Description
Technical field
The utility model relates to technical field of lighting fixtures, is a kind of LED illumination fluorescent lamp more specifically.
Background technology
LED is the abbreviation of English light emitting diode (light emitting diode), LED is a kind of semiconductor that electric energy can be converted into visible light, it has changed the luminous and energy-saving fluorescent lamp tricolor powder principle of luminosity of incandescent lamp tungsten filament, and adopt electric energy luminous, have long, numerous advantages such as light efficiency is high, radiationless, low-power consumption of life-span, along with the energy-conservation and proposition green illumination theory, LED is introduced in the lighting gradually as light source.
At present, the light emitting source that normal lighting lamps such as daily bulb, fluorescent lamp are adopted is based on incandescent lamp bulb or fluorescence fluorescent lamp basically, yet, the electro-optical efficiency of incandescent lamp bulb and fluorescence fluorescent lamp is all lower, and its heat is big, and service life is short, generally only has about 3000 hours.
LED then can overcome above shortcoming, and its internal characteristics has determined that it is optimal light source:
(1) volume is little.LED is that a very little wafer is encapsulated in epoxy resin the inside basically, thus its very little, very light.
(2) power consumption is low.The LED power consumption is very low, and in general the operating voltage of LED is 2-3.6V.Operating current is 0.02-0.03A.In other words: the electricity that it consumes is no more than 0.1W.
(3) long service life.Because what the LED lamp adopted is direct current supply, so under appropriate electric current and voltage, can reach 100,000 hours the service life of LED.
(4) environmental protection.LED is made by nontoxic material, and containing mercury unlike fluorescent lamp can pollute, and LED also can recycling simultaneously.
(5) sturdy and durable.LED is encapsulated in the epoxy resin the inside completely, and it is all firmer than bulb and fluorescence fluorescent lamp.Also do not have loosening part in the lamp body, it is non-damageable that these characteristics make that LED can be described as.
Wherein the LED fluorescent lamp is more extensive more than the scope of LED bulb application, especially in the family or in the office, the power supply of existing LED fluorescent lamp generally all is placed on body inside, make that narrow space was more crowded originally in the body, directly cause the heat radiation of LED obstructed, according to related data, the normal working temperature of LED is 50 ℃, if temperature has surpassed 55 ℃, the life-span of LED can reduce half, so this structure is very unreasonable.
There is the aluminium base of a lot of LED fluorescent lamps to be placed in the groove of radiator inwall again, because the aluminium base below is the cavity of radiator, the heat that makes LED produce can not effectively be transmitted on the radiator, and radiating effect reduces greatly, cause the interior temperature of fluorescent lamp too high, also can influence the life-span of LED; Also having the bottom of some fluorescent lamp heat radiation devices is flat, directly aluminium base is placed on the plane of radiator then, though doing the effect of heat radiation has like this reached, but since radiator make solid after, weight has but increased greatly, fluorescent lamp generally all need be hung on the roof, the requirement of weight also is very important, if overweightly will seem very heavy, also be easy to generate the danger of falling, cause personnel's injury.
And existing LED fluorescent lamp, the general chemical bonding agent that adopts is bonding between lamp holder and the body, this bonding agent is bonded at lamp holder on the body, though operation is simple, but the curing of bonding agent or drying, need the regular hour, so the equipped time of product is longer, stay simultaneously that the bonding agent in the slit is a kind of organic chemicals between lamp holder and the body, it can decompose lentamente or some chemical substances of dissociating corrode the body surface of plastic material, and produces color spot, strain line, aging phenomena such as crack significantly shorten the service life of product, and chemical bonding agent can produce niff, can injure the healthy of human body during use and environment is polluted.
Also have height that general fluorescent lamp aluminium base places also very arbitrarily, place the too high or too low phenomenon that black surround all can occur, thereby had a strong impact on the lighting quality of product.
The utility model content
In order to overcome above present difficulty, the purpose of this utility model is to provide a kind of rational in infrastructure, simple, well behaved LED fluorescent lamp of assembling.
The utility model takes following technical scheme to realize: a kind of LED fluorescent lamp, comprise lampshade, radiator, LED, aluminium base and lamp holder, described lampshade is connected with draw-in groove by raised line with described radiator, described LED is fixed on the described aluminium base, and be placed in the cavity between described lampshade and the described radiator, the vertical range in the described lampshade of the outward flange distance center of circle of described radiator is 1mm-3mm, the inside of described radiator also is provided with supporting plate, and it is the 4mm-10mm place that the position of described supporting plate is arranged on below, described lampshade center of circle vertical range.
The technical problem that the utility model solves can also take following technical scheme to realize:
The top of described supporting plate both sides is provided with press strip, and the distance between described press strip and the described supporting plate is slightly larger than the thickness of described aluminium base, and described aluminium base is placed between described supporting plate and the described press strip;
Also comprise lamp head shell, described lamp head shell and the corresponding position of described lamp holder are provided with trip, thereby form buckle structure, and both connect by buckle;
Described lamp holder is provided with through hole, the outer surface of described lamp holder is provided with two reeds, the outer surface of described lamp holder also is provided with retaining convex rib, the interior profile of described retaining convex rib and the outline of described reed are similar, also be provided with contact pin on the described lamp holder, described contact pin, reed and the riveted joint of described lamp holder;
One end of described aluminium base is welded with two leads, and described lead can be placed between described lamp holder and the described reed by described through hole, and described lead is pressed on the described lamp holder by described reed with screw;
Described radiator and the corresponding position of described lamp holder are provided with screw hole, and described lamp holder is fixed on the described radiator by screw.
The utility model advantage and beneficial effect are embodied in the following aspects:
1 the utility model is external with power supply, has thoroughly solved the narrow and small problem of lampshade intracavity space, has realized the maximization of LED heat radiation.
2 the utility model pass through the fixedly height of supporting plate, make the fixed-site of aluminium base, have solved the problem of illumination black surround fully.
3 lamp holders are connected with screw with radiator, make the product overall structure more firm, have increased shockproof properties.
The ratio of 4 lampshades increases, and the ratio of radiator reduces, and makes the lighting angle of product enlarge.
The both sides of 5 aluminium bases are fixed by press strip, have avoided because screw causes radiator charged after connecting electricity, and security improves greatly.
6 have increased the lamp head shell structure, and are connected with the lamp holder buckle, have avoided because all harm that viscose glue brings.
7 by increasing reed structure, makes assembly manipulation more quick, improved production efficiency.
8 contact pins and lead change mechanical connection into by welding, make the structure of lamp holder more firm, operate also convenient.
