Description

Technical Field

[0001] The present invention relates to the technical field of industrial lighting, and in particular to an explosion-proof LED lighting fixture with multiple installation modes. Background Art

[0002] During the design and manufacturing process of lighting fixtures, multiple LED lamp beads are usually set on an aluminum substrate. In order to allow the light emitted by the LED lamp beads to be refracted and reflected according to the designed light path direction, lenses are also set in front of the LED lamp beads, and a lens is set corresponding to each LED lamp bead.

[0003] In order to stably mount the lens in front of the LED lamp bead, a mounting bracket is usually provided, and a number of lenses are placed on the mounting bracket, and then the mounting bracket with the lenses is fixed on the aluminum substrate.

[0004] A light-transmitting gap forms between the contact surface of the lens and the aluminum substrate. Light from the LEDs easily leaks through this gap, causing light leakage. To prevent this, a colloid is traditionally applied between the contact surface of the lens and the aluminum substrate. This colloid creates a tighter connection between the lens and the aluminum substrate, thus filling the gap.

[0005] However, apart from the time and labor consuming nature of the traditional method during production, during long-term use of the lamp, the LED lamp beads will emit a large amount of heat, causing the colloid to age and fall off easily, thereby causing the light-transmitting gap between the lens and the aluminum substrate to reappear, causing light leakage again and affecting the light output effect of the lamp.

[0006] Therefore, it is necessary to redesign the above-mentioned traditional structure and improve the structure to replace the traditional production method of filling the light-transmitting gap by coating colloid. Summary of the Invention

[0024] like Figure 1 As shown, the present invention discloses an explosion-proof LED lighting fixture 10 with multiple installation methods, which includes: a lamp body 100, a power cover 200, a transparent member 300 (such as Figure 5 shown).

[0025] like Figure 5 As shown, the lamp body 100 is a cavity structure with two ends open. A partition 110 is provided in the cavity of the lamp body 100. The partition 110 separates the cavity to form a power cavity 120 and a light source cavity 130. The power cavity 120 is provided with a power supply component 140, and the light source cavity 130 is provided with a light source component 150. The power cover 200 is provided at the opening of the power cavity 120, and the transparent member 300 is provided at the opening of the light source cavity 130. Figure 5 As shown, a wire hole 111 is provided on the partition 110 , and the wires between the power supply assembly 140 and the light source assembly 150 are electrically connected through the wire hole 111 .

[0026] like Figure 1 As shown, a hanging bracket 400 and a platform bracket 500 are rotatably provided on the side wall of the lamp body 100. The rotation axis of the hanging bracket 400 is parallel to and coincides with the radial line of the lamp body 100, and the rotation axis of the platform bracket 500 is parallel to but does not coincide with the radial line of the lamp body 100. A front cover 600 is provided on one end face of the transparent part 300 of the lamp body 100.

[0027] The light source assembly 150 includes: an aluminum substrate 700 (such as Figure 10 As shown), several lens monomers 800 (as shown Figure 6 and Figure 7 As shown), lens mounting frame 900 (as shown Figure 6 and Figure 7 As shown). Several lens monomers 800 are mounted on a lens mounting frame 900, which is fixed on an aluminum substrate 700. Several lens monomers 800 correspond to the LED lamp beads 701 on the aluminum substrate 700 (as shown). Figure 10 shown).

[0028] like Figure 8 As shown, specifically, the lens mounting frame 900 is twisted to form a spiral spring structure, and a spiral channel 910 is formed along the extension direction of the lens mounting frame 900. A plurality of mounting slots 911 are sequentially spaced apart on the spiral channel 910, and a plurality of lens monomers 800 are correspondingly arranged in the plurality of mounting slots 911.

[0029] In the non-installed state, the lens mounting frame 900 is a three-dimensional shape with a height (such as Figure 7 shown); In the installed state, the lens mounting frame 900 shrinks from a three-dimensional shape to a planar shape and is attached to the aluminum substrate 700 . The aluminum substrate 700 generates elastic force along the central axis so that the lens monomers 800 are tightly pressed against the aluminum substrate 700 .

[0030] like Figure 9 As shown, the lens monomer 800 has an LED receiving cavity 810 , and the LED lamp bead 701 is received in the LED receiving cavity 810 . A pressing plane 811 is formed at the cavity opening of the LED receiving cavity 810 , and the pressing plane 811 is pressed on the aluminum substrate 700 .

