Abstract
The utility model discloses an LED (light-emitting diode) streetlamp lens, which comprises a main light-transmitting plate and a light-focusing sidewall, wherein one side of the main light-transmitting plate is connected with the light-focusing sidewall, the inner side of the light-focusing sidewall is a concave spherical panel, the outer side of the light-focusing sidewall is a cylindrical panel, the top of the concave spherical panel is in contact with the main light-transmitting plate and is formed into an inner round socket, the cylindrical panel is in contact with the main light-transmitting plate, and the top of the light-focusing sidewall is connected with a cylindrical extended plate. The light-focusing effect of the lens is good, so that the brightness of emitted light is high.
Description
Technical field
The utility model relates to field of illuminating lamps, especially a kind of LED street lamp lens.
Background technology
In recent years, light emitting diode (LED) meets the theory of energy-conserving and environment-protective because it has the advantage that power is low, brightness is high, uses more and more extensive in road, lighting of home field.Existing LED light fixture generally is comprised of aluminium base, LED, logical optical lens.Lens have important effect to illumination effect.Lens commonly used are generally the plane light-transmission plate now, to the weak effect of gathering of light, so that luminosity is low.
The utility model content
The purpose of this utility model provides a kind of LED street lamp lens, and gathering of this lens on light is effective, so that luminosity is high.
For achieving the above object, the utility model is taked following technical scheme:
A kind of LED street lamp lens, comprise principal light transmission plate and optically focused sidewall, principal light transmission plate one side links to each other with the optically focused sidewall, the optically focused inside sidewalls is the concave spherical surface plate, the outside is the cylinder panel, concave spherical surface plate top contacts with the principal light transmission plate and forms interior circular groove, and the cylinder panel contacts with the principal light transmission plate, and optically focused sidewall top is connected with the cylinder extension plate.
The both sides that described principal light transmission plate is relative are arc, and relative both sides are linear in addition.
The utility model beneficial effect is that the optically focused sidewall with concave spherical surface plate has the effect of gathering light source, so that the LED illumination effect is better.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model top view.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Shown in Figure 2 such as Fig. 1, principal light transmission plate 3 and 7 one-body molded connections of optically focused sidewall, optically focused sidewall 7 inboards are concave spherical surface plate 5, are the concave spherical surface shape, are connected with principal light transmission plate 3 at the top of concave spherical surface and are recessed to form an interior circular groove 1 downwards.The outside of optically focused sidewall 7 is cylinder panel 6, and cylinder panel 6 contacts with principal light transmission plate 3.Cylinder extension plate 2 is connected with optically focused sidewall 7.
