Description

Technical Field

[0001] The utility model belongs to the field of stage lamps, and in particular relates to a stage lamp heat dissipation system and a stage lamp. Background Art

[0002] With the widespread application of stage lights in the market, high-pressure gas discharge bulbs have become one of the mainstream light sources used in stage lights. The high-pressure gas discharge bulbs used in stage lights in the stage and cultural tourism fields have high requirements for temperature control. The bulb area cannot be too cold or too hot. Overheating will cause the internal air pressure of the gas discharge lamp to rise and cause the bulb to explode. Overcooling will cause insufficient internal air pressure to affect the lighting effect.

[0003] Due to the use conditions of stage lights such as horizontal movement angle, vertical movement angle, movement speed, or staying at one angle for a long time, it is difficult to meet the requirement of uniform heating of the bulb temperature. For a long time, the heat dissipation problem has not been more effectively solved, which can easily lead to local heating or uneven heat dissipation of the high-pressure gas discharge bulb bulb, resulting in large temperature differences on the bulb glass surface and bursting due to the physical characteristics of expansion and contraction. It can also easily cause the bulb to turn partially white or partially black, reducing the luminous efficiency and shortening the service life.

[0004] At present, the cooling system of stage lights basically uses a fixed blower to blow air to the bulbs in a fixed position to dissipate heat. The cold air is basically blown continuously and fixedly into a certain point of the bulb, which will make the temperature of the blowing side of the bulb center lower than the temperature of the leeward side, resulting in a large temperature difference on both sides of the bulb, making the bulb partially white or partially black, resulting in reduced luminous efficiency and shortened bulb service life, and also increasing the risk of bulb explosion. Summary of the invention

[0005] The utility model aims to provide a stage lamp heat dissipation system and a stage lamp, which can evenly dissipate heat from a bulb, ensure the luminous efficiency and service life of the bulb, and reduce the risk of the bulb bursting.

[0006] The technical solution is as follows:

[0007] The heat dissipation system of a stage lamp comprises a main support, a rotating part, a driving mechanism, and a heat dissipation mechanism. The rotating part is rotatably arranged on the main support and is hollow; the heat dissipation mechanism is fixedly arranged on one side of the main support and is used to dissipate heat for the bulb; the driving mechanism is fixedly arranged on the other side of the main support and is used to drive the rotating part to rotate.

[0008] By adopting the above technical solution, the light bulb is installed through the rotating part, and then the rotation speed and direction of the driving mechanism are controlled by an external control program. The driving mechanism causes the light bulb to rotate at a uniform speed on the main bracket. Since the heat dissipation mechanism is fixed to one side of the main bracket, the heat dissipation mechanism can stably discharge air and evenly dissipate heat for the light bulb, thereby ensuring the luminous efficiency and service life of the light bulb and reducing the risk of the light bulb exploding.

[0009] In one embodiment, the driving mechanism includes a first driving motor and a driving wheel, the first driving motor is fixed on the main bracket, and the driving wheel is fixedly connected to the driving shaft of the first driving motor; the rotating member is configured as a driven wheel, and the driven wheel is rotationally connected to the driving wheel.

[0010] By adopting the above technical solution, the driving wheel is driven to rotate by the first driving motor, and then the driven wheel is driven to rotate synchronously. Since the light bulb is fixed on the driven wheel, the light bulb rotates synchronously to ensure uniform heat dissipation of the light bulb.

[0011] In one embodiment, the main bracket is provided with a clearance groove near one side of the driving mechanism, and the driving mechanism also includes a transition gear, the transition gear is at least partially passed through the clearance groove, and the transition gear is respectively connected to the driving wheel and the driven wheel gear.

[0012] By adopting the above technical solution, since the driving wheel is directly transmitted to the first drive motor, the driving wheel and the driving shaft of the first drive motor have the same direction of rotation. By setting a transition gear between the driving wheel and the driven wheel, the driven wheel is prevented from being directly connected to the driving wheel, thereby keeping the direction of rotation of the driving wheel and the driven wheel consistent, which is convenient for direct control of the direction of the light bulb.

[0013] In one of the embodiments, a support seat is further provided on the main support, and the support seat is hollow. The driven wheel is rotatably disposed on the support seat. A fixed pillar is also protruding from the main support, and the support seat is fixed on the fixed pillar, forming an installation distance between the support seat and the main support.

