Abstract
A kind of engine hatch lamp, including one or more light emitting diodes (" LED ") light bulb, wherein the head lamp can reduce the additional load that locomotive is up to 86% or so, design is in the head lamp case of locomotive, make the heat that one or more LED bulbs generate that ice and snow around engine hatch lamp can be prevented to be detained, and avoids being connected to electrical locomotive power and be used to start electronic device and/or the circuit damage of one or more LED bulbs.
Description
Technical field
The present invention relates generally to lighting system more particularly to a kind of engine hatch lamps.
Background technology
There are shortcomings for traditional machine Vehicular headlamps.One of disadvantage is exactly that traditional machine Vehicular headlamps are embedded in machine
In the head lamp case of vehicle.Sunk part, which is be easy to cause between head lamp leading edge and engine hatch lamp cover wall portion, overstocks ice and snow.
There is also a disadvantage, temperature of the head lamp when being used on locomotive may be up to 140 DEG C, have for traditional Halogen Headlamp
The danger burnt.
In addition, traditional insertion of machine vehicle LED (" the LED ") head lamp according to LED head lamp in locomotive head lampshade
Position is different, will produce heat, damages electronic device and circuit in LED head lamp.In addition, traditional LED head lamp includes head lamp
The heat that subsequent LED bulb generates, the ice and snow that head lamp gathers when which is not sufficient to melt locomotive use.
Existing conventional locomotive head lamp another disadvantage is that, head lamp will receive the impact of vibration when operation, increase head lamp
The danger of internal fragmentation.
Another of existing conventional locomotive head lamp is the disadvantage is that it needs to be replaced regularly and safeguards.For example, traditional halogen
Plain head lamp is up to 2,000 hours or so using duration.In addition, existing head lamp has higher additional load, can cause to fire
The waste of oil.
Therefore the engine hatch lamp needed at present should be able to generate heat, and heat is enough to avoid the accumulation of the ice and snow on head lamp,
Without to including in head lamp electronic device and/or circuit cause to damage.What is needed further exist for is that one kind improving locomotive fortune
The head lamp of the vibration force on head lamp is resisted in row, and the service life of head lamp is long, additional load is few.
Invention content
To overcome or alleviated by disadvantages mentioned above in the prior art, a kind of head lamp is provided, which can utilize the lamp of head lamp
The heat that source generates, avoids the accumulation and influence of ice/snow on head lamp.In one exemplary embodiment, the head lamp includes
One top and a lower part.The top includes a lamp source, a upper body, multiple fins and a pedestal.
In one exemplary embodiment, the lamp source includes one or more LED bulbs.The lower part includes a lower case
Body, a part for the interior electric device and/circuit including at least locomotive power supply operation of the shell.Lower part is mounted on the head lamp of locomotive
When on cover, it should be placed in the cavity formed in locomotive head lampshade, a part for pedestal is formd using engine hatch lamp cover wall portion
A part for the sealing of inner wall, the pedestal, multiple fins and upper body is exposed in surrounding air, so that top includes
Heat given out from lower part, avoid in lower part electronic device and/or circuit cause to damage.
Therefore, engine hatch lamp is mounted on the position in locomotive head lampshade, it is ensured that the top comprising heat-producing optical sources is far from machine
Vehicle protrudes outward, and is exposed in surrounding air.The heat that lamp source generates in this way can lead to heat transfer for avoiding around head lamp
The delay of ice and snow.
Preferred lamp source includes one or more LED bulbs, such light bulb can substantially reduce additional load, compare general halogen
Plain light bulb is reduced maintenance requirement, while reducing the danger brought using halogen bulb.Head lamp of the present invention passes through
Using one or more LED bulbs as lamp source, the existing higher operation of maintenance of currently preferred army grade LED bulb is overcome
The problem of temperature.In addition, the head lamp can ensure that, and when head lamp is mounted on locomotive head lampshade, one or more LED bulb productions
Raw heat is kept apart with the circuit and/or electronic device powered for one or more LED bulbs.
In conjunction with following detailed description and refer to the attached drawing, above-mentioned and other features and advantage of the present invention can be more understood.

Specific implementation mode
Engine hatch lamp disclosed by the invention is exclusively used in the heat that optimization head lamp lamp source generates.In an exemplary embodiment
In, the head lamp includes a top and a lower part.
The lower part include at least head lamp be mounted on locomotive head lampshade in when start light source needed for electronic device and/or
A part for circuit, and place the lower case of the electronic device and/or circuit.
The top includes a lamp source, upper body, multiple fins and a pedestal for placing lamp source.It is described
Lamp source preferably include one or more LED bulbs.It using one or more LED bulbs is proved that locomotive can be reduced and is up to 86%
The additional load of left and right, and then save significantly on fuel cost.In addition, traditional halogen bulb is compared, the maintenance needed for LED bulb
It is few, and Halogen Headlamp about 2 is compared, 000 hour service life, the service life of the engine hatch lamp is about 40,000
Hour or more.
In addition, the LED bulb selected in engine hatch lamp can generate enough heats, to avoid mounted on locomotive head lampshade
On head lamp around be detained ice and snow, and when in use, and can ensure that LED bulb can bear operation high temperature.In an exemplary reality
It applies in example, one or more LED bulbs may produce up to the general power of 50W or so, can last up to 100 DEG C or so
Running temperature.
It, can after upper body, multiple fins and the pedestal is mounted on as the structure of head lamp in locomotive head lampshade
