1 is a block diagram schematically showing a power saving multifunction luminaire according to the present invention, Figure 2 is a plan view showing a power saving multifunction luminaire according to the present invention.

First of all, prior to a full description, the power-saving multifunctional luminaire according to the present invention will be described as follows.

Energy-saving multi-functional luminaire according to the present invention is installed in any place where the lighting is required to illuminate the required number of LEDs according to the motion of the human body detected in the use space provided with the illumination to the body temperature and ambient brightness, suitable for the external environment of the use space. to provide. In other words, if a person's movement or body temperature is not detected even after a predetermined time, or if the brightness of the used space is enough to operate without additional lighting, unnecessary lighting is automatically turned off to prevent waste of energy. do. At this time, the off is not one-sided ON / OFF, but by adjusting the number of LED off to distinguish according to the surrounding conditions in some cases can provide the user with the required brightness of the brightness to the use space to solve the inconvenience.

In addition, the power is charged separately during phase change, and the power is turned on so that the user temporarily understands the surrounding objects by using the charging power or lights up an arrow-shaped guide light that leads to the entrance and exit so that the user does not panic. The watch is always displayed, including in case of power failure, to provide time information to the user.

In addition, when used for the lighting of the library or students stand, it is possible to efficiently manage the study time by turning on only a predetermined time through a timer.

To this end, the energy-saving multi-functional luminaire according to the present invention has a power supply unit 110, a setting unit 120, a sensing unit 130 for detecting an external condition, an LED 140 and a lighting unit 140 flashing as shown in the charging unit. ), A time display unit 150 for displaying time information, and a controller 160 for adjusting brightness and blinking of the lighting unit 140.

Looking at each in detail with the accompanying drawings as follows.

Figure 3 is a block diagram showing a sensing unit 130 of the power-saving multi-function luminaire according to the invention, Figure 4 is a cross-sectional view showing the lighting unit 140 of the power-saving multifunction luminaire according to the invention, Figure 5 is a power-saving type according to the present invention 4 is a plan view illustrating a time display unit 150 of yet another embodiment of a multifunctional lamp.

First, the power supply unit 110 provides a direct current or alternating current, and in the case of providing direct current, generally includes a circuit for converting electricity of alternating current supplied to a home or a factory into direct current. Such a circuit may use a conventional AC / DC converter circuit. On the other hand, in the case of providing the alternating current, the LED elements can be arranged in both directions and turned on according to the sinusoidal characteristics of the alternating current.

The configuration of a power source for blinking the LED using such an AC or DC power source uses a conventional circuit, which is obvious to the application and understanding of those skilled in the art.

Next, the setting unit 120 may be provided with an operation button (not shown) to set a reference value with respect to time, motion, and illuminance.

For example, in the case of the time, the current time and the ON / OFF time can be set to blink at a desired time. At this time, the timer 121 may be further provided to set the lighting time with the timer 121 so that the lighting is performed for a predetermined time.

The movement is related to the presence or absence of a person's activity in the use space, and is a setting regarding a time range in which a person's motion or body temperature is not detected, that is, a dead time.

This floating time increases the range of floating time (time when no movement is detected) in the place where user's movement is not active, such as the library, and shortens the range of floating time in the place where user's movement is relatively active. If the motion or body temperature is not detected for more than the corresponding time, the time range may be set to determine that no lighting is required at the corresponding place.

Further, the floating time is a first floating time for distinguishing that there is no user in the used space because there is no movement for the first predetermined time, and then a second floating for distinguishing that an off is expected when a predetermined time further elapses from the first floating time. The time may be set to be differentially set to the third floating time which distinguishes that the predetermined time is further turned off after the second floating time. As described above, when the motion is not detected during the differential dead time, the plurality of LEDs 142 may be differentially turned off by the controller 160 to form a separate illumination as described below.

In the case of the illuminance, the reference illuminance may be set in response to how dark the surroundings are blinking so that when the ambient brightness is brighter or darker than the reference illuminance by natural light, the illuminance may be reacted accordingly.

In addition, the setting unit 120 allows the user to set the quantity of light emitted from the plurality of LEDs so that only the designated quantity is turned on.

Next, the detector 130 includes a human body detector 131, an illuminance detector 133, and a power failure detector 135 as shown in FIG. 3.

The human body detecting unit 131 detects body movement or body temperature of the human body. That is, the user's movement to the body temperature in the use space is detected, the illuminance sensor 133 detects the brightness of the surroundings, the power failure detector 135 is supplied to the power supply 110 (see FIG. 1) Detect power failure.

For this purpose, the sensor provided in each sensing unit is conventional and its use is obvious to those skilled in the art.

Next, as shown in FIG. 4, the diffusion unit 143, the correction member 145, and the illumination window 147 are sequentially disposed on the PCB 141 to which the plurality of LEDs 142 are fixed as shown in FIG. 4.

