Description

 Intelligent lighting device

Technical field

 The present invention is an intelligent lighting device, in particular, a design that can adjust the intensity of illumination in response to ambient brightness within a predetermined range, and has both power saving functions and uniform or differentiated ambient brightness. Background technique

 For the existing lamp body, please refer to the power-saving lamp structure of Taiwan Patent Publication No. M418231, which is a power-saving lamp structure, especially one that can save excess current supply of the lamp and can greatly reduce the expenditure of power resources. And waste of innovative structure; the main luminaire is composed of a central processing unit (CPU), a photoresistor, and an infrared human body sensor; with this innovative and unique design, the luminaire of this patent is made up of a photoresistor and an infrared human body sensor. The utility model can save the excess current supply of the lamp, and can greatly reduce the expenditure and waste of the power resource, thereby enabling the patent to achieve the practical progress of the power energy saving. However, although the conventional lamp body can automatically adjust the luminous flux in accordance with whether the ambient light is sufficient or not, the photosensitive light is used to sense the ambient light intensity, but in fact, the photoresistor only feels the difference in ambient light brightness. However, it cannot be properly limited to the intended range of induction. In particular, multiple lamps are usually installed indoors, and only the area where the human activity is active requires a large illumination brightness, or the lamp body near the window has light transmission in the daytime. When it is necessary to reduce the brightness state, or when some of the lamp body is damaged and inadvertently regulated in a low illumination state, other lamp bodies should also be used to illuminate the brightness of the illumination, but the photoresistor Obviously, it can't be judged by maneuverability, but it can't respond to brighter, darker or two-light illumination intersections. When the illumination brightness changes at any time, the effective illumination brightness is strengthened and reduced, which makes it easy to happen:

1. It is not possible to sense the degree of illumination within a given range to adjust the amount of light that the lamp body itself should reinforce and reduce, so that the interior appears to be too noticeably bright.

 2, the light body can not mutually sense the amount of light and thereby strengthen, reduce the amount of light, causing waste of power when excessive lighting, or excessive darkness when the light is insufficient.

3. The amount of illumination in each activity block in the room is not consistent, but each activity block should also have a certain illumination value to maintain the lighting demand. Therefore, if the lamp body between the blocks cannot be used to sense each other and change the light quantity setting, Obviously, it is not possible to adjust the corresponding brightness values of the blocks. In addition, the existing lamp body is mostly powered by solar panels, and the solar panel absorbs sunlight energy accumulation and converts it into electric energy. Therefore, the energy saving degree is affected by the climate, the energy accumulated on cloudy days is limited, and at night, no sunlight can accumulate energy. If the lamp body is not controlled during the cloudy or nighttime illumination, it is easy to make the accumulated capacity of the solar panel quickly exhausted, so that the lamp body emits weak or no light, especially when the solar panel is used in the street lamp, the street lamp is in the electric power. The lack of power must be accompanied by additional power supply from the power plant to illuminate. This is contrary to the intention of natural energy supply and environmental protection. It is obvious that if the solar panel body can not self-regulate brightness according to the change of ambient brightness, it is easy to waste unnecessary accumulation. It is also difficult to achieve the effect of energy saving and carbon saving.

 Since the above-mentioned existing lamp body cannot be reinforced according to the ambient brightness within a predetermined range, the illumination brightness is lowered, the power cannot be saved, or the shortness is easily caused, and the power stored in the solar panel lamp body is limited, if the lamp body cannot self When the brightness is regulated, it is easy to quickly deplete the accumulated electric energy. Therefore, the inventors of the present invention need to improve it, and should design an illumination intensity that can be adjusted according to the ambient brightness within a predetermined range, and also has the function of saving electricity and making the environment A uniform or differentiated lamp body structure. Summary of the invention

The present invention relates to an intelligent lighting device, as shown in FIG. 1 and FIG. 2, which is a main embodiment of the present invention, and includes at least one lamp housing 1 (which can be a table lamp, which can be mounted on an object (indoor wall). a fluorescent lamp or a street lamp, etc., the lamp housing 1 is provided with at least one light emitting unit 2 and at least one light collecting unit 3, wherein: The light-emitting unit 2 is disposed at the lamp housing 1 and can be illuminated to the outside of the lamp housing 1 when the power is received, and the light collecting unit 3 is disposed at the lamp housing 1 , and the light collecting unit 3 faces the lamp housing 1 . As shown in FIG. 1 , the lamp housing 1 is mounted on an indoor ceiling, and the lamp housing 1 is provided with a collecting curved surface 11 , and the lighting unit 2 and the light collecting unit 3 are disposed on the collecting surface. 11 , by the light collecting surface 11 to reflect the light emitted by the light-emitting unit 2 toward the outer direction of the lamp housing 1 and matching the curvature value of the collecting curved surface 3, so that the light is irradiated in a predetermined direction, as shown in this embodiment, The lamp housing 1 is affected by the respective light collecting surfaces 11 which are the intersecting illumination regions of the light-emitting units 2 of at least two lamp housings 1 , and the light collecting unit 3 faces the to-be-detected region 4, and the light collecting unit 3 The direction can be controlled (for example, mechanical automatic or artificial regulation), thereby adjusting the position of the area to be detected 4, for example, the intersecting illumination area of the lamp housing 1 of the embodiment, or the non-intersecting illumination area, and the lamp housings 1 can set a plurality of light collecting units 3, a light collection sheet between the lamp housings 1 The element 3 can be singularly and in combination corresponding to the predetermined to-be-detected area 4;

