[0005] The base of the above-mentioned explosion-proof fluorescent purification lamp forms a relatively closed cavity, which accumulates the heat of the lamp tube on the lamp and is difficult to dissipate, which also affects the life of electrical components such as lamp tubes and ballasts.
The thickness of this kind of lamp is very thick, the volume and weight are large; and the purification effect is not good. Since the bottom wall is a plane with a relatively large area, there are inevitably gaps at the edge when it is connected to the ceiling. Once dust accumulates, it will seriously affect chemical, pharmaceutical, Dust protection in food and other industries
[0006] In addition, common lamps are more suitable for T12 and T10 fluorescent tubes, which are bulky and have insufficient illumination. Usually, the lumen per watt is less than 701m. A set of double-tube 40w explosion-proof lamps that are routinely used in a working environment with a height of 2.6m has an actual measured average illuminance. 130-140, 300LUX, which is significantly different from the average illuminance requirement of the general pharmaceutical industry above 300LUX, so the lamp density can only be set very high

no. 1 example
[0036] Such as Figure 4 , the bottom wall 33 is a hollow frame on the plane, and the middle part of the top wall 31 is recessed toward the direction of the bottom wall 33 to form a concave platform 311 , and the lamp pin 4 is arranged on the concave platform 311 through a lamp holder. There is a gap between the concave platform 311 and the side wall 32 to form a heat dissipation channel, which significantly improves the heat dissipation of the entire lamp. For integral molding, convenient installation and aesthetics, the bottom of the recessed platform 311 is usually flat and flush with the bottom wall 33 .
[0037] The contact area between the bottom wall 33 and the ceiling is very small to prevent gaps and dust accumulation.
no. 2 example
[0039] Such as Figure 5 The sides of the four side walls 32 of the base 3 away from the top wall 31 are respectively inclined towards the direction away from the concave table 311, and the width of the bottom wall 33 shrinks to form the top of the side wall 32, that is, the bottom wall 33 is directly omitted . Only the top of the side wall 32 is in linear contact with the ceiling, the area is very small, and there are very few gaps, so it is difficult to accumulate dust.
[0040] The angle R between the side wall 32 and the top wall 31 is preferably less than or equal to 135 degrees, so that the strength of the component is better and the manufacturing material is relatively saved. In this embodiment, there is still a gap between the concave platform 311 and the side wall 32 to form a heat dissipation channel.
no. 3 example
[0042] Such as Image 6 , the other parts of the base of this embodiment are the same as those of the second embodiment, and a reinforcing rib 321 is provided at the bottom of the side wall 32. The presence of the reinforcing rib 321 changes the stress on the bottom of the side wall 32, greatly increasing the deformation strength of the base, Reduce the possibility of deformation.
[0043] The above three base embodiments can all be formed by pressing plates, and the production is very simple.
[0044] Such as Figure 7 1. At least one flexible connecting piece 7 is fixedly arranged on the lamp cover 2 , and the flexible connecting piece 7 is connected with the lamp cover 1 . The flexible connector 7 is a metal chain or a nylon rope or the like. When overhauling the lamps, the lamp cover can be directly hung under the lamps without manual lowering, so only one worker can complete the inspection, which greatly improves the maintenance convenience and work efficiency.

Abstract
The invention relates to a light fitting structure and especially relates to an explosion proof fluorescent purification light fitting structure. An ultrathin explosion proof fluorescent purification light fitting structure comprises a lampshade, a lamp cover, a pedestal and a lamp leg arranged on the pedestal through a lamp bracket, which are detachably connected together in sequence, and at least one lighting tube installed on the lamp leg; the pedestal comprises a top wall connected with the lamp cover, a bottom wall connected with the ceiling and four side walls connected with the top wall with the bottom wall, the bottom wall is a hollow frame on the plane, the middle part of the top wall depresses towards the direction of the bottom wall to form a depression, a segment of gap exists between the depression and the side walls, and the lamp leg is arranged on the depression through the lamp bracket. The ultrathin explosion proof fluorescent purification light fitting structure provided by the invention can be used for greatly improving the radiating conditions, improving the purification effect, reducing the thickness of the light fitting, saving the material cost and greatly improving the illumination of unit light fitting, and the ultrathin explosion proof fluorescent purification light fitting structure is especially suitable for T5 explosion proof fluorescent lighting tubes with large brightness and small diameters.
Description
technical field [0001] The invention relates to a lamp structure, in particular to an explosion-proof fluorescent purification lamp structure. Background technique [0002] Explosion-proof fluorescent purification lamps installed with fluorescent tubes are widely used in chemical industry, medicine, biotechnology, electronics, food, military industry, petroleum and other fields that require explosion-proof and dust-proof purification lighting. The basic structure of explosion-proof fluorescent purification lamps is as follows: figure 1 , including a light-transmitting lampshade 1 , a lamp cover 2 and a base 3 . [0003] There are lamp holders (omitted in the figure) on both sides of the base 3, and the lamp pins 4 are arranged on the lamp holders. After removing lampshade 1 and lamp cover 2, if figure 2 As shown, a plurality of fluorescent lamp tubes 5 are inserted on the lamp pins 4 , and a reflector (omitted in the figure) is arranged between the base 3 and the lamp tu...
