Description

Discoloration filter device for LED light

The present invention relates to a color change filter device applied to an LED (Light Emitting Diode) lighting lamp, and if described in more detail, the LED lighting lamp is easily changed by changing the color of the LED light emitting light of a single color. The present invention relates to a color change filter device for LED lighting that allows it to emit in various colors.

In general, LED lighting is installed to supply power to the LED module by the LED holder by attaching and fixing a heat sink to the rear of the LED module where the LED is installed on a printed circuit board to emit light according to power supply. A reflective shade or diffuser lens was installed in front of the building and fixedly installed on the ceiling or wall.

As an example of a conventional LED lighting lamp, as published in Korean Utility Model 2009 No.8709 (published on August 28, 2009), the heat dissipation board is in contact with the lower part of the circuit board on which the light emitting diode chip is installed, while the front of the LED is in contact. Various lenses can be installed by selecting to adjust the irradiation direction and irradiation range of light, and thus, the light can be controlled efficiently, but according to this, the direction and range irradiated from the LED only by replacing the lens, etc. It was only able to adjust the LED light itself, and had the disadvantage of not being able to express variously the contrast, color clarity or color sense of the irradiated object according to the color change of the LED light itself.

Accordingly, in order to diversify the color of the LED lighting, it is produced by coating a transparent material having a color in front of the LED of the LED module, or in the front of the LED module as published in Korean Patent No. 1378908 (announced on March 27, 2014). The technology of installing a blocking window on the front of the reflective shade was developed, so that the glass of the blocking window could have a color so that the LED light could emit in various colors, but coating the LED module is to order an LED module with a specific color. Since it had to be manufactured, it was quite expensive and had a problem of increasing the manufacturing cost.The size of the colored glass and colored lenses on the front of the reflector increased, and the load increased. As the manufacturing cost increased, it was located in the front of the lamp, the tip of the reflector. There was a problem in that various insects or foreign substances were introduced into the interior, so that the color change of the LED lighting could not be performed smoothly.

As previously published in Korean Patent Publication No. 85908 (published on July 8, 2014), an annular protrusion bonded or screwed to the front of the chip board on which the LED is installed is provided to form a spherical skin and a flange at the edge. A technology has been developed to fix the formed illumination color conversion lens to be interposed between the annular projection and the lens holder by the lens holder.Therefore, the size of the lens was reduced and installed directly in front of the LED module to solve various problems. , Since the lens for lighting color conversion has a color and is manufactured to have a thin and flat flange at the edge of a spherical skin with a bulging center, the lens is expensive and takes a long time to manufacture, and it can be applied to the LED module used in the existing LED lighting. It had a number of problems, such as not having it.
