Description
Technical field
The utility model relates to LED lighting field, is specifically related to a kind of LED lamp.
Background technology
LED(light emitting diode) be a kind of solid-state semiconductor devices that can be visible ray by electric energy conversion, it can directly be converted into light electricity, and, life-span length, environmental protection, fast response time energy-conservation with it, can start rapidly, the advantage such as convenient transportation and installation, and be widely used in home lighting.
Existing LED lamp adopts hemispherical lampshade mostly, and LED substrate is mostly plane layout in lampshade one side, being arranged on like this light that the LED lamp on LED substrate sends can only propagate towards a direction, and the light that LED lamp sends forms transmitting when arriving globe holder, to illuminate the region of the following part of LED substrate, but due to stopping of the radiator of LED substrate and some larger shapes, always some is to belong to unglazed region to make LED lamp, in order to improve the illuminating effect of LED lamp, the irradiating angle that expands LED lamp, just must make the unglazed region of LED more little more excellent.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of irradiating angle that can expand LED lamp, and the unglazed region of LED lamp is greatly reduced, thereby reaches the object that improves illuminating effect.
In order to achieve the above object, the technical scheme that the utility model adopts is a kind of LED lamp, comprise lamp holder, drive circuit, cylinder connector, radiator, LED substrate, a plurality of LED lamps and lampshade, in described lamp holder, be provided with drive circuit, described LED drive circuit is connected with described LED electrical property of substrate, described cylinder connector one end is connected with described lamp holder one end, the described cylinder connector other end is connected with one end of described radiator, described radiator is provided with LED substrate, described a plurality of LED lamp is arranged on this LED substrate, described lampshade is located at described LED lamp top, the end face of described lampshade is a plane, lampshade periphery is cambered outwards arcwall face, lampshade inner surface is provided with the reflecting layer of minute surface.
Further, described radiator comprises a cylinder, described cylindrical cross-section is less than described LED substrate surface, and described cylindrical periphery is uniformly distributed and is provided with a plurality of radiating fins, described in each, the outer, top of fin is no more than LED substrate outer, and the middle part of this radiating fin outwards protrudes out, form and be roughly trapezoidal heat radiation fin structure.
Further, described in each, radiating fin is vertical with this periphery.
Further, described cylinder connector is heat-conducting plastic cylinder connector.
The utility model is by adopting technique scheme, and compared with prior art, tool has the following advantages:
LED lamp of the present utility model, having adopted an end face is a plane, lampshade periphery is the lampshade of cambered outwards arcwall face, and lampshade inner surface is provided with the reflecting layer of minute surface, when the light that the LED lamp on LED substrate sends is radiated in the plane above LED lampshade, can effectively be reflected, and its reflection angle is significantly smaller than the reflection angle of hemispherical lampshade, and because adopting, LED lamp of the present utility model is similar to trapezoidal radiating fin, the top of this radiating fin is no more than this LED substrate outer, make the LED light of reflection can pass through smoothly this subregion, and can not stopped by radiator.
Accompanying drawing explanation
Fig. 1 is the front view of LED lamp of the prior art;
Fig. 2 is the front view of embodiment of the present utility model.
The specific embodiment
Now with the specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
For technical scheme and the technique effect of the present embodiment are better described, first LED lamp of the prior art being done to one analyzes simply, shown in figure 1, LED lamp of the prior art, comprise lamp holder 10, in lamp holder 10, be provided with drive circuit, lamp holder 10 is provided with radiator 20, radiator 20 is provided with LED light source, on LED light source, be covered with lampshade 30, shown in lampshade 30 be hemispherical lampshade, when irradiation that LED light source sends is on lampshade 30, arcwall face through hemispherical lampshade top reflects with larger angle of reflection, therefore caused compared with the formation in the unglazed region 40 of wide-angle, and because its radiator 20 shapes of LED lamp of the prior art are larger, also easily block a part of reflection ray, light angle and the illuminating effect of whole LED lamp are affected.
As a specific embodiment, as shown in Figure 2, a kind of LED lamp, comprise lamp holder 1, drive circuit, cylinder connector 2, radiator 3, LED substrate 4, a plurality of LED lamps 5 and lampshade 6, in described lamp holder 1, be provided with drive circuit (not shown), described LED drive circuit and described LED substrate 4 are electrically connected, described cylinder connector 2 is heat-conducting plastic cylinder connector, adopt the cylinder connector of heat-conducting plastic material, can effectively reduce the weight of the LED lamp in the present embodiment, make whole lamp body lightly convenient, described cylinder connector 2 one end are connected with described lamp holder 1 one end, described cylinder connector 2 other ends are connected with one end of described radiator 3, described radiator 3 is provided with LED substrate 4, described a plurality of LED lamp 5 is arranged on this LED substrate 4, described lampshade 6 is located at described LED lamp 5 tops, the end face of described lampshade 6 is planes 61, lampshade 6 peripheries are cambered outwards arcwall face 62, lampshade 6 inner surfaces are provided with the reflecting layer (not shown) of minute surface.When light that LED lamp 5 sends propagates in the plane 61 of lampshade 6, because the reflection angle of plane is less, so the reflection ray of this LED lamp reflects with less emission angle, from the edge of LED substrate, outwards launch, and in the present embodiment, described radiator 3 comprises a cylinder 31, described cylinder 31 cross sections are less than described LED substrate 4 surfaces, and described cylinder 31 peripheries are uniformly distributed and are provided with a plurality of radiating fins 32, described in each, radiating fin 32 is vertical with these cylinder 31 surfaces, described in each, the outer, top of fin 32 is no more than LED substrate 4 outers, and the middle part of this radiating fin 32 outwards protrudes out, form and be roughly trapezoidal heat radiation fin structure.The design of such radiating fin, can not stopped by LED radiator 3 and radiating fin 32 light of reflection, can pass through smoothly, and the scope in unglazed region 7 is reduced greatly, has expanded dexterously irradiating angle and the illuminating effect of LED lamp.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; within not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
