As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The utility model provides a LED work light 10, as shown in figure 1 and figure 2, it includes: a base 100, a light source assembly 200, a fixing bracket 300, and a connection bracket 400. As shown in fig. 3, the base 100 is integrally formed, the base 100 includes a plurality of mounting plates 110 arranged side by side and a main body support plate 120 arranged at two sides of the mounting plates 110, a plurality of heat dissipation fins 130 are arranged on the mounting plates 110, a heat dissipation gap 131 is arranged between two adjacent heat dissipation fins 130, and the heat dissipation fins 130 and the main body support plate 120 are located at the same side of the mounting plates 110. The heat sink 130 has a draft angle of 1 to 3 °.

It is noted that the provision of the heat dissipation gap 131 facilitates air circulation, thereby achieving heat dissipation. Moreover, since the base 100 is integrally formed, the heat sink 130 and the mounting plate 110 are closely attached to each other, and compared with other connection methods such as welding, the integrally formed heat sink 130 and the mounting plate 110 can conduct heat better, thereby obtaining a better heat dissipation effect. After the integrally formed structure is adopted, the existence of the die drawing angle is particularly important, which is beneficial to the die drawing operation in the production process of the base 100 and can effectively prevent the radiating fins 130 from being scratched or even broken in the die drawing process.

As shown in fig. 5 and 6, the light source assembly 200 is disposed on the mounting plate 110 and away from the heat sink 130, and the light source assembly 200 includes: the LED light distribution plate 210, the light transmission plate 220 and the protective outer frame 230, the light transmission plate 220 is arranged on the installation panel 110, the LED light distribution plate 210 is arranged between the installation panel 110 and the light transmission plate 220, the LED light distribution plate 210 is attached to the installation panel 110, the protective outer frame 230 is arranged on the installation panel 110 through a positioning screw 231, and the protective outer frame 230 is pressed on the edge of the light transmission plate 220. During lighting, light emitted from the LED lighting board 210 is irradiated through the transparent plate 220, and during lighting, the LED lighting board 210 generates heat, and the heat is transferred to the mounting plate 110 and the heat sink 130 and then released to the outside.

As shown in fig. 2, the fixing bracket 300 includes a support arm 310, and the support arm 310 is connected to the base 100 by a fastening assembly 320. The connecting frame 400 (shown in fig. 7) is used to integrally connect the two bases 100, thereby realizing the combined illumination of the LED work lamp 10.

In the present embodiment, as shown in fig. 3 and 4, the base 100 is provided with an auxiliary support plate 140, the length of the auxiliary support plate 140 is greater than the length of the heat sink 130, the light source assembly 200 includes a storage battery 240 (as shown in fig. 2), the storage battery 240 is mounted on the auxiliary support plate 140, and the storage battery 240 is electrically connected to the LED lighting board 210. Because the length of the auxiliary support plate 140 is greater than that of the heat sink 130, a certain distance is left between the battery 240 and the heat sink 130 after the battery 240 is installed, so that the battery 240 does not shield the heat sink 130, i.e., the heat sink 130 is not affected in heat dissipation. Furthermore, the auxiliary plate 140 can be used as a fixing part when the two bases 100 are connected, that is, the connecting frame 400 connects the auxiliary plates 140 of the two bases 100 when combined.

During the use, light source subassembly 200 is installed in proper order on installation flat plate 110, and battery 240 installs on supplementary extension board 140, and battery 240 supplies power for LED cloth lamp board 210 is luminous, and light shines the place ahead through light-passing board 220. In the using process, the LED light distribution plate 210 generates heat, and as the LED light distribution plate 210 is attached to the mounting flat plate 110, the heat generated by the LED light distribution plate 210 is transferred to the mounting flat plate 110 and the heat dissipation fins 130, the heat dissipation area of the heat dissipation fins 130 is increased, and air can circulate in the heat dissipation gaps 131, so that the heat on the heat dissipation fins 130 can be quickly carried by outside air, and the LED light distribution plate 210 cannot be damaged due to overhigh working temperature;

when the lighting device is used, workers can select different powers for lighting according to the requirements of different lighting occasions, and can combine the base 100 and the light source component 200 thereon. Specifically, when the demand for the illumination power is low in the illumination occasion, the worker may use the LED work lamp 10 composed of a single base 100; when the lighting occasion has a high demand for lighting power, the worker can combine two or more bases 100 through the link frame 400. When combined, the connecting frame 400 connects the auxiliary support plates 140 between two adjacent bases 100; when combined, a plurality of bases 100 may share one fixing bracket 300, and at this time, the fixing bracket 300 may be connected to the connecting bracket 400 by the fastening assembly 320 (as shown in fig. 7).

