, far-field lighting will have shadows, which is caused by the small exit angle of light and insufficient uniformity

no. 1 example

[0029] see figure 1 and figure 2 , the art exhibition lighting device of the present invention includes an injection molded base 10 formed by an injection molding process. The injection molding base 10 can be a polymer material, such as epoxy resin, silicone resin, polyimide, etc., and the injection molding base 10 itself can be transparent or translucent.

[0030] The injection molding base 10 has a first reflective cavity 12 and a second reflective cavity 13 , and there is a stepped portion 16 between the first reflective cavity 12 and the second reflective cavity 13 . The first reflective cavity 12 , the second reflective cavity 13 and the stepped portion 16 can be formed together by an injection mold. Of course, the first reflective cavity 12 can also be formed first, and then the second reflective cavity 13 and the stepped portion 16 can be formed. Particularly, the sidewall inclination angle (relative to the horizontal plane) of the first reflective cavity 12 is small...

[0039] see Figure 5, the structure of this embodiment is basically the same as that of the first embodiment, and the difference is that the device includes five LEDs, namely the red LED21, the first green LED24, the first blue LED26 and the second green LED25 , the second blue LED27; when viewed from above, the first green LED24 and the second green LED25 are arranged on the long axis of the first ellipse of the first reflective cavity 12, and the first blue LED26 and the second blue LED The LEDs 27 are arranged on the minor axis of the first ellipse of the first reflective cavity 12 . At this time, due to the arrangement of multiple green LEDs and blue LEDs, it is not necessary to additionally set the angle with the long axis, and only need to alternately arrange multiple green LEDs and blue LEDs to achieve basic light mixing.

[0041] For details, please refer to Image 6 , the structure of this embodiment is basically the same as that of the first embodiment, the difference is that there are a plurality of third reflective cavities 18 on the stepped part 16 and third reflective parts 17 on the side walls of the third reflective cavities 18, green The light LED and the blue LED are fixed in the third reflective cavity 18 . In particular, when viewed from above, the opening size of the third reflection cavity 18 is smaller than the opening size of the first reflection cavity 12 . The position of the third reflective cavity 18 can be set according to the positions of the three LEDs in the first embodiment, or can be set according to the positions of the five LEDs in the second embodiment. Such a setting can make the three kinds of red, green and blue lights emit at a large angle, and at the same time realize the adjustment of color temperature and uniform light mixing.

Abstract

The invention provides an art exhibition lighting device. An oval first reflection cavity is used for reflecting light of the red light LEDs, divergence of the red light LEDs can be guaranteed, then the light of the red light LEDs is evenly mixed with light emitted by the green light LEDs and light emitted by the blue light LEDs, the problem of red light flooding is prevented, and the lighting color is fine and smooth. Moreover, the green-light LED and the blue-light LED are arranged on a step part and are higher than the red-light LED, so that the uniformity during light mixing can be further improved, preferably, the red-light LED independently uses an injection molding elliptical lens, and the divergence of the light emitting angle of the red-light LED is ensured.

Description

technical field [0001] The invention relates to the technical field of LED packaging, in particular to an art exhibition lighting device. Background technique [0002] In addition to the use value, works of art have their special value, that is, the ornamental value, which is reflected in the spirit and culture - so as to satisfy people's certain aesthetic and spiritual needs. When artworks are exhibited, exhibited or auctioned, it is often necessary to embellish and decorate artworks, and the most commonly used is to use decorative lamps for lighting and decoration. The beauty of handicraft decorative lights is very important. Lighting is an organic component of the entire handicraft exhibition. Its ultimate purpose is to enable the light to illuminate the handicraft evenly, so that people's visual function can play a good role. Colored light lighting can adjust different color temperatures to achieve a more aesthetic presentation of artworks. Existing colored light lighti...
