Performance of LED flashlight

It is told that when LED flashlight just stepped into China, it use number of world-leading technologies. For example, simplifying the design style split charging mode, SOS emergency call and switch tactics, but also waterproof and dustproof, scratch resistant and other features, the performance and product safety features are very powerful.

Professionals have pointed out that they hope more high-performance LED flashlights add to the general lighting among consumers' lives, from another point of view, along with the government's policy to promote low-carbon green and consumers enhance the concept of green energy, low-carbon, high-performance product sales performance, LED flashlight barrel class will have a greater development.

According to reports, base on the energy category premise, in order to highlight the effect of lighting, LED flashlight use a nano-colloidal lead-acid batteries. This type of battery use thermal disposal and nanotechnology surface to modified powder, and after monitoring of the sol-gel process disturbances produced by sol-gel process, the gelled electrolyte to increase the total capacity of the battery is increased to complete the object, avoid battery leakage of liquid and electrolyte fluid level separation phenomenon occurs, reducing the corrosion rate.

Troubleshooting
1, when LED does not light, replaces the LED on it, but to pay attention to ± polarity cannot be reversed.
2, lead-acid batteries are damaged, resulting in not charging and discharging, the performance of plug to use.
3, high-voltage step-down capacitor is damaged, or rectifier diode overvoltage damage caused cannot be charged, this time with an ordinary pointer millimeter can detect and solve the problem.
4, pull switch is bad or damaged cannot be turned on.

Existing lighting strips do not allow a combination of flexibility and rigidity desired buyers to configure rope lights into any selected configuration with ease. anty881209wong 140415 Color chasing and color mixing capabilities are limited.A led flexible strip device includes an elongated flexible tube with a translucent tube LED bulb shell and opposed tube ends and a flexible circuit board set in the tube so that it extends between the tube ends. The flexible circuit board has opposed interior and exterior surfaces. Electrical circuitry is mounted to the circuit board and connected to an external input source and an output source of electrical power.All LED Strip Lights should feature easily recognizable 'cutting points' spaced periodically along their length. This is where you should cut if you intend to do it yourself using a sharp knife or pair of scissors. If you do find you need to do any LED String Light soldering you will also find a series of solder points (2 for single color LED Strip Lights and 4 for RGB LED Strip Lights) to which your 2-core or 4-core cable can be attached. Learn some useful use trip on LED strip light can help you be easier when installing the light for your house. The cutting is an important point for using the LED strip light.

What do you know about LED light

Because most of the LED technology is still too inadequate, so for the first using on lamps drawbacks include light quality (CRI, consistency, and color temperature) is poor, heat is not easy, and the price is high, improper cooling which will result in brightness LED lighting components and circuit life accelerated decay.

With the mmanufacturing technology advances, the above-mentioned drawbacks, including LED thermal resistance decreases, also enhance the quality of light. 2008, cold white LED luminous efficiency has reached 100 Lm / W, and warm white LED luminous efficiency is expected in 2010, also available from the 70 Lm / W increased to 100 Lm / W.

Compared with other common sources, incandescent light bulbs is about 15 Lm / W, fluorescent lamp about 45 ~ 60 Lm / W, HID lights about 120 ~ 150 Lm / W, LED luminous efficiency is clearly a competitive advantage gradually; following is a LED lighting lamps and other’s common comparison:



Lighting system
features
White light LED

Less heat, wide operating environment, miniaturized, shock-resistant, concentrated beam.
Fluorescent lamp
Power saving, but friable waste mercury will cause pollution problems.
incandescent light bulbs
Low efficiency, high power consumption, short service life, fragile.


An amount of advantages goes with application them. When compared to beaming and beaming ablaze bulbs. LED light bulb is abutting to 1/10 beneath ability consumption. LED light bulb also abides 50 to 100 times best as adjoin accepted bulbs, or accumulation 100,000 hours' use adjoins 10,000 hours for CFLs or bunched ablaze bulbs. LED light bulb is abundant added bunched in measurement and are sturdier.
