Description

Technical Field

[0001] This utility model belongs to the field of stage lighting technology, specifically relating to a multi-cavity heat dissipation LED waterproof stage lighting fixture. Background Technology

[0002] LEDs (Light Emitting Diodes) are widely used in stage lighting due to their high luminous efficiency, fast response speed, excellent combined rendering effects, low heat radiation, long lifespan, energy saving, and environmental friendliness. In recent years, with the rapid development of urban construction and the cultural and tourism industry, the application of LED stage lighting in urban beautification and landscape lighting has become increasingly widespread, and the issues of sealing, waterproofing, and heat dissipation have received increasing attention. Especially in high-power LED stage lighting, key components such as the electronic transformer, driver PCB board, and light-emitting module generate large rated currents during operation, causing most of the output power to be converted into heat. These electrical components are usually integrated into the same sealed cavity. If effective heat dissipation measures are not taken, the accumulated heat will cause the temperature of the electronic components or LED chips to rise sharply, thereby affecting the luminous efficiency of the lighting, causing malfunctions, or shortening its lifespan. Therefore, efficient heat dissipation has become a core challenge to ensure the stable operation of LED stage lighting.

[0003] In existing technologies, a common solution to the heat dissipation problem of LED lighting fixtures is to adjust the operating current of the LED fixture using temperature sensors and control circuits. When an increase in temperature is detected, the LED current is automatically reduced to lower power consumption. However, while this method can slow down heat accumulation, it inevitably reduces the brightness of the LED fixture, failing to meet the constant high brightness requirements of stage lighting. Another common solution is to add a cooling fan inside the fixture, using forced convection to accelerate heat dissipation. However, fans generate significant noise when running at high speeds, especially in high-power scenarios, which not only interferes with the low-noise environment of stage performances but may also affect the user experience. Therefore, both of these heat dissipation methods have obvious drawbacks: the current control solution sacrifices lighting performance, while the fan solution introduces noise pollution. Neither can simultaneously achieve efficient heat dissipation, low noise, and stable lighting requirements, and thus is not the optimal solution.

[0004] Therefore, there is an urgent need to provide a multi-cavity heat dissipation LED waterproof stage lighting fixture to effectively address the shortcomings of existing heat dissipation solutions. Summary of the Invention

[0005] To address the problems in related technologies, this utility model proposes a multi-cavity heat dissipation LED waterproof stage lighting fixture. The fixture is divided into multiple relatively independent sealed cavities, such as a light source module, a power supply module, and a control module. Each cavity dissipates heat independently, and there are sealed channels for wiring connections between the cavities, thereby solving the technical problems such as poor heat dissipation efficiency of existing LED stage lighting fixtures.

[0006] The technical solution of this utility model is implemented as follows: a multi-cavity heat dissipation LED waterproof stage lighting fixture includes a housing body, and a light source module, a power supply module and a control module disposed on the housing body; the light source module is disposed on the first end face of the housing body; the power supply module and the control module are disposed on the second end face of the housing body, and are disposed at intervals.

[0007] The light source module includes a lens assembly, a light source assembly, and a heat sink assembly assembled sequentially. The lens assembly and the heat sink assembly are fitted together to form a first sealed cavity, and the light source assembly is placed in the first sealed cavity. The power module includes a power supply assembly and a power module housing surrounding it. The power module housing and the outer shell body enclose a second sealed cavity. The control module includes a drive assembly and a control module housing surrounding it. The control module housing and the outer shell body enclose a third sealed cavity.

[0008] The outer shell body is provided with a longitudinal wiring channel and a transverse wiring channel; the first sealing cavity is connected to the second sealing cavity and the third sealing cavity respectively through the longitudinal wiring channel; the second sealing cavity is connected to the third sealing cavity through the transverse wiring channel.

[0009] This invention divides the lamp into three independent sealed cavities: a light source module, a power supply module, and a control module, physically isolating the main heat sources such as the LED light-emitting components, power transformer, and drive circuit. Each cavity forms its own heat dissipation unit, avoiding the problem of heat accumulation in traditional integrated structures and effectively improving the lamp's heat dissipation efficiency. Furthermore, the multi-cavity structure allows for the separation of the high-voltage and low-voltage power supply lines, enhancing the lamp's internal electromagnetic interference resistance.

[0010] As a further improvement to the above solution, the first end face of the outer shell body is provided with a concave accommodating cavity; the light source module is located at the opening of the accommodating cavity, and the heat sink assembly of the light source module extends into the accommodating cavity; the outer periphery of the outer shell body is provided with a mating interface for lamp hanging or splicing between lamp bodies.

[0011] The longitudinal line channels are provided in multiple ways, symmetrically distributed along the cavity wall and extending from the first end face to the second end face, respectively corresponding to the positions of the power module and the control module; the transverse line channels are located at the bottom of the cavity and are perpendicular to the extension direction of each longitudinal line channel.

