Description
Technical field
The utility model relates to LED technical field, particularly packaged LED device in a kind of specular aluminium.
Background technology
LED refers to the encapsulation of luminescence chip.The encapsulation of LED not only requirement can protect wick, but also can printing opacity, therefore requires higher for encapsulating material.The baseplate material of LED has a variety of, and wherein copper base is the most common.Because the heat conductivility of red copper is more outstanding, in conjunction with silver plating process, thus always accept by market.The blackout but silver easily cures in high temperature environments, directly affects reflecting rate, creates light decay.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, packaged LED device in a kind of specular aluminium reasonable in design, easy to use, it adopts specular aluminium to be that substrate is combined with flexible PCB, and form LED mirror-surface aluminum base board, it is simple that it has structure, easy to make, chip is fully utilized, and solves the unsteadiness of metal material, packaged LED has the advantages such as the useful life of overlength.
For achieving the above object, the technical solution adopted in the utility model is:
Packaged LED device in a kind of specular aluminium described in the utility model, it comprises LED aluminum base plate and is arranged on the LED chip in LED aluminum base plate; Described LED aluminum base plate is made up of substrate and flexible PCB wiring board, and this flexible PCB wiring board group is pasted onto on substrate by high-temperature plastic; Described substrate is the minute surface aluminium sheet that specular aluminium is stamped to form.
Further, described minute surface aluminium sheet is provided with diaphragm.
After adopting said structure, the utility model beneficial effect is: packaged LED device in a kind of specular aluminium described in the utility model, it adopts specular aluminium to be that substrate is combined with flexible PCB, form LED mirror-surface aluminum base board, it is simple that it has structure, easy to make, and chip is fully utilized, and solving the unsteadiness of metal material, packaged LED has the advantages such as the useful life of overlength.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals:
1, substrate; 2, flexible PCB wiring board; 3, LED chip.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, packaged LED device in a kind of specular aluminium described in the utility model, it comprises LED aluminum base plate and is arranged on the LED chip 3 in LED aluminum base plate; Described LED aluminum base plate is made up of substrate 1 and flexible PCB wiring board 2, and this flexible PCB wiring board 2 groups is pasted on substrate 1 by high-temperature plastic; The minute surface aluminium sheet that described substrate 1 is stamped to form for specular aluminium.
Preferred as one of the present utility model, described minute surface aluminium sheet is provided with diaphragm.
The utility model is when making, and first passed through by the specular aluminium coiled strip of import and flatten, punch forming, form substrate, this substrate is the minute surface aluminium sheet of punch forming (as required the various shape of punching press); Then the flexible PCB (printed circuit board) adopting PET (PETG) to make is in conjunction with high-temperature plastic.Draw by the electrode of LED after sticking.Be exactly now the LED mirror-surface aluminum base board of a standard, light-emitting area can carry out arrangement packaging LED chips therebetween.Crystal-bonding adhesive in encapsulation is the white epoxy resin that special thermal conductivity is stronger, without ag material, and can not sulfide staining.
In the utility model, this department studies the specular aluminium using German import in the situation that wattage is lower by experiment, and reflectivity reaches 98%, has the superior function being not less than silver-colored reflectivity, and surface is not easily oxidized or other reactions occur make its reflectance reduction.Stable and reliable for performance.LED for low wattage is only applicable to again.In conjunction with special PET flexible PCB, also solve the problem stopping chip light emitting simultaneously.
Packaged LED device in a kind of specular aluminium described in the utility model, it adopts specular aluminium to be that substrate is combined with flexible PCB, form LED mirror-surface aluminum base board, it is simple that it has structure, easy to make, chip is fully utilized, and solves the unsteadiness of metal material, packaged LED has the advantages such as the useful life of overlength.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
