Abstract
Description
Technical Field
[0001] This application relates to the field of lighting technology, and in particular to a light source module and a luminaire. Background Technology
[0002] Currently, household lighting fixtures generally have a larger beam angle in order to cover a larger lighting space. However, accent lighting emphasizes the lighting atmosphere of a local space and covers a smaller lighting area, so the beam angle of such lighting devices is generally smaller. To meet different scene requirements, different beam angles can be obtained by selecting optical devices with different beam angles or adjustable focal lengths.
[0003] The above methods of changing the light emission angle are basically based on a single angle set in advance. However, the light intensity requirements of lighting fixtures vary in different scenarios. For example, reading scenarios require higher light intensity, while sleeping scenarios require lower light intensity. The above lighting fixtures cannot meet the more diverse scenario requirements.

[0027] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0028] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.
[0029] The light source module and lamp are described in detail below through specific embodiments:
[0030] Reference Figures 1 to 7 As shown, some embodiments of this utility model provide a light source module, including a lamp board 1, on which at least two sets of light-emitting elements 2 are provided, and the light emission brightness of each set of light-emitting elements 2 is independently adjustable; each set of light-emitting elements 2 includes at least one light-emitting element 3, and each light-emitting element 3 is covered with a lens 4, and the diffusion angle of the lens 4 covering at least two sets of light-emitting elements 3 is different.
[0031] The light source module provided in this application includes a lamp board 1, on which at least two sets of light-emitting elements 2 are provided. Among all the light-emitting elements 2, at least two sets of light-emitting elements 3 are covered with lenses 4 with different diffusion angles. One set of light-emitting elements 2 has a more concentrated light emission angle. When the brightness of the concentrated light is large, it can meet the local lighting needs. The other set of light-emitting elements 2 has a more dispersed light emission angle. When the brightness of the dispersed light is large, it can expand the lighting area.
[0032] The brightness of each group of light-emitting elements 2 is independently adjustable. That is, by individually lowering the brightness of one group of light-emitting elements 2, or individually raising the brightness of one group of light-emitting elements 2, or simultaneously lowering the brightness of one group of light-emitting elements 2 and raising the brightness of another group of light-emitting elements 2, the brightness of the lighting can be adjusted in different lighting scenarios, thereby meeting diverse usage needs.
[0033] It should be noted that the brightness of the light-emitting element 2 can be adjusted to the lowest level of not emitting light. At this time, the light source module is illuminated by the other light-emitting elements 2 besides this group of light-emitting elements 2, so that the light source module can obtain the illumination angle corresponding to the other light-emitting elements 2.
[0034] Of course, each set of light-emitting elements 2 can also be individually controlled to turn on and off to obtain different lighting angles, thus making it suitable for different usage scenarios.
[0035] In specific implementations, the number of groups of light-emitting elements 2 can be two, three, four, or more. For example, refer to... Figure 1 and Figure 2 As shown, the number of light-emitting elements 2 is two groups, namely the first group of light-emitting elements 21 and the second group of light-emitting elements 22. Specifically, the number of light-emitting elements 3 in the first group of light-emitting elements 21 can be the same as or different from the number of light-emitting elements 3 in the second group of light-emitting elements 22. The arrangement of the light-emitting elements 3 in the first group of light-emitting elements 21 and the second group of light-emitting elements 22 can be sequential or alternating, depending on the needs. For example, the light-emitting elements 3 in the first group of light-emitting elements 21 and the second group of light-emitting elements 22 can be arranged side by side in a one-to-one correspondence, or they can be arranged alternately.
[0036] In some embodiments, each group of light-emitting elements 2 includes a light-emitting element 3 of one color, and the light-emitting elements 3 of different groups have the same color.
[0037] Reference Figure 1 and Figure 2As shown, the light-emitting elements 3 in different groups are of the same color, and the light source module can emit illumination light of one color. After the light from all groups of light-emitting elements 2 is superimposed, different illumination angles can be obtained by adjusting the brightness of different groups, thus making them suitable for different application scenarios. Specifically, when the brightness of one of them is adjusted to zero, the lens 4 covering the other corresponds to the limit range of the illumination angle, which can be set according to actual needs.
