Abstract
The utility model belongs to the field of LED (light-emitting diode) light fitting, and particularly relates to LED light fitting which has good heat radiation effect and can effectively control the temperature rise of an LED light emitting sources. The LED light fitting comprises a bottom plate, wherein a lamp shade playing a sealing protective action is arranged on the bottom plate. The LED light fitting is characterized in that a mounting plate with an arch-shaped section and located in the lamp shade is arranged on the bottom plate, multiple LED light emitting sources are arranged on the external surface of the mounting plate, and multiple radiating fins are arranged on the internal surface of the mounting plate. According to the utility model, the structure of an LED fixing plate is improved and a forced cooling device is enlarged, so that the heat radiation effect is improved, the temperature rise of the LED light emitting sources is effectively controlled, and the temperature rise problem of the LED light emitting sources is effectively solved.
Description
Technical field
The utility model belongs to the LED field of light fittings, and particularly a kind of good heat dissipation effect can effectively be controlled the LED light fixture of LED light emitting source temperature rise.
Background technology
Development and maturation along with the LED technology; The performance indications of LED increase substantially day by day, and at present, the light efficiency of white light LEDs has has met or exceeded the light efficiency level of ordinary incandescent lamp; Luminous flux is also increasing significantly, makes LED obtain using widely at lighting field.LED compares with the energy-saving lighting lamp that general photo-voltaic power supply is used, have the life-span long, heating is low, not fragile, power consumption is little and more energy-conservation outstanding advantage, people it be described as 21 century replace fluorescent lamps and incandescent lamp the 4th generation lighting source.
The core luminous component of led chip is the PN junction that has P type and N-type semiconductor to constitute, and when the forward current PN junction of flowing through, the heat generation loss makes the interface produce temperature rise; Gather heat, as effectively not dispelling the heat, the too high meeting of temperature causes led chip generation light decay effect; The luminous intensity that is LED reduces, near room temperature, and 1 ℃ of the every rising of temperature; The luminous intensity of led chip also can correspondingly reduce about 1%, and must taking effectively, heat radiation solves the light decay problem.
Summary of the invention
To above-mentioned technical problem; The utility model provides a kind of and increases forced cooling device through the structure of LED fixed head is improved, and has improved radiating effect; Thereby effectively control the temperature rise of LED light emitting source, effectively solved the problem of LED light emitting source temperature rise.
The utility model is realized through following technical scheme:
The LED light fixture; It comprises base plate; Base plate has been provided with the lampshade of seal protection effect; It is characterized in that: described base plate is provided with a cross section and is arch and is positioned at the inner installing plate of lampshade, and the outer surface of described installing plate is provided with a plurality of LED light emitting sources, and the inner surface of installing plate is provided with a plurality of fin.
Described installing plate is semielliptical shape.
Described installing plate is hemispherical.
Described base plate is provided with fresh air inlet and exhaust vent, and the base plate that described fresh air inlet goes out is provided with a fan.
In sum, the utility model improves through the structure to the installing plate of LED light emitting source, and at the inner surface of installing plate fin is set; Increased area of dissipation, improved radiating effect, simultaneously fan through setting up; Improve the flowing velocity of installing plate ambient air; Improve radiating rate with this, effectively controlled the problem of temperature rise of LED light emitting source by the way, improved the light efficiency of LED light fixture.
