Description
Technical field
The utility model relates to LED daylight lamp, specifically, is a kind of civil power direct-furnish LED daylight lamp directly can replacing fluorescent lamp.
Background technology
The places such as existing public place, school, enterprise, 90% adopts traditional fluorescent lamp, its internal circuit as shown in Figure 1, containing ballast 1, jump bubble 2, fluorescent tube 3, lamp switch 4, input voltage 220V alternating current.
Fluorescent tube is equipped with two filaments, filament scribbles electronic emission material triplex carbonate (brium carbonate, strontium carbonate and calcium carbonate), is commonly called as electronic powder.Under alternating voltage effect, filament is alternately as negative electrode and anode, and tube inner wall scribbles fluorescent material, is filled with the argon gas of 400Pa-500Pa pressure and a small amount of mercury in pipe.After energising, liquid mercury flashes to the mercury vapour that pressure is 0.8 Pa, under electric field action, mercury atom is constantly provoked into excitation state from reset condition, then spontaneous transition is to ground state, and (main peak wavelength is 253.7nm, accounts for the 70-80% of whole radiant energy to give off the ultraviolet of wavelength 253.7nm and 185nm; Minor peaks wavelength is 185nm, accounts for 10% of whole radiant energy), to discharge unnecessary energy.Fluorescent material sends visible ray after absorbing ultraviolet radiant energy.Fluorescent material is different, and the light sent is also different.
Containing a large amount of mercury vapors (mercury vapour) in traditional fluorescent lamp (fluorescent lamp), if fluorescent tube is broken, mercury vapor (mercury vapour) then can evaporate in air, pollutes.Traditional daylight lamp fixture can produce a large amount of heat energy, and light efficiency is lower.During the work such as ballast, jump bubble, noise can be produced.Traditional fluorescent lamp uses alternating current, so each second can produce the stroboscopic of 100-120 time, has infringement to the eyes of people.Traditional fluorescent lamp can send ultraviolet etc., has a lot of mosquito to be centered around by lamp source.
Summary of the invention
The purpose of this utility model is to provide one and realizes civil power and directly power, easy for installation, power cost saving, low cost, long-life civil power direct-furnish LED daylight lamp directly can replacing fluorescent lamp.
The civil power direct-furnish LED daylight lamp directly can replacing fluorescent lamp described in the utility model, it comprises the circuit that two ends can directly be connected with alternating current, the bidirectional constant circuit that described circuit comprises at least one LED lamp, connects with LED lamp, described bidirectional constant circuit comprises two branch roads in parallel, branch road is in series with rectifier diode and current regulator diode.
The utility model adopts the bidirectional constant circuit of two rectifier diodes and current regulator diode composition, Direct driver AC LED (two-way LED).Adopt bidirectional constant circuit, have structure simple, constant output current, carrying load ability is strong, safe and efficient.
The above-mentioned civil power direct-furnish LED daylight lamp directly can replacing fluorescent lamp, branch road is also in series with resistance.Electric current can be regulated by resistance.
The above-mentioned civil power direct-furnish LED daylight lamp directly can replacing fluorescent lamp, the joint that the two ends of described circuit are connected with alternating current adopts G13 type joint.Described circuit is positioned at a fluorescent tube, and G13 type joint is fixed at the two ends of fluorescent tube.G13 type joint is adopted conveniently to be connected with the lamp socket of existing installation fluorescent lamp.
The beneficial effects of the utility model:
1. environmental protection.But LED daylight lamp does not then use mercury, and LED product is not leaded yet, plays a protective role to environment.
2. heating is few.LED lamp is then that electric energy is all converted to luminous energy, can not cause the waste of the energy.And also can not produce discoloring effect to file, clothing.
3. there is no noise.LED lamp can not produce noise, and the occasion for use precision electronic device is excellent choosing, is suitable for library, the occasion of office and so on.
4. protect eyes.LED daylight lamp adopts LED constant current work, is alternating current direct is switched through be changed to direct current, effectively reduces LED light and declines, and starts fast, flicker free, protection eyes.
5. worried without mosquito.LED daylight lamp can not produce the radiation such as ultraviolet light, infrared light, to become more that clean hygiene is clean and tidy without mosquito around, indoor.
6. the scope of supply voltage is large, is generally 80V-245V.Traditional fluorescent lamp is that the high voltage discharged by rectifier is lighted, and then cannot light as the voltage decreases.And LED lamp can be lighted within the voltage of certain limit, brightness can also be adjusted.
7. province's electric life is long.The power consumption of LED daylight lamp is less than 1/3rd of traditional fluorescent lamp, and the life-span is also 10 times of traditional fluorescent lamp, basically identical with traditional fluorescent lamp brightness, normal service life is more than 30,000 hours, economize on electricity up to 50%, can Long-Time Service and without the need to change, reduce labour cost.Be more suitable for the occasion being difficult to change.
8. firm firm.LED lamp itself use epoxy resin and and unconventional glass, firmer firm, also can not damage easily at ground onboard led even if pound, can use relievedly.
9. versatility is good.Install the utility model of fluorescent tube, G13 type joint additional, external form, size are the same with traditional fluorescent lamp, alternative conventional lamp.
10. rich color.Make full use of the LED lamp that the coloury advantage of LED makes various glow color.
