Of course, the circuit board 16 is provided with a main controller 26 for controlling the lamp 14 to be turned on by a sensor signal transmitted from the illuminance sensor 20 or the motion sensor 22.

Therefore, when the ambient light is detected by the illuminance sensor 20, the signal for this is transmitted to the main controller 26 to light the lamp 14. In addition, as in the morning, when the surroundings are dark and bright, the lamp 14 is turned off.

Similarly, when the motion detection sensor 22 detects a user's movement around, a signal for this is transmitted to the main controller 26 to control the lamp 14 to be turned on.

The luminaire case 12 is formed in the shape of a cylindrical body open toward the outer support panel 10, and is formed to protect the circuit board 16 from the outside.

Of course, one side of the luminaire case 12 is formed with a terminal through-hole 121 for connection with a connection terminal formed in the circuit board 16, so that the power required for the operation of the sensor embedded lamp A is supplied. Of course, the circuit board 16 through the terminal hole 121 may further include a signal terminal (not shown) for inputting and outputting signals to the outside, and controlling the operation of the main controller 26 by such a signal terminal. It may be. That is, the lamp 14 is controlled to be turned on by the brightness value input from the sensor of illuminance sensor 20, but the setting value of the lamp 14 start-up brightness value may be changed through a signal terminal by an external computer or a terminal. It is. Therefore, if the brightness value of the incident environment is basically different according to the installation environment of the sensor embedded light (A), it can be configured to be set to the appropriate brightness value to achieve the optimum operating conditions according to the installation environment. It is.

The support member 18 may include a metal support piece 181 supported on an inner surface of a ceiling or a wall and an elastic member having a coil spring shape such that the metal support piece 181 is elastically supported by the luminaire case 12. 182, the metal support piece 181 of the support member 18 is provided to be in contact with the ceiling 30 or the inner surface of the wall as shown in FIG.

In addition, the outer support panel 10 may be formed with a lamp through hole 112 for the light of the lamp 14 to the outer circumference of the sensor through hole 110 for the sensor operation, as shown in FIG. Since a plurality of lamps 14 may be formed, a plurality of lamp holes 112 may also be formed in the external support panel 10. That is, FIG. 2 illustrates that four lamps 14 and four lamp holes 112 are formed.

And the outer circumference of the sensor through-hole 110 is formed with a blocking wall 113 is provided so that the light of the lamp 14 does not flow into the sensor through (110).

That is, the outer support panel 10 is generally formed in a disk shape as shown in FIGS. 1 and 2, and a sensor through-hole 110 is formed in the center thereof, and a luminaire case ( 12) It can be seen that the circular peripheral groove 114 is formed in the lateral direction.

In addition, a plurality of lamp holes 112 are formed at the bottom of the peripheral groove 114, and the tip end portion of the blocking wall 113 by the sensor hole 110 is formed to be positioned at the leading edge of the peripheral groove 114. Therefore, the light of the lamp 14 that is projected through the lamp hole 112 is not incident to the illumination sensor 20 and the motion sensor 22 by the blocking wall 113. This may cause a malfunction when the light by the lamp 14 is incident on the illumination sensor 20 or the motion sensor 22, but the sensor embedded lamp (A) according to the present invention is configured so that there is no such concern This has the advantage of ensuring normal operation at all times.

Furthermore, as shown in FIGS. 1 and 2, a disc-shaped floodlight panel 23 having a central groove 231 is coupled to an outer side of the outer support panel 10 so that the light of the lamp 14 is reflected. A sensor panel 24 for operating a sensor is provided between the central groove 231 of the floodlight panel 23 and the external support panel 10.

This is configured such that the light by the lamp 14 is not only emitted to the outside through the light-transmitting panel 23 and is not incident to the sensors. In addition, the illumination sensor 20 and the motion detection sensors 22 are also configured to be sensed only through the sensor panel 24, so that they are configured to operate stably regardless of the operation of the lamp 14. Of course, the light transmitting panel 23 and the sensor panel 24 may be integrally formed. In this case, after the light of the lamp 14 is incident on the light transmitting panel 23, the sensor may be reflected by the reflection inside the light transmitting panel 23. In order to prevent the incident light toward the illuminance sensor 20 or the motion sensor 22 through the through-hole 110, an opaque boundary member may be inserted at a position corresponding to the sensor panel 24.

Such a sensor embedded light (A) according to the present invention is mainly installed on the ceiling 30 or the wall, it can be installed in various places, such as a corridor, indoors, toilets.

Thus, when installed in the corridor or the like, when the user passes, it may be provided to detect the movement of the rider to turn on and adjust the power to be turned on according to the ambient illumination.