 The light collecting unit 3 is provided with a micro control unit 33 and a pulse width modulation unit 34 (further including a differential amplifying unit 31 and an analog to digital converting unit 32), as shown in FIG. 2, wherein the differential amplifying unit 31 can sense The ambient light brightness of the detection area 4 is detected, and the sensing information is amplified by the signal and transmitted to the analog-to-digital conversion unit 32 (the differential amplification unit 31 is an existing configuration, and the induction information can be effectively amplified and outputted).

 The analog-to-digital conversion unit 32 (referred to as an Analog-to-digital converter, generally referred to as A/D, is a device for converting a continuous signal in an analog form into a discrete signal in a digital form), and converts the sensing information from analog information to digital The information is transmitted to the micro control unit 33 for operation, and the micro control unit 33 (a type of micro processor, commonly referred to as an MCU) has a preset ambient luminance value to be received by the micro control unit 33 via the received number. After comparing the information with the preset ambient brightness value, the difference of the ambient brightness is calculated, and the difference is transmitted to the pulse width modulation unit 34 by the command information (Pulse Width Modulation, abbreviated as PWM, which converts the analog signal) As a technique of pulse wave, the period of the pulse wave is generally fixed after the conversion, but the duty ratio of the pulse wave changes according to the size of the analog signal), and the added differential amplification unit 31 and the analog-to-digital conversion unit 32 provide more accurate The sensing effect allows the micro control unit 33 to read a more accurate value.

It is worth mentioning that the light collecting unit 3 is provided with a photosensitive semiconductor component, which comprises a differential amplifying unit 31 and a light emitting unit 2, and is an integrated component having light emission, light receiving and light signal amplification; The lamp housing 1 is further provided with an adjusting unit 36 connected to the micro control unit 33, and the adjusting unit 36 can manually adjust the lighting effect of the lighting unit 2, so that the user can follow the preference The brightness of the light-emitting unit 2 or the like is adjusted to provide a more comfortable lighting effect. Thereafter, the pulse width modulation unit 34 regulates the brightness of the corresponding difference between the light-emitting unit 2, and increases or decreases the brightness of the light corresponding to the ambient brightness at the area to be detected 4, so that the composition and function of the light collecting unit 3 are differentiated. The amplifying unit 31 senses and amplifies the intensity of the light to be detected by the area to be detected 4, and the analog-to-digital conversion unit 32 and the micro-control unit 33 transmit and calculate the difference between the brightness of the built-in environment and the ambient brightness of the area to be detected 4, via the pulse width modulation unit. The command light-emitting unit 2 irradiates the detection area 4 with the reinforcement of the corresponding difference or reduces the ambient brightness, so the present invention has the following features:

 1. When the intersecting illumination area corresponding to the embodiment is the area to be detected 4, the light collecting unit 3 of one of the lamp housings 1 can detect the brightness value of the illumination unit 2 of the other lamp housing 1 to be irradiated to the area to be detected 4 According to self-sensing and adjusting the brightness of the light, for example, a single active block requires a certain brightness value, and the light collecting unit 3 between the adjacent plurality of lamp housings 1 may be single or cross corresponding to the area to be detected 4, when some of the lamp housings 1 When the brightness is insufficient, the other lamp housings 1 can equalize or different degrees of complement brightness to the required brightness value of the active block, so that the active block maintains an appropriate and constant illumination brightness.

 2. When it is not corresponding to the state of the embodiment, for example, a light-transmitting area along the window may be the area 4 to be detected, and the light collecting unit 3 leaning into the window light housing 1 may face the area to be detected singly or in combination. The light-emitting unit 2 near the window lamp housing 1 reduces the amount of light, or the amount of light is supplemented when the light is insufficient, and has the advantage of saving illumination power or preventing excessive darkness in response to external light transmission intensity.

