Description

Technical Field

[0001] The utility model relates to the technical field of lighting structures for ovens, in particular to an LED light source system and an oven. Background Art

[0002] Halogen lamps are commonly used for internal lighting in high-temperature environments such as ovens. However, their brightness is gradually failing to meet market demand, and they also suffer from high energy consumption. Therefore, LED lamps have begun to be used as replacements. For example, Chinese Patent Application Publication No. CN 110185999 A discloses an oven lighting device. The lighting device comprises a metal shell or oven lamp cover mounted on an opening in the inner wall of the oven's baking chamber, a lens positioned within the oven's baking chamber and connected to the metal shell, and an LED light module positioned on the outer wall of the oven, opposite the metal shell or oven lamp cover. The LED light module comprises a heat sink for dissipating heat from the light source, an LED light source mounted on the heat sink, and a focusing lens covering the LED light source. This device addresses the technical issues of LED lamps used in ovens in the prior art, such as low LED luminous efficiency, complex structures, large size, heavy weight, and significant light loss. In actual operation, despite the heat sink, the LED light source is relatively close to the oven's baking chamber, which shortens its service life due to the influence of the oven's baking chamber. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides an LED light source system, which solves the problem in the prior art that the LED light source is too close to the oven baking chamber and is affected by the oven baking chamber, which shortens the service life of the LED light source.

[0004] According to an embodiment of the present invention, an LED light source system includes an LED light source, a light guide component connected to the LED light source, and a reflector connected to the light guide component, wherein the reflector has an opening on one side and the opening is covered with an illumination glass, wherein the LED light source is connected to a power connection wire for supplying power to it, and after the LED light source is energized and emits light, it passes through the light guide component to the reflector, and then is emitted outward through the illumination glass.

[0005] In the above embodiment, the LED light source is at a longer distance from the location where light is emitted (i.e., the reflector), so the impact of temperature on the LED light source is correspondingly reduced, and the service life is also improved. This solves the problem in the prior art that the LED light source is too close to the oven baking chamber and is affected by the oven baking chamber, which shortens the service life of the LED light source.

[0006] Furthermore, the light guide assembly includes a light guide column, one end of which is connected to the LED light source and the other end of which is fixedly extended into the reflector.

[0007] Furthermore, a temperature-resistant layer is provided around the light guide column.

[0008] Furthermore, a heat sink is connected to the LED light source.

[0009] Furthermore, the reflector is provided with a first clamp located on one side of the opening and a first connecting plate located on the other side of the opening. The first connecting plate is also detachably connected to the second clamp, and the two sides of the illuminated glass are respectively clamped to the first clamp and the second clamp.

[0010] Furthermore, a second connecting plate is provided on the second clamping member, and the second connecting plate and the first connecting plate are connected by bolts.

[0011] Furthermore, it also includes a light shield covering the outside of the heat-resistant layer.

[0012] Furthermore, a third clamping component is provided in the light shield and is clamped with the temperature-resistant layer.

[0013] According to an embodiment, an oven is also provided, which includes an outer shell, a baking chamber is arranged in the outer shell, and also includes the above-mentioned LED light source system, a mounting hole is opened on the outer shell, a reflector is installed at the mounting hole and extends outside the outer shell, the illumination glass covers the side of the mounting hole facing the baking chamber, the LED light source is located outside the outer shell, and the light shield is fixed to the outer wall of the outer shell.

[0014] Furthermore, the cross section of the light shield is U-shaped, and a connecting ear is provided extending inwardly, and the connecting ear is mounted on the outer shell by screws.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The reflector is the light-emitting point. After the LED light source emits light, it passes through the light guide component into the light-emitting cover, and then radiates outward through the illumination glass to achieve lighting. This has the effect of keeping the LED light source away from the illumination point. Therefore, the influence of the temperature near the illumination point on the LED light source will be correspondingly reduced, and the service life will be improved. This solves the problem in the prior art that the LED light source is close to the oven baking chamber and is affected by the oven baking chamber, which shortens the service life of the LED light source.
