Description
One, technical field:
The utility model relates to the LED unit of solar energy lamp use and the LED wick of composition thereof.
Two, background technology:
Though compare with traditional bulb, light emitting diode has that volume is light and handy, the life-span is long and can save plurality of advantages such as the energy in a large number, and its brightness ratio conventional lamp is inferior.Therefore, generally in use, can use a plurality of light emitting diodes to be connected on the circuit board usually, especially low power light emitting diode is to increase its luminosity.Light emitting diode is by the circuit board heat radiation, but because the present employed circuit board of solar energy lamp is mainly made with epoxy resin and glass fibre, its radiating effect is poor.Along with increasing of light emitting diode quantity, its heat easily gathers and distributes and do not go out, and diode is with the rising of temperature, and its electric current continues to increase, the increasing of electric current, its temperature is raise, produce vicious circle, the light decay of light emitting diode is serious, finally can not use, so the service life of actual leds is shorter.Moreover electronic building bricks such as many electric capacity, resistance that can release heat are arranged simultaneously also on the circuit board, make heat localization more of this circuit board, heat is not easy fast that conduction is distributed to the external world, and it does not meet the needs of LED heat radiating, cause its Light-Emitting Diode light decay speed fast, service life is short.In order to solve heat dissipation problem, my unit had once installed the heat abstractor that thermal grease sheet and metal fin are formed additional in the circuit board back, and its radiating effect has been promoted much, has also prolonged the service life of light emitting diode.But it is indirectly heat radiation, mounting process complexity not only, and connection reliability is poor, heaviness, and radiating effect does not reach optimal effect yet.
Three, summary of the invention:
The utility model is exactly to solve now with the problems referred to above that exist in the technology, provides that a kind of radiating effect is better, light decay slow, the LED unit of the direct heat radiation of light emitting diode longer service life and the wick of composition thereof.
For addressing the above problem, technical solution of the present utility model is: a kind of LED unit of direct heat radiation, it comprises LED and the aluminium base that a plurality of equally distributed row multirows or multiple row multirow are arranged, have the components and parts pin hole on the aluminium base, it scribbles thin heat conductive insulating layer on pin hole inwall and joint face that pin is connected, be printed with the connecting circuit of LED on it, LED is inserted and secured in the pin hole of aluminium base.
Above-mentioned described LED of the present utility model adopts four pin LED.
Three of the every row of above-mentioned described LED of the present utility model is one group, connects the back and connects a current-limiting resistance, is connected with another group again, and the pin of current-limiting resistance is inserted and secured in the pin hole of aluminium base.Six of the every row of LED is one group, connects the back and connects a current-limiting resistance, is connected with another group again, and the pin of current-limiting resistance is inserted and secured in the pin hole of aluminium base.
The LED wick that the LED unit that above-mentioned described the utility model directly dispels the heat is formed, it comprises polygon prism and socket, polygon prism is that the LED unit by three above-mentioned described direct heat radiations is fixed together by fixture and forms, be electrically connected between each LED unit that directly dispels the heat, socket is fixed on the upper end or the lower end of polygon prism by the socket seat.
The LED wick that the LED unit that above-mentioned described the utility model directly dispels the heat is formed, it is to be arranged to be fixed together by required angle by the LED unit of one or more above-mentioned described direct heat radiation to form, and is electrically connected between each LED unit that directly dispels the heat.
Because the utility model LED wiring board aluminium substrate, metallic aluminium and heat conductive insulating layer good heat dissipation effect, and the heat conductive insulating layer is extremely thin, has only 0.0065mm, and the pin that inserts interior LED of aluminium base and current-limiting resistance directly contacts aluminium base substantially, the heat that pin sheds is directly dissipated by aluminium base, its good heat dissipation effect has reduced the bulk temperature of wick, has slowed down the light decay of LED, increase the service life of LED, be more than 3 times of original LED service life.And the wick volume than LED unit that installs radiator structure in the wiring board back additional and composition thereof is little, light, and fixing simple, effective, manufacture craft is simple, has saved artificial.Circuit is printed on the heat conductive insulating layer of aluminium base, has guaranteed the reliability and stability of circuit.Directly the garden lamp and the Landscape Lamp wick of various polygon prisms can be formed in the LED unit of heat radiation, guaranteed the demand of people to shape.Directly the LED unit of heat radiation can be arranged in various street lamps by required angle again, guarantees the demand of people to various brightness street lamps.
