Abstract

The utility model discloses a polygonal LED lamp bulb applicable to the energy-saving modification of Chinese style lamps. As a street-illuminating and landscape-decorating lamp, the Chinese style lamp is widely applied in the illumination of public accommodations such as urban main streets, parks and squares. Currently, the light source adopted by the Chinese style lamp is a high-voltage sodium lamp, the power is high, and plus the auxiliary power consumption of a power supply and a starter, the electricity consumption is high. According to the characteristic of the small caliber of the lampshade of the Chinese style lamp, the utility model designs the LED lamp bulb which adopts the LED technology to substitute the high-voltage sodium lamp adopted by the Chinese style lamp. The LED lamp bulb has the following characteristics: LEDs grouped in the shape of a polygon are adopted to arrange light; the LED lamp bulb is provided with an independent constant-current control power supply; a screw socket connector of the LED lamp bulb is matched with the prior high-voltage sodium lamp socket of the Chinese style lamp; exchange is convenient; and under the circumstance of equivalent light effect, the LED lamp bulb can save energy by more than 60 percent compared with the high-voltage sodium lamp adopted by the Chinese style lamp.

Description

Be applicable to the transformable polygonal LED lamp holder of Chinese Lantern Festival

Technical field:

The utility model relates to a kind of transformable polygonal LED lamp holder of Chinese Lantern Festival that is applicable to.

Background technology:

In colourfully decorated lantern as the hold concurrently light fixture of landscape ornamental of road lighting, communal facility illuminations (big and medium-sized cities and travelling scenery district consumption are many especially) such as city main trunk road and park plaza have been widely used in, middle colourfully decorated lantern mostly is many lamps combinations, promptly combine by 6,8,19 light fixtures that do not wait on the bar lamp, its light source adopts high-pressure mercury lamp, power is many with 110WP, adds the auxiliary power consumption of power supply and starter, and its power consumption is very large.Moreover in the high-pressure sodium bulb life-span short (light decay is serious, and 1-2 will change once), useless bulb also can pollute environment, and these all are the technological deficiencies that middle colourfully decorated lantern exists.Along with development and national economy, country advocates and sets up the environment-friendly and energy-efficient city, thereby the reducing energy consumption of middle colourfully decorated lantern has been imperative, extremely urgent.The LED light fixture is since coming out, and technological progress is quite fast, the outstanding advantage of its luminous efficiency height, long service life by common people cognition, we can say that it is the most rising illuminations of 21st century.Though high-pressure mercury lamp also belongs to energy-conserving light source, to compare with the LED light fixture of approximate light efficiency, the comparable again high-pressure mercury lamp of LED is energy-conservation more than 60%.It is too numerous to enumerate that the LED of indoor and outdoor lighting light fixture employing at present designs, yet middle colourfully decorated lantern has been reached a conclusion after weighing a matter since the generation, the light source of continuing to use always is high-pressure mercury lamp, because its lampshade bore space is limited, so the high-pressure mercury lamp that colourfully decorated lantern is continued to use in the replacement of still unmanned application LED technology.

Summary of the invention:

The utility model just provides a kind of high-pressure mercury lamp that is applicable to that colourfully decorated lantern is continued to use at present in the transformable polygonal LED lamp holder replacement of Chinese Lantern Festival.It is made up of led module, constant current control power supply and the screw socket connector of lamp body polygonal section bar, use in groups.The periphery of the polygonal section bar of lamp body is evenly equipped with the installation interface of the led module that uses in groups, and inside and outside heat abstractor.The bottom of the polygonal section bar of lamp body and constant current control power supply of the present utility model are connected to each other, the input of constant current control power supply is connected with the both positive and negative polarity of screw socket connector, the lamp socket of the bore of screw socket connector and the original high-pressure mercury lamp of middle colourfully decorated lantern is complementary, thereby can be in original exchanges on the high-pressure mercury lamp lamp socket of colourfully decorated lantern.Constant current control power supply of the present utility model is to design according to the required voltage of led module, the electric current that use in groups, and its output and each led module also connect or contact.In the middle of after colourfully decorated lantern night illumination send electricity, the utility model promptly can send the warm white of high brightness, its colour rendering is superior to the colour rendering of high-pressure mercury lamp far away, with the situation of the equal light efficiency of high-pressure mercury lamp under, its economize on electricity obvious effective rate more can be up to more than 60%.

Because the operating temperature of LED directly influences luminous efficiency and the service life of LED, the utility model has adopted following technical scheme in design:

1. designed inside and outside heat abstractor on the polygonal section bar of lamp body, to ensure that the LED work calories is able to abundant diffusion, its outside can be selected polygonals such as quadrangle, hexagon, octagonal for use, and uniform radiating fin, its inboard is also designed uniform fin n, and the design maximum diameter of lamp body should be less than the interior bore of Chinese lampshade.

2.LED the installation interface of the aluminium base of module and lamp body section bar interconnects part, adopts the high heat conductivity gap filling material that contains nano silver wire to carry out calking, thereby increases substantially the coefficient of heat conduction therebetween;

3. for promoting the thermal diffusion of heat abstractor in the lamp body section bar, the utility model has designed the circulation pore that makes progress in the lower end of constant current control power supply part, to form the passage of lamp body internal heat to the cocycle diffusion.
