Solar street lamps of 120 w street light choose acceptance method 1

LED light source selection methods: simple in every LED light lamp bead used under the condition of same quality, to look at the radiator of the LED light source whether meet the heat dissipation of LED lights. The best light for an hour or two, if behind the radiator special hot, more than 65 degrees, to illustrate the lamp



the LED light source' LED light source is the light emitting diode ( 领导) For light source of light. 】 Choose simple way: in every LED light lamp bead used under the condition of same quality, to look at the radiator of the LED light source whether meet the heat dissipation of LED lights. The best light for an hour or two, if behind the radiator special hot, more than 65 degrees, not that this kind of lamp, heat dissipation is not enough, long time use light failure will be very big, reducing the life of the lamp bead; If don't feel very hot, the radiator and the aluminum plate, light bead feel very hot, then radiator cooling effect, the LED lamp bead can't cooling, long-term use of the same droop is very big, reducing the life of lamp bead. The simplest method is in the lights for an hour or two later, with the hand to touch the radiator, if it's a little hot but people can accept, this product is a choice. For solar street lamps installed after the acceptance to the point of the effect of the company measured ground illumination 【 Ground illumination is refers to the space radiation directly on the ground to the light energy on the ground. 】 Minimum to hit 15 lux, in order to guarantee the basic human needs.
