Background technique

Semiconductor light-emitting diode lamp tool is LED (Light Emitting Diode) lamps and lanterns, is a kind of semiconducting solid Luminescent device.LED is as a kind of novel green light source product, and necessarily the trend of future development, 21st century will enter Using LED as the novel illumination light source epoch of representative.LED is referred to as forth generation lighting source or green light source, has energy conservation, ring The features such as guarantor, service life long, small in size, it can be widely applied to various instructions, display, decoration, backlight, general lighting and city The fields such as night scene.

But so its calorific value of energy-efficient lamps and lanterns is really very big, therefore LED lamps cooling is also very important, The equally lamps and lanterns of power factor and the lamp bead with quality, if radiating condition is bad, lamp bead works at high temperature, and light decay can be very Greatly, lamp life can be reduced.And the reason of LED bulb fever is not to be completely converted into luminous energy because of the electric energy being added, But a part transforms into thermal energy, electro-optical efficiency 20~30% or so.That is about 70% electric energy all becomes Thermal energy.Because LED light source itself does not have infrared ray, ultraviolet light, LED light source itself does not have heat loss through radiation function, and LED shines The sinking path of bright lamp tool can only export heat by the radiator combined closely with LED lamp bead plate.

But present heat dissipation technology is all that heat sink is directly contacted with lamp bead or lamp plate to distribute heat mostly, due to dissipating The good conduction of heat of hot plate, heat are likely to send back LED lamp bead or lamp plate again, influence to radiate.

Utility model content

The purpose of this utility model is to provide the LED illumination lamps for being conducive to heat dissipation, it is guaranteeing the same of LED lamps cooling When avoid heat disturbance to LED light.

The utility model to achieve the above object, is achieved through the following technical solutions:

Conducive to the LED illumination lamp of heat dissipation, including LED lamp panel, the light-emitting surface of the LED lamp panel is equipped with reflector, described Transparent cover is equipped at the rim of a cup of reflector, the back side of the LED lamp panel is equipped with cooling piece, and the back side of the cooling piece is equipped with sky Heart thermal column, the outer surface of the hollow thermal column are along the circumferential direction equipped with multiple first heat sinks, outside first heat sink It is cased with first shell, is cased with second shell outside the reflector, the first shell is fixedly connected with second shell, and described first Shell and second shell are equipped with multiple air holes, and the cooling piece and LED lamp panel connect to power supply respectively.

Further, the outer wall of the reflector is equipped with multiple second heat sinks, first heat sink and the second heat dissipation Plate is integrally formed.

Further, the outer wall of the reflector and the outer surface of transparent cover are coated with heat loss through radiation coating.

The prior art is compared, the utility model has the beneficial effects that:

Increase a cooling piece between LED lamp panel and radiator, makes heat can only be from LED lamp panel to radiator list To transmitting, heat is prevented to be back to LED lamp panel by radiator, and open up multiple air holes on shell, shell can be made intracorporal Air and outside air form convection current, and radiator is transmitted to the intracorporal heat of shell and is exchanged in outside air, imitate heat dissipation Fruit is more preferable, and the area of heat sink is far longer than the area of LED lamp panel, so that the area of heat exchange increases, increases radiating efficiency, prolongs The service life of long LED lamp bead.

Specific embodiment

The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen It please limited range.

Described in the utility model is conducive to the LED illumination lamp of heat dissipation, and main structure includes LED lamp panel 1, and LED lamp panel 1 can Think circle or rectangular, the light-emitting surface of the LED lamp panel 1 is equipped with reflector 2, and the shape of reflector 2 is mutually fitted with LED lamp panel It answers, since the light that LED lamp bead issues is diverging light, so reflector 2 is needed to carry out optically focused, is equipped at the rim of a cup of the reflector 2 Transparent cover 3, light source is brighter, luminous efficiency is higher in order to make, and transparent cover 3 can be convex lens, the back of the LED lamp panel 1 Face is equipped with cooling piece 4, and the heat that LED lamp panel 1 distributes is passed uni-directionally to the external world by cooling piece 4, and prevents extraneous heat from returning It is transmitted to LED lamp panel 1, the back side of the cooling piece 4 is equipped with hollow thermal column 5, it is possible to reduce weight, and in hollow thermal column 5 The heat dissipation area at boring is increased for the more solid thermal column in portion, keeps heat dissipation effect more preferable, the hollow thermal column 5 Outer surface is along the circumferential direction equipped with multiple first heat sinks 6, increases the heat exchange area with air, improves heat exchange efficiency, and described the It is cased with first shell 7 outside one heat sink 6, second shell 8, the first shell 7 and second shell 8 are cased with outside the reflector 2 It can be screwed connection, can also be threadedly coupled, the first shell 7 is equipped with multiple air holes 9 with second shell 8, Make shell is inside and outside to generate convected air, facilitates the intracorporal hot-air of shell to exchange to outside shell, keep heat dissipation effect more preferable, the refrigeration Piece 4 and LED lamp panel 1 connect to power supply respectively, and power supply line can be drawn out of hollow thermal column 5, or draw from side.
