Abstract

The utility model discloses an LED radiator, which is made by machining aluminium or A-alloy materials with strong heat conduction capability, and the size of the LED radiator can be determined as required. The radiator is conical and hollow, while the front end is big and the rear end is small. The radiator is characterized by comprising an outer casing layer and an inner casing layer; a heat insulation cavity is formed between the outer casing layer and the inner casing layer; a groove allowing a transparent cover to be placed is formed at the front end of the radiator, and a round aluminium substrate for installing an LED is also arranged at the front end of the radiator; threaded holes are formed on the round aluminium substrate; and a plurality of threads are formed at the rear end of the radiator. In conclusion, compared with a die-cast radiator, the radiator provided by the utility model has fewer impurities and high heat conduction coefficient and can well solve the radiating problem of an LED lamp. The radiator has the advantages of simple and tasteful appearance, low probability of dust accumulation, simpleness in cleanup and the like.

Description

A kind of LED radiator

Technical field

The utility model relates to the LED lighting field, particularly relates to a kind of LED radiator.

Background technology

Light-emitting diode (LED) has advantages such as low power consuming, power saving, life-span be long, durable, thereby is expected source, the traditional Mingguang City of replacement is become following lighting source.LED possesses following advantage as lamp light source: consumed power is little, and working temperature is low, adopts low-voltage power supply, do not need one-tenth the design, reliability height, the annex of High-Voltage Insulation few, simple in structure, save raw material, not inflation, not sealing, do not want the heavy sheet glass shell, the energy impact resisting vibrating; The LED response time is short, basic inertialess, and controllability is good; The LED volume is small and exquisite in addition, can make small-sized and miniature light fixture, is particularly suitable for special occasions and uses.

Along with power increases, current potential must increase, thereby the used heat that electric heating that LED produces flows can't effectively shed, and causes the LED life-span seriously to descend.The LED luminous efficiency can reduce along with service time and number of times, and too high contact-making surface temperature then can be quickened the decay of LED luminous efficiency, so dispel the heat into the LED weakness.

Increasingly mature with the work chip technology, single led chip input power can reach 5W, even higher, also more and more seems important so prevent that the LED working temperature is too high.If can not effectively chip heat be shed, it is more and more obvious that following one by one thermal effect also can become, and makes chip contact-making surface temperature raise, and then directly reduce the photon energy that chip penetrates, and reduces light extraction efficiency.The spectrum that the rising of temperature also can make chip launch produces red shift, and the colour temperature quality descends.

LED radiator commonly used at present is an aluminium die casting radiator, and its appearance has radiating fin, can reach the purpose of heat radiation to a certain extent, but its conductive coefficient is low, and overstocks dust easily on the fin, is difficult to cleaning.

Summary of the invention

At the problems referred to above, the purpose of this utility model is to provide a kind of LED radiator, reaches the purpose of saving cost, efficiently radiates heat.

For achieving the above object, the technical scheme that the utility model proposed is: a kind of LED radiator, be the little cone shape of internal cavities and the big rear end of front end, it is characterized in that, described radiator contains one deck outer shell and hypostracum, has a heat-insulation chamber between outer shell and hypostracum, contain on the described radiator front end and be useful on the groove of placing diffuser, and front end has one the circular aluminium base of LED is installed, contain screwed hole on the described circular aluminium base, its feature is that also described radiator rear end contains screw thread.

The screwed hole number that contains on the described circular aluminium base is for being at least one.

Described LED radiator adopts the good aluminum or aluminum alloy material mechanical of heat conductivility to process, and its size and size can be determined as required.

In sum, radiator described in the utility model is compared with aluminium die casting radiator, impurity still less, the conductive coefficient height can solve LED lamp heat dissipation problem, and it is simply generous to have profile, is not easy to overstock dust, clears up advantages such as simple.

Description of drawings

Fig. 1 is a LED radiator integral structure chart described in the utility model;

Fig. 2 is a LED radiator cutaway view described in the utility model;

Fig. 3 is the circular aluminium base structure chart of the LED radiator shown in the utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

As Fig. 1 is as described in the LED radiator integral structure chart described in the utility model, a kind of LED radiator 1, and its overall structure is the little cone shape of an internal cavities and the big rear end of front end; And for example shown in Fig. 2 LED radiator described in the utility model cutaway view, radiator 1 contains one deck outer shell 101 and hypostracum 102,102 of outer shell 101 and hypostracums have a heat-insulation chamber 103, contain on radiator 1 front end and be useful on the groove 107 of placing diffuser, and front end has one and LED is installed with circular aluminium base 106,106 contain screwed hole 105 on the circular aluminium base, screw thread 108 is contained in radiator 1 rear end in addition, as Fig. 3 is shown in the circular aluminium base structure chart of the LED radiator shown in the utility model, install LED with screwed hole 105 numbers on the circular aluminium base 106 at least greater than one.

The ED radiator adopts the good aluminum or aluminum alloy material mechanical of heat conductivility to process, and its size and size can be determined as required.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; in the form and details the utility model is made various variations, be protection range of the present utility model.
