Abstract

The utility model discloses a safe light-emitting diode (LED) bulb lamp, which comprises a lamp holder. A lamp holder lining is installed on the lamp holder, a driving power supply is installed in the lamp holder lining, a radiator is installed outside the driving power supply, an LED module and a lamp cover are installed on the radiator, a shell of the radiator is made of non-conductive plastics, and metal radiating fins are inlaid in the non-conductive plastic shell. The safe LED bulb lamp adopts a mold inserting structure, and successfully solves the problem that electric shock resisting safety and heat dispersion of an LED bulb lamp cannot be compatible. A non-separation power supply with high efficiency can be selected as the driving power supply, so that an LED bulb is led to be more energy saving and higher in efficiency. The safe LED bulb lamp is simple in structure, high in cost performance, safe and reliable and quite durable and can be widely used in lighting as the LED bulb lamp which is safe and excellent in performance.

Description

A kind of safe LED bulb lamp

Technical field

The utility model relates to a kind of light fixture, particularly a kind of safe LED bulb lamp.

Background technology

Common LED bulb lamp structure is as shown in Figure 1, is made up of lampshade 1, led module 2, led module radiator 3, insulation inner casing 4, driving power 5 and lamp holder 6.

As everyone knows, led module and driving power all can generate heat because of the relation of efficient, and the temperature that heating causes rising is the main restricting factor that influences bulb life and efficient.

The structure of present common LED bulb lamp is as illustrated in fig. 1 and 2, and radiator is the metal of conduction, and on-chip power does not get an electric shock in order to ensure human body in lumen of radiator, increases a plastic inner shell at lumen of radiator.However; Because radiator is a metal; Human body still can contact with radiator in the installation or removal light fixture; Can not avoid human electric shock's risk fully, thus the lower low pressure buffer circuit of efficient in the selection of power supply, mostly adopted, and dare not the higher non-buffer circuit of efficiency of selection.

Yet adopt plastics to remove to make radiator, cause the operating temperature of power supply and led module too high, and have influence on the life-span of whole lamp because of the heat conductivility difference of plastics.

The utility model content

In order to solve above-mentioned technical problem, the purpose of the utility model provides a kind of simple in structure, LED bulb lamp that radiating effect is desirable and safe and practical.

The utility model solves the technical scheme that its technical problem adopted:

A kind of safe LED bulb lamp; Comprise lamp holder, the lamp holder liner is installed on the said lamp holder, be provided with driving power in the said lamp holder liner; Said driving power is equipped with radiator outward; Led module and lampshade are installed on the radiator, and the shell of said radiator is nonconducting plastic casing, in nonconducting plastic casing, is inlaid with metal fin.

Further as preferred embodiment, said radiator is the composite molding structure of non-conducting material coated with conductive metal.

Further as preferred embodiment, said conducting metal is copper or aluminium.

Further, fill casting glue between said driving power and the radiator as preferred embodiment.

Further, be provided with draw-in groove in the said lamp holder liner and driving power is installed in the above as preferred embodiment.

The beneficial effect of the utility model is: the utility model adopts the structure of mold insert; The electric shock-prevention safety property and the heat dispersion compatibling problem of LED bulb lamp have successfully been solved; Can the higher non-isolated power supply of efficiency of selection in the selection of driving power, make the more energy-conservation and high efficiency of LED bulb.The utility model is simple in structure, cost performance is high, safe and reliable and very durable.

The specific embodiment

With reference to Fig. 3 to Fig. 6, a kind of safe LED bulb lamp comprises lamp holder 6; On the said lamp holder 6 lamp holder liner 8 is installed; Be provided with driving power 5 in the said lamp holder liner 8, outside the said driving power 5 radiator 7 be installed, led module 2 and lampshade 1 are installed on the radiator 7; The shell of said radiator 7 is nonconducting plastic casing, in nonconducting plastic casing, is inlaid with metal fin.

This plastic casing places dark environment can send bright fluorescence after absorbing light, and this plastic casing can be transparent, and is translucent or opaque.

Further as preferred embodiment, said radiator 7 is the composite molding structure of non-conducting material coated with conductive metal.

Further as preferred embodiment, said conducting metal is copper or aluminium.

Further, fill casting glue between said driving power 5 and the radiator 7 as preferred embodiment.

Further, be provided with draw-in groove in the said lamp holder liner 8 and driving power 5 is installed in the above as preferred embodiment.

The structure of mold insert is adopted in this creation, has successfully solved the electric shock-prevention safety property and the heat dispersion compatibling problem of LED bulb lamp.Through the mode of injection mo(u)lding,, be embedded in nonconducting plastic casing heat conduction metal material rapidly; Led module is directly installed on the aluminium alloy through heat-conducting medium, integrated like this mode, (part that people's physical efficiency touches all is plastics both to have solved the security of protection against electric shock; Non-conductive); Rapidly heat is transmitted on the plastics equably through aluminium alloy again, is dispersed into again in the atmosphere, solve the problem of heat radiation.And because solved the problem of protection against electric shock from root, therefore can the higher non-isolated power supply of efficiency of selection in the selection of driving power, make the more energy-conservation and high efficiency of LED bulb.

As shown in Figure 4; The LED light emitting module is fixed on (the LED radiator is that metal is one-body molded through the injection moulding mode with the insulation plastic material) on the LED radiator through heat-conducting medium; Driving power is through the inside draw-in groove of power-supply radiator; Be fixed on power-supply radiator inside, in order to reduce the thermal-conduction resistance between driving power and the power-supply radiator, with inner heat conduction casting glue or other medium of filling of power-supply radiator.Assemble lamp holder then, form a complete LED bulb lamp.

More than be that preferable enforcement to the utility model specifies; But the utility model is created and is not limited to said embodiment; Those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
