Underwater lighting {A UNDERWATER LIGHT}

The present invention relates to underwater lighting, more specifically, it is possible to control both by the program and the external controller by the microcomputer, to increase the heat dissipation efficiency by using a metal PCB, and to use the tempered glass as a front glass for durability It is about an underwater light that can be improved.

The lighting device using LED (Light Emitting Diode) has a low power consumption, high brightness and is not only visually beautiful but also has good readability.

In general, the fountain has a charm that gives the viewer a cool and aesthetic sense while spouting the high water of the sky.

However, a typical fountain boasts its best during the day, but because of the darkness at night, the fountain body cannot be easily observed, which causes the problem of its coolness and beauty.

For this reason, the lighting is installed in the fountain, which is the effect of the multi-colored light from the lighting at night to color the body of water while increasing the coolness of the body of water and the aesthetics of the multi-colored lighting.

Underwater lightings used in fountains, swimming pools, ponds, etc., emit light of multiple colors or monochromatic colors using LED bulbs.

By the way, the lamp using the LED bulb has a feature that generates a lot of heat, the LED is vulnerable to heat may be disconnected or melted the circuit board when overheated. In order to prevent damage caused by excessive heat generation, it is desirable to install the lamp so that it is always submerged in water. If the air level is low and the water level is low, the lamp is exposed to the outside and the cooling effect is reduced. Damage to the circuit may occur due to overheating.

In order to prevent the loss due to heat, it is necessary to check the water level at all times, which causes management trouble.

In general, in order to control several lamps, a control signal must be transmitted locally or by communication to each lamp through a distributor using an industrial PC. In order to use this method, the manager always had to stay in the field and produce the color directly. In addition, it requires a lot of equipment such as PCs, splitters, terminals, racks, and panels. Therefore, there was a problem that a lot of time and space is consumed in the installation of the control equipment.

On the other hand, in the case of using a PLC (Programmable Logic Controller), which has been widely used for lighting control, color control is performed by simply turning on / off power of a plurality of LEDs, and thus it is not possible to produce detailed color effects. Continuous program control was not possible, resulting in a lively lighting effect.

If the PLC is to be connected locally to produce various color effects, one switch must be connected to each LED, so the number of connecting cables can be so large that it can be almost impossible to control.

On the other hand, the LED bulbs installed in the lamp has a strong straightness of the light even when the installation of a multi-color bulb is separated from the color of each bulb is reflected to the outside, this has a problem that it is difficult to combine natural colors.

The present invention is to solve the above-mentioned problems, it is composed of a red-green-blue (RGB) three primary color LED, to provide a submersible lighting that can control the program by the built-in microcomputer and the external controller by DMX512 communication. The purpose.

In addition, the purpose of the present invention is to provide a submersible lamp that enables the expression of finer colors by introducing a constant current proportional control method.

In addition, by installing a light diffuser plate on the front of the LED is to provide an underwater light that allows the light from the three colors of LED to be naturally combined to give a uniform color of light.

In addition, an object of the present invention is to provide a submersible lamp that can minimize the damage of the circuit due to excessive heat by facilitating heat diffusion by manufacturing a PCB on which the LED bulb is installed with a metal material.

In addition, the present invention is to produce a protective glass for protecting the LED bulb made of tempered glass material to prevent the damage of the lamp, such as by impact, and to form a tapered engaging projection on the side of the protective glass to combine with the gasket elasticity of the gasket It is an object of the present invention to provide a submersible lamp that maintains close contact even when it is reduced so that the waterproof function can be exerted.

Hereinafter, with reference to the drawings will be described an underwater lighting (hereinafter referred to as "lighting") according to an embodiment of the present invention.

First embodiment

1 is a perspective view showing the structure of a underwater lighting lamp according to a first embodiment of the present invention, Figure 2 is an exploded perspective view showing the internal configuration of the underwater lighting lamp according to the first embodiment.

The first embodiment of the present invention has a structure that is fixed by its own support means without being coupled to the fountain nozzle.

As shown in FIGS. 1 and 2, the underwater lamp 100 according to the first embodiment is a stand 104 fixed to the bottom surface of the tank while supporting the housing 102 and the housing 102 of the upper part in which the light emitting device is accommodated. It is controlled in a state in which it is connected to the controller (not shown) for transmitting power and lighting control signal to the light emitting device.

An accommodation space of a predetermined size is formed inside the housing 102, and is open upward to emit light upward. Typically, the housing 102 is made of a metal material, but may be made of a plastic material resistant to heat or water.

The lower surface of the housing 102 is attached with a cable connector 118 through which the power cable and data cable are inserted.

