Abstract
A heat dissipation device for LED pins of an LED lamp belongs to LED luminaire. An LED cluster (6) is mounted on an LED cluster mounting board (7), and the pins thereof form an LED pin array (10); then the LED cluster mounted on the LED cluster mounting board (7) is clamped on a transparent lower housing (11) with more than two gas circulation and heat dissipation lower inlets (8); finally, a safety wall (9) is sheathed on the transparent lower housing (11) to form a component. The component is then clamped on a lower opening of an upper housing (5); two or more gas circulation and heat dissipation upper outlets (3) are formed on the upper portion of the upper housing (5); the input terminal I (1) and the input terminal II (2) of an AC source are mounted on the upper outer section of the upper housing (5); and an AC/DC power converter (4) and an LED power line (12) are mounted on the upper inner section of the upper housing (5). The heat dissipation device can ensure that the LED works at lower junction temperature so as to effectively delay luminous decay and prolong the service life, thereby fully improving the illumination effect of the LED. The heat dissipation device suits LED luminaire.
Description
Technical field: the utility model relates to the LED lighting, and particularly a kind of LED lamp LED continues to employ heat abstractor from pin.
Background technology: LED illumination is the mainstream development direction of current world illumination revolution.Yet use in the illumination at numerous LED, but run into and how to solve numerous LED collection and adorn a heat radiation difficult problem compressed together.Though what have has solved this problem substantially, it is many to consume heat sink material, and complex structure and cost are higher, and this all hinders or has delayed the LED energy-saving illumination uses fast and popularize.
Summary of the invention: the purpose of this utility model is to provide a kind of LED lamp LED to continue to employ heat abstractor from pin, utilizes LED to continue to employ the double as radiator and place the circulated gases environment and be reached for the purpose of LED lamp heat radiation from pin.
Formation of the present utility model: AC power AC two inputs, circulation heat radiation gas upper outlet on last shell and the shell, the lower case and the gas inlet that dispels the heat down, pin cluster array and LED cluster installing plate are drawn in LED cluster and himself, safe enclosure wall and power supply AC/DC converter and LED supply lines are formed, LED cluster 6 is installed on LED cluster installing plate 7 and stays it to draw pin and constitutes LED self pin array 10, overlap the safe enclosure wall 9 of card again in printing opacity lower casing 11 after being installed in printing opacity lower casing 11 again with circulation heat radiation gas lower inlet 8 more than 2, constituent components, again this assembly is installed in the end opening of shell 5, the top of last shell 5 is provided with circulation heat radiation gas upper outlet 3 more than 2, AC power AC input I 1, power supply AC input II 2 is installed on the outer top of shell 5, and power supply AC/DC converter 4 and DC output line thereof are that LED supply lines 12 is installed on shell 5 internal upper parts.
Compared with the prior art, the utility model can be with succinct effectively structure, no secondary heat radiation energy consumption, lower cost and the heat that produces when being beneficial to suitability for industrialized production LED is worked directly place the circulated gases environment by the LED terminal pin of self, gas by circulation is taken out of effectively to the lamp external space, and LED is worked under the lower junction temperature condition, delays light decay effectively, life-saving is given full play to the function illuminating effect of energy-conservation LED.
Description of drawings: accompanying drawing is the utility model structural representation.
1. power supply AC input I among the figure, 2. power supply AC input II, 3. circulation heat radiation gas upper outlet, 4. power supply AC/DC converter, 5. go up shell, 6.LED cluster, 7.LED cluster installing plate, 8. circulation heat radiation gas lower inlet, 9. safe enclosure wall, 10.LED self pin array, 11. printing opacity lower casings, 12.LED supply lines.
The specific embodiment: as shown in the figure, LED cluster 6 is installed on LED cluster installing plate 7, and stay and draw pin double as radiator under it, constitute LED self pin array 10, refill in the bottom has the printing opacity lower casing 11 of circulation heat radiation gas lower inlet 8, and press-fit safe enclosure wall 9, constituent components, again this assembly firmly is installed in the end opening of shell 5, the top of last shell 5 is provided with circulation heat radiation gas upper outlet 3 more than 2, AC power AC input I 1, power supply AC input II 2 is installed on the outer top of shell 5, and power supply AC/DC converter 4 and DC output line thereof are that LED supply lines 12 is installed on shell 5 internal upper parts, is 6 power supplies of LED cluster by the DC line.
