Abstract

The utility model discloses a diamond LED module group with lamp cups. The LED module group comprises a diamond frame-shaped insulating housing (1); a cooling fin (2) is arranged at the bottom of the central part of an inner ring of the housing; at least two lamp cups (5) which can form light-focusing reflection surfaces are arranged on the upper surface of the cooling fin; an LED (3) is arranged in each lamp cup; a heat conductive insulation adhesive is filled between the LED and the lamp cup; and a pin (4) of the LED is guided out from the side wall of the housing. At least two LEDs are placed in the same round housing, so that indexes of the LED module group such as the illumination intensity, the luminous efficiency and the like can match those of a high-power LED; and at the same time, the LED module group saves PCB space, is convenient for the layout of an electronic element, and has good radiating effect. Dispersedly arrayed LEDs in the same module group can achieve mutual light distribution, thereby saving the cost of lenses needed by the high-power LED; as LEDs in different colors are arrayed in the housing, and an external circuit is designed, the LED module group can transmit mixed lights in different colors in different periods; and besides, the lamp cups can condense the LEDs, thereby strengthening the directivity and the concentricity of the LED power source. The LED module group has the advantages of simple structure and low cost.

Description

The rhombus LED module of band Lamp cup

Technical field

The utility model belongs to the technical field of semiconductor device, 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 electroluminescence 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 rhombus LED module of Lamp cup.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the rhombus LED module of band Lamp cup, the housing that comprises insulation, housing is the diamond 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 directivity and the centrality of led light source, it is simple in structure, cost is low.
