Lighting fixture

The invention relates to a lighting fixture, in particular to a lighting fixture which can be freely assembled.

A Light Emitting Diode (LED) is a semiconductor component that converts current into light of a specific wavelength range. Light-emitting diodes are widely used in the field of illumination because of their high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life. For details, see Joseph Bielecki et al. Thermal Considerations for LED Components in an Automotive Lamp, document IEEE 2007, 23rd IEEE SEMI-THERM Symposium.

In the application of the light-emitting diode, it is usually necessary to provide a lighting fixture for changing the light field distribution of the light-emitting diode. However, existing LED lamps do not have a modular concept in terms of installation or assembly. For the design process of the luminaire, it is necessary to design various types of luminaires according to the needs of lighting to meet a variety of light field distributions, which will undoubtedly lengthen the development cycle of lighting fixtures and increase production costs.

In view of this, it is necessary to provide a lighting fixture that can be freely assembled.

A lighting fixture comprising at least two luminaire modules and connecting elements arranged side by side. Each luminaire module includes a lamp housing, a lamp cover and elastic fasteners. The lamp housing and the lamp cover together form a hollow cavity structure for accommodating the light source. The lamp housing includes a bottom surface and a side surface, away from the side One end of the bottom surface is provided with a support portion that extends toward the hollow cavity and is bent. A first opening is disposed on a side of the lamp housing, and a second opening is disposed on the support portion. The elastic fastener is disposed in the second opening such that the support portion abuts the lamp cover and fixes the lamp cover to the lamp housing. The connecting component is configured to pass through a corresponding first opening of two adjacent sides of each adjacent two light fixture modules and to fix the adjacent two light fixture modules.

Compared with the prior art, the present invention provides a first opening and a corresponding connecting component on the side of the lamp housing, and the connecting component can pass through the first opening between the two lamp modules to connect the adjacent two lighting modules. connect them. Thereby achieving flexible splicing and assembly of the luminaire. At the same time, the present invention provides a second opening on the support portion of the lamp housing, and the lamp housing and the lamp cover are combined by the elastic fastener to realize the convenience of assembly.

Referring to FIG. 1 and FIG. 2 , the lighting fixture 100 of the embodiment of the invention includes two lamp modules 11 and a connecting component 12 .

The lamp module 11 includes a lamp housing 13, a lamp cover 14 and an elastic fastener 15.

Please refer to Figure 3 together. The lamp housing 13 has a rectangular parallelepiped structure having a bottom surface 131 and four side surfaces 132. The bottom surface 131 and the four side surfaces 132 together define a hollow cavity for accommodating a light source (not shown). A support portion 133 extending toward the hollow cavity and bent at one end of the side surface 132 away from the bottom surface 131 is provided for supporting the lamp cover 14. At least two first openings 134 are disposed on the four sides 132 of the lamp housing 13. In this embodiment, four first openings 134 are disposed on each side of the lamp housing 13, and the four first openings 134 are distributed at four corner positions of the rectangular side. At least four second openings 135 are provided on the support portion 133. In this implementation In the example, three second openings 135 are respectively disposed on the longer sides of the lamp housing 13 , and two second openings 135 are respectively disposed on the shorter sides of the lamp housing 13 .

The lamp cover 14 is disposed at an opening portion of the hollow body formed by the bottom surface 131 and the four side surfaces 132, and is supported by the support portion 133. The lampshade 14 is a light transmissive plate made of resin, epoxy resin, silicone rubber, high molecular polymer, transparent polyester optical material, polycarbonate, PET or PMMA. In the present embodiment, the lamp cover 14 is made of PMMA material.

The connecting member 12 is a set of mutually corresponding screws 121 and nuts 122. As shown in FIG. 2, the two long sides of two adjacent lamp modules 11 are attached to each other, so that the four first openings 134 of the two lamp modules 11 are corresponding to each other. The screw 121 passes through the first opening 134 between the two lamp modules 11, and then the two lamp modules 11 are fixed together by the nut 122.

