By adopting the design, the heat radiating area of the LED bulb is greatly increased; the increase of radiation of the LED bulb is facilitated. Thus, the service life of the LED bulb is prolonged; the practicability of the LED bulb is further improved.

Description

High-efficiency heat radiating LED bubble lamp

Technical field

The utility model relates to a kind of lighting apparatus, especially a kind of LED bubble lamp of high efficiency and heat radiation.

Background technology

Traditional lighting device is mainly incandescent lamp and fluorescent lamp, and wherein incandescent lamp is because the features such as cheap and application is convenient are used widely, but because its luminous efficiency is low, and use cost is high the later stage, has brought puzzlement to the use of incandescent lamp; And fluorescent lamp luminous efficiency has increased significantly compared with incandescent light fitting, but due to short and being eliminated by market gradually in its service life.

LED, as rising industry, has been widely applied in the luminous scene of various needs, and the development of the LED technology of particularly coming in is beaten as improving LED luminance, and the parent who is therefore also subject to illumination market looks at.

LED illumination is the third generation light source continue incandescent lamp and fluorescent lamp after, have efficiently, environmental protection, the life-span is long, colour rendering index is high, as incandescent lamp can instantaneous starting etc. feature, be one of Present Global high salary technical field most with prospects.But the radiating effect of LED lamp is poor, shortened the service life of LED lamp,, had a strong impact on the long term growth of LED lamp.

Utility model content

The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, and provides a kind of simple in structure, the high-efficiency heat radiating LED bubble lamp of good heat dissipation effect.

In order to achieve the above object, a kind of high-efficiency heat radiating LED bubble lamp that the utility model is designed, it comprises lamp holder, Lamp cup and lampshade, at the top of Lamp cup, is fixed with wiring board, and wiring board is provided with LED chip, and wiring board is connected by wire with LED chip; Described lampshade is billiard table shape, described Lamp cup comprises lamppost and fin, lamppost and fin are structure as a whole, the lateral wall of described lamppost be provided with a plurality of fin and between two adjacent fin by arc-like sheet, connect into the integrative-structure of " loudspeaker " shape, a plurality of fin stretch out from the bottom to top along lamppost, it is lower narrow wide that fin is, fin longitudinally cross section is trapezoidal, and fin tip position, higher than the tip position of arc-like sheet, is longitudinally provided with a plurality of arc grooves on described fin.

In such scheme, the gap between described fin bottom is 3-5mm, and the gap between top is 5-8mm.

In such scheme, the gap between the Wei4mm， top, gap between described fin bottom is 5.5mm.

As preferably, described lamppost is provided with 4 fin, and each fin is provided with 2 arc grooves.

As preferably, described Lamp cup adopts aluminium section bar to form, and outside is provided with antirust coat.

The resulting LED bubble of the utility model lamp, Lamp cup comprises lamppost and fin, the two forms by aluminium section bar, lamppost stretches out from the bottom to top and is " loudspeaker " shape along lamppost, and each fin is provided with 2 arc grooves, this design has strengthened the area of dissipation of LED bubble lamp greatly, contributes to increase the heat radiation of LED bubble lamp, thereby extended the service life of LED bubble lamp, more increased the practicality of LED bubble lamp.
