Abstract

The utility model discloses a light-emitting diode (LED) lamp with a built-in radiator. The LED lamp is low in cost and high in safety. The LED lamp comprises a lamp base (1), a casing (2), a driving circuit (3) and a light source panel (5) with an LED, wherein the driving circuit (3) is arranged in the casing (2). The LED lamp further comprises the radiator (4). The casing (2) is an insulation casing, and the radiator (4) is connected with the back of the light source panel (5) to carry out thermal conduction. The LED lamp with the built-in radiator is widely applied to the field of LED lighting.

Description

The LED lamp that a kind of radiator is built-in

Technical field

The utility model relates to the built-in LED lamp of a kind of radiator.

Background technology

Along with science and technology development, 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.Because the metal shell area is bigger, therefore more with material, weight is bigger, and material cost is higher; In addition,, there is the potential safety hazard of leaking electricity, perhaps possibly has the not enough possibility of creep age distance for the high-voltage LED lamp that uses civil power owing to adopt metal shell.

The utility model content

The utility model technical problem to be solved is the deficiency that overcomes prior art, provides low, the safe radiator of a kind of cost built-in LED lamp.

The technical scheme that the utility model adopted is: the utility model comprises lamp holder, housing, drive circuit, has the light source board of LED; Said drive circuit is positioned at said housing; Said LED lamp also comprises radiator; Said housing is an insulation shell, and said radiator is connected with the back side of said light source board and heat loss through conduction.

Said radiator is between said light source board and said drive circuit.

Said LED lamp also comprises lens, and said lens are connected with said housing, with said light source board ladle cover.

The sidewall of said housing is provided with louvre or heat radiation rib.

Said housing adopts plastic cement or glass manufacturing.

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 radiator, said housing is an insulation shell, and said radiator is connected with the back side of said light source board and heat loss through conduction; Through metal shell is replaced with insulation shell, save metal, weight reduction; Reduced the material cost of housing, built-in said radiator can satisfy the requirement of heat radiation, in addition; Insulation shell has improved security; Avoided the possibility of getting an electric shock, improved creep age distance, so the utility model cost is low, safe.

Fig. 3 is the section structure sketch map of the utility model embodiment.

The specific embodiment

Like Fig. 1～shown in Figure 3, the LED lamp of present embodiment comprises lamp holder 1, housing 2, drive circuit 3, radiator 4, the light source board 5 that has LED, lens 6, and said drive circuit 3 is positioned at said housing 2; Said housing 2 is insulation shells, and said housing 2 adopts the plastic cement manufacturing, can certainly adopt the glass manufacturing; Said radiator 4 is connected with the back side of said light source board 5 and heat loss through conduction, and said radiator 4 is between said light source board 5 and said drive circuit 3, and said lens 6 are connected with said housing 2; With said light source board 5 ladle covers; The sidewall of said housing 2 is provided with louvre, can certainly be provided with the heat radiation rib, and the model of said lamp holder is GU10; Certainly adopt other lamp holders, like E27 or E26 or E14 or E12 or GU5.3 or GX5.3 or GX53 or GZ5.3 or G53 or G4 etc.

The utility model is saved metal, weight reduction through metal shell is replaced with insulation shell; Reduced the material cost of housing,, built-in said radiator can satisfy the requirement of heat radiation; In addition, insulation shell has improved security, has avoided the possibility of getting an electric shock; Improved creep age distance, so the utility model cost is low, safe.

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