Description
Technical field
The present invention relates to LED luminescence technology, more specifically, the present invention relates to a kind of LED lamp structure.
Background technology
Compare with high-pressure mercury lamp with existing incandescent lamp, fluorescent lamp, LED light source have efficiently, feature that environmental protection and life-span are long.But the people of conventional LED can find, LED light brightness is large especially, is easy to make luminous energy become heat energy, makes LED awfully hot.At this moment, if LED can not be dispelled the heat as early as possible, its life-span will reduce greatly.A lot of LED producer adopts aluminium shell to LED lamp, and aluminium shell easily dispels the heat, and can increase the life-span of wick, makes LED seem attractive in appearance.But aluminum Lamp cup cost is somewhat expensive, cost of manufacture is very high, and Lamp cup needs to process with lathe.
In addition, LED light source generally comprises the square LED component be located on heat-radiating substrate, LED component is usually in neat matrix arrangement, the heat-radiating substrate skewness of opposing circular shape, even if be evenly distributed, because focus is inconsistent, emergent light face is caused to there is the problem of non-uniform light, and a large amount of layout LED component can cause cost increase, heating improves further and causes the interactive life-span to decline.
Current, in order to improve irradiating angle, expanding irradiated area, two pieces of independently lamp housings being provided, being interconnected, realize by the angle adjusting lamp housing the object adding large illuminating angle, but multiple lamp housing cost of manufacture is higher.Existing also exist in the periphery plane of rectangle plane lamp housing peripheral disposition compared with mitre, although this plane can expand irradiated area and angle, there is part light and penetrate energy comparatively greatly, part light penetrates the less situation of energy, is unsuitable for civilian or road lighting.
Summary of the invention
For overcoming the above-mentioned defect of prior art, the present invention proposes a kind of LED lamp structure.
According to an aspect of the present invention, propose a kind of LED lamp, comprise vertical lamp socket, LED light source and optical lampshade, optical lampshade is arranged on the front end of lamp socket, LED light source is arranged on lamp socket, and LED light source comprises conical heat-radiating substrate, and heat-radiating substrate is evenly arranged LED component; Between heat-radiating substrate and lamp socket, hemispherical reflecting plate is arranged in cross-over connection.
The invention enables LED component to facing away from substrate, and pass through the effect of expelling plate or speculum, both played the effect that light diffuses to a distant place, and played again heat radiation and act on faster.After aluminium sheet, arrange metal accessory plate, accelerate heat radiation further.In addition, adopt detachable layout LED component, make LED lamp to install quickly and easily or to change.
Accompanying drawing explanation
Fig. 1 is the structural representation according to LED lamp of the present invention.
As shown in the figure, in order to the structure of embodiments of the invention clearly can be realized, specific structure and device are marked in the drawings, but this is only signal needs, be not intended to limit the invention in this ad hoc structure, device and environment, according to specific needs, these devices and environment can carry out adjusting or revising by those of ordinary skill in the art, and the adjustment carried out or amendment are still included in the scope of accompanying claim.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, a kind of LED lamp structure provided by the invention is described in detail.In the following description, by description multiple different aspect of the present invention, but, for those skilled in the art, can only utilize some or all structure of the present invention or flow process to implement the present invention.In order to the definition explained, set forth specific number, configuration and order, but clearly, also can implement the present invention when there is no these specific detail.In other cases, in order to not obscure the present invention, will no longer be described in detail for some well-known features.
Fig. 1 illustrates the structure according to LED lamp of the present invention, comprise vertical lamp socket 1, LED light source 2 and optical lampshade 3, optical lampshade is arranged on the front end of lamp socket, LED light source is arranged on lamp socket, LED light source comprises conical heat-radiating substrate 4, the front-end-cone point of heat-radiating substrate stretches out facing to optical lampshade, heat-radiating substrate is evenly arranged LED component 5.Arrange hemispherical reflecting plate between the rear end cone seat of heat-radiating substrate and lamp socket, cone seat extends in lamp socket, and the sealing of hemispherical reflecting plate is connected across therebetween.
In another embodiment, heat-radiating substrate is biconial, and its front-end and back-end are all cone point, rear end cone point extends to lamp socket inside, like this, and the luminous direct projection of front-end-cone point, the LED luminescence of rear end cone point, by hemispherical baffle reflection, strengthens luminous uniformity further.
Wherein, this LED light source comprises the heat-radiating substrate of taper shape, hollow, and the end rear of heat-radiating substrate or side have passage, arranges the passage being communicated with hollow around front-end-cone point LED component.
In one embodiment, arrange optical reflective devices on reflecting plate surface, strengthen reflection efficiency further.In one embodiment, reflecting plate uses aluminium sheet.
In one embodiment, reflecting plate uses pottery, arranges optical reflective devices, thus reduce costs in interior ceramic surface.
In one embodiment, the LED component on heat-radiating substrate can be divided into multiple region, such as four, six, needs to adjust respectively to cut-off according to luminescence.
In one embodiment, exiting parallel or outside diffusion emitter when the position LED emergent light of reflecting plate reflexes on reflecting plate.
In one embodiment, LED driver part is arranged in lamp socket, and lamp socket is that vertical height is adjustable, and lamp socket comprises support bar portion, and this support bar portion arranges gauge tap.
Finally it should be noted that, above embodiment is only in order to describe technical scheme of the present invention instead of to limit this technical method, the present invention can extend in application other amendment, change, application and embodiment, and therefore think that all such amendments, change, application, embodiment are all in spirit of the present invention and teachings.
