The characteristics of original technology:
1. use secondary optical lens or reflector, but luminous intensity distribution is floodlight basically, uniformity is not good;
2. use secondary optical lens or reflector, it is poor that luminous intensity distribution cuts photosensitiveness;
3. use secondary optical lens or reflector, hot spot is circular or square basically;
4. led light source is through the optical lens direct imaging, and it is good to cut photosensitiveness, but uniformity is bad.
Shortcoming:
1. illumination uniformity is bad;
2. to cut photosensitiveness bad for the lamp distribution curve;
3. the light fixture light spot shape is circular or square, does not consider the actual inclination angle installation of light fixture and the stack illuminating effect of a plurality of light fixtures;
4. can not reach the accurate control of LED illumination.
Summary of the invention
The purpose of the utility model is to have overcome above-mentioned shortcoming of the prior art; Provide a kind of and can produce trapezoidal hot spot at face to be illuminated; Good uniformity, it is good to cut photosensitiveness, helps the inclination angle illumination is installed; Also help the stack of the illuminating effect of a plurality of light fixtures, effectively avoid luminous energy waste, reduce dazzle, LED illuminator simple and practical, with low cost.
To achieve these goals, the trapezoidal hot spot LED illuminator that the utility model provided has following formation:
This trapezoidal hot spot LED illuminator; Comprise led light source chip, optical integration post and optical lens; Wherein said optical integration post comprises close to sources end face and distance light source end face; Main feature is, described led light source chip is the small size planar light source, and described optical integration post is that end face is trapezoidal cylindrical mirror.