It should be noted that, a manner of changing the light emitting intensity (illumination power) of the LED light distribution plate 210 by changing the supply current of the LED light distribution plate 210 is not adopted, because the heat generated by the LED light distribution plate 210 is obviously increased due to the increase of the supply current, the operating temperature of the LED light distribution plate 210 is rapidly increased, and the LED light distribution plate 210 is easily burned out. Moreover, the obvious change of the power supply current may damage the fine connection circuit inside the LED lighting arrangement board 210, thereby seriously reducing the service life of the LED lighting arrangement board 210. Therefore, the LED work lamp 10 of the present invention adopts a combination method to change the lighting power.

As shown in fig. 8 and 9, the LED working lamp 10 of the present invention can obtain different structures through different combination modes, for example, the LED working lamp 10 shown in fig. 8 is composed of 2 bases 100, and each base 100 has 3 light source assemblies 200. For another example, the LED working lamp 10 shown in fig. 9 is also composed of 2 bases 100, and each base 100 has 4 light source assemblies 200. Of course, the above is one of the structures of the LED working lamp 10 of the present invention after combination, and the LED working lamp 10 may be combined by different arrangements of other plural bases 100.

It should be further noted that, in practice, the LED working lamp 10 of the present invention can be provided with illumination combinations from two aspects, on one hand, by changing the number of the light source assemblies 200 disposed on one base 100, for example, by disposing four mounting plates 110 (as shown in fig. 2) on one

base

100, 1 to 4 light source assemblies 200 can be freely mounted on the base 100; on the other hand, by combining a plurality of bases 100, for example, as shown in fig. 4 and 5, two bases 100 are combined together by the connecting frame 400, the number of light source assemblies 200 will be increased or decreased by multiple times. Through the combination of the two modes, the LED working lamp 10 can meet the requirements of different lighting occasions, for example, when the range of required illumination is larger and the requirement is brighter, the number of the light source assemblies 200 or the bases 100 can be increased, so that the lighting power of the LED working lamp 10 is increased; conversely, the number of the light source assemblies 200 or the bases 100 can be reduced appropriately, so as to reduce the illumination power of the LED working lamp 10, and achieve energy saving and power saving.

In this embodiment, as shown in fig. 5 and fig. 6, the LED lighting board 210 is provided with a plurality of LED lamp beads 211, and one side of the light-transmitting plate 220 is provided with a lens 221 corresponding to the LED lamp beads 211. Further, in order to improve the light efficiency utilization rate of the LED lamp bead 211 and improve the defects of uneven light intensity distribution and the like, the LED lamp bead 211 needs to be subjected to secondary optical processing. For this reason, the present embodiment is particularly provided with a lens 221 corresponding to the LED lamp bead 211.

Specifically, as shown in fig. 10, the lens 221 is provided with a receiving groove 222 and a light emitting surface 223, an edge of the receiving groove 222 expands outward and extends toward the light emitting surface 223 to form a conical surface 224 (the conical surface 224 is in a horn shape), the conical surface 224 is provided with a reflective coating, the LED lamp bead 211 is received in the receiving groove 222, and the receiving groove 222 is provided with a vertical light transmitting surface 222a and a spherical light transmitting surface 222 b.

After the light-transmitting plate 220 is covered on the LED light distribution plate 210, the LED lamp beads 211 are just located in the accommodating groove 222 of the lens 221, most of the light emitted by the LED lamp beads 211 is collected (the convex lens has the function of collecting light) after passing through the spherical light-transmitting surface 222b, and because the focal length of the spherical light-transmitting surface 222b is short, the light is further scattered in the lens 221 after being collected, and then is emitted from the light-emitting surface 223 to be released to the outside; another part of the light passes through the vertical light-transmitting surface 222a to be refracted for the first time, and the refracted light is emitted onto the tapered surface 224. due to the reflective coating on the tapered surface 224, the light is refracted or reflected again, and finally emitted from the light-emitting surface 223 to be released to the outside. It is thus clear that the light that LED lamp pearl 211 distributed can make the light that reachs out the plain noodles 223 more even through refraction or reflection many times to improve LED lamp pearl 211's light efficiency utilization ratio, improve defects such as illumination intensity distribution is inhomogeneous.

In another embodiment, as shown in fig. 11, except that a plurality of LED lamp beads 211 are also disposed on the LED light board 210, a reflective cup 225 corresponding to the LED lamp beads 211 is disposed on one side of the light-transmitting plate 220, and the LED lamp beads 211 are located at the bottom of the reflective cup 225. After the light reflecting cup 225 is adopted, light emitted by the LED lamp beads 211 can be further irradiated through the gathering of the light reflecting cup 225.

