Abstract
The utility model relates to a cylindrical LED lamp based on a cylinder lamp holder with conductive radiating ribs, which at least comprises a lamp cap, an AC/DC circuit board, the cylindrical lamp holder, an LED array and the metal conductive radiating ribs; the LED array comprises a plurality of LEDs which are serially connected or serially and parallelly connected, and is arranged on the outer surface of the cylindrical lamp holder, and the serial connection of adjacent LEDs is realized through the metal conductive radiating ribs; and the cylindrical lamp holder comprises one or more circular lamp holders which are assembled together and can realize the high-power and miniaturization of the cylindrical LED lamp.
Description
Technical field
The utility model relates to and conduct electricity the LED illuminating lamp of fin a kind of having, belong to lighting based on the column lamp bracket.
Background technology
LED has luminous efficiency height, power saving and long characteristics of life-span, and the lighting of making light source with LED is at home, and illumination occasions such as office and traffic route are used widely.But single LEDs power is limited, so in lighting, often adopt many (tens of, hundreds of) LED series, parallel or connection in series-parallel to form led array.The LED columnar lamp generally adopts the high-brightness LED array, has been widely used in to substitute the ordinary incandescent lamp illumination.Because LED is very high to the temperature requirement of environment, the led array that high density is arranged can cause heat to accumulate in a large number in less the space in and can not distribute rapidly, thereby causes the decay of LED illumination and wear out rapidly, and shorten service life greatly.Therefore, the high-power miniaturized of LED columnar lamp is a great problem.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides conduct electricity the LED columnar lamp of fin having based on the column lamp bracket of a kind of led array configuration density height, good heat dissipation effect, thereby realizes the high-power miniaturized of LED columnar lamp.
The technical solution adopted in the utility model is: which comprises at least lamp holder, the AC/DC circuit board, the column lamp bracket, led array and metallic conduction fin, described led array is made up of plurality of LEDs series connection or connection in series-parallel, and being disposed at the outer surface of column lamp bracket, the series connection of adjacent LED connects by the metallic conduction fin.
Described column lamp bracket is assembled by one or several annular lamp brackets.
Described led array is by several, tens of or hundreds of LEDs is connected or connection in series-parallel is formed.
Column lamp bracket described in the utility model has improved the configuration density of led array greatly, and the metallic conduction fin had both played the effect of fin as being electrically connected between LED, thereby has realized the high-power miniaturized of LED columnar lamp.

Fig. 2 is the cross-sectional schematic of Fig. 1.
Fig. 3 is the structural representation of annular lamp bracket.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Fig. 1-2, the utility model comprises lamp holder 1, base 2, AC/DC circuit board 3, column lamp bracket 4, led array 5, metallic conduction fin 6, top cover 7, described led array 5 is made up of plurality of LEDs series connection or connection in series-parallel, and being disposed at the outer surface of column lamp bracket 4, the series connection of adjacent LED connects by metallic conduction fin 6.
Described led array 5 is by several, tens of or hundreds of LEDs is connected or connection in series-parallel is formed.AC/DC circuit board 3 makes alternating current be transformed into direct current, led array 5 is made up of plurality of LEDs series connection or connection in series-parallel, and be configured in column lamp bracket 4 and top cover 7 outer surfaces, the series connection of adjacent LED connects by metallic conduction fin 6, and metallic conduction fin 6 is not only as the effect that is electrically connected but also plays fin between LED.Described metallic conduction fin 6, its surface can be plane, corrugated or zigzag.
Described metallic conduction fin 6 can be configured in inside, the outside of column lamp bracket 4, or the inside and outside of column lamp bracket 4 disposes together.
Described column lamp bracket 4 is assembled by one or several annular lamp bracket 4a, 4b; Described annular lamp bracket 4a, 4b can be annular, oval ring, polygon annular or the special-shaped closed ring be made up of straight line and curve.
Described annular lamp bracket 4a, 4b can be the measure-alike cylindricality annulars in two ends up and down, also can be the different taper annulars of two end sizes up and down.
