Abstract

The utility model disclose an elliptic LED module with a lamp cup, comprising an insulated shell (1) of elliptic frame shape, a heat radiation slice (2) on the middle bottom of the inner ring of the shell, at least two lamp cups (5) on the heat radiation slice capable of forming a light condensation reflection surface, a LED (3) in the lamp cup wherein the conduction insulation rubber is filled in the space between the LED and the lamp cup and the pin (4) of the LED extends from the side wall of the shell. Two or more than two LEDs are set in the same circular shell with equal illumination intensity, light efficiency or the like with the large-power LED and the PCB space is saved to facilitate the arrangement of the electronic element with good heat radiation effect. The LEDs are in dispersion type arrangement in the same module to realize the mutual light distribution and the lens cost required by the large-power LED is saved and LEDs of different color are arranged in the shell and emit different mixed color at different time interval by an external circuit design. In addition, the lamp cup can condense light for the LED and increase the directivity and centrality of the LED light source, with simple structure and low cost.

Description

The oval LED module of band Lamp cup

Technical field

The utility model belongs to the technical field of semiconductor devices, is specifically related to a kind of LED module that uses light emitting diode as light source.

Background technology

The same with conventional light source, semiconductor light-emitting-diode (LED) also can produce heat during operation, and how much it depends on whole luminous efficiency.Power up outside under the energy, the radiation recombination generation electroluminescent in electronics and hole, semiconductor medium and encapsulation medium that near the light that radiates the P-N knot also need pass through wafer (chip) itself just can arrive at external world's (air).Comprehensive electric current injection efficiency, radioluminescence quantum efficiency, wafer exterior light are taken out efficient etc., finally probably have only the input electric energy of 30-40% to be converted into luminous energy, the energy of all the other 60-70% mainly transforms heat energy with the form of the lattice vibration of non-radiative compound generation.And the rising of chip temperature then can strengthen non-radiative compoundly, further slackens luminous efficiency.

LED lighting on the market is that many LED are carried out the connection in series-parallel combination now.If carry out the connection in series-parallel combination with great power LED, the light fixture heat dissipation problem is an insoluble problem of present stage; If carry out the connection in series-parallel combination with the 20mA low-power LED, the usage quantity of LED can roll up, and in limited space, also is a necessary considerable problem to the components and parts layout on the circuit board.In addition, the concentration structure of existing LED lamp also exists cost to compare problem of higher.

The utility model content

The purpose of this utility model is to provide that a kind of good heat dissipation, layout are convenient, concentration structure is simply with the oval LED module of Lamp cup.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the oval LED module of band Lamp cup, the housing that comprises insulation, housing is the oval frame shape, the inner ring central bottom of housing is provided with fin, is provided with at least two Lamp cups that can constitute the optically focused reflecting surface on fin, is provided with LED in the described Lamp cup, be filled with thermal conductive insulation glue between LED and the Lamp cup, the pin of LED extracts from the sidewall of housing.

Owing to adopted above-mentioned structure, the utlity model has following beneficial effect:

1), two even more a plurality of 3V/20mALED chip dispersed combination in same circular shell, can be suitable in indexs such as illumination, light efficiencies with great power LED, also save the PCB space simultaneously, make things convenient for the layout of electronic component;

2), the heat that produces of LED is delivered to the dew copper zone of the PCB that is installed by fin, reveals the copper zone by PCB then and distributes, and has better heat radiating effect;

3), distributing is arranged in the same module LED can realize mutual luminous intensity distribution, can save the lens cost that great power LED need be used, the LED of discharging different colours in housing, by the external circuit design, the different periods can be sent the mixed light of different colours again;

4), according to external circuit design, can take the connection in series-parallel connected mode flexibly to LED in the module;

5), Lamp cup can carry out optically focused to LED, strengthens the directionality and the centrality of led light source, it is simple in structure, cost is low.
