Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a traffic display device which is used, for example, as a signal light for urban traffic, and uses a semicircular diurnal luminescent light source that simultaneously emits light in three primary colors (blue, yellow) as a light source. Regarding.

i. jM spheres are set respectively and placed in the reflex theory, and color lenses of red, green, and 1゛ξ are set at R'+f of this reflector, respectively, and 174 hl- is set. .

[Background technology ii': J point]

However, since the light bulbs constructed in this manner use electric bulbs or fluorescent lamps as light sources, the power consumption is extremely large and uneconomical. In addition, since signal lights for urban transportation in particular are installed outdoors where the environment such as temperature and crystallinity changes rapidly, defects such as the filament 1 whistle wire of the light bulb are likely to occur, which limits the lifespan of the light source. .

On the other hand, in order to deal with such problems, it has been considered to use a light source in which a large number of light emitting diodes are connected in 1h rows. However, if a large number of light emitting diodes are all connected in series with their polarities changed (1)i, it often takes up 1iii1 during assembly, and, for example, if any one diode In this case, all diodes cannot emit light.
This results in a lack of reliability.

[Purpose of the invention]

This invention was made to solve the above-mentioned problems. For example, even when used for a long period of time under conditions where the boundaries of a castle change rapidly, the lifespan of the light source is not limited and the light source can be used for a long period of time. The purpose of the present invention is to provide a highly reliable traffic display device that can be used in traffic.

[Summary of the invention]

In other words, the variable JD display device according to the present invention uses a semiconductor white light emitting device with polarity 'J! The light emitting element circuit connected in parallel in 14 relationships is supplied with alternating current pressure of commercial frequency 7Bj, Vi, and the white light emitted by the upper Wd light emitting element is converted into mourning-colored light.
< This is a filter that allows the light to pass through.

〔Effect of the invention〕

As described above, according to the present invention, by using a plurality of semi-central light emitting elements as a light source, it is possible to effectively change the environment. Even in the case where J1r'n' is used against J1r'n', it can be used with low consumption'1-1i power without limiting the life of the Tsukoko body, and is it cost-effective?
