Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments of the present specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

In order to solve the problems existing in the prior art, the embodiment of the present application provides a lighting module that imitates natural light, as shown in FIG. 1 , including:

The module housing 11, the module housing 11 has a first inner surface A and a second inner surface B that are perpendicular to each other;

a side-illuminated light guide plate 12 arranged in parallel with the second inner surface B;

a color light source 13 disposed on at least one side of the side incident light guide plate 12, the light emitted by the color light source 13 is directed to the side incident light guide plate 12;

The white light source 14 arranged in the module housing 11, the projection of the white light source 14 on the plane where the side incident light guide plate 12 is located falls outside the area where the side incident light guide plate 12 is located;

the first reflector 15 disposed on the first inner surface A is used to reflect the light emitted by the white light source 14 toward the second reflector 16;

The second reflector 16 disposed on the second inner surface B is used to reflect the light reflected by the first reflector 15 to the main surface of the side-entry light guide plate 12. The second reflector 16 At least part of the projection on the plane where the side incident light guide plate 12 is located falls outside the area where the side incident light guide plate 12 is located.

FIG. 2 shows the components related to optics in the lighting module provided in this embodiment, and the solution will be described below with reference to the light path diagram. Referring to FIG. 3 , the edge-entry light guide plate includes a main surface P parallel to the second inner surface B and a side wall Q disposed non-parallel to the main surface P.

The main surface P of the light guide plate. It can be seen from FIG. 3 that the light emitted from the white light source 14 is reflected twice, and then strikes the main surface P of the edge-type light guide plate 12 at an oblique angle. Since the material of the side-entry light guide plate 12 is transparent, the angle of light entering the side-entry light guide plate 12 is basically the same as the angle of exiting the side-entry light guide plate 12 , and the light exits at an oblique angle. Wherein, since the side-entry light guide plate can guide the light incident on the side wall, the light emitted by the above-mentioned color light source enters from the side wall Q of the side-entry light guide plate, and the light emitted by the color light source is guided by the side-entry type light guide plate. The light plate is evenly transmitted to each area of the side-entry light guide plate, so that the overall color of the light guide plate is uniform. When the light emitted by the white light source is transmitted through the side-entry light guide plate, the light emitted by the lamp is affected by the light emitted by the colored light source, and the light emitted by the lamp is the color of the light emitted by the colored light source.

Affected by geographical factors, natural light in different geographical locations often has different characteristics. Taking Beijing as an example, since Beijing is located in the northern hemisphere, the sunlight tends to irradiate the ground obliquely from the south. So, to people in Beijing, the light radiating obliquely from the south looks close to natural light. In the embodiment of the present application, the white light source is reflected twice and transmits the side-entry light guide plate at an oblique angle, so that the outgoing light can be close to the inclination angle of natural light, so that the outgoing light looks close to natural light.

Specifically, the lighting module may include a communication module for acquiring weather information at the location, for example, the weather information may include sunny, cloudy, cloudy, thunderstorm, etc., and send the weather information to the color value control module. The color value control module of the lighting module can adjust the color of the light emitted by the color light source according to the obtained weather information, so that the color presented by the light guide plate is close to the color of the sky where the lighting module is located. For example, in sunny weather, the light emitted by the color light source is biased toward orange-red, and in rainy weather, the light emitted by the color light source is biased toward gray-blue, etc.

In addition, the lighting module may further include a time module communicatively connected to the color value control module for sending time information to the color value control module; the color value control module for receiving time information according to The color value of the color light source is controlled, so that the color light source emits a spectrum corresponding to the time information, so as to adjust the color of the light emitted by the color light source according to time.