A stand 104 having a column of a constant height is installed under the housing 102. A pedestal is installed at the bottom of the column to support the underwater light 100 from falling by the flow of water.

For a more robust installation, the pedestal may be secured to the floor with bolts or screws.

The housing 102 and the stand 104 are connected by a hinge 106. By the hinge 106, the housing 102 can be rotated by a predetermined angle while being able to emit light at various angles.

In the present invention, the angle is adjusted by one hinge 106, but by using two hinges will be able to emit light in the 360 degree direction even when the pedestal is fixed.

The lamp module 108 is seated in the accommodation space inside the housing 102. The lamp module 108 includes an LED 108a, a PCB 108b, a microcomputer (not shown), and an LED control chip (not shown).

The LED 108a consists of three types of LEDs that emit red light (R), green light (G), and blue light (B). Three colors of LED 108a may be installed one by one, but depending on the use condition, two LEDs 108a of the same color may be installed and the same color LEDs 108a may operate the same to make the light brighter. have.

The microcomputer emits light of various colors by emitting each LED 108a by an appropriate illuminance according to a control signal transmitted from the controller.

Typically, the illumination of the three types of LEDs 108a is controlled by adjusting the light intensity by 10 steps from 10% to 100%.

The PCB 108b is manufactured by mixing a metal and a ceramic material in order to effectively release heat generated from the lamp module 108. In the present invention, by adding aluminum (Al) having a high thermal conductivity, the PCB 108b may be manufactured to maximize the heat release rate. Heat generated in the PCB 108b is discharged to the outside through the side of the housing 102. By using the metal PCB, the temperature difference between the temperature of the LED 108a and the exterior surface of the lamp 100 may be within 15 ° C.

The microcomputer can operate according to its own built-in program software or can receive and operate a control signal from an external controller connected through communication. The type of control you choose will depend on your installation, usage and the presence or absence of an administrator.

Communication between external controller and microcomputer uses DMX512 communication method.

DMX512 communication standard is a lighting automation communication method that transmits information by transmitting data signal including device address to several devices connected in series. When using the DMX512 communication method, up to 512 control channels can be used, and the brightness of the light can be controlled in steps from 0 to 255.

In general, when adopting a PLC that is commonly used in lighting equipment, since only the on / off power of the power could be repeatedly adjusted, it is not only difficult to control the illuminance of the LED 108a step by step, but also several LEDs 108a. There is a disadvantage that too many cable terminals because each must connect a power line.

However, in the case of using the DMX512 communication method as in the present invention, the data cable and the power cable can be separated, and one controller can be collectively controlled without installing a switch or a relay for each bulb, thereby simplifying installation.

The microcomputer generates an operation signal according to the built-in program and transmits it to the LED control chip, and the LED control chip operates the LED 108a according to the transmitted operation signal. To this end, the LED control chip is preferably installed corresponding to each LED (108a).

The operation signal transmitted by the microcomputer may include information about illuminance, emission time, etc. of the LED 108a.

In the case of controlling the lamp 100 using an external controller, the controller transmits a control signal to the microcomputer. As described above, the communication between the controller and the microcomputer uses the DMX512 communication standard. The control signal transmitted from the external controller to the microcomputer is transmitted to the LED control chip, and the LED transmission chip operates the LED 108a according to the operating signal transmitted from the microcomputer.

Thus, by using the constant current proportional control method, rather than a simple power control method, detailed and complex control is possible, and a variety of effects such as rainbow production, wash, back wash, and fade effect are possible.

Since the method of controlling the operation of the LED 108a using the DMX512 communication method is a conventional method, a detailed description thereof will be omitted.

The lamp module 108 allows the LED 108a to face upward when fixed within the housing 102.

The lens cover 110 is installed above the lamp module 108. The lens cover 110 is a device that combines all the light emitted from each LED (108a) to the light of a single color to go out. To this end, in the present invention, a glass or acrylic light diffusion plate is used as the lens cover 110. The light emitted from the lamp module 108 is distributed to the entire lens cover 110 by the light diffusion plate, and the light is evenly mixed. Therefore, when viewed from the outside, each LED 108a does not emit light, but appears to be emitted from a light bulb of one color.

On the upper side of the lens cover 110, a disk-shaped protective glass 112 is installed. The protective glass 112 is a configuration for protecting the LED 108a and the lens cover 110 from external impact, and is preferably made of tempered glass material. In addition, by having a shape such as an opening formed in the housing 102, it can be tightly fixed.

The protective glass 112 may eliminate color deformation or distortion due to ultraviolet rays by using 8 mm thick tempered glass that is thicker than that used in the existing lighting fixture.

