Description
Technical field
The present invention relates to a kind of LED light, are a kind of indicator lights for preventing light night from dazzling the eyes particularly.
Background technology
LED is referred to as forth generation lighting source or green light source, has the characteristics that energy-saving and environmental protection, long lifespan, small,
It is widely used in the fields such as various instructions, display, decoration, backlight, general lighting and urban landscape；With science and technology into
Step, the too busy to get away various electrical equipments of daily life；In places such as present family, offices, big and small electric appliance
Various indicator lights are flickered, the light of these indicator lights is covered by daylight when daytime is bright and clear, and when the evening draws on or room
The light of various indicator lights just seems very dazzling when interior dark；The indicator light especially made by LED, due to LED light
With higher directionality, and translucency is stronger, therefore the light dazzle the eyes is sent out at night, influences the ortho of people；
Especially at dead of night, the indicator light dazzle the eyes is easy to flow down ghost in eye, and not only influencing falling asleep once again for people can also be different
The deteriorated vision of degree.
Invention content
In view of the above-mentioned problems, the present invention provides a kind of glare prevention LED indicator light, which can be according to extraneous luminous intensity
Light emission luminance is automatically adjusted, soft low-light can be generated at night, can playing indicative function, not interfere with people again normal
Rest.
To solve the above problems, the technical solution adopted in the present invention is：This glare prevention LED indicator light include lampshade,
Lamp holder and chip；The chip is fixedly mounted on the lamp holder；The lampshade is double-layer structure, the hollow sandwich of the lampshade
In sealing state；Opacifier is filled in the hollow sandwich of the lampshade, the opacifier is made by glue is noncrystal；Institute
It states and is also equipped with heater strip in hollow sandwich, the heater strip is connected in parallel in the circuit of indicator light；It is concatenated on the heater strip
There is photosensitive, the photosensitive turning circuit when light is strong, the photosensitive photosurface deviates from the chip.
The beneficial effects of the invention are as follows：This glare prevention LED indicator light is mounted on to the surface of shell of machine；In daytime room
More bright, light is radiated at the photosensitive on piece, and photosensitive turning circuit is so that heating wire works, with the liter of heater strip
Temperature, the heated heating of opacifier in hollow sandwich；It is gluey noncrystal due to no fixed fusing point, it is gradually risen in temperature
When be gradually melted into transparent liquid, thereby indicate that the light of lamp can largely through and irradiate come；Therefore on daytime
Indicator light also can normally be shown when brighter；At night, indoor light is weaker, and family can close headlamp rest, at this time institute
It states photosensitive and is illuminated by the light weaker, disconnecting circuit, heater strip is stopped, and the opacifier gradually cools down, solidifies, in the mistake of cooling
Opacifier is gradually muddy in journey, and light transmittance is gradually lowered；Therefore the opacifier that the light that chip is sent out is solidified is blocked, is dissipated
Heat, the light appeared also become that soft, brightness is weaker, and brightness at this time can indicate the operating status of machine, while again will not mistake
In the dazzling normal rest for influencing resident.
Structure of the invention is exquisite, by the temperature of change opacifier to realize the adjusting of light transmittance, so that chip
Different lights can be generated at daytime, night, and the normal rest of people has been effectively ensured.
Preferably, the opacifier is paraffin；Paraffin is increasingly becoming liquid with the raising of temperature, transparency also by
It is cumulative strong, therefore liquid paraffin transparent during the day can ensure that indicator light has enough brightness；When the evening draws on, liquid
The gradual cooling solidification of state paraffin, while light transmittance weakens, entirety becomes cloudy, the light that indicator light is dazzle the eyes at this time is blocked, radiates,
Thereby indicate that lamp can only send out faint soft light, indicative function can either be played and do not interfere with sleep again.
Preferably, being close to the lampshade is equipped with two pieces of fever tablets, the heating power of two fever tablets is different；With
Convenient for forming temperature difference in hollow sandwich, and then promote the convection current of liquid paraffin.
Description of the drawings
Fig. 1 is the cross section structure schematic diagram of this glare prevention LED indicator light one embodiment.
Specific implementation mode
Embodiment
In the embodiment shown in fig. 1, this glare prevention LED indicator light includes lampshade 1, lamp holder 2 and chip 3；The core
Piece 3 is fixedly mounted on the lamp holder 2；It is close to the lampshade 1 and two pieces of fever tablets 4, the fever of two fever tablets 4 is installed
Power is different；The fever tablet 4 is electrically connected in circuit；The lampshade 1 is double-layer structure, the hollow sandwich of the lampshade 1
In sealing state；Opacifier 5 is filled in the hollow sandwich of the lampshade 1, the opacifier 5 is made by glue is noncrystal,
In the present embodiment, the glue is noncrystal is made of paraffin；Heater strip 6 is also equipped in the hollow sandwich, it is described to add
Heated filament 6 is connected in parallel in the circuit of indicator light；Photosensitive 61 is serially connected on the heater strip 6, when light is strong photosensitive 61
Turning circuit, photosensitive 61 photosurface deviate from the chip 3.
The beneficial effects of the invention are as follows：This glare prevention LED indicator light is mounted on to the surface of shell of machine；In daytime room
More bright, light is radiated on described photosensitive 61, and photosensitive 61 turning circuits are so that heater strip 6 works, with heating
The heating of silk 6, the heated heating of opacifier 5 in hollow sandwich；Paraffin is gradually risen due to no fixed fusing point in temperature
Transparent liquid is gradually melted into when high, thereby indicate that the light of lamp can largely through and irradiate come；Therefore white
Indicator light also can normally be shown when it is brighter；At night, indoor light is weaker, and family can close headlamp rest, at this time
Described photosensitive 61 is illuminated by the light weaker, disconnecting circuit, and heater strip 6 is stopped, and the paraffin gradually cools down, solidifies, and is cooling down
During paraffin it is gradually muddy, light transmittance is gradually lowered；Therefore the paraffin that the light that chip 3 is sent out is solidified is blocked, is dissipated
Heat, the light appeared also become that soft, brightness is weaker, and brightness at this time can indicate the operating status of machine, while again will not mistake
In the dazzling normal rest for influencing resident.
In the present embodiment, due to the heating power of the fever tablet 4 difference, during the day the paraffin of liquid due to
Uneven heating will generate thermal convection current, therefore the liquid paraffin in lampshade 1 will be in flow regime, the stone to ensure that etc. in covers
Wax fluid balance, fusion, stabilization, and then extend the service life of lampshade 1.
Structure of the invention is exquisite, by the temperature of change paraffin to realize the adjusting of light transmittance, so that LED light energy
It is enough that different lights is generated at daytime, night, the normal rest of people has been effectively ensured.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
