Description
Technical field
The utility model relates to lighting technical field, particularly relates to a kind of fin-type LED.
Background technology
LED, i.e. light emitting diode (LightEmittingDiode), being a kind of New Solid light source of new century most development power, is a kind ofly utilize semiconductor PN that electric energy conversion is become luminous energy and have the electronic device of diode characteristic.Because LED has energy-conservation, the advantages such as the life-span is long, environmental protection are very popular, but the radiating effect of LED is poor, and this limits the development of LED always.The wick of LED is the core of LED, and the wick place due to LED concentrates quantity of heat production comparatively large, and in order to ensure the life-span of wick, heat radiation is particularly important, particularly some high-powered LED lamps, and how high efficiency and heat radiation then becomes people's problem demanding prompt solution.
Utility model content
Technical problem to be solved in the utility model provides a kind of stability strong, the fin-type LED of good heat dissipation effect.
For achieving the above object, the utility model provides following technical scheme:
A kind of fin-type LED, include lamp holder, radiator and wick, described lamp holder is connected with radiator, and described lamp holder inside is provided with drive circuit board, is provided with power contacting plate bottom described lamp holder, and described lamp holder external bottom end is provided with multiple louvre; Described radiator is fin-type; by organizing fin around being rolled into hemispherical more; described radiator inside is disposed with containment vessel from top to bottom; wick; insulating ceramics lamella; upper metal conductor layer; semiconductor layer and lower metal conductor layer; the transparent disc-shaped of described containment vessel, described wick connects drive circuit board by cable, and described lower metal conductor layer connects fin; described radiator top is connected with retainer ring; be provided with between described retainer ring and containment vessel and organize reflecting piece more, described reflecting piece is billet type, is close to around arrangement.
As the improvement of the above-mentioned fin-type LED of the utility model, described power contacting plate quantity is two.
As the further improvement of the utility model above-mentioned fin-type LED, described multiple louvre arranges around lamp holder bottom.
As the further improvement of the above-mentioned fin-type LED of the utility model, described semiconductor layer is arranged side by side alternately by two kinds of semiconductors and forms.
Compared with prior art, the utility model has the advantage of: described fin-type LED have employed double-radiation function compared to traditional fin-type LED, outside fin type radiator is dispelled the heat in internal heat divergence to air by fin; The inner thermoelectric cooling technology that adopts is dispelled the heat, namely the thermocouple of the semiconductor composition of two kinds of different materials is connected with dc source, when electric current flows through two semiconductors, two contact places there will be the phenomenon of heat absorption and release, one end of heat absorption forms cold junction, the formation hot junction, one end of heat release, the wick of LED presses close to cold junction, the heat that wick produces is passed to cold junction and is absorbed by cold junction, hot junction liberated heat scatters and disappears by connecting external heat sink, described insulating ceramics lamella is cold junction, and described lower metal conductor layer and fin type radiator are hot junction; Described fin-type LED stability is strong, good heat dissipation effect.
