Abstract
The utility model discloses a digital ballast with a double-air channel heat radiation structure. The digital ballast comprises a housing and a power supply wire. The housing is provided with heat dissipation teeth. A PCB board is arranged inside the housing. The two sides of the PCB board are provided with heat dissipation fins. Two air channels are formed among the two heat dissipation fins and the housing. Two ends of the housing are respectively provided with a left end cover and a right end cover. The left end cover is provided with a turn button, a turn button light modulation panel, a left fan and a left air hole. The right end cover is provided with a right fan, a socket and a right air hole. The left air hole and the right fan are arranged on two ends of one air channel. The left fan and the right air hole are arranged on two ends of the other air channel. Compared with the prior art, the digital ballast with the double-air channel heat radiation structure has the advantages that by adopting the above combination of the fans, the fans and the heat dissipation fins form the double air channels, and superfluous heat of a radiator can be discharged to the largest extent, so that the heat dissipation effect is better, the working temperature of the product is lowered, and the reliability of the product is substantially improved. In addition, an integrated metal housing structure is adopted, so that the digital ballast with the double-air channel heat radiation structure is also attractive in appearance.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of electric lighting, relates in particular to the digital ballast of a kind of pair of air-channel heat-dissipation structure.
Background technology
Along with the enforcement of China Green Lights Project, for digital ballast, to apply and paved road, green energy conservation high-intensity gas discharge lamp digital energy-saving device has obtained developing fast and promoting, and is applied to every field.Be accompanied by the development in market, user's requirement is more and more high, and user is no longer satisfied with the digital ballast that structure is single, and the application of digital ballast is more and more wider, and the digital ballast of breaking through traditional structure is imperative.
And be accompanied by the development of electronic technology, a lot of digital ballasts the performance of electronic devices and components more and more stronger, meanwhile sharp rising also appears in power consumption, its caloric value also significantly rises, therefore, how to improve the radiating effect of these heat abstractors, become the significant problem that present digital ballast technology must solve.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, provides the digital ballast of a kind of pair of air-channel heat-dissipation structure.
Above-mentioned purpose of the present utility model realizes by following technical scheme: the digital ballast of a kind of pair of air-channel heat-dissipation structure, comprise shell and power line, shell is provided with radiation tooth, in shell, be provided with pcb board, it is characterized in that: described pcb board both sides are provided with fin, between two fin and shell, form two air channels, shell two ends are respectively equipped with left end cap and right end cap, left end cap is provided with knob, knob light modulation panel, left fan and left pore, right end cap is provided with right fan, socket and right pore, described left pore and right fan are positioned at two ends, air channel, described left fan and right pore are positioned at another two ends, air channel.
Described fan is provided with guard.
Described shell is made of metal.
Described pcb board is integrated with single chip machine controlling circuit, input power factor correction circuit, resonant circuit and power driving circuit.
The utility model advantage is compared with prior art: by combination of fans like this, fan and fin form two air channels, more can to greatest extent the waste heat of radiator be taken away, and radiating effect is better, reduce the working temperature of product, greatly improved the reliability of this product.In addition, adopt integrated metal shell structure, have aesthetic concurrently.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the digital ballast of a kind of pair of air-channel heat-dissipation structure of the present utility model, it comprises that end cap 3, shell 7 and end cap 13 form an airtight cavity; The fan 6,12 and the fin 8,9 that are arranged at shell two ends have improved radiating effect, have reduced the working temperature of product; Pcb board 10 comprises single chip machine controlling circuit, input power factor correction circuit, resonant circuit and the power driving circuit being integrated on same circuit board, has formed a digital ballast with new structure.
Mechanical structure, this shell 7 and the interior plum blossom groove of end cap 3,13 use recessed pan head tapping screw 4,14 are directly fitted to each other and form; End cap 3 one side attachings have socket 5, and there is an American power line 19 in the front of end cap 13 by cableties 18 attachings; One side attaching of end cap 13 has knob 15 and knob light modulation panel 11; By cross recess round end tapping screw 1,17, respectively guard 2,16 and fan 6,12 are fixed on to the front of end cap.
Above-mentioned embodiment is exemplary, is to be this patent to be comprised to the restriction of scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do be anyly equal to change or modify, all fall into the scope that this patent comprises.
