Abstract
The utility model relates to a novel LED (light-emitting diode) lamp which comprises a radiating stem, a lampshade, a LED light source and a driving device, wherein the lampshade is fixed on the radiating stem, the LED light source is arranged in the lampshade, the driving device is connected with the LED light source, the lower end of the radiating stem is provided with a radiator, the radiator is composed of a middle radiating body and a lower radiating body, the upper end of the radiating stem is provided with at least two radiating bodies arranged at a certain interval, the outer side of each radiating body is provided with a substrate, the LED light source is fixed on the separate, and the LED light source and the driving device are separated through the middle radiating body. According to the utility model, the radiating area of a common LED lamp bulb is expanded by multiple times, when the radiating capacity of the upper radiating stem is insufficient, the length of the lower radiator can be flexibly adjusted, so that the LED lamp bulb meets the requirements of different powers; and the novel LED lamp has the advantages of simple structure, good heat dissipation, low temperature of a drive space, and the like.
Description
Technical field
The utility model belongs to the LED technical field of semiconductor illumination, particularly be a kind of Novel LED lamp.
Background technology
Pendent lamp be in the hotel, decorative lighting places such as dining room, household, meeting room use lighting very widely.The lighting source that is adopted in the pendent lamp is an incandescent lamp bulb, and the outward appearance of incandescent lamp bulb is candle or spheroidal.In the pendent lamp a plurality of incandescent lamp bulbs are installed, for bigger pendent lamp, the quantity of incandescent lamp bulb can reach 20 or more.In the pendent lamp power of incandescent lamp bulb one be 40W, 60W, 100W, under the corresponding same light flux, adopt the power of the LED bulb of LED technology to have only 5W, 9W, 15W.By the incandescent lamp calculating that replaces 40W in the pendent lamp of one 20 stature with the LED bulb of 5W, the power of 20 incandescent lamps will reach 800W, and the power of 20 LED bulbs then has only 100W.It is thus clear that, adopt more energy-conservation LED bulb to replace incandescent light bulb, for the energy consumption that reduces pendent lamp crucial effect is arranged.
At present, the LED bulb that has had some to be used for replace incandescent bubble on the market since existing LED bulb be based on more the outward appearance of the incandescent lamp bulb that will substitute design; Radiating piece be positioned at the bulb bottom and size less; Aspect heat radiation, do not break through, cause the area of dissipation of LED bulb little, power can't be done greatly; Luminous flux can't reach the requirement of the above incandescent lamp bulb of 40w, thus can not replace comprehensively in pendent lamp, use from vehement bulb.
Summary of the invention
The purpose of the utility model is to provide a kind of have better heat dispersion and the lower Novel LED lamp that drives space temperature.
The utility model solves the technical scheme that its technical problem adopted: a kind of Novel LED lamp; Comprise the heat radiation stem stem, be fixed on the lampshade of heat radiation on the stem stem, place the led light source in the lampshade, the drive unit that is connected with led light source; Said heat radiation stem stem lower end is provided with radiator; Radiator is made up of middle radiator and following radiator, and heat radiation stem stem upper end is provided with at least two radiators with certain intervals, and the radiator outside is provided with substrate; Led light source is fixed on the substrate, and said led light source and drive unit are through middle radiator separately.
Said radiator and lampshade fasten.
Said drive unit places down in the radiator.
Said drive unit constitutes by driving shell and driving power.
Said radiator is that cross section is the radiator of V-shape.
Said heat radiation stem stem and radiator are a global facility.
The outer surface or the inner surface of radiator and following radiator are provided with striped or fin in said.
Through adopting above-mentioned technical scheme; The beneficial effect of the utility model is: the utility model is an area of dissipation of having expanded common LED bulb several times; When the heat-sinking capability of the heat radiation stem stem on top is not enough; Can adjust the radiator length of bottom flexibly, make the LED bulb satisfy the requirement of different capacity, it has advantages such as simple in structure, that thermal diffusivity good, the driving space temperature is low.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional view of the utility model heat radiation stem stem.
The specific embodiment
Like Fig. 1, shown in Figure 2, a kind of Novel LED lamp of the utility model comprises heat radiation stem stem 1, is fixed on the lampshade 3 of heat radiation on the stem stem 1, places the led light source 2 in the lampshade, the drive unit 4 that is connected with led light source 2; Said heat radiation stem stem 1 lower end is provided with radiator 5; Radiator 5 is made up of with following radiator 7 middle radiator 6, and heat radiation stem stem 1 upper end is provided with at least two radiators 11 with certain intervals, and radiator 11 outsides are provided with substrate 10; Led light source 2 is fixed on the substrate 10; Said led light source 2 was opened through middle radiator with drive unit 4 in 6 minutes, and said radiator 11 fastens with lampshade 3, and said drive unit 4 places down in the radiator 7; Drive unit 4 constitutes with driving power 9 by driving shell 8; Radiator 11 is the radiator of V-shape for cross section, and heat radiation stem stem 1 is a global facility with radiator 5, and the heat that led light source 2 sends conducts to radiator 5 through heat radiation stem stem 1; The outer surface or the inner surface of radiator 6 and following radiator 7 are provided with striped or fin in said, increase the heat-sinking capability of radiator 11.
An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
