Abstract

The utility model discloses a pentagonal LED module which belongs to the technical field of semiconductor devices. The pentagonal LED module comprises a shell (1) that is shaped like a pentagonal frame, a radiating sheet (2) is arranged in the middle bottom of the inner loop of the shell (1), at least two LEDs (3) are arranged on the radiating sheet (2), insulative heat-conducting cement is filled between the LEDs (3) and the radiating sheet (2), and pins (4) of the LEDs (3) are led out from the lateral wall of the shell (1). The pentagonal LED module leads two or more LEDs to be arranged in the same circular shell, thus having comparable indexes with large-power LEDs in brightness and light efficiency, and the like, and simultaneously having saved PCB space, convenient arrangement of electronic elements and good radiating effect. Dispersive LEDs that are arranged in the same module can realize mutual light distribution and save cost of lens that are required by large-power LEDs, and by the arrangement of LEDs with different colors inside the shell and the design of external circuits, mixed light with different colors can be illuminated in different time periods.

Description

Pentagon LED module

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.

The utility model content

The purpose of this utility model is to provide a kind of good heat dissipation, and layout is pentagon LED module easily.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: pentagon LED module, the housing that comprises pentagon frame shape, the inner ring central bottom of housing is provided with fin, on fin, be provided with at least two LED, be filled with thermal conductive insulation glue between LED and the fin, 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.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail, but does not constitute any restriction of the present utility model.

Fig. 1 is the stereogram of pentagon LED module;

Fig. 2 is the phantom of Fig. 1.

The specific embodiment

As depicted in figs. 1 and 2, pentagon LED module described in the utility model comprises the housing 1 of pentagon frame shape, and housing 1 is made by insulating materials.The inner ring central bottom of housing 1 is provided with fin 2, and fin 2 can be made by the good material of heat conduction such as metal, is provided with at least two LED3 on fin 2, selects 10 LED3 among the figure for use, also can be other numbers certainly.Be filled with thermal conductive insulation glue between LED3 and the fin 2, the shape of thermal conductive insulation glue and LED3 is not clearly drawn in the drawings.Ten LED3 have 20 pins, and pin 4 extracts from the sidewall of housing 1, and the power supply that is used for LED3 connects.

Claims (2)

1. pentagon LED module, it is characterized in that comprising the housing (1) of pentagon frame shape, the inner ring central bottom of housing (1) is provided with fin (2), on fin (2), be provided with at least two LED (3), be filled with thermal conductive insulation glue between LED (3) and the fin (2), the pin (4) of LED (3) extracts from the sidewall of housing (1).
