High power semiconductor lighting lamp

Technical field

The utility model relates to a kind of semi-conductor lighting lamp, particularly a kind of high power semiconductor lighting lamp.

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 room lighting.

Great power LED is a direction of LED industry future development, but great power LED is had relatively high expectations to heat dissipation technology, the power of led module is big more, the heat flow density of its chip is just high more, environment temperature reaches certain limit will very fast generation light decay, directly cause the decline in LED life-span, the temperature of led chip sharply rises and damages led chip when the effect of radiator is bad, has only the heat dissipation technology that solves great power LED, delay the light decay of LED to greatest extent, the application of the large-area popularization great power LED of ability.

At present, the heat radiation of high-power LED module is adopted plate shaped extrusion section bar electronic radiation device mostly or is adopted aluminium ingot Digit Control Machine Tool processing heat radiator.The geometry of the electronic radiation device of this structure is fixing, and volume is big, does not have good heat dissipation channel, and heat-sinking capability is relatively poor and comparatively fast produce light decay, directly causes the decline in LED life-span.Adopt the radiator of aluminium ingot Digit Control Machine Tool processing, its development cost are very high.

Summary of the invention

Fixing for the geometry that solves the electronic radiation device, volume is big, and the LED radiating effect is relatively poor and be not suitable for the special project heat radiation of led module, and the utility model provides a kind of high power semiconductor lighting lamp.

The technical scheme that its technical problem that solves the utility model adopts is: comprise support, LED drive plate, radiator group and one group of led module, this radiator group is pieced together by several upright post type radiators and connection strap, and the LED bolt that constitutes one with led module passes on the leghole bottom surface that copper backing is fixed on upright post type radiator center; The LED drive plate is fixed on the top of support and the inside of thermal insulation board, and thermal insulation board and support fix, and has fairlead and louvre on support, and support and heat transfer film perforation fix, and the LED drive plate is electrically connected with led module.

Described upright post type radiator is to constitute one by upright post type heat carrier, heat transfer sheet and fin; In the upright post type heat carrier, have leghole and LED fixing hole, and at the bottom of the leghole, filled and led up the copper stopper; Be provided with fin and heat transfer sheet around the upright post type heat carrier, the latter end of heat transfer sheet is provided with the heat transfer film perforation, and the both sides of its heat transfer sheet are provided with fin.

The invention has the beneficial effects as follows, the structure that this direction that makes progress along thermal current is arranged radiated rib is compared with traditional plate shaped electronic radiation device, its remarkable advantage is, heat in the led module is absorbed heat fast by copper backing with superpower heat absorption capacity or copper stopper, again by heat absorption, the heat radiation upright post type heat carrier of balanced aluminium matter is conducted heat on heat transfer sheet and the fin, these heats and surrounding air are carried out heat exchange, just can increase the coefficient of heat transfer, can reduce the temperature difference between radiator and the surrounding air, with the temperature that reduces to greatest extent in the led module, reduce the light decay of led module, reach the purpose that improves the led module life-span; Simultaneously because of having adopted the upright post type radiator mode of piecing together to realize high power semiconductor lighting lamp, secondly advantage is, the upright post type radiator can be with being squeezed into section bar, can cut use, compact conformation, improved the heat-sinking capability in space towards periphery, can satisfy the exploitation street lamp, hang multiple high power or other semiconductor lamps such as lamp, ceiling embedded lamp.
