Description

The LED globe lamp that a kind of primary colours are adjustable

Technical field

The present invention relates to the LED field of illumination lamp technology.

Background technology

It is from flame that people utilize light source, incandescent lamp, the fluorescent lamp of gas luminescence, present electricity-saving lamp also is to lean on gas luminescence, it is that the form of the high electric current of AC rectification direct current voltage rise is given me a little the interior inert gas of pipe of lighting a lamp nothing more than, the conversion of its luminous primary colours is to change luminous primary colours by the gas of adding heterogeneity, though it is than fluorescent lamp and incandescent lamp economize on electricity, but also not possessing from vehement lamp, it can not adapt to energy-conservation requirement under outstanding occasion (because switch also can make electricity-saving lamp lose purpose of energy saving frequently, switch also very easily causes the damage of electricity-saving lamp frequently).At present people have begun to utilize LED as our energy-conservation light source, the structure of LED and principle of luminosity before 50 years people understood the ABC that semi-conducting material can produce light, 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.Led light source is very energy-conservation as everyone knows, it can 80% than from vehement Lantern Festival, than daylight lamp energy-saving 50%, led really is applied to the central illumination of our daily life seldom at present, most of led is applied to exterior decoration illumination, for example wall body decoration illumination and Landscape Lighting such as rainbow tube etc. of the outer facade of the flash illumination of acrylic word and high building.Mention the urban decoration and throw light on that we just associate neon light very naturally, the light that traditional neon light sends very bright soft (light of different colours is that inert gases different in the fluorescent tube determines) is given people one and is felt more really, though but the light that present led rosehead sends is colourful, but give the sensation of a kind of illusion of people, with regard to by the outer facade ted ornament lamp of high building, the only dazzle that sends that night, we saw, though rainbow tube is that we see a light that sends is that several the light that send are arranged, give the sensation of people's dim eyesight, reason is that led is luminous even unlike traditional neon light, the generation of dazzle is that led shines face shield with spot light and the light that reflects, because the spot light of being formed by numerous different colours in the led rainbow tube, the illumination that they send is mapped on the face shield because face shield adopts circular shape mostly, though face shield has adopted semi-transparent material, because luminous point does not have the cambered surface that the uniform effect of diffused light is added face shield formation close to the face shield distance, so reflect only towards different directions, the someone has designed anti-glare LED light fixture for this reason, can be with reference to Chinese patent literature CN102330898A.

We mention the led street lamp again, the high-power LED of the most of employing of led street lamp at present luminous tube, and a maximum at present difficult problem is to solve the led heat radiation, and temperature control electric current of advanced person etc. is arranged.Mention street lamp we to know that traditional street lamp sends only amber, we know that the primary colours (color) of not sharing the same light are for penetrating for example mist, rain, snow is different, feel very bright from light (ted sends cold light source) though shine the road surface fine night, but the ability of the primary colours penetrating fog of the light that it sends but is very poor, so the street lighting in city is still adopted to come to the city night lighting just as amber high-pressure mercury lamp mostly now, because the illumination of the most suitable avenue of primary colours under season and various weather of the light that high-pressure mercury lamp sends, thus people just always so far with high-pressure mercury lamp as city street lighting at night.Because the chip of different led has determined the primary colours of the light that sends, has developed redness, blueness, green, white etc. at present.We know that colour television set is with red, blue, green, three kinds of motley colors that color is adjusted out, if but directly the LED luminous tube of these three kinds of primary colours is lined up, directly adjust the illumination as the city, like that to we talk about previously such, so just probably make the driver, the pedestrian is dazzled, and traffic accident so very easily takes place, and is difficult to solve the needed illumination primary colours in city at present.
