The present invention relates to a light emitting diode lighting device for a museum exhibition stand, and more particularly, an apparatus for effectively performing a lighting of a museum exhibition table at various color temperatures by using a lighting device in which two or more light emitting diodes emitting light at different color temperatures are alternately arranged. The present invention relates to a device that can increase the aesthetics of the viewers and at the same time prevent the exhibits from being damaged by light or heat.

A light-emitting diode (LED), generally called a light emitting diode, refers to a light emitting diode device, and is a device using a phenomenon in which light is generated when a current flows through a PN junction of a compound semiconductor such as GaP or GaAs. In manufacturing, a light emitting diode that generates light having a predetermined wavelength may be manufactured by adjusting the component ratio of the semiconductor compound.

In particular, since the light emitting diodes have a relatively low power consumption and very bright brightness and do not involve high heat during light emission, these light emitting diodes have been widely applied to traffic lights, vehicle rear lamps, and outdoor advertisements. Its scope is not limited.

In addition, the lighting technique of art galleries / museums differs depending on the contents of the exhibition. In the museum, appreciation is the main subject, while in the museum, observation and research are the subjects.

As a result, museums aiming at appreciation express the exhibits more favorably, while museums aiming to observe or investigate research are focused on expressing the form, color, and texture of the exhibits.

In order to create a comfortable visual environment suitable for the purpose, it is necessary to examine illumination, luminance distribution in the field of view, glare, shadow, modeling, and color temperature, which are light colors of the light source.

In particular, museum lighting is different from general lighting, and it is important to protect the exhibits and prevent damage.These damages are caused by radiation, light, temperature, air pollution, etc. Consideration should be given to the effects of radiation.

Artificial light used for the exhibition stand of the museum is required to have a warm color with a low color temperature rather than close to the main daylight color, and the recommended color temperature of the light source used in parallel with the recommended illuminance for the exhibit.

However, it is difficult to control the color temperature of the existing museum exhibition stand, and in general, since high temperature is accompanied by light emission, it is difficult to prevent the damage of the exhibits due to light and heat, and it is difficult to illuminate the exhibits with an appropriate color temperature. There was this.

The present invention is to solve the above problems, by using a lighting device in which two or more kinds of light emitting diodes emitting light at different color temperatures alternately arranged to perform lighting at least three or more color temperature, lighting the museum exhibition stand The present invention is to provide a light emitting diode lighting device for museum exhibition stand that can effectively perform at a variety of color temperature to increase the aesthetics of visitors and prevent damage to the exhibits by light or heat.

The present invention is an apparatus for illuminating a museum exhibition stand, a plurality of light emitting diodes arranged side by side on a substrate at a predetermined interval; A transparent pipe accommodating the light emitting diodes; A stopper formed of silicon laminated between two layers of rubber plates to seal both ends of the transparent pipe; A power control unit for controlling a power supply of a power line connected to a substrate through the plug for turning on the light emitting diode; It is achieved by constructing a cradle that horizontally positions both ends of the transparent pipe to the upper side of the museum exhibition stand so that the light emitting diodes face downward.

The transparent pipe 20 is molded to be somewhat longer than the overall length of the substrate 11 on which the light emitting diodes 10 are arranged, thereby closing both openings with a stopper 30.

In this case, the stopper 30 is formed by laminating the silicon 32 between two layers of rubber plates 31 as shown in FIGS. 2 and 3, and the diameter of the stopper 30 is the inner diameter of the transparent pipe 20. It is preferable to maintain the airtightness of the transparent pipe 20 by forming it somewhat larger and inserting and fixing it in the transparent pipe 20 by applying a force to the stopper 30.
