Description

High-power LED ceiling lamp
Technical field
The present invention relates to a kind of semiconductor lamp, especially with between power-supply controller of electric and the ring-like lamp housing inboard, with a kind of high-power LED ceiling lamp of air insulated.
Background technology
The semi-conductor electricity light source is a kind of electric light source that does not have filament, is a kind of luminescent device that directly electric energy is converted into luminous energy, is called light emitting diode, is also referred to as semiconductor lamp, the English LED that is called for short.Semiconductor lighting is considered to the new energy-conserving light source of illumination of 21 century.LED is not only energy-conservation, also have the life-span long, volume is little, safety, environmental protection, characteristics such as non-maintaining, easy to control.LED can replace conventional light source to use in a lot of places, and the speed of LED replacement traditional lighting light source has been quickened in the particularly appearance of great power LED, also makes LED become real in the large-area applications of indoor and outdoor lighting.
Great power LED is very general in the outdoor lighting application in engineering, but the application in the room lighting engineering is in the elementary step, this is because the too high factor of lumen cost on the one hand, also be on the other hand because the product category of LED room lighting very little, illumination the designer suffer from and have no way of choosing, and set obstacle for the popularization of room lighting product.LED room lighting Products Development should be paid attention to, and improves luminous efficiency and luminous flux utilization rate, reduces the whole synthesis illumination cost to greatest extent.
Great power LED is a direction of LED industry future development, but great power LED has relatively high expectations to heat dissipation technology, and the power of led module is big more, and the heat flow density of its chip is just high more.The temperature of led chip sharply rises when the effect of radiator is bad, the very fast generation light decay of meeting, even damage led chip.Have only the heat dissipation technology that solves great power LED, delay the light decay of LED to greatest extent, could understand, enter more families and applied environment as present fluorescent lamp.
Because the power of single great power LED is less, brightness is lower, should not use separately.According to the demand of lighting object and luminous flux, the semiconductor lamp with several great power LED Combination Design one-tenth " secondary souce " has broad application prospects.
Summary of the invention
The technical problem to be solved in the present invention is, providing a kind of is fixed on several great power LEDs on the double ring-like lamp housing of making radiator, and and lampshade be combined into ring-like " secondary souce ", especially with between power-supply controller of electric and the ring-like lamp housing inboard with a kind of high-power LED ceiling lamp of air insulated.
For solving the problems of the technologies described above, a kind of high-power LED ceiling lamp of the present invention comprises ring-like lamp housing, lampshade, power-supply controller of electric and one group of great power LED, great power LED is fixed on the side plane of ring-like lamp housing, and is surrounded as ring-shaped light source by lampshade; Great power LED is electrically connected with power-supply controller of electric.
Be fixed with fin on the ring-like lamp housing back side that great power LED is fixed, ring-like lamp housing outside is provided with louvre, and side ring winding within it is equipped with air vent, has wire hole on ring-like lamp housing center, and is provided with fixing hole around its wire hole.
Be provided with power-supply controller of electric and sensor in the outer casing of power supply the inside, on the outer casing of power supply side, have fairlead, use the cover closure outer casing of power supply, and on its cover plate, have wire hole; Outer casing of power supply is fixed in the ring-like lamp housing in the ring in the heart, and and ring-like lamp housing between the ring with air insulated.
The invention has the beneficial effects as follows, this fin and the ringed lamp shell structure on the direction that thermal current makes progress, arranged, its remarkable advantage is, the logical peraluminous ring-like lamp housing of the heat of great power LED conducts on the fin, by the gas channel that air vent and louvre produced, the large tracts of land heat of ring-like lamp housing inside and surrounding air are carried out heat exchange again, will reduce the temperature of great power LED to greatest extent, reduce the light decay of great power LED, reach the purpose that improves the great power LED life-span;
Especially with in outer casing of power supply and the ring-like lamp housing between the ring with air insulated, can prevent that ring-like lamp housing heat from advancing one one to the electrochemical capacitor in the power-supply controller of electric and heating up and reduce its service life;
Secondly advantage is, ring-like lamp housing and fin adopt the good aluminium material of thermal conductivity, and be optional in order to multiple manufacturing process such as punching press, die casting, extruding, its compact conformation, reduce cost, can satisfy multiple high power semiconductor lighting lamp tools such as ceiling lamp affixed to the ceiling, recessed lighting fitting, suspension lamp.