The elastic fastener 15 is a U-shaped elastic piece. As shown in FIG. 4, it includes a U-shaped body 151, and a first extending surface 152 and a second extending surface 153 extending from the U-shaped body 151. The first extension surface 152 and the second extension surface 153 are perpendicular to the U-shaped body 151. The length of the first extension surface 152 extends longer than the length of the second extension surface 153. The elastic fastener 15 is used to fix the lamp cover 14 to the lamp housing 13, as shown in FIG. In use, the lamp cover 14 is first placed in the opening portion of the hollow body in the lamp housing 13, and is supported by the support portion 133. The U-shaped body 151 of the elastic fastener 15 is then inserted into the second opening 135, and the first extended surface 152 covers the outer surface of the lamp cover 14 for tightly bonding the lamp cover 14 to the lamp housing 13. Its second extension surface 153 covers the support portion 133 so that the elastic fastener 15 does not completely sink into the second opening 135. Due to the elastic force between the two ends of the U-shaped body 151, it can The support portion 133 is brought to the side of the lamp cover 14 so that the lamp cover 14 is tightly fixed to the surface of the lamp housing 13. Moreover, since the distance between the two sides of the U-shaped body 151 gradually increases from the bottom toward the extending surface, when the U-shaped body 151 is inserted into the second opening 135, due to the width of the second opening 135 The U-shaped body 151 and the lamp housing 13 have a lateral elastic pressure, and as the insertion depth of the U-shaped body 151 increases, the contact pressure between the U-shaped body 151 and the lamp housing 13 gradually increases. That is, the friction between the U-shaped body 151 and the lamp housing 13 also increases. This frictional force causes the elastic fastener 15 to not fall out of the second opening 135 and lose its holding action. At the same time, due to the contact pressure between the U-shaped body 151 and the lamp housing 13, the contact pressure can make the contact between the lamp housing 13 and the lamp cover 14 more tight, so that the lamp cover 14 is better fixed to the lamp housing 13 . In addition, in order to prevent the elastic fastener 15 from falling off in the second opening 135, a buckle 154 may be disposed on one end of the U-shaped body 151 near the first extending surface 152, when the U-shaped body 151 is fully inserted into the second When the opening 135 is opened, the buckle 154 can catch the lamp housing 13 from the inner side of the second opening 135, so that the elastic fastener 15 does not fall off from the second opening 135. The distance between the buckle 154 and the first extension surface 152 is greater than the thickness of the lamp housing 13. Preferably, the elastic fastener 15 of the embodiment is made of a metal material, which has better strength and toughness, so that the function of fixing the lamp cover 14 to the lamp housing 13 can be better achieved. The elastic fastener 15 is not limited to the U-shaped elastic piece of the embodiment, and may be other fixing devices, such as screws or nuts or baffles, as long as it can better fix the lamp cover 14 to the lamp housing. The purpose of 13 can be.

Preferably, the width of the top of the U-shaped body 151 of the elastic fastener 15 is slightly larger than the width of the bottom of the U-shaped body 151, that is, at the top of the U-shaped body 151. The distance between the extension surface 152 and the second extension surface 153 is slightly larger than the width of the bottom of the U-shaped body 151 for increasing the contact pressure between the U-shaped body 151 and the lamp housing 13.

Preferably, the width of the bottom of the U-shaped body 151 of the elastic fastener 15 is smaller than the width of the second opening 135 for inserting the U-shaped body 151 into the second opening 135.

In order to facilitate the disassembly of the elastic fastener 15, a corresponding third opening 136 is formed in the side of the lamp housing 13. The distance between the third opening 136 and the supporting portion 133 is smaller than the bottom of the U-shaped body 151 to the second extension. The distance between the faces 153. The third opening 136 is mainly used for the disassembly of the elastic fastener 15. That is, the elastic fastener 15 is conveniently detached from the lamp housing 13 to separate the lamp cover 14 from the lamp housing 13. At the time of disassembly, a long-shaped rigid article is inserted into the third opening 136, and then one end of the U-shaped body 151 is pressed. The U-shaped body 151 will be deformed to be deformed. When the U-shaped body 151 is deformed sufficiently large, the second extended surface 153 of the elastic fastener 15 will extend into the second opening 135, thereby disassembling the entire elastic fastener 15. After the elastic fastener 15 is disassembled, it will not fall outward, but will fall inside the lamp housing 13, thereby reducing the unnecessary drop and loss of the elastic fastener 15 during the disassembly process, facilitating the disassembling personnel. .

The lighting fixture 100 can further include a light source (not shown) including a fluorescent lamp, a cold cathode fluorescent lamp, an incandescent lamp, a gas discharge lamp, a halogen lamp, and a light emitting diode.
