Description of the Related Art Owing to the rising awareness energy saving and carbon reduction for environment protection, automatically adjusting lighting in a particular area of a 10 household environment or a public environment according to current luminous condition and default setting has become an important pursuit in intelligent energy saving. As far as a public environment is concerned, most people there won't turn off unnecessary lighting when they leave and enormous energy waste is thus caused. Hence, lights with infrared motion sensing has been developed to 15 automatically turn on or turn off according to default setting or if the environment is attended, thereby achieving the goal of energy saving and carbon reduction. However, due to the nature of infrared light being an electromagnetic wave with low energy and long wavelength, the capability of infrared light penetrating 20 through molecules of substance is weak. As a result, the accuracy and sensitivity of infrared light upon detection is lowered for the sake of effect of air density variations arising from moisture in the air and temperature difference. Additionally, regular sensing lights emphasizes whole-peripheral spherical detection and lighting effect instead of detection and lighting directing to a 2 specific angle range. To tackle the foregoing drawbacks of the conventional sensing lights, sensing means and mounting structure of the conventional sensing lights can be further improved. An objective of the present utility model is to provide a sensing LED light 5 with wide range of side illumination including a detector with highly penetrating capability and a turnable lamp base for attaining high-precision and high-sensitivity obstruction detection and lighting in a specific direction or range. To achieve the foregoing objective, the sensing LED light with wide range 10 of side illumination has a body, a turnable base, an LED module, a control module and a microwave detector. The body has an upper end and a lower end. The turnable base is rotatably connected to and is rotatable with respect to the lower end. 15 The LED module is mounted inside the body and emits light in a forward direction of the LED light. The control module is mounted inside the body and is electrically connected to the LED module. The microwave detector is mounted inside the body, is electrically 20 connected to the control module, and detects obstruction through the side portion of the LED light. The sensing LED light has the advantages of having a microwave detector serving as a detection source and a freely rotatable turnable base, thereby achieving the objective of being high-precision and high-sensitivity in terms of 3 detection and lighting in a specific direction and range.

The LED module 30 is mounted on the open end 101 of 4 the body 10. In the present embodiment, the LED module 30 has an aluminum substrate 32 and multiple LEDs 3 1 mounted on the aluminum substrate 32 to emit light in a forward direction of the LED light. With reference to Fig. 3, the power supply module 40 is mounted inside the 5 body 10, and has a light sensor 41 and a rectifying and voltage-regulating circuit 42. The light sensor 41 is mounted inside the body 10, is adjacent to the open end 101 of the body 10, and senses light through the side portion of the LED light. The rectifying and voltage-regulating circuit 42 is electrically connected to the light sensor 41, and has an input terminal and multiple output terminals. The 10 input terminal is electrically connected to the turnable base 20, and the output terminals are electrically connected to the LED module 30, the control module 50 and the microwave detector 60. With reference to Figs. 4 and 5, the body 10 further has multiple potentiometers mounted on an inner wall of the body 10. In the present utility 15 model, the multiple potentiometers include a distance potentiometer 11, a time potentiometer 12 and a luminance potentiometer 13. Each of the distance potentiometer 11, the time potentiometer 12 and the luminance potentiometer 13 is electrically connected to the rectifying and voltage-regulating circuit 42 and the control module 50. The distance potentiometer 11 serves to control a 20 detection distance of the microwave detector 30. The time potentiometer 12 serves to control settings of a turn-off cycle and a dimming cycle of the LED module 30. A symbol and multiple index markers for the setting of the turn-off cycle are shown on the left side of the time potentiometer 12. The symbol shows a bulb changing from a fully-lit light level to a dark level. When the dial of the 5 time potentiometer 12 is pointed to any of the index markers on the left side, it represents a time configured for the LED module 30 to turn into an off state and a dark state under the settings of the distance potentiometer 11 and the luminance potentiometer 13. A symbol and multiple index markers for the setting of the 5 dimming cycle are shown on the right side of the time potentiometer 12. The symbol shows a bulb changing from a fully-lit light level to into a dimming level. When the dial of the time potentiometer 12 is pointed to any of the index markers on the right side, it represents a time configured for the LED module 30 to turn into a standby state and a 10%-lit state under the settings of the distance 10 potentiometer 11 and the luminance potentiometer 13. The luminance potentiometer 13 serves to control a threshold and sensitivity of luminance received from the light sensor 4 1. The control module 50 is electrically connected to the LED module 30. and controls the LED module 30 to turn on, turn off or dini according to a sensing 15 signal of the microwave detector 60.

In the present embodiment, the microwave detector 60 is a high-frequency Doppler (HFD) radar capable of transmitting and receiving microwave signals with relatively higher energy and shorter wavelengths. Therefore, the microwave detector 60 possesses good penetration capability and analysis capability and is 6 less likely prone to environmental factors, such as moisture and temperature, rendering reliable accuracy and sensitivity. The sensing LED light further has a heat-dissipating module 70 and a lamp cover 80. With reference to Fig. 6., the heat-dissipating module 70 is in contact 5 with a rear side of the aluminum substrate 32 of the LED module 30 that is opposite to the multiple LEDs 31 such that a heat-dissipation speed of the LED module 30 can be accelerated to prevent the LED module 30 from being overheated and damaged. The heat-dissipating module 70 has two channels 71 respectively formed on two opposite edges of a surface adjoining the LED 10 module 30. The lamp cover 80 is mounted on the body 10 and the heat-dissipating module 70 to cover the LED module 30 and the light sensor 41, and has two L-shaped ribs 81 formed thereon to correspond to and engage the two channels 71 of the heat-dissipating module 70 such that the lamp cover 80 can be fastened on the heat-dissipating module 70. 15 With reference to Fig. 7, the turnable base 20 can be mounted inside a matching lamp holder in a direction parallel to a ceiling. In contrast to the way of mounting conventional LED sensing lights, the horizontal way of mounting the sensing LED light significantly shortens the distance between the ceiling and a lower end of the light, thus making the sensing LED light ideal for applications 20 of buried type and hidden type lighting equipment and making interior design and room layout more flexible and aesthetic. As the turnable base 20 is rotatable, the microwave detector 60 can be rotated to change detection range and direction thereof. The sensing LED light can provide remote control functions, such as Bluetooth, WIFI (Wireless 7 Fidelity), IR (Infrared) and voice control, built in the body 10 to enhance control functionality and compatibility. In sum, the sensing LED light includes a microwave detector 60 as a sensing source having good penetration and analysis capability without being 5 subject to the influence from environmental factors, such as moisture, temperature and the like. Moreover, given the turnable base 20, enhanced detection with high accuracy and sensitivity in a specific direction and range ensures adequate lighting in response to environmental conditions and achieves the goal of energy saving and environmental protection. 10 Even though numerous characteristics and advantages of the present utility model have been set forth in the foregoing description, together with details of the structure and function of the utility model, the disclosure is illustrative only.
