Description
Technical field
The utility model relates to the illuminator of a kind of LED of use as light source, particularly possesses the LED intelligent lighting device of intelligent temperature control and automatic early-warning function.
Background technology
LED is Light Emitting Diode, and Chinese is light-emitting diode.The basic structure of LED bulb is an electroluminescent semi-conducting material, with epoxy sealing by and connect with lead-in wire.Great power LED is exactly wherein a kind of high brightness LED, with respect to low-power LED, single power of great power LED is higher, and brightness is brighter, it is to allow semiconductor lighting move towards a most important ring in the general lighting field, has gone on the road of application now gradually.The advantage of great power LED is quite unique: great power LED uses supply voltage lower, and high voltage source is safer than using, and is specially adapted to the public place; The great power LED consumed energy reduces 80% with the incandescent lamp of light efficiency, and energy-conserving and environment-protective more quite meet the theme of current green energy resource, energy-conserving and environment-protective; The various relatively lamp holders of each unit LEDs sheet, build is all quite little, if do not turn on light, almost discovers the existence less than them; Under light decay was initial 50% situation, the stability of great power LED was very high, and long service life reached more than 100,000 hours, after the installation hardly with changing; Because semi-conductive peculiar property, the response time of LED lamp is a nanosecond, and the response time of incandescent lamp is a Millisecond, and the response time of LED is faster; The LED lamp is according to the change of Current Control or structure, can realize redness, orange, yellow, green even white photochromic; LED is a kind of environment friendly and pollution-free new type light source, and not only the course of work does not have poisonous metal mercury, and the also safer environmental protection of production process.Generally speaking, the conventional relatively light source of LED itself has the brightness height, operating voltage is low, power consumption is little, miniaturization, the life-span is long, shock-resistant and stable performance etc. is quite outstanding advantage, and development prospect is very wide.
The LED light fixture generally is made up of LED light-emittingdiode, PCB circuit board and shell three parts.The brightness of light-emittingdiode is by brightness of led chip naked core and the decision of lamp body packaging appearance, and its life-span is determined by led chip operational environment and quality; As the carrier of light source, all electronic circuits of LED light fixture all on the PCB circuit board, the life-span of the light fixture that its material and processing technology directly influence and failure rate; Shell is as the light-mixed layer and the protective layer of light fixture product, and is also very important, requires performances such as excellent waterproof, heat radiation and protecting against shock.
But, utilize the LED illumination also to have many problems, particularly for great power LED.At first; LED costs an arm and a leg, and the price of several LED just can be suitable with the price of an incandescent lamp, and common every group of lamp holder needs many LED that do not waited by quantity to constitute; particularly the price of great power LED is higher, therefore protects the LED prolongation just quite important its useful life.Secondly, LED is a kind of semiconductor components and devices, and also there are problems such as the intrinsic heat radiation of semiconductor components and devices, light decay, light efficiency in it, and for example: the temperature back LED brightness that raises reduces, and too highly then may cause permanent light efficient to reduce even damages.Because it is very big that great power LED is influenced by heat, at high temperature its life-span reduces significantly, causes present LED lamp based on small-power.For the further marketization, improve the scope of application of high-power LED lamp, need badly and overcome the problems referred to above.The particularly requirement of the heat radiation in the course of work should improve the heat dispersion of light fixture on the whole through all links of LED epitaxial wafer, chip, encapsulation and even application.At present, also there is not a product to address the above problem on the market comprehensively.
