Example 1

Referring to fig. 1-6, the present invention provides a DALI protocol-based healthy lighting demonstration system, comprising:

the programmable controller 2 is in communication connection with the signal generator 1, the tellurion system and the DALI lighting control system;

a signal generator 1 for sending a demonstration instruction to the programmable controller 2;

the globe system is used for performing revolution simulation and/or rotation simulation according to the demonstration instruction and sending a feedback instruction to the programmable controller 2;

the DALI lighting control system is used for triggering corresponding natural light deduction scenes on the globe system at least according to the feedback instruction or triggering healthy lighting deduction scenes according to the demonstration instruction.

Specifically, light entering the human eye, in addition to providing visual functions, non-imaging light stimulates melatonin secretion, affecting physiological and psychological phenomena such as circadian rhythms, heart rate, alertness, electroencephalogram, body changes, pupil constriction, etc., and this light effect is called a non-visual effect. The non-visual illumination is the root of forming a rhythm, in order to better know the generation of the rhythm, the color temperature change of the day and night, the formation of the spring, the summer, the autumn and the winter, and the like, the invention combines a DALI illumination control system to deduce the formation process of natural light through a revolution and rotation model of a globe system, further combines the basic theory of healthy illumination, such as the human habit of 'high color temperature and high illumination, low color temperature and low illumination', to correct the artificial natural light, so that the artificial natural light not only has the connotation of healthy illumination, but also can be more comfortable and healthy according to different people; therefore, the knowledge of popular science illumination is convenient for deducting the formation and theoretical basis of healthy illumination to people.

Preferably, the globe system comprises:

the revolution programmable motor 4 is in communication connection with the programmable controller 2 through the revolution motor encoder 3 so as to enable revolution simulation of the globe to rotate around the axis of the yellow track;

and the autorotation programmable motor 6 is in communication connection with the programmable controller 2 through an autorotation motor encoder 5 so as to enable autorotation simulation of the globe to rotate around the equatorial axis of the globe.

It is well known that the earth makes one revolution around the sun for about 365 days, known as revolution. Because the yellow road and the equator are inclined by 23.26 degrees, the sunlight direct angle can be changed between the north latitude 23.26 degrees and the south latitude 23.26 degrees, and correspondingly, the incident angle of the sunlight irradiation surface on a certain place on the earth can be correspondingly changed, so that the sun-light irradiation surface can form spring, summer, autumn and winter. The rotation of the earth is that every 15 degrees from the meridian is a time zone, 24 meridians are 24 time zones, and the rotation of the earth is 24 hours for a week, so that day and night changes, sunrise and sunset can be formed.

In the invention, the revolution diameter is too large to demonstrate, and the invention takes the axis of the yellow track of the globe as the rotation axis to simulate the revolution of the earth by myopia. Further, the globe system is used as a demonstration, and in order to facilitate understanding of the effect of light intensity and color temperature formed by revolution and rotation in a short time, the speed of rotation and revolution can be appropriately accelerated to easily explain the change of air temperature in each season, the change of color temperature of sunrise and sunset, and the like to people. For example, at sunrise and sunset, sunlight is not directly incident on the ground but obliquely incident on the earth through a long cloud, and at this time, a spectrum of a high color temperature is diffused and a low color temperature portion is diffused to the ground, thereby forming a color temperature change of sunrise and sunset.

Preferably, the signal generator 1 includes a revolution button 101, a rotation button 102, a summer artificial lighting button 103, a winter artificial lighting button 104, a daily pattern button 105, or further includes a laser button 106 and a laser light source 107.

Specifically, the signal generator 1 may be an input device directly used as the programmable controller 2 in the form of a control panel, or may be a wireless communication between the signal generator and the receiver 201 of the programmable controller 2 in the form of a remote controller. Each button on the signal generator 1, except for the daily mode button 105, corresponds to a presentation instruction, and all presentation instructions can be superimposed. For example:

when the revolution button 101 is pressed for a short time, the globe revolves for 90 degrees at the current position, and then the four stop positions (see fig. 4 for details) respectively correspond to the four seasons of spring, summer, autumn and winter in a certain area on the globe; when the revolution button 101 is pressed for a long time (more than 2 seconds, the same applies to the following), the globe keeps revolving continuously; and when the revolution button 101 is pressed for a long time, the globe stops the revolution;

when the autorotation button 102 is pressed for a short time, the globe stops at a circle; and when the rotation button 102 is pressed for a long time, the globe keeps rotating continuously; when the rotation button 102 is pressed for a long time, the globe stops rotating;

as the revolution and/or rotation of the globe proceeds, under the action of the DALI lighting control system: when the summer man-made illumination button 103 is pressed, a deduction scene of summer natural light is correspondingly triggered on the globe, and a summer light supplementing scene is triggered according to the habit of the human being; when the winter man-made illumination button 104 is pressed, a deduction scene of winter natural light is correspondingly triggered on the globe, and then a winter light supplementing scene is triggered according to the habit of the man, namely, high color temperature and high illumination, low color temperature and low illumination;

in the process of demonstrating explanation, when the laser button 106 is pressed, the laser light source 107 emits a red light beam, and the explanation person can indicate the red light beam to the corresponding position on the globe at the moment so as to facilitate explanation; after the presentation is completed, the globe exits the presentation mode to restore to the daily light scene when the daily mode button 105 is pressed.

