Abstract

The utility model discloses an LED illumination system. The system comprises an LED driving power supply and a plurality of LED lamps. The LED driving power supply and the lamps are arranged independently. Each lamp is respectively and independently connected with the LED driving power supply. The LED driving power supply and the lamps are independently designed, parts disposed inside each lamp is minimized, each lamp has a simple structure, and the power supply is not arranged inside the lamp, thereby minimizing heating and improving the LED luminous efficiency. The LED driving power supply serves as an independent power supply, so that the performance of the power supply is favorably improved and costs are lowered. Moreover, interference by the driving power supply to an electrical network is minimized, and an influence of electromagnetic radiation upon an environment is minimized.

Description

The LED illuminator

Technical field

The utility model belongs to lighting field, particularly relates to the LED lighting field.

Background technology

The LED illumination is widely used owing to its energy-conserving and environment-protective gradually; The common LED lamp tool all uses the mode of a lamp one power drives; Be about to the LED light fixture with and driving power do together or installed adjacent; This mounting means makes power supply generate heat with LED, and the temperature of light fixture is raise, and can reduce the luminous efficiency of LED; Because the driving of LED need convert civil power into the low pressure constant-current supply, its Switching Power Supply operating frequency is higher, to producing electromagnetic interference on every side in addition; There is a power drives of use such as LED to increase the cost of power supply again.

Summary of the invention

To above-mentioned the problems of the prior art of mentioning, the utility model provides a kind of driving power and the light fixture LED illuminator of installation and design respectively.

This system comprises a LED driving power and several LED light fixtures, and described LED driving power and light fixture are independently installed, and each light fixture is installed in diverse location respectively.

Described each light fixture independently is connected respectively with said LED driving power separately.

Described light fixture is connected with described LED driving power after can also connecting each other again.

Described light fixture is connected with described LED driving power after can also be parallel with one another again.

The driving power of said LED illuminator is a public direct-current power supply that power is bigger.

The driving power of said LED illuminator comprises the EMI circuit, input rectifying, filter circuit, power conversion circuit, output rectification, filter circuit, PWM controller, PFC unit and multichannel output control circuit.

The driving power of said LED illuminator also comprises lightning protection unit, imports under-voltage and/or Overvoltage protecting unit, output current limiting and/or Overvoltage protecting unit.

The driving power of said LED illuminator has a shell that prevents electromagnetic radiation.

The driving power and the light fixture of the LED illuminator that the utility model provides are installed respectively; Except that the LED light-emitting diode, contain in the light fixture seldom even do not contain other electron component; Its structural design is comparatively simple, for the space has been reserved in designs such as the reliability of light fixture, fail safe, useful life, and non-transformer in the light fixture and reduced caloric value temperature rise is reduced; Can improve the luminous efficiency of LED, also can do the variation of multiple shape and structure; Because the big driving power of the shared power of a plurality of light fixtures; The little driving power cost of power is few with respect to using separately respectively; More help driving power is optimized design, make driving power little to the influence of electrical network, efficient improves; Can also take shielding measure to driving power, reduce positive effects such as electromagnetic radiation.

Embodiment

Present embodiment is the utility model preferred implementation, and other all its principles are identical with present embodiment or approximate with basic structure, all within the utility model protection range.

Please referring to accompanying drawing 1, use a driving power in the system of the utility model LED illumination, it can be according to various demand; Be designed to multichannel output, external light fixture of each road output, circuit theory such as Fig. 2 in each light fixture; Shown in this figure in the light fixture a plurality of LED lamp pearls series connection back in parallel connection; Certainly, light fixture schematic diagram shown in Figure 2 is not the novel unique pattern of this use, and it is appreciated that to having only a plurality of lamp pearls simply to connect; Can also be series connection again after each LED lamp pearl parallel connection, and be their combination in any series-parallel connection or simple parallel connection.

Another embodiment of the utility model is to use a drive power supply, and a plurality of light fixture series connection back is connected with this driving power, and light fixture can be installed in diverse location respectively.

The novel embodiment again of this use is to use a drive power supply, be connected on this driving power after a plurality of light fixture parallel connections, light fixture can be respectively according at diverse location.

In schematic diagram shown in Figure 2, the actual conditions when all right foundation designs add that in the line some are simple like current-limiting resistance, devices such as voltage-stabiliser tube, and the adding of these devices is for the design of optimizing driving power and light fixture or use.

Fig. 3 is the typical power supply block diagram of the utility model LED illuminator, but driving power is not limited thereto, and can be general on the market dc constant flowing power; Also can be custom-designed constant-current supply, in the present embodiment, driving power be by the EMI circuit; Input rectifying, filter circuit, power conversion circuit, output rectification, filter circuit; And PWM controller and PFC unit composition, wherein power conversion circuit is to convert direct current into the dither direct current through switching circuit.

All right some auxiliary circuit in the driving power; Input as at power supply connects lightning protection unit; Make it certain protective action arranged, input overvoltage and/or under-voltage protection unit can also be set, in the rear end of driving power to the surge current/voltage on the circuit; Output current limiting and/or Overvoltage protecting unit can be set, circuit such as short-circuit protection unit.

Because the operating frequency of Switching Power Supply is higher, produce the electromagnetic radiation surrounding environment, can the metallic shield shell be set to driving power, reduce electromagnetic interference to the outside.

The LED illuminator of the utility model; With driving power and independent respectively setting of light fixture and installation; Very big flexibility all is provided for the design of power supply and light fixture, transmission is direct current from the power supply to the lamp locker, under identical through-put power situation; The sectional area of transfer wire capable of reducing using reduces cost.

The LED illuminator of the utility model can be used in places such as factory, office buildings, market, public place and family widely.
