Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and more particularly to an LED headlamp. Background Technology

[0002] Headlamps, as a hand-free lighting tool worn on the head, have been used in various industries, such as surveying, mining, forestry, aquaculture, agriculture, emergency rescue, and outdoor exploration. Traditional headlamps are mostly manually controlled by mechanical buttons to turn on or off. However, during use, dirt and water from fingers can easily cause buttons to malfunction, soil the headlamp, or even damage internal electronic components. Furthermore, uneven pressure when pressing the buttons can cause the headlamp to tilt or even fall, interrupting work. To address this, Chinese utility model patent CN202223439910.9 discloses a gesture-sensing headlamp that can be controlled by waving hands, offering convenient operation and truly freeing up the hands. However, this headlamp has the following problems: First, it only has one infrared transmitter and one sensor receiver. The first two hand gestures can turn on the light and increase its brightness, but the third gesture will turn it off directly. It cannot control the light brightness by waving, which is inconvenient. Second, it can only be powered by a charger, so it cannot be used in an emergency when it is not charged in time. In addition, the overall structure of the product is relatively complex, with many parts, making assembly cumbersome. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a gesture-controlled headlamp with a simpler structure, more reasonable design, and the ability to turn the light on and off, increase and decrease brightness via gestures, making it more convenient to use and providing a more reliable power supply.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a gesture-sensing controlled headlamp, including a housing, a circuit board, a reflector, a power supply mechanism, and a headband. The circuit board, reflector, and power supply mechanism are installed in the housing. The circuit board is equipped with LED beads, a transmitter for sensing gestures, and a receiver. The reflector is located in front of the circuit board. The LED beads, transmitter, and receiver extend out of the reflector. The circuit board is connected to the power supply mechanism. The receiver includes one unit, and the transmitter includes two units, namely a first transmitter and a second transmitter. The first transmitter and the second transmitter are arranged in a left-right configuration, separated by a distance. The receiver is located within the range between the two transmitters. The first transmitter and the receiver cooperate to form a control structure for controlling the light to turn on and increase in brightness. The second transmitter and the receiver cooperate to form a control structure for controlling the brightness to decrease and the light to turn off.

[0005] Furthermore, the receiver is located above the midpoint between the two transmitters, and the second transmitter is located to the left of the first transmitter. The receiver, the first transmitter, and the second transmitter form an upright isosceles triangle structure.

[0006] Furthermore, three through holes are provided in the lamp cup, and the receiver and two transmitters are respectively embedded in the three through holes.

[0007] Furthermore, the power supply mechanism includes a lithium battery and a dry cell battery. The lithium battery is installed in the housing via a battery bracket, and the dry cell battery is installed in a battery box. The battery box is installed in the housing via a battery box bracket. The lithium battery and the dry cell battery are respectively connected to a circuit board to form a dual power supply structure.

[0008] Furthermore, the housing includes a main shell and a rear cover. A transparent lens, which is integral with the main shell, is provided on the front of the main shell and is located in front of the optical cup. A fastener is provided on the main shell and a buckle is provided on the rear cover. The circuit board, optical cup and power supply mechanism are covered inside by the buckle and the fastener fastening each other.

[0009] Furthermore, an in-mold forming process is used to cover the outside of the main shell with a rubber shell, on which a switch button is provided, and the switch button is connected to a mechanical switch on the circuit board.

[0010] Preferably, the device also includes a mounting base, which is rotatably mounted at the rear of the housing, and the headband is assembled and fixed to the mounting base.

[0011] Preferably, three LED beads are arranged on the circuit board, and the three LED beads, the transmitter and the receiver are arranged at intervals to form an inverted isosceles triangle structure.

[0012] Preferably, the transmitter is an infrared transmitter and the receiver is an infrared receiver.

