Abstract

The invention discloses an LED (light-emitting diode) lamp, particularly a split-type LED lamp which comprises a shell, a bulb, an aluminum substrate, a heat dissipater and a transformer. The shell consists of a lamp cover and a base; the bulb and the aluminum substrate are fixedly arranged on the lamp cover; the heat dissipater and the transformer are fixedly arranged on the base; the lamp cover is connected with the base by a thread; and after being folded, the aluminum substrate is in close contact with the heat dissipater. The split-type LED lamp comprises a lamp cover and a base, and the internal components of the split-type LED lamp comprise two parts. When the components of the split-type LED lamp need to be detached for maintenance and change, the lamp cover and the base can be screwed off to check rapidly and very conveniently.

Description

A kind of separated LED lamp

Technical field

[0001] the present invention relates to a kind of LED lamp, relate in particular to a kind of separated LED lamp.

Background technology

[0002] LED, because its long service life, it is low to consume energy; Volume is little, and stability is high, and environmentally safe; And it is more and more welcome; Initial LED is as the indication light source of instrument and meter, and various afterwards photochromic LED have obtained extensive use in traffic lights and large tracts of land display screen, produced good economic benefits and social benefit.With 12 inches red traffic lights is example, is to adopt the long-life originally in the U.S., and 140 watts of incandescent lamps of low light efficiency are as light source, and it produces the white light of 2000 lumens.Behind Red lightscreening plate, light loss 90%, the ruddiness of only remaining 200 lumens.And in newly-designed lamp, Lumileds company has adopted 18 red LED light sources, comprises circuit loss, and power consumption is 14 watts altogether, can produce same light efficiency.Now, the LED lamp is not widely used in every field especially.

In the prior art, the structure of common illumination LED lamp is that lamp pearl, aluminium base, radiator and transformer tighten together basically; Lamp housing divides base and lampshade, and after on the base, lampshade closed to get final product with lamp pearl, aluminium base, radiator and transformer overall fixed; Though simple in structure, it is interfixed basically and can't dismantle separately, wherein a certain parts damages by parts not; Need integral demountings such as LED be opened; The transformer that particularly damages easily needs top lamp pearl, aluminium base and radiator are all taken out just and can repair or replace, very trouble.

Summary of the invention

The object of the present invention is to provide a kind of separated LED lamp, solved maintenance of LED lamp and the inconvenient problem of replacing parts in the technology.

For addressing the above problem, the technical scheme that the present invention taked is:

A kind of separated LED lamp; Comprise lamp housing, lamp pearl, aluminium base, radiator and the transformer formed by lampshade and base; Described lamp pearl and aluminium base are fixedly mounted on the lampshade; On described radiator and transformer were fixedly mounted on the base, described lampshade and base be for being threaded, and close up the back aluminium base and closely contact with radiator.

For making the present invention play better technique effect:

Technical scheme further is that above-mentioned lamp pearl and power line interconnects through contact chip.

Technical scheme further is that above-mentioned lampshade and base junction also is provided with sealing ring.

Adopt the beneficial effect that technique scheme produced to be: integral body of the present invention is divided into lampshade and base two parts, and its internal part also is divided into two parts, when the dismounting maintain and replace, can directly turn on lampshade and base, can be checked through problem fast, and is very convenient.
