Description

OLED multi-light-source flat lamp based on OLED health illumination technology

Technical Field

The invention relates to an OLED multi-light-source flat lamp based on an OLED health illumination technology.

Background

The operation command center is generally responsible for important work such as operation planning, command control, operation guarantee scheduling and the like, is a nerve center and a brain in the whole operation, has extremely high strategic position in ancient times of military combat, and therefore becomes a primary destruction and attack target of enemies. In order to avoid investigation and attack of enemies, the combat command center is generally hidden underground in all countries, so that when an emergency is encountered, the fighters can normally command the underground command post to combat and carry out long-term continuous battles with the enemies.

For the purpose of concealment, underground command places are relatively closed and cannot be in contact with sunlight, and all illumination is artificial illumination. The light quality of the illumination is particularly important as the fighter is required to work in this confined space environment for a long time. The fighters are in the lighting environment with fixed light color and constant brightness for a long time, and the physical and psychological health conditions of the fighters are seriously harmed due to the lack of natural illumination. Through the natural evolution of thousands of years, people form a life law based on sunlight. The sunlight is 3200K red similar to candle light in the day, and the color temperature is very low. As the sun rises, the color temperature of the sunlight also rises. At noon, the sky is very white to the sun. The color temperature is 5000K, the sky looks more bluish and white as the color temperature increases. After 2 pm, the color temperature starts to decrease again, and when the evening comes, the red low color temperature is returned, and the night screen falls. With the change of sunlight in one day, the activities of people also change from rest to activity and then return to rest, and the activities change repeatedly. If a person is in a lighting environment with constant single light color for a long time, physiological and psychological discomforts such as vexation, hypodynamia, somnolence, low mood, depression and the like are easily generated, so that the attention is reduced, the reaction is delayed, the error rate is increased, and serious persons can also cause certain damage to the cognitive function of professionals, thereby directly influencing the fighting efficacy.

Therefore, the illumination of the underground command place can simulate the change of natural light color in morning, noon and night under natural conditions, and finger fighters can feel the cycle change of day and night, so that the physiological rhythm of the human body is adjusted, and the physical and psychological health of the finger fighters is ensured.

Detailed Description

The invention will be described in further detail below with reference to specific embodiments and drawings. Here, the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 3, an OLED multi-light source flat-panel lamp based on OLED health lighting technology is shown. The LED light source module outputs soft comfortable white light which accords with target light color and brightness through the light homogenizing and mixing effects of the light guide plate, the outer surface of the OLED diffuse reflection and the diffusion plate; the luminosity detection module detects the light intensity output by the lamp and is used for carrying out closed-loop control on the brightness of the panel lamp, so that the control precision is improved. The dimming control module acquires current ambient temperature and humidity information through the room temperature detection module, acquires current time information through the clock module, and calculates and outputs a light source control signal to the light source module through a built-in control algorithm according to the ambient temperature, humidity and time information, so that the dimming process is completed. The dimming control module can automatically regulate and control the mixed light color of the cold white LED and the warm white OLED in the light source module through a built-in algorithm, so that the mixed light color meets the white light requirement defined by a light color regulation curve and CIE (Committee-absorption-interference) and the brightness of the flat lamp is regulated in a linkage manner under the condition of meeting the light color, and in addition, the dimming control module can also receive a signal from the room temperature detection module and regulate the light color and the brightness of the light source module in real time according to the light color/temperature sensitive characteristic of a person; the power supply module supplies power to each module.

Fig. 2 is a structural diagram of an OLED multi-light-source flat-panel lamp according to the OLED health lighting technology. The warm white OLED is positioned at the bottom of the flat lamp and directly emits soft warm white light; the cold white LED light source component is arranged on the side face of the lamp and emits cold white light, and the cold white light is mixed into required white light after passing through the light guide plate, the outer diffuse reflection surface of the OLED light source component and the diffusion plate.

As shown in fig. 3, which is a control flow chart of the OLED multi-light-source flat lamp conforming to the OLED health lighting technology, the system controls the color temperature and brightness of the light source module according to time, and simultaneously determines the obtained color temperature value, when it is determined that the ambient temperature sensed by the indoor comprehensive detection module is lower than 15 ℃, the color of light is changed to 4500K, otherwise, the color temperature is set to 5000K; when the environment temperature is higher than 30 ℃, the room temperature detection module changes the light color to 4000K, otherwise, the color temperature CCT is between 3000K and 4000K and dynamically changes; if in the middle of the day, the color of the light will change as per the requirements of FIG. 3.

Modern medical research proves that circadian rhythm changes exist in all physiological functions of a human body. A rhythm vibration body controlling the human circadian rhythm is present at the SCN. The SCN vibrating body is positioned above the hypothalamic visual cross, senses the alternation of external day and night illumination environment through the retina and adjusts the self day and night rhythm to be synchronous with the vision cross. It is becoming appreciated that illumination has physiological effects in addition to the effects on human vision, and that studies on the effects of light on the human body from a physiological perspective have become a new direction in the field of illumination. The light color and brightness control strategy of the invention is verified by man-machine work efficiency test and is installed in an underground command place, and the biological effect of light is utilized to maintain the physiological rhythm of the fighter.
