The optical wavelength of sending is in 380~800nm, and therefore, existing photosensitive sensor can not accurately tell ring in intelligent lighting application
It is daylight or LED lamplight in border, intelligent lighting is not accomplished only to be controlled by sunlight intensity, can not eliminate the shadow of neighbouring LED lamplight
It rings.
Summary of the invention
Object of the present invention is to: a kind of photosensitive sensor is provided, accurately distinguishes out daylight or LED lamplight, realize individually by
Daylight power controls the power of lamp luminescence, reaches all-weather intelligent energy conservation.
The technical scheme is that
Photosensitive sensor, including light-sensitive device, are covered with a shade outside the light-sensitive device, and shade filters out 380~
The light of 800nm wavelength.
Preferably, the shade is integrally formed by light-transmitting materials by molding or injection molding, and surface coats filter layer,
Or it is made of the optical filter splicing of several surfaces coating filter layer.
Preferably, the shape of the shade is one of rectangular, round, cylindrical, conical, triangular pyramid type.
Preferably, the light-sensitive device bottom is fixed on wiring board, and shade cover is buckled in right above light-sensitive device, photosensitive
Device is located at shade center.
Preferably, it is sealed between the shade and wiring board by viscose glue.
Alternatively, another scheme:
Photosensitive sensor, including light-sensitive device, light-sensitive device surface have light penetrating device, and the light penetrating device surface is coated with filter
Photosphere filters out the light of 380~800nm wavelength.
Preferably, the ingredient of the filter layer includes: mixture A, silica and the titanium oxide of silica and lithia
Mixture B.
Preferably, the mixture A and mixture B passes through 40~60 alternating coatings, forms filter layer.
The invention has the advantages that
Photosensitive sensor of the invention is covered with a shade outside light-sensitive device, and shade filters out 380~800nm wavelength
Light excludes LED and issues light, the light of 800nm above wavelength is only allowed to be received by photosensitive sensor through hood, sensor received from
The different of right illumination wavelength generate difference signal, and whether accurately told using the difference signal has daylight, Ke Yiguang in environment
The general intelligent lighting field being applied to using the control of photosensitive principle, realizes all-weather intelligent energy-saving illumination.
