Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of testing equipment, in particular to an aging test cabinet for blue light chips. Background Art
[0002] There are mainly two forms for existing white LED lamps to emit white light. One is to combine LED chips with different color temperatures together, and white light emission is achieved by adjusting the brightness and ratio of different color LED chips. Usually, a blue light chip, a green light chip and a red light chip are combined to form white light. The other is to use a blue light chip and coat a layer of fluorescent glue layer on the periphery of the blue light chip. After the blue light emitted by the blue light chip passes through the fluorescent glue layer, white light is emitted.
[0003] Before the aging test of the blue light chip and before the blue light chip is not subjected to light mixing treatment, harmful blue light that causes great harm to the human eye will be emitted. For aging tests, the blue light chip is usually placed in an aging test cabinet, the blue light chip is powered on and lit for a long time until the aging degree and service life of the blue light chip are tested. However, the blue light emitted by the blue light chip directly shines out through the perspective window of the aging test cabinet, which will cause harm to the eyes of the operator and is not convenient for the operator to check the status of the blue light chip at any time. Content of the Utility Model
[0004] The purpose of the utility model is to provide an aging test cabinet for blue light chips, which can effectively prevent the blue light emitted by the blue light chip from leaking out of the aging test cabinet.

[0019] The following combines the drawings and embodiments to further describe in detail the specific implementation manner of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.
[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0021] As Figures 1 to 3 shown, an aging test cabinet for a blue light chip according to a preferred embodiment of the present utility model includes a cabinet body 1 and a cabinet door 2. A test chamber 11 is provided inside the cabinet body 1. The cabinet door 2 is connected to the cabinet body 1 and can open and close the test chamber 11. A transparent viewing window 21 is provided on the cabinet door 2. An opening is provided at one end of the test chamber 11 facing the transparent viewing window 21. A foldable blue light blocking curtain 3 is provided on the opening. The blue light blocking curtain 3 includes a first connecting strip 31, a second connecting strip 32, and a fluorescent film 33 connected between the first connecting strip 31 and the second connecting strip 32. The fluorescent film 33 is a yellow fluorescent film 33. The yellow fluorescent film 33 is specifically a colloid containing yellow fluorescent powder, which is an existing material. The first connecting strip 31 is connected to one end of the opening. The second connecting strip 32 is detachably connected to the other end of the opening, and the second connecting strip 32 can be detachably connected to the first connecting strip 31. When the second connecting strip 32 is connected to the other end of the opening, the fluorescent film 33 completely blocks the transparent viewing window 21.
[0022] The utility model is provided with a foldable blue light blocking curtain 3 at the opening of the test chamber 11. Before testing the blue light chip, the second connecting strip 32 on the blue light blocking curtain 3 is connected to the opening, so that the fluorescent film 33 unfolds and blocks the opening, ensuring that the fluorescent film 33 can block the transparent viewing window 21. After the blue light emitted by the blue light chip passes through the yellow fluorescent film 33, yellow light is emitted, avoiding the blue light from penetrating and damaging the human eyes, and facilitating the operator to observe the situation of the blue light chip through the transparent viewing window 21 at any time, which is convenient to use; when the blue light chip is put into or taken out of the test chamber 11 at the opening, the second connecting strip 32 on the blue light blocking curtain 3 is connected to the first connecting strip 31 on the blue light blocking curtain 3, realizing the storage of the blue light blocking curtain 3, facilitating the taking and placing of the blue light chip, and can also be used for testing other color temperature chips.
[0023] Further, N crease lines 331 are arranged in parallel on the fluorescent film 33, and the N crease lines 331 divide the fluorescent film 33 into N + 1 fluorescent glue unit sheets 332. In this way, when the blue light blocking curtain 3 is stored and folded, the fluorescent glue unit sheets 332 are folded along the crease lines 331, which is convenient for folding and storage, and reduces the occupied space after the blue light blocking curtain 3 is folded. Specifically, N is a natural number greater than 0. Specifically, 10 crease lines 331 can be arranged in parallel on the fluorescent film 33, and the 10 crease lines 331 divide the fluorescent film 33 into 11 fluorescent glue unit sheets 332.
[0024] Exemplarily, the widths of the first connecting strip 31 and the second connecting strip 32 are both greater than the width of the fluorescent glue unit sheet 332. After the blue light blocking curtain 3 is folded, the fluorescent film 33 is clamped between the first connecting strip 31 and the second connecting strip 32. In this way, the fluorescent film 33 does not protrude outside the first connecting strip 31 and the second connecting strip 32, avoiding damage to the fluorescent film 33 and ensuring a long service life of the blue light blocking curtain 3.
[0025] Exemplarily, a magnet piece is provided on the second connecting strip 32, and there is a magnet or metal piece on the opening that magnetically attracts the magnet piece, so that the second connecting strip 32 can be conveniently fixed on the opening. Of course, in other embodiments, the second connecting strip 32 can also be detachably connected to the opening.
[0026] Specifically, a magnet or metal piece that magnetically attracts the magnet piece is provided on the first connecting strip 31, which can quickly fix the second connecting strip 32 on the first connecting strip 31 after the fluorescent film 33 is folded; preferably, a magnet that magnetically attracts the magnet piece is provided on the first connecting strip 31, so as to ensure high connection stability between the first connecting strip 31 and the second connecting strip 32.
[0027] In this embodiment, the first connecting strip 31 is connected to the left end of the opening, and the second connecting strip 32 is detachably connected to the right end of the opening, which can facilitate the unfolding and folding of the blue light blocking curtain 3. In another embodiment, the first connecting strip 31 is connected to the upper end of the opening, and the second connecting strip 32 is detachably connected to the lower end of the opening.
[0028] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0029] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
