Description
Technical field
The utility model is related to a kind of attachment means of pipe pendant lamp tool.
Background technology
LED is the sensitive semiconductor devices of characteristic, and with negative temperature characteristic, thus needed to it in application process
Steady-working state and protection are carried out, so as to generate the concept of driving.Requirement of the LED devices to driving power supply is near severe
Carve, LED can be directly connected to the electric main of 220V unlike common incandescent lamp bulb.Because LED is sensitive half of characteristic
Conductor device, and with negative temperature characteristic, thus need to carry out it steady-working state and protection in application process, so that
Generate the concept of driving.Near harshness, LED, can unlike common incandescent lamp bulb for requirement of the LED devices to driving power supply
To be directly connected to the electric main of 220V.LED is 2~3 volts of low voltage drive, it is necessary to the complicated translation circuit of design,
The LED lamps of different purposes, will be equipped with different power supply adaptors.Effect of the foreign customers to LED driving power supplies on international market
Rate conversion, effective power, constant current accuracy, power source life, electromagnetic compatibility requirement it is all very high, design a good power supply necessary
These factors are considered, because effect of the power supply in whole light fixture is like important as human heart.Forward direction pressure
(IF) relation curve of drop (VF) and forward current, from curve, when forward voltage is more than certain threshold value (about 2V), i.e., generally
After described conducting voltage, can be approximately considered, IF is directly proportional to VF.Be shown in Table be current main ultra-bright LED electric spy
Property.As seen from table, the highest IF of current ultra-bright LED is up to 1A, and VF is usually 2~4V.Because the light characteristic of LED leads to
Often all it is described as the function of electric current, rather than the function of voltage, the relation curve of luminous flux (φ V) and IF, therefore, using perseverance
Stream source drives and can better control over brightness.Additionally, the forward voltage drop excursion of LED than it is larger (it is maximum up to 1V with
On), and from the VF-IF curves in upper figure, the minor variations of VF can cause larger, IF changes, so as to cause brightness
Large change.So, using drive of constant voltage source it cannot be guaranteed that the uniformity of LED brightness, and influence LED reliability,
Life-span and light decay.Therefore, ultra-bright LED is generally driven using constant-current source.The temperature of LED and luminous flux (φ V) relation curve,
Understand that luminous flux is inversely proportional with temperature by figure below, half when luminous flux at 85 DEG C is 25 DEG C, and light output is at one 40 DEG C
1.8 times at 25 DEG C.The change of temperature also has a certain impact to the wavelength of LED, therefore, good radiating is that LED keeps
The guarantee of constant luminance.
The attachment means of existing pipe pendant lamp tool are installed and wasted time and energy, and there is potential safety hazard, cable because installing
It is damaged during rotation.
Utility model content
In view of this, the utility model purpose be to provide it is a kind of install time saving and energy saving, reduce potential safety hazard, cable no longer because
For the attachment means that the pipe pendant lamp being damaged when installing rotation has.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of attachment means of pipe pendant lamp tool, including screw and nut, the nut bottom inside are provided with gear
Circle, the back-up ring is integrally formed with nut, and the screw head is provided with the head of outwardly convex, the head and
The screw is integrally formed, and through nut inner side occiput and back-up ring clamping, the screw inside is in hollow setting to the screw,
Swing pipe is provided with the nut, the swing pipe bottom outside is provided with threaded portion, and the threaded portion is connected with nut thread.
Preferably, the nut is hex nut, nut is conveniently turned.
Preferably, the screw bottom is provided with light fixture, keep lamp installation convenient.
Preferably, the relevant position that the light fixture is installed with screw is provided with screwed hole, screw is easily installed with screwed hole
And dismounting.
Preferably, the internal diameter of the back-up ring is more than the diameter of screw, screw can pass through back-up ring.
Preferably, diameter of the internal diameter of the back-up ring less than head, head can block back-up ring prevents screw from dropping.
The utility model has the technical effect that following aspect：The nut of setting is caused without having light fixture in arms again in height
Rotating in air, directly twists nut, and light fixture and swing pipe are motionless, so time saving and energy saving, so as to reduce potential safety hazard.Cable is in swing pipe
It is internal to be no longer damaged when rotating because installing.
