Embodiment 1

[0028] a light fixture, see figure 1 , including a lamp housing 11, a groove 12 is provided at any position on the outer wall of the lamp housing 11.

[0029] The bottom of the groove 12 is formed with four first threaded through holes 13 (not all marked in the figure), and these four first threaded through holes 13 are symmetrically distributed on the two central axes of the groove 12 Above, each first threaded through hole 13 is respectively inserted with a first screw 18 ( Figure 4 shown in ) as a balance valve for balancing the internal and external pressures of the lamp housing 11 .

[0030] Four second threaded blind holes 14 (not all of them are marked in the figure) are also provided on the side wall of the groove 12 .

[0031] The inside of the groove 12 is laid with a multi-layer non-woven fabric 15, see figure 2 , the shape of the non-woven fabric 15 is the same as the shape of the inner edge of the groove 12, and the outer edge of the non-woven fabric 15 is cl...

Embodiment 2

[0036] This embodiment takes the floodlight as an example and makes further improvements on the basis of Embodiment 1, so that it can not only maintain the advantages of waterproof and dustproof, accelerate heat dissipation and balance internal and external pressure, but also have the ability to adjust the irradiation angle of the floodlight Features.

[0037] The floodlights, see Figure 5 , including a lamp housing 21 and a lamp bracket 22 . The two side walls of the lamp housing 21 are respectively formed with a second groove 23 that is the same as the groove 12 in Embodiment 1, see Figure 6 , each second groove 23 is provided with an annular guide groove 24 , and the circumference of each guide groove 24 is provided with four third threaded blind holes 25 .

[0038] Each groove is also equipped with a second round top cover 26 (including the second threaded through hole 17) identical to the round top cover 16 in Embodiment 1, see Figure 7 . Each second round top cove...

Abstract

Disclosed is a lamp. The lamp comprises a lamp shell, wherein at least one groove is formed in the outer wall of the lamp shell, a plurality of through holes are formed in the bottom of each groove, a film is further laid inside each groove, and a top cover is arranged on each groove and used for covering the groove. According to the invention, heat generated by the lamp due to irradiation for a long time can be dissipated in time, the internal air pressure and the external air pressure are balanced, and the service life of components is prolonged. Meanwhile, water mist and dust located outside the lamp are prevented from entering the lamp, and the lamp has quite high practical value. In addition, the top covers of the lamp have the function of adjustment of the illumination angle.

Description

technical field [0001] The invention relates to a lamp, in particular to a floodlight. Background technique [0002] Existing lamps used for outdoor lighting often achieve waterproof and dustproof effects by adopting a sealed shell, but a completely sealed shell will affect the air circulation inside and outside the lamp. Especially in actual use, if the lamp is irradiated for a long time, a large amount of heat will be generated inside the lamp housing. The completely sealed housing cannot dissipate heat from the lamp in time. When the heat is concentrated to a certain amount, it will affect the use of the lamp and the life of components. . [0003] Floodlights are generally suitable for large-area projection lighting in public places such as stadiums, industrial buildings, city squares, stations, ports, ships, and large-scale construction. The longer the time, the more prone to heat dissipation difficulties. Contents of the invention [0004] The technical problem to ...
