Abstract

The utility model relates to an energy-saving lampshade with an adjustable long wide focal length, which belongs to the new field of transplanting the principle of a camera to LED lighting, and comprises a special zooming optical lens for LED, an outer shell and the like. The lampshade is characterized in that the curvature radius of the outer arc-shaped surface of the special round, square or rectangular zooming optical lens for LED is ranged from R12 to 280mm. After being mounted, the high-efficiency energy-saving lampshade can concentrate the scattered light so as to improve the brightness, can be specially used in the scope most in need of lighting but is different from general torches and traditional spotlights, because the brightness of the torches and the traditional spotlights is concentrated in the minimum scope of lighting focusing on points, and the technical condensation scheme is for a medium scope of lighting focusing on surfaces. The energy-saving lampshade with the adjustable long wide focal length particularly adapts to the indoor and outdoor energy-saving lamps of various LEDs and various high-efficiency energy-saving lamps of industrial lamps and combined wide-angle street lamps.

Description

The energy-saving lamp shade of the wide focal length of a kind of adjustable length

Affiliated technical field

The utility model relates to the energy-saving lamp shade of the wide focal length of a kind of adjustable length, increases an extraordinary focal optical lens again in the dead ahead of LED emitting bulb exactly specifically, and the brightness that can improve light also can increase the distance of illumination, belongs to the special optical field.

Background technology

Traditional flashlight and remote spotlight, all be to come optically focused by the circumference of side or the refractive body around the side, the effect of institute's optically focused is the remote floodlighting based on point, but not enough is that lighting area is big inadequately when being used for room lighting, as when reading of writing as desk lamp because light will injure eyes too by force, as area is wide inadequately when being used for outdoor street lighting, produces bigger lighting blind zone at the intersection of 2 street lamps.

Summary of the invention

Too concentrated in order to overcome traditional optically focused lampshade focal point, the weak point that lighting area is big inadequately, the demand that can not adapt to homalographic illumination in other multiple occasion, the purpose of this utility model is exactly the pancratic optical lens technology essential factor of camera, graft application is on the frontier of LED illumination, the technical scheme of homalographic in a kind of can the gathering the light source of LED astigmatism equably is provided, exactly the slide in lampshade dead ahead outside is all changed into the cambered outwards solid cambered surface of radius of curvature between R12～280mm, inner face should be according to different occasions to lighting area and brightness of illumination, the different demands of illumination distances, the convex globoidal of different spheres between employing R18～180mm, the extraordinary focal optical lens of the LED special use on cancave cambered surface or plane.The camera lens peripheral size of the extraordinary zoom optics of LED special use is just used between diameter phi 38～200mm or the appearance and size between width 28～200mm.By above-mentioned improvement, after just only needing the zoom blast of astigmatic bulb by the extraordinary focal optical lens of dead ahead LED special use with smaller power, use in needing most, the illumination of small size or farther distance, just can satisfy desk lamp 1 rice and flour as LED bulb and be equivalent to the soft light of 25w astigmatism incandescent lamp in long-pending, thereby just can reach many times of purpose of energy saving with 1W.

The beneficial effects of the utility model are: Gong Ying various bulbs and illuminating LED luminous lamp tube generally all are astigmatic type or accumulation type in the market, the light angle of astigmatism is at least at 180 ° of degree, its top luminous energy has still been wasted, the technical solution of the utility model is exactly that middle homalographic that the large tracts of land of 180 ° of degree astigmatism are gathered 90 ° of degree just can blast more than 3 times, as the area of the 45 ° of degree that reassociate just can increase by 3 times brightness again, at this moment just can reduce the power of bulb more than 9 times, can also reach the local luminance of original light diffuser, just lighting area reduces 9 times, thereby just can reach the beneficial effect of 9 times of economize on electricitys.
