Description

A kind of modified LED die set

[affiliated technical field]

The utility model relates to LED module technical field, relates in particular to a kind of modified LED die set.

[background technology]

Because the LED light fixture has rich color, advantages such as volume is little, energy-conservation, life-span length.Therefore, LED has extensively applied to the advertisement and identifier lamp as light source, and field ranges of application such as for example alphabetical lamp, sign board, advertising lamp box are more extensive.

Traditional LED die set mainly comprises great power LED, transparent devices, PCB circuit board, heat-radiating aluminum plate and base; Great power LED is welded on and forms the led circuit plate on the PCB circuit board; Then the led circuit plate is fixed on the heat-radiating aluminum plate; The heat-radiating aluminum plate is arranged on the base, covers and be fixed on the top of above-mentioned device again through screw with transparent devices; Though this device good heat dissipation effect, its problem are that device is too much, the production technology check causes cost high; Moreover the great power LED price is high, the generation heat is big, and the whole glazing part of LED module is inhomogeneous simultaneously, and these technical problems are present urgent problems.

[summary of the invention]

In order to solve above-mentioned existing technical problem, the utility model provides a kind of modified LED die set, has both reduced cost, has improved the distributing homogeneity of light, does not influence radiating effect again.

The utility model solves the technical scheme that its technical problem adopted: a kind of modified LED die set; It mainly comprises transparent devices, PCB assembly, lead, casting glue and double faced adhesive tape; It is characterized in that: said PCB assembly comprises LED and PCB aluminium base; Said LED is welded on the PCB aluminium base, and said transparent devices covers the PCB assembly.

As the further improvement of the utility model, said LED is middle power LED, and power LED because its price is low, greatly reduces cost as light emitting source in the employing; The heat that power LED produces simultaneously is less than great power LED, therefore heat-radiating aluminum plate and base can be set, and also can not influence radiating effect, does not promptly exert an influence the service life to LED.

As the further improvement of the utility model, said PCB aluminium base is the heat-radiating aluminum plate, and promptly PCB aluminium base and heat-radiating aluminum plate are one; Directly LED is welded on the PCB aluminium base, PCB aluminium base below no longer is provided with heat-radiating aluminum plate and base, and production technology is simple, and cost reduces.

As the further improvement of the utility model, said transparent devices inboard and the top that is positioned at LED are provided with the secondary light-distribution concave mirror, and this has not only solved the little problem of lighting angle, can improve the distributing homogeneity of light simultaneously greatly.

The described a kind of modified LED die set of the utility model, the beneficial effect of its generation is: directly LED is welded on the PCB aluminium base, need not to dispose heat-radiating aluminum plate and base, reduce cost and simplify production process simultaneously and raise the efficiency; Power LED during light source adopts, not only price is low and to produce heat few, and the heat of generation can directly outwards distribute through the PCB aluminium base, to not exerting an influence in service life of LED.

[specific embodiment]

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

The utility model provides a kind of modified LED die set, with reference to Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, mainly comprises: screw (10), transparent devices (20); Lead (30), PCB assembly (40), LED (41); PCB aluminium base (42), double faced adhesive tape (50), casting glue (60).

PCB assembly (40) comprises LED (41) and PCB aluminium base (42), and said LED (41) and lead (30) are welded on the fixed position of PCB aluminium base (42), and LED (41) is middle power LED, and this LED (41) has advantages such as price is low, high light efficiency; Said transparent devices (20) covers PCB assembly (40), uses screw (10) fixing then; Slit perfusion casting glue (60) between PCB assembly (40) and the transparent devices (20) can reach the effect of water proof and dust proof, thereby improve degree of protection, further can increase the service life; Paste double faced adhesive tape (60) at the bottom surface of PCB aluminium base (42) at last, play the effect of installing and fixing.

Transparent devices (20) inboard and be positioned at LED (41) directly over be provided with the secondary light-distribution concave mirror, this not only can solve the little problem of lighting angle, can improve the distributing homogeneity of light simultaneously greatly.

The above embodiment has only expressed the embodiment of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
