Description

LED energy-saving explosion-proof lamp

Technical field

The utility model relates to a kind of explosion-proof light device, particularly is a kind of LED energy-saving explosion-proof lamp.

Background technology

At present, employed explosion-proof lamp is arranged in damp and the dust atmosphere as high-pressure mercury lamp, Metal halogen lamp, mercury lamp, even electronic fluorescent lamp in industries such as oil, chemical industry, coals, power consumption is big, and it is many to produce heat, and the life-span is short, change often, had a strong impact on safety in production.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of simple in structure, the work LED energy-saving explosion-proof lamp that temperature rise is low, explosion-proof performance good, energy consumption is low.

LED energy-saving explosion-proof lamp of the present utility model comprises: joint, preventing bursting cap, pressure pad, sealing shroud, binding post, last connecting bolt, flame proof plate, porcelain socket, LED lamp holder, following connecting bolt, housing, fin, reflector, transition joint, pad, pressure ring, lampshade, guard shield.Its LED energy-saving explosion-proof lamp is the semi-round ball cone structure, the joint center is provided with through hole, top is provided with internal thread, the bottom is provided with external screw thread, the centre is six square nuts, be threaded dress pressure pad in the preventing bursting cap with preventing bursting cap, rubber sealing boot, preventing bursting cap are gone up connecting bolt with housing by three and are connected, the centre is provided with seal groove, plastics flame proof plate is provided with a pairs of posts, and screw is fixed on the top of housing, is connecting the porcelain socket successively, the porcelain socket is installed with the LED lamp holder, annular reflector is housed around the LED lamp holder, and transition joint is connected by following connecting bolt with the bottom of housing, and the centre is provided with seal groove, pressure ring is connected with the lower thread of transition joint, pad is equipped with in the centre, and lampshade is compressed, and lampshade is provided with guard shield outward.

Above-mentioned LED energy-saving explosion-proof lamp; its circuit is powered by the 220V power supply; the 220V alternating current through the step-down of C1 decompression capacitor after full-bridge rectification D again by C2 filtering after current-limiting resistance R3 provides constant-current supply for the LED of series connection; R1 is a protective resistance; R2 is that the discharge of unloading of capacitor C 1 hinders; R3 is that current-limiting resistance prevents that voltage from raising and the electric current of temperature rising LED increases; C2 is a filter capacitor; C2 is that dash current when being used for preventing to turn on light is to the infringement of LED; the moment of turning on light is because the existence of C1 has a very big charging current; this electric current flows through LED will produce damage to LED; the intervention of C2 has been arranged, and the charging current of turning on light is absorbed by C2 fully and has played the protecting against shock protection of turning on light.Decompression capacitor will adopt withstand voltage electric capacity of the dacron or CBB electric capacity more than 400V, and filter capacitor will be with more than the withstand voltage 250v, and at each LED Zener diode ZD in parallel, when the LED damage, the conducting of Zener diode ZD reverse breakdown does not influence the work of other LED.

According to the LED energy-saving explosion-proof lamp that such scheme is made, energy-efficient, light health; do not contain ultraviolet ray and infrared ray in the light, radiationless, environmental protection; and can not produce electromagnetic interference, vision protection directly drives; no stroboscopic, the optical efficiency height, 90% electric energy is converted into visible light; the safety coefficient height, required voltage, electric current are little, and it is less to generate heat; no potential safety hazard can be used for hazardous areas such as mining site.
