A dimming circuit and dimmable illuminating device are disclosed in the embodiments of the present invention, and relate to the technical field of illumination. The dimming circuit comprises an input unit, a segmented dimming unit and an output unit. The input unit is respectively connected with a power source and the segmented dimming unit and used for inputting voltage signals or current signals to the segmented dimming unit. The segmented dimming unit is further connected with the output unit and used for outputting the voltage signals or the current signals corresponding to different degrees of luminance to the output unit according to the operation of users. The output unit is used for outputting the received voltage signals or current signals corresponding to the different degrees of luminance to a light emitting device for driving the light emitting device to emit light. With the dimming circuit, the segmentation dimming of the lighting device can be achieved, and the glitter phenomenon caused by continuous current variation a can be avoided.
An LED stand is disclosed. The stand (6) comprises an opaque housing (7). A mounting surface (9) for holding at least one LED chip is arranged inside the housing (7). At least two light outlets (5) are arranged on the housing (7), so that the light emitted from the LED chip can be transmitted from the housing (7) through the at least two light outlets (5). The LED stand enables the LED which is assembled by the stand to be double-sided light-emitting, so that the emitting angle of the LED is increased, and the application scope of the LED is broadened. At the same time, because the LED stand enables the LED which is assembled by the LED stand to possess more light outlets, so that the number of reflection of light which is emitted by the LED chip mounted on the LED stand is reduced in the LED stand and the light extraction efficiency is greatly improved.
