Description

LED cluster of light emitters {a lamp structure of LED array.}

LED light emission is made by solid state electroluminescence, and it is possible to realize relatively high luminance with long life by low voltage and small current, and it is a light source with relatively low heat generation. Is rapidly replacing.

LEDs have a light emission color close to a single wavelength, and the color of light emitted by these LEDs appears as a transparent and beautiful color tone that gives a clear feeling, and distinguishes them from conventional light sources.

The present invention relates to the structure of an LED lighting lamp having such a useful feature and can be expected to have a unique interior effect from the cluster of small point light sources and the beautiful luminous color.

The LED is a light source close to a single wavelength that is relatively low power, and when used as a lamp, a plurality of LEDs can be clustered to emit light to obtain necessary illuminance. Recently, high output LEDs with injection currents ranging from 350mA to several amperes have been introduced. However, this high output LED has a high brightness and a higher brightness point light source, which is accompanied by an increase in power consumption. Therefore, the contrast between the light source and the surroundings is large, and therefore, the problem of glare and the light distribution of the LED due to the narrow viewing angle Due to the increasing number of difficult tasks such as problems, it is often advantageous to construct a luminous body by clustering a plurality of medium output LEDs of 100 mA or less in a daily living environment or a residential environment, compared to the application of a high output LED.

Conventional LED lighting has been generalized as a light source that replaces conventional fluorescent tubes or downlight fluorescent lamps or halogen lamps. Therefore, conventional LED lamps are not directly distinguished from conventional fluorescent lamps or halogen lamps because they have a structure directly compatible with those of fluorescent lamps or halogen lamps, or reproduce the light emission hue of the visible light region and the diffusion effect of phosphors. It has been put to practical use as a tendency to realize a dimming performance. However, LEDs emit light based on a completely different principle from fluorescent lamps, which can be compared to the fact that incandescent lamps of the past had a completely different principle from fluorescent lamps. Therefore, LED does not simulate the dimming characteristics of fluorescent lamps, but can be used for lighting as a unique light source and has a unique beauty.
