Description
Technical field
The utility model relates to a kind of lamp assembly, more particularly, relates to a kind of floodlight device.
Background technology
Traditional light source as incandescent lamp, fluorescent lamp, all gases discharge lamp, all is sphere or cylinder or linear illuminator.In floodlight, often these light sources are arranged in the reflecting surface, make a part of light after the reflecting surface reflection, throw away again.Since light source be 360 ° of spheres or cylinder luminous, no matter which kind of relative angle itself and reflecting surface are and install, some light direct projection of capital is gone out, and scatters out after only the light of some directive reflecting surface is reflected, and is difficult to obtain anticipation ray cast scope and radiation response.And the light that the intense light source direct projection is come out can produce dazzling dazzle, and people's vision can't be adapted to.
Along with development of science and technology, the spot light of illumination level has appearred in recent years, and the most representative is exactly large power semiconductor LED (light emitting diode is called for short LED), and its light emitting source position is almost a point.
After great power LED occurred, though use the size of the lighting of this new light sources to carry out some accommodation, the light fixture that is used for floodlight had still been continued to use the structure of the opening direction of traditional source light transmit direction and reflecting surface.The great power LED floodlight device is continued to use the structure of above-mentioned conventional lamp, has caused many defectives, particularly pollutes in the controlled projection of angle and scope, heat radiation and dazzle to be difficult on three problems solve and take into account.
At first, we learn that from the solid luminescence principle and the basic structure of great power LED light is to send from the non-solid face that covers, and its beam projecting angle is less than or equal to sphere 180 degree, usually all between 110 degree are spent to 130.Thereby the great power LED of this structure is contained in by traditional approach in the reflecting surface of floodlight device, the first, the light that it does not almost send to reflecting surface, thereby areflexia can be sayed; The second, generally within sphere 130 degree, all the opening part direct projection through reflecting surface goes out light fixture, and continues straightline propagation along shooting angle for its main emergent ray, beam angle, and not through reflection.So, continue to use this structure and be difficult to obtain radiation response preferably.
Secondly, the luminous volume of spot light is reduced into a little or is similar to a little, and luminous power and power consumption maintain previous level again, certainly will produce and assemble a large amount of heats during work, if do not derive rapidly, and just can't normal and continuous operation.Especially great power LED with its intrinsic Semiconductor Physics structure, must not tolerate higher operating temperature, and it is again a kind of electronic device of low-voltage and high-current, certainly leads to a large amount of heats under working condition.Therefore in existing fitting structure, can better dispel the heat in order to make great power LED, the root that can only make great power LED be close to reflecting surface is fixed, and the design and the manufacturing of Flood lamps and lanterns caused restriction.
Moreover, more serious problem is: the luminous site size of traditional relatively area source, great power LED can be looked and do a spot light, if its area ratio is 1,000 times, in other words, compare, if still continue to use traditional direct projection mounting structure with the ejaculation luminous flux of same luminous power or equivalent, then the light intensity sent of spot light will exceed 1,000 times of conventional light source, and its dazzle intensity is to big many of the damage ratio conventional light source of vision.Unless the purpose of lighting device design is exactly the special occasions that is used to produce strong dazzle.

3, heat abstractor can be placed on the position of pressing close to spot light most, make the fixed pedestal can be with short distance footpath Derive heat, reduce thermal gradient, improve radiating effect, satisfy the working condition requirement of spot light, guarantee its use Life-span.
4, because emergent ray is to irradiate floodlight device, high power LED device after mixing by reflection again The common deficiencies such as aberration of the hot spot that direct projection light often occurs, Huang Quan, beam center and periphery can be shown Work improves.
5, compare traditional fitting structure, the making of floodlight device of the present utility model there is no difficulty, on the contrary Because having saved the space of reflecting surface, volume can dwindle, and cost can reduce, and designs more flexible and changeable;
7, utilize principle of the present utility model, not only can make the independent floodlight device of single light source, also Can by several such floodlight device combinations, distortion, make the floodlight dress of two or two above light sources Put, to adapt to the needs of bigger projection distance, bigger light projector power.
