Product characteristics:

1. The shell is formed by one-time die-casting of high strength alloy aluminium with excellent strength and explosion-proof performance. After high shot blasting, the surface of the shell is electrostatic sprayed with high pressure, strong adhesion of plastic powder, good explosion-proof performance and stainless steel exposed fasteners.

2. Professional secondary light distribution design makes the powder have good light distribution type. The lampshade uses high borosilicate glass, which has high transmittance and good impact resistance. It can make the lamp work normally in various harsh environments.

3. Lamps and lanterns are integrated structure, but the light source cavity, electric cavity and connecting cavity are independent, easy to install, disassemble and maintain, and reliable electrical performance.

4. The fourth generation green environmental protection, high-power white LED solid-state light source, high light efficiency, service life up to 50,000 hours, can achieve long-term maintenance-free;

5. The overall heat dissipation design of lamps and lanterns is excellent, with low energy consumption, soft light and no glare, which will not cause eye fatigue and improve work efficiency.

6. Easy to install and connect.

1) LED uses imported chips, the beads are packaged in the original factory, and the light efficiency requirement is not less than 120 LM/W.

2) The driving current of a single light source should not be less than 450 mA, the color temperature should be 5500 K, and the whole light effect should not be less than 100 LM/W.

3) The junction temperature of the light source should be less than 80 degrees, the lifetime of the light source should not be less than 50,000 hours, the luminous flux maintenance rate of 6,000 hours should be more than 97%, and that of 50,000 hours should be more than 80%.

4) The light source should be connected in series and parallel reasonably, and each bulb should be equipped with a voltage regulator to prevent the whole series of bulbs from being affected by the damage of a single bulb.

5) The tenderer shall provide the declaration documents of the light source.

Technical requirements for power supply:

1) Constant current drive power supply from well-known manufacturers should be selected, and the conversion efficiency of power supply should not be less than 92%.

2) The driving power supply should be wide voltage input, ranging from 90V to 264V.

3) Driving power supply should have over-voltage protection, over-current protection, short-circuit protection, lightning protection, surge protection, etc.

4) EMI of driving power supply should meet the requirements of EN55015, EMC of lamps and lanterns should meet the requirements of relevant national standards, and provide testing reports issued by authoritative institutions.

Order instructions for explosion-proof LED lighting (guardrail type) HRD92-E30hH:

1. Describe the product power and installation mode according to the site lighting requirements.

2. If you need wiring boxes, please specify them.

3. When the lamps leave the factory, they do not have cables. If you need distribution cables, please specify.
