Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
The Down lamp 100 of first embodiment of the invention, please refer to Fig. 1 to Fig. 2.
Please refer to Fig. 2 and Fig. 3, a kind of Down lamp 100 mainly comprises LED light source 10, radiator 20 and power supply module 30.This LED light source 10 is arranged on this radiator 20, and this radiator 20 is made up of conductive material.The structure that this radiator 20 is separated for left and right, comprises left radiating piece 22 and right radiating piece 21, and this LED light source 10 respectively radiating piece left with this 22 and this right radiating piece 21 is formed and is electrically connected.This power supply module 30 is for powering to this LED light source 10, and this power supply module 30 respectively radiating piece 22 left with this and right radiating piece 21 is electrically connected.
This radiator 20 is overall cup-shaped.Preferably, this LED light source 10 is arranged on the center bottom this radiator 20, and this radiator 20 forms left radiating piece 22 and the right radiating piece 21 of left and right separation along axis segmentation.This radiator 20 is provided with reflecting surface towards the surface of this LED light source 10, and this reflecting surface is for the light that converges this LED light source 10 and send and this light is launched towards the opening part of this radiator 20.
Please refer to Fig. 1, Fig. 2 and Fig. 3, also comprise insulation shell 40, this radiator 20 is fixed in this insulation shell 40.This insulation shell 40 is the cup-shaped matched with this radiator 20.This insulation shell 40 inwall is provided with buckle 41, and this radiator 20 snaps in this insulation shell 40, and is pressed in insulation shell 40 by this buckle 41.This insulation shell 40 inwall is also provided with rib 42, this rib 42 by left radiating piece 22 and right radiating piece 21 separated.
Please refer to Fig. 2 and Fig. 3, this power supply module 30 comprises two electrode terminals 31, and these two electrode terminals 31 are separately positioned on the bottom of this left radiating piece 22 and this right radiating piece 21, and radiating piece 22 left with this and this right radiating piece 21 flexibly abut respectively.Preferably, this insulation shell 40 is provided with two through holes, and these two electrode terminals 31 are each passed through these two through holes and flexibly abut with this left radiating piece 22 and this right radiating piece 21.
Please refer to Fig. 2 and Fig. 3, this LED light source 10 is flip LED chips, this LED light source 10 is provided with electric contact, and the left radiating piece 22 of this radiator 20 and right radiating piece 21 are corresponding is respectively provided with electric contact, and this electric contact is pressed on this electric contact and forms electrical connection.
Also comprise fixture 60, this LED light source 10 is fixed on this radiator 20 by fixture 60, and is fixed on this insulation shell 40 by this radiator 20 by this fixture 60.This fixture 60 comprises fixed head 62 and rivet 61, and this fixed head 62 is pressed on radiator 20 and LED light source 10.This rivet 61 is fixed on insulation shell 40 through fixed head 62 and radiator 20, radiator 20 and LED light source 10 is fixed.
Please refer to Fig. 1, Fig. 2 and Fig. 3, also include power pack 50 and lens 70, this power pack 50 spiral-lock is at the bottom of this insulation shell 40 or this power pack 50, and this power supply module 30 is arranged in this power pack 50.These lens 70 are arranged on directly over this LED light source 10.
Because this radiator 20 is fixed in this insulation shell 40 by having certain flexible buckle 41, therefore this radiator 20 can firmly be fixed in this insulation shell 40, difficult drop-off.The rib 42 passed through on insulation shell 40 due to this left radiating piece 22 and right radiating piece 21 is separated, therefore effectively avoid left radiating piece 22 and right radiating piece 21 because play or the reason such as to rock and produce electrical contact, ensure that left radiating piece 22 is connected with the normal electrical of right radiating piece 21.Because radiator 20 is overall cup-shaped, makes radiator 20 also have larger area wall of cup except bottom, increase area of dissipation greatly, improve radiating effect.Because this insulation shell 40 is the cup-shaped matched with this radiator 20.Therefore the heat that this LED light source 10 produces is delivered to this radiator 20, and then this radiator 20 can the transferring heat on insulation shell 40 of fast speed, and heat is delivered to the external world the most at last, has good radiating effect.Due to this radiator 20 for conductive material is made, LED light source 10 and power supply module 30 can be formed with this radiator 20 and be electrically connected, therefore without the need to arranging light source board structure.Because this radiator 20 is provided with reflecting surface towards the surface of this LED light source 10, the light that this LED light source 10 is sent can converge and this light is launched towards the opening part of this radiator 20.
This Down lamp 100 operationally, left radiating piece 22 and right radiating piece 21 is formed because this radiator about 20 is separated, and this left radiating piece 22 and right radiating piece 21 are formed with power supply module 30 respectively and be electrically connected, left radiating piece 22 and right radiating piece 21 are also formed with LED light source 10 respectively and are electrically connected simultaneously.What change this LED light source 10 supplies electrically connected method, and the integrally-built optimization of changing into of this method of attachment serves very crucial effect.On the one hand, this electric connection mode to be formed with this radiator 20 by the terminal on power supply module 30 and flexibly abuts, and can form electrical connection.Light source board is compared to existing technology formed with the terminal of power supply module 30 and is electrically connected, and eliminates and needs at light source board arranging the operation of female terminal by terminal.Greatly simplify electric connection structure, and save cost; On the other hand, this LED light source 10 to be formed with the electric contact on this radiator 20 by electric contact and is electrically connected, and only needs this LED light source 10 to withhold on this radiator 20 during installation.Compared to existing technology, LED light source 10 is welded on structure light source board being formed electrical connection, eliminates welding procedure, and directly avoid because the welding process LED chip that can cause or light source board scrap problem.Simplify production technology greatly.
In sum, radiator 20 by adopting the radiator 20 of conductive material, and is arranged to the structure of left and right separation by Down lamp 100.This LED light source 10 is set directly to be formed on this radiator 20 and with this radiator 20 and is electrically connected.Meanwhile, arrange power supply module 30 to be formed with this radiator 20 and be electrically connected.Compared with prior art eliminate the element of light source substrate, significantly simplify the structure of Down lamp 100.Form electrical connection by radiator 20 simultaneously, on the basis being embodied as LED light source 10 power supply, optimize electric connection structure.Thus overall structure is simple, advantage such as reduction production cost and ease of assembly dismounting etc. to make this Down lamp 100 have.
Understandable, this power pack 50 is mainly used in placing light source assembly and for installing for forming with external power source the assembly be electrically connected.Therefore, when this power pack 50 can function as described above, this power pack 50 may not be the structure in embodiment.As the independent structure that this power pack 50 can not be in embodiment, then spiral-lock is on this insulation shell 40, also can be and the integrated structure of this insulation shell 40.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
