The LED luminaire has simple structure, low cost, obvious effect, and is suitable for popularization and application.
Description
Technical field
The utility model relates to the LED light fixture that a kind of not polarity inserts power supply.
Background technology
Led light source have use low-tension supply, power consumption less, strong, the stability height of applicability, response time weak point, environmentally safe, multicolor luminous etc. advantage, though the existing illuminating equipment costliness of price still is considered to it and will substitutes existing illuminating device inevitably.
Though incandescent lamp that general lighting is used and halogen tungsten lamp low price, but light efficiency low (power consumption in vain of the fuel factor of lamp), life-span is short, maintenance workload is big, but if throw light on white light LEDs, not only light efficiency height, and life-span long (stream time is more than 10000 hours), Maintenance free almost, the urban traffic control lamp of China also just replace early stage traffic order indicator lamp with white light LEDs.Can predict in the near future, white light LEDs can enter family surely and replace existing illuminating lamp.
LED has polarity, if the power positive cathode at LED two ends is connect instead, LED just can not be luminous, burns out the danger of fluorescent tube simultaneously in addition, and external power supply formula LED fluorescent lamp is made up of lamp bracket, dc source, LED fluorescent tube at present.It in the LED fluorescent tube LED mount pad, the led array that the LED mount pad is made up of one or more LED, the simple connection of its circuit as shown in Figure 1, so the LED fluorescent-lamp tube when mounted, must be noted that the installation direction of polarity of LED fluorescent tube, therefore existing external power supply formula LED fluorescent tube has installs or changes inadequately shortcoming easily.
The utility model content
In view of this, the LED light fixture that the utility model provides a kind of not polarity to insert power supply can realize that the not polarity of LED mount pad inserts, and makes installation process simply light.
The purpose of this utility model provides the LED light fixture that a kind of not polarity inserts power supply, polarity does not insert the LED light fixture of power supply, comprise and be used to insert the incoming end I and the incoming end II of dc source and the LED lamp plate that is used to install LED lamp pearl, be provided with polarity switching between incoming end and the LED lamp plate, described polarity switching comprises diode D1, diode D2, diode D3 and diode D4, the negative pole of described diode D1 connects the positive pole of diode D2, the negative pole of described diode D2 connects the negative pole of diode D3, the positive pole of described diode D3 connects the negative pole of diode D4, the positive pole of described diode D4 connects the positive pole of diode D1, described incoming end I connects contact between diode D1 and the diode D2 or the contact between diode D3 and the diode D4, corresponding with it, described incoming end II connects contact between diode D3 and the diode D4 or the contact between diode D1 and the diode D2; The positive terminal of described LED lamp plate connects the contact between diode D2 and the diode D3, corresponding with it, the negative terminal of described LED lamp plate connects the contact between diode D1 and the diode D4.
Further, described polarity switching is IC chip DB157 or DB107.
The beneficial effects of the utility model are:
The utility model adds polarity switching by adopting in existing structure, can realize that the not polarity of LED light fixture inserts, and has shortened the set-up time, need not scruple unexpected generations the such as connecing the anti-ballistic fluorescent tube damage that causes because of polarity simultaneously; The utility model is simple in structure, cheap, effect is obvious, is fit to promote the use of.
