Abstract
The invention discloses a brightness-adjustable bulb, comprising a power source, an engaged switch, a wick and a photoresistor, wherein the engaged switch and the wick are connected to on two ends of the power source in series to form a light emitting loop; the engaged switch and the photoresistor are connected to two ends of the power source in series to form an adjusting loop; the light emitting loop and the adjusting loop are connected in parallel; a light stopping material is coated onto the end face, close to of one side of the wick, of the photoresistor. Through the mode, the brightness of the bulb can be automatically adjusted according to surrounding environment, so that the purpose that automatically adjusts brightness of the bulb is automatically adjusted is realized.
Description
Technical field
The present invention relates to a kind of lighting apparatus, particularly the intensity adjustable bulb of one.
Background technology
Electricity-saving lamp, be also called Electricity-saving lamp bulb, refer to and fluorescent lamp and ballast (stabilizer) be combined into an overall lighting apparatus, present stage, electricity-saving lamp is extensively subject to consumers by feat of the feature of self energy-saving facile, and improving constantly along with present living standard, electricity-saving lamp is also faced with other puzzlement, if the bulb in current electricity-saving lamp is under the condition of identical voltage, its brightness cannot change, along with the living standard of people is more and more higher, this bulb has not caught up with the demand of present people.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of intensity adjustable bulb, and the brightness that bulb automatically can be regulated to send according to the brightness of surrounding environment, achieves the object that bulb regulates luminosity automatically.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of intensity adjustable bulb, comprise: power supply, turn on-switch, wick and photo resistance, the two ends that described turn on-switch and described wick are connected on described power supply form luminous loop, the two ends that described turn on-switch and described photo resistance are connected on described power supply form regulating loop, described luminous loop and the parallel connection of described regulating loop, described photo resistance is coated with and is brushed with resistance luminescent material on a side end face of described wick.
In a preferred embodiment of the present invention, described resistance luminescent material is graphite, and the light preventing bulb self from sending affects the resistance size of photo resistance.
In a preferred embodiment of the present invention, be also in series with fixed value resistance in described luminous loop, protection bulb can not be excessive and damage due to electric current.
In a preferred embodiment of the present invention, the voltage of described power supply is 220V.
The invention has the beneficial effects as follows: the brightness that the present invention can regulate bulb to send according to the brightness of surrounding environment automatically, achieve the object that bulb regulates luminosity automatically.
Accompanying drawing explanation
Fig. 1 is the present invention's circuit theory diagrams in a preferred embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of intensity adjustable bulb, comprising: power supply U, turn on-switch S, wick L and photo resistance R
g, the two ends that described turn on-switch S and described wick L is connected on described power supply U form luminous loop, described turn on-switch S and described photo resistance R
gthe two ends being connected on described power supply U form regulating loop, described luminous loop and the parallel connection of described regulating loop, described photo resistance R
gbe coated with on a side end face of described wick and be brushed with resistance luminescent material.
Wherein, described resistance luminescent material is graphite, and because graphite has good resistance optical property, thus the light that can prevent bulb self from sending affects the resistance size of photo resistance.
Also be in series with fixed value resistance R in described luminous loop, can protect bulb can not be excessive and damage due to electric current.
The voltage of described power supply U is 220V.
Be different from prior art, present invention is disclosed a kind of intensity adjustable bulb, its specific works principle is: open turn on-switch S, and power supply U powers to luminous loop and regulating loop simultaneously, and now wick L starts luminescence, the R of photo resistance simultaneously
gthe upper side near wick L is coated with and is brushed with resistance luminescent material, makes photo resistance R
gthe light in bad border around can only be received, thus regulate self-resistance value, the electric current in luminous loop be changed automatically, finally realizes the object of the automatic adjustment of bulb brightness.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
