PATENTS ACT 1990 COMPLETE SPECIFICATIONS TITLE: SOLAR POWERED LED STREET LAMP WITH AUTOMATIC LIGH CONTROL Applicant: CHAN, Sze Keun Inventor: CHAN, Sze Keun Date: 28 November 2008 2
DESCRIPTION
00 SSOLAR POWERED LED STREET LAMP WITH AUTOMATIC LIGHT CONTROL 00 TECHNICAL FIELD 00This invention relates to a solar powered LED streetlight and more particularly to an LED streetlight, which has direction board or billboard or light box, brightness and darkness auto-adjustment function and can use solar as its power source.
BACKGROUND ART Typical streetlight use electric utility distribution grid power to power the lamp bulb. There are some streetlights that utilize solar power as a power supply. Because the power consumption of generic lamp is fairly high, the solar power collected in the daytime cannot supply all energy needed at night and another power source is needed for supplement.
Moreover, the streetlight stays lit all night even when no one is present so that light is not needed,, which will thereby shorten the life of the lamp bulb. Thus the current 3 00 streetlight does not achieve a goal of 100% energy savings.
1 LEDs have the advantages of long life, high luminnace, null radiation, no high strike voltage needed for start-up and low power consumption. It is a "green" power saving technology 00 oo in comparison to conventional streetlights.
00oO In addition, present roadside directional signs and guide posts are typically made from reflective materials that function by reflecting external light, such as, for example, light from a street lamp. Moreover, electronic bulletin boards and some commercial billboards need to be set up on a separate pole or stand rack.
DISCLOSURE OF INVENTION It is, therefore, an object of the invention, to solve the present technical shortage or problems and to provide a kind of green, solar-powered streetlight, which has a billboard, direction board or other type of light box with LED lighting and which has a long lifetime. The streetlight can be used on the road and in the residential area.
4 It is another object of the invention to provide a lighting or oO 0 Slight detection sensor, which will sense the lighting
(N
a conditions, sending a signal to a central controller to Sautomatically turn streetlight on or off.
o00 It is another object of the invention to provide a human 0o body detector, such as for example an infrared motion Ssensor, which will send signal to the central controller, to adjust the light to a low brightness status when nobody is in the detection area, or to adjust the light to high brightness status when somebody is in the detection area. Because the light brightness can change, it reduces wasted power and makes good use of the solar power collected in the daytime while no supplemental power is needed. Because the life of LED will not be influenced by brightness adjustments, this overall increases the life time of lamp.
It is another object of the invention to install the direction board or billboard or light box on the lamp pole.
These objects are accomplished by a solar photovoltaic board, a light detection sensor, a lamp pole, an LED lamp, an LED direction board, billboard or light box, a base with a 0 storage battery inside, a central controller and a human abody detector, such as, for example, an infrared motion Ssensor. The solar photovoltaic board is mounted on the top end of the lamp pole, the LED direction board, billboard or o00 light box is mounted on the lamp pole or the lamp pole itself is designed to be a direction board, billboard or light box, oO Sthe storage battery and the central controller are situated in the base, the infrared motion sensor and the LED lamp are mounted on the transverse bar of the lamp pole, the direction board or billboard or light box is also mounted with a photovoltaic board and a plurality of LEDs that are arrayed so as to constitute the characters or the marks on the LED direction board, billboard or light box.
The photovoltaic board collects solar power and when the light turns on in the night, the photovoltaic board on the direction board, billboard or light box continues to collect LED light power. The solar module will charge the storage battery via diode D1 and normally closed switch K2. When the central controller detects that the storage battery is full, it will connect switch K2 and K1, cut-out the charge circuit 6 and connect load R, protecting the storage battery from an 0 Sovercharge.
(Ni oThe light detection sensor configures the brightness /darkness threshold value. When the darkness threshold o00 value is met, a signal will be sent to central controller, to 00 connect switch K3. Then the power is on, lighting LED lamp and direction board, billboard or light box with low brightness and low power light. When the brightness threshold value is met, the signal will be sent to central controller, to disconnect switch K3. Then the power of the streetlight is turned off.
The infrared motion sensor is used to detect a human body.
When somebody is in the detection area, the detector will automatically send signal to central controller, the controller will adjust the voltage and current from DC/DC converter, LED lamp and LED in the direction board, billboard or light box turns into high brightness status; when the person leaves the detection area, the lamp goes back to low brightness status. As time goes on, the capacity of the storage battery goes down, the central controller will adjust 7 the voltage and current from DC/DC converter until 0 disconnecting switch K3 and connecting load R, which will
(N
aprevent storage battery from over-discharge damage.
The LED can be replaced by LED microchip or any other o00 lighting components. The invention can use generic power 00 when removing solar module and re-allocating the light N senor on the top of lamp pole.
In one embodiment, an energy-saving LED is used as lighting source and is activated by an infrared motion sensor.
When there is nobody in the detection area, particularly late at night, the light can be adjusted to a low brightness status.
As a result, power is saved and solar power that is collected in the daytime is enough for the whole night without the need for other supplemental power. And, since a light senor is used to automatically turn the streetlight on and off, fewer human resources are needed for maintenance.
For a better understanding of the invention, the objects, characteristics and advantages of the invention, examples of various embodiments are described below and are illustrated in drawing.
