Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and more specifically, to an LED spot lamp which is convenient for heat dissipation. Background Technique

[0002] LED, that is, light-emitting diode, has the advantages of rich colors, energy conservation and environmental protection, and is widely used in daily and stage lighting. When current is injected into an LED lamp, a part of the electric energy is converted into light energy to emit light, and another part of the electric energy is converted into heat energy and dissipated. When the heat accumulated in the LED lamp cannot be dissipated in time, it will cause the temperature of the semiconductor transistor to rise, resulting in uneven distribution of thermal stress, affecting the light efficiency and service life of the LED lamp.

[0003] Especially for the LED spot lamp used in stage lighting, it has a larger power, higher brightness, and faster heat generation efficiency. Therefore, in order to avoid heat accumulation in the inner cavity of the housing, in the prior art, heat dissipation fins are arranged in the inner cavity of the housing to increase the gap between the lamp and the inner cavity of the housing, so that heat can enter the gap and be transferred to the housing, and heat exchange between the lamp and the external environment is realized through the housing and the gap, avoiding all the generated heat from accumulating on the lamp, increasing the temperature of the lamp, and affecting the service life and brightness of the lamp. However, since the housing of the stage spot lamp is a closed housing, when the high-power LED stage spot lamp works, it is difficult to quickly realize heat exchange through the housing, and heat accumulation will still occur after long-term work, affecting the service life and brightness of the lamp. Content of the Utility Model

[0004] The utility model aims to overcome the problem in the prior art that the stage spot lamp with a closed housing is difficult to dissipate heat quickly, resulting in heat accumulation on the lamp, affecting the service life and brightness of the lamp, and provides an LED spot lamp which is convenient for heat dissipation. The spot lamp of this solution has heat dissipation holes communicating with the outside at both ends, which can accelerate the heat dissipation speed of the lamp and avoid the problem of heat accumulation on the lamp.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: an LED spot lamp which is convenient for heat dissipation, including a housing, an end cover and a spot lamp module. The spot lamp module includes a condenser cover. A plurality of heat dissipation ribs are arranged in the inner cavity of the housing at equal circumferential intervals with the axis of the housing as the center of the circle. The condenser cover and the end cover are respectively located at the front end and the rear end of the housing. The housing, the end cover and the condenser cover are coaxial, and the radii of the end cover and the condenser cover are both smaller than the inner cavity radius of the housing, so that heat dissipation gaps are formed at both ends of the housing. A fixing module is also arranged in the inner cavity of the housing. The fixing module is connected with the housing and is used for fixing the spot lamp module.

[0006] The groove formed between the two heat dissipation ribs in the inner cavity of the housing is the heat dissipation groove. When the spotlight is working, when the heat generated by the spotlight module dissipates outward, first, the heat will accumulate in the heat dissipation groove formed by two adjacent heat dissipation ribs. And the distribution of heat in the heat dissipation groove is that there is more heat near the spotlight module and less heat far from the spotlight module. And as the spotlight continues to work, the spotlight module continuously generates heat, causing the heat in the heat dissipation groove to transfer to both ends of the heat dissipation groove. Since the radius of the condenser cover and the radius of the end cap are both smaller than the radius of the inner cavity of the housing, heat dissipation gaps communicating with the outside are formed at both ends of the housing, and the heat in the heat dissipation groove can dissipate to the outside along the heat dissipation gaps at both ends of the housing, completing the heat exchange between the inner cavity of the housing and the outside, and achieving the purpose of spotlight heat dissipation.

[0007] In the spotlight of this solution, heat dissipation gaps communicating with the outside are provided at both ends of the housing. The heat inside the housing can dissipate to the outside along the heat dissipation grooves formed by the heat dissipation ribs, and the external air flow can also enter the inner cavity of the housing through the heat dissipation gaps, completing the energy exchange between the inside of the housing and the external environment, achieving the purpose of rapid heat dissipation of the spotlight, and avoiding heat accumulation on the lamp, which affects the life and brightness of the lamp.

