CN201412772Y - Circular light uniformization panel for LED lamp - Google Patents

Abstract

The utility model belongs to the technical field of light uniformization panels, and discloses a circular light uniformization panel for an LED lamp. The circular light uniformization panel has the main technical characteristics that a baseplate made of transparent material is included, a light uniformization strip with a saw-toothed cross section is arranged on the baseplate, the light uniformization strip is formed through arranging a plurality of light uniformization bodies, each light uniformization body is a curved surface with a thin central part and a thick periphery, and the cross section of the light uniformization body is approximately a half-bow shape. As a further improvement, the radian of the half-bow shape camber line is 40 plus or minus 6 degrees. Therefore, light rays arescattered after penetrating through the light uniformization strip and the baseplate, and uniformly irradiated, thereby solving the problems of dazzling and uneven luminance of the prior street lamp and easy occurrence of traffic accidents; and the baseplate and the light uniformization strips can be manufactured to be thinner, thereby reducing light loss, enhancing light transmittance and being convenient for the popularization of LED lamps. The circular light uniformization panel can be widely applied to the field of street lamps.

Description

The LED lamp is with the equal tabula rasa of circular light

Technical field

The utility model belongs to equal tabula rasa technical field, relates in particular to a kind of LED lamp with the equal tabula rasa of circular light.

Background technology

Raising along with energy-conservation requirement, the LED lamp replaces original incandescent lamp gradually, in the application in fields such as street lamp more and more widely, still since the LED lamp in a bar shaped brightness height then light is very dark in peripheral field, can be dazzling, dazzling in the place that brightness is high, and secretly do not see because of light in peripheral field, traffic accident takes place easily, and common lampshade light transmission is poor, light attenuation is serious, therefore is difficult to promote on a large scale.

The utility model content

The technical problems to be solved in the utility model just provide a kind of go up in a certain direction illumination evenly, do not stay lighting dead angle and do not have that dazzling high light, light transmission are good, the LED lamp of being convenient to promote the LED lamp is with the equal tabula rasa of circular light.

For addressing the above problem, the technical solution adopted in the utility model is: comprise the substrate of being made by transparent material, it is the equal striation of zigzag that described substrate is provided with the cross section, described equal striation by several all the light body arrange and to form, each all the light body be the thick curved surface of the thin periphery in center, it is half arc that its cross section is similar to.

Its additional technical feature is:

The radian of described half arc camber line is 40 ± 6 °;

The inclined-plane of described equal striation tilts to a direction;

Described equal striation is to symmetric arrays.

LED lamp provided by the utility model with the equal tabula rasa of circular light compared with prior art, have the following advantages: one, owing to comprise the substrate of making by transparent material, it is the equal striation of zigzag that described substrate is provided with the cross section, described equal striation by several all the light body arrange and to form, each all the light body be the thick curved surface of the thin periphery in center, its cross section is similar to partly arc, after light sees through equal striation and substrate, scattering takes place, the light uniform irradiation, it is dazzling to have solved present street lamp, brightness irregularities, the problem of traffic accident takes place easily, and substrate has reduced light losing with all striation can be thinner, improve light transmittance, be convenient to the popularization of LED lamp; Its two because the radian of described half arc camber line is 40 ± 6 °, make that the light irradiation is more even; Its three since the inclined-plane of described equal striation to a direction tilt or described equal striation to symmetric arrays, make illumination more even.

Description of drawings

Fig. 1 is the side sectional drawing of the utility model LED lamp with the equal tabula rasa of circular light;

Fig. 2 is the sectional drawing along the axially equal striation of equal striation.

Fig. 3 is equal sectional view of light body;

Fig. 4 is the side sectional drawing of the LED lamp of equal striation symmetric arrays with the equal tabula rasa of circular light.

The specific embodiment

Below in conjunction with accompanying drawing structure and the use principle of the utility model LED lamp with the equal tabula rasa of circular light is described in further details.

As Fig. 1, Fig. 2 and shown in Figure 3, the utility model LED lamp comprises the substrate of being made by transparent material 1 with the equal tabula rasa of circular light, it is the equal striation 2 of zigzag bar shaped that substrate 1 is provided with the cross section, all striation 2 by several all light body 3 arrange and form, each all light body 3 be the thick curved surface of the thin periphery in center, it is half arc that its cross section is similar to.Certainly, also can on substrate 1, have zigzag groove 4, form the equal striation 2 of zigzag bar shaped, on equal striation 2, dig the cross section and be similar to half arc semi-circular groove 5.After light sees through equal striation 2 and substrate 1, scattering takes place, the light uniform irradiation, solved that present street lamp is dazzling, brightness irregularities, easily the problem of traffic accident taken place, and substrate 1 and all striation 2 can be thinner, light losing reduced, improve light transmittance, be convenient to the popularization of LED lamp.

All to be similar to the radian of half arc camber line be 40 ± 6 ° in the cross section of light body 3.Like this, make the road surface various piece not stay dark dead angle.

In order to make illumination more even, all the inclined-plane 21 of striation 2 tilts to a direction, the symmetric arrays that equal striation 2 also can be as shown in Figure 4.

This LED lamp not only is applicable to the LED lamp with the equal tabula rasa of circular light, for the lampshade that uses on the other light sources, as long as structure is identical with the structure of the equal tabula rasa of circular light with above-mentioned LED lamp, all falls within the utility model protection domain.

Claims (4)

1, the LED lamp is with the equal tabula rasa of circular light, comprise the substrate of making by transparent material, it is characterized in that: it is the equal striation of zigzag that described substrate is provided with the cross section, described equal striation by several all the light body arrange and to form, each all the light body be the thick curved surface of the thin periphery in center, it is half arc that its cross section is similar to.
