Description

A kind of led support lamp
Technical field
The utility model relates to a kind of led support lamp, relates in particular to the led support lamp in a kind of photoelectric lighting field.
Background technology
Since 19th-century Edison invented incandescent lamp, brought in the dark bright and happy to the mankind.But because service life of incandescent lamp is short, electro-optical efficiency is low, and most of electric energy is used for generating heat, and small part is luminous, so energy consumption is large, will withdraw from gradually electric light source main flow illumination market at current Energy-saving Society.European Union progressively eliminates the application of incandescent lamp since on September 1st, 2009.
Second stage, the fluorescent lamp that common halogen-phosphate fluorescent material is made is after having experienced nearly 60 years course, although also exist many defectives, in constantly improvement, improve among the superiority of its quality, price make it in market always in occupation of suitable share.
Phase III, the 1970s and 1980s rare-earth trichromatic fluorescent powder is applied to energy-conservation fluorescent lamp at twentieth century.With respect to incandescent lamp, power saving fluorescent lamp is because its light efficiency is high, and the life-span is long, and obvious energy conservation becomes the major product of the global Green Lighting Project of twentieth century.But there is harmful mercury element in fluorescent lamp, not environmental protection by ultraviolet excited light-emitting; Stroboscopic; High pressure, there is potential danger in activated phosphor; Therefore the shortcomings such as ballast and starter power consumption are large still are not a kind of very good green illumination electric light sources.Along with the time is put off also and will be eliminated gradually.
Along with the electric light source scientific technological advance, semiconductor light-emitting-diode (LED) sixties appearred in twentieth century.Through decades development, LED has obtained the technical important breakthroughs such as extension, chip in the nineties, become the 4th generation electric light source, begin to enter the practical stage, and demonstrate the large advantage of its tool: optical efficiency is high; The light quality is good; Energy consumption is little; Life-span is long; Reliability and durability; Applying flexible; Safe and reliable; Environmental protection; Response time is short.Particularly through in recent years development, LED is just attracting global sight with its intrinsic superiority.For the application of LED, be that people expect the most extensively popularizing of general lighting field in the world.At present, the application of illumination LED is confined to the particular forms such as local lighting, decorative lighting, outline lighting, and people wish that urgently LED becomes general lighting light source of new generation, and each illumination company is all at the active development Related product.In addition, many buildings and Lighting designer are thought, use LED to can be them and increase many new designs, and they can utilize LED that the inspiration of oneself and design are specialized, so and the design sample that produces can be watched for people easily, this also is very beneficial for the universal of LED.With the perfect fusion of manufacturer, designer and user's imagination, the new application that developing traditional lighting light source can't be realized is most important.Along with the LED technology further develops, LED will become 21st century human revolutionary green illumination a new generation electric light source, will be global Lighting Industry prior development direction from now on.
Traditional LED encapsulating structure generally is with conduction or non-conductive adhesive is contained in chip in the undersized reflector or on the slide holder, forms with epoxy encapsulation finished the inside and outside connection of device by spun gold after, and its thermal resistance is up to 250~300 ℃/W.If adopt the LED packing forms of traditional type, will cause because heat radiation is bad junction temperature of chip to rise rapidly and epoxy carbonization flavescence, thereby cause the acceleration light decay of device until lost efficacy, even lose efficacy because the stress that rapidly thermal expansion produces causes open circuit.
The utility model content
In order to address the above problem, the utility model is intended to invent the LED-backlit source of a kind of good heat dissipation effect and long service life.
A kind of led support lamp comprises main body, guard shield, surface mount device, heat dissipating layer, lamp holder, driver and aluminum alloy casing, described main body top is provided with guard shield, the middle part of main body is provided with heat dissipating layer, the heat dissipating layer upside is provided with surface mount device, lower body part is provided with aluminum alloy casing, be fixed with driver between heat dissipating layer and the aluminum alloy casing, the lamp holder both sides are connected with aluminum alloy casing with heat dissipating layer respectively, described surface mount device inside is filled with silicon rubber, surface mount device comprises led chip, heat sink and aluminium oxide ceramics heat-radiating substrate, led chip is fixed in aluminium oxide ceramics heat-radiating substrate one side, be provided with heat sinkly between this led chip and the aluminium oxide ceramics heat-radiating substrate, and adopt half encapsulating structure.
Preferably, described heat dissipating layer is the heat conductive insulating plastic layer.
Preferably, be provided with some shallow slot shape aluminium alloy radiating pieces outside the described main body.
The beneficial effect of a kind of led support lamp of the utility model is:
1. surface mount device comprises led chip, heat sink and aluminium oxide ceramics heat-radiating substrate, be provided with heat sink between led chip and the aluminium oxide ceramics heat-radiating substrate, and adopt half encapsulating structure, accelerate heat radiation, inside at surface mount device, fill the high flexible silicone rubber of transparency, in the temperature range that silicon rubber bears, (be generally-40~200 ℃), colloid can the Yin Wendu abrupt change and cause the device open circuit, the flavescence phenomenon can not appear, part material takes into full account its heat conduction, heat dissipation characteristics to obtain good overall thermal characteristics, increases the physical life of surface mount device;
