Description
Technical field
The present invention relates to a kind of LED car lamp, the LED car lamp that especially a kind of radiator local is exposed.
Background technology
Along with the development of science and technology, light efficiency is high, after life-span long LED enters lighting field, high-power LED is also applied in automotive lamp in plan by various enterprise and research institution, but because LED is semiconductor electronic component, its principle of luminosity is very not identical with conventional light source with the characteristic of self, the temperature during work of such as Halogen lamp LED and xenon lamp is very high and very heat-resisting, and temperature during LED work is lower and To Be Protected from Heat, its chip temperature is generally no more than 100 degree, and the operating temperature of LED often raises 10 degree, its light decay life-span about shortens half, light efficiency about reduces by 3%, existing LED car lamp is in order to solve the problem of heat radiation, car light is designed to expose LED car lamp completely, to be exposed completely by several radiating fins exactly, but the LED group be arranged between two radiating fins also exposes completely, easily make the efficiency of the dirty reduction bright dipping of LED lamp bead, lamp pearl there is electrode inconvenience water to clean simultaneously, and LED light source is chronically exposed in air, easily cause electric pole short circuit and oxide etch, the service life of LED car lamp is significantly shortened.
Summary of the invention
For the problems referred to above of the prior art, the present invention proposes the LED car lamp that a kind of radiator local is exposed, the invention solves LED car lamp heat radiation, LED lamp bead is easily dirty, be inconvenient to clean, cause the light extraction efficiency of LED lamp bead low, the technical problem of the easy short circuit of electrode and oxide etch.
Technical scheme of the present invention is: the LED car lamp that radiator local is exposed, comprise radiating bottom plate, described radiating bottom plate is provided with some radiating fins, described radiating bottom plate is at least provided with a LED group installation cavity and LED group installation cavity is embedded in some radiating fins, LED group to be arranged on radiating bottom plate and to be positioned at LED group installation cavity, and the exiting surface of described LED group installation cavity is at least provided with a slice transparent glasses lens.
Further, described radiating bottom plate is provided with a LED group installation cavity, and the exiting surface of described LED group installation cavity is provided with a slice transparent glasses lens.
Further, described radiating bottom plate is provided with two LED group installation cavitys, and the exiting surface of described two LED group installation cavitys is separately installed with a slice transparent glasses lens.
Further, described radiating fin laterally can be uniformly distributed, be longitudinally uniformly distributed, staggered be uniformly distributed or annular spread on radiating bottom plate.
Further, described LED group be in single large-power LED light bead or some, low-power LED lamp pearl.
Further, described transparent glasses lens is glass or safety glass or transparent plastic.
Compared with prior art, the invention has the beneficial effects as follows:
1. the present invention is by be arranged on LED group on radiating bottom plate and to be arranged in LED group installation cavity, and on radiating bottom plate, be provided with some radiating fins exposed, first the caloric value of LED group is directly delivered on radiating bottom plate, be delivered on some radiating fins exposed by radiating bottom plate again, heat is delivered in air by the large-area radiating fin exposed, then is taken away by heat with the air of flowing; Ensure that the heat sinking function that car light is good thus, add the light decay life-span of LED group, ensure that the reliability of automotive lamp product.
2. the present invention is provided with transparent glasses lens on the exiting surface of LED group installation cavity; for the protection of the LED group in car light; the area of transparent glasses lens is less; only block the radiating surface of sub-fraction radiating fin; very little on the heat radiation impact of whole lamp; but arranging of transparent glasses lens can avoid LED group by the pollution such as dust and sewage, effectively prevent electrode in LED group to be short-circuited and oxidized situation, ensure that the light extraction efficiency of car light and the reliability of car light and service life.
