Description

LED lamp and load control system to control it

The present invention relates to an LED lamp and a load control system for controlling the LED lamp, and more particularly, an LED lamp applicable to a fire fighting or dimming facility having an LED module divided into at least two groups and an SMPS corresponding to each group. A load control system for controlling the load of the LED lamp.

Load control means that the power company and the customer enter into an agreement to effectively suppress the peak load in preparation for the system accident of the power company, and when the peak load occurs, the power company controls the power usage equipment of the customer by the time and the number of the agreement. Say that.

At the national level, load control maintains power quality by securing an adequate reserve rate, stabilizes power prices, and reduces facility investment and operating costs through efficient operation of power generation facilities and energy resources. In addition, the load control has the advantage that the electric bill is reduced in terms of the customer, and systematic power management is possible by establishing an optimal load management system.

However, various technologies are currently proposed to control the load of customers, but it is difficult to find a case where the technology is actually applied.

In addition, in the case of the existing fire fighting equipment when the power supplied from the outside, there is a problem that the fire fighting equipment is not controlled even if the communication technology is applied. In addition, in the case of the indicator or emergency light (or induction light) applied to the existing fire fighting equipment there is a problem that it was not intuitive to recognize whether a general fire occurs. In particular, in case of seedling, the general public cannot recognize whether a fire has occurred due to external noise.

In addition, if the communication technology is applied to the dimming equipment, the product cost increases, and the construction cost also increases. In addition, malfunctions due to lack of communication technology and dimming control of the current and voltage of the whole LED module in SMPS cause LED CHIP brightness deterioration, flicker phenomenon and CHIP performance deterioration, and the lifespan is shortened by stress caused by SMPS control function. . Therefore, there is a need for a method of controlling the LED module by a method other than communication control.

The problem to be solved by the present invention is to propose a method for reducing the maximum power consumption of the consumer.

Another problem to be solved by the present invention is to reduce the maximum power consumption of the customer, to propose a method for reducing the customer's electricity bill.

Another problem to be solved by the present invention is to propose a method for maintaining the power quality by securing an appropriate reserve ratio.

Another problem to be solved by the present invention is to propose a method for reducing the power consumed in the LED lamp.

Another object of the present invention is to propose a method of reducing the cost of replacing the LED lamp when some of the LED module constituting the LED lamp is defective.

Another problem to be solved by the present invention is to propose a light or an emergency light (or induction light) that the general public can intuitively recognize whether a fire occurs.

Another problem to be solved by the present invention is to propose a method for controlling the LED module using a method other than the communication control method.

To this end, the load control system of the present invention is a time-based start time point, which is a specific time point based on a power usage facility, a meter for providing the power used in the power usage facility in a pulse form, and the power consumption in the pulse form provided by the meter. It includes a load control terminal that calculates the predicted power that is expected to be consumed in the demand time period when the end of the demand time based on the current power, the current power used to date, the amount of power changes per unit time.

The load control system and the LED lamp according to the present invention use the predicted power and the adjusted power measured by the load control terminal to control the power used in the customer's power equipment. In this way, by controlling the power used in the power use facilities to reduce the maximum power consumption of the customer, there is an effect of reducing the customer's electricity bill.

In addition, the present invention has the effect of maintaining the power quality by ensuring a suitable reserve ratio, in particular reduces the power consumed in the LED lamp. That is, the LED module constituting the LED lamp may be divided into at least two groups, and the power used in the LED lamp may be reduced by turning on / off the LEDs for each LED module. In addition, when some of the LED modules constituting the LED lamp is defective, it is possible to reduce the replacement cost of the LED lamp because only the group containing the module needs to be replaced.

In addition, by applying the LED lamp proposed in the present invention to the fire-fighting equipment, it can be used as a function of a lighting lamp in normal times, and can be used as a function of an induction lamp or an indicator light in an emergency, and the applicable place is also available in public places such as schools, government offices, subways, etc. It can be applied to the downlights and the purchase used. In addition, the LED lamp of the present invention can be applied to high ceilings, explosion-proof lamps of factories, and can be applied to lamps, street lamps and sports lights in tunnels.

The foregoing and further aspects of the present invention will become more apparent through the preferred embodiments described with reference to the accompanying drawings. Hereinafter will be described in detail to enable those skilled in the art to easily understand and reproduce through this embodiment of the present invention.

1 is a block diagram showing the configuration of a load control system according to an embodiment of the present invention. Hereinafter, a configuration of a load control system according to an embodiment of the present invention will be described in detail with reference to FIG. 1.

According to FIG. 1, the load control system includes an external server, a load control terminal, a monitoring terminal, a meter, and a power use facility. Of course, other configurations in addition to the above-described configuration may be included in the load control system according to an embodiment of the present invention.

The power usage equipment 100 is driven by receiving power from the outside, and the used power is provided to the load control terminal 300 through the meter 200. In addition, the power usage facility 100 is determined whether to drive according to the control signal of the load control terminal 300. That is, the power usage equipment 100 is driven according to the on / off signal of the load control terminal 300.