The plurality of LEDs 142 are mounted on the PCB 141.

Therefore, the energy-saving multi-functional luminaire according to the present invention has a semi-permanent life due to the use of LEDs, and is about 50 times less heat than the conventional fluorescent lamps (heating of the ballast operated when using fluorescent lamps causes a risk of fire). Safety can be achieved, installation is easy in any place, location, etc. with simple circuit configuration, and the durability of LED material itself made of epoxy molding is very easy to handle. In particular, the low power effect of the LED material itself can save power consumption.

The plurality of LEDs 142 mounted in this way are arranged at regular intervals, and in some cases, all of the lights are turned on or only the LEDs 142 of a predetermined area are turned on to illuminate the lights so as to be distinguished, such as all lighting, division lighting, and lighting at the arrow. Is achieved.

The diffusion member 143 is provided as an aggregate of lenses 144 corresponding to each LED 142 and is disposed above the PCB 141. As a result, the point light source emitted from the LED 142 may diffuse and spread to the point light source having a wider cross-sectional area.

The correction member 145 is disposed above the diffusion member 143, and the upper surface is flat and the lower surface facing the diffusion member 143 is provided as a triangular embossing surface 146, so that the light of the point light source drawn from the diffusion member 143 is provided. Is emitted by the light of the surface light source.

In this way, the light of the LED processed through the diffusion member 143 and the correction member 145 is suitable to illuminate the large area of the light brightly and the straight light is removed to prevent the glare of the user.

The lighting window 147 may add a pattern or color as necessary to more beautifully express the LED light emitted.

Next, the time display unit 150 is displayed to the outside as shown in FIG. 2 or 5.

In the case of FIG. 2, the hour display unit 151 and the minute display unit 153 are provided separately, and the hour display unit 151 is lit by one LED every hour, and the minute display unit 153 is It can be shown that one LED turns on every five minutes.

Alternatively, as shown in FIG. 5, the number may be directly displayed on the digital display window 155 to provide time information.

Next, the controller 160 determines the brightness of the illumination to be provided by using the reference value set by the setting unit 120 and the sensing information of the detector 130 and the lighting unit according to the determination. And an output unit 163 for separately outputting the lighting brightness of the 140.

Looking at each of the determination cases and the lighting of the division associated with each of the determination case that is illuminated by the determination unit 161 and the output unit 163 as described above are as follows.

The determination unit 161 determines as follows.

If the user's motion or body temperature is not detected by the human body sensor 131 for more than a preset dead time, it is determined that normal lighting, which is the maximum brightness displayed by the corresponding luminaire, is unnecessary because the user does not exist in the corresponding space. In this case, if the dead time is differentially set to 1, 2, and 3 orders as described above, when the time without the detection of motion is within the range of the 1 st dead time, '1/2 illumination is unnecessary', the 2 nd float In the case of the time range, it is judged to be different, such as '3/4 lighting is unnecessary', and in the case of the third dead time, 'all the lighting is unnecessary'.

In addition, when the ambient illuminance is detected by the illuminance detecting unit 133 below a predetermined reference illuminance, the additional space of the lighting unit 140 may not be satisfied because the use space does not satisfy the reference illuminance set by the user only by natural light. I think it is necessary.

In addition, when the external power is cut off by the power failure detection unit 135, it is determined that emergency lighting is necessary as the power failure.

Based on the determination, the output unit 163 is lighted as follows. The lighting at this time is based on the premise that additional illumination is required according to the detection of ambient illuminance below the reference illuminance. In other words, when the ambient light is detected above the standard light, natural light alone is sufficient to provide additional illumination.

1) All lights up: All LEDs 142 emit light, and it is determined that there is a user whose motion is sensed in the used space because the timer 121 is not set or the time in the setting has not elapsed. That is, normally all of the plurality of LEDs 142 are lit to provide maximum brightness.

2) Completely extinguished: All the LEDs 142 and the digital display 155 of the lighting unit 140 and the time display unit 150 are extinguished and the user's movement is not detected in the third dead time range. It is a case where it is determined that lighting is unnecessary.

3) 1/2 lit: Only half of the total number of LEDs 142 is lit.The timer 121 is not set or the time within the set has not elapsed and the user's movement has not been detected and should be turned off. This is a case where it is determined that '1/2 illumination is not necessary', which is not completely turned off in the first dead time range. In other words, the illuminance is somewhat lowered, but by constantly illuminating the use space, the user can recognize the object in the use space and wait for normal lighting at any time in close proximity to the user.

4) 1/4 lit: Only the minimum of the total quantity of the LED 142 is emitted, and should be turned off because the time set in the timer 121 has elapsed or the user's movement is not detected. This is the case where it is determined that '3/4 illumination is not necessary' or not when completely turned off in the second dead time range, or when the power failure occurs. In other words, minimal illumination is provided so that the user can perceive the dark space.

