Description
本发明属于照明装置技术领域,尤其涉及一种光源模组。The invention belongs to the technical field of lighting devices, and in particular relates to a light source module.
当前,一种能够调整所发出光线色温的照明装置应用广泛。现有技术中,这种照明装置的光源模组一般包括至少两组发光单元,位于同组的发光单元的色温相同,位于不同组的发光单元的色温不同。每组发光单元均具有独立的供电回路,通过选择性的导通和断开这些供电回路,使得光源模组能够发出不同色温的光线,实现匹配不同色温要求的环境。Currently, a lighting device capable of adjusting the color temperature of emitted light is widely used. In the prior art, the light source module of the illumination device generally includes at least two groups of light-emitting units, and the color temperatures of the light-emitting units in the same group are the same, and the color temperatures of the light-emitting units located in different groups are different. Each group of light-emitting units has an independent power supply circuit. By selectively turning on and off these power supply circuits, the light source module can emit light of different color temperatures to achieve an environment that matches different color temperature requirements.
然而,由于该种照明装置内各组发光单元均具有独立的供电回路,在选择性导通和断开这些供电回路来调整照明装置所发出光线色温过程中,会出现因为所导通的供电回路的数量不同而导致照明装置的功率不恒定的情况,这种功率不恒定的弊端会破坏照明装置的照明稳定性,使得照明装置所发出光线的光强忽大忽小,造成人眼观感上极度不适。However, since each group of illumination units in the illumination device has an independent power supply circuit, during the process of selectively turning on and off the power supply circuits to adjust the color temperature of the light emitted by the illumination device, a power supply circuit that is turned on may occur. The difference in the number of lighting causes the power of the lighting device to be not constant. The disadvantage that the power is not constant will destroy the lighting stability of the lighting device, so that the light intensity of the light emitted by the lighting device is suddenly large and small, resulting in an extreme sense of human eyes. Discomfort.

需要说明的是,光源模组100可以应用于照明灯具(未图示),如吸顶灯内。当照明灯具启动后,光源模组100内的发光单元3所发出光线通过透镜1边缘部11的光入射面112后发生一次向外折射,光
线在透镜1边缘部11内沿直线延伸,当光线抵达光出射面113后发生二次向外折射,经过两次向外折射后使得光源模组100的光照角度被加大。由于光源模组100的光照角度被加大,因此,在光源基板2的中间位置未安装发光单元3的情况下,也能使照明灯具中间区域具有一定的亮度。相对于现有技术,在保持照明灯具原有亮度的情况下,光源模组100内的承载发光单元3的光源基板2的尺寸可以缩小,发光单元3的数量也可以减少,从而降低了光源模组100的制造成本。另外,由于驱动电源可以安装于光源模组100的光源基板2上并收容于透镜1的收容槽1211内,使得光源模组100的基板2的空间得到充分利用,这样,包括了驱动电源的光源模组100就可以作为一个模块而组装至照明灯具的壳体内。另外,由于光源模组100通过磁性安装元件15即可牢固的吸附在吸顶灯上,安装方便,连接可靠。同时,光源模组100上的透镜1也作为电气绝缘壳体,提高了安全等级。It should be noted that the light source module 100 can be applied to a lighting fixture (not shown), such as a ceiling lamp. After the illumination lamp is activated, the light emitted by the light-emitting unit 3 in the light source module 100 passes through the light incident surface 112 of the edge portion 11 of the lens 1 and then undergoes an outward refracting.
The line extends in a straight line in the edge portion 11 of the lens 1. When the light reaches the light exit surface 113, a second outward refracting occurs. After two outward refracting, the illumination angle of the light source module 100 is increased. Since the illumination angle of the light source module 100 is increased, even when the light-emitting unit 3 is not installed at the intermediate position of the light source substrate 2, the illumination lamp intermediate region can have a certain brightness. Compared with the prior art, in the case of maintaining the original brightness of the lighting fixture, the size of the light source substrate 2 carrying the light-emitting unit 3 in the light source module 100 can be reduced, and the number of the light-emitting units 3 can also be reduced, thereby reducing the light source mode. The manufacturing cost of group 100. In addition, since the driving power source can be mounted on the light source substrate 2 of the light source module 100 and housed in the receiving groove 1211 of the lens 1 , the space of the substrate 2 of the light source module 100 is fully utilized, and thus the light source including the driving power source is included. The module 100 can be assembled as a module into the housing of the lighting fixture. In addition, since the light source module 100 can be firmly adsorbed on the ceiling lamp through the magnetic mounting component 15, the installation is convenient and the connection is reliable. At the same time, the lens 1 on the light source module 100 also serves as an electrically insulating housing, which improves the safety level.
结合图11所示,光源模组100b包括发光组件(未标号),发光组件包括至少两组发光单元,这几组发光单元是相互并联的,即各组发光单元均具有独立的支路,并且每组发光单元的数量可以相同也可以不同,仅需保证同组发光单元的色温相同,不同组发光单元的色温不同即可。As shown in FIG. 11, the light source module 100b includes a light-emitting component (not labeled), and the light-emitting component includes at least two groups of light-emitting units that are connected in parallel with each other, that is, each group of light-emitting units have independent branches, and The number of each group of light-emitting units may be the same or different, and only the color temperature of the same group of light-emitting units is required to be the same, and the color temperatures of different groups of light-emitting units may be different.
在本发明实施例中,这几组发光组件可被择一点亮或同时点亮,并且无论发光组件的点亮状态是什么,光源模组100b在配光元件(未图示)的配合下,发出的光线的亮度差总在预设差值范围内。In the embodiment of the present invention, the groups of the light-emitting components can be selectively lit or illuminated at the same time, and the light source module 100b is matched by the light-distributing component (not shown) regardless of the lighting state of the light-emitting component. The difference in brightness of the emitted light is always within the preset difference.
这个预设差值范围可以根据照明场景预设,例如对亮度要求不是很高的照明场景,可以适应性增大预设差值范围,以使得光源模组100b的亮度差不会过大,用户不会感觉到光线的光强有变化,从而避免了人眼观感上的不适。The preset difference range may be preset according to the illumination scene, for example, a lighting scene that is not very high in brightness requirement, and the preset difference range may be adaptively increased, so that the brightness difference of the light source module 100b is not excessive, the user It does not feel the change in the light intensity of the light, thus avoiding the discomfort of the human eye.
在本发明实施例中,预设差值范围是10%至15%,例如可以是15%、10%或其他数值,例如光源模组100b在配光元件(未图示)的配合下,发出的光线的亮度差为变化前亮度值的15%。后续,各组发光单元在并联后与驱动电源组件4b串联,以从驱动电源组件4b获取工作所需电流。In the embodiment of the present invention, the preset difference range is 10% to 15%, for example, may be 15%, 10% or other values. For example, the light source module 100b is issued by a light distribution component (not shown). The difference in brightness of the light is 15% of the brightness value before the change. Subsequently, each group of light-emitting units is connected in series with the driving power source unit 4b in parallel to obtain a current required for operation from the driving power source unit 4b.
在实际应用中,各组发光单元位于同一段光源基板上,也可以位于不同的光源基板上。在本发明实施例三中,每段光源基板上只承载
