Description

The high-power LED light source lamp cup assembly that is used for the quick conductive heat radiation of bulkhead lamp capable

Technical field

The utility model relates to the lamp lighting technical field, is a kind of reflectoscope cup assembly that is applied to can carry out the high power LED semiconductor light source in the bulkhead lamp capable quick conductive heat radiation specifically.

Background technology

The characteristics that the high power LED semiconductor light source has energy-saving and environmental protection, a long service life are described as the light source of 21st century, but in actual applying, must resolve its heat dissipation problem when luminous, otherwise will reduce because of untimely too fast its luminous efficiency that makes of light decay that causes of dispelling the heat, thereby influence is applied.In bulkhead lamp capable the high power LED semiconductor light source being carried out quick heat radiating generally is be placed in bilateral at the bottom of the aluminium matter reflection Lamp cup of the metal conducting strip of great power LED self band and a small circular aluminium flake, with rivet or screw they is connected together and carries out quick heat radiating.Be placed on the circuit board that also has great power LED of reflection Lamp cup bottom simultaneously, this disc circuit board diameter is less, the secondary light source of several low-power LEDs will be installed above, the circuit of also will arranging, and will be by outwards drawing 2-6 light source pin at the bottom of the cup, add above-mentioned 2 rivets or 2 screws, light source pin and heat radiating metal all need the insulation, they all influence the high power LED semiconductor light source and carry out quick heat radiating.And this Lamp cup structure complex manufacturing, the poor reliability of carrying out the quick conductive heat radiation, production cost is also bigger.

The utility model content

Above-mentioned deficiency at prior art, the technical problems to be solved in the utility model provides a kind of high-power LED light source lamp cup assembly that is used for the quick conductive heat radiation of bulkhead lamp capable, solve the heat dissipation problem in the high power LED semiconductor light source luminescent reliably, simplify production technology, reduce production costs.

The technical solution of the utility model is: the high-power LED light source lamp cup assembly that is used for the quick conductive heat radiation of bulkhead lamp capable contains the reflection Lamp cup of aluminium matter, the circuit board of be welded high-power LED light source and electronic component.At aluminium matter reflection circumference place, Lamp cup bottom surface by punching, draw, bending, technology such as press form one or more crotch that presses, aluminium matter reflection Lamp cup bottom surface central authorities are provided with boss upwards by drawing, the circuit board of high-power LED light source and electronic component of being welded directly presses by the crotch that presses and is fixed on aluminium matter reflection Lamp cup bottom, the metal heat-conducting plate of high-power LED light source bottom surface closely contacts with the upper surface of the boss of reflection Lamp cup bottom, thereby realizes the quick conductive heat radiation.Central authorities have through hole at boss, fill with conduction estersil in the cavity between the circular depressed of boss bottom surface, through hole and the barrier film, and the metal heat-conducting plate with great power LED ' light source bottom surface closely contacts conduction estersil in the through hole.The outlet opening of drawing the bottom surface setting of the logical peraluminous reflection of winding displacement Lamp cup that is welded on circuit board is drawn.

The utility model is reasonable in design, and is simple in structure, implements to have guaranteed the quick heat radiating of high-power LED light source, and simplified production technology easily, saved production cost.

Description of drawings

Accompanying drawing 1 is the utility model one example structure schematic diagram;

Accompanying drawing 2 is right TV structure schematic diagrames of accompanying drawing 1.

Accompanying drawing acceptance of the bid keep the score state as follows: 1-reflects Lamp cup; 2-rivet clasp crotch; The 3-through hole; The 4-circular depressed; The 5-circuit board; The 6-high-power LED light source; 7-metal heat-conducting plate; 8-outlet opening; 9-draws winding displacement; 10-low-power LED light source; The 11-barrier film; The 12-boss.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.As shown in Figure 1, the shape of Lamp cup 1 such as cup do not have unnecessary optional feature on it, and this structure of Lamp cup helps heat conduction and heat radiation.Its bottom surface is provided with boss 12 upwards by drawing, the bottom surface of boss 12 forms a circular depressed 4, high-power LED light source 6 is welded on the central authorities of circuit board 5, these circuit board 5 direct rivet clasps are in reflection Lamp cup 1 bottom, circuit board 5 presses fixing by the crotch that presses, the crotch that presses of fixing circuit board 5 at aluminium matter reflection circumference place, Lamp cup 1 bottom surface by punching, draw, bending, technology such as press form, adopt this technology can make need not be unnecessary on the Lamp cup fixture, guarantee the radiating efficiency of Lamp cup.The metal conducting strip 7 of high-power LED light source 6 self band directly contacts with boss 12 upper surfaces on the reflection Lamp cup 1, and the heat that makes high-power LED light source 6 is apace by reflecting Lamp cup 1 heat conduction and heat radiation.As shown in Figure 1, for the novel structure that makes full use of aluminium matter reflection Lamp cup 1 makes it guarantee quick heat radiating, on the boss 12 of reflection Lamp cup 1 bottom, have a small through hole 3, in the cavity of the oblate cylinder that circular depressed 4 and through hole 3 forms, fill with conduction estersil, with barrier film 11 conduction estersil is sealed again.By such structure, the heat that high-power LED light source 6 produces when luminous will by metal heat-conducting plate 7 and the conduction estersil that injects rapidly, effectively, conduction reliably gives on the aluminium matter reflection Lamp cup 1 and dispels the heat.Low-power LED light source 10 is arranged on the circuit board 5, also is provided with an outlet opening 8 in the bottom surface of reflection Lamp cup 1, and the winding displacement 9 of drawing that is welded on circuit board 5 leads to outside the reflection Lamp cup 1 by outlet opening 8.
