Description

The New LED electricity-saving lamp

Technical field

The utility model relates to a kind of integrated heat spreader, power supply and the light source New LED electricity-saving lamp in one, and particularly a kind of built-in embedded power supply, use LED light emitting diode are as the electricity-saving lamp of light source.

Background technology

Light emitting diode (LED), especially white high-brightness LED is a kind of novel solid light source, is the inexorable trend of 21st century illumination application development, has remarkable advantages such as energy-conserving and environment-protective, life-span length.Compare with conventional fluorescent, its no mercury and fractional energy savings be greater than 50% excellent specific property, makes to use light fixture that the LED technology produces and have more and more widely market.

At first, in 60cm, the 120cm that is made up of low-power LED, the lighting source of 150cm, the electric current that needs is bigger, the heat that is produced is also bigger, especially with the rising of temperature, the light efficiency of LED luminous tube can present downward trend, and then influences the performance of whole light fixture.Therefore, suitable heat radiation is that this type of LED light fixture is kept one of key of normal operation.

Secondly, in the assembling process of light fixture, the tightness of structure also has to a certain degree influence to the normal operation of light fixture.Because each size of components has discreteness to a certain degree, lamp assembly is loosening can to cause parts loose contacts such as power supply, led circuit plate, and then has influence on the heat radiation of LED device; Each assembly of light fixture becomes flexible the orientation angle that may influence the LED luminous flat simultaneously, influences the illumination of whole light fixture.So the tightness of each assembly of light fixture need obtain to a certain degree raising by light.

The 3rd, in the heat dissipation of prior art, be comparatively common a kind of by miniature radiator fan, but in order to replace T8 type fluorescent tube and ballast thereof, the external diameter of LED light fixture must be consistent with the external diameter of fluorescent tube, i.e. 33mm.Because bigger volume, general radiator fan are difficult to arrange, realize auxiliary heat dissipation; Also be unsuitable for long-term running in addition the service life of general fan; And use special fan, and tend to increase considerably the cost of whole light fixture, be difficult to be accepted by market.

The utility model content

At above-mentioned defective, main purpose of the present utility model is to provide a kind of New LED electricity-saving lamp that utilizes the metallic support heat radiation.This lamp main body is made of cooling stand, can play heat radiation simultaneously and support all effects of other assemblies; Other parts of main body are plastics light-guiding shade and plastics firmware.Plastics firmware, plastics light-guiding shade and cooling stand constitute firm whole light fixture, power supply, led circuit plate are embedded in the cavity of whole light fixture, wherein heating part closely contacts with cooling stand, thereby the integral body that realizes LED device heat dispersion and whole light fixture assembling tightness improves, and then improves light fixture light efficiency and stability.

To achieve the above object; the utility model provides a kind of LED illumination cast light fixture product radiator structure; this structure comprises radiator bearer, plastics light-guiding shade and plastic fastener; radiator bearer is made by the good aluminium section bar of heat conduction; light-guiding shade and plastic fastener are closely pegged graft with radiator bearer axis groove and support two ends respectively; form cavity airtight and that have certain toughness, it has effect moistureproof and the inner LED device of protection.The LED device heating amount of cavity inside is disseminated in the air by radiator bearer.Certain dustproof and effect of increasing area of dissipation is arranged at the umbrella top of cooling fin in the middle of the radiator, and the umbrella top is fixed firmware simultaneously, can not rock along vertical and horizontal direction, and then strengthen and being connected of light-guiding shade.This structure good heat dissipation effect, be difficult for broken, have good assembling tightness, this light fixture can be replaced existing T8 type fluorescent tube and ballast.
