Description

A kind of combined power-type LED Lamp cup
Technical field
It is a kind of light source of main element that the utility model relates to optical semiconductor emitting diode (LED); Be specifically related to LED Lamp cup and structure thereof.
Technical background
The light emitting diode of visible light (LED) originates from the nineties in 20th century, is the expansion of ultra-high brightness LED application.Along with the appearance of ultra-bright LED, its efficient is more and more higher, and price descends gradually.Simultaneously LED have life-span length, vibration resistance, luminous efficiency height, noiseless, be not afraid of characteristics such as low temperature, no mercury pollution problem and cost performance height.The super brightness power-type LED has been expanded LED greatly and has been shown and the lighting source Application for Field at various signals.
Though led light source has above-mentioned multiple advantage, it is different fully with the form of the original conventional light source that adopts of various kinds of equipment, therefore can't directly substitute these light sources, must be the led light source design specially.Common scheme is the form that led light source is assembled into Lamp cup, and the user such as does not need to weld at work again like this, directly the LED Lamp cup is installed to and goes in the lighting apparatus to get final product, and has made things convenient for use.
The power type LED light source caloric value is bigger, therefore must carry out heat dissipation design in application.LED Lamp cup commonly used at present, the mode that the employing whole casing that has is all done with aluminum reaches better heat radiating effect, but does like this, and the shape of aluminium is comparatively complicated, and uses aluminium also many, and the processing and fabricating cost is higher, causes the product price height; The employing plastic casing that has, injection moulding one-shot forming like this, cost is low, but has ignored the heat dissipation problem of led light source, and is unfavorable to the service life and the reliability of product.
The utility model content
The purpose of this utility model provides a kind of combined power-type LED Lamp cup, and its agent structure is made of plastic casing and metal heat sink, has taken into account the cost and the heat-sinking capability of Lamp cup.
The combined power-type LED Lamp cup of the utility model mainly is made up of plastic casing, radiator, led light source and lens.Plastic casing is according to the use needs design of product, as a cup-shaped housing; Radiator then is made into bowl-shape, and its profile matches with plastic casing, can put into plastic casing, the inner shape that forms a taper bowl; Led light source is positioned on the plane of taper bowl bottom of radiator inside; Distribute in order to form suitable light, above led light source, also fix lens.At last, for protection Lamp cup internal structure, also can on plastic casing, add a transparent protective cover by opening part.
In the utility model, led light source is positioned at bowl-shape radiator, and the inner surface of radiator has reflective effect, and the light that led light source is revealed to the next door forwards reflects, and improves light utilization efficiency.Led light source closely contacts with radiator simultaneously, and the heat that led light source is produced passes away by radiator.This scheme had both improved the heat dispersion of Lamp cup, greatly reduced cost than full aluminium Lamp cup again.
Led light source can be bonded on the radiator with high-heat-conductivity glue, and also available screw is fixed on the radiator, perhaps two kinds of method combinations.
The type of lens is selected for use according to the use needs of product, makes the bright dipping of Lamp cup form required distribution effect, and art technology people can select for use or design voluntarily.
The material of plastic casing is general engineering plastics, makes of the method for injection moulding; The material of radiator is generally aluminium or copper, can make of the method for car system or mold pressing or casting.For increasing reflecting effect, also can plate the highlighted reflectance coating of one deck on the inner surface of radiator, this is the known technology of association area.
In the plastic casing, the conversion electric power that also can add led light source is converted to the required current/voltage of led light source work with external power source (as the 220V civil power), also can be changed earlier by external power source, directly provide required current/voltage then, do not have power supply in the Lamp cup to Lamp cup.This is the configuration decision according to lighting apparatus fully, also is the known contents of electronic applications personnel.
The bottom of plastic casing is provided with the interface of Lamp cup and external power source, according to the purposes of product, can arrange various interface, inserts standard interfaces such as type as screw socket, bayonet socket, pin, also can be according to equipment needs design particular interface.
Led light source in the Lamp cup can be selected different color, power, luminous flux, light intensity and encapsulated type etc. according to application need.Led light source can be the also light source of multicore sheet of single-chip, can be that monochromatic chip also can be with the synthetic chip unit of a plurality of monochromatic chipsets, so that obtain the light of required color.
The combined power-type LED Lamp cup of the utility model is of many uses, can be used as indoor, outdoor lighting, purposes such as device-specific illumination.