[0038] In other embodiments, each group of light-emitting elements 2 includes a light-emitting element 3 of one color, and the colors of the light-emitting elements 3 in different groups are different. (Refer to...) Figure 3 and Figure 4 As shown, different groups of light-emitting elements 3 have different colors. When different colors of light are superimposed, the lighting light is more atmospheric. That is to say, when multiple different colors of light are superimposed, when the brightness of one part of the light-emitting elements 3 increases, the lighting light emitted by the light source module will be biased towards the mixed light color of that part of the light-emitting elements 3. When the brightness of one part of the light-emitting elements 3 decreases, the lighting light emitted by the light source module will be biased towards the mixed light color of another part of the light-emitting elements 3, thereby obtaining lighting light with different color temperatures.
[0039] For example, different groups of light-emitting elements 3 can emit white light and yellow light. The light-emitting element 3 that emits white light is adapted to a more concentrated lens 4, and the light-emitting element 3 that emits yellow light is adapted to a more dispersed lens 4. When the brightness of the light-emitting element 3 that emits white light is increased, under the action of the lens 4, the light source module can emit a more concentrated and brighter illumination light, that is, the illumination light can be more biased towards white light; while when the brightness of the light-emitting element 3 that emits yellow light is increased, under the action of the lens 4, the light source module can emit a more dispersed and dimmer illumination light, that is, the illumination light can be more biased towards yellow light.
[0040] In other words, compared to simply adjusting the brightness of the light-emitting element 3, the light source module of this application can further expand the color temperature adjustment range, thereby meeting various light emission effect requirements and improving product performance.
[0041] In other embodiments, each group of light-emitting elements 2 includes at least two different colors of light-emitting elements 3, and the brightness of the different colors of light-emitting elements 3 in the same group is independently adjustable. That is to say, each group of light-emitting elements 2 can achieve the adjustment of the color temperature of the illumination light. The light-emitting elements 3 in different groups of light-emitting elements 2, together with different lenses 4 covering them, can enable different groups of light-emitting elements 2 to emit illumination light with different color temperature ranges, thereby adapting to more application scenarios.
[0042] Furthermore, referring to Figure 5As shown, the lenses 4 covering the light-emitting elements 3 of different colors in the same group have the same diffusion angle, and their diffusion angles are different from those of the lenses 4 covering the light-emitting elements 3 in other groups. In other words, by individually lowering the brightness of one color, or individually raising the brightness of one color, or simultaneously lowering the brightness of one color and raising the brightness of another color, the color temperature of the lighting light can be adjusted in different lighting scenarios, thereby meeting diverse usage needs.
[0043] Reference Figure 6 As shown, the diffusion angles of the lenses 4 covering the light-emitting elements 3 of different colors in the same group are different, and they are also different from the diffusion angles of the lenses 4 covering the light-emitting elements 3 in other groups. It can be understood that by setting lenses 4 with different diffusion angles, compared with the method of adjusting the color temperature by adjusting the brightness of the light-emitting elements 3 alone, the light source module of this application can further expand the color temperature adjustment range, thereby meeting various light output effect requirements and improving product performance.
[0044] For example, each group of light-emitting elements 2 includes light-emitting elements 3 of different colors, and there are multiple light-emitting elements 3 of each color. The lenses 4 covering the light-emitting elements 3 of the same color have the same diffusion angle so as to jointly form an illumination light of one color to meet the lighting requirements. Furthermore, the lenses 4 covering the light-emitting elements 3 of different colors in the same group have different diffusion angles so as to expand the color temperature adjustment range by adjusting the current and setting lenses 4 with different diffusion angles.
[0045] For example, refer to Figure 6 As shown, two sets of light-emitting elements 2 are provided on the light panel 1, and each set of light-emitting elements 2 has two different colors of light-emitting elements 3. Correspondingly, four kinds of lenses 4 with different diffusion angles are provided to meet a wider range of color temperatures.
[0046] In a specific implementation, the light-emitting elements 3 of different colors in the same group include at least white light bulbs 31 and colored light bulbs 32. The diffusion angle of the lens 4 covering the white light bulb 31 is smaller than the diffusion angle of the lens 4 covering the colored light bulb 32.
