Description
Technical field
The present invention relates to a kind of heat abstractor.In addition, the invention still further relates to a kind of luminescence component with heat abstractor of the above-mentioned type.
Background technology
As everyone knows, the LED illumination has irreplaceable advantage, and it saves the energy, super low-power consumption, and the electric light power transfer is near 100%, and identical illumination efficiency is more energy-conservation more than 80% than conventional light source, and its life-span is longer.In view of above advantage, people use LED more and more as light source, for example a large amount of LED remodeling lamps that occur on the market.This LED remodeling light fixture has for example appearance profile of incandescent lamp or fluorescent tube of traditional light source, and it can adapt to existing illuminator better as light source like this.
Yet in the application of some lighting devices, the lighting device with MR/Par lamp has some special annexes usually, for example colored lens, diffusing screen or striped lens and cellular lens.When coming alternative such as MR/Par Halogen lamp LED by LED remodeling lamp, usually following problem can appear: 1) if the length of the length overgauge lamp of LED remodeling lamp so just can not be used to replace the MR/Par Halogen lamp LED; 2) length of lamp is less than the length of standard lamp if LED retrofits, and LED remodeling lamp can be used to replace the MR/Par Halogen lamp LED so, but the temperature of lamp will rise a lot, and light output also can reduce a lot.
Certainly, also can use and have standard-sized LED remodeling lamp and directly replace MR/Par Halogen lamp LED in the lighting device with annex.But the temperature of LED can rise much equally, and this can reduce the life-span and the light output of lamp.This is because the annex of lighting device has stopped the heat abstractor ambient air at LED remodeling lamp to flow, and has influenced the heat dissipation of heat abstractor.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of heat abstractor that is used for luminescence component, this heat abstractor itself is integrated with the mechanism that is used for fixing additional optical accessory, thereby can be applied to have the luminescence component of this heat abstractor well, substituting the light source of luminescence component without a doubt, and radiating effect there is not harmful effect.In addition, also allow under the prerequisite of the structure that does not change luminescence component, to substitute the light source of luminescence component according to heat abstractor of the present invention.In addition, the invention allows for a kind of luminescence component with heat abstractor of the above-mentioned type.
First purpose of the present invention realizes thus by a kind of heat abstractor of luminescence component, promptly this heat abstractor comprises the housing with light-emitting window, in housing, be provided with the led light source of luminescence component and on the light exit direction, be arranged on the lens or the reflector in led light source downstream, wherein, heat abstractor also has the optical accessory maintaining body that removably is fixed on the housing wall that limits light-emitting window, is used on the light exit direction other optical accessory being fixed on the downstream of lens or reflector.In design of the present invention, the other optical accessory of the optical effect that is used to provide additional can integrate by the optical accessory maintaining body and the heat abstractor of heat abstractor, has so just cancelled the set for this purpose optical accessory of luminescence component of using this heat abstractor.Therefore also just eliminated these and be arranged on optical accessory on the luminescence component originally heat abstractor, and then to the influence of the installation site of the luminescence component of having used this heat abstractor, also eliminated simultaneously these optical accessories blocking to heat abstractor, thereby avoided optical accessory to blocking that the heat abstractor ambient air flows, this has improved the heat dispersion of heat abstractor significantly.
Preferably, the optical accessory maintaining body comprises retaining ring.This retaining ring is used for other optical accessory is fixed on the light-emitting window of heat abstractor.
Further preferably, be formed with groove on the excircle of retaining ring, and on the housing wall that limits light-emitting window, be formed with projection with the groove lock fit, perhaps be formed with projection on the excircle of retaining ring, and limiting the groove that is formed with on the housing wall of light-emitting window with protruding lock fit.On retaining ring, settle after the other optical accessory, projection is slided in the groove, thereby make retaining ring and then be fixed on the heat abstractor by the other optical accessory that retaining ring limits by the rotation retaining ring.
Optionally, be formed with screw thread on the excircle of retaining ring, be used for being screwed into the screw thread that is formed on the correspondence on the housing wall that limits light-emitting window.This can realize retaining ring equally so that the other optical accessory that limits by retaining ring and heat abstractor between fixedly connected reliably.
Preferably, the optical accessory maintaining body also comprises the light shield that is formed on the retaining ring.Propose according to the present invention, light shield has cylindrical, the cylindrical or flaring profile of cutting sth. askew.Optionally, light shield comprises the anti-dazzling screen on a plurality of circumference that are distributed in retaining ring.Certainly, light shield also can have the profile of other types.
Another object of the present invention realizes that by a kind of luminescence component this luminescence component comprises the heat abstractor of the above-mentioned type, and luminescence component according to the present invention is preferably designed to LED remodeling lamp.This LED remodeling lamp can substitute the light source of luminescence component without a doubt, and radiating effect is not had harmful effect.
Preferably, LED remodeling lamp also comprises: led light source; On the light exit direction, be arranged on the lens or the reflector in led light source downstream; Driver and other optical accessory, wherein, the housing of heat abstractor is separated into first cavity that holds led light source and lens or reflector and second cavity that holds driver, and wherein, other optical accessory is fixed on the light-emitting window place by described optical accessory maintaining body.Thus, the other optical accessory of the optical effect that is used to provide additional can integrate by the optical accessory maintaining body and the heat abstractor of heat abstractor, has so just cancelled the set for this purpose optical accessory of luminescence component of using this heat abstractor.Therefore also just eliminated these and be arranged on optical accessory on the luminescence component originally heat abstractor, and then to the influence of the installation site of the luminescence component of having used this heat abstractor, also eliminated simultaneously these optical accessories blocking to heat abstractor, thereby avoided optical accessory to blocking that the heat abstractor ambient air flows, this has improved the heat dispersion of luminescence component significantly.
Preferably, other optical accessory is a kind of in colored lens, diffusing screen or striped lens and the cellular lens.
