Meanwhile, the cost of the power supply part is greatly reduced. The installation and debugging process of a power supply to be installed onto a lamp is also simplified, and the production capacity of the power supply part is improved.
Description
Technical field
The utility model relates to a kind of structure of power carrier communication control power supply.
Background technology
In the LED power supply; power carrier control is a kind of novel secondary energy-saving control power supply; but in design, usually can run into the problem that much interferes with each other; because the interference of employing itself; make carrier signal be difficult to demodulate clean signal; so can produce various misoperations, power supply can't be effectively controlled, so a lot of design engineer dare not partly combine carrier wave with power unit.With reference to shown in Figure 1, the structure of conventional electric power carrier communication control power supply all is carrier wave partly to be separated with power unit assemble usually, carry out communication by the cable connection between two kinds of different structures, adopt two problems that complete independent structures evades interfering with each other, but installation is cumbersome with production test, and has increased production cost.
So, problem at above-mentioned prior art existence, be necessary to study in fact, the integrative-structure of power supply is provided with the power carrier communication that provides carrier wave part and power unit to combine, have characteristics such as simple, easy to connect, that cost is low are installed, and can effectively solve switch high-frequency power supply interference problem.
Summary of the invention
For addressing the above problem, the integrative-structure of the power carrier communication control power supply that the purpose of this utility model is to provide carrier wave partly and power unit is combined, have characteristics such as simple, easy to connect, that cost is low are installed, and effectively solved switch high-frequency power supply interference problem.
For achieving the above object, the technical solution of the utility model is:
A kind of structure of power carrier communication control power supply, comprise shell, be provided with carrier wave part and power unit in its shell, carrier wave partly comprises carrier wave input and modulation, the amplification of carrier wave high frequency power, input and the light modulation processing that connects successively, and power unit comprises that the input and the EMI that connect successively suppress circuit, pfc circuit, half-bridge resonance reduction voltage circuit and constant current/light modulation drive circuit.
Further, described shell adopts aluminum, has heat radiation, shielding action.
Further, described carrier wave is partly isolated by copper number fin and power unit, and earth point thermally meets at high pressure, and while copper number fin is also as heat radiation and the shielding of power unit.
The structure of the utility model power carrier communication control power supply is compared with traditional structure, the carrier wave part is installed together with power unit, not only effectively solve switch high-frequency power supply interference problem, realized the signal integrity transmission, and greatly reduce the cost of power unit, simplify the power supply installation and debugging process on the light fixture, improved the production production capacity of power unit.
