The structure of the LED module comprises a base plate, and the primary technical points of the invention are that an aperture is arranged on the base plate and an LED light is put in the aperture; a thermal pad is arranged at the bottom of the LED light, and the anode and cathode of the LED light are respectively connected with welding spots on the base plate through a bus-bar, and the welding spots are respectively connected with the anode and cathode of a power supply. The thermal pad directly contacts a radiating body, and then the generated heat is transmitted to the radiating body, therefore, the better radiating effect is ensured.
Description
Technical field
The present invention relates to a kind of lighting apparatus, relate in particular to a kind of lighting apparatus of high-powered LED lamp.
Background technology
The LED light emitting module is by a slice circuit board, and at least one LED lamp is divided into circuit board combination and forms, and in the high-power LED lamp light emitting module, good, bad the becoming of heat radiation influences one of good, bad principal element of its performance.
At present, in order to realize the heat radiation of high-powered LED lamp, method is not quite similar, and is welded on aluminum base PCB as a kind of method for the LED lamp, promptly on the aluminium printed substrate, LED heat conductive pad and aluminium base are welded or use the heat-conducting silicone grease combination, the aluminium base bottom surface makes its purpose that reaches heat radiation more directly or with heat-conducting silicone grease and radiator combination, but because aluminum base PCB is much higher than common PCB price, the cost height should not be promoted.
Summary of the invention
The present invention is directed to deficiencies such as cost height, difficult processing, weak heat-dissipating in the prior art, provide a kind of cost low, simple in structure, the LED light emitting module that has radiator structure of good heat dissipation effect.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of LED light emitting module that has radiator structure, comprise base plate, its main points are that described base plate is provided with the hole, described LED lamp stretches into its hole, the bottom of described LED lamp is provided with heat conductive pad, and the both positive and negative polarity of described LED lamp is connected with phase of solder joint on the base plate by bus respectively, described solder joint links to each other with the both positive and negative polarity of power supply respectively, heat conductive pad directly contacts with radiator, and the heat of generation is directly conducted to radiator, has better heat radiating effect.
In the technique scheme, the heat conductive pad baseplane and the base plate baseplane of the setting of described LED lamp are in same horizontal plane, and heat conductive pad directly contacts with radiator, reduce medium, thereby reduce LED radiator structure thermal resistance, make the great power LED cooling better effects if, it is faster to dispel the heat.
In the technique scheme, the heat conductive pad baseplane that described LED lamp is provided with is below the base plate baseplane, and heat conductive pad directly contacts with radiator, reduces medium, thereby reduces LED radiator structure thermal resistance, makes the great power LED cooling better effects if, and it is faster to dispel the heat.
In the technique scheme, the aperture in described hole makes things convenient for LED location and installation greater than the external diameter of LED lamp.
Beneficial effect: the present invention compared with prior art has following beneficial effect:
1) the present invention adopts the hole of hollow out to install and is welded with high-powered LED lamp, and LED lamp side does not have other medium, makes the heat of its generation be directly conducted to radiator, has better heat radiating effect.
2) heat conductive pad directly contacts with radiator, reduces medium, thereby reduces LED radiator structure thermal resistance, makes the great power LED cooling better effects if, and it is faster to dispel the heat.
3) the present invention adopts common pcb board, replaces traditional aluminium pcb board, and because the well good radiator structure of tool of the present invention, so the common pcb board of employing can reach the heat radiation requirement, and common pcb board is than aluminium pcb board low price, and its cost is low;
4) can arrange the installing hole of LED according to different purposes, make the variation of light emitting module shape, circle, bar shaped, a series of shapes such as rectangle or font, it has advantages such as attractive in appearance, generous.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
See Fig. 1, Fig. 2, Fig. 3, because the utility model relates to the innovation of radiator structure, so when drawing, base plate 1 also is that the circuit connection on the pcb board is not drawn.
Described base plate 1 adopts common pcb board, cost is lower, described base plate 1 has hole 5, and the quantity in hole 5 is provided with according to the size of brightness, and in general, the size of brightness is controlled by the quantity of LED lamp 3, that is to say, the quantity in hole 5 is provided with according to the quantity of LED lamp 3 is corresponding, also can be according to different purposes, and aligned apertures 5, make the variation of light emitting module shape, can be series of shapes such as circle, bar shaped, rectangle or font, as preferably, described hole 5 is a circular hole, and the aperture is bigger than LED3 lamp external diameter, makes things convenient for LED location and installation.
The both positive and negative polarity of described LED lamp 3 is connected with phase of solder joint on the base plate 1 by bus 2 respectively, and described solder joint links to each other with the both positive and negative polarity of power supply respectively.
The bottom of described LED lamp 3 is provided with heat conductive pad 4, described heat conductive pad 4 bottom surfaces can scribble heat-conducting silicone grease, as preferably, heat conductive pad bottom surface 4 that described LED lamp 3 bottoms are provided with and base plate 1 bottom surface are in same horizontal plane or slightly outstanding, make the direct and radiator combination of LED lamp 3 energy, owing to have only a contact-making surface between LED lamp 3 and the radiator, there is not medium, the minimum that thermal resistance reduces, as scribbling heat-conducting silicone grease between heat conductive pad 4 and the radiator contact-making surface, further increase heat-conducting effect, the heat of LED lamp 3 can effectively be distributed.
