Although it can remind the user that the life of the bulb will end soon, the user cannot know how many days the remaining life of the light bulb in the projector can allow the user to use. It can only be known that the lamp in the projector will soon be unusable, but not the number of days that the user can still use it according to the user's usage habits.

Embodiment Construction
[0018] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.
[0019] Such as figure 1 As shown, it is a flowchart of a method for estimating the lifetime of a bulb in a preferred embodiment of the present invention. The method is used for a projector with a bulb light source. The projector generally includes a light source. In the present invention, the light source of the projector is Bulbs, but the bulbs generally have a certain service life, so the projector needs to replace the bulbs in time to ensure the normal use of the projector. The method provided by the invention can remind the user of the usage of the light bulb in real time, so as to facilitate the user to replace the light bulb in the projector in time. In this embodiment, the method includes:
[0020] Step S101, record the starting working date of the light bulb...

The invention provides an estimation method for the service life of a bulb. The estimation method for the service life of the bulb is applied to a projector with a bulb light source. The estimation method for the service life of the bulb comprises the steps of (1) recording the initial working date of the bulb, wherein the bulb has the working life; (2) accumulating the working time of the bulb to determine the usage mode of the bulb in the preset period; (3) calculating the estimated service life of the bulb according to the working life of the bulb and the usage mode of the bulb; (4) calculating the service life end date of the bulb according to the estimated service life and the initial working date of the bulb; (5) outputting the service life end date at a preset reminding time before the service life end date. Therefore, a user can learn about the service life end date of the bulb in the projector in real time through the estimation method for the service life of the bulb.
Description
technical field [0001] The invention relates to the field of projectors, in particular to a method for estimating the lifetime of a bulb in a projector. Background technique [0002] At present, the lifespan of the lamp in the projector is relatively short, and the user usually needs to replace it in time, so the user needs to know when to replace the lamp in the projector. [0003] In the prior art, the projector only reminds the user to replace the light bulb when the light bulb is near the end of its life. For example, when the life of the bulb is 500 hours or less, a warning window pops up to remind the user to replace the new lamp. Although this can remind the user that the life of the bulb will end soon, the user cannot know how many days the remaining life of the light bulb in the projector can allow the user to use it. It can only be known that the light bulb in the projector is about to be unusable, but it is not clear how many days the projector can still be used...
