Abstract
The utility model discloses an LED ceiling lamp and relates to the field of semiconductor lighting technology. The LED ceiling lamp comprises a transparent lampshade, a power supply module and LED elements, and is characterized in that: the anode and cathode pins of all LED elements are arranged on two sides of a double-sided copper foil circuit board through paste welding; circuit board elements are vertically and parallelly arranged in the lampshade; according to the design, the surface area of radiation copper foil is doubled compared with that of the prior scheme; the side of the lampshade is provided with air slots and the bottom surface of the lampshade is provided with air vents, so the conditions of the exchange of the air inside and outside the lamp are further improved and the radiation performance of the lamp is greatly improved; and thus, the temperature of the LED chip can be effectively controlled so as not to rise overhigh and the long service life of the LED lamp can be guaranteed. The LED ceiling lamp can create certain social and economic benefits.
Description
Technical field
The utility model relates to lighting device, is specifically related to technical field of semiconductor illumination.
Background technology
Existing a large amount of lamp affixed to the ceiling that uses is a fluorescent lamp, development along with the semiconductor LED lighting engineering, the LED lamp affixed to the ceiling that the low-power LED of the direct insertion encapsulation of a kind of usefulness two pin is assembled into has also come out for many years, it is to be welded on the circuit board by nearly the LED more than hundred is slotting, again with this circuit board horizontal in a Transparent lamp shade, and be equipped with power module and constitute existing LED lamp affixed to the ceiling.One of technological difficulties of LED illumination are radiating treatment, because the working life of LED is decided by the operating temperature of LED, has only and reduce the operating temperature value as much as possible and could prolong its life-span to greatest extent.The structures shape of existing LED lamp affixed to the ceiling its radiating treatment bad, reason be rely the heat radiation circuit board Copper Foil area less, the air-flow give-and-take conditions of light fixture are poor, the heat that makes LED produce can not in time derive and dissipate, gathering of heat makes the junction temperature of led chip raise fast, long-term work causes the chip light decay to quicken under hot conditions, and working life shortens.
Goal of the invention
The purpose of this utility model is to make improvements by the structure to the LED lamp affixed to the ceiling, improves the heat dispersion of light fixture, reaches the purpose that improves the light fixture useful working life and then improve its economic results in society
Summary of the invention
The technical solution of the utility model is: circuit board adopts some two-sided copper foil plates, all the both positive and negative polarity pin of LED elements pastes respectively on the Copper Foil that is welded in the circuit board two sides and need not to bore pin holes, the both positive and negative polarity pin can stay longly so that increase heat-conducting area as far as possible, having welded each bar circuit board assemblies vertical parallel in lampshade of LED element arranges, make the unified bottom surface of pointing to lampshade of light direction of LED, there is lead to connect between each bar circuit board, is connected with power module again and promptly constitutes LED lamp affixed to the ceiling of the present utility model.In order further to improve light fixture inner air and outer air give-and-take conditions, in the side of transparent lamp shade some air channels are set, the passage of some quantity is set in the bottom surface.
Technique effect
After adopting the technical solution of the utility model, Copper Foil area on the circuit board increases exponentially than existing scheme, this promptly is to have increased cooling surface area exponentially, the both positive and negative polarity pin stays to such an extent that the long heat that helps the chip generation is transmitted on the Copper Foil fast, the vertical parallel of each circuit board arrange and lampshade on the ventilation hole slot technical measures are set etc., all improve the heat dispersion of light fixture effectively, helped prolonging the useful working life of light fixture.
Description of drawings
Fig. 1 is the AA view profile of the LED lamp affixed to the ceiling of embodiment scheme;
Fig. 2 is the vertical view of LED lamp affixed to the ceiling.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model LED lamp affixed to the ceiling is made up of transparent lamp shade 1, power module 6, some two-sided copper foil circuit boards 2 and several LED elements 3 of welding on it, it is characterized in that: the both positive and negative polarity pin of each LED element pastes respectively on the two sides Copper Foil that is welded in double-sided circuit, each bar circuit board assemblies vertical parallel in lampshade is arranged, there is lead to connect between each bar circuit board, is electrically connected with power module again.The cubic side of transparent lamp shade 1 has some air channels 4, and sole arrangement has the passage 5. of some quantity