3. The indoor activity block can be divided into the main activity area, the secondary activity area and the rarely active area. Although the illumination requirements of the three activity areas are different, but the excessive area of the activity area cannot be connected in the brightness. Otherwise, it is easy to cause a strange sense of the difference in illumination brightness. Therefore, the lamp housing 1 in which the active area is placed against each other should cause the light collecting unit 3 to face each other to the appropriate area 4 to be detected, so that the difference in the amount of illumination in the excessive zone is moderated, and The other zones of the other lamp housings 1 are used to reinforce and reduce the difference between the illuminance and the required values of each zone, so that each zone can meet the required amount of illumination, and the active area is mainly saved by electricity. The area is mainly bright, and the secondary activity area and the main and few active areas are the soft connection of the illuminance. This is the advantage that the existing indoor lamp body can not be achieved by the photoresistor. The present invention can achieve the mobile unit 3 to achieve the mobile sexy The effect of the amount of illumination should be adjusted according to the ambient brightness of the given area. Moreover, when the illumination regions are mutually covered by the plurality of lamp housings 1, the light collecting unit 3 of each of the lamp housings 1 may be directed to the appropriate intersecting illumination region as the to-be-detected region 4, and the micro control unit 33 has a preset or The light collecting unit 3 senses the ambient brightness except for the light of the predetermined brightness emitted by the adjusting light emitting unit 2. Giving the amount of illumination to the area to be detected 4, and calculating the difference between the predetermined brightness value to be emitted by the light-emitting unit 2 and the brightness value projected by the other lamp housing 1 to cause the light-emitting unit 2 to supplement or reduce the illumination corresponding to the difference Therefore, the light collecting unit 3 can be used as the cross-assisted sensing between the lamp housings 1 , and the appropriate light of the corresponding difference is determined according to the ambient brightness and the brightness of the projected light of the lamp housing 1 of the intersecting illumination area.

As shown in FIG. 3, it shows a state diagram of a plurality of lamp housings 1 disposed, and the lamp housings 1 have mutually overlapping illumination regions, wherein the light collecting units of the plurality of lamp housings 1 can face the intersection of the illumination regions. In the area to be detected 4, the required brightness of the area to be detected 4 is the A value, and the brightness given by the external environment is the B value. Therefore, after the light collecting unit 3 of the first lamp housing 1 (the number of the left side) senses the B value, the command is executed. The illumination unit 2 gives a value of A deduction B (assuming that the A value is greater than the B value) equal to the C illumination value, and the C illumination value causes the brightness sensed by the second lamp housing 1 to be the D value, so the second The brightness of the lamp housing 1 light-emitting unit 2 should be A minus B, the D value is equal to the E illuminating value, and the E value is such that the brightness sensed by the third lamp housing 1 concentrating unit 2 is F value, so the first The brightness of the three lamp housings 1 and the light-emitting unit 2 should be given as A minus B, and the F value is equal to the G-luminescence value. Thus, it can be understood that the lamp housing 1 can be calculated by the mutual cooperation of the to-be-detected area 4 and the light collecting unit 3. The difference is assigned to the function of the appropriate amount of luminescence If used in the structure of the solar panel, the saving energy of the solar panel lamp body can be effectively saved, and FIG. 3 is a side-by-side diagram for illustrative purposes. Of course, the plurality of lamp housings 1 are arranged in a plurality of rows, columns or irregular phases. When collocation, the amount of light that should be assigned to the difference is also changed.

 Then, as shown in FIG. 4, it shows that when the car passes through a plurality of arranged lamp housings 1, the first lamp housing 1 on the left side senses the brightness of the car lamp, and the light-emitting unit 2 reinforces or reduces the illumination. Brightness, and the first, second and third lamp housings 1 are covered by the intersection of the areas to be detected 4 (for example, the first and the two lamp housings 1 cover, the second and the third lamp housing 1 cover), so the first When the lamp housing 1 changes brightness, the second and third lamp housings 1 will gradually sense the brightness of the previous lamp housing 1 to give the car proper illumination, so that the driver can view the front of the car at an ideal viewing distance. There is a condition of brightness change, for the driver to see the road condition to avoid danger, and after the car passes, the lamp housing 1 can emit lower brightness to save energy.

And the concentrating unit 3 further includes a buffer unit 35 having a preset buffer value. When the concentrating unit 3 senses that the brightness change time of the area to be detected 4 is below the buffer value, The micro control unit 33 and the pulse width modulation unit 34 command the light emitting unit 2 not to adjust the brightness of the light. When the present invention encounters the area to be detected 4 for the ambient brightness to flash for a short time, the light collecting unit 3 commands the light-emitting unit 2 not to adjust the light-emitting brightness to avoid causing the state of the present invention to blink.

 When the brightness change time of the area to be detected 4 is sensed above the buffer value, the buffer unit 35 determines that there is a significant, non-transitory brightness change at the area to be detected 4, so that the buffer unit 35 cooperates with the micro control unit 33 to change the brightness. The values of time and brightness are integrated calculations, and the micro-control unit 33 and the pulse width modulation unit 34 instruct the light-emitting unit 2 to increase or decrease the light-emitting brightness. 5 is a graph of ambient brightness level-time, driving current value level-time, light projection area brightness level-time of the projection area of the present invention, and the projected area ambient brightness level refers to a brightness value given to the projection area by the environment, The driving current value level refers to the driving current value of the electro-mechanical corresponding brightness when the invention is implemented on the electronic machine, and the brightness level of the light projection area refers to the sum of the light projection and the ambient brightness of the projection area, so in the figure It can be seen that in the projection area (corresponding to the to-be-detected area 4 of the present invention), when the ambient brightness level is low, the light-emitting unit 2 should be supplemented with a higher projection brightness, and of course, the driving current value is also increased, but the light-emitting unit 2 is supplemented. As a result of the upper projection brightness matching the brightness of the projection area, the total brightness of the light projection area is kept at a preset constant value.
