Description

Strip source LED lamp

Technical field

The utility model relates to a kind of semiconductor light sources, further relates to a kind of strip source light emitting diode (LED) lamp.

Background technology

Light emitting diode (Light Emitting Diode, LED), basic structure is an electroluminescent semi-conducting material; be placed on a leaded shelf; then the surrounding epoxy sealing, play the effect of protection internal core, so the anti-seismic performance of LED is good.It is the device that utilizes the change on the electronics rank, energy band position when be combined in the hole in semi-conducting material to give off energy with luminous form, it has the advantages such as volume is little, the life-span is long, driving voltage is low, power consumption is low, reaction speed is fast, vibration strength is good, be element common in various application apparatus in daily life, and it has engendered the every nook and cranny in traditional lighting market.Strip source obtains the extensive use of every field more and more as a staple product classification of semiconductor illuminating light source.The LED lamp be a kind of can be the solid-state semiconductor devices of visible light with electric energy conversion, it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on a support, and an end is negative pole, and the other end connects the positive pole of power supply, makes whole wafer by epoxy encapsulation.Semiconductor wafer is comprised of two parts, and a part is P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is N-type semiconductor, is mainly electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer by wire, electronics will be pushed to the P district, and electronics with hole-recombination, then will send energy with the form of photon, the luminous principle of LED that Here it is in the P district.And the light wavelength color of light namely is to be determined by the material that forms the P-N knot.Initial LED is as the indication light source of instrument and meter, and various photochromic LED were widely applied in traffic lights and large-area displays screen afterwards, had produced good economic benefit and social benefit.

The crevice projection angle adjustable range is large as main feature take of fine quality, durable, energy-conservation for the LED lamp, and the brightness of 15W is equivalent to common 40W fluorescent lamp.High temperature resistance, moistureproof and waterproof, anticreep.Use voltage has: 110V, 220V are optional, the optional glass of outer cover or PC material.Lamp holder is the same with common fluorescent lamp.

The LED lamp adopts up-to-date LED light source technology, and digitisation appearance design, economize on electricity are up to more than 70%, and the LED light of 12W is equivalent to by force the fluorescent tube (be used for ballast and starter, the real power consumption of the fluorescent lamp of 36W is 42W to 44W) of 40W.The LED lamp life-span is more than 10 times of common fluorescent tube, and is almost non-maintaining, need not often change fluorescent tube, ballast, starter.The semi-conductor electricity light source of environmental protection, light is soft, and spectroscopic pure is conducive to user's sight protectio and healthy.The cold light source of 6000K is to visually refrigerant impression of people, and the differences of illumination intensities design of hommization more helps to concentrate on, and raises the efficiency.

At present, LED lamp and the contrast of common fluorescent lamp, advantage is as follows:

1, energy-conservation.2, the life-span is long.3, applicability is good, because the volume of single LEDs is little, can make any shape.4, the response time is short, be ns (nanosecond) other response time of level, and ordinary lamp and lantern is ms (millisecond) other response time of level.5, environmental protection, without poisonous metal, discarded object easily reclaims.6, lucuriant in design, luminous color is pure, and spectral region is narrow, and can become seven coloured silks or white light by the red-green-blue colour mixture.

Shortcoming: 1, price.2, also there is a big difference for the optical efficiency that can generally accomplish at present and theoretical light efficient.3, the life-span that can accomplish at present and theoretical life-span (10w hour), also there is a big difference.4, certain caloric value is still arranged.5, light decay can also significantly dwindle.

Existing LED strip source, that a metal edge frame (or frame of other materials) is installed on the metal circuit board that is used for the assembling chip, complete chip lay be connected connect after, directly adopt spot gluing equipment to cover the packing colloid that one deck contains fluorescent material in the formed cavity of frame.Yet in the overwrite procedure of packing colloid, because the air pressure of spot gluing equipment is unstable, difference between individuality and individuality can appear, thereby affect the uniformity of product, and the packaging technology that the packaged LED strip source is related and structure are comparatively complicated, utilize the cost of frame packing colloid relatively high.Existing LED lamp all has the problem of simplicity of design, moulding simplicity, function singleness simultaneously.
