Abstract
A factory explosion-proof and intrinsically safe LED lamp relates to the improvement of an explosion-proof lamp structure. The utility model provides a factory explosion-proof and intrinsically safe LED lamp with characteristics of safety and environmental friendliness, a small size, and low electricity consumption. The factory explosion-proof and intrinsically safe LED lamp comprises a LED lamp body and an explosion-proof power case. The power output end of the explosion-proof power case is connected with the power input end of the LED lamp body. A structural key point is that the explosion-proof power case uses a switching power supply.
Description
Technical field
The utility model relates to the improvement of flameproof lamp structure.
Background technology
Existing explosion-proof lamp generally has incandescent lamp, explosion-proof high-pressure mercury lamp, explosion-proof low-voltage fluorescent lamp, mixed light lamp etc.Traditional explosion-proof lamp mostly is non-intrinsic safety lamp, must be to lamp holder flame proof and luminous efficiency is low, the power consumption large, volume weight is large, the response time is slow (starting time is long) in addition, and unstable (certainly putting out phenomenon when network voltage is low), working life are short.Because it has a lot of weak points, make reliability and the difficult quality guarantee of product.
Summary of the invention
The utility model is exactly for the problems referred to above, and a kind of safety and environmental protection, volume is little, power consumption is low station-service Flameproof and intrinsically safe LED lamp are provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises LED lamp body and flame proof power supply box, and the power output end of flame proof power supply box is connected with the power input of LED lamp body, the power acquisition Switching Power Supply of the described flame proof power supply box of its structural feature.
As a kind of preferred version, Switching Power Supply described in the utility model adopts the PT4201 chip.
As another kind of preferred version, the output dc voltage of Switching Power Supply described in the utility model is 12V.
Secondly, the TLP181 photoelectrical coupler is partly adopted in the feedback regulation of Switching Power Supply described in the utility model.
In addition, the model of the switching tube of Switching Power Supply described in the utility model is 2N60.
The utility model beneficial effect.
1, long working life.
As a kind of semiconductor solid luminescence device, has longer working life than other photophore; Its brightness half-life can reach 100,000 hours usually, has need not repair all the life and the characteristics of changing.
2, power consumption is low.
Be a kind of operating on low voltage device, therefore under equal brightness, power consumption is minimum, can reduce in a large number energy consumption.
3, the response time is fast.
Generally can respond within tens nanoseconds, be therefore a kind of high speed device.
4, volume is little, lightweight, anti-resistance.
Volume is little, lightweight, anti-resistance.
5, safety and environmental protection.
There are not environmental contaminants such as mercury, lead in the light source of making of LED, does not pollute the environment.In addition, the utility model Switching Power Supply is supplied with LED work through the direct current of over commutation, filtering, pulse-width modulation, transformer isolation stable output, improved greatly security reliability, and light source need not to add protector, the luminance of light source also is greatly improved simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described further.The utility model protection range not only is confined to the statement of following content.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model circuit theory diagrams.
In figure, 1 is that LED lamp body, 2 is the flame proof power supply box.
Embodiment
As shown in the figure, the utility model comprises LED lamp body 1 and flame proof power supply box 2, and the power output end of flame proof power supply box 2 is connected with the power input of LED lamp body 1, the power acquisition Switching Power Supply of described flame proof power supply box 2.
Described Switching Power Supply adopts the PT4201 chip.
The output dc voltage of described Switching Power Supply is 12V.The power output of Switching Power Supply can be 30W, operating current 340mA, short circuit current 120mA.
The TLP181 photoelectrical coupler is partly adopted in the feedback regulation of described Switching Power Supply.When output load current is excessive when being short-circuited, namely adopt the resistive short protection, photoelectrical coupler luminous tube both end voltage equals output voltage, and voltage is zero, and not conducting of luminous tube makes the PT4201 chip FB pin voltage protection threshold value of climbing fast.Be in 1K Ω situation at PT4201 chip Fosc pin, after 32ms, PT4201 with autoshutdown, had both played safety effect excessively, and was simultaneously energy-conservation again.
The model of the switching tube of described Switching Power Supply is 2N60.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection range of the present utility model.
