The intelligent module unit 130 is configured to receive light according to the change of the time and the surrounding environment The intelligent LED lighting apparatus according to the present invention is a component for controlling the divergence of light by the light source dispensing unit 100. By combining the light source dispatching unit 100 and the intelligent module unit 130, It is possible to operate automatically without energy saving and to maximize lighting effect.

1, the light source emitting unit 100 of the intelligent LED lighting apparatus according to the present invention includes one or more LEDs (Light Emitting Diodes) 110 that are supplied with power and emit light .

The LED 110 is composed of a compound such as gallium arsenide and emits light when an electric current flows. The LED 110 may be any one of known LEDs. The LED 110 is controlled by the intelligent module 130, And diverts the light in the daytime, but also emits light in the daytime according to weather conditions.

That is, the LED 110 emits light when the periphery of the intelligent LED lighting apparatus is in a dark state, and ceases divergence of light when it is in a bright state.

1 and 2, the light source dispensing unit 100 of the intelligent LED lighting apparatus according to the present invention includes an incident surface on which light emitted from the LED 110 is incident, And a light guide plate (120) having a pattern surface (121) on which patterns are formed.

The light guide plate 120 is a transparent acrylic panel that converts a point light source such as the LED 110 into a surface light source. As shown in FIG. 2, the pattern surface 121 formed on the light guide plate 120 And a plurality of U-shaped grooves 122 formed regularly.

In one preferred embodiment of the present invention, the pattern surface 121 may have a length of 100 mm to 1 m, a width of 10 mm, and a plurality of U Each of the groove-shaped grooves 122 may be formed to have a length of 8 mm, a width of 1 mm, a depth of 500 μm, and each corner portion may be C-cut.

The width of the U-shaped groove 122 corresponds to the length of the pattern surface 121 and the length of the U-shaped groove 122 corresponds to the width of the pattern surface 121.

2, the interval between the plurality of U-shaped grooves 122 may be regularly formed by applying the Fibonacci formula.

That is, the Fibonacci sequence f (n) = 1 (n <= 2); the interval between the first U-shaped groove closest to the incident surface side and the next second U-shaped groove according to f (n) = f (n-2) + f (n-1) The distance between the second U-shaped groove and the third U-shaped groove is 2 mm, the distance between the third U-shaped groove and the fourth U-shaped groove is 3 mm, and the fourth U- And the interval between the fifth grooves and the fifth U-shaped grooves may be 5 mm.

In this case, the Fibonacci sequence has the first and second appearances of 1, and the first one is the interval between the incident plane and the first U-shaped groove.

Also, the Fibonacci sequence f (n) = 1 (n < = 2); the first U-shaped groove closest to the incident surface side and the second U-shaped groove closest to the incident surface side are divided by 2 according to f (n) = f (n-2) + f (n-1) Shaped grooves is 0.5 mm, the distance between the second U-shaped grooves and the third U-shaped grooves is 1 mm, the distance between the third U-shaped grooves and the fourth U-shaped grooves is 1.5 mm And the distance between the fourth U-shaped groove and the fifth U-shaped groove may be 2.5 mm.

With this configuration, when the length of the pattern surface 121 is 100 mm, the number of U-shaped grooves 122 formed on the pattern surface 121 is ten, and the length of the pattern surface 121 It is obvious that the number of U-shaped grooves 122 that can be formed varies.

The intelligent LED lighting apparatus according to the present invention is characterized in that the light incident on the light guide plate 120 is incident on the pattern surface 121 by the standard of the U-shaped groove 122 and the interval between the U- It is possible to suppress the diffuse reflection to suppress the white spot phenomenon caused by excessive superimposition of light, suppress the formation of the dark portion in the light guide plate 120, and maximize the light efficiency.

1, the intelligent module unit 130 of the intelligent LED lighting apparatus according to the present invention includes an intelligent control module 140 for controlling the light emission of the LED 110 .

The intelligent control module 140 is an element for automatically controlling the light emission and brightness of the LED 110 according to the change of the time and the surrounding environment. As shown in FIG. 3, the intelligent control module 140 includes date and time information And an arithmetic processing unit (142) for controlling the light emission of the LED (110) based on the algorithm data, the data base (141) being composed of a plurality of numeric data .

Wherein the algorithm data is data including leap year data composed of normal data composed of numeric data of 1 to 31,536,000 and numeric data of 1 to 31,622,400, and each numerical value constituting the leap year data and the leap year data The data includes date and time information, solar information on perception after sunrise and post-sunrise, and is used as an application for controlling the LED 110 according to the passage of time.