[0008] Preferably, the width of the heat dissipation gap is 4 mm - 5 mm, and the height of the heat dissipation rib is greater than the width of the heat dissipation gap. It has been proved by experiments that when the width of the heat dissipation gap is between 4 mm and 5 mm, the heat dissipation effect inside the spotlight is the best, and it can also prevent other sundries from entering the inner cavity of the housing along the heat dissipation gap. The height of the heat dissipation rib is greater than the width of the heat dissipation gap, which can not only guide the heat dissipating outward from the heat dissipation groove and the air flow entering the inner cavity of the housing from the outside, but also further prevent external sundries from entering the inner cavity of the housing.

[0009] Preferably, the spotlight module further includes an LED driving part, an LED emitting part, and a control part. The control part, the LED driving part, and the LED emitting part are electrically connected in sequence. The LED emitting part is fixedly connected to the condenser cover. The fixing module includes a fixing part and a heat dissipation part. The side wall of the fixing part is provided with fixing ribs, and the fixing ribs are connected to the heat dissipation ribs. The fixing part is fixed in the inner cavity of the housing through the fixing ribs and the heat dissipation ribs. The LED emitting part is fixedly connected to the fixing part. The heat dissipation part is a metal heat dissipation block. A connecting piece is provided on the heat dissipation part. Two ends of the connecting piece are respectively connected to the heat dissipation part and the heat dissipation ribs. The heat dissipation part is connected to the housing through the connecting piece. The bottom surface of the heat dissipation part abuts against the LED driving part. An accommodating cavity for accommodating the LED driving part is formed between the heat dissipation part and the heat dissipation ribs. The LED driving part is located in the accommodating cavity. The spotlight module sends commands to the LED driving part through the control part, and changes the light emitting intensity and light emitting color of the LED emitting part through the LED driving part. When the spotlight works, heat is mainly generated by the LED driving part and the LED emitting part of the spotlight module. The heat generated by the LED emitting part can be dissipated outward, transferred to the heat dissipation groove through the groove between the fixing ribs, and transferred outward through the heat dissipation groove. The heat generated by the LED driving part is transferred to other positions in the inner cavity of the housing through the heat dissipation part, accelerating the heat dissipation efficiency of the LED driving part. The way of fixing the LED driving part in the accommodating cavity makes the structure in the housing simpler and more convenient for the production and processing of the housing.

[0010] Preferably, there are several fixing ribs. The several fixing ribs are arranged at equal circumferential intervals with the axis of the housing as the center on the side wall of the fixing part. The fixing ribs are further provided with inclined side walls that can abut against the side surface of the condenser cover. When the LED emitting part is connected to the fixing part, the side wall of the condenser cover abuts against the inclined side wall of the fixing rib. The several fixing ribs can further enhance the connection strength of the fixing part in the housing. The inclined side walls on the fixing ribs can play a role in guiding and positioning the condenser cover, facilitating the installation of the condenser cover and the LED emitting part onto the fixing part.

[0011] Preferably, a first plane is provided on the heat dissipation part. The first plane coincides with the axis of the housing and is perpendicular to the bottom surface of the heat dissipation part. The connecting pieces are symmetrically arranged on the heat dissipation part with the first plane as the symmetry plane. The connecting piece includes a first connecting piece and a second connecting piece. The acute angle formed by the first connecting piece and the first plane is smaller than the acute angle formed by the second connecting piece and the first plane. The connecting pieces are symmetrically arranged and connected between the heat dissipation part and the housing, making the force on the heat dissipation part more uniform and increasing the connection strength between the heat dissipation part and the housing. There are two connecting pieces, which can further increase the connection strength between the heat dissipation part and the housing.

[0012] Preferably, both the control part and the end cap are fixedly connected to the end face of the heat dissipation part by bolts. A control switch is provided on the control part, and a slot hole is provided on the end cap. The control switch passes through the slot hole and can slide in the slot hole to adjust the brightness and / or color of the spotlight. The control part and the end cap are both bolted to the heat dissipation part, which makes it easier to fix the control part and the end cap on the housing. The slot hole on the end cap exposes the control switch outside the housing, and the user can toggle the control switch to control different working modes of the spotlight. For example, the user can slide the control switch in the slot hole. The control switch has 3-5 gears. When the control switch is in different gears, the spotlight can present different brightness and colors.

