Description

LED multifaceted light-emitting light fixture

Technical field

The utility model belongs to lighting technical field, relates to the LED light fixture, particularly relate to a kind of can the luminous LED multifaceted light-emitting light fixture of comprehensive wide-angle.

Background technology

The corn lamp that has the multifaceted light-emitting performance in the market is to adopt the plastics pcb board to do the basis, as light source, adopts the type of drive of resistance-capacitance depressurization type of drive as power supply with low-power LED.The deficiency of its existence has: 1. adopt the plastics pcb board to do the basis, the heat that causes the lamp pearl to produce is not easy to shed, and produces the too high phenomenon of environment temperature; 2. the light decay of low-power LED own is than very fast; 3. conversion circuit adopts the resistance-capacitance depressurization type of drive, the circuit efficiency of this type of drive is low, the output voltage instability, and the electric current by LED can fluctuate along with the change of temperature, input voltage etc., fluctuating range even be higher than 20% has a strong impact on brightness uniformity and the LED life-span of LED.Because top various reasons, cause bad phenomenon such as the too fast and regular dead lamp of light fixture light decay.

Summary of the invention

The purpose of this utility model provides that a kind of efficient height, light decay are low, the LED multifaceted light-emitting light fixture of good endurance.

LED multifaceted light-emitting light fixture of the present utility model includes:

The aluminium alloy heat radiation lamp body of an abnormity, its middle part is a cavity, is provided with several mounting planes all around;

The elongated aluminium base that equates with mounting plane quantity is fixed on the aluminium alloy heat radiation lamp body mounting plane all around, and the LED paster that quantity equates is installed on each aluminium base;

A round aluminium base is fixed on the front end of aluminium alloy heat radiation lamp body, is used to seal the cavity of aluminium alloy heat radiation lamp body, and several LED pasters are installed on round aluminium base;

A lampshade is connected the upper end of aluminium alloy heat radiation lamp body, is used to compress round aluminium base;

A constant-current supply driver module is installed in the cavity at aluminium alloy heat radiation lamp body middle part;

A screw socket connector is connected the lower end of aluminium alloy heat radiation lamp body, is used for fixing screw socket.

Further, mounting plane number of the present utility model is 8, and 6 LED pasters are installed on each elongated aluminium base, and 12 LED pasters are installed on round aluminium base.

LED multifaceted light-emitting light fixture of the present utility model has used and has had aluminium alloy heat radiation lamp body a large amount of fins, that have big area of dissipation, lamp body adopts extrudate technology, and in conjunction with the higher aluminium base of heat transfer efficiency, the heat that the LED paster is produced is delivered on the lamp body fast, pass in the air fast by cross-ventilation, set up the good heat transfer system, the LED paster is worked under lower environment temperature.

LED multifaceted light-emitting light fixture of the present utility model uses and adopts constant current voltage stabilizing circuit as power module, makes the voltage at electric current by led chip and its two ends more stable, has ensured the electric light transformation efficiency of led chip effectively.

LED multifaceted light-emitting light fixture of the present utility model can be widely used in wall lamp, enclosure wall lamp, garden lamp, desk lamp, Down lamp, Mirror front lamp, lamp affixed to the ceiling, bar lamp, decoration and practical in family's light fixture, have that volume is little, cost is low, the advantage of perfect heat-dissipating, can directly replace light fixtures such as existing E27 screw-socket bulb and electricity-saving lamp fully, the life-span is longer when normal the use, light decay is slower to guarantee light fixture.