Preferably, in the DALI lighting control system, the addressable lighting interface is communicatively connected to the programmable controller 2 through the DALI gateway 7, and uses the scene of the DALI system to control both the illuminance and the color temperature of the system, so as to achieve the effect of synchronizing the artificial light with the natural light.

Specifically, in the invention, the DALI lighting control system triggers a corresponding natural light deduction scene on the globe according to the revolution and/or rotation simulation process of the globe, so that artificial light and natural light are always kept synchronous in the formation process of deduction natural light. The DALI lighting control system further includes a DALI bus power supply 8, a DALI bus 17, an RS485 bus 18, and related lighting devices and driving elements, and the specific connection manner thereof may be seen in fig. 1. For example, the lighting device and the driving element may comprise a one-to-one correspondence: the first light emitting device 13 and the first DALI driver 9, the second light emitting device 14 and the second DALI driver 10, the third light emitting device 15 and the third DALI driver 11, the fourth light emitting device 16 and the fourth DALI driver 12.

Preferably, the DALI lighting control system further comprises:

a direct light simulation device, which is arranged at one side of the globe, consists of a fourth light emitting device 16 with ultra-high color temperature and a fourth DALI driver 12, and directly projects simulated direct light to the globe through a color filter 19, wherein the color filter 19 presents a color filtering structure from the outer side to the center, and the color filtering structure gradually changes from low color temperature to high color temperature in a light transmission way;

the diffusion light simulation device is suspended above the globe and is formed by combining a plurality of groups of light-emitting devices simulating the black body curve of sunlight, so as to be used for projecting simulated scattered light of various different scenes to the globe below the diffusion light simulation device according to the spectrum curve of sunlight.

Specifically, the illumination can be divided into direct light and scattered light, and the direct light refers to light of the sun directly projected onto the ground in parallel rays; the scattered light is light that is diffused from the sky to the ground after sunlight passes through air molecules, dust, water drops and other substances. The earth is surrounded by thick clouds, and even if there is no direct sunlight, the sky is brighter due to diffuse reflection of the clouds. In the illumination on the ground on a sunny day, the direct light is about 63% and the scattered light is about 37%.

In the invention, the direct light simulation equipment for simulating direct solar light adopts a high-power small-beam angle LED spotlight, and the color temperature value and the illumination value of the LED spotlight are fixed, wherein the color temperature is 6500K and the power is 200W; or when the direct light simulation equipment selects a D65 simulation sunlight system, the color temperature value of the direct light simulation equipment is D65, and the illumination value is adjustable. Therefore, the relative irradiation angle of the LED spot lamp on the globe in the high-latitude area is small, and the daytime is shorter; in contrast, the relative irradiation angle of the LED spot light to the globe in the low-latitude area is large, and the daytime time is long. Wherein D65 is 6500K color temperature closest to sunlight given by CIE international standard, and the color temperature reaching the room is only 5500K when the actual sunlight is subjected to cloud filtering refraction.

Due to different latitudes, the distance of sunlight passing through an air layer is different, so that the color temperature on each latitude is different; second, the distance that sunrise and sunset sunlight passes through the air layer is also different in 24 hours, thereby forming a difference in color temperature in one day. In the invention, before the lampshade of the LED spotlight, the light of the LED spotlight is driven to the peripheral side of the globe by the action of the color filter 19 to show the effect of low color temperature, such as sunrise and sunset of sunlight; the LED spot light is directly irradiated on the central area of the globe to show the effect of high color temperature, as if the sun is at noon, and the sunlight color temperature change curve shown in fig. 5 can be seen. The color filter 19 may be a transparent film coated with a color temperature gradient coating, i.e. a material with gradually higher color temperature is coated along the radial circumference to the center of the transparent film.

As a preferred example of the present invention, the diffusion light-emitting device may be a soft film lamp strip simulating cloud scattering light with a small area of cloud layer, which is formed by covering a high, medium and low color temperature lamp strip capable of simulating a black body curve of sunlight with a teflon film. Wherein each color temperature lamp strip can be two hundred meters long and ten watts per meter, for example.

Preferably, the diffusion light simulation device issues a plurality of instructions according to the scene setting of revolution simulation and/or rotation simulation, and the change process of each instruction is completed by using the delay function of the DALI system.

