Embodiment 1

[0035] Embodiment one: if figure 1 , 2 , 3, 4, and 5, the cover body 10 is in the shape of an inverted bowl, and the cover body 10 includes a bowl bottom 110 and a bowl wall 120 extending obliquely downward from the edge of the bowl bottom 110, the bowl wall A plurality of through holes 132 are opened on the surface of the bowl wall 120 , and the through holes 132 start from the edge of the blind hole and extend downward to the edge of the bowl wall 120 . The angle between the obliquely extending bowl wall 120 and the bowl bottom 110 is greater than 90 degrees.

[0036] Such as figure 1As shown, the plurality of through-holes 132 opened on the above-mentioned cover body 10 are elongated, and the elongated through-holes 132 are divided into multiple groups. A first preset spacing, a second preset spacing is left between the plurality of elongated through holes in each group along the circumference of the side wall surface, and the first preset spacing is greater than the sec...

Embodiment 2

[0041] Embodiment two: if Figures 8 to 11 as shown, Figure 8 Among them, the large end surface of the housing 20 with the largest caliber protrudes upwards around its circumferential direction with a plurality of cooling bars 221, and each cooling bar 221 includes a plurality of fin-shaped cooling ribs 244, and there are gaps between each fin-shaped cooling ribs 244. predetermined gap; the cover 10 fixedly connected to the end face of the housing 20 is in the shape of a cap, such as Figure 9 , 10 , 11, the cover body 10 includes a hat top 920, and a hat brim 130 extending vertically downward from the edge of the hat top 920, and the edge of the hat brim 130 abuts against the heat dissipation bar 221. At the top, the cover body 10 is fixedly connected with the large end surface of the housing 20 through fasteners, that is, is fixedly connected with the cup rim 220 through fasteners. A first threaded hole 134 is provided on the brim part 130, and the threaded hole 134 is u...

Abstract

The invention relates to an LED street lamp which comprises a shell, a cover body and an explosion-proof piece, wherein the shell is in a rotary table type hollow structure; the outer surface of the shell is sleeved with a transparent piece; the inner surface of the shell is provided with a heat radiating structure; a sealing cavity is formed between the transparent piece and the outer surface ofthe shell and is used for containing a luminous light source; the cover body is of an inverted bowl shape and is provided with a plurality of through holes; the through holes extend downwards to the edge position of the wall of the bowl; the explosion-proof piece is contained in a containing cavity; a gap is reserved between the explosion-proof piece and the end surface of the shell; an explosion-proof cavity is formed on the explosion-proof piece and used for accommodating an electrical equipment element used for driving the luminous light source to emit light; the lower surface of a lower cover of the explosion-proof piece is provided with a power terminal of the street lamp; a power line of a circuit board in the explosion-proof cavity is led out through an explosion-proof connector lug; then the power line is led into a street lamp column by a connector lug of the street lamp column at the lower part of the shell; and consequently the LED street lamp is applied to a street lamp conveniently.

Description

【Technical field】 [0001] The invention relates to a lighting device, in particular to an LED street lamp. 【Background technique】 [0002] With the rapid development of science and technology, lighting fixtures are used more and more widely in production, storage and rescue, and there are more and more varieties. Since lighting fixtures usually use metal halide lamps or fluorescent lamps as light sources, electric sparks or hot surfaces will inevitably be generated during work. Once they meet explosive gas, dust or their mixture at the production or rescue site, they will be lead to explosion accidents. Therefore, how to prevent the occurrence of explosion accidents of lighting fixtures has become a very important issue in dangerous places where explosive gas, dust or their mixtures exist. Existing LED street lamps achieve the purpose of explosion protection by limiting the temperature of the surface of the housing where arcs and sparks generated inside the lamps come into ...
