Embodiment 1

[0033] Embodiment 1: as figure 1 As shown, an adjustable illuminating lamp imitating natural light includes a light source 1, a driving power source 2 electrically connected to the light source 1, a control device 3 for controlling the driving power source 2, and a time signal generator connected to the control device 3 4.

[0034] The light source 1 is a combination light source, including a first sub-light source and a second sub-light source, both of which are white LEDs. The C / P value of the light emitted by the first sub-light source is greater than 3.0, and the C / P value of the light emitted by the second sub-light source is less than 2.5.

[0035] In order to achieve the C / P value required by the combined light source to imitate the natural light effect, the C / P value of the two sub-light sources must be relatively high, and the relative spectral power (intensity) in the range from 400nm to 520nm is relatively high; relatively low (or even zero). Such as figure 2 The...

Embodiment 2

[0040] Embodiment 2: The luminescent light source 1 includes red LED, green LED, and blue LED, wherein the C / P value of the red LED is less than 1.0, the C / P value of the green LED is less than 2.0, and the C / P value of the blue LED is less than 1.0. Greater than 3.0. The red LEDs, green LEDs, and blue LEDs are respectively composed of light sources with a monochromatic band spectrum, or light sources with a wide-band spectrum in the visible region. Other respects are with embodiment 1. Specifically, for example, the C / P value of a red LED is 0.5, the C / P value of a green LED is 2.0, and the C / P value of a blue LED is 3.5. Different duty ratios output from the control device 3 to the driving power supply 2 can be used to obtain different C / P values ​​between 0.5 and 3.5 to obtain a natural light source.

Embodiment 3

[0041] Embodiment 3: a blue cut-off optical device is added in front of the outgoing light of the second sub-light source. The cut-off wavelength of the optical device is between 480nm and 560nm, which prevents light that is smaller than the cut-off wavelength from being emitted, and light that is greater than the cut-off wavelength can Emanate from sub-sources. The optical device can be a transmission device (such as a filter or a filter film), or a reflection device (such as a mirror or a reflection film). Other aspects are the same as embodiment 1 or embodiment 2.

Abstract

The invention provides an adjustable illuminating lamp capable of imitating natural lights, comprising a light-emitting light source, a driving power supply, a control device and a time signal generator, wherein the driving power supply is electrically connected with the light-emitting light source; the control device is used for controlling the driving power supply; the time signal generator is connected with the control device in a signal manner; the light-emitting light source at least comprises a first secondary light source and a second secondary light source; a C / P (Citopic) value of emitted lights of the first secondary light source is more than 3.0 and the C / P value of the emitted lights of the second secondary light source is less than 2.5; the C / P values which are changed along with time and light strength information are stored in the control device; time information is sent to the control device by the time signal generator and a control signal is output to the driving power supply by the control device according to the input time information; the driving power supply is used for respectively controlling the strength of all the secondary light sources, so that a light source with the corresponding C / P value and light strength is formed by the light-emitting light source. The adjustable illuminating lamp capable of imitating the natural lights, provided by the invention, has the substantial characteristics of being beneficial to human health and being particularly applicable to habitation environments including indoor offices, homes and the like, and closed environments including airplanes, submarines for illumination and the like.

Description

technical field [0001] The invention relates to an illuminating lamp beneficial to human health, in particular to an adjustable illuminating lamp imitating natural light suitable for living environments such as indoor offices and families and closed environments such as aircraft and submarine lighting. Background technique [0002] In daily life, the jet lag of passengers during global voyages, the incompatibility of night shift workers during shift changes, the day and night of astronauts in space, etc., all prove the physiological discomfort caused by the lack of normal natural light exposure of the human body. [0003] The use of LED light sources for lighting has many advantages, such as energy saving, environmental protection, long life, fast response, resistance to switch shocks, and easy light distribution. Recently, due to the improvement of the light efficiency of LED light sources and the rapid decline in prices And accelerate the penetration into the field of indo...
