In sum, for solving the deficiency on existing ball bulb lamp structure, need the convenient bulb lamp designing a kind of reasonable in design, good illumination effect.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of reasonable in design, convenient bulb lamp that good illumination effect, heat conductivility are good.
Object of the present invention realizes by following technical proposal: a kind of convenient bulb lamp, comprising:
Lamp socket;
Lamp holder, is arranged on below lamp socket, and the material of described lamp holder is aluminum alloy materials, this aluminum alloy materials is made up of following composition (with weight parts): Al:110-150 part, Si:0.1-0.45 part, Fe:0.46-0.65 part, Cu:4.5-8 part, Mn:0.45-0.8 part, Mg:15-25 part, Cr:1.8-4.5 part, Zn:1.5-2.3 part, Ti:0.8-1.3 part, Zr:2.5-3.8 part, PbS:1.5 ~ 3 part, rare earth element: 15-28 part;
Lampshade, setting spherical in shape and surround formation accommodating cavity with lamp socket;
Lighting means, is arranged in accommodating cavity, and described lighting means comprises multiple second illuminating sources of multiple first illuminating source that level puts and vertical display, and each illuminating source is connected successively and formed single loop;
Control panel, is detachably arranged on bottom lamp socket and is also electrically connected with lamp holder and loop, illuminating source place respectively.
For improving the characteristic such as intensity, corrosion resistance, heat conductivility of lamp holder, employing aluminum alloy materials prepares the lamp holder in the present invention.Aluminium alloy is a most widely used class non-ferrous metal structural material in industry, and its density is low, and strength ratio is higher, close to or exceed high-quality steel, and plasticity is good, can be processed into the section bar of various light fixture, has excellent electric conductivity, thermal conductivity and non-oxidizability.Wherein, Al-Mg-Si system alloy has good formability, weldability, machinable, there is moderate strength simultaneously, still can maintain good operability after annealing, but its intensity and thermal conductivity show slightly inadequate, affect the stability of the surface quality of finished product, heat conductivility and the work of finished product light fixture.
Therefore, the present invention preferably adopts the lamp holder of Al-Mg-Si system reasonable offer bulb lamp, but the present invention is on the basis of this aluminium alloy, first above-mentioned adjustment is carried out to the constituent of aluminium alloy and parts by weight thereof, to obtain thermal conductivity, the better aluminum alloy materials of combination property such as slight.
