One end fluorescent lamp refers to the single lamp holder low voltage mercury-vapour discharge lamp, and its major part is only emitted by the UV-activated fluorescent coating of discharge generation.Can from light fixture, disassemble, be used among the custom-designed light fixture, by with the incorporated control circuit of light fixture, reach the purpose of design of decorating or optimizing illumination functions.Lamp holder has two kinds on two pins (2P) and four pins (4P), contains starter (also claiming to jump bubble) and anti-interference capacitor in the lamp holder of two pins, and has no the circuit elements device in the lamp holder of four pins.

The present stage electric energy ten minutes instability that causes voltage in short supply, under unsettled voltage, present electricity-saving lamp can not give out stable light, forms " stroboscopic radiation ", and long-term user's eyes are damaged.

Summary of the invention

For solving the technical problem of above-mentioned existence, the utility model provides a kind of novel energy-conserving lamp, can reduce the stroboscopic radiation, regulates glow frequency automatically according to varying environment and light, thereby accomplishes to give out the light of appropriateness, reduces the injury to user's eyes.

For achieving the above object, the technical scheme that the utility model adopts is following:

A kind of novel energy-conserving lamp; Include fluorescent tube and lamp holder, said the inner surface of tube is coated with rare-earth trichromatic fluorescent powder, and said lamp holder set inside has electric ballast; Said electric ballast includes resistance R 1-R2, diode VD1-VD5, capacitor C 1-C3, transistor VT1-VT2, transformer T1a-T1b; Said diode VD1-VD4 forms rectifier bridge, and resistance R 1 is connected the back in order to connect the two ends of 220V power supply with rectifier bridge, and resistance R 2 is connected the back with capacitor C 1 parallelly connected with the other two ends of rectifier bridge; The emitter-base bandgap grading of said transistor T 1a is connected with the collector electrode of transistor T 1b; Said capacitor C 2 and capacitor C 3 series connection, said transistor T 1a and T1b, capacitor C 2 and C3 all with ground connection after the other two ends of rectifier bridge are parallelly connected, transformer T1a two ends are connected with emitter-base bandgap grading with the base stage of transistor VT1 respectively; Transformer T1b two ends are connected with emitter-base bandgap grading with the base stage of transistor VT2 respectively, the base stage that the end of said diode VD5 is connected between resistance R 2 and the capacitor C 1, the other end is connected in transistor VT2.

The utility model utilizes novel electron ballast output stablizing high frequency voltage, improves light efficiency, is fit to various voltage environment, reduces the stroboscopic radiation; Adopt rare-earth trichromatic fluorescent powder as the internal illumination material, illuminant colour originality is good, presses close to the receptible light of people, at utmost reduces the injury of light to user's eyes.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:

As depicted in figs. 1 and 2 is a specific embodiment of the utility model, includes fluorescent tube 1 and lamp holder 2, and said fluorescent tube 1 inner surface is coated with rare-earth trichromatic fluorescent powder; Can largely improve luminous efficiency; And can reduce the extent of injury of light, make the light that gives out more can let eyes accept, and the light chromogen property of sending number to eyes; Can better restore original color; And can better highlight the bright-coloured degree of object color, make it the receptible light of properer people, give the pleasing sensation of people.Healthy eye health to long-term user is of great advantage.

Said lamp holder 2 set inside have electric ballast 3; Said electric ballast 3 includes resistance R 1-R2, diode VD1-VD5, capacitor C 1-C3, transistor VT1-VT2, transformer T1a-T1b; Said diode VD1-VD4 forms rectifier bridge; Resistance R 1 is connected the back in order to connect the two ends of 220V power supply with rectifier bridge; Parallelly connected with the other two ends of rectifier bridge after resistance R 2 is connected with capacitor C 1, the emitter-base bandgap grading of said transistor T 1a is connected with the collector electrode of transistor T 1b, said capacitor C 2 and capacitor C 3 series connection; Said transistor T 1a and T1b, capacitor C 2 and C3 all with ground connection after the other two ends of rectifier bridge are parallelly connected; Transformer T1a two ends are connected with emitter-base bandgap grading with the base stage of transistor VT1 respectively, and transformer T1b two ends are connected with emitter-base bandgap grading with the base stage of transistor VT2 respectively, the base stage that the end of said diode VD5 is connected between resistance R 2 and the capacitor C 1, the other end is connected in transistor VT2.
