Description

Technical Field

[0001] This patent relates to the field of lighting technology, specifically an intelligent light-sensitive automatic-turn-on work light. Background Art

[0002] Smart photosensitive lamp technology uses photoresistors to energize the lamp circuit, thereby achieving the purpose of automatic opening and closing. The principle is that when external light shines on the photosensitive element, that is, when the light on the photoresistor is strong, the resistance value becomes low, the back-end circuit does not work, and the lamp is powered off. On the contrary, when the external light shines on the photosensitive element, the resistance of the photoreceptor becomes high, the back-end circuit works, and the lamp is powered on, thereby achieving the purpose of automatic switching.

[0003] The work lights used in existing construction sites are generally set up outdoors. At night, the work lights are used to illuminate the construction sites. However, due to the large amount of dust in the construction sites, the surface of the work lights is easily contaminated, which can easily cause a layer of dust to adhere to the surface of the photosensitive element, affecting the sensitivity of the photosensitive element.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0023] See also Figure 1-4 This patent provides a technical solution: an intelligent light-sensitive automatic working light, comprising a lamp holder 1 and a working light body 2, a lamp mounting frame 3 is mounted on the upper wall of the lamp holder 1, and the working light body 2 is mounted on the upper wall of the lamp mounting frame 3;

[0024] A photosensitive element 4 is installed on the upper wall of the working lighting lamp body 2, and a shielding mechanism 5 is installed on the upper wall of the working lighting lamp body 2, and the shielding mechanism 5 can shield the photosensitive element 4;

[0025] The light sensing element 4 proposed in this article is a photoresistor; the working lighting lamp body 2 and the light sensing element 4 are both connected to the external circuit. The specific connection method can be found in the attached Figure 5 ;

[0026] By providing the shielding mechanism 5, it is possible to prevent the photosensitive element 4 from being exposed to the outside, causing it to be contaminated by dust and affecting the sensitivity of the photosensitive element 4 itself;

[0027] The shielding mechanism 5 includes a glass cover 51, a rotating rod 52, a windshield 53, a support plate 54 and bristles 55. The glass cover 51 is installed on the upper wall of the working lighting lamp body 2. The glass cover 51 is connected to the outside of the photosensitive element 4. The upper wall of the working lighting lamp body 2 is installed with a rotating rod 52, the upper wall of the rotating rod 52 is installed with a windshield 53, the side wall of the rotating rod 52 is installed with a support plate 54, and the lower wall of the support plate 54 is installed with bristles 55. The bristles 55 can fit the side wall of the glass cover 51.

[0028] The rotating rod 52 proposed in this article can drive the support plate 54 to rotate under the blowing of wind, and then clean the upper surface of the glass cover shell 51 through the bristles 55, so as to ensure the light transmittance of the glass cover shell 51 and avoid the working lamp body 2 being contaminated by the glass cover shell 51, so that the photosensitive element 4 cannot sense the light source, causing the working lamp body 2 to light up and waste electricity.

[0029] Specifically, the rotating rod 52 includes a fixed rod 521, a bearing 522, a sleeve 523 and a dust shielding ring 524. The fixed rod 521 is installed on the upper wall of the working lighting lamp body 2. The upper wall of the fixed rod 521 is sleeved with the bearing 522. The sleeve 523 is sleeved on the outside of the bearing 522. The outside of the fixed rod 521 is sleeved with the dust shielding ring 524. The dust shielding ring 524 can be inserted and installed in the sleeve 523. The wind shielding plate 53 and the support plate 54 are both installed on the side wall of the sleeve 523.

[0030] The bearing 522 provided herein is arranged in the sleeve 523 to prevent dust from entering the bearing 522 due to heavy dust in the construction site, causing the bearing 522 to be stuck in rotation, thereby affecting the cleaning of the glass cover 51 by the bristles 55 .

[0031] Specifically, the lamp mounting frame 3 includes a telescopic rod 31 and a cross bar 32. One end of the telescopic rod 31 is mounted on the upper wall of the lamp holder 1. The other end of the telescopic rod 31 is rotatably mounted with the cross bar 32. A fixing ring 6 is mounted on the upper wall of the telescopic rod 31. A sliding groove 7 is provided on the upper side wall of the telescopic rod 31. A sliding sleeve 8 is slidably mounted in the sliding groove 7. A spring 9 is sleeved on the outer side of the telescopic rod 31. The spring 9 is arranged between the sliding sleeve 8 and the fixing ring 6.

[0032] Through the action of the spring 9, an upward thrust can be applied to the sliding sleeve 8, so that it fits with the lower wall of the cross bar 32, so that the protrusion 11 can be inserted into the positioning hole 10 below the cross bar 32, thereby completing the fixation of the angle of the cross bar 32. When adjustment is needed, the sliding sleeve 8 only needs to be slid downward to disengage the protrusion 11 from the positioning hole 10 to adjust the angle of the cross bar 32.

[0033] Specifically, a positioning hole 10 is formed on the lower wall of the crossbar 32 , and a protrusion 11 is installed on the upper wall of the sliding sleeve 8 , and the protrusion 11 can be inserted into the positioning hole 10 .

[0034] Specifically, a pin 12 is inserted into the upper wall of the lamp holder 1, and the pin 12 can be inserted and installed in the external ground;

[0035] The position of the lamp holder 1 can be fixed by the pins 12 to prevent the device from being blown down by external wind.

[0036] Specifically, the wind shield plate 53 includes a plate body 531 and an arc-shaped plate 532 . One end of the plate body 531 is mounted on the side wall of the rotating rod 52 , and the other end of the plate body 531 is mounted with the arc-shaped plate 532 .

[0037] Working principle: During use, during the day, the photosensitive element 4 is irradiated by sunlight, the resistance of the photosensitive element 4 decreases, and the main body 2 of the working lighting lamp is in a power-off state. When it is dark, the resistance of the photosensitive element 4 increases, and the main body 2 of the working lighting lamp is powered on and lights up to provide lighting for the construction site.

[0038] When the wind blows, the rotating rod 52 rotates under the action of the wind shield 53, so that it drives the support plate 54 to rotate, and then the upper surface of the glass cover shell 51 is cleaned by the bristles 55, so as to ensure the light transmittance of the glass cover shell 51, and avoid the working lamp body 2 being contaminated by the glass cover shell 51, and the photosensitive element 4 cannot sense the light source, causing the working lamp body 2 to light up and waste electricity.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
