The light source of solar street lamps is basically led light source. In the process of our use, we often encounter the situation that LED is not bright. This is the scene of the death of LED lamp.
There are two causes of LED bead death lamp, one is LED leakage flow caused by large PN junction effect caused by local death lamp, the whole lamp work is not affected; Second, the internal connection of the LED lamp is disconnected, resulting in the LED without electricity flowing through the death of the lamp, resulting in the whole lamp can not work malformed.
Our company as a professional solar street lamp manufacturer, we have 15 years of solar street lamp production lessons, we put forward the following points of view on the prevention of death lamp. The wiring on the back of the solar panel is reverse buckle design, which can be gently pried open with a screwdriver. The wiring of the solar panel (red cap is connected to the positive pole line, black cap is connected to the negative pole line) corresponding to the positive and negative pole line separated from the black cap of the lithium integrated battery, and the wiring should be wrapped with electrical tape.
LED street lamp it is a kind of efficient solid state light source based on semiconductor PN junction formed with weak electric energy can emit light, in a certain forward bias voltage and injection current, injected into the hole in the P region and injected into the N region of electrons in the diffusion to the active region after radiation compound and emit photons, the electric energy directly into light energy. It is a solid cold light source, with environmental protection, no pollution, less power consumption, high light efficiency, long life and other characteristics, therefore, LED street lighting will become the best choice for energy-saving transformation.
First, prevent static electricity
Static electricity is very harmful to LED lamp beads. Any problem in any link will cause damage to the LED lamp bead, so that the function of the LED lamp bead becomes bad or even destroyed.
Solar street lamp LED lamp head wire lithium control battery white cap separated, wiring attention to use electrical tape wrap. Before workshop workers contact LED lamp beads need to put the static electricity of the human body, wearing anti-static means and other necessary methods.
Two, take the initiative to welding equipment
If you use the previous welding method manual welding must strictly control the welding temperature, this is because the use of manual welding, if the use of individual iron, iron temperature in 300-400℃ above, too high welding temperature will also cause death lamp. LED lead expansion coefficient at high temperature than about 150℃ expansion coefficient is much better, the internal gold wire solder spot will be too large because of thermal expansion and contraction of the welding point open, resulting in the death of the lamp scene.
In order to avoid the above picture, the professional manufacturer for solar street lamps, strict production process manual to employees dress, the production environment configuration and so on has carried on the concrete, and strictly implement the effective to avoid the scene in the production process to eliminate on-line production, guarantee the production quality of the solar street lamps and other lighting products, Reduce customer's current solar street lamp maintenance problems.
