Xenon lamp

This creation is about the technical field of lighting, especially a xenon lamp with small volume, light weight, high heat dissipation efficiency, high output wattage light source and no glare.

Based on the reasons for energy saving and carbon reduction, the current lamp source uses a light-emitting diode. The light-emitting form of the xenon lamp is roughly divided into two types, one is a direct-emitting xenon lamp, and the other is a diffuser-type xenon lamp.

The xenon lamp using the light-emitting diode base as a light source can achieve energy-saving effect, but the process of driving the light-emitting diode to perform electro-optical conversion generates waste heat. The accumulation of waste heat reduces the life of the lamp source of the xenon lamp or the drive circuit of the xenon lamp.

In the direct light-emitting xenon lamp, there is an advantage in that higher illumination can be provided, but since the direct light-emitting xenon lamp does not easily change the setting angle of the light source. Therefore, such a xenon lamp is liable to cause glare. In addition, the waste heat generated by the direct-exit xenon lamp can be dissipated through the open lamp cup, but the heat dissipation efficiency is limited.

In the diffuser type xenon lamp, in order to solve the problem of the glare phenomenon, a diffuser is additionally added to allow the light source of the light emitting diode to have a soft light effect, which can reduce the glare phenomenon; On the one hand, the problem of waste heat, due to the inability to discharge properly, will aggravate the impact of the waste heat problem.

In view of this, the present author proposes a xenon lamp to solve the lack of the prior art.

A first group of light sources of the light emitting diodes can be emitted to the reflective cup.

A third object of the present invention is to provide the above-described xenon lamp, comprising a fixing frame that fixes the reflecting cup so that the thermal energy can dissipate the thermal energy by the fixing frame.

The fifth object of the present invention provides the above-mentioned xenon lamp, comprising a heat dissipating sleeve, which is combined with the heat dissipating sleeve to achieve high efficiency heat dissipation.

The sixth object of the present invention provides the xenon lamp described above, wherein the insulating heat dissipating gel is filled in a gap between the heat dissipating sleeve and the reflecting cup to achieve high efficiency heat dissipation.

Compared with the prior art, the present invention provides a lamp, which uses a principle of secondary optics to reflect a first group of light sources generated by an illuminant into a second group of light sources to solve the traditional xenon lamp by using a diffusion sheet. Or the light emitted directly from the light-emitting diode causes a problem of glare loss and accumulation of waste heat.
