In everyday life, fluorescent lamps and incandescent lamps using commercial AC power are most commonly used.

In the case of a luminaire, when the power is supplied and the lighting is easily installed, it can be installed anywhere. As the demand for lighting increases and its application fields increase, the load according to the overall power consumption increases day by day, and efforts are being made to reduce it.

The high-brightness LED device is a semi-permanent product with a lifetime of 100,000 hours, and is expected to replace future lighting due to low power consumption.

Currently, LEDs are mostly driven by a SMPS (SWITCH MODE POWER SUPPLY) or an adapter using a DC power source.In the case of driving LEDs with commercial AC power, a DC converter is required, and a passive device is used. In the case of circuit-configured products, the stability of driving LEDs is less.

LEDs generally have a long lifetime, depending on how they are driven. Factors that influence the lifetime are the LED's forward voltage (FORWARD VOLTAGE) and current (FORWARD CURRENT). High-brightness LEDs have a thermal runaway phenomenon, so it is difficult to guarantee long-term life with only forward voltage. To solve this problem, the constant voltage and constant current circuits must be configured stably.

When driving LEDs using existing SMPS or adapters, manufacturing costs are higher than expected. Focusing on solving these problems, the inventors have designed and applied a LED circuit that can be configured at a lower cost.

The present invention is designed to be installed anywhere in the presence of AC power in the form of a fluorescent lamp designed to use an array of high brightness LEDs connected in series for lighting and plugged into a commercial AC power source (110 [Vac] ~ 220 [Vac]). It is an AC-driven lighting device that constitutes a stable LED power supply circuit as a passive element in implementing various colors by dimming function and various LED combinations.

The present invention solved the problems of the existing technical LED by constructing a stable lighting device and a dimming function and a simple and semi-permanent device, and by using a commercial AC power easily, mushroom farm, flower planting facility, poultry farm It is easy to use as lighting fixtures for house, plant cultivation facility, department store show case, and other households, and it has a structure that is easy to install.

Adjust the amount of light by arranging multiple high-brightness LED arrays in series in the same color on a bar PCB (BAR) or by combining them in the form of one white LED + one blue LED (or two or three) in series. Set the values of passive elements R (resistance, 4000) and C (capacitor, 3000) so that proper current of 20 [mA] ~ 100 [mA] is required to drive LED connected in series. For reference, high brightness LEDs are driven at 3.6 [Vdc] / 20 ~ 60 [mA] for white, blue and green, and 1.9 [Vdc] / 20 ~ 60 [mA] for red. If you use an AC commercial power supply, you can burn the LED instantly without paying special attention to the power supply. In addition, the LED should not be damaged by static electricity when the power is on or off, and heat should not be generated in the LED and passive devices due to long-term use. It is to avoid.

A dimming function is attached to adjust the brightness of light according to the user's convenience, so that it can maintain a constant allowable illuminance (LUX) according to the place and growth conditions of living things. Especially in the case of mushroom farms, the roughness required for cultivation is known to be 200-500 LUX.

The device is designed to be waterproof by using a plastic or acrylic housing after mounting high-brightness LEDs in the form of rods or squares using PCBs, such as fluorescent lamps, for waterproofing.

If the PCB size of high-brightness LED is large, it will increase the manufacturing cost. Therefore, 30 [Cm] ~ 120 [Cm] is connected in series using several sizes of 30 [Cm] ~ 40 [Cm]. It is designed to make LED bars of various sizes.

High-brightness LED lighting apparatus according to the present invention for achieving the above object, the dimming unit 2000 for controlling the brightness of the LED module 6000 by controlling the phase of the commercial AC power supply (1000), the LED 20 [ Current control capacitor (3000) for supplying with limited current from mA] ~ 100 [mA], Cement buffer resistor (4000) for current control and circuit stabilization to remove static electricity generated when power on / off and prevent instantaneous current inrush Rectifier (5000) for changing the limited AC current to DC current through the current control capacitor (3000), high brightness LED lamp (6000) module for emitting light, and current control cement resistor (7000) as a stable additional current protection device. ) Is a lighting device for driving a high-brightness LED.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In Europe and Austria, 110 [Vac] ~ 120 [Vac] is used as commercial AC power source (1000), 220 ~ 230 [Vac], 50 [Hz] in USA and Canada, and 220 [Vac in Korea. ], 60 [Hz], commercial AC power is supplied as a different standard from country to country.

The present invention is a high-brightness LED lighting device that can be applied from 110 [Vac] to 220 [Vac], the dimmer 2000 for controlling the light brightness of the LED (6000) by driving the high-brightness LED (6000) of the microcomputer As a pulse width modulation (PWM) signal, a triac gate is driven to control an AC power supply (for the sake of convenience, a detailed internal circuit is not shown). In controlling the amount of dimming through the variable resistor, the microcomputer reads data through the analog to digital (A / D) converter and controls the AC power amount by turning on / off the gate of the triac element as a PWM (Pulse Width Modulation) signal. Power amount of LED peripheral circuit can be controlled.

The current control capacitor 3000 is a non-polar element that can flow current in both directions and is used as a limiting current of the LED-related peripheral circuit.

In the present invention, the capacity of the capacitor is added or decreased so that a current of 20 to 100 [mA] required to drive a high-brightness LED can flow.

The cement resistor 4000 for current control and buffer was used as a means to prevent inrush current generated when power is momentarily applied.

The rectifier 5000 is used as a means for converting an AC voltage into a DC power supply and supplying the high brightness LED. When the power is turned off, the rectifier 5000 also serves to prevent a reverse voltage generated from the capacitor 3000 and the high brightness LED.

The high brightness LED 6000 module is connected in series and is driven as a limited current supplied from the capacitor 3000. It provides a constant current through the current limiting circuit, so it can withstand a long time regardless of the high AC commercial power supply voltage.
