Hereinafter, with reference to the accompanying drawings will be described in more detail landscape lighting according to a preferred embodiment of the present invention.

1 is a perspective view showing a landscape lighting according to an embodiment of the present invention, Figure 2 is an exploded perspective view showing the body extracted from the landscape lighting of Figure 1, Figure 3 is an assembled state of the body in the landscape lighting, etc. of FIG. 4 is a block diagram illustrating a control system such as landscape lighting of FIG. 1.

1 to 4, the landscape lighting 10 according to the present invention includes a support 20, a support member 30, a main body 40, a light source unit 44, a sensor unit 51, and a driving unit 52. And a control unit 53.

The support 20 and the support member 30 are applied to install the main body 40 spaced apart from the ground by a certain height.

The support 20 and the support member 30 may have various heights and shapes in consideration of the surrounding environment and the characteristics of the object to be illuminated. In addition, in FIG. 1, the support 20 and the support member 30 are illustrated to be installed at a predetermined distance from a roadside or a park, and the main body 40 is coupled thereto, but is not limited thereto. The support 20 and the support member 30 may be omitted. In this case, the main body may be installed to be exposed to the ground, or may be applied to a structure different from that shown to be buried in the ground.

The main body 40 is provided with the case 41 in which the opening part 41b for irradiating light was formed, and the cover 42 which shields the opening part 41b of the case 41. As shown in FIG.

The case 41 has a coupling portion 41a that is coupled to the end of the support member 30, and the light source portion 44 is mounted in the space in the opening 41b.

The cover 42 is coupled to the case 41 to shield the opening 41b, and has a function of transmitting the light emitted from the light source unit 44 to illuminate it. Here, the inner surface of the cover 42 is provided with a diffusion layer 43 surface-treated in a concave-convex shape in order to uniformly diffuse the incident light.

The light source unit 44 includes a heat radiating member 44a, a circuit board 44c, and a light emitting diode 44d.

The heat dissipation member 44a is fixedly installed on the inner surface of the case 41 and applied to emit heat generated by the light emitting diodes 44d and transmitted through the circuit board 44c. Is formed.

The heat dissipation member 44a is preferably connected to the common terminal on the circuit board 44c.

A plurality of light emitting diodes 44d are provided on the circuit board 44c. The light emitting diodes 44d may apply light of different colors. For example, a plurality of red, green, and blue light emitting diodes 44d for emitting red, green, and blue light, respectively, are applied.

The sensor unit 51 is installed outside the support 20 and detects at least one environmental information of temperature, humidity, and wind speed from the surrounding environment and provides it to the controller 53. Preferably, the sensor unit 51 includes a temperature detection sensor 51a for detecting temperature from the surrounding environment, a humidity detection sensor 51b for detecting humidity, and a wind speed detection sensor 51c for detecting wind speed. In addition, the sensor unit 51 has been illustrated in the structure to be installed in the support so as to detect the environmental information on the temperature, humidity, and wind speed from the surrounding environment, it can be installed in places other than the support 20, of course.

When the wind detection sensor 51c applies a structure in which the propeller 51e is rotated in response to the wind speed as shown, the generator is installed on the rotation amount or the rotation shaft of the rotation shaft of the propeller 51e, and the electromotive force generated by the generator It is possible to apply the method of measuring wind speed by detecting. In addition, the wind detection sensor 51c has a wind pressure type anemometer which measures and detects the pressure of the wind, or when the wind hits a heated object, the object is cooled. At this time, the wind turbine is obtained by measuring the degree of cooling. Wind speed can be detected.

The driver 52 selectively drives the light emitting diodes 44d of the light source unit 44 and adjusts the brightness of the selected light emitting diodes 44d. Here, as a method for adjusting the brightness of the light emitting diodes 44d, it is preferable to adjust the brightness of the light emitting diodes 44d by changing a value of an applied current. As another example of the brightness control method, a method of controlling the brightness by adjusting the number of lighting of the light emitting diodes 44d of the same color may be applied.

The controller 53 compares the environmental information detected from the temperature, humidity, and wind speed provided by the sensor unit 51 with a comparison reference value, and adjusts the color or luminance of the light irradiated from the light source unit 44 according to the comparison result. The drive unit 52 is controlled.

An example of a control process of the controller 53 will be described with reference to FIG. 5. First, temperature, humidity, and wind speed are detected (step 110).

Next, the current temperature T value detected by the temperature detection sensor 51a is compared with the first comparison reference T _R value to be compared (step 120).

If it is determined in step 120 that the current temperature T detected by the temperature detection sensor 51a is equal to or greater than the set first comparison reference value T _R , the driving unit 52 is controlled to irradiate light of the color of the first color mode. (Step 130).