[0047] In other words, the white light LED 31 is adapted to the lens 4 with a more concentrated diffusion angle, while the colored light LED 32 is adapted to the lens 4 with a more dispersed diffusion angle. When the brightness of the white light LED 31 is increased, under the action of the lens 4, the light source module can emit a more concentrated and brighter illumination light, that is, the illumination light can be more biased towards white light; while when the brightness of the colored light LED 32 is increased, under the action of the lens 4, the light source module can emit a more dispersed and dimmer illumination light, that is, the illumination light can be more biased towards colored light, thus meeting the usage needs of using white light in reading scenarios or using colored light in sleeping scenarios.
[0048] In some embodiments, refer to Figure 5 As shown, there are multiple light-emitting elements 3 of different colors in the same group, and the light-emitting elements 3 of different colors in the same group are alternately arranged in at least one direction, which makes the lighting light of multiple colors more uniform and improves the user experience.
[0049] Furthermore, referring to Figure 3 As shown, the light-emitting elements 3 of different groups of light-emitting elements 2 are of different colors, and multiple light-emitting elements 3 of different colors in different groups can also be arranged alternately in at least one direction, so that the illumination light of different color temperatures can be evenly distributed.
[0050] It should be noted that there are multiple sets of light-emitting components 2, each of which contains multiple light-emitting elements 3. The multiple light-emitting elements 3 are arranged in an array. Any two adjacent light-emitting elements 3 in each row and column can be light-emitting elements 3 of two colors that are alternately distributed. That is, light-emitting elements 3 of different colors are alternately arranged in multiple directions. Of course, the multiple light-emitting elements 3 can also be arranged alternately in one direction, row by row or column by column. This application does not limit this, as long as it can ensure that the illumination light emitted by the light source module is uniformly mixed.
[0051] In some embodiments, the lenses 4 covering different groups of light-emitting elements 3 have different diffusion angles, and the different groups of light-emitting elements 3 are alternately arranged along at least one direction, so that the illumination light at various different angles can be mixed more evenly, thereby improving the user experience.
[0052] For example, refer to Figure 1 As shown, the light-emitting elements 3 in different groups are of the same color, and the light source module can emit illumination light of one color. When the brightness of different groups is adjusted, different illumination angles can be obtained. When the brightness of one of them is adjusted to zero, the lens 4 covering the other corresponds to the limit range of the illumination angle. The light-emitting elements 3 in different groups and the lenses 4 with different diffusion angles are alternately arranged in at least one direction, which can avoid large contour partitions of light and ensure product performance.
[0053] In some embodiments, refer to Figure 7 As shown, the light source module includes a driving module 5, which is electrically connected to each group of light-emitting elements 2. The driving module 5 is used to adjust the current flowing through each group of light-emitting elements 2, thereby adjusting the brightness of each group. Specifically, different current paths are passed through each group of light-emitting elements 2, allowing the driving module 5 to individually adjust the current of each group, thus adjusting the light brightness according to different scene requirements. With the cooperation of the lens 4, different brightness and color temperature lighting can be obtained according to actual needs.
[0054] In a specific implementation, the light source module also includes a sensor module. The sensor module can identify user behavior, and the drive module 5 can make active adjustments based on the information identified by the sensor module. For example, when it is detected that the user is reading, the current in the light-emitting element 3 corresponding to the lens 4 with a smaller diffusion angle is increased to achieve focusing. When different sizes of books are detected, different focusing angles can be adjusted by adjusting the angle of the illumination light. Of course, the light source module can also be actively adjusted according to the user's needs, but this application does not limit this.
[0055] In some embodiments, continue to refer to Figure 7 As shown, the light source module includes multiple lamp panels 1, each lamp panel 1 having at least two sets of light-emitting elements 2. The light-emitting elements 2 on each lamp panel 1 are electrically connected to the drive module 5. Specifically, multiple lamp panels 1 can be configured according to actual needs to enhance illumination brightness. It is understood that the brightness of each set of light-emitting elements 2 on the multiple lamp panels 1 can be adjusted independently. When the diffusion angles of the lenses 4 on different sets of lamp panels 1 are different, even if the angle of the illumination light is further increased, i.e., the illumination light is further dispersed, a certain level of illumination can still be guaranteed through the superposition of multiple lamp panels 1.
[0056] Other embodiments of this application provide a lamp fixture including a light source module as described in any of the above embodiments, the light source module being disposed on the lamp fixture body.
