Kinds Of Automotive Lamps
Automotive lamps which includes a lamp body, a gasket disposed between the lamp
body and an automobile body panel for sealing a back side of the lamp, a seal leg projecting from the lamp body for attaching thereto the gasket, wherein the foamed gasket is molded integrally with a tip end part of the seal leg. The present invention relates to an automotive lamp in which a gasket for sealing a back side of the lamp is disposed between a lamp body and an automobile body panel so that water, dusts and the like are prevented from entering the back side of the lamp where wires connecting to a lamp bulb or the other electrical equipment are arranged."A good fog lamp produces a wide, bar-shaped beam of light with a sharp horizontal cutoff," according to Daniel Stern, a consultant in the field of automotive lighting science, technology and regulation. Many factory-installed, dealer-optional and even aftermarket fog lamps fail to meet this standard. This happens when the color of the fog lamp light fails to match the legal standard and when the orientation of the fog lamp is incorrect.Drivers turn on car fog lamps when weather conditions are bad and they need help seeing the area immediately ahead of the vehicle, the painted lane markings and the sides of the road. Unfortunately, what many drivers get from their fog lamps are beams of light too small to make a difference, except in producing glare that disrupts the vision of oncoming drivers.
The present invention was made in view of the foregoing difficulties and problems accompanying the conventional automotive lamps . Therefore, an object of the present invention is to provide an automotive lamp capable of simplifying coupling operation during assembly as well as improving the yield rate of materials for a gasket which is disposed between a seal leg and an automobile body panel.
The above and other objects can be achieved by a provision of an automotive lamp which, according to the invention, includes a lamp body, a gasket disposed between the lamp body and an automobile body panel for sealing a back side of the lamp, a seal leg projecting from the lamp body for attaching thereto the gasket, wherein the foamed gasket is molded integrally with a tip end part of the seal leg. Since the gasket is foam-molded integrally with the seal leg projecting from the lamp body and thereby in close-contact with the seal leg, it is not necessary to adhere the gasket to the seal leg by an adhesive agent or the like.
Good fog lamps follow relevant legal standards and use bulbs that produce white or selective yellow light. When blue light is subtracted from white light, the result is selective yellow, or a true yellow. Unfortunately, in the automotive industry, light other than white is often considered white. For example, fog lamps frequently contain blue high-intensity discharge (HID) lights and brown-sealed beams, even though their light is not white. Other fog Automotive leds transmit yellow-tinged rather than white light.
Blue light makes bad weather even harder to overcome. It causes a glare for drivers who face cars emitting blue-tinged light. There is some evidence that yellow fog lamps are best because of the physics of the interaction of the eye with the wavelengths of the different colors of light. Fog lamps should not transmit light other than white and selective yellow.
According to another aspect of the present invention, first, a nozzle injects a material for a foamed gasket into a gasket molding groove formed in a jig, and the injected material is left to thereby foam-expand. Next, a lamp body with a seal leg facing down is operated to move downward so that the seal leg is inserted in the molding groove, and the seal leg is held against the gasket material. As a result, the surface of the gasket is solidified. Afterwards, the gasket is released from the jig together with the lamp body and the seal leg, and the gasket is left in atmosphere so that the gasket is sufficiently solidified. Thus, the gasket is molded integrally with the seal leg.
Among these steps, if desired, the step in which the nozzle injects the gasket material, the step in which the automotive halogen lamps body is moved down to press-fit the seal leg into the foamed gasket material filled in the molding groove, and the step in which the lamp body is lifted to release the gasket from the molding groove together with the seal leg may be automated. If these steps are automated, an operator has to merely set the lamp body on an automation line and take the lamp body which is molded integrally with the gasket out of the automated product line. Hence, mass-production can be achieved while excessively reducing the manual works.
Further, if the seal leg is subjected to surface active treatment, the gasket would hardly detach from the seal leg because of the high adhesibility of the foamed gasket to the seal leg. As a result, easy treatment of the lamp with which the gasket is integrated, improved operation for coupling the lamp to the vehicle body, and good workability when the gasket is provided can be accomplished. To convert white fog lamps to selective yellow, you can order selective yellow bulbs or apply a coating. Applying a coating is less expensive. Before applying the coating, remove the lamps and clean the lenses. If the lamps have removable lenses, spray their interior rather than exterior surfaces. Use several coats of a transparent yellow paint with good adhesion and durability. Keep coats thin enough so the surface is wet but not running. Let each coat become almost dry before applying another. Add additional coats until the selective yellow tint is about two shades darker than you envisioned. Let the lens coatings dry and harden before taking the car on the road.
When used with headlights, good fog automotive HID kits help direct the overall beam of light toward the area immediately in front of the vehicle, overcoming some of the vision lost when headlights cause glare from fog, rain or snow. When used without headlights, good fog lamps illuminate the area immediately in front of the vehicle, and at the sides of the road, enough for you to drive safely at reduced speed.
If you drive in conditions bad enough to call for fog lamps without headlights, be sure your fog lamps are good. Check their aim. And slow down.
Turn off fog lamps when conditions are clear. If left on, they provide too much light in the foreground, reducing distance vision. They also contribute create a glare for oncoming drivers.
