Description
Technical field
The utility model relates to the lighting device technical field, particularly relates to a kind of electrodeless lamp of uphanging.
Background technology
Electrodeless lamp also claims electromagnetic induction lamp, the branch that HF lamp without electrodes and low frequency electrodeless lamp are arranged, there are not traditional filament and electrode in the fluorescent tube, the high frequency ballast of application specific integrated circuit, launch the high-frequency electric wave energy, by the electromagnetic induction measure, the magnet ring that employing is wound with coil is enclosed within that fluorescent tube is outer to be coupled into this high-frequency electric wave energy in the discharge lamp that is filled with mixed inert gas and special mercury alloy, because operating frequency can reach 2.65MHz and 210KHz respectively, charging particle movement in the fluorescent tube makes the generation ionization of mercury alloy molecule and excites, produce the 253.7nm ultraviolet photon, these photons hit on the glass bulb inwall that scribbles fluorescent RE powder, will produce visible radiation.
Usually, electrodeless lamp structurally can be divided into three parts: radio-frequency generator 10, coupler and fluorescent lamp bulb 30.
As depicted in figs. 1 and 2, radio-frequency generator 10 (power supply that also claims electric ballast (ECG) or electrodeless lamp) input 220V electric main or input low-voltage DC (as 12V DC or 24V DC), be output as high-frequency alternating current, its frequency range is that 135kHz～13.56MHz (generally adopts two frequency range: 200kHz～450kHz, 2MHz～3MHz).The 220V electric main of input converts direct current to after rectification, filtering, by pierce circuit export after with dc inversion high-frequency alternating current (for example, 2.35MHz), again through the high-frequency alternating current of high frequency transformer output constant voltage, to offer power coupler 20.Power coupler 20 is made up of permeability magnetic material 21 and coupling coil 22, and the high-frequency electrical in the coupling coil 22 fails to be convened for lack of a quorum and induce high frequency magnetic field in permeability magnetic material 21.The magnetic loop of this high frequency magnetic field forms magnetic loop through fluorescent lamp bulb 30.The energy of high frequency magnetic field makes the mercury vapor discharge in the fluorescent lamp 30, forms electronics 41 and plasma 42.Be stimulated atom when returning ground state at plasma 42, give off the ultraviolet ray 43 of 254nm, the fluorescent material in the bulb is by ultraviolet ray excited and produce visible light 44.
Because no filament, electrodeless in the electrodeless lamp, product improves greatly with respect to traditional fluorescent lamp service life, can reach more than 60000 hours.In addition, electrodeless lamp also has advantages such as high light efficiency, high-color rendering, high power factor, wide operating voltage, instantaneous starting time weak point, and because it can make powerful lamp (arriving 300W as 200W), and acquisition application more and more widely.For example, electrodeless lamp goes for factory, school, greenhouse, auditorium, market, sports ground, traffic complex area (street lamp, identification light, bridge light) etc., is specially adapted to high-risk and changes the important place of lamp difficulty and maintenance cost costliness.Wherein, suspended lamp, it is particularly electrodeless that to uphang lamp comparatively common in the application in these fields.
Please refer to Fig. 3 and Fig. 4, it is a kind of existing electrodeless cutaway view of uphanging modulated structure schematic diagram and electric appliance box thereof along the A-A face.As shown in the figure.This is uphang lamp and comprises electric appliance box 1, suspended structure 2 and lampshade 3, wherein be provided with electric ballast in the electric appliance box 1, it is made of printed circuit board (pcb) 11 and ballast shell 12, wherein PCB 11 is provided with circuit structures such as rectification, filter circuit, oscillator and high frequency transformer, omit the components and parts such as resistance that its surface is provided with at this, so that other structures are more clear among the figure.As can be seen from the figure, have concave design on the inwall of ballast shell 12,, PCB 11 is fixed in wherein to hold PCB 11; And the baffle plate 16 of inwall both sides is in order to the components and parts on the protection PCB 11.The inwall bottom design of electric appliance box 1 has three projectioies 13,14 and 15, to support and fixed-ballast shell 12.17 in electric wire is drawn from pcb board, guides on the electrodeless lamp in the lampshade 3 by the ballast shell 12 and the hole of electric appliance box 1 bottom.
As seen, the existing electrodeless lamp of uphanging utilizes the ballast shell to fix ballast, and with its integral installation in electric appliance box.So, brought great constantly to fitting operation, and be unfavorable for the heat radiation of components and parts.
