Description

Technical Field

[0001] The invention relates to the technical field of industrial and mining lamps, and in particular to an industrial and mining lamp with a temperature sensing function. Background Art

[0002] In existing LED mining lamps, high-power LEDs are directly mounted on aluminum heat sinks, and light is reflected onto the irradiation surface through an alumina reflector installed in front of the LED light source.

[0003] Since LED mining lamps generate a lot of heat, most of them use aluminum heat sink fins as heat sinks. This kind of heat sink has disadvantages. The heat conduction capacity of the heat sink fins is limited, and the natural heat exchange effect between the heat sink fins and the outside air is not good. Especially for high-power LED mining lamps, the fins near the LED light source are hotter and the other end is colder. Therefore, the heat dissipation efficiency of the material itself is poor and the heat dissipation effect is not ideal. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides an industrial and mining lamp with a temperature sensing function, which solves the problem that the heat dissipation efficiency of the material itself is poor and the heat dissipation effect is not ideal.

[0005] To achieve the above object, the present invention provides the following technical solution: a mining lamp with a temperature sensing function, comprising an LED lamp head and an outer cover arranged on the LED lamp head and connected to an external power supply, wherein a temperature sensor is arranged on the LED lamp head, comprising:

[0006] A heat dissipation cover is arranged between the LED lamp head and the outer cover to form an overflow foundation between the LED lamp head and the outside air;

[0007] A heat dissipation auxiliary part, which is arranged on the heat dissipation cover and used to guide the gas flow direction and distinguish the heat dissipation position;

[0008] The heat dissipation cover comprises a cover shell and an air overflow hole opened on the cover shell;

[0009] The heat dissipation auxiliary component includes an outer ring partition plate group installed on the cover shell and dividing the cover shell structure based on the position of the air overflow hole. The outer ring partition plate group is installed in a symmetrical shape to divide the guide channel.

[0010] In one of the specific embodiments, the outer cover is provided with a connecting column extending upward, and the housing is provided with an extension shaft connected with the connecting column, and the cable extends inward through the connecting column on the outer cover and is electrically connected to the LED lamp holder after passing through the extension shaft;

[0011] The outer ring partition group includes a first pair of plates and a second pair of plates, the first pair of plates and the second pair of plates are cross-arranged to form a first cross unit, a third pair of plates and a fourth pair of plates are cross-arranged to form a second cross unit on one side of the first cross unit, and the first cross unit and the second cross unit are circumferentially arranged with the center of the extension axis as the axis, and are distributed on the cover shell.

[0012] In one specific embodiment, the intersection point of the first intersection unit and the second intersection unit is located on the same circle, and the arc where the two intersection points are located is concentric with the center of the extension axis;

[0013] The first pair of plates and the fourth pair of plates are connected to form a connection angle, and the second cross plate and the third cross plate extend toward the center of the circle and form an air overflow hole with the extension shaft structure;

[0014] The first pair of plates and the fourth pair of plates, when intersecting, form an elastic heat dissipation opening together with the second cross plate and the third cross plate. The elastic heat dissipation opening has a width that decreases as it is farther away from the LED light source.

[0015] In one of the specific embodiments, the elastic heat dissipation port includes a proximal wind slot and a distal wind slot, and the width of the proximal wind slot is greater than the width of the distal wind slot to increase the air intake volume to take away the heat emitted from the LED light source.

[0016] In one specific embodiment, the proximal wind slot and the distal wind slot are divided by a guide member, and the guide member includes a dividing plate installed on the side wall of the elastic heat dissipation port for separating the space between the proximal wind slot and the distal wind slot. The dividing plate is located on one side of the distal wind slot and is provided with a three-stage contraction plate. The three-stage contraction plate is installed on the side wall of the distal wind slot in an inclined state and is slidably connected.

[0017] In one specific embodiment, the three-stage retraction plate includes a first lining plate, a second lining plate and a third lining plate connected to the partition plate. The first lining plate, the second lining plate and the third lining plate have the same structure. A rotating shaft is provided at the connection between the first lining plate and the partition plate. The rotating shaft establishes a folded or unfolded state along a sliding groove opened on the side wall of the distal wind slot.

[0018] In one specific embodiment, the first lining plate, the second lining plate and the third lining plate are all provided with air guide grooves on their bottom surfaces, and the air guide grooves gradually spread from the third lining plate to the first lining plate and the second lining plate;

[0019] The air guide groove on the first lining plate is of the same shape as that arranged on the dividing plate and is used for guiding the air to the proximal air groove and the distal air groove by the three-stage retractable plate in the folded state.

[0020] In one specific embodiment, the opening position of the air overflow hole is adapted to the position of the elastic air dissipation port and the air overflow hole.

[0021] Compared with the prior art, the present invention provides a mining lamp with a temperature sensing function, which has the following features:

[0022] Beneficial effects:

[0023] In the technical solution disclosed in the present invention, an air overflow hole is opened on the cover to form an overflow basis between the LED lamp head and the outside air. At the same time, the entire cover is divided into a number of heat dissipation units based on the heat dissipation auxiliary parts arranged on the cover. Thus, the heat dissipation effect of the entire cover is based on the accumulation of the effects of the dispersed heat dissipation units, thereby forming a simultaneous consumption of the internal heat of the entire cover. While enhancing the heat dissipation, the entire heat dissipation direction can be changed by changing the heat dissipation unit, which is convenient for dealing with the problem of overheating in a single position.

