Description
Technical field
The utility model relates to light emitting diode (being called for short LED) technology, is a kind of LED lamp pearl that has independent radiator specifically.
Background technology
In the traditional lighting technology, use osram lamp more, because power consumption and volume is big, luminous efficiency is low, the life-span is short, and more and more can not adapt to the needs of modern society.Development of semiconductor thereupon, the application of LED in electric light source technology that power consumption and volume are little, luminous efficiency is high, the life-span is long more and more is subject to people's attention.The general single power of LED lamp pearl all is smaller, and brightness is not enough, and in order to improve brightness, people often are used as a light source with a plurality of LED lamp pearl combinations and use synchronic being fixed on a circuit board and the radiator.Brightness of LED lamp pearl and life-span and its contact temperature are to have certain relation, and the LED radiating effect is good more, and operating temperature is low more, and brightness is high more, and the life-span is long more.Along with the LED improvement of Manufacturing Technology, what single led power can have been done now is increasing, during a shared fin, radiating effect is relatively poor, particularly when any large-power LED light bead is overheated, this heat can improve the temperature of monoblock fin, thereby has lowered the function of fin heat radiation, even might cause the too high even breaking-up of temperature of other lamp pearls.
Summary of the invention
The purpose of this utility model provide a kind of can be rapidly with transfer of heat, reduce the contact temperature, improve brightness, increase the service life, be single use or be used in combination the LED lamp pearl that has independent radiator that all has better heat dispersion.
The utility model is realized by following technical proposals:
A kind of LED lamp pearl that has independent radiator comprises the LED illuminator, and the potting resin of packaged LED illuminator, LED illuminator are installed on the side of circuit board, it is characterized in that: be provided with the column radiator structure on the opposite side of described circuit board.
Described radiator structure is by a cylinder and be evenly distributed on the strip shape body that the cylinder outer peripheral face is divergent shape and constitute, between the two adjacent strip shape bodies of same circumferential cross-section, be provided with the gap, also be provided with the gap between the two adjacent strip shape bodies of the axial direction of cylinder, the axial line of radiator structure overlaps with the axial line of LED illuminator.
In order to improve spotlight effect, also be provided with light-gathering optics lens in the front portion of described LED illuminator.
The utlity model has following advantage:
1. owing on the circuit board of fixed L ED illuminator, be provided with the column radiator structure; that is to say that each LED lamp pearl all is installed on the radiator structure of an independent isolating; therefore can be apace with transfer of heat; reduce the contact temperature of LED illuminator; so brightness that can improve LED; prolong the service life of LED; when particularly being used in combination; heat abstractor is not a shared fin; therefore the overheated influence to other LED illuminator of any LEDs illuminator is little; even have a LEDs illuminator or some LED illuminator heats too high, before heat can flow to other LED illuminator, light fixture can be taked power-off protection; this shows; LED lamp pearl with independently having radiator can effectively solve the problems of excessive heat of LED lamp pearl, can not impact other LED lamp pearl.
Since radiator structure by cylinder be evenly distributed on the strip shape body that the cylinder outer peripheral face is divergent shape and constitute, between the two adjacent strip shape bodies of same circumferential cross-section, be provided with the gap, between the two adjacent strip shape bodies of cylinder axial direction, also be provided with the gap, the axial line of radiator structure and circuit board central lines.Cylinder becomes a bulk of solid core heat sink material and is positioned over central authorities, thereby can remove the heat of the LED lamp pearl that has independent radiator apace, be the setting of the strip shape body of divergent shape, and also be provided with the gap being provided with between the two adjacent strip shape bodies of same circumferential cross-section between gap and the two adjacent strip shape bodies at the cylinder axial direction, increased the surface area of heat abstractor like this, thereby can in very short time, heat be spread in the ambient air, the structural design in these gaps, also make the circulation of air inside heat abstractor apart from shortening, heat is easier to loose, therefore, hot-air just can not be trapped in the heat abstractor the inside yet, but slips away together with other peripheral air apace.
3.LED when the lamp pearl was used in combination, the design of radiator structure not only allowed a lot of strip shape bodies arrange very compactly in very little scope, also made each LED lamp pearl radiator structure have big as far as possible area simultaneously.The diameter of each LED lamp pearl radiator structure and sectional dimension can be adjusted accordingly according to the setting angle of distance between LED lamp pearl and the LED lamp pearl or LED lamp pearl.
4.LED the front portion of illuminator is provided with light-gathering optics lens, so LED lamp pearl has the performance of optically focused, improves illumination efficiency.
