In the embodiment of Figure 1A and 1B, light source carrier 101,111 and circuit carrier 102,112 are directly connected to, therefore, It, can be directly in ceramic material when laying electric conductor (printed wire or the soft route) for being electrically connected LED light source module and circuit It is laid in the light source carrier 101,111 and circuit carrier 102,112 of matter, such as will directly be electrically connected LED light source module and electricity The electric conductor on road is laid in light source carrier 101,111 and circuit carrier 102,112 in the form of printed wire, alternatively, in light Groove body is opened up on source carrier 101,111 and circuit carrier 102,112 for being embedded and being electrically connected leading for LED light source module and circuit Electric line.
In this way, also can realize protection and heat dissipation to the electric conductor using ceramics as the carrier of the electric conductor.
In the embodiment of the application, the circuit and LED light source module by be printed in the light source carrier 101, 111 and circuit carrier 102,112 electric conductor be electrically connected；Alternatively, the light source carrier 101,111 and circuit carrier 102, 112 are equipped with the groove portion for accommodating the electric conductor for being electrically connected the circuit and LED light source module.
It, can be mutual between the light source carrier 101,111 and circuit carrier 102,112 in the embodiment of Figure 1A and Figure 1B It is vertically arranged, avoids circuit carrier 102,112 when being easy by external force towards circuit carrier 102,112 easily with respect to circuit Carrier 102,112 is moved and is damaged, it is further preferred that the circuit carrier 102,112 and light source carrier 101,111 it Between also settable reinforcing rib, to avoid the relative motion.
It should be noted that although the circuit carrier in above-described embodiment shows only one, in fact, the circuit Carrier can be multiple, and can be set in light source carrier to many-one, to improve to LED illumination device inside sky Between utilization rate.
In some embodiments of others of the application, the light source carrier and circuit carrier can also be with split settings Realize electric connection under this layout between LED light source module and circuit, had between light source carrier and circuit carrier hard or Soft electric conductor, the soft electric conductor are, for example, conducting wire etc., and the electric conductor of the hard is, for example, contact pin etc..
As shown in Figure 1 C, in the present embodiment, the electric conductor 133 can be conducting wire, can enable by welding Its both ends is separately fixed at light source carrier 131 and circuit carrier 132, and the LED light source module and the electricity is electrically connected Road.
In the present embodiment, it is preferably arranged in a mutually vertical manner between the light source carrier 131 and circuit carrier 132, certainly, It is connected due to the two split settings and using soft electric conductor 133, the relative position of the two or posture can be become Change, certainly due to not be it is arranged in parallel, the circuit carrier 132 be a plate body in the case where, side is relatively narrow, no The electric connection is completed conducive to setting rigid conductive body 133.
As shown in figure iD, in the present embodiment, it is arranged in parallel between light source carrier 141 and circuit carrier 142, between the two may be used It is mutually located with the electric conductor 143 (such as contact pin) etc. by hard and realizes that the electrical property between LED light source module and circuit connects It connects.
The LED light source module includes: positive terminal and negative pole end, therefore visible, described in the embodiment of Fig. 1 C and 1D Electric conductor 133,143 has a pair for being separately connected the positive terminal and negative pole end, and the other end of a pair of conductive body 133,143 connects Two polar terminals of the circuit on the circuit carrier 132,142 are connected to, such as power output end is positive and cathode, power supply are defeated Outlet cathode can be grounded.
It should be noted that although not showing electric conductor in Figure 1A and 1B, in the embodiment of Figure 1A and 1B, the LED In the case that light source module includes: positive terminal and negative pole end, electric conductor equally has two-way, and one end of two-way electric conductor is separately connected The positive terminal and negative pole end of LED light source module, the other end of two-way electric conductor are connected to two of circuit on circuit carrier 102,112 A polar terminals, such as power supply output cathode end and power supply output negative pole end, power supply output negative pole end can be grounded.
In the embodiment of the application, the circuit carrier is plate body, shape include: rectangular, triangle, circle, The combined shaped of any one or more in trapezoidal, round and regular polygon, the side into 1C the combined shaped such as Figure 1A Shape and the trapezoidal shape etc. to connect.
In the embodiment of the application, in the light source carrier carry LED light source module loading end other than one or The structure of multiple outer surfaces can be changed according to the degree difference of radiating requirements.
As shown in Figure 2 A, in the present embodiment, in the case where radiating requirements are not very urgent, light source carrier 201 The back side 203 of loading end 202 can be a plane.
It as shown in Figure 2 B, in the present embodiment, is increasing heat radiation area, the back side of the loading end 212 of light source carrier 211 213 can be a cambered surface, the cambered surface of evagination preferably in diagram.
It as shown in Figure 2 C, is increasing heat radiation area, the back side 223 of the loading end 222 of light source carrier 221 in the present embodiment It can be and connect the convex-concave surface formed by multiple planes, such as the serrated surface that connects and composes of multiple teeth of diagram；Certainly exist In other embodiments, flat surface can be at the top of the tooth, to form the bigger convex-concave surface of heat dissipation area.
Similarly, the convex-concave surface is also possible to be connected by curved surface and be formed, or is connected and formed with curved surface by plane, ability Field technique personnel can should be realized that expansion is not repeated one by one herein according to the thought of the application.
Specifically, although in the embodiment of Fig. 2A to 2C, the back side of loading end 202,212,222 is shown only 203,213,223 shape, to meet different radiating requirements, still, in other examples, the light source carrier 201, 211,221 other surfaces, such as side, shape can also be changed, and be not limited with above-described embodiment and diagram.
It can be seen from the above, by light source carrier, the shape, structure of circuit carrier variation between permutation and combination can draw Variety carrier combination, for example, circuit carrier have 5 kinds of shapes (such as rectangular, triangle, circle, rectangular and trapezoidal combination, it is round and Regular polygon), light source carrier has 3 kinds of structures (back side of such as loading end is plane, cambered surface and serrated face), then can produce 5*3 =15 kinds of carrier combinations, are selected for the structure of different LED illumination devices, layout requirements, greatly strengthen layout Diversity, such as promote design convenience and efficiency.
In conclusion LED illumination device provided by the present application, comprising: light source carrier, for carrying LED light source module；Extremely A few circuit carrier, for carrying the circuit being electrically connected with the LED light source module；Wherein, the light source carrier and electricity Road-load body is ceramic material, has superelevation insulating coefficient and heating conduction；Carrier by ceramics as LED light source module, Realize the double effects for carrying its connection line and heat dissipation, also, also using ceramics substitution pcb board as bearer connection LED light Driving/functional circuit carrier of source module and also simultaneously realize to the heat dissipation of driving/functional circuit, so both improve lamps and lanterns General safety performance, and improve the integral heat sink performance of lamps and lanterns.
