Description
Technical field
The utility model relates to a kind of LED fluorescent lamp, belongs to the LED applied technical field.
Background technology
The described fluorescent lamp of tradition claims again fluorescent lamp.Appearance is fine, and is long.Respectively there is a filament at the fluorescent lamp two ends, are filled with the argon of trace and thin mercury vapour in fluorescent tube, scribble fluorescent material on tube inner wall, send ultraviolet ray during gaseous conduction between two filaments, make fluorescent material send soft visible light.The wattage of its ballast must on an equal basis just can support the use with the wattage of fluorescent tube, otherwise can affect startability, photoelectric parameter and the service life of fluorescent tube.Fluorescent lamp can not frequent starting, every startup once, lamp tube service life can shorten two hours.The temperature and humidity of environment for use is suitable, and the optimum environment temperature is 18 ℃-25 ℃, and relative humidity more easily starts when 50% left and right.Mode of connection is wanted accurately.Step-down comes light modulation to desk lamp with dimmer switch by resistance, because the loss of dropping resistor, so that the lamp of identical brightness take than incandescent lamp is electric, equally usually should not make room lighting with the lamp of degree of lightening.
Contain a large amount of mercury vapours in traditional fluorescent lamp, if broken mercury vapour can evaporate in atmosphere.But the LED fluorescent lamp does not use mercury, and the LED product is not leaded yet, and environment is played a protective role.The LED fluorescent lamp is known as the green illumination of 21st century.The LED fluorescent lamp can efficiently be changed, and reduces heating, and conventional lamp can produce a large amount of heat energy, and the LED light fixture is that electric energy fully is changed to luminous energy, can not cause the waste of the energy.
The relatively common fluorescent lamp of LED fluorescent lamp can not produce noise, is excellent choosing for the occasion of using precision electronic device.Be suitable for the library, the occasion of office and so on.What traditional fluorescent lamp used is alternating current, so can produce the stroboscopic of 100-120 time each second.The LED fluorescent lamp is alternating current direct to be switched through be changed to direct current, can not produce scintillation, the protection eyes.The LED light fixture can not produce ultraviolet ray, therefore can be as traditional light fixture, and there are a lot of mosquitoes to be centered around by the lamp source.Indoor meeting becomes, and clean hygiene is clean and tidy more.Traditional fluorescent lamp is to light by the high voltage that rectifier discharges, and can't light when lower voltage.And the LED light fixture can be lighted within the voltage of certain limit, can also adjust brightness. the power consumption of LED fluorescent lamp is below 1/3rd of traditional fluorescent lamp, life-span is also 10 times of traditional fluorescent lamp, can use for a long time and need not to change, and reduces labour cost.Be more suitable in the occasion that is difficult to change.LED lamp body itself uses be epoxy resin and and unconventional glass, firmer firm, also can not damage easily at the ground onboard led even pound, can use relievedly.Compare with common fluorescent lamp, the LED fluorescent lamp need not ballast, need not starter, without stroboscopic, non-maintaining, frequent switch can not cause any damage, safety and stable quality is arranged, can stand that 4kv high voltage heat dissipation capacity is low can be operated in 55 ℃ of low temperature-30 ℃ high temperature, freedom from vibration is good, is convenient to transportation.
The LED fluorescent lamp has begun be used to replacing existing common fluorescent lamp, and the LED fluorescent lamp is more and more universal in utilizations such as commodity show windows, but only 180 ° of LED fluorescent lamp lighting angles in the market, wide-angle more not, and how to improve the light emission rate of LED fluorescent lamp and go out light effect be that the LED industry is studying a question always.
Summary of the invention
LED fluorescent lamp of the present utility model comprises built-in power, PC cover, light source, PCB lamp plate, lens, be used for placing built-in power and fixedly hollow tubular type aluminium section bar, the plug of PCB lamp plate, wherein the cross section curvature of PC cover greater than 180 ° less than 360 °, the PC cover links with hollow tubular type aluminium section bar hasp, consist of the ellipse long tube, by the fixing long tube two ends of plug.Increase the rising angle of LED daylight by the curvature that increases the PC cover, and design PC cover links as shown in Figure 1 with hollow tubular type aluminium section bar hasp, be convenient to the maintenance of follow-up LED fluorescent lamp.
The hollow part of the hollow tubular type aluminium section bar of LED fluorescent lamp of the present utility model is used for placing power supply, hollow tubular type aluminium section bar cross section is isosceles trapezoid, its bottom is that arc and PC cover consist of ellipse, and the PCB lamp plate is fixed on the aluminium section bar upper base, and light source is positioned on the PCB lamp plate.
The light source of LED fluorescent lamp of the present utility model is LED SMD lamp pearl.
Go out uniformity of light for improving light source, the light source led SMD lamp pearl of LED fluorescent lamp of the present utility model is preferably double parallel and is stagger arrangement and arranges.
It is 3mm-4mm that the light source led SMD lamp pearl of LED fluorescent lamp of the present utility model is the distance that stagger arrangement arranges between its double LED SMD lamp pearl, with between before and after the bank light pearl apart from 5mm-8mm.
The light source led SMD lamp pearl of LED fluorescent lamp of the present utility model is the distance that stagger arrangement arranges between its double LED SMD lamp pearl and is preferably 3.5mm, with the preferred 7mm of distance between before and after the bank light pearl.
For improving the light emission rate of LED fluorescent lamp, having added lens in the utility model on light source is fixed on hollow tubular type aluminium section bar upper base, be positioned on PCB lamp plate and light source, the lens cross section is isosceles triangle, two waists of the cross section of hollow tubular type aluminium section bar respectively with two limits of lens on same straight line.Two waists of the cross section by aluminium section bar guarantee LED fluorescent lamp no dark space with two limits of lens respectively on same straight line.
The height of the utility model preferred lens cross section is the isosceles triangle of 11.0mm, and the close to sources place is the wide 12.0mm that is, height is that the circular arc type of 3.59mm caves in.
It is the T8 fluorescent tube that technological selection of the present utility model is used for fluorescent lamp, and the long diameter of the ellipse of ellipse long tube is 30.0mm.
The artificial light emission rate that further improves the LED fluorescent lamp of invention of the present utility model, lens distance light source surface design becomes to be made of numerous little convex lens, the preferred diamond surface shape of little convex lens.The light scioptics evenly scatter to the lampshade surface, the less convex lens that see through lens surface further spread, and reach fluorescent tube both sides bright dipping without the dead angle no dark space.
