Embodiment Construction

[0027] Attached below Figure 1-5 The preferred embodiments of the present invention are described in detail, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0028] An LED lamp in the present invention comprises a lamp housing 1, a lampshade 2 covered on the lamp housing 1, and a substrate 3, on which a driving circuit group 4 and an LED chip 5 are arranged, and the driving circuit group 4 It is electrically connected with the LED chip 5, and the LED chip 5 is a high voltage DC LED.

[0029] Due to the use of high-voltage direct current LEDs, the heat emitted by the LED chip 5 is small and will not affect the driving circuit group 4 , so the driving circuit group 4 can also be arranged on the substrate 3 .

[0030] The first embodiment of the present invention is attached figure 1 with 2 As shown, an LED lamp includes a lamp ...

Abstract

The invention discloses an LED (Light Emitting Diode) lamp. The lamp comprises a lamp shell, a lampshade covering the lamp shell and a substrate, wherein the substrate is provided with a drive circuit group and an LED chip, the drive circuit group is electrically connected with the LED chip, and the LED chip is a high voltage DC (Direct Current) LED. The LED lamp comprises a plurality of LED chips which are serially connected with each other, and one of LED chip is electrically connected with the drive circuit group. The drive circuit group is located in the center of the substrate, and the plurality of LED chips are arranged all around the center of the substrate circularly. The rated working voltage of the high voltage DC LED is between 10V and 300V, and the rated working current of the high voltage DC LED is between 10mA and 100mA. The drive circuit group comprises an AC / DC conversion module. By adopting the above structure, the LED lamp has the following advantages of being small in heat dissipating capacity and small in size, and the production cost can be greatly reduced; secondly, the LED lamp is simple to change and high in reuse ratio.

Description

technical field [0001] The invention relates to an LED lamp. Background technique [0002] (Light Emitting Diode), a light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. The current required by the LED is a steady direct current, while the general external power supply uses an alternating current, so the LED lamp must also be provided with an AC-to-DC drive circuit group. [0003] The LED lights in the prior art use traditional LED chips. The rated voltage of a traditional single LED chip is between 3 and 3.3V, and the rated current is about 20mA. Since the rated voltage of a single traditional LED chip is not enough, multiple strings and multiple chips are used. In parallel mode, multiple LED chips make the current of the circuit superimposed to a very high range, the current is generally in the range of 150mA ~ 1500mA, due to the excessive current, according to P = I 2 R, when the input current is too large, the LE...
