The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See shown in Fig. 1,2 that the LED light distribution device comprises protecgulum 1, several optical lenses 2, offer lens opening 3 on the protecgulum 1 with the optical lens equal number, all be embedded an optical lens 2 in each lens opening 3, protecgulum 1 is the arc-shaped surface lid, and several optical lenses 2 are curved array and distribute.
A led chip is over against an optical lens 2, the led chip electrified light emitting, light enters in the optical lens 2 from the incidence surface 21 of optical lens 2, and refraction and reflection take place in optical lens 2, and final light transmits optical lens 2 along the exiting surface 22 of optical lens 2.
The quantity of optical lens 2 and led chip can be set according to the illumination needs, and a LED street lamp is generally installed 5～250.Even single or several led chips break down, do not influence the illumination of whole street lamp, can not cause illumination to interrupt, do not influence the safety traffic at night, therefore do not need to safeguard at any time, only need some cycles to safeguard, the led chip that replacing is broken down, maintenance cost is low.
See shown in the accompanying drawing 3 that each described optical lens 2 is solid bowl-shape lens, the less end of its diameter is an incidence surface 21, and the end that diameter is bigger is an exiting surface 22.Optical lens 2 tops cooperate with described lens opening 3, and optical lens 2 radially extended limited step 25 near top ends, and limited step 25 is tight against the medial surface of described protecgulum 1, thereby optical lens 2 and protecgulum 1 are closely cooperated, and reaches sealing effectiveness.
See shown in the accompanying drawing 4 that incidence surface 21 1 ends of the described optical lens 2 of present embodiment are concaved with light inlet groove 23 along axis direction, light inlet groove 23 is over against led chip.Wherein, the bottom land of described light inlet groove 23 is protruding arcwall face to led chip, and the cell wall of described light inlet groove 23 makes light can fully enter optical lens 2, has reduced light because of the light loss consumption that scattering causes, and has improved light utilization.
The exiting surface 22 of each described optical lens 2 is provided with a plurality of beam split salient points 24.Like this, the light that transmits from described exiting surface 22 is through the refraction of described beam split salient point 24 and to all directions uniformly dispersing, thereby makes the light intensity in the light area more even; The light that led chip sent is eliminated the spot light effect of led chip, and has been strengthened the integral illumination effect of the utility model as area source after corresponding with it optical lens 2 is handled.
See shown in the accompanying drawing 2 that present embodiment also further comprises the middle cover 4 identical with protecgulum 1 structure, protecgulum 1 is overlapping with middle cover 4, makes optical lens 2 more stably be embedded wherein good positioning effect.
The difference of present embodiment and embodiment 1 is: see shown in Fig. 5,6, the protecgulum 1 of present embodiment is a broken line shape curved surface lid, protecgulum 1 is made of 3～9 cover plates 11, adjacent cover plate 11 to become the exterior angle be 10 °～65 °, offer lens opening 3 on the cover plate 11, optical lens 2 is embedded in the lens opening 3.
By the quantity of adjustment cover plate 11 and the angle at exterior angle, optical lens 2 is reflected and reflection ray from different perspectives, the irradiation area that is installed on the led chip of optical lens 2 can carry out subregion according to different cover plate 11, by like this, each led chip forms the hot spot that some even brightness present array arrangement on shadow surface, there are not the illumination dead angle in the edge light brightness of street lamp and middle brightness uniformity, illumination range is bigger, and brightness of illumination is more even.
The above embodiment, it is better embodiment of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should comprise in the utility model patent claim.
