The beneficial effects of the utility model: LED bulb lamp of the present utility model, by in its lampshade, establishing fin, the light of LED lamp is carried out multi-angle evenly to spread, improve the range of exposures of LED bulb lamp, simultaneously irradiation evenly, without multiple light source, direct projection can be avoided and dazzling problem obtains better illuminating effect.In addition, lampshade is threaded connection fixing, can be convenient to dismounting, maintains easily, and processes easy.

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, the utility model is limited.

Description of drawings

Below in conjunction with accompanying drawing, by the specific embodiment of the present utility model is described in detail, will make technical side grain of the present utility model and other beneficial effect apparent.

Fig. 1 is the decomposed structural representation of the utility model LED bulb lamp;

Fig. 2 is the combining structure schematic diagram of Fig. 1.

The specific embodiment

Technological means and the effect thereof taked for further setting forth the utility model are described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.

Shown in Fig. 1-2, LED bulb lamp of the present utility model, it comprises: lamp holder 1, the radiator 2 on lamp holder 1 of being connected, be located at several LED lamps 3 on the radiator 2 and be threaded connection lampshade 4 on radiator 2, lampshade 4 covers at LED lamp 3 tops, its inner surface is laid with fin 40, carry out the multi-angle diffusion with the light that LED lamp 3 is sent, enlarge range of exposures and the irradiation uniformity.

Described several LED lamps 3 are installed on the substrate 5, and LED lamp 3 is installed on the radiator 2 by this substrate 5, and are electrically connected with lamp holder 1.Substrate 5 adopts aluminium base, has good radiating effect, sheds thereby the heat that can in time LED lamp 3 be produced is passed to radiator 2.Described radiator 2 is the fin radiator, fin be evenly distributed on its circumference to around extend, be formed with cavity in it, these radiator 2 whole cup-shaped structures are adopted and are made of aluminum or copper, and have good heat dispersion.Substrate 5 places this radiator 2 upper end open ends, and 4 on lampshade is located at LED lamp 3 tops and is covered on this base pulls 5 peripheries.

Described lampshade 4 comprises cover body 41 and is embedded at the retainer plate 42 of cover body 41 openends, and cover body 41 is transparent hemispherical, and retainer plate 42 is the annular shape of corresponding cover body 41 openings.Described fin 40 is located at the inner surface of this

cover body

41,42 interior weeks of retainer plate are provided with screw thread 42l, correspondence position is provided with the screw thread 21 that matches on the radiator 2, and cooperatively interacting of screw thread 21 is connected on the radiator 2 on the screw thread 421 of lampshade 4 by retainer plate 42 and the radiator 2.In the present embodiment, the periphery of described radiator 2 upper end open ends is provided with external screw thread 21, and the 42 interior weeks of retainer plate of lampshade 4 are provided with the internal thread 421 that matches, by external screw thread 21 and cooperating of internal thread 421 lampshade 4 being screwed onto on the radiator 2.This kind mode that is spirally connected is convenient to the convenient dismounting of lampshade 4, when damaging appears in LED lamp 3 or its circuit, can be easily by keeping in repair behind the dismounting lampshade 4 etc., and can not cause the hard defects of lampshade 4 etc.Described cover body 41 also can be to be made into integration with retainer plate 42 and forms lampshade 4, simplified assembling process.Also can establish to inscribe the limiting section 22 of an annular on the Zhou Duan of the openend of described radiator 2, external screw thread 21 can be located on the madial wall of this limiting section 22, lampshade 4 can be fixed on by being spirally connected on the limiting section 22, thereby the periphery of lampshade 4 and radiator 2 peripheries keep globality, improve external aesthetic property.
