Description

A kind of outdoor low voltage LED illuminating lamp

Technical field

The utility model relates to lighting technical field, particularly relates to a kind of outdoor low voltage LED illuminating lamp.

Background technology

Illumination during for open air (lacking civil power) operation, conventional method is to use incandescent lamp and fluorescent lamp.Not enough below but the two exists: (1), lamp body adopt glassware, and be frangible, inapplicable field work; (2), energy consumption is high, luminous efficiency is low, the incandescent lamp luminous efficiency generally has only 12LM/W, fluorescent lamp has had improvement on the basis of incandescent lamp, but its luminous efficiency also has only 25LM/W; (3), the lamp body discarded object has harm to environment, incandescent lamp is very serious to the pollution of environment with the discarded object of fluorescent lamp, particularly the mercury pollution in the fluorescent lamp; (4), the life-span is short, the life-span of incandescent lamp, generally about 1000H, the life-span of fluorescent lamp approximately was 3000H.

Along with the development of solid state lighting, LED (Light Emitting Diode, the light emitting diode) illumination that integrates multiple advantage just progressively strides forward to third generation new type light source at present.LED changed the incandescent lamp tungsten filament luminous with the luminous principle of fluorescent lamp tricolor powder, utilize electroluminescence, have that light efficiency height, radiationless, life-span are long, an advantage of low-power consumption and environmental protection.

But at present all on the market LED lamps yet come with some shortcomings, existing LED lamp otherwise because the voltage problem scope of application is limited to, or be because lamp holder is a plug-in, use inconvenient.At present mostly the LED lamp relates generally to that (civil power is our said alternating current (AC) in order to use civil power; The composition of alternating current comprises: three kinds of voltages, electric current, frequency; Its frequency can be divided into 50HZ (hertz) and two kinds of 60HZ (hertz), and voltage distributes by 100V to 240V.Machine room is generally introduced 380V, and the civil power of 50HZ is gone into machine room, but the voltage of the single-phase 220V that the power rectifier module of equipment is used).At present mostly the LED lamp scope of application all is use under stable high pressure conditions, perhaps only is under the indoor situation that burning voltage arranged, to use; And when not having sufficient stable field work civil power, particular surroundings, just seem not enough; Because outdoor requirement to the LED lamp is just higher, not only require its good heat dissipation, low-power consumption, high-luminous-efficiency low, and require that it is non-friable, long-life, the convenient use.

The technical scheme of the utility model is:

A kind of outdoor low voltage LED illuminating lamp comprises transparent lamp shade, lamp body and lamp holder, and said lampshade covers in the top of said lamp body, and the bottom of said lamp body is connected with said lamp holder; Said lamp body comprises that input voltage is the constant-current control circuit plate of AC/DC12V and the Lamp cup that is welded with the heat-conducting substrate of LED and is hollow structure; The sealing of one baffle plate is positioned at the opening on the top of said Lamp cup; Be electrically connected with LED on the top end face of said heat-conducting substrate; The bottom face of said heat-conducting substrate is carried on the said baffle plate; Dismountable top and the said LED that covers in said lamp body of said lampshade stretches in the said lampshade, and the bottom of said Lamp cup is connected with lamp holder, and said constant current control chip is contained in the said lamp holder; Said lamp holder electrically connects with said heat-conducting substrate and the said constant current control chip that is welded with LED respectively, and said lamp holder and extraneous AC/DC12V power supply electrically connect.

Preferably, said Lamp cup is that plastic material and lateral surface protrude out a plurality of radiating fins.

Preferably, said Lamp cup is circular cone shape, and said radiating fin is radial to convexedly stretch on the lateral surface of said Lamp cup.

Preferably, said lamp holder comprises metal shell and is the insulator of hollow structure that said metal shell is coated on outside the said insulator.

Preferably, said metal shell is E27, E26 or E14 structure.

Preferably, said outdoor low voltage LED illuminating lamp also comprises the metal bound edge, and said metal bound edge is coated on outside the junction of said surely lampshade and Lamp cup.

Preferably, an end of said metal bound edge is sheathed on outside the said lampshade, and another of said metal bound edge and said Lamp cup are threaded.

Metal material described in the utility model mainly is meant aluminium.

The utility model comprises that transparent lamp shade, lamp body, lamp holder, the input voltage of engineering plastics material are the constant-current control circuit plate of AC/DC12V and the Lamp cup that is welded with the heat-conducting substrate of LED and is hollow structure; The utility model adopts engineering plastics+aluminum component manufacturing, its height from 90cm is fallen all can not cause cracked, effectively preventing because Personal Risk and the environmental pollution that the glass fragmentation causes; And common E27, E26, the E14 lamp holder of the utility model employing, make it easy to use extensively; Especially LED is luminous is one--the process of light conversion, because the utility model adopts the Lamp cup of round table-like structure and constant-current control circuit plate that input voltage is AC/DC12V and the heat-conducting substrate that is welded with LED, the lateral surface of Lamp cup forms a plurality of radiating fins; The radiation shape that a plurality of radiating fins are rounded, the radiating fin of circle out shape increases the area of dissipation of radiating seat, when the led light source operating illumination; The heat that led light source produced is through heat-conducting substrate, and metal baffle reaches Lamp cup; In time promptly distribute by radiating fin again; Thereby improve the radiating effect of LED electricity-saving lamp, avoid shorten the light decay of the led light source that slows down the service life of led light source; Heating is few, and loss is little; Adopt the present invention more energy-conservation 80% than incandescent lamp as light source, more energy-conservation 40% than fluorescent lamp, the life-span on average can reach 30000-40000H, and incandescent lamp is with the life-span of fluorescent lamp head and shoulders above; Luminous efficiency can reach 75-80LM/W, promptly identical luminosity, and the used wattage of LED is minimum.