That is, numerical data of 1 to 31,536,000 and numerical data of 1 to 31,622,400 are data that is activated after being activated one by one in each second of the time flow composed of hour, minute and second, and is inactivated after being activated one by one. .

Specifically, the 365 days corresponding to one year is 8,760 hours, the minute corresponds to 525,600 minutes, and the second corresponds to 31,536,000 seconds, so that the numeric data from 1 to 31,536,000 may include date and time information And sunrise and sunset times of each date can be estimated based on various data such as seasons and statistical data. Thus, each of numerical data from 1 to 31,536,000 has a date and time corresponding to each numerical data at sunrise And solar information about post-cognitive post-sunset awareness.

At this time, since the leap year constituted by 366 days of one year is returned with the period of 4 years, the above-mentioned normal year data is data for use in the normal year which is constituted by 365 days of one year, and the leap year data is constituted by 366 days of 1 year It is obvious that the algorithm data is configured such that the leap year data is processed once after the normal year data is repeated three times.

4, the numerical data corresponding to 5,097,661 of the normal data of the algorithm data represents 12:00 am on March 1, and since it is self-evident in the seasons and the statistical succession after the sunset, The arithmetic processing unit 142 may control the LED 110 to remain off when numeric data corresponding to 5,097,660 of the normal data of the algorithm data is activated.

In another embodiment of the present invention, the numerical data corresponding to 5,097,661 of the leap year data of the algorithm data represents 12: 1 am on Feb. 29, and since the seasons and statistical succession of the sunset are self-evident, May control the LED 110 to remain off when numeric data corresponding to 5,097,660 of normal data of the algorithm data is activated.

The illuminance sensor 160 is a component that senses the ambient illuminance of the intelligent LED lighting apparatus and is a component that operates only after the sunrise and before the sunset by the control of the arithmetic processing unit 142 based on the algorithm data.

That is, when the arithmetic processing unit 142 performs the light emission control of the LED 110 only by the algorithm data, the date and time of the algorithm data may be changed by the intelligent LED lighting apparatus The arithmetic processing unit 142 has a limitation in that the LED 110 can not be turned on even if the periphery of the LED 110 is darkened.

In addition, when the operation processing unit 142 performs the light emission control of the LED 110 only by the ambient illuminance sensed by the illuminance sensor 160, if the periphery of the intelligent LED illuminating apparatus becomes dark, The controller 142 turns on the LED 110 so that the LED 110 is immediately turned off when the illumination sensor 160 senses the light emitted by the LED 110 or the surrounding signboard, It is necessary to pay attention to the arrangement of the illuminance sensor 160 and to maintain the illuminance sensor 160 at all times. As a result, the power consumption is excessively required.

Therefore, in order to prepare for the situation that the periphery of the intelligent LED lighting apparatus becomes dark due to the state before the sunset or the weather condition after sunrise on the date and time of the algorithm data, the operation processing unit 142 basically sets the algorithm data as a base And controls the LED 110 in accordance with the date and time of the algorithm data. However, if the illuminance detected by the illuminance sensor 160 is less than a preset reference value The LED 110 is turned on.

In one embodiment of the present invention, when the numerical data corresponding to the numerical data before sunrise after sunset among the normal data of the algorithm data is inactivated after being activated one by one, the operation processor 142 supplies the numerical data to the illuminance sensor 160 The illuminance sensor 160 may be disabled by a method of shutting off the power.

In addition, in another embodiment of the present invention, when the numerical data corresponding to the normal data of the algorithm data before and after the sunrise are activated one by one and are inactivated, the arithmetic processing unit Power may be supplied so that the illuminance sensor 160 senses the illuminance around the intelligent LED lighting apparatus.

Accordingly, the operation processing unit 142 may be provided with a reference illuminance that can be arbitrarily set by a user or the like, and the arithmetic processing unit 142 may be configured such that the illuminance around the intelligent LED illuminating apparatus, which is detected by the illuminance sensor 160, , It is possible to control the LED 110 which is in an unlit state to be turned on.

At this time, the arithmetic processing unit 142 can not necessarily input only one reference illuminance, but may be configured to input a plurality of different reference illuminances.

When the reference illuminance is input to the arithmetic processing unit 142, the illuminance of each reference illuminance is set to a reference value for adjusting the brightness of the LED 110, And the arithmetic processing unit 142 may adjust the brightness of the LED 110 according to illuminance around the intelligent LED lighting apparatus detected by the illuminance sensor 160.
