Description
Technical field
The utility model is about a kind of lamps and lanterns, espespecially a kind of flat illuminator.
Background technique
Illuminator is most widely used a kind of life appliance in daily life.General illumination lamps and lanterns are mostly with fluorescent lamp
Light sources of the pipe as lamps and lanterns.Micro argon and mercury vapour would generally be added in fluorescent tube.Mercury is an a kind of toxic huge sum of money
Belong to substance, not only can environment pollute, if fluorescent tube is accidentally broken and sucked by people, people's body will be will cause
Injury.Therefore, for environmental protection and the consideration of energy conservation, more and more illuminator systems are with the substitution of light emitting diode (LED) lamp bar
Fluorescent tube is as main light emitting source.The power consumption of LED illumination lamp is much smaller than traditional fluorescent lighting fixture, to become future
The optimal selection of illumination market.
LED illumination lamp mostly takes enclosed design at present.LED light bar and power supply group inside LED illumination lamp
Part is easy to be damaged because of the factor of poor heat radiation, however, the LED illumination lamp of closed design is to be not easy to be disassembled
, so that causing replacement or repairing the degree of difficulty of LED light bar and Power Supply Assembly.Furthermore previous LED light bar is usually sticked together with special
Agent is directly attached on the lamp holder of the lamps and lanterns of tool heat radiation function, to remove the LED light bar of damage from lamp holder, also to be taken
Mental and physical efforts.Therefore, if there is a situation where LED light bars or Power Supply Assembly to damage for LED illumination lamp, user is typically only capable to selection and loses
LED illumination lamp is abandoned, and purchases a completely new LED illumination lamp.Here, only being abandoned because of the damage of part electronic building brick entire
LED illumination lamp, not only results in the waste of resource, and will increase the cost of user's lighting demand.
