Abstract
The utility model discloses a lens including a pedestal and a curved surface. A flute is arranged between the pedestal and the curved surface. The curved surface is composed of a hemishere face and an anomalous curved surface. The utility model with simple structure has low cost, good effect on the second photoprocess especially adapting for a light-emitting diode lamp fitting, also widely for other types of lamp fittings.
Description
Technical field
The utility model relates to a kind of lens, is meant a kind of lens of the LED of being applicable to light fixture specifically.
Background technology
Traditional outdoor lamp generally adopts reflector to make secondary optics and handles, because the restriction of LED light efficiency, and make secondary optics with reflector and handle the serious defective of light loss, present stage is not suitable for adopting reflector to make secondary optics and handles, so generally handle the way that adopts lens mostly for the secondary optics of LED light fixture.
The existing lens that are used for light fixture generally all are simple refraction at spherical surface structures, or be optically focused, or for dispersing, all not to design at led light source specially, though light distribution is had some improvement, but poor effect is made secondary optics by collector lens and is handled, and the distribution curve flux of light fixture does not meet national standard; And by present divergent lens, Luminaire efficiency is extremely low, is not suitable for handling the secondary optics of LED light fixture.
Summary of the invention
The utility model is specially at the LED light fixture, provide a kind of simple in structure, cost is low, can carry out secondary optics to the light that led light source sent handles, the curve of light distribution of LED is reached or near in the national standard to the requirement of the distribution curve flux of light fixture, simultaneously, can improve the luminous efficiency of LED, solve present light fixture because the low illuminance that causes of LED light efficiency and the defective of luminance shortage.
A kind of lens comprise base and curved surface, are provided with groove between described base and the curved surface, and described curved surface is made up of aspheric surface and irregular surface.
Described base adopts circular ring structure.
Described groove is a sphere.
The utility model adopts lens to make secondary optics merely and handles, lens adopt groove and curved surface structure combining, each LED goes up equal correspondence one lens is set, the light that LED is sent at first carries out unirefringence by the groove of its corresponding lens, carry out birefringence by curved surface again, the curve of light distribution that can make single LEDs near or reach distribution curve flux requirement in the national Tunnel Lamp standard, the combination of several LED and lens further is set, the mean value of illuminance of ground, brightness and lamp distribution curve are up to state standards.
The utility model is simple in structure, and cost of manufacture is low, and the secondary optics treatment effect is good, is particularly useful for the LED light fixture, also can be widely used in other all kinds of light fixtures.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a bottom surface of the present utility model structural representation.
The specific embodiment
As shown in Figure 1, 2, a kind of lens comprise base 1 and curved surface, are provided with spherical groove 2 between base 1 and the curved surface, and curved surface is made up of aspheric surface 3 and irregular surface 4,
During installation, the utility model lens are installed in each LED the place ahead of LED light fixture, the light that LED sends at first carries out unirefringence by the groove 2 of its corresponding lens, carry out birefringence by curved surface again, the curve of light distribution that makes single LEDs near or reach distribution curve flux requirement in the national Tunnel Lamp standard.Adopt several by the combination that the corresponding lens of a LED form, brightness, illumination and the distribution curve flux of light fixture all can be up to state standards.
Claims (3)
1. lens comprise base (1) and curved surface, it is characterized in that: be provided with groove (2) between described base (1) and the curved surface, described curved surface is made up of aspheric surface (3) and irregular surface (4).
