Many people did not know the secret of 6 m street lamp and inferior ones

LED high-power lamps and lanterns of industrial with high light efficiency, long life, no delay switch, environmental protection and energy saving, and many other advantages, is gradually replaced by energy-saving lamps, metal halide lamp light source of the most advanced lighting products, but due to the good and bad are intermingled, also can appear some quality problems, often

high-power leds for miner's lamp with high luminous efficiency, long life, switch without delay, environmental protection and energy saving, etc. It is the most advanced lighting products, and gradually replaced the energy-saving lamp and metal halide lamp and other light source. However, due to the manufacturer's quality is different, also can appear some quality problem. Inferior a miner's lamp is a common cause of damage is roughly as follows: 1) 。 The light source is bad; Assembly lamps and lanterns, technology not perfect, the light bead and radiator poor contact, uneven thermal conductive paste coating. In addition, if the poor quality of lamp bead itself, light will burn for a long time. 2) 。 Bad power supply; Power supply problems lead to some manufacturers use inferior power at a lower price. The quality of the product does not conform to the standard. After long time use, when the light after a period of time, they will see the burning light, flashing light or faint light. 3) The radiator to cut corners to achieve a good heat dissipation. The rise of temperature of the lamp is too high too fast. Damage of miner's lamp usually has the following repair methods: patch type can replace the whole lamp plate, high-power integrated can replace the light source. Should pay attention to heat transfer. If the power supply is broken, can only change directly. If due to the power light is not on, it is better to replace the light source.
