Description

Technical Field

[0001] The utility model relates to the technical field of lighting lamps, and in particular to an LED floodlight which is advantageous for heat dissipation. Background Art

[0002] Floodlights are widely used in various lighting scenarios, such as lighting of buildings, landscapes, stadiums, stages, and squares.

[0003] Existing LED floodlights generally have the following two problems: first, the battery of the floodlight is integrated inside the floodlight. As a result, the heat generated by the LED lamp beads and the battery will be superimposed inside the lamp body, causing the lamp body to overheat easily; second, although the existing LED floodlights have a bracket through which the LED floodlight can be placed on the ground for use, this bracket is only suitable for use on hard and flat surfaces, such as cement pavement, tile pavement, marble pavement, etc. When used for landscape lighting in parks, ponds, etc., the placement location is often full of mud and prone to water accumulation. In this case, this bracket is no longer suitable, and an additional bracket is often required to install the floodlight. Utility Model Content

[0018] The technical solution of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0019] It should be noted that all directional indications in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0020] Reference Figures 1 to 4The utility model proposes an LED floodlight, including a bracket 1, a power supply component 2, a lamp housing 3 installed on the bracket 1, a light source arranged in the lamp housing 3, and a heat sink arranged on the surface of the lamp housing 3. A light-transmitting plate 6 is provided at the front of the lamp housing 3. The light source is electrically connected to the power supply component 2. The power supply component 2 is located outside the lamp housing 3 and connected to the lamp housing 3.

[0021] Preferably, the above-mentioned light source includes a lamp board 7 arranged in the lamp housing 3 and LED lamp beads arranged on the lamp board 7, and the heat sink includes a plurality of heat dissipation fins 31 located on the rear surface of the lamp housing 3. Each heat dissipation fin 31 is arranged in the up and down direction, and a heat dissipation space is left between adjacent heat dissipation fins 31. The power supply component 2 includes a power supply box and a power supply arranged in the power supply box. A support column 32 is also provided on the rear surface of the lamp housing 3, and the power supply box is screwed to the support column 32. The above-mentioned power supply is preferably a battery, among which a storage battery is the best. In addition, the floodlight can also be plug-in, and accordingly, the power supply component 2 is a power adapter.

[0022] Reference Figure 1 and Figure 3 A gap is formed between the power supply box and the rear surface of the lamp housing 3. The heat dissipating fins 31 are located in this gap. All of the heat dissipating fins are made of metal. The lamp housing 3 can be entirely metal, or it can be mostly plastic with a small portion of metal. The heat dissipating fins 31 are integrally formed with or closely attached to the metal portion of the lamp housing 3. The lamp board 7, which houses the LEDs, is in close contact with the metal portion of the lamp housing 3 to enhance heat dissipation.

[0023] The LED floodlight installs the power supply component 2 outside the lamp housing 3 to facilitate heat dissipation. At the same time, when the power supply component 2 is battery-powered, the shape and size of the battery are less restricted by space, and mature battery products on the market can be directly purchased, which is conducive to reducing costs.

[0024] Furthermore, at least one insertion rod 4 is detachably mounted on the bracket 1, the lower end of the insertion rod 4 is a pointed end, the upper portion of the insertion rod 4 is provided with a first connecting structure, and the bracket 1 is provided with a second connecting structure that can be detachably connected to the first connecting structure.

[0025] In a preferred embodiment of the present invention, the bracket 1 includes two transverse bars 11 arranged along the front-to-back direction, a longitudinal bar 12 arranged along the left-to-right direction, and a vertical bar 13 fixed to the longitudinal bar 12. The ends of the longitudinal bar 12 are fixedly connected to the two transverse bars 11. The transverse bars 11 are hollow bars. There are two insertion rods 4, which are accommodated in a one-to-one correspondence within the two transverse bars 11. The ends of the transverse bars 11 are detachably mounted with end caps 5. The end caps 5 are screwed or interference-fitted with the transverse bars 11. There are two vertical bars 13, and the lamp housing 3 is mounted between the upper ends of the two vertical bars 13. The first connecting structure is a screw 41 provided on the upper portion of the insertion rod 4, and the second connecting structure is a vertical screw hole 121 provided on the longitudinal bar 12 and adapted to the screw 41.

[0026] With this design, the LED floodlight can adapt to a variety of different working environments. For example, when it is placed on a hardened ground, it can be used Figure 1 The installation method is as follows: the two insertion rods 4 are respectively housed in the two hollow cross bars 11. The two cross bars 11 act as supporting feet and can be placed directly on the ground. When the installation location is in the soil of a park, wetland or other landscape or a place where water easily accumulates, the end cover 5 can be opened, the two insertion rods 4 can be taken out, and then the two insertion rods 4 can be respectively installed in the two vertical screw holes 121 of the longitudinal bar 12. Finally, the two insertion rods 4 can be inserted into the soil to complete the installation. The state at this time is as follows: Figure 4 shown.

[0027] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention.
