Abstract

The utility model provides an LED (Light-Emitting Diode) street lamp. The LED street lamp has the beneficial effects that a lens is additionally arranged in a lamp shell, so that all parts of the street lamp more uniformly emit light; reflecting particles on the lens reflect a part of light rays, so that the illumination intensities of all the parts are distributed again, and further, all the parts more uniformly emit the light, and the light rays are softer; and moreover, the use efficiency of fluorescent powder is improved, and the brightness is better.

Description

The LED street lamp
Technical field
The utility model provides a kind of LED street lamp.
Background technology
LED is as a kind of novel solid light source; Have not only that power consumption is low, long working life, be easy to advantages such as light modulation toning, energy-conserving and environment-protective; All will surmount conventional light source such as incandescent lamp, fluorescent lamp greatly aspect its production, manufacturing, the ease for use, at present a lot of street lamps also adopt LED as light source.The instructions for use of street lamp needs the rising angle of light source big, and light is soft, but because the self-characteristic of led chip, the light that led light source sends focuses mostly in the dead ahead of chip, and the light distribution of whole exiting surface is inhomogeneous, the center light intensity, all around very a little less than.It is big that this just makes that the LED street lamp does not reach range of exposures, and brightness is high, the effect that light is soft, and the uneven weakness of bright dipping can be given the very dazzling sensation of people, but also glare phenomenon can occur.Though the manufacturer that has enlarges beam angle through lens are set, all be outside each chip, lens to be set, because chip area is very little, and the lens great majority are to adopt the silica gel coagulation forming, so to the diffusion of light and not obvious.
The utility model content
The utility model technical problem to be solved provides a kind of LED street lamp, and this LED street lamp emitting brightness is high, and the each several part bright dipping is even, and light is softer.
The technical scheme that the utility model technical solution problem is adopted is: this LED street lamp comprises lamp housing, first lens and is installed at least one led chip on the substrate; Said substrate is fixed in the lamp housing; Said first lens are provided with fluorescent material, in said lamp housing, also are provided with second lens.The light that led chip sends shines out after the diffusion of second lens, has enlarged rising angle, makes range of exposures bigger.
Said second lens are provided with light-reflecting particles, and light-reflecting particles reflexes to a part of light on first lens and the substrate.
Said light-reflecting particles is arranged at the inner surface of said second lens, has simplified production technology.
In order further to improve radiating effect, also be provided with fin in the bottom of said lamp housing.
The beneficial effect of the utility model is: this LED street lamp has been introduced light-reflecting particles in a creative way; Light-reflecting particles and substrate repeatedly reflect part light, make the bright dipping of LED street lamp each several part more even, and beam angle is bigger; There are not obvious bright dipping strong point and illumination dead angle; So the light that whole light fixture sends is softer, not dazzling, range of exposures is also bigger.And some understands excitated fluorescent powder once more in the light that is returned, and has improved the service efficiency of fluorescent material, and under the situation that does not increase led chip quantity, emitting brightness is higher, thereby has practiced thrift cost.
Description of drawings
Fig. 1 is the cutaway view of the utility model LED street lamp.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Fig. 3 is the cutaway view of the another kind of structure of the utility model LED street lamp.
Fig. 4 is the partial enlarged drawing at B place among Fig. 3.
The specific embodiment
As depicted in figs. 1 and 2; 6 pairs of light of second lens, 6, the second lens are set in lamp housing 1 has disperse function, the light that led chip 3 is sent to around disperse; Increased the beam angle of whole street lamp, second lens 6 also play certain protection and dustproof effect simultaneously.Being arranged on light-reflecting particles 7 on second lens 6 returns a part of light and is mapped on the substrate 2 and first lens 5.Diffuse effect has been played in the repeatedly reflection of light-reflecting particles 7 and 2 pairs of light of substrate, and whole light out part branch light intensity is more evenly distributed.Be reflected the light of returning some shine on first lens 5; Excitated fluorescent powder 4 once more, and the service efficiency of fluorescent material 4 improves, thereby under the situation of the doping of quantity that does not increase led chip 3 and fluorescent material 4; It is bigger to go out luminous intensity, and the brightness of irradiated area is higher.
Like Fig. 3 and shown in Figure 4, a kind of better mode is, light-reflecting particles 4 is coated in the inner surface of second lens 6, and difficulty of processing is lower, and the material of second lens 6 required lower, and the selection range of second lens 6 is more extensive.
As shown in figures 1 and 3, the bottom of lamp housing 1 is provided with fin 8, has strengthened the contact area of lamp housing 1 with air, has improved heat exchanger effectiveness, and radiating effect is better.
