Description

Technical Field

[0001] The utility model relates to the technical field of floodlights, in particular to a heat dissipation type floodlight. Background Art

[0002] A floodlight is a lamp with a higher illumination on the designated illuminated surface than the surrounding environment. Usually, it can be aimed in any direction and has a structure that is not affected by climatic conditions. A floodlight consists of three parts: optical components, mechanical components, and electrical components. The optical components are mainly reflectors and light-limiting shading grids. The mechanical components are mainly the casing, as well as a focusing mechanism for fixing and adjusting the position of the light source, a bracket and base for fixing the lamp, and parts with angle indicators for adjusting the projection direction of the lamp beam. It is mainly used in large-scale work sites, mines, building outlines, stadiums, overpasses, monuments, parks, and flower beds. When working at high power, floodlights will generate a lot of heat, so they need to have a certain heat dissipation function. Most existing floodlights dissipate heat by setting heat dissipation fins on the outer side of the casing. This heat dissipation method has low heat dissipation efficiency, and the heat dissipation fins exposed to the outside are prone to deformation, which leads to a reduction in the overall intensity of the floodlight. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 4 As shown, the utility model is a heat dissipation type floodlight, comprising a rear cover 3, an LED lamp core 10 is installed in the rear cover 3, a front guard plate 1 is fixedly provided at the front end of the rear cover 3, a light-transmitting plate 2 is fixedly installed on the front guard plate 1, and the surfaces of the light-transmitting plate 2 and the front guard plate 1 are flush;

[0026] The lower end of the rear cover 3 is provided with a plurality of terminal blocks 5 for connecting wires; side connecting seats 6 are fixedly provided on both side walls of the rear cover 3, and support frames 8 are installed on the side connecting seats 6 through locking bolts 7.

[0027] A plurality of heat dissipation ribs 31 are evenly arranged on one side of the rear cover 3 away from the front guard plate 1 .

[0028] Specifically, the rear cover 3 and the front guard plate 1 are an integrated structure, so that the outer shell of the floodlight is an integrated structure, thereby increasing the overall strength of the outer shell.

[0029] Specifically, the setting of the heat dissipation ribs 31 can effectively dissipate heat for the LED lamp core 10 installed at the bottom of the rear cover body 3, thereby effectively reducing the temperature inside the rear cover body 3, avoiding the influence of high temperature on the operation of the LED lamp core 10, and improving the service life of the floodlight.

[0030] Furthermore, a plurality of heat dissipation grooves 33 are provided on the heat dissipation rib 31. The provision of the heat dissipation grooves 33 increases the contact area between the heat dissipation rib 31 and the outside world, thereby further improving the heat dissipation effect of the floodlight.

[0031] Specifically, a wave pattern is formed between the heat dissipation slots 33 and the heat dissipation ribs 31, which is conducive to convection heat dissipation, so that the entire lamp dissipates heat faster and the product is more stable.

[0032] Different from the traditional ribs with a straight structure, the heat dissipation ribs of the present application themselves have a wavy design, which improves the heat dissipation performance and overall strength of the entire floodlight.

[0033] Furthermore, the heat dissipation ribs 31 not only dissipate heat for the floodlight, but also improve the overall strength of the entire rear cover 3 and the entire floodlight.

[0034] The rear cover 3 is provided with a plurality of mounting posts 32 for mounting the LED lamp wicks 10 , and the mounting posts 32 are connected to the heat dissipation ribs 31 .

[0035] Specifically, the provision of the mounting post 32 can strengthen the installation of the LED lamp core 10 and improve the stability of the bolt installation through the mounting post 32. In addition, by matching the mounting post 32 with the heat dissipation rib 31, the overall strength of the floodlight can be improved.

[0036] A wiring seat 4 is fixedly provided at the lower end of the rear cover 3 , and the wiring head 5 is installed at the lower end of the wiring seat 4 .

[0037] Specifically, by setting up the wiring base 4, sufficient space is reserved for connecting the wires of the floodlight, thereby facilitating quick wiring of the floodlight, and a section of wire can be reserved in the wiring base 4, thereby facilitating increasing the installation range of the floodlight.

[0038] A light guide seat 9 is installed on one side of the front guard plate 1 close to the rear cover 3, and the light guide seat 9 is a funnel-shaped structure.

[0039] Specifically, the arrangement of the light guide seat 9 guides and focuses the light emitted by the LED lamp core 10, thereby effectively ensuring that the floodlight can project the light in a concentrated manner and improving the projection effect of the floodlight.

[0040] The support frame 8 includes side connecting plates 81 installed on the side connecting seat 6, and a diagonal support plate 82 is fixedly connected between two groups of side connecting plates 81.

[0041] Specifically, the diagonal support plate 82 can be arranged to be used for installing the floodlight on one hand, and can be used for supporting the floodlight on the other hand, so that the floodlight can be installed in different directions to adapt to different working modes.

[0042] Preferably, the diagonal support plate 82 is designed with a 45° bevel, which is more convenient for installation and helps save installation costs.

[0043] A central hole 83 is provided at the center of the diagonal support plate 82 , and a plurality of waist holes 84 are provided on the diagonal support plate 82 .

[0044] Specifically, the center hole 83 can be used to install the floodlight. In addition, multiple sets of waist holes 84 facilitate the installation of the floodlight in different positions, avoiding deviations in the installation of the floodlight due to problems with the accuracy of the installation equipment.

[0045] The working principle of the present invention is as follows: the wire is inserted into the terminal block 4 through the terminal block 4, and sufficient space is reserved for the wire connection of the floodlight by setting the terminal block 4, so as to facilitate the quick wiring of the floodlight, and a section of wire can be reserved in the terminal block 4, which is convenient for increasing the installation range of the floodlight, and the floodlight is installed using the diagonal support plate 82. The setting of the diagonal support plate 82 can be used to install the floodlight on the one hand, and can be used to support the floodlight on the other hand, so that the floodlight can be installed in different directions to adapt to different working modes. When the floodlight is installed, the LED wick 10 works to emit light, and the light emitted by the LED wick 10 is guided and focused by the light guide seat 9, thereby effectively ensuring that the floodlight can concentrate the light and improve the projection effect of the floodlight.

[0046] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
