Abstract
A lamp structure with radiating circulation system solves the technical weaknesses that a lamp in the prior art adopts radiating holes to dissipate heat, mosquitoes and dust can enter into the lamp through the radiating holes and attach to an energy-saving lamp or a reflector, thereby affecting the luminescence of the energy-saving lamp and the reflection of the reflector, and generating obvious black spots on the lamp. The technical scheme is that a radiating space is formed between the back of a reflector and a metal lamp shell, air circulating holes and an air circulating fan are arranged on the reflector, the air circulating fan can force air in the lamp to circulate around the reflector, and heat is dissipated through the metal lamp shell. The lamp structure has the advantages of simple structure and excellent radiation effect, keeps the inner portion of the lamp clean, can automatically control the working state of a radiating system according to the temperature in the lamp when in use, and lead a light source to work under the designed working temperature.
Description
Affiliated technical field
The utility model relates to a kind of fitting structure with heat dissipation circulating system, particularly a kind of fitting structure that flows and dispelled the heat by the metal lamp casing by hot-air in the light fixture.
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, a kind of fitting structure of the utility model design 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 utility model 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 beneficial effects of the utility model are, and are simple in structure, and 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.
Below in conjunction with accompanying drawing the utility model is elaborated.
Description of drawings
Accompanying drawing 1 is the utility model generalized section.
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.
The utility model is specially adapted to the light fixture use of light source 8 for the electricity-saving lamp light source.