[0013] Preferably, the width of the heat dissipation rib near the fixing part is greater than the widths of both ends of the heat dissipation rib. The heat generated by the LED light-emitting part needs to be quickly transferred to avoid heat accumulation, which affects the brightness and lifespan of the spotlight. The width of the heat dissipation rib near the fixing part is greater than the width of the end of the heat dissipation rib. After the heat on the LED light-emitting part is transferred to the heat dissipation groove formed by the heat dissipation rib through the fixing part, the width of the heat dissipation groove at the heat concentration part is small, which speeds up the transfer of the heat in the heat dissipation groove along the heat dissipation groove to both ends of the housing, avoiding heat accumulation.

[0014] Preferably, it further includes a connecting rod. The housing is provided with a clearance slot for the connecting rod to pass through. An installation piece is provided at the end of the connecting rod. An installation part is also provided between the two second connecting pieces. The installation part is U-shaped. Both ends of the U-shaped installation part are connected to the housing and the installation part also abuts against the second connecting piece. The installation piece is located inside the installation part and is bolted to the bottom surface of the installation part. A universal joint is provided between the connecting rod and the installation piece. In the vertical direction, one end of the housing away from the universal joint is inclined downward. The setting of the installation piece can increase the connection strength of the connecting rod. The setting of the universal joint enables the spotlight to rotate on the connecting rod, facilitating the change of the projection direction of the spotlight. The spotlight is inclined downward. After the heat dissipated by the spotlight module at the front end of the spotlight is transferred to the hot air, the density of the hot air decreases, and the hot air moves upward along the heat dissipation gap and escapes from the heat dissipation gap between the end cap and the housing. The cold air enters the inner cavity of the spotlight from the heat dissipation gap between the condenser cover and the housing, forming convection in the spotlight and improving the heat dissipation efficiency of the spotlight.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the spotlight in this solution, heat dissipation gaps that can communicate with the outside are provided at both ends of the housing. The heat inside the housing can diverge to the outside along the heat dissipation grooves formed by the heat dissipation ribs, and the external air flow can also enter the inner cavity of the housing through the heat dissipation gaps, completing the energy exchange between the inside of the housing and the external environment, achieving the purpose of quickly dissipating heat from the spotlight, and avoiding heat accumulation on the lamp, which affects the lifespan and brightness of the lamp.

[0024] The technical solutions of the present utility model will be further specifically described below through specific embodiments and in conjunction with the accompanying drawings:

[0025] Embodiment 1

[0026] As Figures 1 - 6Shown is an embodiment of an LED spot lamp facilitating heat dissipation, including a housing 1, an end cap 2, and a spot lamp module. The spot lamp module includes a condenser cover 3. Inside the housing 1 cavity, there are several heat dissipation ribs 7 arranged equidistantly in a circular pattern with the axis of the housing 1 as the center. The condenser cover 3 and the end cap 2 are respectively located at the front end and the rear end of the housing 1. The housing 1, the end cap 2, and the condenser cover 3 are coaxial, and the radii of the end cap 2 and the condenser cover 3 are both smaller than the inner cavity radius of the housing 1, so as to form heat dissipation gaps at both ends of the housing 1. Inside the housing 1 cavity, there is also a fixing module, which is connected to the housing 1 and is used to fix the spot lamp module.

[0027] The working principle or process of this embodiment: The groove formed between two heat dissipation ribs 7 inside the housing 1 cavity is a heat dissipation groove. When the spot lamp is working, when the heat generated by the spot lamp module dissipates outward, first, the heat will accumulate in the heat dissipation groove formed by two adjacent heat dissipation ribs 7. And the distribution of heat in the heat dissipation groove is that the heat closer to the spot lamp module is more, and the heat farther from the spot lamp module is less. And as the spot lamp continues to work, the spot lamp module continuously generates heat, causing the heat to transfer towards both ends of the heat dissipation groove in the heat dissipation groove. Since the radii of both the condenser cover 3 and the end cap 2 are smaller than the inner cavity radius of the housing 1, heat dissipation gaps communicating with the outside are formed at both ends of the housing 1. The heat in the heat dissipation groove can dissipate to the outside along the heat dissipation gaps at both ends of the housing 1, completing the heat exchange between the inside of the housing 1 cavity and the outside, and achieving the purpose of spot lamp heat dissipation.

