Abstract
The invention provides a cooling and air supply system for a lamp, belonging to lamps. The system comprises a fan and an air supply pipeline, and is characterized in that the air supply pipeline is one or more of sealed air guide cavities attached to a main body frame of the lamp, partial cavity walls of the air guide cavities are formed by the main body frame, the air guide cavities roughly extend along the inner wall of the main body frame, from top to bottom; an air outlet of the fan is communicated with initial ends of the air guide cavities; tail ends of the air guide cavities run through a space enclosed by a reflect light bowl of the lamp and an insulated transparent plate of the lamp. Since the air guide cavities in the invention are enclosed on the main body frame with a cover plate, the air guide cavities have a big enough cross section which can make air flow to flow smoothly, thus the cooling efficiency is high and the noise is low.
Description
Technical field
The present invention relates to light fixture.
Background technology
The power of stage lamp is all bigger, especially generally reaches the power consumption of multikilowatt with the light fixture of gas-discharge lamp or halogen tungsten lamp as light source, produces a large amount of heats during its work.Traditional radiator structure is by being installed near the fan the light fixture outer surface, and the cold wind of outside is sucked lamp body, through the outside of reflex reflector, forces to discharge the light fixture outside.Because nearer apart with heater herein, motor and fan work environment temperature height easily cause inefficacy, the too high lamp outer casing local melting that also causes of simultaneous temperature, screw skids.
Application number be 200810131481 patent of invention " light source module that is used for lighting apparatus " disclose a kind of generation be used to cool off light source air stream method and be used for the light source module of lighting apparatus, " produce at least one by supply air system and be forced to air stream; this supply air system is positioned at the lighting apparatus housing; this supply air system is connected by at least one pipeline; described pipeline stops at the conduit place, described conduit is along the direction guiding air stream towards light source for it." this invention takes away the heat that light source produces with forced draft, reduced the temperature of light fixture effectively.
Yet, this invents preferred pipeline is pipe, pipe is complicated in the PROCESS FOR TREATMENT in pipeline reducing diameter and knee, and the diameter that its sectional area is less than with it is the square of the length of side, pipe is laid in the light fixture can the many spaces of waste, the stage lamp inner space of computer control is nowadays taken by numerous functional module element, and it is not easy to abdicate enough air supply duct spaces again.
Summary of the invention
The effective way that solves the prior art problem is to develop the gas channel of the metal structure framework of lamp main body frame as supply air system.Thus, the present invention includes fan and air-supply pipeline, the pipeline that it is characterized in that blowing is one or more airtight wind guide chambers that are attached to the main frame of light fixture, and portion's chamber-separating wall of wind guide chamber is made of main frame, and wind guide chamber roughly extends along the main frame inwall from top to bottom; The air outlet of fan is communicated with the top of wind guide chamber; The end of wind guide chamber penetrates into the space that heat insulation light-passing board surrounded of the reflector and the light fixture of light fixture.
As a further improvement on the present invention, there is the fan storehouse at the top of wind guide chamber, and portion's chamber-separating wall in fan storehouse is made of main frame, and the inner chamber in fan storehouse and the profile of fan are suitable, and fan is fixed in the fan storehouse.
As another improvement of the present invention, wind guide chamber and fan respectively have two, and they are arranged in the body frame body left and right sides symmetrically, and the end of two wind guide chambers penetrates into the left and right sides in reflector and space that heat insulation light-passing board surrounds respectively.Perhaps, wind guide chamber, fan storehouse and fan respectively have two, and they are arranged in the body frame body left and right sides symmetrically, and the end of two wind guide chambers is penetrated into the left and right sides in the space that reflector and heat insulation light-passing board surround respectively by both sides.
The present invention is work like this: the high pressure draught that fan forms enters from the top of wind guide chamber, flows downward along wind guide chamber, around the end inflow reflector and bulb of wind guide chamber, discharges through the thermovent of heat abstractor then.
Two arms of common product main frame all are to be bent into the grooved structure by metallic plate, lighter weight is arranged again when making main frame have enough mechanical strengths, the present invention utilizes the metal structure of main frame to add cover plate and forms airtight wind guide chamber to replace the pipe special that lays especially, has the advantage that the tube chamber cross section is big, gas-flow resistance is little, noise is little and cost is low.
The present invention's light fixtures such as stage Computer lamp, Projecting Lamp that suit adopt.
Description of drawings
Fig. 1 is an embodiment of the invention schematic diagram;
Fig. 2 is the cutaway view of the embodiment of the invention.
The specific embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples.
Referring to Fig. 1 and Fig. 2, present embodiment is an Adjustable head lamp, it has the main frame 2 that metallic plate is made, two airtight wind guide chambers 3 that are attached to main frame 2 are arranged on the main frame 2, portion's chamber-separating wall of wind guide chamber 3 is made of main frame 2, and two wind guide chambers 3 roughly extend along the inwall of main frame about 2 two arms respectively from top to bottom; The air outlet of two desk fans 1 is communicated with the top of a wind guide chamber 3 separately; The left and right sides in the space that the reflector 4 that the end of two wind guide chambers 3 penetrates into light fixture respectively and the heat insulation light-passing board 5 of light fixture are surrounded.
All there is a fan storehouse 6 at the top of two wind guide chambers 3, and the profile of the inner chamber in fan storehouse 6 and institute's mounted fan 1 is suitable, and fan 1 embeds in the fan storehouse 6 and the air outlet of fan 1 is communicated with the top of wind guide chamber 3.
Because two arms of common product main frame all are to be formed by the metallic plate bending, have usually
Therefore the cross section of shape can utilize main frame 2 to constitute portion's chamber-separating wall in wind guide chamber 3 and fan storehouse 6, adds wind guide chamber 3 and fan storehouse 6 that upper cover plate 7 makes it to become the square-section simply on main frame 2.
The air-flow that fan 1 forms enters from the top of wind guide chamber 3, flows downward along wind guide chamber 3, from the end inflow reflector 3 and bulb 2 tops of wind guide chamber 3, in seam 8 inflow radiators 9 of reflector 3, discharges around radiator then again.
Other embodiment is not got rid of in the configuration of two wind guide chambers in the present embodiment, according to differences such as the power of light fixture, structures, can dispose one or three, four wind guide chambers in light fixture.
Because wind guide chamber of the present invention is to add upper cover plate 7 to surround on main frame 2, has enough big cross section, makes air current flow smooth and easy, the cooling effectiveness height, noise is little.
