Abstract
The utility model discloses a long-distance transmitting low-voltage halogen lamp, consisting of an electronic transformer and an electric light source. The electronic transformer includes a rectification circuit, a flip-flop circuit, a power output circuit and a step-down coupling circuit, the electronic transformer is also provided with a high-frequency rectification circuit which is connected with the step-down coupling circuit. The high-frequency rectification circuit comprises a Schottky common cathode half-bridge V1, and because the high-frequency rectification circuit is positioned in the electronic transformer, the high frequency electricity output by an ordinary electronic transformer is changed into unidirectional pulsated low-tension direct current, which solves resistance in long distance transmission for the purpose of achieving remote transmission.
Description
Technical field
The utility model relates to a kind of Halogen lamp LED, especially a kind of low pressure halogen lamp of remote transmission.
Background technology
The low pressure halogen light fixture has advantages such as light efficiency height, light quality be good.It generally comprises electronic transformer and electric light source, and electronic transformer comprises rectification circuit, circuits for triggering, power output and step-down coupling circuit.Electronic transformer converts civil power the low tension of high frequency to, and its frequency is generally at 25-38KHZ, and voltage is 12V, 18V or 24V, and electric light source is given in power supply, makes light source luminescent.The electronic transformer of general halogen etc. and the distance of electric light source are closer, are no more than 5 meters as the distance of halogen Down lamp electronic transformer and electric light source.Then, for some special occasions, the required distance of electronic transformer and electric light source is distant, as the safety for the assurance swimming pool, electric wire under swimming pool or on every side need adopt safe low-voltage, and at this moment the distance of electronic transformer and electric light source generally reaches about 100 meters, as the electric frequency that adopts the output of common electronic transformer is at 25-38KHZ, at this moment remote lead plays the effect of inductance, and the voltage of electronic transformer output is hindered on lead, and electric light source can not be worked.From finding the experiment that repeatedly when the distance of electronic transformer and electric light source surpassed 15 meters, the luminous meeting of electric light source obviously weakened.
Summary of the invention
At the problems referred to above, the problem that the utility model quasi-solution is determined is that electronic transformer can be transported to electric light source with electricity at a distance, and a kind of low pressure halogen lamp of remote transmission promptly is provided.
For addressing the above problem, the utility model is by the following technical solutions: a kind of low pressure halogen lamp of remote transmission, it comprises electronic transformer and electric light source, described electronic transformer comprises rectification circuit, circuits for triggering, power output circuit and step-down coupling circuit, also organized high-frequency rectification circuit in the described electronic transformer, described high-frequency rectification circuit and step-down coupling circuit are electrically connected.
Described high-frequency rectification circuit comprises Xiao Jite cloudy half-bridge V1 altogether, is total to cloudy half-bridge V1 by Ji Te the high-frequency electrical of step-down coupling circuit output is carried out rectification.
The low pressure halogen lamp of above-mentioned remote transmission, described high-frequency rectification circuit is electrically connected the electric output behind the step-down coupling circuit.
Because group has been gone into high-frequency rectification circuit in electronic transformer, make the high-frequency electrical of the output of ordinary electronic transformer change the low-voltage DC of unidirectional pulsation into, solve the impedance in long Distance Transmission, thereby reached the purpose of long-distance transmissions.
Description of drawings
Fig. 1 is the structural representation of the remote low pressure halogen lamp that transmits of the utility model.
Among the figure: the 1-electronic transformer, the 2-electric light source, the 3-rectification circuit, the 4-circuits for triggering, 5, power output, 6-step-down coupling circuit, the 7-high-frequency rectification circuit, 8-Xiao Jite is cloudy half-bridge V1 altogether.
Embodiment
Referring to Fig. 1: the low pressure halogen lamp of remote transmission of the present utility model, comprise electronic transformer 1 and electric light source 2, described electronic transformer 1 comprises rectification circuit 3, circuits for triggering 4, power output 5 and step-down coupling circuit 6, because said structure is identical with the electronic transformer of common Halogen lamp LED and Halogen lamp LED, do not describe in detail for saving length.
The high frequency voltage of the low pressure halogen electronic lamp transformer output of similar said structure, its frequency are generally at 25-38KHZ, and for indoor use, load (electric light source) generally is not more than 5 meters with the distance of electronic transformer, does not influence the brightness of light source substantially.When experiment showed, that distance when electric light source and electronic transformer is generally greater than 16 meters, the brightness of light source has only original 30%-50%, and is for the use of longer distance, nonsensical.Above-mentioned reason be since electronic transformer output be high frequency voltage, draw from induction reactance formula XL=2 π FL, induction reactance is directly proportional with frequency F, along with the distance increase of electric light source and electronic transformer, the output of electronic transformer is hindered in lead in a large number, thereby the power of electric light source be can not get.
In the electronic transformer of Halogen lamp LED far away of the present utility model in 1 also group gone into high-frequency rectification circuit 7.Described high-frequency rectification circuit 7 is electrically connected the electric output behind the step-down coupling circuit 6.Like this, make the high-frequency electrical of the output of ordinary electronic transformer change the low-voltage DC of unidirectional pulsation into, solved the impedance in long Distance Transmission, thereby reached the long-distance transmissions purpose.
The high-frequency rectification circuit 7 of present embodiment is to be total to cloudy half-bridge V1 by Xiao Jite to realize.Certainly the high-frequency rectification circuit of other form does not break away from protection range of the present utility model.
Adopt structure of the present utility model, only depend on the sectional area of delivery guidewire, general 8 squares of leads reach 100 meters, farther as need as long as increase sectional area of wire.
