Description

The LED lamp

Technical field

The present invention relates to LED light lamp, especially a kind of fluorescent tube arrangement of LED lamp.

Background technology

Big energy-consuming during common tungsten lighting, heat dissipation capacity is big, and bulb is frangible, and the life-span is short.The LED light emitting diode has plurality of advantages such as energy consumption is low, pollution-free, radiationless, volume is little, brightness is high, the life-span is long, belongs to by universally acknowledged environmental protection light source.At present on decorative lightings such as most indicator lamp, neon light, obtained vast application.And national governments all encourage growth LED technology with energy savings.

Led lamp is compared with traditional halogen tungsten lamp, and following advantage is arranged:

1, reaction speed is fast.Common based on halogen bulb has a delay from the power connection to the filament light-emitting, be exactly the temperature rise time of filament.For 12 volts 30 watts bulb, this time approximately is 0.2-0.35 second.Suppose that an automobile travels for 80 kilometers with speed per hour, this is equivalent to the braking distance of 4-7 rice.And lighting of LED postpones to have only for tens nanoseconds, can ignore.

2, identification effect is good.The reference color temperature of LED wide (1000-9000K), luminous intensity height (can up to 20000CMD).

3, long service life.Domestic LED nominal life was 6-10 ten thousand hours, and actual life is about 3-8 is ten thousand hours.And common halogen tungsten bulb has only 300-1000 hour life-span.

4, luminous efficiency height.The luminous efficiency of halogen tungsten lamp is approximately 18%, in other words the bulb consumption electric energy become heat more than 80% and infrared ray has lost.And the visible light luminous efficiency of LED surpasses 95%, and it is low to produce heat during work, is real cold light source.

5, earthquake-proof function is strong.Jolt in the vehicle traveling process and shake, and vibrations damage the tungsten filament of halogen tungsten bulb easily, fatigue fracture takes place in long-time use the easily.LED does not have complicated combining structure and relative movement part, and earthquake-proof function is very good.

6, energy-saving effect is excellent.Common 5 electric energy of being consumed of braking are equivalent to start the electric energy that engine consumed No. one time.Because the power of motor is about 300W during ato unit, endurance period 0.8-2 second; And the about 60W of the power of Brake lamp, the time 2-10 second of at every turn braking is so the braking in travelling just equals frequent ato unit.And single automobile-used LED operating current is approximately 20mAh, and the power consumption of LED light fixture group is equivalent to 1/10th of halogen tungsten lamp.

LED has above-mentioned plurality of advantages, but the optical beam ratio of common LED lamp is more concentrated, and angle is narrower, can not reach the astigmatism of illumination as ordinary lamps, and therefore present LED can not reach the requirement of lighting source, can't replace common bulb and be used for illumination.
