Description
Technical field
The utility model relates to LED lighting field, in particular to a kind of LED Projecting Lamp.
Background technology
Common LED Projecting Lamp is made up of five parts such as light source, reflective surface, cover plate, electric component, housings conventionally in the market.The light source adopting has Metal halogen lamp, the integrated lamp plate of LED etc.Be characterized in: the light projecting is at illuminated body surface, form a fan-shaped shadow surface, the fan-shaped irradiation area projecting and rectangular (or approximate rectangular) lighting object are inconsistent, cause more light waste and the light of adjacent non-field of illumination is polluted, cause luminous energy to be wasted, accordingly electric power resource is also caused to waste.
Utility model content
The purpose of this utility model is to provide a kind of LED Projecting Lamp, to solve the above problems.
The LED Projecting Lamp that the utility model provides, comprise lamp plate and convex lens, described lamp plate is arranged on described LED Projecting Lamp end, described convex lens are arranged on the opening of described LED Projecting Lamp front end, the geometric center of described convex lens and the geometric center of lamp plate are on the same line, described lamp plate is parallel with described convex lens, and described lamp plate is trapezoidal.
By convex lens being installed at LED Projecting Lamp front end, realize the light source sending from lamp plate is reflected, utilize the refractometer of light to calculate the trapezoidal size of lamp plate.By controlling trapezoidal shape, can realize at LED Projecting Lamp and surface to be irradiated when angled, to the accurate irradiation of rectangular band irradiation area.
Further, the edge of described lamp plate is circular arc.The edge designs of lamp plate is become to circular arc, can effectively make up the error that in actual fabrication, LED Projecting Lamp edge produces.In practical engineering application, due to often imperfect convex lens also of convex lens, the shadow projecting can not make straight line at edge, but occurs arc or outer arcuate.At this moment based on light path principle of reversibility, lamp plate also will be done and be processed strain type is contrary.
Further, the distance of described lamp plate and described convex lens is less than the focal length of described convex lens.Lamp plate is less than the focal length of described convex lens to the distance of convex lens.Lamp plate is less than the focal length of convex lens to the distance of convex lens, according to convex lens imaging principle, if the distance of convex lens and lamp plate is u, make the shadow launched just illuminated region surface form one clearly as, will there is the picture of each LED chip on lamp plate itself in the shadow of launching so.At this moment, should adjust u to u ', make u ' < u, and on the lamp plate that makes to launch, the image depth of each LED chip itself defocuses diffusion and merges mutually.According to image-forming principle, one-tenth be fuzzy inverted image, virtualization single led illumination precision, make the image of irradiation area more even, integral illumination better effects if.
Further, described convex lens are Fresnel convex lens.Adopt Fresnel convex lens no matter refraction effect is good, thin thickness simultaneously, is conducive to can also ensure enough light transmittances in the case of reaching identical refractive index, can not make the illuminating effect of light reduce.
Further, the LED on described lamp plate is equal-difference arrangement from top to bottom.The LED that equal-difference arrangement distributes, the decay according to light at surface to be irradiated, distributes, and can make the brightness value of LED on surface to be irradiated, irradiate distribution more even.
The beneficial effect that the utility model provides is, increase convex lens by the front end at LED Projecting Lamp, realize LED light can be reflected LED Projecting Lamp, coordinate trapezoidal lamp plate, can realize in the angled situation of Projecting Lamp and region to be illuminated, rectangle region to be illuminated is accurately irradiated.