[0028] The beneficial effects of this embodiment: In this solution, the spot lamp is provided with heat dissipation gaps at both ends of the housing 1 that can communicate with the outside. The heat inside the housing 1 can dissipate to the outside along the heat dissipation grooves formed by the heat dissipation ribs 7, and the external air flow can also enter the housing 1 cavity through the heat dissipation gaps, completing the energy exchange between the inside of the housing 1 and the external environment, achieving the purpose of rapid heat dissipation of the spot lamp, and avoiding heat accumulation on the lamp, which affects the life and brightness of the lamp.

The two ends of the connecting piece are respectively connected to the heat dissipation part 9 and the heat dissipation ribs 7. The heat dissipation part 9 is connected to the housing 1 through the connecting piece. The bottom surface of the heat dissipation part 9 abuts against the LED driving part 4. An accommodation cavity for accommodating the LED driving part 4 is formed between the heat dissipation part 9 and the heat dissipation ribs 7. The LED driving part 4 is located in the accommodation cavity. The spotlight module sends commands to the LED driving part 4 through the control part 6, and changes the light emitting intensity and light emitting color of the LED emitting part 5 through the LED driving part 4.

[0033] Specifically, there are several fixing ribs 10. The several fixing ribs 10 are arranged at equal circumferential intervals on the side wall of the fixing part 8 with the axis of the housing 1 as the center of the circle. The fixing ribs 10 are further provided with inclined side walls that can abut against the side surface of the condenser cover 3. When the LED emitting part 5 is connected to the fixing part 8, the side wall of the condenser cover 3 abuts against the inclined side wall of the fixing rib 10.

[0034] Specifically, the heat dissipation part 9 is provided with a first plane.

The connecting pieces are symmetrically arranged on the heat dissipation part 9 with the first plane as the symmetry plane. The connecting piece includes a first connecting piece 11 and a second connecting piece 12. The acute angle formed by the first connecting piece 11 and the first plane is smaller than the acute angle formed by the second connecting piece 12 and the first plane.

[0035] Specifically, both the control part 6 and the end cover 2 are fixedly connected to the end surface of the heat dissipation part 9 through bolts. The control part 6 is provided with a control switch 601. The end cover 2 is provided with a slot hole 201. The control switch 601 passes through the slot hole 201.

[0037] Advantages of this embodiment: The width of the heat dissipation gap is between 4 mm and 5 mm, and the heat dissipation effect inside the spotlight is the best. Moreover, it can prevent other sundries from entering the inner cavity of the housing 1 along the heat dissipation gap. The height of the heat dissipation ribs 7 is greater than the width of the heat dissipation gap, which can not only guide the heat dissipated outward from the heat dissipation grooves and the air flow entering the inner cavity of the housing 1 from the outside, but also further prevent external sundries from entering the inner cavity of the housing 1. The heat generated by the LED light-emitting part 5 is transferred to the heat dissipation grooves through the grooves between the fixing ribs 10 and then transferred outward through the heat dissipation grooves. The heat generated by the LED driving part 4 is transferred to other positions in the inner cavity of the housing 1 through the heat dissipation part 9, accelerating the heat dissipation efficiency of the LED driving part 4.

There are two connecting pieces, which can further increase the connection strength between the heat dissipation part 9 and the housing 1. The control part 6 and the end cover 2 are both bolted to the heat dissipation part 9, making it more convenient to fix the control part 6 and the end cover 2 on the housing 1.

The cold air enters the inner cavity of the spotlight from the heat dissipation gap between the condenser cover 3 and the housing 1, forming a convection inside the spotlight and improving the heat dissipation efficiency of the spotlight.
