Description

LED type bulb heat radiation structure
Technical field
A kind of LED type bulb heat radiation structure, You Zhike reaches 360 degree illuminations and has the LED type bulb heat radiation structure of radiating effect concurrently.
Background technology
LED possesses characteristics such as life-span length, power saving, volume are little, no mercury pollution, meets the environmental protection demand, and along with the progress of chip encapsulation technology, application has been extended to purposes such as illumination and panel backlight gradually by indicator lamp.
LED excites chip and produces " light " and " heat " by the input electric energy, and with regard to present technology, light that disengages and ratio of specific heat example are about 25%:75% heat.
The light of LED and hot tool two big characteristics: the firstth, its light has directionality, its light emission direction is hemispherical, and the irradiating angle of LED be about 20 the degree, so the forward light of its direct projection is the strongest, but lateral light is fainter; The secondth, the too high meeting of temperature of working as it causes the phenomenon of light decay, therefore needs to strengthen heat radiation, to keep normal luminous flux.
The LED of common technology has two kinds, one is LAMP type spot light formula encapsulation (plug-in type), another is SMD type spot light formula encapsulation (surface stuck), wherein, distinguish with drive current, be divided into high-power (more than the running electric current 350mA) high-brightness LED again, it can send high light and high temperature, uses on bulb or street lamp mostly; And low-power (indication LED of running electric current 20mA~100mA), it sends the low light level, uses at signal lamp or blinker (as traffic lights, direction of traffic lamp) mostly.
The lamp envelope design of common technology all adopts this type of " spot light " LED, their common drawback, comprise the mode of taking " indirect lighting ", reduced the brightness of bulb, and huge " radiator ", limited the handsome in appearance of bulb, also increase manufacturing cost, and when many low current LED series connection and in parallel, circuit complexity and contact are many, fault rate is high, stability is poor, do not meet the characteristic of LED long service life, in sum, the LED bulb shortcoming of common technology is as follows:
1. most of bulbs are flattened on the radiator (heat sink) after all adopting great power LED (more than the 350mA) to cover " optical lens ", the LED outside covers the cloudy surface lamp housing of " hemispherical " again, the light that LED is sent arrives " cloudy surface lamp housing " through the refraction of " optical lens ", refraction spreads out of outside the lamp housing again, this kind design is to be " indirect lighting " through 2 refractions, refracting process can lose some brightness, and be subject to the packaged type of " point " light-source type and the lamp housing moulding of " hemispherical ", lighting angle is less, and lamp housing needs to adopt " cloudy surface ", lamp housing could produce the effect of refraction and slow fire, if use " transparent " lamp housing then can't produce refraction effect, thus shell limited be one of the shortcoming of this type of design.
2. the high-powered LED lamp generation high temperature of steeping oneself-meeting, need to use large-scale radiator (heat sink) to come auxiliary heat dissipation, influenced the handsome in appearance of bulb, its radiating mode, be to smear " heat-conducting cream " smooth being fixed on the radiator (heatsink) of casting with alumin(i)um zinc alloy or making with screw again below the LED with the aluminium extruded type lathe, " yet heat-conducting cream " itself is a kind of silica gel, its poor heat conduction, radiating effect is very limited, and alloy casting or with the made radiator of aluminium extruded type, volume is bigger, manufacturing process is loaded down with trivial details, and the LED bulb of every kind of size or external form all will be developed one group of mould, " time is long and fund cost is higher ", and this is another shortcoming of this type of design.
3. the bulb that combined of low-power " indicator type LED ", because " indicator type LED " is original to be not designed for throwing light on just, its outer enclosure material mostly is epoxy resin OXY greatly, can't shielding of ultraviolet, aging, non-refractory and heat radiation are difficult for easily, cause the brightness decay deficiency, and tens of and even LEDs up to a hundred series connection and when in parallel, the circuit complexity, contact is many, fault rate is higher, stability is relatively poor.