[0024] In the technical solution disclosed in the present invention, a heat dissipation auxiliary component is used to change the air flow direction of the heat dissipation, so as to enhance the heat dissipation effect at a single position. In the solution disclosed in the present invention, by setting the shape of the heat dissipation auxiliary component to a first cross unit and a second cross unit, and based on the shape setting of the first cross unit and the second cross unit, the airflow rings that can be formed on the cover are divided into three types. On the one hand, the position where the heat increases faster can be dissipated for a long time and continuously. On the other hand, after the temperature sensor detects that the temperature rises and reaches the threshold, it has the basis for adjusting the ventilation channel, thereby enhancing the heat dissipation effect on the whole cover and the inside.

[0025] In the technical solution disclosed in the present invention, the temperature rise curve far away from the LED light source is obviously slower than the temperature rise curve close to the LED light source. Therefore, by setting the width of the elastic heat dissipation port to a state where the width is lower as it is farther away from the LED light source, the heat dissipation intensity close to the LED light source can be enhanced by compensating for the width while keeping the temperature diffusion rate unchanged.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1

[0038] Since LED mining lamps generate a lot of heat, most of them use aluminum cooling fins as heat sinks. This kind of heat sink has disadvantages. The heat conduction capacity of the cooling fins is limited, and the natural heat exchange effect between the cooling fins and the outside air is not good. Especially for high-power LED mining lamps, the fins near the LED light source are hotter and the other end is colder. Therefore, the heat dissipation efficiency of the material itself is poor and the heat dissipation effect is not ideal. Therefore, in addition to relying on the material itself to dissipate heat, this solution describes a mining lamp with temperature sensing function, such as Figure 1-Figure 5 As shown:

[0039] The industrial and mining lamp comprises an LED lamp head 1 and an outer cover 2 arranged on the LED lamp head 1 and connected to an external power supply. The LED lamp head 1 is provided with a temperature sensor 3 to detect the temperature value of the LED lamp head 1 and transmit it to a controller. After the heat value reaches a threshold value, the controller drives the subsequent structure to enhance the heat dissipation intensity near the LED lamp head 1, thereby achieving the ultimate purpose of heat dissipation based on material heat dissipation and airflow exchange heat dissipation.

[0040] A mining lamp with a temperature sensing function is specifically provided with a heat dissipation cover 4 and a heat dissipation auxiliary component 5 installed on the heat dissipation cover 4, wherein the heat dissipation cover 4 is arranged between the LED lamp head 1 and the outer cover 2 to form an overflow basis for the LED lamp head 1 and the outside air, and the heat dissipation auxiliary component 5 is provided outside the heat dissipation cover 4, and forms an airflow ring by guiding the gas flow direction and the different flow directions of hot and cold air. The residual heat at the LED light source is taken away by the airflow ring, the temperature value detected by the temperature sensor 3 is reduced, and the stable use of the LED lamp head is maintained.

[0041] The heat dissipation cover 4 is a heat dissipation unit as a whole, but the heat dissipation efficiency is poor if only one heat dissipation cover 4 is used for centralized heat dissipation. In order to solve this problem, Figure 4 As shown, the heat dissipation cover 4 is configured as a cover shell 41 and an integrated structure with an air overflow hole 42 on the cover shell 41. A heat dissipation auxiliary component 5 is provided on the cover shell 41, which includes an outer ring partition group 52 installed on the cover shell 41 and dividing the cover shell 41 structure based on the position of the air overflow hole 42. The outer ring partition group 52 is installed symmetrically for dividing the guide channel. Based on the heat dissipation auxiliary component 5 provided on the cover shell 41, the entire cover shell 41 is divided into a number of heat dissipation units, thereby, the heat dissipation effect of the entire cover shell 41 is based on the accumulation of the effects of the dispersed heat dissipation units, thereby forming a simultaneous consumption of the entire internal heat of the cover shell 41, while enhancing the heat dissipation, the entire heat dissipation direction can be changed by changing the heat dissipation unit, so as to deal with the problem of overheating at a single position.