[0012] As a further improvement to the above solution, the heat sink assembly is provided with a connection interface corresponding to the longitudinal wiring channel. The wiring passes through the connection interface to connect to the light source assembly, and a first sealing strip of a matching shape is provided at the connection interface. The connection interface on the heat sink assembly facilitates the passage of wiring and enables the light source assembly to be electrically connected to the power supply assembly and the drive assembly respectively. At the same time, the first sealing strip of a matching shape effectively ensures a waterproof seal and prevents water from entering the lamp body.

[0013] Two transverse wiring channels are provided, with a ventilation space between them. Each transverse wiring channel includes a strip-shaped protrusion ring extending from the bottom of the accommodating cavity. Both ends of the strip-shaped protrusion ring have wiring ports connecting to the second and third sealed cavities, respectively. A second sealing strip and a waterproof baffle are also sequentially provided on the strip-shaped protrusion ring. The power module and control module are independent of each other, allowing for distributed heat dissipation and improved heat dissipation efficiency. Simultaneously, the high and low voltage circuits of the lamp can be separated, reducing electrical frequency interference. A wiring connection channel is provided between the two modules, and this connection channel is equipped with a waterproof baffle and sealing strip to prevent water from entering the lamp body.

[0014] As a further improvement to the above solution, an air intake fan is provided in the ventilation space in the middle of the outer shell body, and exhaust fans are provided on both sides of the outer shell body; the air intake fan and the exhaust fan form a circulating heat dissipation air duct, and the airflow is introduced into the accommodating cavity by the air intake fan, passes through the radiator assembly, and is discharged by the exhaust fan.

[0015] As a further improvement to the above solution, the heat sink assembly includes a heat sink with elongated, strip-shaped heat dissipation fins installed facing the airflow direction, allowing airflow to follow the extension direction of the fins. Air is drawn in centrally by an intake fan located at the center of the main casing, guiding the airflow along the fin extension direction towards heat dissipation. Heat is then exhausted by exhaust fans at both ends, meeting the heat dissipation requirements of the lamp. This heat dissipation method can effectively improve heat dissipation efficiency by up to 30%.

[0016] As a further improvement to the above solution, the light source assembly includes an LED light-emitting board and a thermal pad; the LED light-emitting board has several pieces, each LED light-emitting board is equipped with multiple LED beads, and the LEDs are controlled to be turned on or off in different areas; the LED light-emitting board is tightly attached to the end face of the heat sink through the thermal pad; the thermal pad provides full contact and thermal connection between the LED light-emitting board and the heat sink, which is conducive to quickly guiding heat to the heat sink and removing the heat through the circulating cooling air duct.

[0017] The radiator assembly further includes a third sealing strip that extends along the circumferential edge of the radiator's end face; the lens assembly is sealed to the radiator via the third sealing strip.

[0018] As a further improvement to the above solution, both the air inlet of the air intake fan and the air outlet of the exhaust fan are equipped with grid-like or mesh protective covers. The protective covers effectively prevent foreign objects from entering and extend the lifespan of the lamp body.

[0019] As a further improvement to the above solution, the power module carries the high-voltage power supply line, and the control module carries the low-voltage control line; the two are separately wired through a horizontal wiring channel. The power module and control module are independent of each other, allowing for distributed heat dissipation and improved heat dissipation efficiency. Simultaneously, the high and low voltage circuits of the lighting fixture can be separated, reducing electrical frequency interference.

[0020] As a further improvement to the above solution, the power supply component includes a switching power supply and a power module fan; the drive component includes a light source driver board, a fan control board, a power signal conversion board, a network control board, and a control module fan. The light source driver board primarily controls the lamp's light emission, brightness adjustment, color adjustment, and effect module control; the fan control board primarily controls and adjusts the cooling voltage (or speed) of all fans in the lamp according to the lamp's heat dissipation requirements; the network control board is mainly responsible for network connection and control; and the control module fan is used to blow air to cool the control module.

[0021] As a further improvement to the above solution, the power module also includes a power fixing plate; the switching power supply is fixed on the power fixing plate, a fan fixing plate is mounted above the power fixing plate, and the power module fan is installed on the fan fixing plate;

[0022] The control module also includes a drive fixing plate; the light source drive plate, fan control plate, power signal conversion plate, network control plate and control module fan are stacked on the drive fixing plate.

[0023] Beneficial effects:

[0024] (1) By dividing the luminaire into three independent sealed cavities—a light source module, a power supply module, and a control module—the main heat sources, such as the LED light-emitting components, power transformer, and drive circuit, are physically isolated. Each cavity forms its own heat dissipation unit, avoiding the problem of heat accumulation in traditional integrated structures. The first sealed cavity is dedicated to heat dissipation of the light source, while the second and third sealed cavities handle the heat generated by the power supply and control modules, respectively. Combined with longitudinal / lateral wiring channels, the wiring connections are realized, effectively improving the luminaire's heat dissipation efficiency, ensuring normal operation of the luminaire, and enhancing its luminous efficacy.

[0025] (2) The power supply module and the control module are placed in separate cavities, and the two are connected only through the wiring in the transverse wiring channel. The multi-cavity structure can separate the power supply lines of the high-voltage part and the low-voltage part of the lamp, improve the internal electromagnetic interference resistance of the lamp, and effectively enhance the stability of the lamp.
