Description

LED lamp with far-infrared emission and light intensity control functional paints {LED lamp with germanium and photometric adjustable functional paint}

The present invention relates to an LED lamp using a far-infrared emission and light intensity control functional paint, and more particularly, to maintain a clean and beautiful appearance and installation state, and solves the prevention of light leakage at the corners inside the slim frame. At the same time, it has a structure that greatly simplifies assembly, and uses germanium pozzolan and light control functional paint to emit far infrared rays in double, and at the same time, LED light using far-infrared emission and light control functional paint to control light intensity. It is about.

Today, various types of lamps are used to provide light or illuminate an object at night or in a dark room.

In particular, lighting lamps using a light emitting diode (Light Emitting Diode) as a light source has a lower power consumption than incandescent lamps and fluorescent lamps, and saves energy, and is solid, long-lasting and environmentally friendly as a solid point light source unlike conventional light sources. Due to its characteristics, there is a considerable advantage in terms of maintenance.

However, a light lamp with a simple combination of light emitting diodes emits optically clear monochromatic light, causing unpleasant glare and eye fatigue to the user. Therefore, when used as a direct light or an indirect light for directing an indoor atmosphere, it is possible to have a light distribution suitable for the purpose. Proper lens or light guide plate coupling is important.

In recent years, by keeping the distance between the light emitting diode and the light guiding plate appropriately, the light of the point light source generated from the light emitting diode is changed into the light of the surface light source (the light source having the diffused portion in the plane) through the light guiding plate. LED flat lamps have been developed in various forms, replacing existing fluorescent lamps.

Such LED flat lamps are generally classified into edge-lighting and direct-lighting according to the method in which the light emitting diodes are arranged and the direction in which the light is directly and emitted.

In the former case, the slimmer product is advantageous due to the relatively thin thickness, but there are disadvantages in the increase in weight due to the decrease in brightness and the light guide plate. In the latter case, when the thickness of the product is reduced, the LED dot appears on the light emitting surface. There is a limit in slimming because a separate space is required to use the supply unit (SMPS).

Recently, power circuits have been developed on the same PCB as LEDs to reduce the thickness and simplify the installation process.However, due to the short life of the power circuit, the entire product must be replaced. As a result, the result is contrary to the long life characteristics of the product. Therefore, it is not only a long life characteristic but also a thin side emitting type product is in the spotlight.

Recently, as a way to solve the above-mentioned disadvantages of fluorescent lamps, lighting fixtures using LEDs (Light Emitting Diodes) have been developed, and the market share is gradually increasing. LED lighting fixtures can be energy-saving design with adequate illumination, long life, and no flicker due to the use of DC power.

In addition, the LED lighting fixture is environmentally friendly as it does not use environmentally harmful substances.

Indoor LED lighting fixtures are manufactured in various forms, but most LED lighting fixtures are manufactured in the form of square flat plates.

Typically, a lighting plate in which a plurality of LED modules are mounted is built in a rectangular metal frame, and a light transmissive panel is coupled to the front of the metal frame for the purpose of dispersing and decorating the light of the LED module.

Here, the metal frame has a structure in which four bar-shaped border frames are coupled. By the way, by assembling at least two or more bolts to the portion where each of the rim frame is coupled, a lot of time is required for assembly work.

On the other hand, the LED module is superior in brightness than fluorescent lamps to be more thoroughly manufactured to prevent light leakage at the corner of the luminaire frame. Conventionally, a light leakage preventing member is coupled to a corner portion to prevent light leakage of a flat panel LED lighting fixture, and Korean Patent Registration No. 10-0975563 discloses such a configuration.

Referring to the above prior document, the light leakage prevention portion for blocking the light leakage is provided in the connection member for connecting the frame member of the lighting fixture to each other. However, the prior document has a problem in that the assembly of the frame is cumbersome as the coupling blade is formed in the coupling portion of the connecting member and has a complicated configuration for assembling the frame member, and light leakage occurs due to component tolerances of the connecting member. have. In addition, after assembling the connecting member and the frame, a number of bolts are required at each corner, and thus there is still a problem that a lot of time is required for assembly work as in the conventional light leakage preventing structure.

In one embodiment, the present invention provides 25 to 40% by weight of an aqueous ethylene vinyl acetate resin, 20 to 30% by weight of water, 10 to 15% by weight of calcium oxide, 10 to 10% by weight of anion and far-infrared rays, to facilitate deodorization and antibacterial activity. It is also possible to further apply an environmentally friendly paint containing 15% by weight, 5 to 10% by weight of lime powder, 1 to 5% by weight of iron oxide, 10 to 15% by weight of elvan and quartz.

The paint for controlling the brightness and illuminance is coated on the light guide plate unit to activate the light emitted from the LED light to increase the illuminance, and also has a retroreflective function to control the light and illuminance, and to increase the illumination and discoloration stability, It has excellent retractive reflection function and light and illumination control.

According to the present invention, the weight ratio of the light control functional paint and germanium is 50 wt%: 50 wt%, which causes the secondary light to be emitted from the light guide plate unit 3 coated at a ratio of 50 wt%, thereby causing various diseases by thermal action of far infrared. It helps to get rid of the blood vessels, expands the capillaries and helps blood circulation, which not only has a beneficial effect on the body, but also removes heavy metals, sleeps, deodorizes, prevents mold growth, and purifies the air.

In addition, the present invention, by mixing and coating a germanium pozzolanic and light intensity control functional paint in a constant ratio on the light guide plate unit to not only activate the light emitted from the LED lighting, but also to reflect down to increase the light efficiency.

Therefore, the present invention primarily emits far infrared rays through the germanium layer 2 on the inner surface of the metal unit 1 while reflecting and diffusing the light projected from the LED module several times, and then the weight ratio of the light control functional paint and germanium is In the light guide plate unit 3 coated at a ratio of 50% by weight to 50% by weight, far infrared rays are emitted secondarily, and when radiated to the human body through multiple emission of anions and far infrared rays, various beneficial effects are exhibited.

In addition, the present invention can solve the light leakage prevention phenomenon without using a separate corner light leakage prevention member by reinforcing the corner fastening portion.

On the other hand, the inner surface of the metal unit 1 may be coated with a far infrared ray emitting germanium layer 10 to 20 microns.

If the far-infrared emission germanium thickness is 10 microns or less, the amount of various wavelengths that are beneficial to the human body is rapidly reduced, and the amount of far-infrared rays is radiated in small amounts to collide with the germanium on the metal unit 1 to reduce the amount of wavelengths that are reflected.

Far-infrared emission When the germanium is 20 microns or more, the second-infrared emission is emitted in large quantities, but the coating layer is thick, so that the amount of reflection reflected by the metal unit 1 is reduced and the amount of emission of various wavelengths reflected by the collision with germanium does not increase in proportion to the thickness. there is a problem.

In addition, the light intensity control functional paint and germanium may be mixed on the surface of the light guide plate unit 3 in a predetermined weight ratio to coat 7 to 20 microns.

The reason for limiting the thickness of the surface coating material of the light guide plate unit 3 is not only to increase the illuminance by activating the light emitted from the LED light, but also to have a retroreflective function to control the light and illuminance, and also to emit a large amount of far infrared rays. There is an advantage.

When the surface coating material of the light guide plate unit 3 is 7 microns or less, the sharpness decreases and it is difficult to maintain roughness above a predetermined value.

On the other hand, when the light intensity control paint is 20 microns or more, the sharpness is very good, but there is a problem that the sharpness does not continue to increase in proportion to the thickness.