[0042] like Figure 1 As shown, the outer cover 2 is provided with a connecting column 6 extending upward, and the cover shell 41 is provided with an extension shaft 51 connected with the connecting column 6. The cable extends inward through the connecting column 6 on the outer cover 2 and is electrically connected to the LED lamp holder 1 after passing through the extension shaft 51. That is, the extension shaft 51 of the cover shell 41 is the closest position to the LED lamp holder 1. Figure 3As shown, the outer ring partition group 52 includes a first cross unit 53 and a second cross unit 54, the first pair of plates 530 and the second pair of plates 531 are cross-arranged to form the first cross unit 53, the length of the first pair of plates 530 is smaller than the second pair of plates 531, the intersection of the first pair of plates 530 and the second pair of plates 531 is located on a circle with the axis of the extension axis 51, a third pair of plates 541 and a fourth pair of plates 542 are arranged on one side of the first cross unit 53, the length of the third pair of plates 541 is greater than the length of the fourth pair of plates 542, the third pair of plates 541 and the fourth pair of plates 542 are cross-arranged to form the second cross unit 54, and the first cross unit 53 and the second cross unit 54 are circumferentially arranged with the center of the extension axis 51 as the axis and distributed on the cover shell 41. By setting the shape of the heat dissipation auxiliary component 5 to a first cross unit 53 and a second cross unit 54, and dividing the airflow rings that can be formed on the cover 41 into three types based on the shape setting of the first cross unit 53 and the second cross unit 54, on the one hand, the position where the heat increases faster can be dissipated for a long time and continuously, and on the other hand, after the temperature sensor 3 detects that the temperature rises and reaches the threshold, it has the basis for adjusting the ventilation channel, thereby enhancing the overall and internal heat dissipation effect of the cover 41.

[0043] The temperature rise curve far from the LED light source is obviously slower than the temperature rise curve close to the LED light source, so the closer the ventilation position is to the LED light source, the better the heat dissipation effect. The structure of the first cross unit 53 and the structure of the second cross unit 54 both extend in the direction of the extension axis 51. Figure 3 As shown, the first pair of plates 530 and the fourth pair of plates 542 are connected to the extension axis 51 structure, and the connection forms a connection angle, and the second cross plate and the third cross plate extend toward the center of the circle and connect with the adjacent first cross unit 53 or second cross unit 54 structure behind the annular array to form an overflow hole 55 with the extension axis 51 structure. The opening position of the air overflow hole 42 is adapted to the position of the overflow hole 55 to facilitate the overflow of hot air. The setting of the overflow hole 55 ensures that the position closest to the light source of the LED lamp head 1 is always in a ventilated state, thereby facilitating the reduction of the temperature at the light source.

[0044] Second embodiment

[0045] In order to solve the problem of requiring greater heat dissipation efficiency near the LED light source, this embodiment is based on the first embodiment. Figure 6-Figure 9As shown, by forming an elastic heat dissipation vent 56 with the second cross plate and the third cross plate when the first pair of plates 530 and the fourth pair of plates 542 intersect, the opening position of the air overflow hole 42 is adapted to the position of the elastic air dissipation vent, and, based on the extension direction of the second cross plate and the third cross plate, the elastic heat dissipation vent 56 is arranged with a width that decreases as it is farther away from the LED light source. By setting the width of the elastic heat dissipation vent 56 to a state where the width decreases as it is farther away from the LED light source, the heat dissipation intensity close to the LED light source can be enhanced by compensating for the width while keeping the temperature diffusion rate unchanged.

[0046] The elastic heat dissipation opening 56 includes a proximal air slot 561 and a distal air slot 562. Figure 7 As shown, the width of the proximal wind slot 561 is greater than the width of the distal wind slot 562 to increase the air intake to take away the heat emitted by the LED light source. The proximal wind slot 561 and the distal wind slot 562 are divided by a guide member 563, as shown in FIG. Figure 7 As shown, the guide member 563 includes a partition plate 564 installed on the side wall of the elastic heat dissipation port 56 for spacing the space between the proximal wind slot 561 and the distal wind slot 562. The partition plate 564 is a straight plate installed vertically, and a wind guide slot is provided on the structure opposite to the proximal wind slot 561 to reduce the obstruction to the air flow. The partition plate 564 is located on one side of the distal wind slot 562 and is provided with a three-stage contraction plate. The three-stage contraction plate is installed on the side wall of the distal wind slot 562 in an inclined state and is slidably connected. The three-stage contraction plate includes a first lining plate 565, a second lining plate 567 and a third lining plate 568 connected to the partition plate 564. The first lining plate 565, the second lining plate 567 and the third lining plate 568 have the same structure and are all straight plates. The bottom surfaces of the first lining plate 565, the second lining plate 567 and the third lining plate 568 are all provided with wind guide slots, as shown in FIG. Fig. 9 As shown, the air guide groove is gradually dispersed from the third lining plate 568 to the first lining plate 565 and the second lining plate 567. A rotating shaft is provided at the junction of the first lining plate 565 and the partition plate. The rotating shaft establishes a folded or unfolded state along the sliding groove opened on the side wall of the distal wind groove 562. A sliding track is installed in the sliding groove. When the temperature detected by the temperature sensor 3 does not reach the threshold, the guide member 563 is in a folded state, and the proximal wind groove 561 and the distal wind groove 562 are both in a ventilation state. When the temperature detected by the temperature sensor 3 reaches or exceeds the threshold, the free end of the sliding track is controlled to drive the end of the rotating shaft to move, so as to achieve the connection state of the first lining plate 565, the second lining plate 567 and the third lining plate 568 after unfolding, thereby shielding the distal wind groove 562, exposing the proximal wind groove 561 for ventilation, and under the guidance of the guide groove, the air is prompted to flow into the proximal wind groove 561 to achieve the heat dissipation effect.

[0047] The control method of the electrical components appearing in this article is to automatically control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
