Lamp control circuit and lamp using same

Abstract

The invention discloses a lamp control circuit and a lamp using the same. The lamp comprises a power supply module used for providing power and the lamp control circuit. The power supply module comprises a primary control circuit and a secondary main control circuit which is electrically connected with the primary control circuit. The lamp control circuit is electrically connected to the secondary main control circuit, and comprises a secondary auxiliary control circuit module, a secondary filtering circuit module and a secondary control signal input module. The secondary filtering circuit module is used for restraining common-mode signals coupled to the lamp control circuit from the power supply module. According to the lamp control circuit and the lamp using the same, the secondary filtering circuit module used for restraining the common-mode signals is arranged between the secondary auxiliary control circuit module and the secondary control signal input module, so that the lamp control circuit serving as a control end can pass electromagnetic interference tests and further prevent the operation of other electrical appliances in the whole circuit such as televisions and radios from being interfered.

Description

technical field [0001] The invention relates to a lighting device, in particular to a lamp control circuit and a lamp using the lamp control circuit. Background technique [0002] In general daily life, various lighting devices can be seen everywhere, for example, fluorescent lamps, street lamps, table lamps, art lamps and the like. Among the above-mentioned lighting devices, traditionally, most of them use tungsten filament bulbs as light sources. In recent years, light-emitting diodes (LEDs) have been used as a source of light due to advances in technology. What's more, in addition to lighting equipment, for general traffic signs, billboards, car lights, etc., light-emitting diodes are also used as light sources instead. As mentioned above, the advantage of using light-emitting diodes as a light source is that it saves power and has higher brightness, so it has gradually become popular in use. [0003] With the popularization of LED lamps, LED lamps are used in more and...

Problems solved by technology

In addition, as people's living needs change, they are no longer satisfied with the single brightness, color, and color temperature light emitted by LED lamps. Therefore, it is necessary to add a control input circuit to the circuit of LED lamps to adjust the LED in time according to user needs. The characteristic parameters of the light emitted by the lamp