[0014] With the above technical solution, since the support base is hollow, there is an installation distance between the support base and the main bracket, so that the bottom of the bulb can be connected to the outside, thereby improving the heat dissipation inside the bulb.

[0015] In one of the embodiments, a heat dissipation bracket is fixedly provided on the main bracket, the heat dissipation bracket is located between the support seat and the main bracket, the heat dissipation bracket is hollow, and a heat sink is provided on one side of the heat dissipation bracket.

[0016] By adopting the above technical solution and arranging the heat dissipation bracket within the installation spacing, the heat dissipation effect on the light bulb is further improved.

[0017] In one of the embodiments, the middle portion of the heat dissipation bracket is convex, the heat dissipation bracket is inclined toward both ends along the middle portion, and the middle portion of the heat dissipation bracket is close to the bottom of the support base.

[0018] With the above technical solution, since both ends of the heat dissipation bracket are inclined toward the middle, the middle of the heat dissipation bracket is close to the bottom of the support base, so that the external airflow is guided into the bulb, further improving the heat dissipation effect of the heat dissipation bracket on the bulb.

[0019] In one of the embodiments, a line storage rack is further provided on the driven wheel, and the line storage rack is located at the outer periphery of the driven wheel.

[0020] By adopting the above technical solution, the circuit of the light bulb can be stored and fixed on the circuit storage rack. When the circuit storage rack rotates synchronously with the driven wheel, the circuit storage rack and the light bulb remain relatively still, thereby avoiding entanglement of the circuit.

[0021] In one of the embodiments, the heat dissipation mechanism includes a first fan, and a first air guide port is further provided above one side of the main bracket, and an air outlet of the first fan is directed toward the rotating member through the first air guide port.

[0022] By adopting the above technical solution, when the light bulb rotates at a uniform speed, the first fan always blows toward the outside of the light bulb through the first air guide port, and the first fan fixed on one side of the light bulb helps to maintain stable wind force, thereby accurately controlling the temperature of the outside of the light bulb.

[0023] In one embodiment, the heat dissipation mechanism also includes a second fan, and an air guide is also provided at the bottom of one side of the main bracket; a first air outlet and a second air outlet are provided at both ends of the air guide, the first air outlet is connected to the second air outlet, the air outlet of the second fan matches the first air outlet, and the second air outlet faces into the rotating part.

[0024] By adopting the above technical solution, when the light bulb rotates at a uniform speed, the second fan is always blown into the light bulb through the air guide, and the second fan fixed on one side of the light bulb helps to keep the wind force stable, thereby accurately controlling the temperature inside the light bulb, reducing the temperature difference between the inside and outside of the light bulb, further ensuring the service life of the light bulb, and preventing the light bulb from bursting.

[0025] A stage light comprises a light bulb and a stage light heat dissipation system as claimed in any one of the above claims, wherein the light bulb is mounted on a rotating member.

[0026] By adopting the above technical solution, the driving mechanism drives the rotating part to make the bulb rotate at a uniform speed, and then the fixed heat dissipation mechanism dissipates the heat of the bulb in all directions and evenly, thereby ensuring the luminous efficiency and service life of the bulb and reducing the risk of the bulb exploding.

[0040] like Figures 1 to 4 The stage lamp heat dissipation system shown includes a main bracket 10, a driving mechanism 30 of a rotating member 11, and a heat dissipation mechanism 40. The rotating member 11 is rotatably arranged on the main bracket 10, and the rotating member 11 is hollow; the heat dissipation mechanism 40 is fixedly arranged on one side of the main bracket 10, and the heat dissipation mechanism 40 is used to dissipate heat for the bulb 20, and the driving mechanism 30 is fixedly arranged on the other side of the main bracket 10, and the driving mechanism 30 is used to drive the rotating member 11 to rotate; the bulb 20 is installed through the rotating member 11, and then the speed and direction of the driving mechanism 30 are controlled by an external control program, and the driving mechanism 30 causes the bulb 20 to rotate at a uniform speed on the main bracket 10.

When the wire storage rack 112 rotates synchronously with the driven wheel 111, it is ensured that the wire storage rack 112 and the light bulb 20 remain in a relatively static state, thereby avoiding entanglement of the wires.
