Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings and have
The utility model is described in further detail for body embodiment.
As shown in Figure 1, a kind of LED streetlamp power source module, including：
Housing 1, the housing 1 is specially the metal shell with U-shaped profile, including base and is symmetricly set on base two
The side of side, is provided with sliding slot 2 on the opposite face of two sides；
Circuit board 7, the underrun fastener of the circuit board 7 are fixedly connected with heat sink 9, and the two of the heat sink 9
Side is provided with fin 8, and the fin 8 is matched with the sliding slot 2, and the circuit board 7 is plugged in the sliding slot 2 by fin 8.
The circuit board 7 can be moved along sliding slot 2, and when it is time for repair, service personnel can be directly by the circuit board 7 together with scattered
Hot plate is pulled out from housing 1, and the circuit board 7 is pushed into sliding slot 2 together with heat sink after maintenance is good, avoids demounting bolt
The problem of causing to remove and install difficulty Deng fastener, meanwhile, carrying out installation positioning by the fin 8 of 9 both sides of heat sink can have
Effect avoids housing 1 from causing unnecessary abrasion to circuit board 7, and since housing 1 is metal shell, heat sink 9 dissipates for aluminium alloy
Hot plate or copper heat sink, are transferred heat on housing 1 by fin 8, can be effectively increased the heat dissipation area of heat sink 9,
Strengthen heat dissipation effect.
The card slot 3 for fixed cable is provided with the housing 1, the card slot 3 is arranged on the side on the base, by
Need to be connected with the electric elements such as power supply in circuit board 7, the cable of connecting circuit element extends to the outer of housing 1 by card slot 3
Portion, avoids cable from causing to interfere to installation relation, while card slot 3 can be connected up with personnel convenient to overhaul, avoid cable clutter from placing.
Some terminals 4 are provided with the circuit board 7, the terminal 4 is used to install LED core sheet 6, the LED chip
The LED light-emitting component 5 of stationary arrangement is evenly distributed with plate 6, specifically, terminal 4 and the mounting terminal of 6 bottom surface of LED core sheet
