Embodiment Construction
[0023] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0024] figure 1 It is a structural schematic diagram of a lamp in an embodiment. The transparent part device of the lamp comprises a back shell 100, a front cover 200 connected with the back cover 100, a reflector 300, a transparent part 400, a dustproof ring 500 and a protective cover which are sequentially arranged between the back cover 100 and the front cover 200 and abut against them. Glass sheet 600. A light source is provided in the rear shell 100, and the reflector 300 is adapted to be installed in the rear shell 100. The transparent member 400, the dust-proof ring 500 and the protective glass sheet 600 are installed in the front cover 200, and the reflector 300 reflects and concentrates the light from the light source. It is emitted through the transparent member 400 and the protective glass sheet 600 . The protectiv...

The invention relates to a lamp which comprises a front cover, a rear casing connected with the front cover, a reflector arranged in the rear casing, a transparent member arranged in the front cover and a protecting glass piece, wherein the protecting glass piece is arranged between the front cover and the transparent member and is used for carrying out isolating protection on the transparent member; and the protecting glass piece, the transparent member and the reflector are sequentially abutted. According to the lamp disclosed by the invention, the protecting glass piece for preventing polished damage to the transparent member caused by hard objects is arranged between the transparent member and the front cover of the lamp, thereby the impact strength of the lamp can be ensured, the light emitting of the lamp is influenced because the surface of the transparent member is worn can be effectively prevented, the safety and performances of the lamp are greatly ensured, the problem of material selection in the design of the transparent member is solved, further the cost is reduced and expenses are saved. Meanwhile, a dustproof ring which can be used for carrying out sealed dust prevention and preventing dust from entering a space between the protecting glass piece and the transparent member is arranged between the protecting glass piece and the transparent member, so that the influence on the light emitting of the lamp caused by the dust can be further reduced.
Description
【Technical field】 [0001] The invention relates to a lighting appliance, in particular to a lamp. 【Background technique】 [0002] In lighting fixtures, especially in flameproof explosion-proof lighting fixtures, the transparent part is a part of the shell of the lamp, which requires a certain strength to ensure that the lamp will not be damaged when it is subjected to a strong impact. [0003] Traditionally, in order to ensure that the transparent parts have a certain strength, polycarbonate (Polycarbonate abbreviated as PC) is usually used as the material of the transparent parts. PC is commonly known as bulletproof glue and has strong impact resistance. However, PC, like other plastic materials, is easily scratched and damaged when it rubs against hard objects, which affects the light output of the lamp and reduces the performance of the lamp. Simultaneously, the problem of material selection for transparent parts has been increased, and the cost has been increased. 【Con...
