Description
Technical field
The utility model relates to the outdoor lighting technical field, specifically a kind of LED light fixture.
Background technology
As everyone knows, along with semiconductor technology constantly develops, the LED semiconductor light sources, as energy-conserving light source, is now paid attention to by government agencies at all levels gradually, and existing a small amount of application, become the third generation lighting source after the lightings such as incandescent lamp, fluorescent lamp aspect street lamp or shot-light illumination.But its characteristic requirements of high-power LED light source, the heat that LED light source must be produced during work is derived in time; Because the LED light source distribution is smaller, need carry out secondary optical design to its light source, avoid LED street lamp or shot-light luminous too concentrated.Above-mentioned two problems have now become the bottleneck that LED light source develops aspect street lamp or shot-light illumination.
In addition, for the traditional heat-dissipating structure, in order to increase radiating efficiency, increase area of dissipation blindly, as increased fin etc. on radiator, heat transmits inhomogeneous, can not effectively improve radiating efficiency, also increase that the LED light fixture is integrally-built to take up room simultaneously; Another key factor that two, radiating efficiency is low is not paid attention to; that is exactly current thermoelectricity integral structure; it is the respective pin place that the both positive and negative polarity of LED and the end that conducts heat all are connected to circuit board; the end that conducts heat need to just can transfer heat to radiator by insulating barrier, substrate, conduction oil; its radiating efficiency is lower; this version can cause the end heat accumulation that conducts heat usually, and LED very easily damages.In any case, so improve radiator, the structure that does not change this thermoelectricity one just can't fundamentally solve heat dissipation problem.
Summary of the invention
The purpose of this utility model is to provide a kind of LED energy-saving lamp.The utility model is the uniform irradiation by alveolate texture by the light source reverberation bowl, the hot spot of fundamentally eliminating.
The purpose of this utility model is achieved in that it includes housing, substrate, LED, the light source reverberation bowl, radiating tube, transparent lamp shade, its technical essential is: be evenly distributed with the light source reverberation bowl structure of disjunctor on the convex surface of arc heat-conducting substrate, each light source reverberation bowl inboard is provided with a LED, the rearward end of this LED is connected with the arc heat-conducting substrate, and the edge of light source reverberation bowl structure is the cellular regular hexagon structure of convex surface; Some heat radiations chamber is set on the concave surface of described substrate, and this heat radiation chamber is communicated with formation single loop structure with the radiating tube of described substrate outside, described heat radiation chamber and heat radiation casing pack cold-producing medium; LED in the light source reverberation bowl is connected in series mutually.
Described heat radiation chamber and described substrate are the integral type structure.
Described substrate is aluminum base plate, aluminium alloy substrate processed, copper substrate, ceramic substrate or composite metal substrate.
The nickel dam that integral surface plating one deck of described substrate has the wear-and corrosion-resistant effect.
The utility model is due to the cellular regular hexagon structure of the edge employing convex surface of the light source reverberation bowl structure at uniform disjunctor, to making once light and being radiated at equably on road or wall through the secondary light that the light source reverberation bowl forms, when this structure is arranged on 8 ~ 10 meters high road surfaces, its illumination length is at 50 ~ 65 meters, irradiating width is at 12 ~ 16 meters, and do not produce any hot spot or shadow.
Radiator structure of the present utility model improves the initial luminous flux of LED, and the time lengthening that luminous flux attenuation is initial luminous flux 70%, extend the service life that is LED, adopted the LED light fixture of photodetachment structure in the situation that LED quantity is constant, and its brightness improves greatly.Change angle, reach the situation with original design same brightness, can reduce the usage quantity of LED, also just reduced the production cost of LED light fixture.
The utility model also has simple and reasonable, safe and reliable, and cost is low, long service life, the characteristics such as range of application is wide.
