Abstract
The utility model provides a heat insulation ceiling lamp which comprises a shell body and a lamp holder, wherein the lamp holder is arranged in the shell body and is used for installing a bulb. The shell body comprises a tube shade and a flange positioned below the tube shade and connected with the tube shade. The heat insulation ceiling lamp further comprises heat insulation materials attached onto the tube shade and/or the flange. As the heat insulation materials are arranged in the heat insulation ceiling lamp, when generated inside the lamp, the heat is blocked so as not to be transferred to the outer surface of the lamp; and as the insulation materials attached onto the tube shade and/or the flange play a role of heat insulation, the temperature on the outer surface of the ceiling lamp can be kept in a lower-temperature state, so that the safe use environment of the lamp is ensured, and the safe design and installation requirements for the lamp is met.
Description
[technical field]
The utility model relates to lighting field, refers in particular to a kind of smallpox light fixture with heat-proof quality that embeds ceiling.
[background technology]
Modern interior Design finishing or occasions such as lighting of home, office lighting generally can be used embedded smallpox light fixture; The modal application of embedded smallpox light fixture is mounted in the perforate of having offered on the ceiling; The ceiling of ceiling system much all is common combustible material; Like wooden and plastics etc., if embedded smallpox light fixture is installed on ceiling, the bulb in the light fixture is because the too high ceiling of lighting probably of temperature.In addition, the tube cover of light fixture is embedded in the space behind the ceiling, and this space behind ceiling generally also can be provided with some building thermal insulation materials; Like glass fibre, ceramic fibre, alumina silicate etc.; As shown in Figure 1, the tube that these building thermal insulation materials 100 cover light fixture covers all around and top, makes that the heat-dissipating space around the light fixture is not enough; Particularly be equipped with under the situation of graininess fire-proof heat-insulating material, these graininess fire-proof heat-insulating materials can be filled the space around the light fixture comparatively tight, do not stop enough heat-dissipating spaces around the light fixture; Therefore the long-pending heat around the recessed light fixture is more and heat radiation is difficult, overheatedly easily causes short circuit, has disaster hidden-trouble.Special light fixture sometimes can be installed in the position of adjacent wooden frame 200, or is installed in the position near other combustibles, thereby these combustibles around the light fixture are being ignited through drying fully very easily behind the long high temperature.And after light fixture is stopped using a period of time; Tube face can gather maybe also maybe be from inflammable foreign material such as the dust below the smallpox, hair, cobweb and cooking fats from smallpox top; When reusing; Other combustibles around objects such as the dust of tube face can burn and ignite, very dangerous.Current a kind of settling mode is that a big can is set in ceiling, and light fixture is seated in the can, props up a space through this can at the light fixture peripheral branch, prevents high temperature light fixture contact combustibles and the breaking out of fire of igniting.It is bigger that but this structure takes up room, and can is bulky, complex structure, and difficult installation, manufacturing cost and installation cost are too high, and can itself also lacks heat-dissipating space with its tight contact of combustibles all around.Existing in addition for non-fire resistant lighting fitting; Can be employed in the space of light fixture top setting up the mode in space and increase around the light fixture dispels the heat; But such mode takes up room too big, thereby and the thickness that has reduced insulating materials reduce the insulation effect of insulating materials greatly.
Also having some settling modes is that perforate is set on recessed light fixture; Reach the heat radiation purpose through these perforates, but these perforate meetings and are ignited when lamp temperatures is higher because of the gathering of combustibles such as dust, hair; There is bigger potential safety hazard; And indoor useful air can be lost to the external world through the perforate of light fixture, influences the effect of indoor constant temperature system, also influences the soundproof effect of light fixture.
Also have some embedded fire resistant lighting fittings, in lamp casing or outside be provided with fire proofing material, and housing is provided with louvre, reaches the heat radiation purpose through louvre, but the burning things which may cause a fire disaster in the light fixture can be from louvre the combustibles around the light fixture of igniting of leaping up out.And fire proofing material is that the high temperature (Baidu to thousands of degree in full) when fire is taken place is heat insulation, can not satisfy heat insulation requirement to lower temperature, often causes the lamp casing temperature too high.And fire proofing material needs multi-disc to apply ointment or plaster, and unavoidably the slit can occur, is difficult to guarantee effect of heat insulation.In addition, make light fixture overheated, cause short-circuit fire thereby the outer covering insulating material of light fixture can seal thermovent.Therefore the embedded fire resistant lighting fitting of this kind can only be installed on the fire proofing material, if be installed on the combustible material or neighbouringly then have than potential safety hazard greatly.
It is conventionally believed that the embedded smallpox light fixture with fire-proof function is the place that can be installed on the combustible or combustible is arranged on every side; This is a misunderstanding in fact; The lamp surface temperature is often in 120 deg.c or higher when fire resistant lighting fitting uses based on halogen bulb, and combustibles on every side easily ignite.And often offer louvre on the flameproof enclosure of fire resistant lighting fitting, the combustibles around can igniting through louvre if hair on the based on halogen bulb or foreign material burn.Some countries are very high to the temperature requirement of recessed light fixture; Formulated relevant criterion; For example concrete mark and symbol have been set in the several criteria the inside; Indicate that the light fixture that reaches product standard without test not directly is installed on the flammable ceiling in surface (as shown in Figure 2), and light fixture cladding material (as shown in Figure 3) not directly.And according to product standard EN60598.1 and EN60598.2, the light fixture operating temperature is limited, the heat test during these light fixtures process duties, the surface temperature of regulation light fixture normal running can not surpass 90 degree.If the temperature of smallpox light fixture tube cover outer surface surpasses 90 (5 degrees centigrade tolerance can be arranged), just can not be installed on the common flammable ceiling.After insulating materials was gone up in the light fixture covering, situation more worsened, and the temperature of lamp surface can be much higher, and there is the multiple hidden danger that causes fire in existing fire resistant lighting fitting.In view of the above, existing smallpox light fixture operating temperature is all too high, fails to satisfy the requirement of this standard.Though some fire resistant lighting fitting can be provided with the purpose that fire proofing material reaches fire-proof and thermal-insulation; But the fire-proof and thermal-insulation when this purpose is meant breaking out of fire; Be not to be provided with, and test finds that such structure does not reach the requirement that temperature is lower than 90 degree yet, and cover very difficulty of laminated material at lamp surface in order to satisfy the requirement that the lamp surface temperature is lower than 90 degree; Because fire proofing material all is a sheet generally, need cutting and nothing to meet applying.For some for example Britain, Denmark etc. of some countries of Europe; Requirement to the smallpox light fixture also not merely only is the fire protecting performance aspect; But more be the security performance of light fixture, and higher to the lamp surface temperature requirement, the requirement that fire proofing material can not satisfy lamp surface low temperature simply is set.
Therefore, provide lower, the safe and reliable smallpox light fixture of a kind of surface temperature real for necessary.