That is, the sensor 14 senses the external illuminance and the motion sensor 22 senses the external movement, and the lamp 14 is turned on or off under the control of the main controller 26. .

According to the degree of the external brightness sensed by the illuminance sensor 20, the main controller 26 adjusts the intensity of the light emitted from the lamp 14 according to the external brightness input. In general, the sun rises in the morning and the sun can be provided to turn on and off in the evening. For example, the external brightness sensed by the illuminance sensor may be provided to be turned off and turned on at about 5 to 30 lux in an environment that depends on sunlight. In addition, where the street lamp is installed, it can be set to turn on and off in the illumination of the external environment of a brighter degree than this. This is because the external illuminance of a certain brightness is sensed even in the dark night by the street light, the setting value for the external illumination of this degree is provided to be set at the time of installation according to the environment in which the sensor embedded light (A) according to the present invention is installed. This is preferred.

As such, the lamp 14 may be provided to be turned on and off according to the external illumination environment, and the lamp 14 may be provided by subdividing the detected brightness of the external illumination environment such as a cloudy day. Accordingly, the main controller 26 may be provided to determine the brightness of the outside detected by the illumination sensor 20 as bright brightness, medium brightness, or dark brightness. Of course, the light, medium and dark degree is preferably provided to be set at the time of installation on the basis of the maximum brightness at the installation site.

As an example, where the sunlight is shining, the bright brightness may be set to 50 lux or more, and the medium and dark brightness may be set to about 5 to 15 lux. However, depending on the installation environment, it may be set such that bright brightness is set at 30 lux, dark and medium brightness between 5-10 lux in short passages or in general buildings where sunlight is not directly reflected. It may be provided to be adjusted appropriately.

As described above, the main controller 26 controls the lamp 14 to be turned on and off according to the brightness of the outside sensed by the illumination sensor 20. In the morning when the bright state is changed from a dark state to a bright state, the lamp 14 may be turned off, and when the sun goes down, the lamp 14 may be provided to light up.

In addition, the main controller 26 may be provided so that the lamp 14 is turned on by a signal detected from the motion detection sensor 22. After detecting the movement of a person, the lamp 14 is turned on. In addition, the brightness of the lamp 14 may be provided to be turned off while gradually darkening. As an example of gradually being turned off, after 1 to 5 seconds after the first light, the power of 1/3 of the power is reduced to be turned on, and after 5 to 15 seconds 2/3 of the power of the first light is reduced again The lamp 14 may be turned off after 5 to 15 seconds.

Therefore, the user who feels the surrounding environment gradually darkens to move again to detect the motion sensor 22, to prevent sudden darkening.

Looking at a series of lighting control sequence for the operation of the sensor embedded light (A) according to the present invention is provided as follows.

That is, first, when the motion detection sensor 22 detects the user's movement, the motion detection step of transmitting the detection signal to the main controller 26 is performed.

Thereafter, the main controller 26 receives an ambient brightness value detected by the illuminance sensor 20, and then performs an illuminance detecting step of determining whether it is dark.

Thus, if the ambient brightness is bright, even if the motion sensor 22 detects the movement of the surroundings, the lamp 14 does not operate so as to light up.

However, when it is determined that the surroundings are dark, the lamp lighting step is performed to supply power so that the lamp 14 is turned on so that bright light is emitted from the lamp 14.

As described above, in the state in which the lamp 14 is turned on, a lamp extinction step is performed in the main controller 26 to turn off the lamp 14 after a predetermined time has elapsed.

In such a lamp turning off step, the lamp 14 may be controlled to turn off after a predetermined time of about 30 seconds to about 5 minutes, but more preferably, the lamp 14 may be controlled to become dark gradually. That is, for a certain period of time to turn off the light of about 30 seconds to 10 minutes, it is to be divided into three, so that the power is supplied to the initial brightness for the first 1/3 hour, and then the initial brightness for 1/3 to 2/3 time. The power will be supplied so that the brightness is 2/3 of the power of. And for 2/3 to 3/3 hours, the power will be supplied to be 1/3 of the brightness of the initial brightness. Of course, after 3/3 hours have passed, the lamp 14 is controlled to turn off.

As such, after the lamp 14 is controlled to turn off, a signal input waiting step is performed to wait for a signal input of the motion detection sensor 22 that detects the next user's movement.

The embodiments of the present invention have been described in detail above, but since the embodiments have been described so that those skilled in the art to which the present invention pertains can easily carry out the present invention, The technical spirit of the present invention should not be interpreted limitedly.
