1、 Disconnection. For "dead light", we should first determine major Multi function street lamp Is it short circuit or open circuit. 2、 The adhesive layer is peeled off. For some LED energy-saving project lights with vertical chips, the common reasons for dead lights are the peeling off of the bottom of the chip bonding layer and the peeling off of the bracket coating. 3、 The welding spot is burnt. In some cases, the dead light of the bulb may not be caused by the bulb itself, but also by the power supply used. 4、 Chip corrosion. The previous energy-saving floodlights and energy-saving floodlights are open circuit. The following is the condition of short circuit dead light. major Multi function street lamp There are many reasons for dead lights. Dead light may appear in every link from packaging, application to use.

install major Multi function street lamp The construction site shall be provided with safety slogans, warning signs and safety operation instruction boards, which shall not be removed or moved at will.

fixed major Multi function street lamp There are many methods, such as ceiling, embedded, hoisting (straight pipe or chain) and wall absorption. Generally, open lamps are usually used indoors. Enamel surface reflector shall be selected, with thick aluminum oxide film or aluminum reflector coated with silicon dioxide protective film. Movable local illuminators are equipped with corresponding handles, hooks, clamps, etc. Fixed local illuminators are usually firmly locked on the working machine by screws or fixing mechanisms. For large factories and large machine tool places requiring separate lighting major Multi function street lamp Reflectors made of materials with strong light control characteristics, such as prismatic glass, mirror glass and polished aluminum, to obtain narrow beam distribution.

1. Quality assurance, green and environmental protection, our LED lamp has a long life, low light attenuation and high brightness. They are the first choice for energy-saving transformation of factories. 2. Energy saving. The service life of Danohangpu LED products can reach 50000 hours, and the energy-saving effect is 40% - 60% of that of ordinary lamps, greatly reducing the power consumption. 3. Professional major Multi function street lamp Plan and plan. Make a reasonable lighting configuration plan according to the width of the road and the lighting time of the area, so that you will not waste money and reasonably configure the light source. 4. Professional technical guidance and after-sales service, professional technical team major Multi function street lamp We provide on-site technical guidance and problem solving for the installation and transformation of. Perfect after-sales service is our intimate guarantee for users. 5.

1. High purity aluminum reflector, accurate beam and good reflection effect. 2. Symmetrical narrow angle, wide angle and asymmetric light distribution system. 3. The rear open bulb can be replaced, which is easy to maintain. 4. The lamp is equipped with a dial to adjust the lighting angle. major Multi function street lamp Controlled by the built-in microchip. In small engineering applications, it can be used without a controller, and can achieve gradual change, jump, color flicker, random flicker. DMX can also control dynamic effects such as gradients to achieve effects such as chasing and scanning. Its main application places may be: single building, exterior wall lighting of historical buildings, interior and exterior lighting of buildings, interior local lighting, green landscape lighting, billboard lighting, medical culture and other professional facilities lighting, bars, dance halls and other entertainment places major Multi function street lamp 。
