Description

A kind of LED module

Technical field

The utility model relates to a kind of lighting device, be meant especially and comprise a radiating shell, an arrangements of electric connection and a led light source, and wherein, this radiating shell is to be made by the good material of heat-conductive characteristic, especially make by metallic aluminium, again, this led light source is arranged in this arrangements of electric connection, it comprises that an anodal tie point, a negative pole connect point, a series connection resistance unit and a LED luminescence unit, wherein, this LED luminescence unit has some LED luminous tubes, and the LED illuminating module for being connected in series and concerning between some this LED luminous tubes.

Background technology

As everyone knows, progress along with society, people improve constantly the requirement of daily life quality, the various apparatus that can promote people's quality of the life occur in a large number, and lighting device is because the original characteristics of himself, from inventing, it just must be subjected to people's common concern, and traditional lighting device, such as bulb, its operation principle mainly is to utilize an one metal wire line that electric energy is converted into luminous energy, and this traditional bulb must be extra in concrete luminous process give out a large amount of heat energy, and then cause and the part electric energy is converted into heat-energy losses falls, situation about wasting energy for no reason appears.Simultaneously, traditional lighting device is often because the restriction of its principle of luminosity, and greatly reduces himself service life and luminous efficiency.

And along with a kind of LED photophore has appearred in the progress of society, people just understand the ABC that semi-conducting material can produce light before 50 years, and first commercial diode results from nineteen sixty.LED is the abbreviation of English light emitting diode (light emitting diode); its basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, uses epoxy sealing then all around; play the effect of protection internal core, so the anti-seismic performance of LED is good.

And the groundwork principle of LED is, the wafer that the core of light emitting diode is made up of p type semiconductor and n type semiconductor has a transition zone between p type semiconductor and n type semiconductor, be called p-n junction.In the PN junction of some semi-conducting material, the minority carrier of injection and majority carrier compound tense can discharge the form of unnecessary energy with light, thereby electric energy directly is converted to luminous energy.PN junction adds backward voltage, and minority carrier is difficult to inject, so not luminous.This diode that utilizes the making of injection electroluminescence principle is generally called LED light emitting diode.When it is in the forward duty (two ends add forward voltage), when electric current flowed to negative electrode from the LED anode, semiconductor crystal just sent the light from ultraviolet to infrared different colours, the power of light and current related.

Again, exactly because the aforesaid textural association mode of LED, so LED exists the good operation characteristic in concrete the use, at first, aspect voltage, LED uses low-tension supply, supply voltage is between 6-24V, different and different according to product, so it is a safer power supply of ratio use high voltage source, be specially adapted to the public place; Secondly, aspect usefulness, its consumed energy reduces 80% with the incandescent lamp of light efficiency; Once more, aspect applicability, its volume is very little, and each unit LEDs small pieces is squares of 3-5mm, thus can be prepared into the device of different shape, and be suitable for variable environment; And then, aspect job stability, its work 100,000 hours, light decay only is initial 50%; Further, aspect its response time, the response time of conventional incandescent is a Millisecond, and the response time of LED lamp is a nanosecond; For the glow color aspect, it changes electric current can variable color, and light emitting diode is adjusted the band structure and the band gap of material easily by chemical modification method, realizes that the green blue orange of reddish yellow is multicolor luminous.Be red LED during as little electric current,, can become orangely successively that yellow be green at last along with the increase of electric current; But last, in price, the price comparison costliness of LED compares to incandescent lamp, and the price of several LED just can be suitable with the price of an incandescent lamp.

Comprehensively above-mentioned, the LED semiconductor lighting is compared with the traditional lighting technology, has long clear superiority of economize on electricity and life-span.But brightness also has a certain distance.For brightness is provided, it is common that people constantly research and develop great power LED, and the LED of power more than 0.5w is called high-power LED.Common LED operating current is about 20ma, and power is about 0.06w.And restrict the universal principal element of high-power LED at present is price.The price of common led is at several maos, and the price of high-power LED is at several yuans, and the great power LED of application layer is more than tens yuan.

So LED is as a kind of lighting device, its characteristics of luminescence and other kinds specific character obviously are better than traditional lighting device, but the major defect that limits its development is it is applied to the general lighting field, production cost higher.
