30w solar street light price Certification: CE / ISO9001 / RoHS / 3C / CQC // UL / TUV Delivery time: 5-15 days Payment terms: L/C, D/A, D/P, T/T, Western Union, Money Gram, Service: OEM/ODM customization Qingdao Shanghai Shenzhen Port Supply capacity 5000 Solar integrated street lighting sources are divided into COB and LED. COB is one of the LED lighting fixtures. COB is the abbreviation of chip-on-board, which means that the chip is directly bonded and packaged on the entire substrate, and N chips are integrated together. Packaging is mainly used to solve the problems of low-power chip manufacturing high-power LEDs, etc. It can disperse the heat dissipation of the chip, improve the light efficiency, and improve the glare effect of the LED lamp; all in one solar street light COB has high luminous flux density and less glare It is soft and emits a uniformly distributed light surface. Currently, it is widely used in solar street light bulbs, spotlights, downlights, fluorescent lights and street lights. solar powered cob street light with auto intensity control.

Good precision, low false welding rate, light weight, small size, etc.; cob street light solar system. Of course, there is also MCOB, which is commonly referred to as Muilti Chips On Board, which is a multi-decent integrated packaging method, so it is an expansion of the COB packaging process. MCOB packaging is to put the chip directly in the optical cup, in each single The chip is coated with phosphors and the dispensing process is completed. The LED chip light is concentrated inside the cup, so more light should escape. The more light outlets, the higher the light efficiency. The efficiency of MCOB low-power chip packaging Generally higher than the efficiency of high-power chip packaging. It directly places the chip on a substrate heat sink such as metal, thereby shortening the heat dissipation path, reducing thermal resistance, improving the heat dissipation effect, and effectively reducing the junction temperature of the light-emitting chip; FAQ Q:Are you a factory? A:Yes! we are a factory of led solar street lights for 8 years. Q:It does not light on in rainy days, the lamp has short light on time A:We increase the battery and solar panel capacity,smart mode for time brightness,1 day full charged,2-3 working Q:The lamp enter water,not waterproof. A:The whole lamp is IP65,controller:IP67,use electric glue Q:Will the lamp is so dark? A:Use Seoul led chip,160LM/W,very brightness,LED module design,84pcs-252pcs led chip Q:If the battery damage,how to change? A:We have video teaching +sales consultant assistant within warranty,it change for you free. Q:How to install solar street light?
