Abstract
The utility model discloses an intrinsic safety portable lamp relating to an electrical apparatus for an explosive gas environment. The utility model has the characteristics of favorable explosion protection performance, high brightness, little heat generation, long discharging time, long service life, etc. A luminous body of the utility model is a superbright LED module, and a wide voltage input drive circuit is arranged between an input power and the luminous body. A transparent lamp shade and a lamp body are welded by ultrasonic wave to become integration which is free from maintenance. The utility model is mainly used for manufacturing the portable lamp.
Description
Technical field
The utility model relates to a kind of explosive gas atmosphere electrical installation, relates in particular to a kind of essential safe type portable lighter.
Background technology
Portable lighter of the prior art installs protection network additional by common lamp socket to be formed, and illuminator adopts common bulb to be threaded with lamp socket, produces a large amount of heats during use again, can not satisfy requirement of explosion proof.
Summary of the invention
The utility model has proposed a kind of essential safe type portable lighter at deficiency of the prior art, and it has good explosion-proof performance, the brightness height, and heating is few, and discharge time is long, characteristics such as long service life.
This programme is realized by following technical measures: comprise lamp housing, be positioned at the lamp housing front end Transparent lamp shade, be arranged at the illuminator of lamp housing inside, described illuminator is the superbright light-emitting diode (LED) module, is provided with wide voltage input driving circuit between input power supply and illuminator.
The beneficial effect of this programme can be learnt according to the narration to such scheme, described illuminator is the luminous utmost point tube module of superbright, between described power supply and illuminator, be provided with wide voltage input driving circuit, guarantee to realize function to the illuminator power supply, the utility model compared with prior art, adopted cold light source, heating is few, the technical purpose that has realized.
The concrete characteristics of this programme also have, and described superbright light-emitting diode (LED) module is made up of 4 groups, every group 22 superbright light emitting diodes, can satisfy the requirement of illumination.Also can determine superbright light emitting diode quantity according to the needs of actual conditions.Be hermetic seal between described Transparent lamp shade and the lamp housing, guarantee the realization of its explosion prevention function; Be ultrasonic bonding between described Transparent lamp shade and the lamp housing, can realize the sealing of lamp housing and lampshade easily, make it to become one, non-maintaining.Also can adopt epoxy sealing or adopt plug connector to fasten sealing.Described wide voltage input driving circuit comprises that glue is enclosed in light source module and power module together, realizes the power supply to light source module.Being connected between described holder and the lampshade is meant, on the holder top projection is set, and at the lamp socket bottom outer surface 2 sections clamping plate is set, clamping plate inwall and this projection match and, be provided with bolt between 2 clamping plate, realize fixing to the essential safe type portable lighter.
