Two or more lamps can be assembled into a whole for doubling illuminance to use. The two-way non-redundant drive divides the LEDs into two independent paths, and only one path of the LEDs goes out when being damaged, thus preventing from causing loss at certain occasions and gaining the time for maintenance; with the use of the conductive interface materials, the technological process is simplified, and the conductive efficiency is improved; and the whole lamp is better in heat dissipation and more compact in structure through various structure layout of the shell. With the structure, the power consumption is reduced, the installation and use are fast and convenient, the stability of the whole lamp is improved, and the service life is prolonged.

Description

BLF series anti-explosion LED floodlight structure

Technical field

The utility model relates to a kind of anti-explosion LED floodlight, relates in particular to a kind of BLF series anti-explosion LED floodlight structure.

Background technology

The explosion-proof light lamp source in petrochemical industry place mostly is high-pressure mercury lamp, and mercury lamp, Metal halogen lamp etc., these lamps can produce a large amount of heats in lighting process, and luminous efficiency is on the low side, and power consumption is bigger.By contrast, LED is as cold light source, has characteristics such as low energy consumption, low-loss, low maintenance, low-voltage, life-span be long, ageing-resistant, and explosion-proof performance is good, can realize lighting energy saving.The LED Lighting Industry keeps high growth speed in recent years in the world, and the LED luminous efficacy constantly promotes, from the illumination development trend we as can be seen, LED is one of light source that meets its development trend.But at present the anti-explosion LED light fixture mainly shows poor reliability, manufactures complicatedly, and the LED illumination life-span of being known as 100,000 hours shows as the owner and spends that the mint of money expectation obtains durable reliable hope and real difference is very big.In actual conditions, owing to heat conduction, dispel the heat, install and use system design and implement not good enoughly, the LED light fixture is aging fast, the circuit complexity, and the drive circuit loss is big, and the cost height has influenced the application of LED light fixture.

Compared with prior art, the utility model anti-explosion LED floodlight drives and driving method, not that simple mechanical ground is made in two drive circuits of not theing least concerned on the same PCB, the drive circuit that two-way output neither one can be arranged, but, creationary latter half is divided into two-way with a drive circuit that proves efficiently, stablizes, simplifies through use.Comprise a power input terminal, current rectifying and wave filtering circuit, two IC and circuit thereof, a lead-out terminal; Described drive circuit, 175V～265V alternating current is divided into two-way through behind the same current rectifying and wave filtering circuit, through two groups of constant-current control circuits, obtains independently two-way direct current output, and each connects the led light source of one group of series connection, and two groups of light sources are separate.Adopt the advantage of two-way nonredundancy type of drive to be: to reduce element, reduce cost, reduce the wastage, improve load capacity.

On the light fixture production technology, reduce the number of the technology of LED and lamp housing, center fixed from the luminescent system to the cooling system and heat-conducting interface material adopt pressure-sensitive stickup heat-conducting interface material, simplify and manufacture complexity.This material has excellent high temperature performance, machinery and chemical stability.Replace heat-conducting cream, heat-conducting silicone grease, do not have dirty being bored with, pollute; Permanent bonding, replacement heat-curable glue, heat-conductive bonding agent, screw, compressing tablet are fixed.

As further improvement, the pack alloy shell is a radiator simultaneously, for the wire connection cavity of protuberance, for lamp body better dispels the heat, designs sheet radiating ribs structure in the middle of the lamp housing back, and it is trapezoidal that shape is groove.The shell back is a radiating ribs, and the lengthy motion picture radiating ribs is established the groove mouth.

Install and fix and use support and bolt, shell has all been reserved installing hole for four jiaos, and support of every lamp gets final product according to using needs to select for use two holes on one side to install when installing and using.Use same support, both can carry out vertical installation, also can carry out horizontal installation.

For realizing above-mentioned another purpose, two or more light fixtures can be assembled into one with bolt, double illumination and use.Designed the structure of assembly unit on the shell, during use two corresponding positions of lamp being stitched together tightens and can be integral with bolt, and two lamp electrical wirings are parallel form, a shared input cable.Assembly unit or do not need assembly unit to use, set structure all is the part of radiator, and is neither unnecessary, also not burdensome, shell is by multiple topology layout, make whole light fixture heat radiation better, more compact structure.
