Description
Technical field
The utility model belongs to lighting area, and in particular to a kind of PC cover.
Background technique
Existing wide-angle PC cover light transmittance is low, influences whole lamp brightness.
Utility model content
In order to solve the shortcomings of the prior art, the utility model provides a kind of by increasing reflecting piece raising light transmission
The PC of rate covers.
The high PC cover of one of the utility model light transmittance, including outer cover, reflecting piece and reflector, reflector bottom are set
Have for installing fixed boss, reflector is located at outer cover upper inside wall, and reflecting piece is located at shield base, is equipped on the outside of reflecting piece
Positioning convex platform covers on positioning convex platform corresponding position equipped with limiting slot outside, and reflecting piece middle part is equipped with light source hole, and reflecting piece is white PC
It being made, outer cover and reflector are revolving structure, and using outer cover bottom centre as origin, horizontal direction is x-axis, and vertical direction is y-axis,
Outer cover lower section inner outline meets following parameter y=0.022*x*x-21.85, and cover upper inner outline meets following ginseng
Number y=- 0.007*x*x+41.02, reflector lower wheel profile meet y=0.003*x*x+28.27, and wherein x, y unit are mm.Instead
It penetrates cover and passes through ultrasonic bonding on outer cover.It is tested by actual sample, a kind of PC of the PC that light transmittance the is high cover than comparable size
Cover light transmittance is high by 3% ~ 7%, and translucent effect is good, easy to use.Datum mark A is 1 bottom centre of outer cover.
Preferably, outer cover wall thickness is 1.2mm, 2 wall thickness 0.8mm of reflector.It is at low cost, it is easy to process.
