Abstract
An anti-explosion maintenance-free energy saving lamp solves the problems that the conventional anti-explosion lamp is provided with a power supply and a light source arranged in one chamber together, and the light source generates too much heat, resulting in burnout of a circuit board or external explosion. The anti-explosion maintenance-free energy saving lamp comprises a power supply unit, a light source unit, a power supply casing surrounding the power supply unit, and a light source casing surrounding the light source unit. The light source unit comprises an energy saving bulb, the power supply casing comprises a power supply cavity lower cover, the light source casing comprises a light source cavity upper cover, pipelines through which light source leads can pass are arranged between the power supply cavity lower cover and the light source cavity upper cover, and cooling fins are arranged between the power supply cavity lower cover and the light source cavity upper cover. The anti-explosion maintenance-free energy saving lamp has the benefits that the cooling fins are arranged between the power supply cavity lower cover and the light source cavity upper cover, so as to support the casings, facilitate the heat dissipation of the light source casing, avoid the problem of circuit burnout caused by too much heat which is generated by the light source and transmitted to the circuit board, prolong the service life of the product, and enhance the safety of the product during the use.
Description
Technical field
The utility model relates to a kind of explosion-proof maintenance-free energy saving lamp.
Background technology
Explosion-proof lamp refers to the light fixture for the various certain measures that prevent from lighting explosive mixture on every side such as explosive gas atmosphere, explosive dust atmosphere, methane gas etc. and take.The important explosion-proof principle of one of them of explosion-proof lamp is exactly the problem temperature on the restriction case surface, component surface or the electronic devices and components surface that contact with damp, explosive dust, and restriction electrical contact surface temperature is lower than its minimum ignition temperature or ignition temperature.The blast medium of lamp interior, because inner element is ignited it, airtight shell can not be transmitted to the blast of inside in the outside overall situation.Traditional explosion-proof lamp power supply and the light source Room that exists together, the heat that produces in power supply and the light source works process adds up, and the heat radiation effect of heat insulation is bad, causes the lamp casing surface temperature to raise.The power supply temperature raises and burns out easily circuit board, affects service life, and may cause static and electric spark, when casing surface temperature is higher than its ignition temperature or ignition temperature, may blast.
Summary of the invention
For solving in the background technology existing explosion-proof lamp power supply and the light source Room that exists together, the heat that light source produces is too much, burns out easily circuit board or causes the problem of the blast of outside, and the utility model provides a kind of explosion-proof maintenance-free energy saving lamp.
The technical solution of the utility model is: a kind of explosion-proof maintenance-free energy saving lamp, comprise power subsystem, light source cell and wrap separately its outer power shell and light source shell, described light source cell comprises energy-saving bulb, power shell comprises power source cavity loam cake and power source cavity lower cover, described light source shell comprises light-source chamber loam cake and light-source chamber lower cover, be provided with between described power source cavity lower cover and the light-source chamber loam cake for the light source wire pass pipeline, be provided with fin between described power source cavity lower cover and the light-source chamber loam cake.
As a kind of improvement of the present utility model, described pipeline is two.
As another kind of improvement the of the present utility model, connect by pipeline between the exterior surface on exterior surface and the light-source chamber under the described power source cavity and form annular gap slot, described fin is located in the annular gap slot.
As another kind of improvement of the present utility model, described fin and the moulding of light-source chamber loam cake integrally casting.
The beneficial effects of the utility model are, be provided with fin between power source cavity lower cover and the light-source chamber loam cake, fin not only plays support to housing, and is more conducive to the heat radiation of light source shell, has avoided heat of light source too much to be delivered to the problem that circuit board burns out circuit, because heat dispersion is better, properties of product are reliable, and are more safe when product is used, simultaneously also so that the long service life of product, at least in 2 years, can not damage, can reach non-maintaining effect.
