Description
Technical field
The utility model relates to a kind of large-power LED light bead, particularly a kind of multi-chip LED lamp pearl.
Background technology
Great power LED as the 4th generation electric light source; Belong to typical green illumination light source; Have long, advantage such as light efficiency is high, radiationless and low-power consumption of life-span than conventional light source, will replace traditional incandescent lamp, tungsten halogen lamp and fluorescent lamp gradually becomes electric light source of new generation and is widely used in the general illumination field.
Multi-chip LED lamp pearl in the market; Comprise lamp pearl of a chip controls and two kinds of forms of lamp pearl of a plurality of chip controls; Usually each chip is laterally to place, so need bigger horizontal area, the cross-sectional area of the radiator that then adapts with it is also bigger; Make that the overall volume of LED lamp pearl is bigger, cause the manufacturing cost of whole LED packaged light source higher; In addition; LED lamp pearl is bonding and be electrically connected on the pcb board; So the heat radiation of LED lamp pearl must be earlier through pcb board, and then be communicated with radiator and carry out heat conduction, this pcb board just makes the whole LED packaged light source not only increase cost but also influence the integral insulation performance; And can see exposed solder joint on the pcb board, influenced attractive in appearance; Additionally, if LED lamp pearl damages, be difficult for usually changing or maintenance, even replacement cost is too high.
Name is called " high-power direct plug-in type light emitting diode "; The patent No. is 201010183574.9; The application for a patent for invention prospectus that open day is on October 13rd, 2010 discloses a kind of large-power LED light bead, comprises a Plastic Package cover, and this Plastic Package cover is provided with button bit; One plastic stent, this plastic stent is provided with clasp, and plastic stent was installed on the Plastic Package cover through clasp and cooperating of button bit, and plastic stent is provided with first polarity dots, second polarity dots and the 3rd polarity dots; One sheffield plate, this sheffield plate is installed on the plastic stent, and on the sheffield plate wafer is installed, and this wafer is connected with first polarity dots on the plastic stent; Two silver-plated iron plates, this two silver-plated iron plate is installed on the plastic stent, and respectively with plastic stent on second polarity dots contact with the 3rd polarity dots, second polarity dots is connected with wafer through gold thread with the 3rd polarity dots.
Can find out; Wafer is to be connected with first polarity dots on being arranged on plastic stent in this invention application; Though be mechanical connection between not concrete openly wafer and first polarity dots in the specification or be electrically connected, yet this product can be done further simplification with the saving cost.
Summary of the invention
The utility model provides a kind of direct insertion multi-chip LED lamp pearl, and a plurality of led chips are integrated in one, and realized lamp pearl of a plurality of chip controls, and lamp pearl structure is simplified more.
For achieving the above object, the utility model is taked following technical scheme:
A kind of direct insertion multi-chip LED lamp pearl comprises support, metal base, at least two led chips and at least two pins; Pin and metal base are fixed on the support, and metal base is provided with at least one led chip installed surface, also is provided with at least one radiating surface; The surface area of said led chip installed surface is less than the surface area of said radiating surface; And said led chip installed surface and said radiating surface are orthogonal or near orthogonal; Led chip is fixed on the led chip installed surface, adopts the direct conducting of lead between the led chip; Also adopt the direct conducting of lead between led chip and the electrode.
The LED lamp pearl of the utility model need not to be provided with polarity dots, can realize multi-chip light emitting.And led chip mainly is that radiating surface through metal base dispels the heat; Because the surface area of radiating surface is greater than the surface area of led chip installed surface; And radiating surface and led chip installed surface are orthogonal or near orthogonal; Even therefore the surface area of led chip installed surface is smaller, needn't worry that also LED lamp pearl temperature is too high, because the heat of LED lamp pearl can be delivered to radiator through radiating surface.Because it is smaller that the area of led chip installed surface can make, so the volume of radiator also can be smaller, thereby save manufacturing cost.In addition, such LED lamp pearl can be realized direct insertion installation, is convenient for changing the lamp pearl.
Should be noted that led chip installed surface and said radiating surface are orthogonal or approaching orthogonal, refer to and to be mutually 90 ° between led chip installed surface and the radiating surface, also can have certain angular deviation between the two.It is generally acknowledged that two angles between the face belong to two faces near mutually perpendicular situation between 60 °～90 °.
When the quantity of pin was 2, led chip can be for being electrically connected in series mode between 2 pins, or parallelly connected electric connection mode, or the series-parallel connection electric connection mode.
Cap preferably is installed on support; Cap can be light-distribution lens, controls with the lighting angle to led chip.
The utility model is simple in structure, saves polarity dots cost and radiator cost, good heat dissipation effect.And it is luminous to realize that a plurality of chips are controlled a lamp pearl.This kind LED lamp pearl is direct insertion, and maintain and replace is very convenient, and relevant cost is cheap, is beneficial to popularizing of led light source.
