Abstract
The utility model discloses an ultra-thin light-emitting diode (LED) project lamp capable of dissipating heat efficiently. The ultra-thin LED project lamp comprises a shell body and a cover plate. An electronic assembly, a luminous chip, and a reflecting shade are arranged inside the shell body, and the electronic assembly and the lighting chip are distributed on the bottom portion of the shell body crosswise. The ultra-thin LED project lamp is characterized in that a heat dissipation metal plate is arranged below the reflecting shade and the luminous chip, and the dissipation metal plate is fixed on the bottom portion of the shell body. The heat dissipation metal plate and the bottom portion of the shell body contact in large area in a heat-conducting mode. The ultra-thin LED project lamp capable of dissipating the heat efficiently can quickly and evenly dissipate the heat.
Description
Technical field
The utility model relates to a kind of ultra-thin LED Projecting Lamp of high efficiency and heat radiation.
Background technology
Tradition LED Projecting Lamp generally comprises housing and cover plate, cover plate comprises framework and transparent panel, be provided with electronics assembly, luminescence chip and reflection shield in the housing, wherein the electronics assembly generally is in luminescence chip and reflection shield rear, therefore the thickness of traditional Projecting Lamp is generally bigger, and the bright dress of this Projecting Lamp is just attractive in appearance inadequately when using.If the reflection shield of Projecting Lamp and luminescence chip and electronics assembly branch are arranged, thickness can reduce so, but the thing followed is exactly heat dissipation problem, thinner Projecting Lamp does not have condition to do very thick housing base plate and vent rib, heat is directly transferred to housing bottom, be easy to cause heat too to concentrate and can't high efficiency and heat radiation, also concentrate because of heat easily and produce high temperature, and then cause security incident.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of ultra-thin LED Projecting Lamp of high efficiency and heat radiation of Homogeneouslly-radiating fast.
For this reason, the ultra-thin LED Projecting Lamp of the high efficiency and heat radiation that the utility model provides, comprise housing and cover plate, be provided with electronics assembly, luminescence chip and reflection shield in the housing, described housing bottom cross direction profiles has electronics assembly and luminescence chip, described reflection shield and luminescence chip below are provided with heat-dissipating metal sheet, and heat-dissipating metal sheet is fixed in housing bottom, and described heat-dissipating metal sheet contacts with the heat conduction of housing bottom large tracts of land.
Increase below improvement of the present utility model is further specified effect: traditional light fixture is in order to realize good heat radiating, need be with housing bottom and thickening all around, with material many, the cost height, moreover the utility model product is a kind of ultra-thin LED Projecting Lamp, thickness own is limited, does not have condition to do above-mentioned radiating treatment.Heat center in the utility model below the luminescence chip is thickeied by heat-dissipating metal sheet, thereby with lower cost, realized better radiating effect, adopt thicker material at this heat sink, but area is less, with less material the heat of led module is delivered to housing bottom equably with less thermal resistance, play the effect of high efficiency heat conduction, and drain pan adopts thinner aluminium stretching sheet material and contact with the heat-dissipating metal sheet large tracts of land, realization obtains the purpose of bigger area of dissipation with less material, be conducive to heat radiation and convection current, can solve the heat dissipation problem of ultra-thin LED Projecting Lamp preferably.
Description of drawings
The split structural representation of the ultra-thin LED Projecting Lamp of the high efficiency and heat radiation that Fig. 1 provides for the utility model.
The specific embodiment
As shown in the figure, the ultra-thin LED Projecting Lamp of the high efficiency and heat radiation that the utility model provides, comprise housing 1 and cover plate 2, be provided with electronics assembly 3, luminescence chip 4 and reflection shield 5 in the housing 1, described housing 1 bottom transverse is distributed with electronics assembly 3 and luminescence chip 4, described reflection shield 5 and luminescence chip 4 belows are provided with heat-dissipating metal sheet 6, heat-dissipating metal sheet 6 is aluminium sheet, heat-dissipating metal sheet 6 is fixed in housing 1 bottom, described heat-dissipating metal sheet 6 contacts with housing 1 bottom large tracts of land heat conduction, and concrete operations are provided with the heat-conducting silicone grease layer exactly between heat-dissipating metal sheet 6 and housing 1 bottom.In the present embodiment, offer first screwing through hole 7 on the heat-dissipating metal sheet 6, described housing 1 bottom offers second screwing through hole 8, offer the 3rd screwing through hole 9 on described luminescence chip 4 upper plates, bolt 10 passes the 3rd screw 9 through holes, first screwing through hole 7 and second screwing through hole 8 and realizes interfixing of luminescence chip 4, heat-dissipating metal sheet 6 and housing 1 bottom.