On the rim surface (side surface) of the protective glass 112, a coupling protrusion 112a of a predetermined length is formed. Figure 3a is a side cross-sectional view showing the structure of the protective glass, the engaging projection 112a is projected vertically from the border surface, the cross section of the engaging projection 112a has a tapered shape that becomes thinner and thinner as the distance from the border surface. .

The protective glass 112 has a thin disk shape, the gasket 114 is interposed on the edge (side) for waterproofing.

The gasket 114 is made of a resilient silicone material, and is manufactured in a ring shape to surround the edge of the protective glass 112. The inner side of the gasket 114 is formed with a groove on which the engaging projection 112a of the protective glass 112 can be seated.

The coupling structure of the protective glass 112 and the gasket 114 is mentioned later.

The ring-shaped fixing ring 116 is installed on the protective glass 112.

The fixing ring 116 of the metal material is tightly fixed on the upper edge of the housing 102 while compressing the edge of the protective glass 112 and the upper surface of the gasket 114.

The structure of the other configurations coupled between the retaining ring 116 and the housing 102 is shown in FIG. 3B.

As shown in FIG. 3B, the coupling protrusion 112a of the protective glass 112 is inserted into and fixed to the groove formed on the inner surface of the gasket 114.

The protective glass 112 surrounded by the gasket 114 is placed on the stepped upper portion of the housing 102, and the fixing ring 116 is fixed to the upper portion of the housing 102 while pressing the upper surface of the gasket 114.

If the cross section of the coupling protrusion 112a formed on the protective glass 112 is not a tapered shape and is rectangular, when the elasticity of the gasket 114 decreases over time in a state in which the coupling protrusion 112a is coupled to the gasket 114, the coupling protrusion 112a is coupled to the gasket 114. As the contact surface between the protrusions 112a opens, there is a risk that water may enter the housing 102.

When the cross section of the coupling protrusion 112a is tapered as in the present invention, even if a part of the gasket 114 is inferior in contact with the elasticity, the other part of the inclined surface may maintain the waterproofing while maintaining the contact.

Although the upper surface of the coupling protrusion 112a is illustrated in the drawings of the present invention, the lower surface (FIG. 4 (a)) or both surfaces (FIG. 4 (b)) may be tapered if necessary. There will be.

In this manner, the light emitting device is accommodated in the housing 102, and the inside and the outside of the housing 102 are waterproofed.

On the other hand, Figure 5 is a side view showing a rotating structure of the hinge.

As described above, the housing 102 is rotatably connected to the top of the stand 104, and rotated by a predetermined angle as shown in FIG.

Second embodiment

6 is an exploded perspective view showing the internal configuration of the underwater light according to the second embodiment of the present invention, Figure 7 is a plan view and a side view showing the structure of the underwater light according to the second embodiment.

The second embodiment of the present invention is a case in which the underwater lamp 200 is used in combination with the fountain nozzle, which is different in that it does not require the stand 104 structure as in the first embodiment.

Since the underwater lamp 200 of this structure should be fixed in a state where the fountain nozzle is fitted, the through hole 218 into which the nozzle is inserted is formed in the center portion.

The underwater lighting lamp 200 according to the second embodiment is also provided with a housing 202 having a receiving space therein, a lamp module 204 is installed inside, the lens cover 206, the protective glass 208 on the upper side , The fixing ring 214 is installed.

Through-holes are formed in the centers of the housing 202, the lamp module 204, the lens cover 206, and the protective glass 208, and the centers of the respective through-holes all lie in a straight line.

The configuration of the lamp module 204, the function of the lens cover 206, the material of the protective glass 208, and the like are the same as those of the underwater lamp 100 described above, but there are slight differences in the gaskets 210 and 212. .

In the previous underwater light 100, the gasket 114 only needs to be fitted to the rim surface because there is no through hole in the center portion of the protective glass 112, but in the second structure, the gasket 114 is waterproof even in the through hole formed in the center of the protective glass 208. The gasket needs to be inserted.

Therefore, the outer gasket 210 is provided on the edge of the protective glass 208, and the inner gasket 212 is installed on the inner side of the through hole.

The bottom surface of the inner gasket 212 is in close contact with the top surface of the through hole protruding from the bottom surface of the housing 202 by a predetermined height. The upper surface contacts the bottom surface of the through hole formed in the center of the protective glass 208. Therefore, even when the fountain nozzle is fixed through the underwater lamp 200, water does not enter the inner surface of the through hole.

And the cable connector 216 is installed on the lower surface of the housing 202.

The underwater light 200 according to the second embodiment is fixed directly to the fountain nozzle, and thus does not require a stand or hinge structure.
