Abstract
The utility model discloses a light-emitting diode (LED) mining lamp with a fan, which comprises a reflecting cover, a printed circuit board (PCB) base, a radiating module, a top cover, a driving power supply, a PCB and an LED light source. The radiating module comprises a radiating body, a heat conducting pipe and the fan. When the mining lamp is lighted, heat produced by the LED light source is delivered to the PCB, the other end of the heat conducting pipe is heated so as to cause phase change of internal liquid, the heat is delivered to the radiating body fast, then the heat is taken away by using forced convection caused by the fan, heat resistance of an LED can be effectively reduced, and service life of the LED is prolonged.
Description
Technical field
The utility model relates to a kind of lighting, relates in particular to a kind of LED bulkhead lamp capable with fan.
Technical background
LED technology constantly full-fledged, cold white light LEDs has reached 120Lm/W, has been widely used in road lighting.The LED bulkhead lamp capable is also constantly released in recent years; Mostly the design of existing bulkhead lamp capable is that a reflection shield adds radiator, and power pack places the mode at radiator top, and led light source adopts integrated form encapsulation or COB packaged light source more; Because bulkhead lamp capable light emitting source area is little; Need be fansink designs very high, the heat that causes led light source to produce can't in time be led on the radiator, so the power of existing LED bulkhead lamp capable is mostly below 100W.Secondly, the existing easy dust stratification of LED bulkhead lamp capable, the long-time use influences outward appearance, poor heat radiation.
Be that March 3, publication number in 2010 are that invention that CN101660743A, name are called " the LED light fixture of radiator and band fan " is applied for a patent and disclosed a kind of LED light fixture that has fan on open; But this invention application is to all LED light fixtures; Be not the special LED bulkhead lamp capable that is directed against, its defective is: fan directly blows radiator, can produce bigger noise; Secondly fan is nearer from led light source, and fan reduces service life because of being heated.
Summary of the invention
Bad to existing LED bulkhead lamp capable heat radiation; Power is lower; The easy shortcoming of dust stratification dirt, we use for reference early stage computer CPU heat radiation and adopt metallic plate, more finally radiator; Up to the technological innovation and the computer to dissipate heat development course of the heat-pipe radiator combination fan that develops into main flow today, the utility model provides a kind of LED bulkhead lamp capable of fan combination heat pipe heat radiation.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
A kind of LED bulkhead lamp capable with fan comprises reflection shield, PCB base, heat radiation module, top cover, driving power, pcb board and led light source, and described heat radiation module comprises radiator, heat pipe and fan.
When lighting this bulkhead lamp capable, the heat that led light source produces is delivered to pcb board, and the other end of heat pipe is because of the internal liquid phase transformation of being heated; Be delivered to heat on the radiator fast; Utilize fan forced convection that heat is taken away again, can effectively reduce the LED thermal resistance, prolong the LED physical life.
Above-mentioned described a kind of LED bulkhead lamp capable with fan; Described PCB base is provided with groove; Described radiator is provided with porose; One end of said heat pipe is placed in the groove of said PCB base, and the other end of heat pipe passes the hole of radiator, and the quantity of said heat radiation body opening is identical with the quantity of heat pipe pipe.Simple in structure, easy for installation.
Above-mentioned described a kind of LED bulkhead lamp capable with fan, described radiator is provided with air inlet, and described top cover is provided with air outlet.
Be designed with air inlet on the radiator, be designed with air outlet on the top cover, formed the hot flow type passage that the turnover air channel is arranged, accelerate heat radiation, reduce the LED thermal resistance effectively.
Above-mentioned described a kind of LED bulkhead lamp capable with fan, it is characterized in that: described top cover is provided with button bit.The button bit that top cover is provided with is used for fixing described fan, makes that the installation of fan is more convenient.
