Description

[0001] Multi-purpose smart lighting devices [

The present invention relates to a versatile smart lighting device, and more particularly, to a versatile smart lighting device that can diffuse diffused light and concentrated light according to a use through various combinations of positions of individual lighting units.

In general, incandescent lamps, fluorescent lamps, and triple-wavelength lamps have been used as lighting devices. However, since the life span is short and energy is consumed in a large amount, ultraviolet rays harmful to human bodies are detected in the emitted light and argon gas and helium gas The environmental pollution problem is also serious.

Recently, in consideration of power consumption, lifetime of illumination, brightness, diffusion range, etc., the use of an illumination device using a light emitting diode (LED) as a light source has been increasing.

Lighting using LEDs can be applied to indoor lighting (bedroom, living room, study room, etc.), landscape lighting (buildings, bridges, Art museums, theaters, resorts, etc.), IT appliances and automobiles, store interior and display, and light therapy lighting.

The above-described LEDs are more expensive than the existing light sources and have a high initial investment cost, and it is difficult to develop the light as well as the diffusion. However, since the price of the LED device is going to be lowered in the future, the lightness of the components, simplification of the manufacturing process, If it is improved, demand and applications of LED lighting are expected to increase significantly.

In addition, modern lighting seeks not only to illuminate the light but also to incorporate the interior and artistic features of the building, creating a new market by combining imagination and creativity through scientific design.

Meanwhile, in order to maximize the lighting effect according to the surrounding environment such as installation place and position, it is preferable that the lighting device using the LED is irradiated with light in a certain area. For this purpose, So that light can be irradiated to a desired area.

Such a lighting apparatus includes a lighting unit and a bracket for mounting a lighting unit to the fixing member, and the lighting unit is fixed to the bracket after the lighting unit is adjusted to a desired angle.

However, in the lighting apparatus having the angle adjustment of the prior art, since the bracket is a structure in which the lighting unit is simply bolted, the fastening force of the bolt may be deteriorated by an external physical impact. In this case, the angle of the lighting unit coupled to the bracket may not be maintained and may be shifted to a direction parallel to the horizontal plane by turning at an angle with respect to the horizontal plane. In particular, the heavier the weight of the lighting unit, the greater the frequency of such problems.

In addition, in the case of the conventional art, the angle of the illumination unit can be set only at the initial installation, and in order to adjust the angle again, there is a problem that the operator has to input the angle by using the tool.

In addition, the prior art is structurally problematic in that the illumination unit is fastened by a bolt, which is poor in appearance, difficult to control the concentration and diffusion of illumination, and difficult to automate the angle control of illumination.

First, the illumination array 100 is provided with a plurality of illumination units 120 in the longitudinal direction in a rectangular frame having flexibility.

The frame 140 of the illumination array 100 is preferably made of stainless steel and is preferably formed in a vertical direction in a space where gravity acts. Accordingly, when the center portion of the illumination array 100 is fixed by the fixing bar 300, the both ends are naturally bent in the vertical direction, and the first motor unit 500 and the first wire unit 700 So that the bending radius can be adjusted.

Here, the frame 140 may be selected from stainless steel 304, stainless steel 304 contains nickel, has excellent corrosion resistance and heat resistance, has a low temperature strength, and has good mechanical properties and can be suitably used in the present embodiment.

In the illumination unit 120, a plurality of RGB LEDs 122 may be arranged in a dot matrix to selectively emit a plurality of colors. The lighting unit 120 can perform lighting functions for various purposes through various colors and brightness production, and can be used as a three-dimensional display display or an art design by avoiding conventional uniform lighting. At this time, if the plurality of RGB LEDs 122 arranged in the dot matrix are wrapped with polycarbonate, light emission can be performed, thereby exhibiting another illumination effect.

Further, a plurality of the illumination arrays 100 may be arranged and used variously according to functions of an indoor space or an illumination, and each illumination array 100 operates independently of each other to enable various illumination production.

Next, the fixing bar 300 allows the illumination array 100 to be supported at a predetermined height. One end of the fixing bar 300 is fixed to the center of the illumination array 100, and the other end thereof is fixed to the ceiling of the structure. Here, the fixing bar 300 is preferably made of a steel material having high rigidity so as to more firmly support the illumination array 100.

The fixing bar 300 is fixed to the central portion of the lighting array 100 rather than simply supporting the lighting array 100 to thereby form the lighting array 100 through the organic connection with the first wire portion 700 and the second wire portion 720, The bending radius of the base 100 can be variously adjusted.

Next, the first motor unit 500 includes a pair of step motors installed in the ceiling corresponding to the positions of both ends of the illumination array 100. As can be seen from FIG. 3, the rotation shaft of the step motor can be fully engaged to facilitate winding and unwinding of a wire to be described later. The rotation movement of the motor through the wire connected to the pulley It is possible to switch to linear motion. At this time, it is preferable to measure the moving distance through the rotation of the motor and optimize the diameter value of the pulley in order to minimize the error range with respect to the vertical movement of the wire.

The step motor rotates by a predetermined angle every time a pulse signal is supplied. Since the number of input pulses is completely proportional to the rotation angle of the motor, the rotation angle can be accurately controlled. These step motors are designed so that two coils are wound on a stator made by stacking iron plates to form two pole pairs, and the N poles and the S poles of each pole pair face each other. And the teeth integrated in the stator are distributed to function as a pole wheel.

Next, the first wire portion 700 is composed of a pair of step motors and a pair of wires connected to both ends of the illumination array 100, The upper and lower lengths of the wires of the wire can be varied individually or simultaneously. That is, the wire is wound or unwound on a pulley mounted on a rotary shaft of a step motor to vary the vertical length.

Here, the wire is preferably made of a metal wire for securely supporting the illumination array 100, and in particular, the steel wire and the maracas are twisted together to increase the durability, thereby further improving the stability.

In addition, Arduino is relatively inexpensive compared to other modules, and supports various operating systems such as Windows, Mac OSX, and Linux, and since Arduino's circuit diagram is released according to CCL, anyone can directly create and modify the Arduino board . In particular, by utilizing the excellent compatibility with the operating system of the smart device, it is possible to easily control the peripheral devices such as the step motor by using the short distance communication with the Bluetooth or the NFC to provide the interactivity with the surrounding environment.

The drive driver 940 includes a motor LED 941, a 5V LED 942, a variable resistor 943, motor power connectors 944a and 944b, a motor control connector (not shown) 945, and step motor connectors 946a, 946b.

The motor LED 941 and the 5V LED 942 are electrically connected to the power supply voltage for driving the stepping motor so that the brightness of the LED is changed when the power supply voltage is shaken. This makes it easy for the user to know whether there is a power failure.

The variable resistor 943 is used to adjust the amount of current supplied to the stepper motor. The variable resistor 943 can adjust the current according to the heat of the stepper motor and the step-out state.
