Abstract

The invention provides a solar LED street lamp light-condensing lamp base. The LED lamp base is that 1W white-light LEDs and 1W yellow-light LEDs are integrated on a printed circuit board and are arranged at intervals to form a lattice plane light-emitting source, and a light-condensing lens is arranged at the front portion of the LED lamp base. The solar LED street lamp light-condensing lamp base utilizes a solar energy source to achieve street lamp control, utilizes a photoconductive resistor to achieve photoelectric control and is high in luminous efficiency, large in irradiation area and even in irradiation.

Description

Solar LED street lamp prefocus cap

Technical field

The present invention relates to illuminating street lamp field, relate in particular to a kind of solar LED street lamp prefocus cap.

Background technology

Street lamp is the important component part of city illumination, most of high-pressure mercury lamp or LED lamp of adopting now, LED lamp has more and more replaced more original other light fixture forms, but the energy waste in use of LED lamp is larger, World Environment goes from bad to worse, each state is all at development clean energy resource, and therefore, energy-conservation urgent need will overcome.

Summary of the invention

In order to solve existing technical problem in background technology, the present invention proposes a kind of solar LED street lamp prefocus cap, light extraction efficiency is high, and irradiated area is large.

Technical solution of the present invention is:

Solar LED street lamp prefocus cap, its special character is: described LED lamp holder is that 1W white light LEDs and 1W yellow light LED are integrated on printed circuit board (PCB) and are arranged as the lattice plane light emitting source of certain spacing, and the front portion of described LED lamp holder arranges collector lens.

Solar LED street lamp prefocus cap of the present invention, utilizes solar energy to realize the use of controlling street lamp, utilizes photo resistance to realize photo-electric control, prefocus cap, and light extraction efficiency is high, and irradiated area is large, irradiates evenly.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

The specific embodiment

Referring to Fig. 1, solar LED street lamp prefocus cap, comprise solar module 1, LED lamp holder 2, control cabinet 3 and lamp stand 4, solar module 1, LED lamp holder 2 and control cabinet 3 are arranged on lamp stand 4, and solar module 1, LED lamp holder 2, control cabinet 3 connect successively; Control cabinet 3 comprises controller and battery, and controller is CPU microprocessor and high-precision A/D analog-digital converter, and battery is lead-acid accumulator.

Solar LED street lamp prefocus cap 2 is that 1W white light LEDs 71 and 1W yellow light LED 72 are integrated on printed circuit board (PCB) 6 and are arranged as the lattice plane light emitting source of certain spacing; The front portion of LED lamp holder 2 arranges collector lens 5.Solar module 1 is 70W monocrystaline silicon solar cell assembly.

This circuit adopts plumbic acid maintenance-free battery, does not need special maintenance; Also can not overflow even if topple over electrolyte, in air, not discharge hydrogen and acid mist; Security performance is better.But more responsive to overcharging of battery, therefore require high to over-charge protective; After repeatedly overcharging for a long time, accumulator plate is yielding.

Controller for solar adopts high-speed CPU microprocessor and high-precision A/D analog-digital converter, is a microcomputer data acquisition and monitor control system.Both the current duty of Real-time Collection photovoltaic system fast, obtain at any time the job information at PV station, can accumulate in detail again the historical data at PV station, provide accurately foundation fully for assessing the reasonability of PV system and the reliability of checking system part quality.In addition, controller for solar also has serial communication data transfer function, multiple photovoltaic systems substation can be managed concentratedly and far distance controlled.

Solar street light is substantially the same with common streetlight control circuit function, is all in order to complete bright light in evening, and the effect that turn off the light morning, is exactly the Charge Management to battery in addition.Both at home and abroad conventional controller have independent photocontrol type, time clock type etc., but due to its operation principle difference, respectively have pluses and minuses.

Independent light-operated generally adopts sensitive probe, when that night, glazed thread was weak, automatically opens street lamp; When early glazed thread is stronger, automatically close street lamp, reach the effect of automatic control.For saving electric power, early stage light-operated switch, uses discrete-semiconductor device, circuit complexity, and components and parts are more, and volume is also larger, and fault rate is high.Along with the development of semiconductor technology, there is time-base integrated circuit.Light-controlled switching circuit is simplified.Sensitive probe is the key components that affects light-operated switch performance, its installation site also be there are certain requirements simultaneously, makes every effort to avoid various interference light, but in actual use, sensitive probe is difficult to judge various interference light, often can produce misoperation.

The controller for road lamp of clock type when employing, preset switch time, makes street lamp bright light, light-off on time on time, thereby reaches the object of automatic control.Advantage is that time switch is not subject to external interference predefined switch time, can not produce misoperation except fault own.Shortcoming is can not be according to seasonal variations and special weather condition auto-changing switch time, needs the artificial switch time of often adjusting, and wastes time and energy, and is unfavorable for saving electric power.Time switch is divided into again mechanical clock phenotype and electronic clock phenotype, and mechanical clock phenotype is take quartz clock as main, accurate while walking, but owing to using plastic gear at high temperature can be out of shape in movement, thereby cause shutting down phenomenon.

Claims

1. solar LED street lamp prefocus cap, is characterized in that: described LED lamp holder is that 1W white light LEDs and 1W yellow light LED are integrated on printed circuit board (PCB) and are arranged as the lattice plane light emitting source of certain spacing, and the front portion of described LED lamp holder arranges collector lens.
