Abstract
The utility model discloses a long-life LED (Light Emitting Diode) street lamp switch power supply. The long-life LED street lamp switch power supply comprises a PCB (Printed Circuit Board), electronic components, graphite bodies and a cavity body radiator, and is characterized in that the electronic components are welded on the PCB at first, the graphite bodies are formed according to the distribution of the electronic components on the PCB, and are embedded on the electronic components on the PCB of the LED street lamp switch power supply, then the PCB and the graphite bodies are pushed into the cavity body radiator, the graphite bodies and the cavity body radiator are fixed and tightly adhered, and two ends of the cavity body radiator are sealed by block covers at last. Since the graphite bodies have good heat conducting performances, the temperature of the electronic elements in the power supply can be limited to be a relatively low value, thus the service life of the LED street lamp switch power supply can be greatly prolonged, and the whole service life of an LED street lamp is further prolonged; and simultaneously, since a glue encapsulation processing is not needed to be carried out, not only can invisible damage and tightening strain of the electronic components, caused during a high-temperature baking process, be effectively avoided, but also the cost is effectively reduced.
Description
Technical field
The utility model belongs to the lamp power field, relates to a kind of long-life LED road lamp switch power supply.
Background technology
At present, the numerous cities of China install that the LED street lamps are very usual, and the LED street lamp be a light source with large-power light-emitting diodes (LED), is a kind of solid-state cold light source, compares with the conventional high-tension sodium vapor lamp, characteristics such as have environment friendly and pollution-free, little power consumption, light efficiency is high, the life-span is grown.But, people at propaganda LED street lamp high light efficiency, long-life while is but ignored or avoided another key issue: i.e. life-span of LED streetlamp driving power supply.The LED road lamp power supply need adopt the filling heat-conducting glue to come heat conduction to inner components and parts heat radiation usually.But the heat-conducting glue heat conductivility is relatively poor, and needs high-temperature baking, tends to cause components and parts stealth damage in various degree to pull with tight bundle, stays hidden danger possibly.At present quality preferably the life-span of LED road lamp switch power supply approximately only have 3 years, become the bottleneck of restriction LED street lamp bulk life time.The operate as normal life-span of LED road lamp switch power supply is depended on the life-span of the employed electronic devices and components of LED road lamp switch power supply; The life-span of electronic devices and components depend on again electronic devices and components when work self temperature---10 ℃ of the every declines of working temperature, the electronic devices and components life-span approximately doubles.Therefore, reduce LED road lamp switch power supply internal temperature, for the life-span of improving LED road lamp switch power supply, and then the life-span of raising LED street lamp is significant, and this also is the problem of present LED road lamp switch solution that power supply is needed badly.
The utility model content
The purpose of the utility model is to provide a kind of functional reliability high, and simple in structure, lower-cost LED road lamp switch power supply can effectively improve LED road lamp switch power source life, and then improves LED street lamp bulk life time.
The technical scheme of the utility model is: a kind of long-life LED road lamp switch power supply comprises: printed circuit board (PCB), electronic devices and components, graphite body and cavity heat radiator; Earlier electronic devices and components are welded on the printed circuit board (PCB); According to electronic devices and components arranging on printed circuit board (PCB) with graphite body machine-shaping; And be nested on the electronic devices and components on the LED Switching Power Supply printed circuit board (PCB); Push printed circuit board (PCB) and graphite body in the cavity heat radiator then, graphite body and cavity heat radiator are fixed, are adjacent to, at last the cavity heat radiator two ends are sealed with blanking cover.
The utility model adopts the good effect that produces after the technique scheme to be: because graphite body has good heat-conducting; Can effectively the temperature of power supply internal electronic component be clamped down on a low relatively value; Thereby improve LED road lamp switch power source life greatly, and then improve LED street lamp bulk life time.Owing to need not do the encapsulating processing, the stealth that in the time of both can avoiding high-temperature baking effectively components and parts is caused damage and tight bundle are pulled, and have reduced cost again effectively simultaneously.
Description of drawings
Fig. 1 is the structural representation of a kind of long-life LED of the utility model road lamp switch power supply.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.As shown in Figure 1, a kind of long-life LED road lamp switch power supply mainly comprises: printed circuit board (PCB) 1, electronic devices and components 2, graphite body 3 and cavity heat radiator 4.Earlier electronic devices and components 2 are welded on the printed circuit board (PCB) 1; According to electronic devices and components 2 arranging on printed circuit board (PCB) 1 with graphite body 3 machine-shapings; The graphite body 3 of machine-shaping is nested on the electronic devices and components 2 on the LED Switching Power Supply printed circuit board (PCB) 1; Push printed circuit board (PCB) 1 and graphite body 3 in the cavity heat radiator 4 then, graphite body 3 and cavity heat radiator 4 are fixed, are adjacent to, at last cavity heat radiator 4 two ends are sealed with blanking cover.
The principle of the utility model is: the good heat conductive performance of utilizing graphite body 3 self to be had; The heat that produces during with Switching Power Supply electronics components and parts 2 work is transmitted on the cavity heat radiator 4 through graphite body 3 quickly and evenly, again by cavity heat radiator 4 through being delivered in the air with the cross-ventilation mode.
Because graphite body has good heat-conducting, can effectively the power supply internal temperature be clamped down on a low relatively value, thereby improve greatly the LED Switching Power Supply life-span, and then improve LED street lamp bulk life time.Owing to need not do the encapsulating processing, the stealth that in the time of both can effectively avoiding high-temperature baking components and parts is caused damage and tight bundle are pulled, and have reduced cost again effectively simultaneously.