5) On when the arrow: Among the LEDs 142, the LEDs forming the shape of the arrow emit light, and when the emergency light is determined to be necessary, the user's movement regarding the dead time is not determined. In other words, the location of the emergency exit or firefighting can be identified by the guidance.

6) Light up the designated quantity: When the user sets a certain quantity of lighting through the setting unit 120, it is lit accordingly. In this case, the output unit 163 may adjust lighting according to the case of 2) to 5).

In addition to the above, in all cases 1) to 5), the time display unit 150 may be displayed by being turned on, but may be turned off when completely turned off if necessary.

The energy-saving multi-functional luminaire according to the present invention, which is provided in this way, is installed in all places where lighting is required, and according to the movement, body temperature, and illuminance of the human body, the lighting is turned on or off to prevent unnecessary waste of energy and the charging unit 111 during power failure. By using the standby power of the emergency response to provide a light or an arrow to guide the emergency exit side.

Therefore, all LEDs 142 are turned on to provide maximum illumination in the used space, but when the user does not have movement or body temperature, that is, when unnecessary lighting is being provided, the lamp is automatically turned off, and in some cases, differential lighting is provided. Therefore, unlike power saving while giving inconvenience to activities by unilateral ON / OFF, the user does not feel inconvenience by providing necessary lighting for each category.

In addition, by using the standby power in the case of power failure, the necessary light to the arrow to emit light when the user can cope with calmness without being embarrassed, as well as the time is displayed to provide better convenience to the user.

Hereinafter, with reference to the accompanying drawings the operation and use of the power-saving multi-function luminaire according to the present invention.

Figure 6 is a plan view showing the division lighting of the power-saving multi-functional luminaire according to the invention, Figure 7 is a plan view showing the lighting of the arrow of the power-saving multifunction luminaire according to the invention.

The present invention can be a place where people frequently leave the space after leaving for a short time, such as apartment-type factories and offices, and may be a slight savings individually, but collectively can see the effect of large power saving as a whole It can be used in buildings such as factories, dormitories, and academies. In addition, places where man-made lighting is essential, such as dangerous places and enclosed places, and have a large number of people at the same time, emergency exits (emergency stairs, emergency exits, fire-intensive cooking rooms) belonging to fire-fighting equipment, and fire extinguishers (fire extinguishers) Location guidance guidance).

Thus, the power-saving multi-functional luminaire according to the present invention installed in various places is used as follows.

First, when there is a user's activity continuously in the use space and the natural light of the surroundings alone does not satisfy the preset standard illuminance, the power-saving multifunctional luminaire according to the present invention is normally turned on. In this case, all the LEDs 142 of the lighting unit 140 are turned on to provide illumination of maximum brightness.

If the user's movement or body temperature is not detected in the first dead time range, which is used as described above, only half of the total quantity of the LEDs 142 is turned on as shown in FIG. Provide illumination with illumination.

Therefore, the user is not inconvenient to identify the object in the space and when the user's movement is detected again, the illumination of the maximum brightness is provided so that there is no inconvenience in the user's activity.

However, as shown in FIG. 6, when only half of the total quantity of the LEDs 142 is lit, but the user's motion or body temperature is not detected until the second dead time range, the number of lightings is turned to 1/4 of the total quantity of the LEDs 142. It is reduced to provide only minimal illumination to the space used.

Then, when there is no detection of the user's motion or body temperature to the third dead time range, all LEDs 142 are turned off.

In addition to the above process, the time display unit 150 always emits light to the outside, and when the external conditions persist such that no additional time is displayed, the time display unit 150 is turned off to achieve maximum power saving.

Next, in the case of power failure, the power failure detector 135 detects a power failure from the outside and when the ambient illuminance is darker than the standard illuminance, the output unit 163 receives the standby power from the charging unit 111 to receive the lighting unit 140. As shown in FIG. 7, the plurality of LEDs 142 are turned on to display an arrow shape. At this time, the time setting of the timer 121 and the presence or absence of user movement are not considered.

When the arrow is lit in this way, the lighting guides the emergency exit or fire fighting equipment.

In addition, when the user sets the lighting time through the timer 121, all the LED 142 is turned on by the corresponding time, and when the user arbitrarily determined the quantity of lighting through the setting unit 120 accordingly the output unit 163 ) Lights up a predetermined number of LEDs 142 evenly distributed on the lighting unit 140. At this time, according to the setting of the timer 121, depending on the presence or absence of the user, according to the detection of the ambient illuminance, the light is turned on or off.

The above description is only a preferred embodiment of the present invention, and there may be various modifications. However, if these modifications are included in the technical spirit of the present invention will be within the scope of the present invention, the scope of the present invention can be easily understood by those skilled in the art through the following claims.
