Description

The LED lighting bulb

The utility model relates to lighting engineering, specially refers to a kind of LED lighting bulb.

Background technology

The LED lighting engineering claims solid state lighting technology or led lighting technology again, is meant chip and each first device assembly are packaged together by certain technology, and making it becomes the luminescent device that can directly use, and is applied to the lighting engineering in each field; The LED lighting engineering be after incandescent lamp, gas-discharge lamp and electricity-saving lamp the 4th generation lighting engineering, good characteristic with low energy consumption, high light efficiency, long-life, no stroboscopic, oxious components such as its built-in material is not mercurous, tungsten are green illuminations truly.Such as: the solid light source of equal brightness, its power consumption has only 10% of incandescent lamp, and working life can reach 100,000 hours, can remedy the highly energy-consuming defective of incandescent lamp and gas-discharge lamp, can remedy the low light level illumination defective of electricity-saving lamp again, shown great attention to by all circles, the Ministry of Science and Technology is listed in " semiconductor lighting engineering " in the Eleventh Five-Year Plan science and technology development planning, to promote the development of related industry, the U.S. has formulated at " illumination plan of future generation " that consolidate illumination, and therefore states such as day Europe have also formulated the linked development outline;

The LED lighting engineering is progressively developed since the sixties in last century, recent decades, the LED device obtains paying attention in field of backlights always, such as being used as indicator lamp the earliest, use at aspects such as mobile phone, screen show again subsequently, progressively carry out the transition to the high-power LED illumination technology and use in special lighting field and general lighting field, just the reliability to the LED application product has proposed high requirement; The application form of product and traditional scheme also need be made adjustment;

Generally speaking, be subjected to the restriction of characteristic such as LED heat radiation, people's general passive heat radiation scheme that adopts in the high-power LED illumination application scheme solves problem, promptly adopt the heat dissipation metal area that strengthens lamp housing, utilize natural temperature differential to come radiating and cooling, such as: publication number C N1821651A, name is called; High-power LED street lamp is exactly that so this makes that the application cost of LED lighting engineering is too high, and promptly lamp body is huge;

Test shows: the LED of single 1W needs 12cm ²The aluminum heat sink can carry the required heat radiation requirement of its operating load, in actual applications, the LED illuminating street lamp of a 60W, need lamp housing (containing lamp body, the lampshade) heat radiation of the full aluminum material of long 80cm * wide 35cm could satisfy the requirement of putting in order the permanently effective work of lamp, this needs large-scale die casting equipment to produce, and mould and material cost be unusual height all;

In addition: the type of drive of LED illumination (string of light source, also, string and series-parallel connection) also is the factor of the whole lamp product quality of influence, particularly in the high-power illumination application scheme,, the cost of LED is even more important because of seeming, such as: in the LED of 50W illuminating lamp, the LED connected mode is 5W/ * 10 all parallel connections, single drives parameter is electric current 700MA, voltage is single magnitude of voltage, and constant current drives total electric current and needs 7000MA, and this makes that the power supply cost is too high; Simultaneously, damage (no matter be short circuit or open circuit) if any a LEDs, the electric current of 7000MA will branch to other light source, will cause circulation to damage other LED long-term work under, enlarge and damage the result, reduce the reliability of putting in order characteristic of a navigation light amount; Same in the LED of this 50W illuminating lamp, the LED connected mode is 5W/ * 10 all series connection, and single drives parameter is voltage 8V, and electric current is a single current value, constant current drives total voltage and needs 80V, open circuit if any a LEDs, whole lamp can't be worked, if any a LEDs short circuit, the tube voltage drop of other light source promotes, also will cause circulation to damage other LED under the long-term work, and enlarge and damage the result, reduce the reliability of whole characteristic of a navigation light amount; Comparatively speaking, the parallel way behind many strings (i.e. string and series-parallel connection) is preferred mode, and this just requires the inlet wire mode of lamp body power supply is made arrangements;

In a big LED illumination lamp body, its heat radiation, LED combination, the relatively easy realization of power supply combination, and the LED lighting engineering is reduced into the high-power LED illuminating lamp bubble that can replace existing common bulb, then need a comprehensive solution.