Alternatively, if it is determined in step 120 that the temperature value detected by the temperature detection sensor 51a is lower than the set first comparison reference value T _R , light of the color of the second color mode which is different from the color of the first color mode is irradiated. The drive unit 52 is controlled (step 140).

Here, the display color corresponding to the first color mode and the second color mode can be applied by various methods. For example, a temperature at which temperature starts to feel hot is set as the first comparative reference value T _R , and the first color is used. The mode may be set to a mode that emits a cool or cool color, for example blue, and the second color mode may be set to a mode that emits a warm color, for example yellow.

Therefore, when the first comparative reference value (T _R ) is set at 25 ° C., in summer when the temperature is maintained at 25 degrees or more at night, the uncomfortable feeling caused by heat is provided by providing a cool feeling to the viewer looking at the landscape by the blue color emitted. Can be mitigated. Similarly, in winter, when the temperature is lower than 25 degrees set as the first reference value (T _R ) at night, the mind and body shrugged by the cold by irradiating yellow corresponding to the second color mode to give the viewer a warm feeling It can act to relax.

Next, the current humidity M value detected by the humidity detection sensor 51b is compared with the second comparison reference value M _{B to} be compared (step 150).

If the current humidity M value detected by the humidity detection sensor 51b in step 150 is equal to or greater than the set second comparison reference value M _R , the driving unit 52 is irradiated with light in the first brightness mode with respect to the current display color. Control (step 160).

Alternatively, when the humidity value output from the humidity detection sensor 51b is lower than the set second comparison reference value M _R in step 150, the light is emitted in the second brightness mode in which the luminance is lower than the first brightness mode for the current display color. The drive unit 52 is controlled to be irradiated (step 170).

Here, the second comparison reference value M _R is preferably set to a humidity value at which discomfort may be felt. As an example, the second comparison reference value M _R may be set to 40% relative humidity.

In addition, the second brightness mode is set to a suitable brightness that can visually recognize the landscape when looking at the landscape in a psychological state of stability, the first brightness mode is higher brightness than the first brightness mode, but visual Set it appropriately to give a bright and bright feeling.

Therefore, when it is determined in step 150 that the current humidity M is equal to or greater than the second comparison reference value M _R , the light having the luminance corresponding to the first brightness mode that is set brighter than the second brightness mode for the display color determined in step 120. Investigating this can contribute to relieving the discomfort caused by high humidity by visually recognizing the brighter feeling of the landscape. On the other hand, if it is determined in step 150 that the current humidity M is lower than the second comparison reference value M _R , it is determined that there is no discomfort caused by the humidity and the second brightness mode is maintained to suppress unnecessary power consumption.

Finally, the wind speed W output from the wind speed detection sensor 51c is compared with the third comparison reference value W _R as the comparison target (step 180).

In step 180, if the wind speed W output from the wind speed detection sensor 51c is equal to or greater than the set third comparison reference value W _R , the driving unit 52 is added to increase the brightness by the level of the brightness addition mode set for the current brightness. Control (step 190).

Unlike this, when the wind speed W detected by the wind speed detection sensor 51c is lower than the set third comparison reference value W _R in step 180, the driving unit 76 is controlled to maintain the current display color and the current brightness mode. (Step 200).

Here, the third comparison reference value W _R may be set based on, for example, 8.0 m / sec to a degree that allows a psychological feeling.

In this case, when it is determined in step 180 that the current wind speed W is equal to or greater than the third comparison reference value W _R , the landscape is irradiated by irradiating light with brightness corresponding to the brightness addition mode set to the brightness added more than the current brightness. By providing a brighter feeling for the wind can be resolved by looking at the landscape the windy sound. Of course, when the wind speed is lower than the third comparison reference value, the landscape is illuminated by irradiating light having the luminance of the current brightness mode.

On the other hand, the above description has been described to detect all the temperature, humidity and wind speed and to change the color for the temperature, and to change the brightness more brightly if the humidity and wind speed is higher than the set reference value, but in the case of temperature from 18 to 18 It can be constructed to change colors in multiple stages, such as yellow to degrees, green to 19 to 24 degrees, and blue to 25 degrees or more.

In addition, even in the case of humidity and wind speed can be applied to vary the brightness in multiple stages, it can be constructed that can also be configured to change the color according to the humidity value and the wind speed value.

Although the present invention has been described with reference to the embodiments illustrated in the drawings, these are merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments thereof are possible.

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.

As described above, according to the landscape lighting according to the present invention, the psychological of the people looking at the landscape of the irradiation target by selectively adjusting and irradiating the color and luminance of the irradiated light according to the change of the surrounding environment with respect to temperature, humidity and wind speed It can lead to a sense of stability.
