Abstract
A radiator structure for an LED spot lamp comprises a metal lamp cup and a plastic lamp holder, wherein an accommodating cavity is formed inside the metal lamp cup; a fixing through-hole provided with internal threads is formed at the upper part of the metal lamp cup; the plastic lamp holder is screwed in the fixing through-hole; and heat dissipation fins are formed on the external surface of the metal lamp cup. The radiator structure has the benefits as follows: the radiator structure is characterized by simple structure, small volume and good radiating effect by adopting the structure, so that the service life of the LED spot lamp can be prolonged.
Description
(1) technical field
The utility model relates to a kind of LED shot-light, relates in particular to a kind of radiator structure of LED shot-light.
(2) background technology
Because small-power type LED shot-light has environmentally safe, energy savings, distinct advantages such as low price just progressively substitute present incandescent lamp.Existing LED shot-light mainly comprises metalized lamp cup and plastic lamp base, form container cavity in the metalized lamp cup, LED emitting components and circuit board are installed in the container cavity, the lower end of plastic lamp base is fixed on the upper end of metalized lamp cup, the upper end of plastic lamp base extends upward the formation fixed part, and this fixed part is provided with the pin that is connected with the LED emitting components.Because the LED emitting components is in using luminescence process, can send a large amount of heat energy simultaneously, these heat energy are not if get rid of for a long time, can influence the life-span of LED emitting components, solve heat dissipation problem if increase the length of metalized lamp cup, will certainly increase the whole height of LED shot-light, make troubles to installation, radiating effect neither be fine simultaneously.
(3) summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provide a kind of simple in structure, volume is little, good heat dissipation effect, make the radiator structure of LED shot-light of the long service life of LED shot-light.
The technical scheme in the invention for solving the technical problem is: a kind of radiator structure of LED shot-light, comprise metalized lamp cup and plastic lamp base, form container cavity in the described metalized lamp cup, the top of described metalized lamp cup is provided with the fixed via with internal thread, described plastic lamp base spiral shell is located in this fixed via, is formed with radiating fin on the outer surface of described metalized lamp cup.
Further, described plastic lamp base is provided with at least two passages that are connected with described container cavity.
The utility model in use, plastic lamp base is bolted in the top of metalized lamp cup, LED emitting components and circuit board are installed in the container cavity of metalized lamp cup, the pin that is connected with the LED emitting components is installed on the plastic lamp base, pin and power connection are got final product.The heat energy that the LED emitting components produces outwards dispels the heat by metalized lamp cup, and this metalized lamp cup adopts the aluminum alloy materials of good heat conductivity, and design has many radiating fins on its outer surface, has increased area of dissipation, makes good heat dissipation effect.Simultaneously, the height of plastic lamp base reduces relatively, and increases the height of metalized lamp cup, makes the height of whole LED shot-light not increase, but area of dissipation increases, and makes the good heat dissipation effect of LED shot-light to have prolonged service life, also is convenient to install.Because plastic lamp base is provided with at least two passages that are connected with container cavity, air outside can exchange by the air in the container cavity of passage and metalized lamp cup, thereby the heat in the container cavity of metalized lamp cup is taken away, reach better heat radiating effect, prolong the service life of LED shot-light.
The beneficial effects of the utility model are: adopt said structure, make the utlity model has simple in structure, volume is little, the characteristics of good heat dissipation effect, makes obtain prolonging the service life of LED shot-light.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of radiator structure of LED shot-light, comprise metalized lamp cup 1 and plastic lamp base 2, form container cavity 3 in the described metalized lamp cup 1, the top of described metalized lamp cup 1 is provided with the fixed via 4 with internal thread, described plastic lamp base 2 spiral shells are located in this fixed via 4, are formed with radiating fin 5 on the outer surface of described metalized lamp cup 1, and described plastic lamp base 2 is provided with at least two passages 6 that are connected with described container cavity 3.
The utility model in use, plastic lamp base 2 is bolted in the top of metalized lamp cup 1, in the container cavity 3 of metalized lamp cup 1 LED emitting components and circuit board are installed, the pin that is connected with the LED emitting components is installed on the plastic lamp base 2, pin and power connection are got final product.The heat energy that the LED emitting components produces outwards dispel the heat by metalized lamp cup 1, and this metalized lamp cup 1 adopts the aluminum alloy materials of good heat conductivity, and designing on its outer surface has many radiating fins 5, has increased area of dissipation, makes good heat dissipation effect.Simultaneously, the height of plastic lamp base 2 reduces relatively, and increases the height of metalized lamp cup 1, makes the height of whole LED shot-light not increase, but area of dissipation increases, and makes the good heat dissipation effect of LED shot-light to have prolonged service life, also is convenient to install.Because plastic lamp base 2 is provided with at least two passages 6 that are connected with container cavity 3, air outside can exchange by the air in the container cavity 3 of passage 6 and metalized lamp cup 1, thereby the heat in the container cavity 3 of metalized lamp cup 1 is taken away, reach better heat radiating effect, prolong the service life of LED shot-light.
Claims (2)
1. the radiator structure of a LED shot-light, comprise metalized lamp cup and plastic lamp base, form container cavity in the described metalized lamp cup, it is characterized in that: the top of described metalized lamp cup is provided with the fixed via with internal thread, described plastic lamp base spiral shell is located in this fixed via, is formed with radiating fin on the outer surface of described metalized lamp cup.
