Abstract

The utility model discloses a compatible illuminating lamp, which comprises a lamp body and a fluorescent lamp light source circuit arranged on the lamp body. The lamp body is further provided with an LED lamp light source circuit and a changeover switch, and the changeover switch enables the fluorescent lamp light source circuit and a fluorescent lamp to be connected to form an illuminating loop through changing over a connection point of a closed circuit, or enables the LED lamp light source circuit and an LED lamp to be connected to form the illuminating loop. The compatible illuminating lamp disclosed by the utility model can be compatible with the common fluorescent lamp tubes and the LED illuminating lamp tubes; when two lamp tubes are used alternately, the wiring is not altered necessarily, the switching in or the removal of an electronic ballast is not carried out necessarily; and only the position for changing over the switch accords with the switched-in illuminating lamp tube necessarily, so that the operation of replacing the lamp tubes of different types becomes simple and convenient, and the working time is saved.

Description

The Campatible lighting

Technical field

The utility model belongs to lighting and makes field, particularly a kind of Campatible lighting.

Background technology

Lighting is widely used in various places such as factories and miness, school, office, local-style dwelling houses, commercial building, hotel, illumination becomes the fundamental in our routine work, the studying and living, the most common use at present also the most widely lighting surely belong to fluorescent lamp, the incandescent lamp of comparing, be characterized in simple installation, life-span is long, and light is soft, and brightness is high.

Respectively there is a filament at the fluorescent lamp two ends, are filled with the argon of trace and thin mercury vapour in the fluorescent tube, scribble phosphor powder on the tube inner wall, send ultraviolet ray during gaseous conduction between two filaments, make phosphor powder send soft visible light.Its work characteristics: need a high voltage when fluorescent tube begins to light, normally only allow by little electric current when luminous, at this moment the voltage of lamp tube ends is lower than supply voltage.

Generally comprise Inductive ballast in traditional fluorescent lamp lighting circuit, electric elements such as starter, its operation principle is: after power connection, begin glow discharge between two electrodes of starter, make the bimetal leaf expanded by heating and contact with the stationary contact utmost point, so power supply, ballast, filament and starter constitute a closed-loop path, electric current makes filament pre-heating, as heated time 1-3 after second, two interelectrode glow discharges of starter are extinguished, disconnect with the stationary contact utmost point thereupon the bimetal leaf cooling, when the moment that two electrodes disconnect, the electric current in the circuit suddenly disappears, so ballast produces a high-voltage pulse, after the stack of it and power supply, be added to lamp tube ends, make the ionized inert gas in the fluorescent tube and cause arc discharge, in normal luminescence process, the self-induction of ballast also plays a part electric current in the stabilizing circuit.The defective of traditional fluorescent lamp except that consume non-ferrous metal too much, its loss to electric energy also can not be ignored.The resistance loss of Inductive ballast winding and the eddy-current loss of iron core are bigger, account for about 15% of lamp power loss.In addition, the power factor of Inductive ballast is lower, is generally about 0.5, can cause the severe contamination of electrical network, and power department has to strengthen power factor compensation capacitance, has increased power cost.

Fluorescent lamp has adopted follow-on electric ballast at present, and its operation principle is that power frequency (50Hz or 60Hz) power conversion is become 20～50KHz left and right sides high frequency electric source, directly lights a lamp, and need not other current limiting device.Compare with Inductive ballast, electric ballast has the following advantages: making the fluorescent tube light efficiency improve about 10%(than power frequency is the fluorescent tube of 4 chis by length), and oneself power consumption is low, it is about 20% that the total power input of lamp is descended, and better energy-saving effect is arranged; Eliminated stroboscopic, luminous more stable; Repeatedly starting point has been avoided in a starting point success behind the preheating fluorescent tube; The power factor height meets the above fluorescent lamp of 25W of national standard, and its power factor is higher than 0.95, but it should be noted that national standard is very high to the harmonic wave limit value of the regulation of the fluorescent tube below the 25W, drops to 0.7 ~ 0.8 to cause its power factor; Lamp tube service life is long; Noise is low etc.

Along with the progress of semiconductor technology, a kind of new LED illuminating lamp has been developed development, and begins to appear on the market.LED(Light Emitting Diode) being the english abbreviation of light emitting diode, is a kind of solid-state semiconductor devices, and it can directly be converted into luminous energy to electric energy.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole, and the other end is the positive pole that connects power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of three parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics here, the middle normally SQW in 1 to 5 cycle.When electric current acted on this wafer by lead, electronics and hole will be pushed to SQW, and electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in SQW.And the light wavelength color of light just is by the material decision that forms the P-N knot.

Compare the fluorescent lamp of electric ballast, the LED lighting has following advantage: low in energy consumption, be about about 20% of electric ballast fluorescent lamp power consumption; Life-span is long, and the life-span of LED lamp reaches 50,000-80,000 hours, is about more than 10 times of fluorescent lifetime; Need not starter and ballast; The crevice projection angle adjustable range is big, good directionality; Light is soft, and spectroscopic pure helps people's sight protectio and healthy; Can adapt to explosive, wait adverse circumstances under water.Because the production scale of present domestic LED illuminating lamp is little, cost is higher, makes its price be higher than fluorescent lamp, but along with national green energy conservation illuminating engineering focus development, and the progress of science and technology, its manufacturing cost can reduce gradually, alleviates inferior position on the high side.Ultra-high brightness LED might become a kind of very competitive new type electro source.

Because the LED volume is little, the LED illuminating lamp can be encapsulated as common fluorescent lamp shape, can use original fluorescent lamp lighting light fixture, original fluorescent lamp can be taken off during installation and change the LED illuminating lamp, need to change wiring simultaneously, elements such as ballast are removed, the 220V AC power directly is added to LED illuminating lamp two ends.At present because LED illuminating lamp price is higher, marketing network seldom in case damage, can't in time be changed, and will have a strong impact on work and life, needs corresponding illuminating lamp spare unit, if with identical LED illuminating lamp as spare unit, then produce higher spare unit cost.A kind of method of accommodation is as spare unit, will reduce the spare unit cost with common fluorescent lamp like this, but the weak point of this method to be: want rewiring when changing spare unit, and insert element such as ballast again, make the complexity that more changes jobs, and expend man-hour.
