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, comprise the lamp holder connecting successively, drive circuit, radiator, LED substrate, a plurality of LED lamps and lampshade, its LED substrate is mostly plane layout in lampshade, being arranged on like this light that the LED lamp on LED substrate sends can only propagate towards a direction, and being an angle transmission to lampshade, the light that LED lamp sends goes out, and because LED lamp is mainly that concentrated setting is in LED substrate central region, so region below LED light-illuminating angle, such as LED substrate with lower area etc., be mostly unglazed region, the illuminating effect of LED lamp is affected, therefore, expand the irradiating angle of LED lamp, improve illuminating effect, 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 LED lamp 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, lens 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 lens are arranged on LED lamp central region, described lampshade is located at described LED lamp and lens top, described lens comprise a cylindrical body, the described cylindrical body top formation reflecting surface that caves inward, cylindrical body surrounding is exit facet.
Further, described reflecting surface is arcwall face.
Further, described lens cross-sectional area is about the 1/2-3/4 of LED lamp surface area.
Further, described lens cross-sectional diameter is about 32mm-35mm.
Further, described lens and this LED lamp coaxially arrange.
Further, described exit facet is provided with a plurality of polygon projections, and described polygon projection is uniformly distributed in described exit facet and forms alveolate texture, more even after light is penetrated.
The utility model is by adopting technique scheme, and compared with prior art, tool has the following advantages:
The utility model adopts the subregion on LED lamp that one cylinder lenses is set, and this cylinder lenses top caves inward and forms a reflecting surface, cylindrical body surrounding is exit facet, the light sending when LED lamp reflects downwards while arriving reflecting surface, illuminate the region below LED substrate, expand the irradiating angle of LED lamp, improve illuminating effect, make the unglazed region of LED less.
Accompanying drawing explanation
Fig. 1 is the partial sectional 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.
As a specific embodiment, as shown in Figure 1, a kind of LED lamp of the present utility model, comprise lamp holder 1, drive circuit, cylinder connector 2, radiator 3, LED substrate 4, a plurality of LED lamps 5, lens 6 and lampshade 7, 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 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 1 is arranged on this LED substrate 4, described lens are arranged on LED lamp 5 central region, described lampshade 7 is located at described LED lamp 5 and lens 6 tops, described lens 6 comprise a cylindrical body, described lens 6 cross-sectional areas can be designed to be about 1/2 of LED lamp surface area, be that described lens 6 cross-sectional diameters are about 32mm-35mm.And described lens 6 coaxially arrange with this LED lamp 5.Described cylindrical body top caves inward and forms reflecting surface 61, described reflecting surface 61 is arcwall face, cylindrical body surrounding is exit facet 62, and described exit facet 62 is provided with a plurality of polygon projections, and described polygon projection is uniformly distributed in described exit facet and forms alveolate texture.It is more even after light is penetrated.By the structure of said lens 6 and the setting of position thereof, make the irradiating angle of the lens of the present embodiment can reach 151 ° of * 2=302 °.
Described lens 6 cross-sectional areas can also be designed to be about 1/2-3/4 of LED lamp surface area.What make LED lamp can not affect illuminating effect when expanding irradiating angle.
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.
