Description

A solar sensor light

technical field

The utility model relates to a solar induction lamp.

Background technique

At present, the induction lamps on the market are usually directly fixed by hanging, and there is no special structure for fixing, which makes the normal service life of the induction lamps may be affected by long time or external bad weather during use. In addition, the more common induction lights at present use direct current as energy to provide lighting, which does not achieve the goal of green life for the contemporary society with increasingly tense energy sources. Therefore, it is necessary to develop an induction light that uses new environmentally friendly energy sources.

Therefore, it is very important to provide an induction lamp that can be used normally under bad weather and adopt new energy to meet people's living needs.

Utility model content

The purpose of the utility model is to provide an induction lamp which can be effectively held and uses solar energy as an energy source.

In order to achieve the above object, the utility model adopts the following technical solutions: a solar induction lamp, which includes a lampshade, a probe circuit board, a cover plate, a lens, an LED lamp, a reflector, a rechargeable battery, a housing, the lens, the probe circuit The plate and the cover plate are fixed on the lampshade, and the lampshade is assembled on the casing, which further includes a solar cell fixed on the casing, and a locking mechanism is connected with the casing.

Compared with the prior art, the utility model has the following beneficial effects: the utility model ensures the double fixation of the induction lamp after installation by setting a locking mechanism on the housing of the induction lamp, and at the same time, it uses solar cells as energy supply to save energy. energy.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Fig. 1 and Fig. 2, a solar sensor lamp, which includes a lampshade 1, a lens 2, a probe circuit board 3, a transparent cover 4, an LED lamp 11, a reflector 6, a casing 7, and a rechargeable battery 10, The lens 2, the probe circuit board 3 and the cover plate 4 are fixed on the lampshade 1, and the lampshade 1 is assembled on the housing 7, which further includes a solar cell 8 fixed on the housing 7, a locking mechanism 12 and The housing 7 is connected. A rubber seal 5 is installed at the assembly place between the reflector and the housing.

The rechargeable battery 10, the LED lamp 11, the main control circuit board 14, and the foam 15 are connected to the casing through the screws on the plastic cover 16, and the solar battery 8 is connected to the casing 7 through a buckle on a fixing plate 9. connected.

The locking mechanism 12 is connected to the housing 7 through screws on the metal cover 13 ; the metal fixing frame 17 fixes the product at the installation position through the metal cover 13 .

When the sun is shining during the day, the solar panel converts the solar energy into electrical energy. The solar charging control part of the circuit uses MPPT (Maximum Power Point Tracking) technology to charge the battery with maximum efficiency until the battery voltage reaches the highest cut-off voltage. The control part of the circuit turns off MPPT and turns to trickle charging.

This product is used for induction lighting at night, and the induction part of the circuit is turned off during the day to save the limited energy of the battery, especially in continuous rainy days, there is enough power to maintain normal lighting. At night, the sensing part of the circuit works. When the product is within the sensing area and detects that the human body moves at 0.30-3 m/s, the sensing part of the circuit detects that the sensing signal is amplified internally and sent to the MCU (single-chip microcomputer) for processing. . The MCU outputs PWM (Pulse Width Modulation) to drive the LED lights.

When the battery voltage is lower than the minimum cut-off voltage of the battery, the product will automatically turn off the LED output to protect the battery from damage. At this time, the circuit is working in a sleep state, working with the lowest power consumption in the microampere level, and flashing the low-voltage alarm light once in 3 seconds to remind the product that the power is insufficient and cannot be sensed. This method can work continuously for 10 days.
