Abstract
A lamp structure with a heat dissipation circulating system solves the technical defect of the lamp with structure by the prior art that mosquitoes, dust and the like are adsorbed on an energy-saving lamp or a reflection shield through heat dissipation holes of the lamp during heat dissipation by virtue of heat dissipation holes, which influences lighting of the energy-saving lamp or reflecting of the reflection shield, and forms obvious black spots on the lamp. The adopted technical proposal is as follows: a heat dissipation space is formed between the back of the reflection shield and a metal shell of the lamp, the reflection shield is provided with air circulating holes and an air circulating fan, the air circulating fan forcibly circulates air in the lamp around the reflection shield for heat dissipation by means of the metal shell of the lamp. The lamp structure with the heat dissipation circulating system has the advantages of simple structure and good heat dissipation effect, can keep the interior of the lamp clean, and working state of the heat dissipation system can be automatically controlled when in use according to temperature in the lamp so as to maintain a light source to work under the designed service temperature.
Description
Affiliated technical field
The present invention relates to a kind of fitting structure, particularly a kind of fitting structure that flows and dispel the heat by hot-air in the light fixture by the metal lamp casing with heat dissipation circulating system.
Background technology
Along with the raising of society to energy-conservation requirement, electricity-saving lamp is widely used, and particularly high-power energy saving is widely used in street lamp, outdoor advertising lamp and various Landscape Lightings etc.Such fitting structure is, comprise: the metal lamp casing, reflection shield, Transparent lamp shade and light source, reflection shield is installed in the lamp casing, light source is arranged on diffuser, Transparent lamp shade and lamp casing are tightly connected and constitute illuminator and reflection shield and be sealed in fitting structure in the metal lamp casing, for increasing the luminous efficiency of light source, the reflection shield that in light fixture, is provided with, reflection shield shines out the whole reflections of light that light source is radiated on the reflection shield through Transparent lamp shade, because reflection shield has reflection function, the reflection shield heat conductivility is poor simultaneously, and particularly the glass lamp shade heat dispersion is poorer for Transparent lamp shade, cause the heat of the light source generation that is installed between reflection shield and the Transparent lamp shade to be difficult to distribute, because electricity-saving lamp at high temperature, the not only lost of life, and light efficiency reduces, electricity-saving lamp brightness is reduced greatly, influence result of use.It is to adopt to open louvre on the housing of light fixture that prior art solves the electricity-saving lamp heat dissipation problem, the shortcoming of prior art is, mosquito and dust etc. are adsorbed in louvre enters light fixture on electricity-saving lamp or the reflection shield, and it is luminous or to influence reflection shield reflective to influence electricity-saving lamp, occurs obvious blackspot on light fixture.
Summary of the invention
For overcoming the light fixture of prior art structure, in use, mosquito and dust etc. are adsorbed in louvre enters light fixture on electricity-saving lamp or the reflection shield, it is luminous or to influence reflection shield reflective to influence electricity-saving lamp, the technical deficiency that obvious blackspot on light fixture, occurs, the present invention designs a kind of fitting structure with heat dissipation circulating system, this fitting structure forms air and flows around reflection shield in light fixture, the hot-air of reflection shield front is flowed to the back of reflection shield, and hot-air distributes through the lamp casing conduction in the back of reflection shield.
The present invention realizes that the technical scheme that goal of the invention adopts is, a kind of fitting structure with heat dissipation circulating system, comprise: metal lamp casing, reflection shield, Transparent lamp shade and light source, reflection shield is installed in the lamp casing, light source is arranged in the arc reflection shield, Transparent lamp shade and the housing seal of metal light fixture connect and compose illuminator and reflection shield is sealed in the interior fitting structure of metal lamp casing, form heat-dissipating space between the back of reflection shield and metal lamp casing, reflection shield is provided with air circulation hole and air circulation fan.
The invention has the beneficial effects as follows that simple in structure, good heat dissipation effect keeps clean in the light fixture, during use, can control the duty of cooling system according to the temperature in the light fixture automatically, make light source remain on work under the operating temperature of design.
The present invention is described in detail below in conjunction with accompanying drawing.
Description of drawings
Accompanying drawing 1 is generalized section of the present invention.
Accompanying drawing 2 is an accompanying drawing 1A-A cutaway view.
In the accompanying drawing, 1 reflection shield, 2 metal lamp casings, 3 heat-dissipating spaces, 4 air circulation hole, 5 air circulation fan, 6 outer heat radiation projectioies, 7 heat absorption projectioies, 8 light sources, 9 Transparent lamp shades.
The specific embodiment
Referring to accompanying drawing, a kind of fitting structure with heat dissipation circulating system, comprise: metal lamp casing 2, reflection shield 1, Transparent lamp shade 9 and light source 8, reflection shield 1 is installed in the metal lamp casing 2, light source 8 is arranged in the reflection shield 1, Transparent lamp shade 9 and metal lamp casing 2 are tightly connected and constitute light source 8 and reflection shield 1 and be sealed in fitting structure in the metal lamp casing 2, form heat-dissipating space 3 between the back of reflection shield 1 and the metal lamp casing 2, reflection shield 1 is provided with air circulation hole 4 and air circulation fan 5.
The air that is heated by light source 8 in the cavity of air circulation fan 5 pressures to reflection shield 1 front and Transparent lamp shade 9 formation during use carries out pumping, ventilation, by the air circulation hole on the reflection shield 14 be air in the light fixture around reflection shield 1 circulation, the air of the circulation metal lamp casing 2 of flowing through dispels the heat.
For increasing the radiating effect of metal lamp casing 2, on the interior outside of metal lamp casing 2, be provided with one group of dispel the heat projection 6 and interior heat absorption projection 7 outward.In the heat of the protruding 7 sorption cycle air of heat absorption stream, carry out heat exchange through metal shell 2 and heat radiation projection 6 with atmosphere and realize heat radiation.
For realizing air circulation, fan 5 opens when high temperature or cuts out when low temperature, and air circulation fan 5 is connected with the power supply that light fixture uses through temperature switch circuit.Temperature switch circuit is opened air circulation fan 5 when high temperature, close air circulation fan 5 when low temperature.
Type of the present invention is specially adapted to the light fixture use of light source 8 for the electricity-saving lamp light source.
