Description

Technical Field

[0001] This invention relates to the field of stage lighting technology, and more particularly to a novel modular lighting fixture. Background Technology

[0002] Generally, modular lamp units in existing technologies are not equipped with cooling fans, and only have heat sinks on the back of the lamp unit, resulting in poor heat dissipation. In order to ensure the stable operation of the lamp unit, the number of LEDs on the lamp board is limited, resulting in a smaller area of ​​LEDs on the lamp board. If large-area panel light splicing is required, more lamp units need to be assembled. Therefore, existing modular lighting fixtures are significantly reduced in both splicing and assembly efficiency and cost. Summary of the Invention

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0023] As attached Figure 1 To be continued Figure 3 As shown, a novel modular lighting fixture includes a frame 1. The frame 1 has two opposing and interconnected first connecting parts 11 and second connecting parts 12. A base 2 is fixedly connected or integrally formed between the two opposing first connecting parts 11. A plurality of lamp body units 3 are fixedly connected between the two opposing second connecting parts 12. A power supply box 4 is fixedly connected to the base 2 and electrically connected to each of the lamp body units 3. A plurality of cooling fans 5, corresponding one-to-one with each of the lamp body units 3, are fixedly installed on the base 2, and the power supply box 4 is electrically connected to each of the cooling fans 5. This modular lighting fixture equips each lamp body unit 3 with a cooling fan 5, which greatly improves the heat dissipation effect of the lamp body unit 3. It also allows for a larger number of LED chips, increasing the area of ​​the LED chips on the lamp panel. With the same frame 1 area, the number of lamp body units 3 can be reduced, thereby improving assembly efficiency and reducing manufacturing costs.

[0024] As attached Figure 3 As shown, the cooling fan 5 is disposed between the lamp body unit 3 and the base 2. Specifically, the upper end face of the base 2 is fixedly connected to the power supply box 4, and the lower end face of the base 2 is fixedly connected to the cooling fan 5, so that the air outlet of the cooling fan 5 is closer to the heat sink 31 on the back of the lamp body unit 3, thereby further improving the heat dissipation efficiency.

[0025] As attached Figure 5 As shown, the base 2 has several stop blocks 21 arranged at intervals along its length on both sides. The cooling fan 5 is located between the stop blocks 21 on both sides. An air intake channel can be formed between adjacent stop blocks 21. It should be further noted that the interval between adjacent stop blocks 21 can be set to a range of 2 to 5 mm to effectively prevent the operator's fingers from accidentally touching the fan.

[0026] As attached Figure 2As shown, several heat sinks 31 are arranged side by side at intervals on the side of the lamp body unit 3 near the cooling fan 5. A heat dissipation air duct 32 is formed between adjacent heat sinks 31, with both ends extending along the direction close to the second connecting part 12. It can be understood that the heat sinks 31 and the second connecting part 12 are arranged perpendicularly, so that the heat dissipation air duct 32 formed by the heat sinks 31 and the adjacent heat sinks 31 extends along the length direction of the lamp body unit 3, allowing the cold air to have sufficient heat exchange time in the heat dissipation air duct 32, so as to achieve the effect of sufficient heat dissipation.

[0027] As attached Figure 5 As shown, the second connecting part 12 is provided with a baffle 121 having a plurality of ventilation holes 120. The ventilation holes 120 are connected to the heat dissipation duct 32 opposite to them, so that the air after heat exchange flows out through the ventilation holes 120 along the heat dissipation duct 32, which is conducive to heat dissipation of the lamp body unit 3.

[0028] As attached Figure 3 and attached Figure 5 As shown, the base 2 is fixedly provided with a plurality of annular flanges 22 corresponding one-to-one with the lamp body unit 3. The lamp body unit 3 has a first receiving cavity 30, and the power supply box 4 has a second receiving cavity 40. The annular flanges 22 are provided with a channel 221 that connects the first receiving cavity 30 and the second receiving cavity 40. The channel 221 is used for the power cord to pass through so that the power supply box 4 and the lamp body unit 3 are electrically connected.

[0029] Multiple annular flanges 22 are spaced apart and located between two rows of stop blocks 21, so that the annular flanges 22 and the two rows of stop blocks 21 together form a receiving space that is compatible with the cooling fan, making the structure more compact.

[0030] As attached Figure 3 As shown, the back of the lamp body unit 3 has a first opening communicating with the first receiving cavity 30. A first plug terminal 6 is provided at the first opening. A second plug terminal 7 that can be plugged into the channel 221 of the annular flange 22 is provided. When the lamp body unit 3 is fixed to the base 2, the first plug terminal 6 and the second plug terminal 7 are kept plugged in, so that the power box 4 and the lamp body unit 3 are electrically connected. The power box 4 and the lamp body unit 3 can be quickly electrically connected by plugging in the plug terminal.

[0031] As attached Figure 3As shown, the free end of the annular flange 22 is sealed to the edge of the first opening through the first sealing ring 8. Preferably, the free end of the annular flange 22 is provided with a first groove for the first sealing ring 8 to be accommodated, and the outer edge of the first opening is provided with a second groove for the first sealing ring 8 to be accommodated. When sealed, the first groove and the second groove together form a first waterproof groove that seals and fits the first sealing ring 8, so that the first opening is in the sealed channel 221. After the first accommodating cavity 30, the channel 221 and the second accommodating cavity 40 are connected, they can be in a sealed waterproof space, which further increases the waterproof safety performance of the lamp.

[0032] As attached Figure 3 As shown, the second receiving cavity 40 has a second opening, and the edge of the second opening is sealed to the base 2 by a second sealing ring 9. Similarly, a third groove is provided on the base 2 for the second sealing ring 9 to be received, and a fourth groove is provided at the outer edge of the second opening for the second sealing ring 9 to be received. When sealed, the third groove and the fourth groove together form a second waterproof groove that seals and fits the second sealing ring, thereby enhancing the sealing connection between the power box 4 and the base 2.

[0033] In this embodiment, multiple modular lamps can be spliced ​​together to form panel lights according to the design requirements of stage lighting, thus enriching the stage lighting effects.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various equivalent changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