[0013] This invention utilizes two transmitters and one receiver, positioned separately on the left and right sides, with the receiver in the center. One transmitter works with the receiver to increase brightness, while the other works with the receiver to decrease brightness. This allows for control of light brightness by varying the direction of hand gestures, improving ease of use and freeing up the user's hands. Furthermore, by incorporating both lithium and dry cell batteries, emergency lighting can be provided using dry cell batteries when the lithium battery is low. Additionally, the reduced number of parts simplifies the product structure and makes assembly easier. Attached Figure Description

Detailed Implementation

[0019] In this embodiment, refer to Figures 1-4 The gesture-sensing headlamp includes a housing, a circuit board 3, a light reflector 4, a power supply mechanism, and a headband 12. The circuit board 3, light reflector 4, and power supply mechanism are housed within the housing. The circuit board 3 is equipped with LED beads 31, a transmitter for sensing gestures, and a receiver 34. The light reflector 4 is positioned in front of the circuit board 3, with the LED beads 31, transmitter, and receiver 34 extending from it. The circuit board 3 is connected to the power supply mechanism. There is one receiver 34 and two transmitters: a first transmitter 32 and a second transmitter 33. The first transmitter 32 and the second transmitter 33 are arranged side-by-side, separated by a gap. The receiver 34 is located between the two transmitters. The first transmitter 32 and the receiver 34 work together to control the light's on / off state and brightness increase, while the second transmitter 33 and the receiver 34 work together to control brightness decrease and light off. The transmitters are infrared transmitters, and the receiver 34 is an infrared receiver. The infrared light emitted by the transmitter is blocked by the hand to be received by the receiver 34.

[0020] The receiver 34 is located above the midpoint between the two transmitters, and the second transmitter 33 is located to the left of the first transmitter 32. The receiver 34, the first transmitter 32, and the second transmitter 33 form an upright isosceles triangle structure. When the hand is waved from right to left, the first transmitter 32 and the receiver 34 work together to sense the increase in brightness. The first wave turns on the light, the second, third, and so on, increasing the brightness. A three-level mode is generally used, but more or less than three levels are possible, such as five levels. When the hand is waved from left to right, the second transmitter 33 and the receiver 34 work together to sense the decrease in brightness. The first and second waves decrease the brightness, and so on, until the last wave turns off the light, such as the fifth wave. A three-level mode is also generally used, but more or less than three levels are possible, such as five levels. Stepless dimming can also be achieved. Of course, this technology of increasing or decreasing brightness through gesture sensing is existing technology and is used in many products, including headlamps, hair dryers, and range hoods. This invention can directly utilize existing technology, so its specific implementation principle will not be elaborated here.

[0021] The lamp cup 4 has three through holes, and the receiver 34 and two transmitters are respectively embedded in the three through holes.

[0022] The power supply system includes a lithium battery 6 and dry cell batteries (such as three AAA batteries). The lithium battery 6 is mounted in the housing via a battery bracket 5, and the dry cell batteries are housed in a battery compartment 8. The battery compartment 8 is mounted in the housing via a battery compartment bracket 7. The lithium battery 6 and the dry cell batteries are connected to a circuit board 3 to form a dual power supply structure. Normally, the lithium battery 6 provides power, but when the lithium battery 6 is low, it automatically switches to dry cell battery power.

[0023] The housing includes a main shell 2 and a rear cover 9. The main shell 2 can be made of PC material. A transparent lens, integral with the main shell 2, is provided on the front of the main shell 2 and is located in front of the optical reflector 4. A fastener 21 is provided on the main shell 2, and a buckle 91 is provided on the rear cover 9. The circuit board 3, optical reflector 4, and power supply mechanism are covered inside by the buckle 91 and the fastener 21 fastening each other. No screws are required for fixing, making assembly more convenient.

[0024] A rubber-coated shell 1 is formed and in-mold-molded over the main shell 2. A switch button 11 is mounted on the rubber-coated shell 1, which interfaces with a mechanical switch on the circuit board 3, serving as a backup manual switch. The rubber-coated shell 1 can be made of soft rubber such as TPR, and its color can be freely selected. This not only enhances the overall aesthetics of the product but also provides protection and a sealing effect, achieving a waterproof rating of IPX8.

[0025] It also includes a mounting base 10, which is rotatably mounted at the rear of the rear cover 9 so that the irradiation angle can be adjusted, for example, by 60 degrees. The headband 12 is assembled and fixed to the mounting base 10.

[0026] Three LED beads 31 are arranged on the circuit board 3. The three LED beads 31, the transmitter and the receiver 34 are arranged at intervals to form an inverted isosceles triangle structure.

[0027] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
