Description
Technical field
The utility model relates to a kind of LED illuminating lamp, particularly a kind of U-shaped fluorescent tube LED electricity-saving lamp, can directly replace incandescent lamp and energy-saving fluorescent lamp, is used for illumination.
Background technology
The LED lamp kind that prior art can be used for replace incandescent and energy-saving fluorescent lamp is a lot.For example with the bulb lamp of metal, plastics or a ceramic heat sink, the one side of radiator is equipped with a metallic circuit (MPCB), and some LED are installed on MPCB, is mounted with the driver of LED in radiator, and half spherical cell-shell is arranged above LED; And for example be arranged on by some SMD or straw hat type LED the corn lamp that consists of on a plurality of PCB, a plurality of PCB that LED is installed consist of a cylindrical LED illuminator, add driver and electric connector; A kind of LED bulb of comprehensive bright dipping and for example, a LED illuminating source is arranged in a cell-shell, add driver and shell thereof and electric connector, the light source of described LED light source for being consisted of by several PCB that a plurality of LED elements are installed, or for the light-emitting section of a string at least LED chip or the light source of luminous tube are installed; Also have, profile is similar to A type incandescent lamp, the bubble lamp is divided into several lobes, every lobe has several LED, the A type LED lamp that the sky allowing air flow dispels the heat is hugged by bulb central authorities.In addition, also has various design.At present, the design of LED lamp is that a hundred flowers blossom, and is of a great variety.
The purpose of above-mentioned all kinds of LED lamps is all to substitute existing incandescent lamp and energy-saving fluorescent lamp, the volume of lamp, output light flux and photochromic close with incandescent lamp.But the energy efficiency of LED is high not enough at present, we know, wavelength is that the mechanical equivalent of light of the green glow of 555nm is 683lm/W, the mechanical equivalent of light of the warm white of 3500K is about 320lm/W, although the white-light emitting efficient of LED element has the report over 200lm/W at present, but common product, warm white, CRI(colour rendering index) luminous efficiency of LED element greater than 85 is about 130lm/W, if add the loss of light emission rate and the driver of light fixture, the luminous efficiency of the whole lamp of LED is generally in the 60-90lm/W left and right at present.It is energy efficiency about 30% left and right only of whole lamp; 70% the input energy of that is to say, have an appointment will become heat.So, make a volume and incandescent lamp is close, the also LED lamp close with incandescent lamp of output light flux, one of its key is exactly how to dispel the heat.
With a whole lamp of LED, no matter the how heat conduction of its lamp inside, its final heat radiation be the heat radiation of whole lamp outer surface and itself and surrounding air heat exchange, comprise that hot conduction and convection dispels the heat.Generally all lower than 100 ℃, its heat-radiation heat-dissipating is limited due to the temperature of the whole lamp outer surface of LED, but the radiation coefficient that improves the lamp surface to be improving heat loss through radiation, and this is also one of the factor that should consider of lamp design.Simultaneously, we know, any static gas is all good heat guard, the thermal conductivity of air is only 0.024W/mK, improve the heat exchange heat radiation of LED lamp and surrounding air, will increase on the one hand the contact area of lamp and air, on the other hand, the most important thing is to improve flowing of air, mobile air can effectively take away the heat of lamp, allow LED lamp efficiently radiates heat.For example someone studies in radiator a small power electric fan is installed, can very effectively accelerate circulation of air, efficiently radiates heat, thereby can be made into the large LED lamp of volume small-power, but in the general lighting lamp provided with fan, be not easy to be accepted by market.
At present, how to make long-pending, the output light flux close with incandescent lamp of lamp body enough height, cost is low, efficient is high LED electricity-saving lamp, be still a problem anxious to be resolved.
