Description

Reflective lighting system for showcase

One, the technical field

The invention relates to a lighting system for a showcase, in particular to a reflecting lighting system for the showcase.

Second, background Art

The showcase used in museums and art libraries is an important equipment for exhibition and display of cultural relics, the exhibition and display space is required to be completely isolated from the external environment, and illumination light is required to be arranged inside the showcase so that visitors can watch the cultural relic exhibits conveniently. The special cultural relic exhibit, such as highly sensitive material exhibits of parchment paper, straw paper, textile and the like, has higher requirement on the environment, the fluctuation of temperature and humidity directly influences the service life of the exhibit, and the heating of the lamp is just an important factor which directly influences the fluctuation of temperature and humidity in the exhibiting space. The existing solution in the industry is to introduce an LED lighting fixture or an optical fiber lighting fixture, wherein the LED lighting fixture dissipates heat when working, and adversely affects cultural relic exhibits while lighting. Fiber-optic drop-in lighting fixtures are expensive and inconvenient for routine maintenance.

Third, the invention

The invention provides a reflective lighting system for a showcase, which consists of a lighting source, an optical lens, a reflector and a lighting bracket. The illumination light source is positioned in the cabinet body, is lower than the reference surface of the display platform and is completely isolated from the display space. The optical lens converges light emitted by the illumination light source and emits the light into the reflector along a specific beam angle, the reflector is arranged on the upper part of the illumination support with the adjusting mechanism, and the light is reflected by the reflector and then uniformly projected on the surface of the exhibit. The height and the angle of the reflector can be adjusted so as to achieve the optimal state of the illumination requirement of the cultural relic exhibit. The reflecting illumination system for the showcase can be arranged on one side of the showcase, can also be arranged on two sides or can be arranged at multiple positions as required. The system has the advantages that the projected light is uniform, no light spot is generated on the surface of the cultural relic exhibit, the illumination light source is hidden in the cabinet body, and the exhibition space has no heat source, so that the exhibition illumination requirement of the cultural relic exhibit is met, the influence of the self-heating of the illumination light source on the life of the cultural relic exhibit is avoided, and the cost is low.

Fifth, detailed description of the invention

All of the features, methods, or steps in the processes disclosed in this specification may be combined in any combination, except features or steps that are mutually exclusive.

Any feature of the present specification may be replaced by another equivalent or alternative feature serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

As shown in fig. 1 and 2, a reflective lighting system for a showcase, wherein a safety glass shield (1) and a display platform (9) for placing cultural relics and exhibits are arranged at the upper part of the showcase, and a lighting bracket (4) is arranged on a cabinet body (8) made of metal material at the lower part of the showcase. The illumination light source (7), the optical lens (6) and the reflector (3) are mounted on the illumination bracket (4). The optical lens (6) converges light emitted by the illumination light source (7) and emits the light into the surface of the reflector (3) along a specific beam angle, the reflector (3) has a calculated arc section, the surface is provided with a high-reflection material coating, and the incident light is reflected by the reflector (3) and then is uniformly projected on the exhibition platform (9) along the reflection light range area (2).

The illumination light source (7) is positioned in the cabinet body (8) and is lower than the datum plane of the display platform (9) and completely isolated from the display space, and the optical shielding piece (10) with a reserved gap in the center is arranged at the upper edge of the optical lens (6), so that the excessive light can be effectively prevented from directly irradiating the eyes of visitors, and the appearance of the illumination system is beautified.

The illumination support (4) is provided with an adjusting mechanism, and the height and the inclination angle of the reflector (3) can be adjusted according to the requirements of the cultural relic exhibit so as to achieve the optimal state of the illumination requirements of the cultural relic exhibit.

As shown in fig. 2, the optical lens (6) constrains the light emitted from the illumination source (7) into a small included angle light band of the same length as the optical lens.

The illuminating light source (7) generating heat moves downwards to be hidden inside the cabinet body, and the showing space has no heat source, so that the showing and illuminating requirements of the cultural relic exhibit are met, and the influence of the heating of the illuminating light source on the service life of the cultural relic exhibit is avoided.

As shown in fig. 3, the reflective lighting system for showcase can be installed in multiple sets of systems on two sides or multiple locations of showcase according to the exhibition requirements of cultural relics.

The embodiments of the present invention have been described in detail, but the present invention is not limited to the embodiments described above, and it will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made herein without departing from the spirit and scope of the invention.