The meter 200 extracts information on power used by the power usage facility 100 of the customer. The meter 200 provides the load control terminal with information on the amount of power used in the form of a pulse. That is, the meter 200 provides a power amount pulse and a synchronization signal to the load control terminal 300.

The external server 400 is a server managed by a power company that supplies power. The external server 400 communicates with the load control terminal 300 and provides necessary information to the load control terminal 300 or receives necessary information from the load control terminal 300.

The monitoring terminal 500 is a terminal managed by the customer. The monitoring terminal 500 communicates with the load control terminal 300 and receives necessary information from the load control terminal 300. The monitoring terminal 500 provides a target power to the load control terminal 300. Hereinafter, the operation of the load control terminal 300 will be described in detail.

The load control terminal 300 stores the demand power, the predicted power, the target power, and the reference power for 15 minutes of the customer. The load control terminal 300 stores the voltage, current, power factor, and apparent power consumed by the customer. The load control terminal 300 provides the stored information to the external server 400.

The load control terminal 300 calculates the current power by using the power amount pulse provided from the meter 200. This will be described later.

The load control terminal 300 controls the driving of the power usage equipment by using the calculated demand power, target power, and predicted power. That is, the load control terminal 300 blocks the driving of the power use facility when the demand power is higher than the reference power. To this end, the load control terminal 300 calculates demand power in real time.

Power demand means the average power within the demand time, which is calculated by calculating the amount of power used within the demand time limit.

P: power demand

W: power consumption

H: demand time

In general, the demand time is based on 15 minutes, and therefore Equation 1 is expressed as Equation 2 as follows.

The power of Equation 2 is called the demand power, and the maximum value of the 15-minute power demand for one month is called the maximum power demand.

2 illustrates the concept of maximum demand power.

According to Fig. 2, the demand power for one month is displayed, and in particular, the maximum demand power with the maximum demand power is shown.

In general, the electricity bill consists of a basic fee and a usage fee, and the basic fee is charged with the largest maximum demand power using the demand electric power in July, August, September, and the current month. Therefore, when the maximum demand power is large, the base rate also increases proportionally. In other words, the maximum demand power is a standard for establishing a basic charge for one year, and thus there is a problem in that a high electric charge is paid even when the maximum demand power temporarily increases. In order to solve this problem, a method of lowering the maximum demand power to the target power is required.

Hereinafter, a method of reducing the maximum demand power to the target power will be described.

3 illustrates a graph including a predicted power, a target power, and a reference power according to an embodiment of the present invention. Hereinafter, the concept of each power and a method of lowering the maximum demand power below the target power will be described with reference to FIG. 3.

The load control terminal receives a signal from the meter and calculates the reference power and the predicted power, the current power, and suppresses and distributes the maximum demand power so that the current power can be maintained below the target power. In addition, the load control terminal manages the maximum demand power by applying a control method suitable for the customer by using various control algorithms.

The load control terminal calculates the current power Pt by counting the number of active power pulses provided from the meter. The load control terminal calculates the predicted power Q using the current power, the reference power Pr, and the remaining demand time. The load control terminal calculates the adjusted power U by using the predicted power Q, the target power R and the remaining demand time. The load control terminal provides information on target power, current power, and predicted power to an external server or a monitoring terminal.

Hereinafter, a method for calculating each power will be described in detail.

1. Reference Power (Pr)

It refers to the power of the current demand time in the powers with the shortest distance from 0 to the target power.

Reference Power = (Target Power / Remaining Demand Time (sec)) * Elapsed Time (sec)

2. Current power (Pt)

The amount of power used up to the present after the start of the demand time limit.

Current power = (synthetic denaturation ratio / pulse integer) * integrated pulse number * (60 / demand time (minutes))

Synthetic Denaturation Ratio: CT Ratio * PT Ratio

CT ratio: primary voltage / secondary voltage

PT ratio: primary current / secondary current

Pulse integer = number of pulses output per KWH

3. Predictive Power (Q)

It is the amount of power expected to be reached at the end of the demand time using the power change per unit time.

Estimated Power = Current Power + ((Voltage Change / Unit Time (minutes)) * Remaining Demand Time (minutes))

4. Adjustable power (U)

It means the power required for the predicted power and the target power to match at the end of the demand time limit.

Regulated power = ((predicted power-target power) / remaining demand time (minutes)) * demand time limit (minutes)

The load control terminal controls the driving of the power usage equipment by using the calculated adjusted power. That is, the load control terminal uses the calculated adjusted power to control the driving of the power usage equipment so that the power used by the customer does not exceed the target power.

In addition, the LED module included in the fourth group may be used in an emergency and may be relatively small compared to the power consumption of the first group, the second group, and the third group.

The SMPS 120 converts the AC current supplied to the LED module included in the first group, the second group, and the third group to a DC current and then converts the AC current into a voltage suitable for the conditions of the LED module. To supply. SMPS (120) is converted to a voltage according to the situation according to whether the output of the fire-fighting receiver receiver is alternating current or direct current to supply voltage to the LED module included in the fourth group to the LED module included in the fourth group Supply the voltage. When power is cut off from the outside, the SMPS 120 includes a battery for driving the SMPS 120. In particular, the SMPS of the present invention includes at least four output terminals.
