The invention provides a light-emitting module. The light-emitting module comprises a plurality of light-emitting chips, an aluminum substrate and a copper-clad layer covering the surface of the aluminum substrate, wherein two opposite surfaces of the aluminum substrate are a first surface and a second surface respectively, the copper-clad layer forms a first circuit on the first surface of the aluminum substrate, the copper-clad layer forms a second circuit on the second surface of the aluminum substrate, and the first circuit and the second circuit are arranged in parallel; and any one of the plurality of light-emitting chips is arranged on the first circuit or the second circuit in a bonding manner. According to the light-emitting module, through the structural improvement of the light-emitting module, the dimming controllability of the light-emitting chip is improved.
Description
technical field [0001] The invention relates to the field of lamps, in particular to a light-emitting module and a lamp. Background technique [0002] figure 1 A schematic diagram of the circuit principle structure of the existing lamp is shown. After the mains power is converted into direct current through a transformer, the unidirectional diode is used to supply power to the light-emitting module, and a switch tube is connected between the unidirectional diode and the negative pole of the light-emitting module, and then the switch tube is controlled by the dimming unit. The light emitting module performs dimming. [0003] Specifically, for the composition of the light-emitting module, when an aluminum substrate is used, copper is usually coated on the surface of the aluminum substrate to form a circuit for bonding the light-emitting chip. In actual implementation, a gap is formed between the copper-clad layer and the aluminum substrate. Distributed capacitance, when the...