Specifically, the color temperature and the sunset time of sunrise and sunset are different in different latitudes, and an example is given here: the change of the midday illumination in sunny days in summer, the illumination of the open field is about 10 kaleidos, the illumination in sunny days in winter is about 2 kaleidos, and the illumination in overcast and rainy days only accounts for 20-25% of sunny days. The color temperature of sunrise and sunset changes, the sunrise time is 1850-2000K, the sunrise time is 2380-3000K after half an hour, the sunshine after one half an hour of sunrise is 3500K, the sunshine after one half an hour of sunrise is 4000K, the sunshine after two hours of sunrise is 4400K, the sunshine of 4:30 pm is 4750K, the sunshine of 3:30 pm is 5000K, and the direct sunlight of noon is 5300K-5550K.

In the invention, the efficiency of the diffusion light simulation device adopting the light mixing mode can be very high. Of course, four light sources using rgb+d65 can also produce dimming hues that vary within the blackbody curve.

As a preferred example of the present invention, the present application may set at least 12 scenes to correspond to sunrise, noon and sunset in spring, summer, autumn and winter, respectively, according to scenes 0 to 5 and scenes 7 to 12 shown in fig. 6. Wherein the instructions of each period are linked to the diffuse light simulation device through the DALI gateway 7 to make the light intensity and color temperature in each scene different, so that the real changing scene of the natural light can be deduced more accurately under the respective seasonal changes. Natural light of course includes, but is not limited to, sunrise, noon and sunset, where sunrise and sunset shadows are produced by direct light analog devices.

Preferably, the addressable lighting interface comprises at least the following four device addresses:

a first device address and a second device address, both corresponding to the diffuse light simulation device, to vary light intensity and color temperature over different time periods;

a third device address corresponding to the diffusion light-emitting device to change at least the light intensity of the middle region of the black body curve of the sunlight or also the color temperature with different time periods;

and the fourth equipment address corresponds to the direct light simulation equipment, and the color temperature value and the brightness value of the fourth equipment address are fixed, or when the direct light simulation equipment selects a D65 sunlight simulation system, the color temperature value of the fourth equipment address is D65 and the illuminance value of the fourth equipment address is adjustable.

Specifically, the high, medium and low color temperature light bands may be composed of the first light emitting device 13, the second light emitting device 14 and the third light emitting device 15, and specifically, the number may be selected according to the area size of the cloud scattered light in the simulated cloud layer, and when the power is large, the addressable lighting interface may be a repeated address or multiple addresses. The range of the color temperature variation value of the simulated ambient light lamp can be as follows: 1850K-6500K, the illumination change value range can be 80Lux-900Lux; the color temperature value of the light supplementing lamp can be constantly 1600K, and the illumination change value range can be 0Lux-130Lux; the color temperature value of the simulated sunlight lamp can be constant at 6500K, and the illuminance value is constant at 2000Lux.

Preferably, the diffuse light simulation device is further responsive to a personal lighting demonstration instruction issued via the summer personal lighting button 103 and/or the winter personal lighting button 104 to trigger brightness and illuminance adjustment in a healthy lighting deduction scene.

Specifically, the invention combines the revolution and rotation model of the globe system and the DALI lighting control system to deduce the formation process of natural light, so as to correct the artificial natural light by combining the basic theory of healthy lighting, such as human habit of 'high color temperature and high illumination, low color temperature and low illumination', on the basis of correctly deducting the effect of natural light and keeping the artificial light synchronous with the natural light, so that the artificial natural light has the connotation of healthy lighting, can be different from person to person, and is more comfortable and healthy; therefore, the knowledge of popular science illumination is convenient for deducting the formation and theoretical basis of healthy illumination to people. Specifically, the present invention relates to a method for manufacturing a semiconductor device.

In summer and winter, natural light or artificial natural light does not accord with healthy illumination, and according to the habit of human beings of 'high color temperature high illumination and low color temperature low illumination', a healthy illumination button, such as a summer human factor illumination button 103, can be arranged on the signal generator 1 so as to increase yellow light in winter with low illumination; and/or winter human factor illumination buttons 104 to reduce luminous flux during high summer illumination. For example:

in the summer light supplementing mode, the color temperature of the simulated environment light lamp is adjusted to 6000K, the illuminance is adjusted to 300Lux, and the illuminance of the light supplementing lamp is adjusted to 0, so that the luminous flux is reduced in the summer under high illuminance, namely, the scene corresponds to the scene 6 in fig. 6; in the winter light supplementing mode, the color temperature of the simulated ambient light lamp is regulated to 2700K, the illuminance is regulated to 300Lux, and the illuminance of the light supplementing lamp is regulated to 0, so that the luminous flux is increased in the winter under low illuminance, namely, the scene 13 in fig. 6 is corresponded.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention should be assessed accordingly to that of the appended claims.
