Problems solved by technology

Due to the high price of dedicated Flash LED flashlights and dedicated flashlight driver chips, the manufacturing cost of mobile phones has been greatly increased
[0004] Simple Lamp LEDs have high brightness, but they are relatively large in size, generally 3mm to 5mm in diameter. Nowadays, the size of mobile phones is becoming thinner and thinner. Due to structural limitations, Lamp LED chips tend to occupy a large space on the mobile phone and affect the performance of the mobile phone. layout

Embodiment Construction

[0024] The present invention provides a mobile phone with a flashlight function. In order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] The present invention has the mobile phone of flashlight function, as figure 1 and figure 2 As shown, it includes a mobile phone case 101, which may take the form of a technology known in the prior art. And the top, the bottom or the peripheral side of the side of the mobile phone shell 101 are provided with a receiving groove 102, and at least one side-emitting LED chip 103 is arranged in the described receiving groove 102, and the side-emitting LED chip 103 is fixed on the LED chip 103. The chip circuit board 203 is arranged toward the opening of the receiving groove 102 on the casing 101, and two or three side-emitting LED chips can be arranged in the...

Abstract

The invention discloses a mobile phone having a flashlight function. The mobile phone comprises a mobile phone shell, a holding tank is arranged at the top of the mobile phone shell, at least one light emitting diode (LED) chip is arranged in the holding tank, and a lens is arranged on a notch of the holding tank, wherein the notch is formed in front of at least one LED chip; and a control circuit used for controlling the operation of at least one LED chip is arranged in the mobile phone, and the control circuit is connected with a circuit of at least one LED chip. According to the mobile phone, a structure mode in which at least one LED chip is arranged at the top of the mobile phone shell instead of the side or the back of the mobile phone shell is adopted, so the flashlight function of the mobile phone is convenient to realize, the application space of the mobile phone is expanded, the internal space of the mobile phone is saved, the manufacture cost of the mobile phone is reduced, and a phenomenon that at least one LED chip is damaged because of non-constant current is avoided.

Description

technical field [0001] The invention relates to a mobile phone, in particular to a mobile phone with a flashlight function. Background technique [0002] The LED flashlight function is now more and more common in mobile phones. It has the advantages of energy saving, high brightness, long life, easy portability, and low cost. At present, there are two ways to realize the built-in LED flashlight in the mobile phone: a dedicated Flash LED chip and a simple Lamp LED chip. [0003] Most LED flashlights use the same type of chip as the camera flash, which requires a larger drive current and a more expensive flash driver chip, which is generally installed on the back of the phone. Due to the high price of the dedicated Flash LED flashlight and the dedicated flashlight driver chip, the manufacturing cost of the mobile phone has been greatly increased. [0004] Simple Lamp LEDs have high brightness, but they are relatively large in size, generally 3mm to 5mm in diameter. Nowadays,...
