Abstract
The utility model provides an LED (Light Emitting Diode) conical-face cup-shaped condensing lens. The LED conical-face cup-shaped condensing lens comprises a cup-shaped body, wherein one end of the cup-shaped body serves as a top face, the other end of the cup-shaped body serves as a bottom face, a conical concave pit is formed in the bottom face, the bottom face of the conical concave pit serves as an entrance face of the condensing lens, a concave hole is formed in the top face of the cup-shaped body, the bottom face of the hole serves as an exit face of the condensing lens, and an outer circular ring is arranged at the edge of the top face of the cup-shaped body. The LED conical-face cup-shaped condensing lens has the advantages that light is subjected to once condensing on a convex face so as to enable projection shapes of light spots to be circular, and the divergence angle of the light in the lens is 20 degrees, so that concentrated irradiation of light is realized; honeycomb-shaped small bulges are arranged on the entrance face, so that the uniformity of the light is improved, and the light spot projection is enabled to be uniform; LED chips are adopted as light sources, so that the energy consumption is low, the size is small, the service life is long, and the maintenance cost is low; and the LED conical-face cup-shaped condensing lens is a single small lens, so that multiple LED conical-face cup-shaped condensing lenses can be mounted in a combination manner, thereby enabling lamp design to be simpler and more reasonable.
Description
Technical field
The utility model belongs to and relates to the LED light source lighting field, particularly a kind of collector lens for the LED uniform irradiation.
Background technology
Illuminating lamp at the sight spot, park, the exhibition of interior decoration, guild hall all has indispensable effect.Played the effect of playing up atmosphere, decorating view, beautify the environment.For meeting lighting demand, people still adopt traditional illumination lamp.One of its topmost shortcoming is that power consumption is high.As incandescent lamp, it is interior energy that its principle is based on electric energy conversion, and next luminous by heating, its electric energy almost completely is converted into heat, causes luminance shortage, and the life-span is short, and it also fails to reach the requirement of current low-carbon environment-friendly far away.
Although existing lamp source adopts the LED lamp more, also have certain disadvantages.The bright dipping of existing LED lamp is affected by the LED encapsulation technology, the impact of lens in addition, general LED lamp lens make light source its central light strength after luminous intensity distribution high, the angle of divergence is little, but because the convex lens of backend arrangement easily cause the segment chip imaging, making hot spot is not the circle of standard, and this just causes light extraction efficiency poor, brings visual fatigue.
General practical light fixture is that integral type is made, and after certain part is damaged, can only integral body scrap.
After analysis-by-synthesis, can be summarized as: existing collector lens, the color spot moulding is poor, and light efficiency is poor, and the light source power consumption of use is large, installs loaded down with trivial details.
The utility model content
In order to overcome the problems referred to above, basis is novel provides a kind of LED conical surface cup-shaped collector lens, the conglobate uniform light spots of energy shape, and light transmittance efficiency is good, environmental protection, for convenience detach and installation.
In order to achieve the above object, be achieved through the following technical solutions:
The cup-shaped collector lens of a kind of LED conical surface, comprise a glass type body, one end of described cup type body is that the end face other end is bottom surface, described bottom surface arranges a tapered pit, the plane of incidence that the bottom surface of described tapered pit is collector lens, the end face of described cup type body arranges a depression, the exit facet that the bottom surface in this cave is collector lens, and the top edge of described cup type body arranges outer toroid.
The bottom surface projection of the relatively described cup of described plane of incidence type body.Described outer toroid stretches out along the end face of described cup type body, and the edge bending of described outer toroid is also pointed to plane, place, bottom surface.The edge of described outer toroid arranges directed boss, and the edge of described outer toroid arranges the seal groove of a week, and the sealing groove is positioned at the below of directed boss.The edge of described outer toroid also comprises the installation stationary plane, and described installation stationary plane slopes inwardly.The end face junction of described outer toroid and described cup type body arranges bulge loop.
The beneficial effects of the utility model are: (1) light carries out optically focused one time on convex surface, makes the projection shape of hot spot rounded, and the dispersion angle of light in lens be 20 degree, the light cover.(2) the cellular small embossment arranged on the plane of incidence, improve the uniformity of light, makes dot projection even; (3) light source adopts LED chip, and energy consumption is low, volume is little, long service life, maintenance cost are low.(4) make single little lens, can combine installation by a plurality of, make Design of Luminaires advantages of simple more.(5) positioning boss energy fixed lens, the perspective of seal groove energy fixed lens plays the effect of protection LED chip, and arranging of bulge loop can beautify lens.
The accompanying drawing explanation
Fig. 1 is the utility model top view;
Fig. 2 is A-A face figure of the present utility model.
In figure 1, cup type body; 2, tapered pit; 3, depression; 4, outer toroid; 5, stationary plane is installed; 6, seal groove; 7, directed boss; 8, bulge loop.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described:
As depicted in figs. 1 and 2, the cup-shaped collector lens of a kind of LED conical surface, comprise a glass type body 1, one end of described cup type body 1 is that the end face other end is bottom surface, described bottom surface arranges a tapered pit 2, the plane of incidence that the bottom surface of described tapered pit 2 is collector lens, and the end face of described cup type body 1 arranges a depression 3, the exit facet that the bottom surface in this cave is collector lens, the top edge of described cup type body 1 arranges outer toroid 4.
The bottom surface projection of the relatively described cup of described plane of incidence type body 1.Described outer toroid 4 stretches out along the end face of described cup type body 1, and the edge bending of described outer toroid 4 is also pointed to plane, place, bottom surface.The edge of described outer toroid 4 arranges directed boss 7, and the edge of described outer toroid 4 arranges the seal groove 6 of a week, and sealing groove 6 is positioned at the below of directed boss 7.The edge of described outer toroid 4 also comprises installs stationary plane 5, and described installation stationary plane 5 slopes inwardly.Described outer toroid 4 arranges bulge loop 8 with the end face junction of described cup type body 1.
