Abstract
The invention provides a spotlight by adopting an LED (Light-Emitting Diode) as light source, which comprises a lens assembly, a light source assembly, a radiating block, a drive assembly, an electric appliance box and an electrode. The light source assembly is arranged on the radiating block and covered in the lens assembly, and the drive assembly is fixed in the electric appliance box, wherein a plurality of radiating ribs and a plurality of inside-and-outside communicated radiating gaps spaced from the radiating ribs are arranged on the back of the radiating block; the electric appliance box is fixedly connected to the radiating block and at least partially surrounded in the plurality of radiating ribs; and the bottom end of the electric appliance box is spaced from the bottom ends of the radiating gaps for a certain distance along the longitudinal axis of the spotlight. Consequently, the heat in the spotlight is directly radiated outside the spotlight via the radiating gaps formed at the spaced distance instead of being bypassed through the bottom end of the electric appliance box and indirectly transmitted to the electric appliance box so that the radiating speed of the heat is increased and a power source drive assembly in the electric appliance box is protected.
Description
Technical field
The present invention relates to a kind of is the light fixture of light source with LED, relates in particular to a kind ofly be more conducive to dispel the heat and the LED shot-light of novel structure, belongs to the LED technical field of semiconductor illumination.
Background technology
Shot-light is the light fixture that is contained in roof, kitchen cabinet top, and it is widely used in the usefulness as accent light such as market, large supermarket, office space, hospital, school, hotel, high-end residential, but both brightening environment can beautify the environment again, be life increasing colour.
The shot-light that generally uses adopts metal halide lamp or fluorescent lamp as light source more at present.The general power consumption of this shot-light is higher, heating is big, lamp tube service life is short, and photochromic soft inadequately, and it is dazzling that the human eye direct-view can be felt, even produce dazzle.
LED(Light Emitting Diode), claim light emitting diode again, they utilize the solid semiconductor chip as luminescent material, when two ends add appropriate voltage, carrier in the semiconductor takes place compound, emits superfluous energy and causes that photo emissions produces visible light.The led light source luminous efficiency is high and monochromaticjty its light is good, spectrum is narrow, need not to filter and can directly send coloured visible light.Under the situation of the same less illuminating effect of power consumption, power consumption is 1/8th of incandescent lamp bulb, 1/2nd of fluorescent tube.Long service life can reach 100,000 hours.Security reliability is strong, and caloric value is low, and non-thermal radiation belongs to cold light source, can safe touch and can accurately control light type and lighting angle, and photochromic soft, the material that free from glare, not mercurous, sodium element etc. may health risks.
Existing LED shot-light has solved the some shortcomings of the shot-light existence of existing use conventional light source, but owing to adopt high-power LED as light source, the low-power LED that its caloric value is more general is big, and long-time the use, temperature in the light fixture increases, cause the inner resistance of LED lamp to become big conversely, in order effectively to reduce the temperature of led light source, need to reduce the thermal resistance of entire product, reduce inner thermal conduction resistance, select the aluminium base of high thermal conductivity coefficient for use, utilize heat conductive pad to reduce thermal contact resistance, optimize the shell radiator, increase available heat exchange area etc., at present, providing effective heat dissipation channel is that LED is used as the important technological problems that the shot-light light source must be considered.
