Abstract

A light emitting diode (LED) indoor floodlight combined with a lampshade to dissipate heat is composed of a lamp holder, a plastic adapter, a lamp cap, an LED light source module, a driving power source module and a light-transmitting protection cup shade, wherein the lampshade is in an inverted hopper shape, radiating fins which are evenly distributed in a radial mode are arranged on the back face of the lampshade, a column body is arranged in the endocentric center of the radiating fins, threaded steps which are in butt joint with the plastic adapter (2) are arranged on the periphery of the end face of the column body, a wire through hole is reserved in the center of the column body, a platform for installation of the LED light source module (4) is arranged in the center of the front face of the lampshade, convex reinforced ribs used for installation of the light-transmitting protection cup shade (6) are reserved on the periphery of the platform, and the inner walls of the convex reinforced ribs are flat. Through the integrated design of the lamp holder, the lampshade and the radiating fins, the lampshade also serves as a part for radiation, a perfect radiating system is formed, the lampshade is enabled to play the double functions, accordingly a radiating effect of the floodlight is improved, power application can be improved to a considerable extent, and the LED indoor floodlight is high in practicability.

Description

A kind of LED indoor illumination in conjunction with the lampshade heat radiation

Technical field

The utility model belongs to the electric lighting technical field, relates to a kind of LED indoor illumination in conjunction with the lampshade heat radiation.

Background technology

At present, indoor LED illuminating lamp nearly all is to adopt the profile similar to former incandescent lamp bulb, so its radiating module is also with the constraint of its profile, thereby has limited the high-power applications of LED indoor illumination.In fact, the environment for use of indoor LED illuminating lamp is with outdoor different, and whether reasonable the heat dissipation design of LED light fixture is also is the effect of the directly whole light fixture of influence and the key factor in life-span; So, if the layout of radiating fin is not considered occupation mode and the environment for use of light fixture well, with further application, the especially application of high power room lighting of the indoor LED illuminating lamp of restriction.

Summary of the invention

The purpose of this utility model is to provide a kind of LED indoor illumination in conjunction with the lampshade heat radiation, provides a new solution to improve above-mentioned existing problem.

For achieving the above object, solution of the present utility model is:

A kind of LED indoor illumination in conjunction with the lampshade heat radiation is made up of lamp socket, plastic cement transit joint, lamp holder, led light source module, driving power module and printing opacity protection cup cover.

Described lamp socket is lampshade and the radiating fin unitary member together that forms with the disposable die casting of aluminum material; lampshade is inverted funnel-form; the back side of lampshade is for being radial equally distributed radiating fin; the entad central authorities of radiating fin are a cylinder; cylinder end face periphery has the screw thread step that docks with the plastic cement transit joint; the center of cylinder is reserved with threading hole; the positive central authorities of lampshade are for installing the platform of led light source module; periphery at this platform is reserved with the raised ribs that printing opacity protection cup cover is installed, and the inwall of muscle rib is smooth.

Described plastic cement transit joint is the natural transition external member that disposable injection molded little tube circle changes big tube circle, little tube circle end periphery is reserved with and docks supporting step with lamp holder, the lamp holder riveted is on this step, the adaptive screw thread of Zhou Youyu lamp socket butt joint in the big tube circle opening is tightened on during installation on the step of cylinder end face periphery at lamp socket back.

Described led light source module is integrated area source, is installed in screw on the platform in lampshade front of lamp socket.

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

Described driving power module becomes the pressure-stabilizing constant flow module of low-voltage dc power supply for the high-voltage ac power transformation, be installed on the cylinder end face of the lamp socket back side is the inside of lamp holder and plastic cement transit joint, high voltage source inlet wire two contacts direct and lamp holder weld, and the dc source output line passes reservation fairlead and the led light source module overlap joint of lamp socket.

Like this, the cylinder of the heat energy that is produced by led chip by the lamp socket center absorbs behind the samming conduction again and gives lampshade and the radiating fin of unfolding, and lampshade and radiating fin are finished heat exchanging process fully exposing under the environmental condition Natural Heat Convection by air.

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

1, by lamp socket, lampshade and radiating fin integrated design, lampshade also as the heat radiation a part, constituted a more perfect heat radiation system, make lampshade play dual effect, thereby improved the radiating effect of light fixture, can improve power application to a great extent, thereby have more practicality.

2, simple in structure, good looking appearance, generous, nature, coordination.

The specific embodiment

Please refer to Fig. 1, Fig. 2, Fig. 3, the utility model is made up of lamp socket 1, plastic cement transit joint 2, lamp holder 3, led light source module 4, driving power module 5 and printing opacity protection cup cover 6.

Lamp holder 3 riveteds are on the reservation step of plastic cement transit joint 2 little tube circle end peripheries, and the big tube of plastic cement transit joint 2 encloses on the screw thread step of the cylinder end face periphery that is tightened on the lamp socket back; The rim of a cup of printing opacity protection cup cover 6 squeezes the inwall of the raised ribs that is embedded in lamp socket 1 front; It is the inside of lamp holder 3 and plastic cement transit joint 2 that driving power module 5 is installed on lamp socket 1 back side cylinder end face, high voltage source inlet wire two contacts direct and lamp holder 3 weld, and the dc source output line passes reservation threading hole and led light source module 4 overlap joints of lamp socket 1.
