Description
Technical field
The utility model relates to technical field of semiconductor illumination, particularly relates to a kind of LED street lamp lamp holder with extra long life.
Background technology
Electric energy conversion, referred to as LED, be a kind of can be the semiconductor electronic component of luminous energy by light emitting diode.LED is called as forth generation light source, and because having, electric light transformation efficiency is high, environmental protection, volume is little, brightness is high, be easy to light modulation, start and be widely used in the field such as general lighting, street lighting without features such as time delays.
At present, LED chip operationally has only has 30-35% electric energy conversion to become luminous energy, in addition 65-70% changed into heat energy.LED, to responsive to temperature, in general, just can avoid hydraulic performance decline even to lose efficacy at junction temperature less than 125 degrees Celsius LED.According to statistics, in use to have the fault of more than 70% to come from LED temperature too high for LED.In addition, the components and parts such as the driving power of LED are also to responsive to temperature, and too high operating temperature can cause decline fast the service life of drive unit.Thus, heat dissipation problem is to become a key factor in restriction LED lamp service life.
Summary of the invention
For problems of the prior art, the purpose of this utility model is the LED street lamp lamp holder providing a kind of good heat dissipation effect, long service life.
For reaching above object, the utility model adopts following technical scheme.
There is a LED street lamp lamp holder for extra long life, it is characterized in that, comprising: housing, be embedded in the flat superconducting heat pipe in housing, and the some LED lamp bead be arranged on flat superconducting heat pipe and drive unit.
Further illustrating as such scheme, described flat superconducting heat pipe is tabular, in flat superconducting heat pipe, be provided with liquid-sucking core, and liquid-sucking core forms the steam flow channel of multiple parallel arrangement.
Further illustrating as such scheme, the shape of described housing is butterfly-like, dragonfly shape or leaf shape.
Further illustrating as such scheme, is extended with radiating fin in housing surrounding, forms convection channel between adjacent heat radiation fin, and the air-flow direction in convection channel is vertical with the LED lamp bead installed surface of flat superconducting heat pipe.
Further illustrating as such scheme, is provided with plane minute surface reflecting piece around each LED lamp bead.
Further illustrating as such scheme, is provided with circular port in the centre of minute surface reflecting piece, and described LED lamp bead passes from circular port; Pin mounting groove is provided with around circular port.
Further illustrating as such scheme, housing is provided with lampshade, and described minute surface reflecting piece is fixed on around LED lamp bead by lampshade; Lampshade is provided with the lens corresponding with each LED lamp bead.
Compared with prior art, the beneficial effects of the utility model are:
One, by arranging flat superconducting heat pipe on housing, and LED lamp bead and drive unit being all arranged on flat superconducting heat pipe, effectively improving the radiating effect of LED lamp bead and drive unit, greatly extend the service life of whole light fixture.Through experiment test, utilize the LED street lamp lamp holder that the utility model is obtained, its service life is more than 2 times of conventional aluminum shell lamp holder.
Two, radiating fin be arranged on the surrounding of housing and form the bionical shapes such as butterfly, utilizing the radiating principle of bionical biology itself to accelerate the heat radiation of street lamp, not only radiating effect is excellent, and base shapes is attractive in appearance, and practicality is good.
Three, by arranging minute surface reflecting piece around LED lamp bead, improve the overall light efficiency of light fixture, reduce power consumption, and then reduce the caloric value of whole light fixture, extend light fixture service life further.
