Description

The high-power recessed light fixture of a kind of LED

Technical field

The utility model relates to LED lighting device technical field, is specifically related to the high-power recessed light fixture of the good LED of a kind of radiating effect.

Background technology

Light emitting diode (LED) is after injecting certain electric current, electronics and hole continued to flow PN junction or similar with it structural plane, and carry out the diode semiconductor device of spontaneous compound generation radiant light.The LED element sends high-luminance light with low-power, and has the long life-span, therefore is considered to follow-on lighting device.

These lighting devices must have the predetermined brightness level, therefore, in order to produce the single led lighting device that utilizes the LED element, must be arranged in thick and fast on the single led lighting device by a plurality of LED bulbs that the LED element constitutes.

Under the situation of the display lamp that the LED bulb is used as individually household electrical appliance (such as TV, phone etc.), the heat that each LED bulb is produced is no problem.Yet under the situation of the LED lighting device of having arranged many LED bulbs thick and fast, the heat that is produced by each LED bulb can cause the fatal problem of LED lighting device.

Though the LED lighting device has the originally much longer life-span than existing lighting, because the great amount of heat that numerous LED bulb produces, so the LED lighting device can suffer frequent fault and short-life puzzlement.Therefore, the LED lighting device is had no option except that the LED bulb that uses lower powered LED bulb and small number.

In order to solve the problem of LED lighting device heat radiation; Present common practice is that the LED element is mounted on the metal substrate or ceramic substrate with thermal conductive resin; And be connected on the good metal material radiator of the bigger heat conductivility of surface area; Through the heat exchange of radiator and surrounding air, heat is conducted with thermal-radiating passive radiating mode.This mode needs the bigger radiator of surface area on the one hand, makes volume and weight excessive, and cost is higher, and because this radiating mode is passive heat radiation, radiating efficiency still can not satisfy the needs of the LED lighting device of high-output power and high brightness.

For this reason, people are connected radiator with fan, utilize fan to quicken flowing of radiator surrounding air, thereby the heat of radiator is taken away by air faster, make the radiating efficiency of radiator obtain lifting to a certain degree.For example, CN201020531564.5, " high-power LED tube light ", CN201020575373.9, " active heat removal LED pendent lamp ", CN201020263109.1, " active heat removal formula high-power LED lamp ", or the like.

But in LED light fixture growing and perfect today, the radiating mode of LED light fixture also needs further to improve.

The utility model content

The utility model technical problem to be solved provides the structure of the high-power recessed light fixture of a kind of LED; This structure is compared the radiator structure that radiator adds fan and is had better radiating effect; The radiator volume of LED light fixture is further reduced; Radiating efficiency further improves, and reaches the purpose of practicing thrift cost.

The utility model technical problem to be solved is achieved through following technical scheme:

The high-power recessed light fixture of a kind of LED; Comprise illumination section, the radiator portion that is connected with illumination section; The direction regulating part that is fixedly connected with radiator portion, and illumination section being used for foremost light fixture is fixed in the fixation kit on the building, said radiator portion comprises radiator and the fan that directly contacts with illumination section; Fan is fixed in the end of radiator away from illumination section

Said radiator and fan are arranged in wind scooper, and wind scooper is a penetrating ring-type cover body up and down, and an end of radiator contact illumination part exposes wind scooper, and exposed portions serve has ventilation slot.

Said direction regulating part is the bridge joint support body, and the bridge joint support body is made up of a ring bodies and the support that is fixed in ring bodies, and said ring bodies is the non-planar rings of distortion, and the support of bridge joint support body and radiator and fixation kit are fixed together.

Said Lighting Division includes the led light source that fixes with radiator, and led light source is positioned at the reflection shield bottom, and the reflection shield front end also is covered with letter out glass and face ring.

Said fixation kit comprises interior ring, is fixed with shell fragment on the interior ring, and interior ring is connected outer shroud, mounting bracket as a whole with shell fragment through screw and nut; The support and the radiator of said outer shroud and bridge joint support body fix.

The utlity model has following beneficial effect:

The utility model exposes the part of wind scooper and offers ventilation slot owing to outside radiator and fan, install wind scooper additional in the radiator lower end, fan can water conservancy diversion advances wind scooper from the wind scooper top with the light fixture outer air; Through the radiator in the wind scooper, and discharge, compare the radiator structure that does not install wind scooper additional from the ventilation slot of radiator bottom; This structure can make air more concentrate and contact with spreader surface efficiently; Effective guidance the convection current of air in this structure, accelerate distributing of radiator heat, satisfied the radiating requirements of high-power LED light source effectively; The radiator structure of the utility model is compared the radiator structure that does not install wind scooper additional of same radiating effect; The radiator volume can further reduce, or goes for more high-power LED light source, has the effect of practicing thrift cost.

The utility model only needs to realize the rotation of four direction all around with a bridge joint support body; Compare in the traditional product structure and need in two, encircle the structure that realizes four direction rotation all around; The accessory that uses reduces, thereby has reduced cost effectively, has reduced the volume of light fixture.