[0031] like Figure 9 As shown, the side wall of the lens monomer 800 forms a conical guide surface 820, and the side wall of the lens monomer 800 is provided with an annular groove 830. The scroll channel 910 is composed of two scroll elastic sheets 901 (such as Figure 8 As shown in the figure, the lens monomer 800 is elastically clamped between two bath roll elastic sheets 901 through the annular clamping groove 830.

[0032] The outer ring of the lens mounting frame 900 is tightened by screws 920 (such as Figure 6 as shown) is fixed on the aluminum substrate 700.

[0033] The explosion-proof LED lighting fixture 10 of the present invention has multiple installation methods and can be used in a variety of ways depending on the application environment: like Figure 2As shown, the lamp body 100 can be mounted on the platform using the platform bracket 500 and used as a platform-fixed lamp; like Figure 3 As shown, the lamp body 100 can be hung on the ceiling using a hanging bracket 400 and used as a hanging lamp; like Figure 4 As shown, the front cover 600 can be used to hide the lamp body 100 in the groove and used as a downlight.

[0034] The following describes the assembly of some parts of the explosion-proof LED lighting fixture 10 with various installation methods. like Figure 6 and Figure 7 As shown, several lens monomers 800 are sequentially arranged and spaced apart along the extension line of the lens mounting frame 900 and installed in the scroll channel 910; the scroll channel 910 is formed by two scroll elastic sheets 901. Following the guidance of the conical guide surface 820, the two scroll elastic sheets 901 will slightly expand outward, so that the annular groove 830 can be engaged with the installation groove 911 between the two scroll elastic sheets 901. When installed in place, the two scroll elastic sheets 901 recover their elastic deformation to clamp the lens monomer 800; After the lens units 800 are completely mounted on the lens mounting frame 900, the lens mounting frame 900 is now in a highly three-dimensional shape. It can be seen that the lens mounting frame 900 with a spiral spring structure is in a highly three-dimensional shape in the direction of the central axis. like Figure 10 As shown, a lens mounting frame 900 having a plurality of lens units 800 is mounted on an aluminum substrate 700. The lens mounting frame 900 is compressed along the central axis and pressed against the aluminum substrate 700, causing the lens mounting frame 900 to change from a three-dimensional shape to a planar shape (the lens mounting frame 900 generates an elastic force along the central axis). The outer ring of the lens mounting frame 900 is fastened to the aluminum substrate 700 using fastening screws 920. Due to the elastic force, the pressing surface 811 at the opening of the LED receiving cavity 810 can be tightly pressed against the aluminum substrate 700 without generating any light leakage gaps, and the LED lamp bead 701 is correspondingly received in the LED receiving cavity 810. At this point, the lens mounting frame 900 having a plurality of lens units 800 can be mounted on the aluminum substrate 700 without the need to adopt the traditional method of coating the contact surface of the lens and the aluminum substrate with colloid. This not only reduces the tedious gluing process, but also prevents the generation of light-transmitting gaps due to aging of the colloid, thereby preventing light leakage.

[0035] The present invention improves the structure of the light source assembly 150. On the one hand, it can quickly clip a plurality of lens monomers 800 onto the lens mounting frame 900 for use. On the other hand, it replaces the traditional gluing method and utilizes the elastic force generated by the deformation of the lens mounting frame 900 to press the lens monomers 800 onto the aluminum substrate 700. The process is simple, the service life is long, and the structure is reliable and stable.

[0036] like Figure 5 As shown, in the present invention, a power supply waterproof seal ring 121 is provided at the opening of the power supply cavity 120, and the power supply cover 200 seals the power supply cavity 120 via the power supply waterproof seal ring 121. A light source waterproof seal ring 131 is provided at the opening of the light source cavity 130, and the transparent member 300 seals the light source cavity 130 via the light source waterproof seal ring 131. By providing the power supply waterproof seal ring 121 and the light source waterproof seal ring 131, a better waterproof sealing effect can be achieved, thereby extending the overall service life of the lamp.

[0037] In the present invention, the front cover 600 is a circular ring structure, and a protective net 610 (such as Figure 2 and Figure 3 As shown) to protect the transparent member 300. By providing a protective net 610 at the center of the front cover 600, the transparent member 300 (glass) can be protected to prevent it from being shattered by collision with external objects.

[0038] like Figure 5 As shown, in the present invention, a cable entry hole 201 is provided on the power cover 200, and a cable gland 202 is provided at the cable entry hole 201. The cable gland 202 plays a role in preventing dust and water, and also plays a role in fixing the cable.

[0039] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
