Abstract

The utility model relates to a fresh lamp. An LED fresh lamp comprises a heat dissipation lamp holder, an adapter, a lamp cap, an LED light source module, a light-transmitting protective cup cover, a plastic lampshade and a driving power module. The LED fresh lamp is mainly characterized in that the lamp holder and streamline fins are integrally designed, therefore, the heat dissipation area and heat dispersion performance of the LED fresh lamp are improved greatly, the heat dissipation effect of the LED fresh lamp is improved, and the development toward a high-power LED fresh lamp is boosted. The LED fresh lamp has the advantages of being simple in structure and attractive, elegant, natural and coordinated in appearance.

Description

The fresh lamp of LED

Technical field

[0001] the utility model belongs to the electric lighting technical field, relates to the fresh lamp of a kind of LED.

Background technology

Fresh lamp is a kind of accent light light fixture of high color rendering index (CRI), and is undistorted just as under daylight at the illuminated object under this light.At present, fresh lamp as accent light is all the sub-assembly of lampshade and bulb mostly, especially the fresh lamp of LED, be subjected to the constraint of its profile due to the LED bulb lamp, the power that can accomplish is also very limited, thereby limited the high-power applications of the fresh lamp of LED, its brightness can not be satisfied the requirement of practical application far away.

Summary of the invention

The purpose of this utility model is to provide the fresh lamp of a kind of LED, provides a new solution take its pointed structural design as improving above-mentioned existing problem, thereby is conducive to promote the further application and development of indoor LED illumination.

For achieving the above object, solution of the present utility model is: be comprised of cooling lamp holder, adapter, lamp holder, LED light source module, printing opacity protection cup cover, plastic lamp shade and driving power module.

Described cooling lamp holder is the lamp socket that forms with the disposable die casting of aluminum material and the unitary member of radiating fin one; Lamp socket is positive faces the wall and meditates for inverted funnel-form, the periphery of facing the wall and meditating in this funnel-form is the mounting platform that docks with plastic lamp shade, its central authorities are that hopper base is that the platform of LED light source module is installed, and are reserved with the raised ribs of installation printing opacity protection cup cover in the periphery of this platform, and the inwall of muscle rib is smooth; The cooling lamp holder back side is for being radial equally distributed streamlined radiating fin, and the centripetal central authorities of radiating fin are a cylinder, and the cylinder end face is the platform that docks with adapter, and the center of cylinder is reserved with threading hole.

Described adapter is the naturally transition integrated flange part that a disposable injection molded cylinder circle turns flat circle, and cylinder circle end periphery is reserved with docks supporting step with lamp holder, and the lamp holder riveted is on this step; Flat circle part is to dock adaptive flanged plate with cooling lamp holder, is arranged on screw on the cylinder platform at cooling lamp holder back.

Described lamp holder is screw socket, uses top riveting mode riveted on adapter.

Described LED light source module be colour rendering index more than 80, the COB light source of colour temperature between 3000K to 5000K is arranged on screw on the platform of lampshade positive central authorities of cooling lamp holder.

Described printing opacity protection cup cover is to be that straight tube rim of a cup, bottom are the combination of hemispheric natural transition by the disposable injection molded port of printing opacity plastic cement, and the inwall that the rim of a cup place is embedded in the raised ribs in cooling lamp holder front closely cooperates.

Described plastic lamp shade is the bowl-shape moulding of bottom drain, and its bottom drain open circumferential is corresponding with the reservation platform of the positive periphery of cooling lamp holder, and is arranged on this platform with screw;

Described driving power module is the pressure-stabilizing constant flow module that the high-voltage ac power transformation becomes low-voltage dc power supply, be installed on the lamp holder at the cooling lamp holder back side and the inside of adapter, the high voltage source inlet wire directly with two contacts welding of lamp holder, reservation threading hole and LED light source module that the dc source output line passes cooling lamp holder overlap.

Like this, the cylinder of the heat energy that is produced by LED chip by the cooling lamp holder center absorbs after samming conduction again to the radiating fin of unfolding, and radiating fin is completed heat exchanging process exposing under environmental condition the Natural Heat Convection by air.

After adopting said structure, the utlity model has following progressive advantage:

1, by the integrated design of lamp socket and streamlined radiating fin, the area of dissipation of light fixture and heat dispersion are improved greatly, thereby improved the light fixture radiating effect, be conducive to the high-power development of light fixture.

2, simple and practical, good looking appearance, generous, nature, coordination.