In this embodiment, the light-transmitting plate 220 is provided with a stepped groove 226 (as shown in fig. 10), the protective outer frame 230 is provided with a pressing section 232 and an extending section 233 (as shown in fig. 12), the pressing section 232 of the protective outer frame 230 is pressed on the stepped groove 226, and the extending section 233 of the protective outer frame 230 is located outside the mounting flat plate 110, that is, the mounting flat plate 110 is wrapped in the protective outer frame 230. A seal ring 250 is provided between the transparent plate 220 and the mounting plate 110 (as shown in fig. 12), and a seal groove 227 for accommodating the seal ring 250 is formed at the edge of the transparent plate 220 (as shown in fig. 10). The section 232 and the cooperation of ladder groove 226 are held to the pressure of protection frame 230 for press when protection frame 230 and hold difficult emergence after the light-passing board 220 edge and rock, moreover, along with the increase of the section 232 pressure is held to the pressure, the pressure that sealing washer 250 was held to the pressure of light-passing board 220 edge pressure also can increase, thereby eliminate the clearance between light-passing board 220 and the installation flat plate 110, play waterproof dirt-proof effect.

In the present embodiment, as shown in fig. 13, a threading through hole 111 is formed on the mounting plate 110, a cable waterproof connector (also called glan head) is disposed at the threading through hole 111, and the electric wire of the storage battery 240 passes through the cable waterproof connector and is electrically connected to the LED lighting board 210. The wire is connected by penetrating the waterproof joint of the cable, so that rainwater can be prevented from contacting the exposed joint of the wire connection part, and the short circuit of the wire is caused. Moreover, since the light-transmitting plate 220 and the mounting plate 110 are strongly sealed, a good waterproof and dustproof effect can be achieved, but a sealed space is formed in the light-transmitting plate 220 due to the strong sealing property. With the use of the LED lighting board 210, the LED lighting board 210 generates heat, so that the air pressure in the light-transmitting plate 220 is increased; after the use is stopped, the temperature and the air pressure in the transparent plate 220 decrease. Like this, LED lamp pearl 211's operating pressure appears obviously undulantly, leads to LED lamp pearl 211 to damage easily, has reduced its life. In order to solve the above problem, in this embodiment, the mounting plate 110 is provided with an exhaust hole 112, and an explosion-proof relief valve is mounted at the exhaust hole 112. Through the threshold value of setting for explosion-proof relief valve for after the atmospheric pressure in the light-passing board 220 rose certain degree, atmospheric pressure just can let out to the external world from explosion-proof relief valve in it, thereby makes LED lamp pearl 211's working air pressure relatively stable, extension LED lamp pearl 211's working life.

In the present embodiment, as shown in fig. 14, the fastening assembly 320 includes: the limiting bolt 321 penetrates through the supporting arm 310 and the main body supporting plate 120 of the fixed support 300, the fixed gear disc 322 is installed on the main body supporting plate 120, the movable gear disc 323 is installed on the supporting arm 310, and the fixed gear disc 322 and the movable gear disc 323 are meshed with each other. When the base 100 and the fixed bracket 300 are stable, namely the base 100 cannot rotate relative to the fixed bracket 300, the staff can tighten the limiting bolt 321 to a proper degree, so that a proper pressure is provided between the fixed gear disc 322 and the movable gear disc 323, and at the moment, the gravity of the base 100 cannot overcome the pressure between the fixed gear disc 322 and the movable gear disc 323 in a free state. When the irradiation angle needs to be adjusted, the worker pulls the base 100, so that the deflection force of the base 100 is enough to overcome the pressure between the fixed toothed disc 322 and the movable toothed disc 323, at this time, the supporting arm 310 of the fixed bracket 300 is slightly deformed, so that the fixed toothed disc 322 and the movable toothed disc 323 can rotate relatively, and thus, the base 100 can rotate a certain angle relative to the fixed bracket 300. When a plurality of bases 100 are combined, the fixed gear plate 322 may be disposed on the connecting frame 400 (as shown in fig. 7), and the principle thereof is the same as that described above.

In one embodiment, as shown in fig. 15, a rain cover 150 is disposed on the base 100, the rain cover 150 is fixed on the base 100, and the rain cover 150 includes a top plate 151 and a side plate 152. When the LED work light 10 is disposed outdoors, the rain shade 150 can provide rain-shielding and sun-shading functions for the light source assembly 200, thereby reducing the corrosion damage of rainwater to the light source assembly 200.

To sum up, the utility model discloses a LED work light 10 makes its simple structure and has good heat-sinking capability, can conveniently make up simultaneously to satisfy the demand of different illumination occasions to different power illuminations.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention.
