Specific embodiment
Referring to the accompanying drawing illustrating this utility model embodiment, this utility model is described in more detail.However, this reality
Can be realized in many different forms with new, and the embodiment that should not be construed as by herein proposing is limited.On the contrary, propose
These embodiments are to reach abundant and complete disclosure, and make those skilled in the art understand that this practicality is new completely
The scope of type.In these accompanying drawings, for clarity, may be exaggerated size and the relative size in layer and region.
The seal degree that protection against the tide seeks to realize under -50 ° of c to 85 ° of c ambient temperature is more than ip67, that is, deep at 1 meter
Can not seep water under water.The light fixture module that this utility model provides by the design of the aspects such as sealing structure so as to have anti-
The effect of tide.
With reference to 1-4, this open air protection against the tide light fixture module includes radiator 1, lens 4, LED lamp plate 2, sealing ring 3, and lens 4 set
Put on radiator 1, sealing ring 3 is pressed between lens and radiator, so that it is close to form one between lens 4 and radiator 1
Envelope cavity, LED lamp 2 plate is placed in sealing cavity, and specific LED lamp plate can be fixed on radiator 1 by modes such as screws；Its
In, the compression ratio of described sealing ring is 20% 25%.
In the present embodiment, as shown in Figure 2, lens 4 one side relative with radiator 1 is provided with seal groove 401, close
Sealing groove 401 is along the edge one circle setting of lens 4；Seal groove 401 is adapted with sealing ring, and sealing ring 3 is placed in seal groove 401
Interior, and the part of sealing ring 3 exposes seal groove 401；The sealing ring 3 exposing seal groove 401 is pressed on radiator 1, and produces change
Shape, thus reach the effect of sealing.
In the present embodiment, sealing ring 3 is made using silica gel or fluorubber.Silica gel or fluorubber will not under extremely low temperature
Hardening become fragile, follow the string, undergo no deterioration and aging in the environment of Acidity of Aikalinity and corrosive gas and liquid, therefore
The sealing ring that silica gel and fluorubber support is under -50 ° of c to 85 ° of c ambient temperature and Acidity of Aikalinity and corrosive gas, liquid
In the environment of can keep elasticity constant.From the sealing ring 3 that silica gel or fluorubber are made, this utility model ensure that sealing ring exists
Elasticity under each environment, sealing etc., are capable of moisture seal grade.
In the present embodiment, the section of sealing ring 3 is rounded or oval.Elastomeric material, under mechanical pressure, have
Enough compression ratios, and this compression ratio is relevant with pressure, the section of the sealing ring on existing light fixture module is most of to be in
Semicircle, one side flat shape, so pipe pressure is not much, and pressure cannot be increased by this in flat shape, so sealing ring compression
Rate very little seals it is impossible to be formed, especially in the place that temperature is low, because expanding with heat and contract with cold, elastomeric material meeting shrinkage, and form gap
And leakage；So this utility model is circular or oval o type sealing ring using section, because circular contact and plane between
Area is minimum, and pressure is maximum, and compression ratio is big, and sealing effectiveness is more preferable.
In the present embodiment, the compression ratio being pressed in sealing ring 3 between lens 4 and radiator 1 is 20% 25%.Due to
Sealing ring, under very big pressure, also can produce elastic modelling quantity for a long time and reduce, such sealing effectiveness can reduce it is contemplated that silicon
Up to 750ppm/ DEG C of the line expansion factor of glue or elastomeric material, in the environment of 30 to -50 degree, shrinkage rate is up to 6%, adds 15%
The basic demand of compression ratio, so compression ratio sealing effectiveness in 20-25% is best；This utility model is by the pressure to sealing ring 3
The restriction of shrinkage, thus improve sealing effectiveness, has reached moisture resistant grade；
For example: with reference to Fig. 3-4, the groove depth of seal groove 401 is 1.3mm, a diameter of 2.0mm of sealing ring, exposes in sealing
Sealing ring outside groove is 0.7mm, and after radiator 1 is connected compression sealing with lens 4, the sealing ring being exposed at outside sealing ring is 0.2mm,
The decrement of therefore sealing ring is 0.5mm, and the compression ratio of sealing ring is 25%.
In the present embodiment, face radiator 1 being contacted with sealing ring 3 is plane, in order to ensure sealing effectiveness.
In the present embodiment, linked together by some connectors 5 between radiator 1 and lens 4, and some connectors
5 enclose uniformly along sealing ring one；Because the area of light fixture module is relatively large, this utility model by the connector that is evenly arranged Lai
Uniform pressure is formed to sealing ring it is ensured that the sealing ring uniform force that is pressed between radiator 1 and lens 4, thus favorably
In raising sealing, moisture resistant grade.Wherein, connector 4 to be realized using modes such as screws.
In the present embodiment, the setting of some connectors 5 be located at relative with the set location of sealing ring 3, and sealing ring 3 and
Connector 5 corresponding position is designed to get around the arc structure 301 of connector 5, and arc structure 301 is partial to the interior of light fixture module
Side.The design of arc structure 301 makes sealing ring entirety uniform force, and on holding sealing ring, each section all forms uniform compression
Rate, thus be conducive to improving sealing, moisture resistant grade.
Those skilled in the art should be understood that this utility model can be realized with other concrete forms many and not take off
Spirit or scope from itself.Although having been described for case study on implementation of the present utility model it should be understood that this utility model should not limit
Be made as these embodiments, those skilled in the art can as appended claims define of the present utility model spirit and
Within the scope of make and changing and modifications.
