Description

The infrared ray light projector

The utility model relates to light projector device, especially a kind of infrared ray light projector device.

A kind of infrared ray light projector of patent applied for, it has housing, inlet and outlet is arranged on the housing, its pilum, thermal insulation board, light-operated switch and circuit substrate are fixed in the housing, one Halogen lamp LED is housed in the housing, there is an infrared ray optical filtering in Halogen lamp LED the place ahead, and it is good in establishing that its major defect structurally is that air outlet does not have, and light still can indistinctly be found with rake angle by air outlet; Narrow space in the housing and cause the convenient inadequately and influence in the assembling to ventilate.

The purpose of this utility model provides a kind ofly ventilates better and has the good infrared ray light projector that light leaks that prevents.

The purpose of this utility model is achieved in that the infrared ray light projector, it includes: shell, substrate, optical filtering and closure plate, it is characterized in that: be provided with conduit in the shell, combination rail groove, substrate is a long lath, two microscler limits are protruding with flank and are embedded in combination rail groove, diapire forms the conduit that ventilates in substrate and the shell, conduit has two above ventilating openings, substrate itself also has two above ventilating openings and staggers with ventilating opening on the conduit, the shell two ends element that is positioned is combined with optical filtering and closure plate respectively, and Halogen lamp LED is arranged on the substrate, heat emission fan, transformer and circuit board.

Above-mentioned design, optical filtering are positioned combination of elements at shell one end face, and are positioned at Halogen lamp LED projection end; Closure plate is light tight material, and the combination of elements that is positioned is held in addition at shell, this filtering apparatus, and the light that Halogen lamp LED can be sent is filtered into the infrared ray light that is invisible to the naked eye by the people, and ventilation, shading all have good effect.

Below by drawings and Examples the utility model is described further again.

Fig. 1 the utility model three-dimensional exploded view;

Fig. 2 the utility model master looks schematic diagram;

Fig. 3 the utility model master looks cutaway view;

Fig. 4 is the A-A cutaway view of Fig. 3.

As Fig. 1, shown in 2: the utility model includes: shell 1, substrate 2, optical filtering 3 and closure plate 4, it is characterized in that: be provided with conduit 14 in the shell 1, combination rail groove 16, substrate 2 is a long lath, two microscler limits are protruding with flank 21 and are embedded in combination rail groove 16, substrate 2 forms the conduit 14 that ventilates with shell 1 interior diapire, conduit 14 has two above ventilating openings 15, substrate 2 itself also has two above ventilating openings 22, and stagger with ventilating opening 15 on the conduit 14, the shell 1 two ends element 11 that is positioned is combined with optical filtering 3 and closure plate 4 respectively, and Halogen lamp LED 23 is arranged on the substrate 1, heat emission fan 24, transformer 25 and circuit board 26.1 one-tenth tubulose of shell, its outside is combined with a support 12 with setting elements such as bolt 11, and support 12 is provided with deep-slotted chip breaker 121, and support 12 be an axle with setting element 11, and other can make it turn to be positioned at the setting element 11 that is an angle to establish one on the deep-slotted chip breaker 121 in addition.But shell 1 becomes the checkerwork cell structure with ventilating opening 15, the 22 formula fence of substrate 2.Shell 1 is by metal forming and the C shape groove 13 of one is arranged, and by setting element 31 in conjunction with optical filtering 3 and closure plate 4.

Shown in Fig. 3,4: its optical filtering 3, closure plate 4 and 1 on shell can become closely connected and close, infiltrate or with the combination of leakproof cushion rubber.And still have suitable spacing between substrate 2 bottoms and conduit 14 walls, can ventilate; Circuit board 26 grades are by setting element 27 lockings, and substrate 2 mat flanks 21 and combination rail groove 16 can be extracted out outside the shell, thereby reach the purpose of being convenient to assemble, and optical filtering 3 is bonded to shell 1 one ends with hole 32 and setting element 31; Closure plate 4 is bonded to shell 1 end in addition with hole 42 and setting element 41.This shows that the utility model is not only easy to assembly, and ventilate and anti-light leakage effect good, also guarantee thus service life to prolong.
