Abstract
The utility model discloses an anti-explosion LED street lamp and anti-explosion electric appliance equipment. The anti-explosion LED street lamp is composed of a shell, LED light sources and a light reflecting cover. The front end in the shell is provided with a circuit board seat, the tail end in the shell is provided with a wire penetrating cavity, and the wall of the tail end is provided with a wire inlet. The upper portion of the circuit board seat is sequentially provided with a circuit board and the light reflecting cover. The LED light sources are evenly distributed on the circuit board, and the light reflecting cover is an array type light reflecting cover used in cooperation with the LED light sources. The upper portion of the circuit board seat and the upper portion of the light reflecting cover are provided with transparent covers, the transparent covers are fixed to the shell through frame pressing pieces, and the back of the shell is evenly provided with heat dissipating ribs. The anti-explosion LED street lamp is simple in structure, low in manufacturing cost, low in processing cost and convenient to demount and mount, the LED light sources are adopted, energy consumption is low, the heat dissipating amount is small, fatal damage to internal elements is avoided, internal heat can be effectively dissipated out, the service life is long, and the maintaining rate is low.
Description
Technical field
The utility model relates to explosion-proof electric equipment, relates in particular to the explosion-proof street lamp of LED.
Background technology
In the inflammable and explosive environment such as petrochemical industry, pharmacy, chemical industry, outdoor lighting also needs to use the street lamp with explosion-proof performance, the explosion-proof street lamp of tradition, the bulb that light source selects screw socket to connect, bulb power consumption is large, service life is short, dispel the heat also larger, and because housing is Explosion-proof Design, housing does not have louvre and gap, thereby the heat accumulation distributing is inner at lamp housing, can not distribute fast and effectively, and then make inner component element long period under high temperature under state, internal component has shortened service life greatly, has increased maintenance work and expense.
Utility model content
The utility model is for the deficiency existing in background technology, and the explosion-proof street lamp of the LED providing.
The explosion-proof street lamp of LED of the present utility model, to be formed by housing, LED light source and reflection shield, the front end of its shell inside is that circuit panel seat, tail end are threading chamber, and be provided with entrance hole on tail end wall, the top of circuit panel seat is equipped with circuit board and reflection shield successively, uniform LED light source on described circuit board, reflection shield is the array being used in conjunction with LED light source, the top of circuit panel seat and reflection shield is provided with translucent cover, described translucent cover is fixed on housing by frame casting die, the back of described housing uniform radiating ribs.
As further improvement of the utility model, described screw rod on the housing of entrance hole outer end is connecting mounting sleeve.
As further improvement of the utility model, described mounting sleeve is provided with plural radially Limit screw.
As further improvement of the utility model, described LED light source is connected with the inlet-wire parallel on circuit board.
The explosion-proof street lamp of LED of the present utility model, simple in structure, processing cost is low, remove and install conveniently, adopt LED light source, consume energy low, heat dissipation capacity is little, the damage of having avoided internal high temperature to cause components and parts, the heat that can effectively inner light source be produced distributes fast, has extended service life, reduces maintenance rate and maintenance cost.
Accompanying drawing explanation
Fig. 1 is decomposition texture schematic diagram of the present utility model;
Fig. 2 is back structures schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1 and 2 pairs of explosion-proof street lamps of LED of the present utility model of accompanying drawing, be described further.
The explosion-proof street lamp of LED of the present utility model, to be formed by housing 1, LED light source 2 and reflection shield 3, the front end of its housing 1 inside is that circuit panel seat 4, tail end are threading chamber 5, and on tail end wall, be provided with entrance hole 6, in entrance hole 6, be provided with O-ring seal for to airtight to hole after threading, the top of circuit panel seat 4 is equipped with circuit board 7 and reflection shield 3 successively, circuit board 7 and reflection shield 3 are fixed on circuit panel seat 4 by screw, between circuit panel seat 4 and circuit board 7, scribble conduction oil, heat on can circuit board is delivered on housing 1 fast, dispels the heat.Uniform LED light source 2 on described circuit board 7, reflection shield 3 is the array being used in conjunction with LED light source 2, be to be equipped with independent reflection shield on each LED light source 2, make illuminating effect better, the top of circuit panel seat 4 and reflection shield 3 is provided with translucent cover 8, described translucent cover 8 is fixed on housing 1 by frame casting die 9, the back of described housing 1 uniform radiating ribs 10.Described screw rod on the housing 1 of entrance hole 6 outer ends is connecting mounting sleeve 11.Described mounting sleeve 11 is provided with plural radially Limit screw 12, during installation, by mounting sleeve 11, after being socketed on target body, Limit screw 12 is screwed.Described LED light source 2 is connected with the inlet-wire parallel on circuit board 7, when local LED light source burns, can not affect the normal work of other light sources.
