The specific embodiment
In order to more fully understand technology contents of the present invention, below in conjunction with specific embodiment, technical scheme of the present invention is further introduced and explanation, but be not limited to this.
As shown in Figure 1 to Figure 3, the present invention has the LED lighting device of non-isolated power supply, comprise non-isolated power supply 11, and the LED lamp pearl 12 electrically connecting with non-isolated power supply 11, LED lamp pearl 12 is fixed on bakelite pcb board 13, and the one side of bakelite pcb board 13 is provided with for electrically connecting the printed circuit 131 of LED lamp pearl 12 and non-isolated power supply 11; The another side of bakelite pcb board 13 connects with the radiator being provided with 14 welded types, between bakelite pcb board 13 and radiator 14, is provided with solder(ing) paste layer 15.Radiator 14 is LED illumination housing, and it is also connected with fore shell 16 and lampshade 17.Wherein, non-isolated power supply 11 comprises current rectifying and wave filtering circuit 111 and reduction voltage circuit 112, and reduction voltage circuit 112 is inductance reduction voltage circuit or resistance reduction voltage circuit; The input of non-isolated power supply is alternating current.
Concrete structure also can be as shown in Figure 4 and Figure 5, and the end of LED illumination housing 14A is provided with the cavity for accommodating non-isolated power supply 11; The end of LED illumination housing 14A is also provided with lamp holder 19, and lamp holder 19 electrically connects with non-isolated power supply 11.Radiator 14 wherein and LED illumination housing 14A be equipped with when bakelite pcb board is directly soldered on radiator being convenient to the straight shape groove 141(heating of heating time to insert heating element heater, shorten the distance of heating element heater and solder(ing) paste layer 15), this straight shape groove 141 in use also can work to accelerate heat radiation simultaneously.
Owing to being soldered to the medial surface of radiator at bakelite pcb board, preferably adopt the laminating direct mode of heating in outside afterwards, the lateral surface of radiator is heated, consideration is heated evenly, and for reduce the heat time as far as possible, improve production capacity, be necessary the structure of straight shape groove further to optimize.
One of optimal way wherein, as shown in Figure 6 and Figure 7, increases the length straight connected in star 142 close with bakelite pcb board at straight shape groove 141, so that while heating, heating element heater more approaches bakelite pcb board, and don't can reduce the intensity of radiator.
Can also adopt two of optimal way, as shown in Figure 8 and Figure 9, at the kerve of straight shape groove 141, be provided with circular cavity 143, conveniently put into circular heating element heater.
Can also adopt three of optimal way, as shown in figure 10, straight shape groove 141 wherein adopts narrower structure, bakelite pcb board corresponding position, be provided with the circular cavity 144 that several communicate with straight shape groove 141, the diameter of this circular cavity 144 is greater than the width of straight shape groove 141, is conducive to insert larger heating head.This structure can adopt first extrusion molding to go out straight shape groove, then processes by smear metal, processes cylindrical cavity, also can adopt the mode of integral pressure casting.This structure is a kind of preferred embodiment, its role is to make radiator to there is good radiating effect, simultaneously, in the soldering process of bakelite pcb board, can adopt thicker circular heating head, and this heating head approaches the solder side of electric woods pcb board completely, can reduce the heat time, contribute to improve welding efficiency.Because the radiating groove on traditional radiator is narrow completely, is difficult to insert heating element heater (no matter be tabular, block, or pole shape), thereby affects heating effect.
