Description

A kind of LED lamp

Technical field

The utility model relates to a kind of LED lamp.

Background technology

Along with the development of technology, the LED solid light source is used increasingly extensive, and it is also more and more as lighting source.Because the big characteristic of the volume small-power of illuminating LED own, it must possess heat abstractor, generally adopts through the metal shell heat radiation at present.Existing radiating shell generally comprise be used for to the heat dissipation lateral wall of external world heat radiation and with the integrated base plate that is used for fixing light source board of heat dissipation lateral wall; This radiating shell generally perhaps carries out the last moulding of machining through adding after the extrusion modling through the pressure casting method manufacturing; These processes have determined that its wall thickness of the radiating shell after the moulding is bigger; Therefore more with material, weight is bigger, and material cost is higher.

The utility model content

The utility model technical problem to be solved is the deficiency that overcomes prior art, provides a kind of cost low, in light weight, easily manufactured LED lamp.

The technical scheme that the utility model adopted is: the utility model comprise lamp holder, radiating shell, the said lamp holder of connection and said radiating shell insulated connecting piece, drive circuit, with said drive circuit be surrounded and with the insulating element of said radiating shell insulation, have the light source board assembly of LED; Said LED lamp also comprises the heat radiation chassis; Said radiating shell is the heat-dissipating casing that adopts spinning or punching press or drawing process to process; Said light source board assembly and said heat radiation chassis fix and transmit heat, and said heat radiation chassis and said radiating shell are fixedly connected and heat loss through conduction.

Be fixedly connected through compression fit between said heat radiation chassis and the said radiating shell.

Said LED lamp also comprises lampshade, and said lampshade is tightly connected with said radiating shell mutually, in said light source board assembly is surrounded on.

Fix sealing through fluid sealant between said lampshade and the said radiating shell.

Said LED lamp also comprises reflector, and said reflector is corresponding with the LED position of said light source board assembly.

Said insulating element comprises insulation bucket and insulating lid.

Perhaps, said insulating element is a highland barley paper.

The aluminium manufacturing is adopted on said radiating shell, said heat radiation chassis.

The model of said lamp holder is E27 or E26 or E14 or E12 or GU5.3 or GU10 or GX5.3 or GX53 or GZ5.3 or G53 or G4.

The beneficial effect of the utility model is: because the utility model comprises the heat radiation chassis; Said radiating shell is the heat-dissipating casing that adopts spinning or punching press or drawing process to process, and said light source board assembly and said heat radiation chassis fix and transmit heat, and said heat radiation chassis and said radiating shell are fixedly connected and heat loss through conduction; Through being separated with said heat radiation chassis, said radiating shell makes ways of connecting again; Its wall thickness of heat-dissipating casing that adopts spinning or punching press or drawing process to process can reduce than existing radiating shell, and method is easy, and the later stage assembling is easy; If employing spin-on process; More can save the expense of mould, cost is lower, so the utility model cost is low, in light weight, easily manufactured.

The specific embodiment

Embodiment one:

Like Fig. 1, shown in Figure 2, the LED lamp of present embodiment comprises lamp holder 1, radiating shell 2, connect said lamp holder 1 and said radiating shell 2 insulated connecting piece 12, drive circuit 3, with said drive circuit 3 be surrounded and with the insulating element of said radiating shell 2 insulation, the light source board assembly 4 that has LED, heat radiation chassis 21, lampshade 5, said radiating shell 2 is the heat-dissipating casings that adopt spin-on process to process; Can save the expense of mould; Cost is lower, can certainly adopt punching press or drawing process to process, and said light source board assembly 4 fixes and transmit heat with said heat radiation chassis 21; Said heat radiation chassis 21 is fixedly connected and heat loss through conduction with said radiating shell 2; Be specially between said heat radiation chassis 21 and the said radiating shell 2 and be fixedly connected through compression fit, said lampshade 5 is tightly connected with said radiating shell 2 mutually, in said light source board assembly 4 is surrounded on; Fix sealing through fluid sealant between said lampshade 5 and the said radiating shell 2; Said insulating element comprises insulation bucket 31 and insulating lid 32, and the surfaces externally and internally of said radiating shell 2 is the light face, is not provided with louvre and heat radiation rib; The aluminium manufacturings are adopted on said radiating shell 2, said heat radiation chassis 21; The model of said lamp holder 1 is E27, and the Lamp cup model of said LED lamp is A60, can certainly be other Lamp cup models.

Embodiment two:

Like Fig. 3, shown in Figure 4, the LED lamp of present embodiment and the difference part of embodiment one are: the model of the said lamp holder 1 of present embodiment is GU10, and its Lamp cup model is PAR16; Therefore the space of its enclosure interior is less; Said insulating element is a highland barley paper, and to reduce the space hold of said insulating element, present embodiment does not need the lampshade 5 of main its protective action of embodiment one; The extra reflector 6 that comprises; Said reflector 6 is corresponding with the LED position of said light source board assembly 4, so that led light source is carried out luminous intensity distribution, realizes the spotlight effect of shot-light.

The utility model is made ways of connecting again through said radiating shell 2 was opened with said heat radiation chassis in 21 minutes; Its wall thickness of heat-dissipating casing that adopts spinning or punching press or drawing process to process can reduce than existing radiating shell; And method is easy; The later stage assembling is easy, so the utility model cost is low, in light weight, easily manufactured.

The utility model can be widely used in the LED lighting field.
