Background technology

LED is a kind of novel energy-conserving light source, with its high light efficiency, the long-life, the advantage fast fetching such as heat radiation is low generation the Ying of a lot of conventional light source Yong the Collar territory, the power savings advantages of Qi Shi xian work of You, and non-maintaining absolute predominance of long-life rapid Cover each field of throwing light on; Field at lamp affixed to the ceiling also is generalizable.

At present, the LED lamp affixed to the ceiling in market, adopts following way conventionally:

Use the light fixture of traditional HID lamp or fluorescent lamp, the space of placing the electronic devices and components such as ballast, trigger on original chassis is used for placing LED driver, LED and optical module thereof are together fixed in the attached heat sinks with heat conduction and heat radiation, pass through again additional radiator to base Inner portion space heat elimination, then pass through outwards loose Hot of base wall.This structure is because lamp body is usingd traditional HID lamp or fluorescent lamp as light source design, the light source of conventional lamp itself can not produce harmful effect due to the rising of temperature, therefore there is no the enough external cooling surface areas of design deliberately, and one of most important condition of application of LED is exactly heat radiation, the temperature of LED need to be controlled in the scope that meets the normal work of LED, otherwise can cause LED serious because of overheated light decay, even seriously shorten service life.

Summary of the invention

For overcoming the deficiencies in the prior art, the utility model provides a kind of convenience that retains traditional lamp affixed to the ceiling fixed installation sector, facilitates user installation, retains Novel LED wall lamp traditional wall lamp formation skeleton, that heat dispersion is good simultaneously.

In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:

A kind of high-power LED ceiling lamp, comprise lampshade on base, fastening and base, be arranged at installing plate and LED light source and LED power supply in base, described base is the semi-surrounding shape of indent, and described installing plate is arranged in base and forms a cavity volume with base end face; Described LED power supply is fixed in cavity volume, and described LED light source is mounted on installing plate; The finishing panel that the base side at described cavity volume two ends is demountable structure, is provided with sealing strip between finishing panel and base; On described chassis outer side face and finishing panel, be equipped with fin; Fin and installing plate on described base and base are formed in one.

The bottom surface of described base is provided with inhales top installing hole, and described lamp affixed to the ceiling is fixed on ceiling by installing hole.

The fastening place of described base and lampshade is provided with sealing strip.

High-power LED ceiling lamp global shape provided by the utility model is similar to traditional structure of ceiling-mounted lamp, adopts tradition to inhale top fixed structure, facilitates user to change; The installing plate of LED light source and base and the fin structure that is formed in one, and the area of installing plate is enough large, has guaranteed heat conducting efficiency, and lamp affixed to the ceiling temperature is maintained in normal temperature range; The finishing panel that the cavity volume two ends that installing plate and base form are demountable structure, facilitates the integrated die-casting moulding of base integral body.
