Description
[technical field]
The present invention relates to frequency conversion rectifier equipment, relate in particular to a kind of power supply changeover device that is applied to Halogen lamp LED switching fluorescence and LED electricity-saving lamp.
[background technology]
It is little that many planes cold emission low pressure directional lighting lamp (being called for short cold shot-light) has a volume as a kind of novel energy-saving type interior illumination light source, luminous element is little, the high characteristics of light utilization efficiency when mixing corresponding reflective mirror, moreover it also adopts many planar mediums film reflective mirror, about 80% infrared ray sees through reflective mirror and is not projected onto on the photographed object, so the light beam temperature is low, face to be illuminated illumination is even, directionality is good, it is fresh-keeping to help commodity, it is true to nature and outstanding to develop the color, change catoptrical bandwidth of deielectric-coating and wavelength, can plate out red, yellow, green, the directional lighting effect that indigo plant etc. are colored is so its application is very extensive.
The light source of present cold shot-light has tungsten halogen lamp, fluorescent lamp and LED lamp, the LED light fixture has more energy-conservation than tungsten halogen lamp, longer service life, and its caloric value is lower, and the response time is shorter, the characteristics of environmentally safe, be subjected to more and more researchers' attention, along with the continuous development of semi-conductor industry, the LED lamp will be more and more universal as light source, development in recent years is especially rapid, and its alternative tungsten halogen lamp will become inexorable trend as the light source of cold shot-light.
What present power supply to low pressure directional lighting tungsten halogen lamp adopted is a kind of low pressure high-frequency electronic transformer, and the voltage of its out-put supply is 6V～24V, and operating frequency is 10K～40KHZ, and power is 4W～300W.And LED lamp when work adopt low pressure (DC power supply of 6V～24V), thus they two can not shared same power supply.
Fluorescent lamp (mainly referring to adopt the fluorescent lamp of electric ballast) has compact conformation, advantages such as volume is little, luminance is high, long service life, be widely adopted as electricity-saving lamp at present, as a kind of tungsten halogen lamp to the excessive electricity-saving lamp of LED lamp, it has the advantage that the LED lamp does not possess, for example cost is low, light is soft etc., so also still generally adopted the light source as cold shot-light in certain period.
Fluorescent lamp at low pressure (6V～24V) can pass through electronic inverter excitation fluorescent lamp operate as normal under the direct current supply state, so LED lamp and fluorescent lamp can shared power supplies.
The illumination shot-light tool that present average family generally adopts still is the cold shot-light of halogen tungsten, and popularizing along with energy-saving fluorescent lamp and LED electricity-saving lamp, a lot of families all need tungsten halogen lamp is replaced with fluorescence or LED electricity-saving lamp, and change the power supply part of light source when changing electricity-saving lamp again, it is the high-frequency electronic transformer, this high-frequency electronic transformer links to each other with the mains-supplied circuit, voltage is 110V～220V, so electrician if not specialty, very dangerous when changing power-supply device, if it is too high again to ask the professional to change the cost of labor of power-supply device, so need to adopt a kind of method and apparatus of replacing light fixture that can DIY.
In addition, if remove the cold shot-light power supply of original halogen tungsten part fully, change another power supply into, the power supply of then discarding also will cause very big pollution to environment, also increased simultaneously the cost of changing, so consider based on original power supply and power supply interface, only need to increase a kind of device and just can realize that the ordinary people also can change the purpose of lighting, has saved cost greatly.
[summary of the invention]
Purpose of the present invention is exactly in order to solve above-mentioned technical problem, the power supply changeover device that the spy provides a kind of tungsten halogen lamp to transfer fluorescence and LED electricity-saving lamp.
The interface of the cold shot-light of halogen tungsten has multiple at present; the more general GX that adopts international standards 5.3; its model also has multiple; more general employing be MR16; the present invention is that the cold shot-light of MR16 of GX5.3 is that example is introduced the technical solution adopted in the present invention with the interface; but can not be interpreted as at this point that protection scope of the present invention is confined to this kind interface, this kind model, the light fixture of this kind function.
Concrete technical scheme of the present invention is as follows:
A kind of power supply changeover device of tungsten halogen lamp switching electricity-saving lamp, described power supply changeover device comprises housing and circuit part, it is characterized in that, described housing comprises the input adapter with the corresponding connection of lamp socket, output plughole with the corresponding connection of lamp holder, described circuit part comprises converter unit and rectification unit, and the low pressure high-frequency alternating current flows out through output plughole from converting low-voltage DC to after input adapter is flowed through circuit part.
Described input adapter and output plughole are MR16 GX5.3 standard interface.
Described low pressure high-frequency alternating current converts the low pressure common frequencies to through converter unit, and (alternating current of 50HZ～60HZ) converts low-voltage DC to through rectification unit again.
The voltage of the alternating current of described low pressure high frequency is 6V～24V, and frequency is 10KHZ～40KHZ.
The power of described energy-saving fluorescent lamp or LED electricity-saving lamp is 4W～300W.
Described rectification unit comprises bridge rectifier diode.
Beneficial technical effects of the present invention is:
1. on the basis of original power supply and power supply interface, only need to increase power supply changeover device of the present invention, just can realize to tungsten halogen lamp to power-supply device to the power supply of energy-saving fluorescent lamp or LED electricity-saving lamp, need not the user and lose former power supply adaptor, for the user provides cost savings, also reduced environmental pollution simultaneously.
2. when changing power supply changeover device of the present invention, be based on the safe low-voltage of human body, so when changing power supply adaptor and changing light source, need not the electrician of specialty, common people is promptly replaceable, can save cost of labor greatly like this.
