Description

Electricity-saving lamp

Technical field

The utility model relates to the electricity-saving lamp technical field, relates in particular to a kind of electricity-saving lamp that improves the efficiency of light energy utilization.

Background technology

Present electricity-saving lamp kind is more, has plenty of directly to be coated with reflectance coating in the lampshade inner and outer surface layers, and what have is provided with plane or curved reflector at lampshade inner surface, because these structures are all complicated, thereby exist energy-saving effect unreliable, the industrial implementation difficulty is big, problems such as performance degree of controllability difference.It also is the LED lamp reflector of CN201203047Y just like publication number, comprise the reflector cover body, described reflector cover body is " ∏ " cup body structure, and described reflector cover body is the macromolecular material integrated formed structure, its cover body inwall is provided with reflectance coating, and the effect of this reflectance coating is a reflection ray.Though this structure can reduce reflection of light loss, still can't avoid the loss of part reflection of light, simultaneously, spraying process in addition in the process makes complex process, the manufacturing cost height.

The utility model content

The purpose of this utility model is: the electricity-saving lamp that a kind of light efficiency height, controllability are strong, simple in structure, be easy to industrial implementation is provided.

The technical solution of the utility model is: a kind of electricity-saving lamp, comprise illuminator, and be covered with the light harvesting conductor on the described illuminator.

The geometry of described light harvesting conductor is to be rotated a circle along the illuminator central axis by the total reflection curve to form, and, circle place face is same plane at the bottom of illuminator place face and the light harvesting conductor, the point on the illuminator and the ultimate range of its geometric center are illuminator radius r 1, radius of circle is r2 at the bottom of the light harvesting conductor, satisfies r1≤r2; Described total reflection curve is meant that the illumination of sending on all illuminators is mapped on this curve and all total reflection can takes place, and described illuminator central axis is meant through the geometric center of illuminator and perpendicular to the straight line of illuminator.

Because the illumination that illuminator sends is mapped on this reflectivity curve and all total reflection can takes place, and the refraction of light can not take place, and can not produce the loss of light, illustrates that so light efficiency of the present utility model is very high, has improved energy utilization ratio.Simultaneously, the geometry of this light harvesting conductor can determine that is to say provides reliable foundation to industrial production by curvilinear equation.Also have, the utility model not only need not be coated with reflectance coating at the light harvesting conductive surface, and total reflection all can take place in the light that shines the light harvesting conductor on all illuminators, the utility model has saved the technology of spraying reflectance coating in industrial production like this, make the utility model processing technology very simple, cost is low.

Described light harvesting conductor adopts fiber optic materials or optical material to make.

Described light harvesting conductor or employing PC or employing PC and PBT blend or employing glass are made.

Described illuminator is a disc.Illuminator radius r 1 is slightly less than disc radius r 2 at the bottom of the light harvesting conductor, and r1, r2 two circles at place respectively overlap (as shown in Figure 1) in concentric mode.

Described illuminator comprises red, green, blue at least that substrate and substrate be provided with monochromatic illuminator more than three kinds, and described each monochromatic illuminator is evenly distributed on substrate.The light that this illuminator sends is white light, and this is a kind of method of easy generation white light, provides approach easily to the raising of colour rendering.Certainly, can select one or more monochromatic light as required.

The beneficial effects of the utility model are: the light harvesting conductor has guaranteed that almost 100% luminous energy all passes through from the light harvesting conductive surface, has improved energy utilization ratio; Simple in structure, low cost of manufacture.

Below in conjunction with the drawings and specific embodiments the utility model is further specified.
