In prior art, the light distribution effect of the secondary light-distribution lens of LED light fixture neither be very desirable, causes the LED light source sent through secondary light-distribution lens luminous intensity distribution still to there is the uneven technical problem of light dazzle, distribution of light.
Publication number is that the Chinese patent application of CN101943368A discloses a kind of LED collector lens, described lens are truncated cone-shaped lens, lens rear face has columniform first refractive groove, its front end face has columniform second refracted slot, lens lateral wall is fully reflecting surface, the cell wall of first refractive groove and the second refracted slot forms plane of refraction, which provide little, the high optically focused of a kind of beam divergence angle, LED collector lens that light efficiency is high, solve the defect that non-round spot that in prior art, LED is formed, hot spot are uneven.But the limitation of secondary optical lens versatility, light dazzle, the uneven technical problem of distribution of light still exist.
Thus, be necessary to provide the one of improvement high-power light distributing system, to overcome the confinement problems of light-distribution lens versatility in prior art and LED light source there is dazzle and the uneven topic of Light distribation.
Utility model content
The purpose of this utility model is the shortcoming existed to overcome prior art, and provide a kind of structure simple, easy to assembly, production cost is low, and universal performance is good, a kind of LED light engine with light distributing system that light distribution effect distribution of light is even, soft.
The utility model object realizes with the following methods: a kind of LED light engine with light distributing system, it comprises radiator, reflector, eyeglass and protecgulum, it is characterized in that: described radiator front end offers the installing zone caved inward, LED light source is fixed on a heat sink by gland by the center of installing zone, the lower port of described reflector is docked with gland, wherein LED light source surface is also coated with lens, lens cross section is up-small and down-big cone-shaped, its outer inclined-plane is provided with the step that some grades of ecto-entads are upwards soaring gradually, step is provided with the reflective groove caved inward.
Described LED light source is COB area light source.
Described lens lower end is by some upright supports on retainer ring, and described retainer ring is clamped between reflector and gland.
Described column is provided with 3 uniform arrays and is distributed between lens and retainer ring.
Described lens is made by clear glass or acrylic material.
The internal groove side wall of the reflective groove on described lens and bottom land are plane, and external groove sidevall is indent arc-shaped.
Distance between described lens and COB area light source is 10-15cm.
Described reflective groove is concentric groove.
The beneficial effects of the utility model are: 1) structure is simple, and easy to assembly, production cost is low, improve the market competitiveness.2) lens cover light source surface by support, and do not have concrete connection between light source, and therefore it has good versatility, save die sinking expense, reduce production cost.3) by after the luminous intensity distribution of lens, the soft even free from glare of light that this light fixture is launched, meanwhile, lens increases the light-emitting area of light source, makes the range of exposures of this light fixture broader.

Detailed description of the invention
Below in conjunction with accompanying drawing, concrete further instruction is done to the utility model.A kind of LED light engine with light distributing system, it comprises radiator 1, reflector 2, eyeglass 3 and protecgulum 4, it is characterized in that: described radiator 1 front end offers the installing zone 11 caved inward, LED light source 6 is fixed on radiator 1 by gland 5 by the center of installing zone 11, the lower port of described reflector 2 is docked with gland 5, wherein LED light source 6 surface is also coated with lens 7, lens 7 cross section is up-small and down-big cone-shaped, its outer inclined-plane is provided with the step 9 that some grades of ecto-entads are upwards soaring gradually, step is provided with the reflective groove 91 caved inward.
Described LED light source 6 is COB area light source.
Described lens 7 lower end is supported on retainer ring 8 by some columns 81, and described retainer ring 8 is clamped between reflector 2 and gland 5.
